Effects of Ai Chi on balance, quality of life, functional mobility, and motor impairment in patients with Parkinson’s disease

Current interventional model for movement in Parkinson's disease: network meta-analysis based on the improvement of motor ability

Aim

To identify optimally therapeutic exercise interventions for improving motor ability among patients with Parkinson's disease (PD), we conducted a network meta-analysis (NMA) of randomized controlled trials comparing different exercise regimens.

Methods

Relevant RCTs were retrieved by searching PubMed, Embase, Cochrane, Web of Science, CINAHL, CBM, China National Knowledge Infrastructure (CNKI), Wan fang, VIP, and other databases from inception to July 9, 2023 is available in English as the primary language. Exercise outcomes as measured by Movement Disorder Society- Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS-III) score change were evaluated and ranked using STATA software version 18.0. All included studies were assessed for methodological quality using the Cochrane Risk of Bias tool.

Results

The final NMA included 71 studies involving 3,732 participants, 87 intervention experiments, and 27distinct interventions. Although most exercise interventions showed some efficacy (reducing MDS-UPDRS-III score), cumulative ranking probability surface (SUCRA) values indicated that the best exercise interventions for motor function improvement were archery (95.6%), riding a bicycle (80.9%), and binary rhythm dance (80.8%).

Conclusion

An exercise intervention comprising archery, cycling, and(or) binary rhythm dance may yield superior improvements in motor function among patients with Parkinson's disease.

Parkinson's disease motor intervention patterns: a network meta-analysis based on patient motor function

Background

Parkinson's disease is characterized by symptoms such as bradykinesia and rigidity, which worsen as the disease progresses, significantly impacting patients' independence and quality of life. This study utilizes a network meta-analysis approach to quantify information gathered from randomized controlled trials (RCTs) regarding motor interventions that effectively improve the motor function of Parkinson's disease patients, aiming to provide evidence for selecting appropriate exercise intervention strategies for patients.

Methods

A systematic search strategy for randomized controlled trials (RCTs) restricted to English was constructed based on multiple biomedical databases. Databases searched included PubMed, Embase, Cochrane, Web of Science, CINAHL, CBM, China National Knowledge Infrastructure (CNKI), Wan fang, VIP, etc., with searches conducted from inception to July 9, 2023. Two authors screened all studies, extracted data, and used frequency domain analysis methods. Network meta-analysis was performed using STATA software version 18.0 to compare and rank exercises that could effectively improve the motor function of Parkinson's disease patients (measured by indicators such as MDS-UPDRS-III, TUG, BBS, Mini-BES Test, 6MWT scores). Additionally, a series of analyses and evaluations were conducted, such as assessing the methodological quality of included studies using the Cochrane risk of bias tool.

Results

The network meta-analysis included a total of 111 studies involving 5,358 participants, 133 intervention experiments, and 31 intervention measures. Although most exercise interventions showed effectiveness, cumulative ranking curves under the surface (SUCRA) values showed that archery exercise significantly improved patients' MDS-UPDRS-III scores (SUCRA = 95.6%), significantly superior to routine care [standardized mean difference (SMD = 16.92, 95%CI = -28.97, -4.87)]. High-intensity and agility exercise (High strength and agility) referred to as high-intensity exercise or agility training or a combination of both, collectively termed as high-intensity agility training, significantly improved patients' completion time for the time-up-and-go test (SUCRA = 99.7%), (SMD = -7.88, 95%CI = -9.47, -6.28). Dance and Tai Chi exercises significantly improved patients' balance abilities: Mini-Balance Evaluation Systems Test (SUCRA = 77.9%), (SMD = 5.25, 95%CI = -0.42, 10.92) for dance intervention and Berg Balance Scale (SUCRA = 94.7%), (SMD = 11.22, 95%CI = 3.26, 19.18) for Tai Chi intervention. Dance also significantly improved patients' walking ability in the 6-min walk test (SUCRA = 80.5%), (SMD = 71.31, 95%CI = 13.77, 128.84).

Conclusion

Compared to other exercises, archery, dance, Tai Chi, and high-intensity agility exercises demonstrate superior efficacy in improving the motor function of Parkinson's disease patients.

Effects of Tai-Chi on Quality of Life in People With Neurodegenerative Diseases. A systematic Review of Randomised Clinical Trials

OBJECTIVE

This systematic review aimed to evaluate the effects of Tai Chi on the health-related quality of life (HRQoL) of people with neurodegenerative diseases.

DATA SOURCE

This review followed the guidelines of the updated PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020. A systematic search in five electronic databases (Medline via PubMed, Web of Science, Scopus, PEDro, and OTseeker) was performed.

STUDY INCLUSION AND EXCLUSION CRITERIA

Randomized control trials (RCTs) examining Tai Chi interventions to improve HRQoL in patients with neurodegenerative diseases published through March 2023 were included.

DATA EXTRACTION

Data were extracted from each study by two independent researchers into a data extraction form based on the Cochrane recommendations. Methodological quality and risk of bias were assessed.

DATA SYNTHESIS

A meta-analysis was performed using Review Manager 5.3 software.

RESULTS

Of the 439 records that were screened, eight RCTs met the eligibility criteria. They assessed cognitive decline (n = 2) or Parkinson's disease (n = 6). RCT comparison groups included active interventions or usual care. The duration of Tai Chi therapy ranged from 8 to 24 weeks. A sensitivity analysis using a fixed effect model indicated that Tai Chi therapy significantly increased HRQoL [P < 001, SMD (95% CI) = .41 [.21, .60], I2 = 4%].

CONCLUSION

Tai Chi can effectively improve the HRQoL of people with neurodegenerative diseases, but the heterogeneity across intervention was relatively high. Further studies are needed as research into the benefits of Tai Chi in neurodegenerative disease rehabilitation is still limited.

A Retrospective Analysis of Group-Based Boxing Exercise on Measures of Physical Mobility in Patients With Parkinson Disease

OBJECTIVES

The purpose of this retrospective study is to further the limited body of evidence regarding the effects of a group-based boxing intervention for those with Parkinson's disease (PD).

DESIGN

A retrospective cohort study was performed analyzing data collected on outcome measures at 6-month intervals up to 2 years. Individuals participated in the standardized "Rock Steady Boxing" (RSB) program for up to 24 months. Every 6 months, measures were taken of balance (Fullerton Advanced Balance [FAB] Scale), functional mobility (Timed-Up and Go [TUG]), lower extremity strength (30-second Chair Stand [30CST]), and gait speed (10 Meter Walk Test [10MWT]).

METHODS

Statistical significance (P < .05) was determined by a two-tailed t test. Data were collected from RSB-affiliated programs at 4 locations across the southeastern United States. Current and/or past participants in RSB with baseline and at least one subsequent outcome measure were included, resulting in 68 participants (54 male, 14 female, and mean age of 71.2 years ± 8.56 standard deviation).

RESULTS

Statistically significant improvements in FAB scale, TUG, and 30CST over time were found at both 6- and 12-month time points. Significant changes continued through 18 months for FAB and 30CST. No significant changes in 10MWT were observed; however, a moderate effect size was observed at the 1-year point.

CONCLUSIONS

Participants with PD were able to achieve statistically significant improvements in standard measures of functional mobility, balance, and strength within the timeline of this study. Limitations include the retrospective nature, an inability to monitor adherence, and lack of control over pharmaceutical or other interventions.

Comparing the effects of aquatic-based exercise and land-based exercise on balance in older adults: a systematic review and meta-analysis

BACKGROUND

Balance plays a crucial role in the daily activities of older adults. Aquatic-based exercises (AE) are widely conducted as an alternative to land-based exercises (LE). Previous studies have compared AE and LE as effective ways to improve balance and have yielded inconsistent results. Therefore, this review aimed to compare the effects of AE and LE on balance function in older adults.

METHODS

Electronic databases, including PubMed, Web of Science, Scopus, and Embase, were searched. Randomized controlled trials published from January 2003 to June 2023 were included following predetermined criteria. Data extraction was carried out by two independent reviewers. Data synthesis was conducted using RevMan 5.3 software. The fixed-effect model or random-effect model was chosen based on the results of the heterogeneity test. Meta-analysis for the effect sizes of balance outcomes was calculated as standardized mean difference (SMD) with 95% confidence intervals (CI). The quality of the included studies was evaluated using the Physiotherapy Evidence Database (PEDro) scale. This review was registered at PROSPERO CRD42023429557.

RESULTS

A total of 29 studies involving 1486 older adults (with an average age of 66.2 years) were included. Meta-analysis results indicated that AE could improve balance ability based on two tests: the Berg balance scale (BBS: SMD = 1.13, 95% CI 0.25 to 2.00, p = 0.01, I2 = 94%) and the 30-s chair stand test (30 CST: SMD = 2.02, 95% CI 0.50 to 3.54, p = 0.009, I2 = 96%). However, there were no significant differences between the AE group and the LE group in terms of the 6-min walking test (6 MWT: SMD = 0.13, 95% CI -0.16 to 0.43, p = 0.38, I2 = 62%) and time up to go test (TUGT: SMD = 0.44, 95% CI -0.44 to 0.91, p = 0.07, I2 = 85%). Older adults with different health conditions have different gains in different balance measurements after AE intervention and LE intervention.

CONCLUSIONS

Although this was influenced by participant health status, transfer effects, sample size, and other factors, AE offers better benefits than LE for improving balance function in older adults.

Physical exercise for people with Parkinson's disease: a systematic review and network meta-analysis

BACKGROUND

Physical exercise is effective in managing Parkinson's disease (PD), but the relative benefit of different exercise types remains unclear.

OBJECTIVES

To compare the effects of different types of physical exercise in adults with PD on the severity of motor signs, quality of life (QoL), and the occurrence of adverse events, and to generate a clinically meaningful treatment ranking using network meta-analyses (NMAs).

SEARCH METHODS

An experienced information specialist performed a systematic search for relevant articles in CENTRAL, MEDLINE, Embase, and five other databases to 17 May 2021. We also searched trial registries, conference proceedings, and reference lists of identified studies up to this date.

SELECTION CRITERIA

We included randomized controlled trials (RCTs) comparing one type of physical exercise for adults with PD to another type of exercise, a control group, or both.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data. A third author was involved in case of disagreements. We categorized the interventions and analyzed their effects on the severity of motor signs, QoL, freezing of gait, and functional mobility and balance up to six weeks after the intervention using NMAs. Two review authors independently assessed the risk of bias using the risk of bias 2 (RoB 2) tool and rated the confidence in the evidence using the CINeMA approach for results on the severity of motor signs and QoL. We consulted a third review author to resolve any disagreements. Due to heterogeneous reporting of adverse events, we summarized safety data narratively and rated our confidence in the evidence using the GRADE approach.

MAIN RESULTS

We included 154 RCTs with a total of 7837 participants with mostly mild to moderate disease and no major cognitive impairment. The number of participants per study was small (mean 51, range from 10 to 474). The NMAs on the severity of motor signs and QoL included data from 60 (2721 participants), and 48 (3029 participants) trials, respectively. Eighty-five studies (5192 participants) provided safety data. Here, we present the main results. We observed evidence of beneficial effects for most types of physical exercise included in our review compared to a passive control group. The effects on the severity of motor signs and QoL are expressed as scores on the motor scale of the Unified Parkinson's Disease Rating Scale (UPDRS-M) and the Parkinson's Disease Questionnaire 39 (PDQ-39), respectively. For both scales, higher scores denote higher symptom burden. Therefore, negative estimates reflect improvement (minimum clinically important difference: -2.5 for UPDRS-M and -4.72 for PDQ-39). Severity of motor signs The evidence from the NMA (60 studies; 2721 participants) suggests that dance and gait/balance/functional training probably have a moderate beneficial effect on the severity of motor signs (dance: mean difference (MD) -10.18, 95% confidence interval (CI) -14.87 to -5.36; gait/balance/functional training: MD -7.50, 95% CI -11.39 to -3.48; moderate confidence), and multi-domain training probably has a small beneficial effect on the severity of motor signs (MD -5.90, 95% CI -9.11 to -2.68; moderate confidence). The evidence also suggests that endurance, aqua-based, strength/resistance, and mind-body training might have a small beneficial effect on the severity of motor signs (endurance training: MD -5.76, 95% CI -9.78 to -1.74; aqua-based training: MD -5.09, 95% CI -10.45 to 0.40; strength/resistance training: MD -4.96, 95% CI -9.51 to -0.40; mind-body training: MD -3.62, 95% CI -7.24 to 0.00; low confidence). The evidence is very uncertain about the effects of "Lee Silverman Voice training BIG" (LSVT BIG) and flexibility training on the severity of motor signs (LSVT BIG: MD -6.70, 95% CI -16.48 to 3.08; flexibility training: MD 4.20, 95% CI -1.61 to 9.92; very low confidence). Quality of life The evidence from the NMA (48 studies; 3029 participants) suggests that aqua-based training probably has a large beneficial effect on QoL (MD -15.15, 95% CI -23.43 to -6.87; moderate confidence). The evidence also suggests that mind-body, gait/balance/functional, and multi-domain training and dance might have a small beneficial effect on QoL (mind-body training: MD -7.22, 95% CI -13.57 to -0.70; gait/balance/functional training: MD -6.17, 95% CI -10.75 to -1.59; multi-domain training: MD -5.29, 95% CI -9.51 to -1.06; dance: MD -3.88, 95% CI -10.92 to 3.00; low confidence). The evidence is very uncertain about the effects of gaming, strength/resistance, endurance, and flexibility training on QoL (gaming: MD -8.99, 95% CI -23.43 to 5.46; strength/resistance training: MD -6.70, 95% CI -12.86 to -0.35; endurance training: MD -6.52, 95% CI -13.74 to 0.88; flexibility training: MD 1.94, 95% CI -10.40 to 14.27; very low confidence). Adverse events Only 85 studies (5192 participants) provided some kind of safety data, mostly only for the intervention groups. No adverse events (AEs) occurred in 40 studies and no serious AEs occurred in four studies. AEs occurred in 28 studies. The most frequently reported events were falls (18 studies) and pain (10 studies). The evidence is very uncertain about the effect of physical exercise on the risk of adverse events (very low confidence). Across outcomes, we observed little evidence of differences between exercise types.

AUTHORS' CONCLUSIONS

We found evidence of beneficial effects on the severity of motor signs and QoL for most types of physical exercise for people with PD included in this review, but little evidence of differences between these interventions. Thus, our review highlights the importance of physical exercise regarding our primary outcomes severity of motor signs and QoL, while the exact exercise type might be secondary. Notably, this conclusion is consistent with the possibility that specific motor symptoms may be treated most effectively by PD-specific programs. Although the evidence is very uncertain about the effect of exercise on the risk of adverse events, the interventions included in our review were described as relatively safe. Larger, well-conducted studies are needed to increase confidence in the evidence. Additional studies recruiting people with advanced disease severity and cognitive impairment might help extend the generalizability of our findings to a broader range of people with PD.

The immediate and lasting balance outcomes of clinical falls-prevention programs: A non-randomised study

PURPOSE

Exercise-based falls-prevention programs are cost-effective population-based approaches to reduce the risk of falling for older adults. The aim was to evaluate the short-term and long-term efficacy of three existing falls-prevention programs.

METHODS

A non-randomized study design was used to compare the immediate-post and long-term physical outcome measures for three falls prevention programs; one high-level land-based program, one low-level land-based program and a water-based Ai Chi program. Timed-up-and-go (TUG), five-times sit-to-stand (5xSTS), six-minute walk test (6MWT) and six-meter walk test were assessed at baseline, post-program, and at six-months follow-up. Linear mixed models were used to analyze between- and within- group differences, with the high-level land-based program used as the comparator.

RESULTS

Thirty-two participants completed post-program assessment and 26 returned for follow-up. There was a difference in the age (years) of participants between programs (p = 0.049). The intercept for TUG and six-meter walk test time was 47.70% (23.37, 76.83) and 32.31s (10.52, 58.41), slower for the low-level group and 40.49% (17.35, 69.89) and 36.34s (12.75, 64.87), slower for the Ai Chi group (p < 0.01), compared with the high-level group. Mean time taken to complete the TUG was less both immediately post-program and at 6-month follow-up (p = 0.05). Walking speed for the six-meter walk test was only faster at six-months (p < 0.05). The 5xSTS duration was significantly reduced only at post-intervention (p < 0.05).

CONCLUSION

These results indicate land-based and water-based falls-prevention programs improve physical outcome measures associated with falls-risk and many improvements are maintained for six months after the completion of the program. (Retrospective trial registration: ACTRN1262300119069).

High-frequency multimodal training with a focus on Tai Chi in people with Parkinson's disease: a pilot study

Background and objectives

Cognitive decline is an important and common complication in patients with Parkinson's disease (PD) since it significantly reduces the quality of life. A breakthrough in treating and preventing cognitive decline in PD remains to be achieved. This study aimed to evaluate the effectiveness of high-frequency and intensive multimodal training in improving motor and cognitive function.

Methods

Twenty-eight patients diagnosed with idiopathic PD completed a comprehensive neuropsychological test battery and were neurologically examined. The patients of the intervention group (n = 15) underwent 2 weekly sessions of Tai Chi therapy over 4 weeks and participated in an individually tailored training program consisting of two modules (smartphone-based speech training and cognitive training). A matched control group consisted of n = 13 patients with PD who received computer-assisted cognitive training. The data were analyzed with repeated-measures ANOVA.

Results

Four weeks of high-frequency training showed significant effects on verbal and figural episodic memory and visuospatial function in the intervention group. Compared to the control group, the cognitive performance of the intervention group improved significantly in visuospatial function and figural episodic memory. A significant improvement was also shown in the intervention group in the Tinetti Mobility Test and the Epworth Sleepiness Scale. The significant effects in the Tinetti mobility test remained after the 6 months follow-up. After the intervention, the patients reported high motivation and satisfaction with the multimodal training.

Conclusion

In patients with PD, a multimodal training program not only improves gait and stability but may also contribute to improving cognition.

Effect of aquatic exercise programs according to the International Classification of Functionality, Disability and Health domains in individuals with Parkinson's disease: a systematic review and meta-analysis with GRADE quality assessment

PURPOSE

To investigate the effects of aquatic exercise programs (AEP) in body structure and function, activity, and participation outcomes in individuals with Parkinson's disease (PD) with mild to moderate disability levels.

METHODS

Six databases were searched from inception until November 2022. Randomized clinical trials that used AEP alone, AEP combined and/or compared two types of AEP were included. The quality of evidence was assessed by the GRADE approach and the standardized mean differences (SMD) were calculated the meta-analysis.

RESULTS

Twelve studies (n = 380) were included. AEP alone was superior to active control in improving body structure and function outcome: postural balance (low evidence, SMD = 0.47, p = 0.02). No statistically significant differences were found for the other body structure and function outcomes: lower limb muscle strength (p = 0.14) and depressive symptoms (p = 0.79), activity outcomes: mobility (p = 0.32) and participation outcomes: quality of life (p = 0.05). AEP combined showed no statistically significant difference for the outcomes of body structure and function: postural balance (p = 0.11) and activity: mobility (p = 0.21) when compared to active control.

CONCLUSION

AEP showed positive effects on body structure and function outcome (postural balance) in individuals with PD with mild to moderate disability levels while, no significant improvements were noticed for activity and participation outcomes.IMPLICATIONS FOR REHABILITATIONOur findings indicate that aquatic exercise programs (AEP) lead to significant improvements on body structure and function (i.e., postural balance) in individuals with Parkinson's disease (PD).The AEP evaluated in this study implemented postural balance, gait, single and double training, as well as aerobic exercises, trunk mobility exercises, and Ai Chi.The average duration, frequency, and total time implemented were 50 minutes, three times a week, for seven weeks, respectively.Considering the potential benefits identified in this study, AEP can be recommended as an adjunct treatment strategy for individuals with PD.Additionally, the use of the International Classification of Functionality, Disability and Health on the development of rehabilitation treatment plans is advised.

Effects of Aquatic Exercise and Floor Curling on Balance Ability and Lower Limb Muscle Strength in Children with Intellectual Disabilities: A Pilot Study in China

Children with intellectual disabilities often face challenges in balance ability and lower limb muscle strength, which negatively impact their daily lives and motor function. Therefore, it is crucial to enhance the balance ability and lower limb muscle strength of children with intellectual disabilities. This study aimed to investigate the effects of a 12-week aquatic exercise and floor curling intervention on the balance ability and lower limb muscle strength of children with intellectual disabilities. Forty-two participants were randomly assigned to the aquatic exercise group, floor curling group, and control group. The aquatic exercise and floor curling groups received a 12-week intervention, while the control group engaged in supervised free activities. The participants' balance ability and lower limb muscle strength were assessed using the Berg Balance Scale and a muscle strength testing device before and after the intervention. The results showed significant improvements in balance ability and lower limb muscle strength for both the aquatic exercise group and the floor curling group after the intervention. The aquatic exercise group demonstrated an average improvement of 10.84% in balance ability and an overall average improvement of 16.28% in lower limb muscle strength. The floor curling group showed an average improvement of 9.04% in balance ability and an overall average improvement of 15.67% in lower limb muscle strength. These improvement results were statistically significant (p < 0.05) and ranged from medium to large effect sizes (d = 0.5~0.8). The findings of this study validate the positive effects of aquatic exercise and floor curling on the balance ability and lower limb muscle strength of children with intellectual disabilities. These interventions can be considered effective approaches for functional rehabilitation in children with intellectual disabilities.

Exercise Made Accessible: the Merits of Community-Based Programs for Persons with Parkinson's Disease

PURPOSE OF REVIEW

Many studies have identified positive effects of physiotherapy and exercise for persons with Parkinson's disease (PD). Most work has thus far focused on the therapeutic modality of exercise as used within physiotherapy programs. Stimulated by these positive findings, there is now a strong move to take exercise out of the clinical setting and to deliver the interventions in the community. Although the goals and effects of many such community-based exercise programs overlap with those of physiotherapy, it has also become more clear that both exercise modalities also differ in various ways. Here, we aim to comprehensively review the evidence for community-based exercise in PD.

RECENT FINDINGS

Many different types of community-based exercise for people with PD are emerging and they are increasingly being studied. There is a great heterogeneity considering the types of exercise, study designs, and outcome measures used in research on this subject. While this review is positive regarding the feasibility and potential effects of community-based exercise, it is also evident that the general quality of these studies needs improvement. By focusing on community-based exercise, we hope to generate more knowledge on the effects of a wide range of different exercise modalities that can be beneficial for people with PD. This knowledge may help people with PD to select the type and setting of exercise activity that matches best with their personal abilities and preferences. As such, these insights will contribute to an improved self-management of PD.

"Out and proud…. in all your shaking glory" the wellbeing impact of a dance program with public dance performance for people with Parkinson's disease: a qualitative study

PURPOSE

To explore if and how Parkinson's disease dance class participation and public performance contributes to perceptions of wellbeing.

MATERIALS AND METHODS

A qualitative design using audio-recorded one-on-one semi-structured interviews with five class participants and three teachers/volunteers from two metropolitan Dance for Wellbeing class locations. Data were inductively thematically analysed by three researchers.

RESULTS

Five themes illustrated the experience of dance class and performance for people with Parkinson's Disease: 1) 'the enabling learning environment'; 2) 'physical benefits from class participation; 3) 'mental/psychological benefits from class participation'; 4) 'social benefits from class participation; 5) 'sense of self and life engagement from class participation'. Themes 4 and 5 in particular were considered to be 'magnified by public performance', providing an opportunity for solidarity within the group and a supportive avenue for "coming out" and living publicly with the PD diagnosis.

CONCLUSION

Dance performance magnifies health and wellbeing experiences of people with Parkinson's disease when part of an enabling, inclusive and emotionally and physically safe learning dance class environment. Elements of holistic benefits, as well as the fun and playful nature of the experience may be important elements to consider for motivation, recruitment and retention in this population.IMPLICATIONS FOR REHABILITATIONRehabilitation professionals should consider the use of dance class as an art-based activity that has a holistic therapeutic benefit.Flexible and fun environments are constructive for dancers to sustain attendance and interest.Rehabilitation professionals can be cognisant of the impact of public dance performance as 'coming out' with Parkinson's Disease.

Whether mindfulness-guided therapy can be a new direction for the rehabilitation of patients with Parkinson's disease: a network meta-analysis of non-pharmacological alternative motor-/sensory-based interventions

Background

The treatment for Parkinson's disease (PD) consumes a lot of manpower and financial resources. Non-pharmacological alternative motor-/sensory-based interventions are optimized for the rehabilitation of PD patients. Mindfulness-based therapy shows ideal efficacy, but the diversity of the therapy brings difficulties to the selection of clinicians and patients.

Methods

Network meta-analysis in the Bayesian framework was used to evaluate the efficacy of non-pharmacological alternative motor-/sensory-based interventions in improving motor and non-motor symptoms in PD patients.

Results

A total of 58 studies (2,227 patients) were included. Compared with the non-intervention group, qigong was associated with improved outcomes in the Timed Up and Go (TUG) test (mean difference (MD) -5.54, 95% confidence interval (CI) -8.28 to -2.77), and UPDRS-I (MD -15.50, 95% CI -19.93 to -7.63). Differences between non-pharmacological alternative motor-/sensory-based interventions were not significant for PDQ-39, UPDRS-I, or UPDRS-II; however, qigong was superior to dance (MD -3.91, 95% CI -6.90 to -0.95), Tai Chi (MD -3.54, 95% CI -6.53 to -0.69), acupuncture (MD -6.75, 95% CI -10.86 to -2.70), music (MD -3.91, 95% CI -7.49 to -0.48), and exercise (MD -3.91, 95% CI -6.49 to -1.33) in the TUG test.

Conclusion

This network meta-analysis supports mindfulness-based therapy (e.g., qigong, yoga, and Tai Chi) as a preferred non-pharmacological alternative motor-/sensory-based intervention for PD rehabilitation.

Physical Exercise Interventions on Quality of Life in Parkinson Disease: A Network Meta-analysis

BACKGROUND AND PURPOSE

Physical exercise is considered an effective intervention for maintaining or improving quality of life (QoL) in patients with Parkinson disease (PD), but there is no evidence showing which type of physical exercise intervention has more positive effects. This systematic review and meta-analysis aimed to synthesize the evidence regarding the effectiveness of exercise interventions on improving QoL in patients with PD, comparing different types of exercise interventions.

METHODS

A literature search was conducted through January 2022. The methodological quality of the trials was assessed using the Cochrane risk of bias tool RoB2. For the meta-analysis, physical exercise interventions were classified into 5 training categories: resistance, endurance, alternative exercises, dance, and sensorimotor interventions. A standard meta-analysis and network meta-analysis were carried out to evaluate the efficacy of the different types of physical exercise interventions.

RESULTS

The search retrieved 2451 studies, 48 of which were included in this network meta-analysis with a total of 2977 patients with PD. The indirect effects of the network meta-analysis showed positive results for alternative exercises (-0.46; 95% confidence interval [CI]: -0.76, -0.16), dance (-0.63; 95% CI: -1.08, -0.17), and sensorimotor interventions (-0.23; 95% CI: -0.40, -0.07) versus control comparisons.

DISCUSSION AND CONCLUSIONS

More research is needed to determine the types of physical exercise interventions that are most beneficial and for which conditions of the disease they have the most positive effects.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A398 ).

Effect of Exercise on Motor Symptoms in Patients With Parkinson's Disease: A Network Meta-analysis

BACKGROUND

Although the pharmacological approach may help with motor symptoms in Parkinson's disease (PD), they are clearly not the complete solution. Thus, for the treatment of PD motor symptoms, physical activity has been proposed as an effective intervention.

METHODS

A systematic search in MEDLINE, Web of Science, Scopus, and Cochrane Central Register of Controlled Trials databases was conducted to identify randomized controlled trials testing the effectiveness of exercise interventions on motor symptoms of PD. Physical exercise interventions were divided into 9 categories: endurance, resistance, combined, balance, dance, alternative exercises, body weight supported, sensorimotor interventions including endurance exercise, and sensorimotor interventions not including endurance exercise. A pairwise meta-analysis for direct and indirect comparisons between intervention and control/nonintervention groups was carried out.

RESULTS

Fifty-six studies met the inclusion criteria, including 2740 participants, aged between 57.6 and 77.7 years. Results showed that sensorimotor training including endurance (effect size [ES]-1.09; 95% confidence interval [CI], -1.68 to -0.50), resistance (ES-0.82; 95% CI, -1.23 to -0.41), and dance (ES-0.64; 95% CI, -1.24 to -0.05) were the most effective physical activity interventions for mitigating PD motor symptoms.

CONCLUSION

Physical activity interventions are an effective strategy for the management of motor symptoms in patients with PD. Among the different exercise intervention programs, those including more complex and demanding activities (sensorimotor training including endurance, resistance, and dance) seem to be the most effective physical activity interventions.

A meta-analysis of exercise intervention and the effect on Parkinson's Disease symptoms

Parkinson's disease (PD) is a progressive neurodegenerative disease that is distinguished by tremors at rest, bradykinesia, hypokinesia, and postural instability, resulting in a progressive decline in performance of everyday activities. The non-motor symptoms that occur can include pain, depression, cognitive dysfunction, sleep issues, and anxiety (among others). Functionality is tremendously impaired by physical as well as non-motor symptoms. Recent treatment has begun to incorporate non-conventional interventions that are more functional and tailored to the patients with PD. The purpose of this meta-analysis was to determine the effectiveness of exercise interventions at alleviating PD symptoms, as measured by the Unified Parkinson's Disease Rating Scale (UPDRS). Additionally, this review qualitatively explored whether endurance-based or non-endurance based exercise interventions were more beneficial at alleviating PD symptoms. Two reviewers screened the title and abstract records (n = 668) found in the initial search. Subsequently the reviewers completed full-text screening of the remaining articles for inclusion.. Following this, a total of 25 articles were considered to be eligible and included in the review and data was extracted for meta-analysis. The interventions lasted from 4 to 26 weeks. Results indicated a positive overall effect of therapeutic exercise on patients with PD, where the overall d-index was 0.155. Qualitatively no difference was observed between aerobic and non-aerobic forms of exercise.

Effects of aquatic exercise on the improvement of lower-extremity motor function and quality of life in patients with Parkinson's disease: A meta-analysis

Objective: To systematically evaluate the effect of aquatic exercise interventions on the improvement of lower-extremity motor function and quality of life in patients with Parkinson's disease. Methods: Two researchers independently searched the literature using the PubMed, Web of Science, Embase, and Cochrane Library databases. The search period was from the establishment of the database to December 2021. The subject heading search included "hydrotherapy," "hydro therapies," "hydro therapeutics," "water therapy," "aquatic exercise therapy," "aquatic therapy," "water-based exercise," "Parkinson," "Parkinson disease," "Parkinson's disease," "Parkinson's syndrome," "primary Parkinsonism," "paralysis agitans," and "randomized controlled trial (RCT)." Result: A total of 698 articles were retrieved from the four databases by searching for subject headings, and 10 RCT articles were finally included. The balance ability of aquatic exercise in patients with Parkinson's disease (weighted mean differences [WMD] = 2.234, 95% CI: 1.112-3.357, Z = 3.9, p < 0.01), walking ability (WMD = -0.911, 95% CI: -1.581 to -0.241, Z = 2.67, p < 0.01), and quality of life (WMD = -5.057, 95% CI: -9.610 to -0.504, Z = 2.18, p = 0.029) were improved, but there was no significant difference in motor function (WMD = -0.328, 95% CI: -1.781 to 1.125, Z = 0.44, p = 0.658). Conclusion: Compared with conventional rehabilitation therapy, aquatic exercise can effectively improve balance, walking ability, and quality of life in patients with Parkinson's disease. However, it had no obvious effect on improving motor function. This study was limited by the number and quality of the included studies, and more high-quality studies are needed to verify this.

Physical exercise for people with Parkinson's disease: a systematic review and network meta-analysis

BACKGROUND

Physical exercise is effective in managing Parkinson's disease (PD), but the relative benefit of different exercise types remains unclear.

OBJECTIVES

To compare the effects of different types of physical exercise in adults with PD on the severity of motor signs, quality of life (QoL), and the occurrence of adverse events, and to generate a clinically meaningful treatment ranking using network meta-analyses (NMAs).

SEARCH METHODS

An experienced information specialist performed a systematic search for relevant articles in CENTRAL, MEDLINE, Embase, and five other databases to 17 May 2021. We also searched trial registries, conference proceedings, and reference lists of identified studies up to this date.

SELECTION CRITERIA

We included randomized controlled trials (RCTs) comparing one type of physical exercise for adults with PD to another type of exercise, a control group, or both.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data. A third author was involved in case of disagreements.  We categorized the interventions and analyzed their effects on the severity of motor signs, QoL, freezing of gait, and functional mobility and balance up to six weeks after the intervention using NMAs. Two review authors independently assessed the risk of bias using the risk of bias 2 (RoB 2) tool and rated the confidence in the evidence using the CINeMA approach for results on the severity of motor signs and QoL. We consulted a third review author to resolve any disagreements. Due to heterogeneous reporting of adverse events, we summarized safety data narratively and rated our confidence in the evidence using the GRADE approach.

MAIN RESULTS

We included 156 RCTs with a total of 7939 participants with mostly mild to moderate disease and no major cognitive impairment. The number of participants per study was small (mean 51, range from 10 to 474). The NMAs on the severity of motor signs and QoL included data from 71 (3196 participants), and 55 (3283 participants) trials, respectively. Eighty-five studies (5192 participants) provided safety data. Here, we present the main results. We observed evidence of beneficial effects for most types of physical exercise included in our review compared to a passive control group. The effects on the severity of motor signs and QoL are expressed as scores on the motor scale of the Unified Parkinson Disease Rating Scale (UPDRS-M) and the Parkinson's Disease Questionnaire 39 (PDQ-39), respectively. For both scales, higher scores denote higher symptom burden. Therefore, negative estimates reflect improvement (minimum clinically important difference: -2.5 for UPDRS-M and -4.72 for PDQ-39). Severity of motor signs The evidence from the NMA (71 studies; 3196 participants) suggests that dance has a moderate beneficial effect on the severity of motor signs (mean difference (MD) -10.32, 95% confidence interval (CI) -15.54 to -4.96; high confidence), and aqua-based, gait/balance/functional, and multi-domain training might have a moderate beneficial effect on the severity of motor signs (aqua-based: MD -7.77, 95% CI -13.27 to -2.28; gait/balance/functional: MD -7.37, 95% CI -11.39 to -3.35; multi-domain: MD -6.97, 95% CI -10.32 to -3.62; low confidence). The evidence also suggests that mind-body training and endurance training might have a small beneficial effect on the severity of motor signs (mind-body: MD -6.57, 95% CI -10.18 to -2.81; endurance: MD -6.43, 95% CI -10.72 to -2.28; low confidence). Flexibility training might have a trivial or no effect on the severity of motor signs (MD 2.01, 95% CI -4.82 to 8.98; low confidence). The evidence is very uncertain about the effects of strength/resistance training and "Lee Silverman Voice training BIG" (LSVT BIG) on the severity of motor signs (strength/resistance: MD -6.97, 95% CI -11.93 to -2.01; LSVT BIG: MD -5.49, 95% CI -14.74 to 3.62; very low confidence). Quality of life The evidence from the NMA (55 studies; 3283 participants) suggests that aqua-based training probably has a large beneficial effect on QoL (MD -14.98, 95% CI -23.26 to -6.52; moderate confidence). The evidence also suggests that endurance training might have a moderate beneficial effect, and that gait/balance/functional and multi-domain training might have a small beneficial effect on QoL (endurance: MD -9.16, 95% CI -15.68 to -2.82; gait/balance/functional: MD -5.64, 95% CI -10.04 to -1.23; multi-domain: MD -5.29, 95% CI -9.34 to -1.06; low confidence). The evidence is very uncertain about the effects of mind-body training, gaming, strength/resistance training, dance, LSVT BIG, and flexibility training on QoL (mind-body: MD -8.81, 95% CI -14.62 to -3.00; gaming: MD -7.05, 95% CI -18.50 to 4.41; strength/resistance: MD -6.34, 95% CI -12.33 to -0.35; dance: MD -4.05, 95% CI -11.28 to 3.00; LSVT BIG: MD 2.29, 95% CI -16.03 to 20.44; flexibility: MD 1.23, 95% CI -11.45 to 13.92; very low confidence). Adverse events Only 85 studies (5192 participants) provided some kind of safety data, mostly only for the intervention groups. No adverse events (AEs) occurred in 40 studies and no serious AEs occurred in four studies. AEs occurred in 28 studies. The most frequently reported events were falls (18 studies) and pain (10 studies). The evidence is very uncertain about the effect of physical exercise on the risk of adverse events (very low confidence). Across outcomes, we observed little evidence of differences between exercise types.

AUTHORS' CONCLUSIONS

We found evidence of beneficial effects on the severity of motor signs and QoL for most types of physical exercise for people with PD included in this review, but little evidence of differences between these interventions. Thus, our review highlights the importance of physical exercise regarding our primary outcomes severity of motor signs and QoL, while the exact exercise type might be secondary. Notably, this conclusion is consistent with the possibility that specific motor symptoms may be treated most effectively by PD-specific programs. Although the evidence is very uncertain about the effect of exercise on the risk of adverse events, the interventions included in our review were described as relatively safe. Larger, well-conducted studies are needed to increase confidence in the evidence. Additional studies recruiting people with advanced disease severity and cognitive impairment might help extend the generalizability of our findings to a broader range of people with PD.

The mechanism of exercise for pain management in Parkinson's disease

The research and clinical applications of exercise therapy to the treatment of Parkinson's disease (PD) are increasing. Pain is among the important symptoms affecting the daily motor function and quality of life of PD patients. This paper reviewed the progress of research on different exercise therapies for the management of pain caused by PD and described the role and mechanism of exercise therapy for pain relief. Aerobic exercise, strength exercise, and mind-body exercise play an effective role in pain management in PD patients. The pain suffered by PD patients is divided into central neuropathic, peripheral neuropathic, and nociceptive pain. Different types of pain may coexist with different mechanistic backgrounds and treatments. The analgesic mechanisms of exercise intervention in PD-induced pain include altered cortical excitability and synaptic plasticity, the attenuation of neuronal apoptosis, and dopaminergic and non-dopaminergic analgesic pathways, as well as the inhibition of oxidative stress. Current studies related to exercise interventions for PD-induced pain suffer from small sample sizes and inadequate research of analgesic mechanisms. The neurophysiological effects of exercise, such as neuroplasticity, attenuation of neuronal apoptosis, and dopaminergic analgesic pathway provide a sound biological mechanism for using exercise in pain management. However, large, well-designed randomized controlled trials with improved methods and reporting are needed to evaluate the long-term efficacy and cost-effectiveness of exercise therapy for PD pain.

Which type of mind-body exercise is most effective in improving functional performance and quality of life in patients with Parkinson's disease? A systematic review with network meta-analysis

BACKGROUND

Several studies have investigated the effect of mind-body exercise (MBE) on functional performance and health-related quality of life (HRQoL) in Parkinson's disease (PD), but it is still very difficult for clinicians to make informed decision on the best mind-body exercise for PD.

PURPOSE

We analyzed the relative efficacy of MBE (yoga, Tai-Chi, Pilates, Qigong, and dance) in improving functional performance and HRQoL in patients with PD.

METHODS

A systematic review of randomized controlled trials (RCTs) was performed using network meta-analysis (NMA), searching the following databases: Cochrane, Web of Science, and PubMed using specific keywords until December 28, 2021, assessing the effects of MBE on functional performance and HRQoL in patients with PD.

RESULTS

This review included 60 RCTs with 2037 participants. A ranking of MBE for modifying various aspects of functional performance and HRQoL was achieved. Pairwise NMA showed Pilates to be the most effective in improving functional mobility (MD: - 3.81; 95% CI (- 1.55, - 6.07) and balance performance (SMD: 2.83; 95% CI (1.87, 3.78). Yoga (MD: - 5.95; 95% CI (- 8.73, - 3.16) and dance (MD: - 5.87; 95% CI (- 8.73, - 3.01) to be the most effective in improving motor function, whereas Qigong (MD: 0.32; 95% CI (0.00, 0.64) was most effective in improving gait speed. Considering HRQoL, dance was found to be the most effective (SMD: - 0.36; 95% CI (- 0.70, -0.01).

CONCLUSION

MBE should be considered an effective strategy for improving functional performance and HRQoL in patients with PD. The most effective MBE intervention varied with the functional performance domain. Dance was an effective exercise for improving HRQoL among people with PD.

Effects of an Aquatic Physical Exercise Program on Ventilatory Parameters in People with Parkinson’s Disease

Problems in the respiratory system are the main cause of death in Parkinson’s disease (PD). Ventilatory limitations can also be part of a vicious cycle involving physical-functional limitations (e.g., walking difficulties) and the patients’ perception of fatigue. The objective of this study was to analyze the effects of an aquatic physical exercise intervention program on ventilatory parameters, perception of fatigue, and gait capacity in participants with PD. This quasi-experimental study had a single group with repeated measures in four assessments, proposing an aquatic physical exercise intervention program. The inclusion criteria encompassed being in levels 1 to 4 on the Hoehn and Yahr scale and having a medical certificate for the activities. Assessments took place at 3-month intervals between them—the first period was the control, the second following the intervention, and the third period was the follow-up. The intervention had 25 biweekly sessions over 3 months. A total of 13 people (71.3 ± 5.61 years old) participated in the intervention, without significant differences in the control period. Between the intervention assessments, they had statistically significant differences in MIP, MEP, FVC, Tiffeneau index, MVV, and fatigue. The study demonstrated that the aquatic physical exercise intervention was effective for ventilatory outcomes and fatigue in people with PD.

The effects of different types of Tai Chi exercises on motor function in patients with Parkinson's disease: A network meta-analysis

Background

Tai Chi can show improvement in balance and motor ability of elderly patients with PD. However, there were few reports on differences in outcomes associated with different types of Tai Chi on improving exercise capacity in elderly patients with PD. We compared the improvement of motor function in Parkinson's patients with different types of Tai Chi, for finding an optimal intervention.

Methods

The following databases were searched from the beginning of the establishment of each database to 10 January 2022: PubMed, EMBASE, The Cochrane Library, CNKI, Wanfang Database, and VIP Database. Randomized controlled trials incorporating different types of Tai Chi for PD were included. The outcome measures were UPDRSIII and BBS. NMA was conducted using Stata 15.0 based on a frequentist framework.

Results

A total of twenty trials were eligible, including 996 participants. In conventional meta-analysis, as for the UPDRSIII scale, 24-form simplified Tai Chi (SMD = −1.272, 95% CI [−2.036, −0.508], P < 0.05, I² > 50%), Tai Chi exercise program (SMD = −0.839, 95% CI [−1.828, 0.151], P > 0.05, I² > 50%), 8-form simplified Yang style Tai Chi (SMD = −0.325, 95% CI [−1.362, 0.713], P > 0.05, I² > 50%), and 8-form simplified Chen style Tai Chi (SMD = −0.28, 95% CI [−0.97, 0.42], P > 0.05, I² > 50%) were statistically more efficient than the control group. For BBS outcome, 24-form simplified Tai Chi (MD = 3.979, 95% CI [3.364, 4.595], P < 0.05, I² <50%), Tai Chi exercise program (MD = 5.00, 95% CI [2.07, 7.93], P > 0.05, I² > 50%), and 8-form simplified Chen style Tai Chi (MD = 1.25, 95% CI [0.52, 1.98], P < 0.05, I² > 50%) were better than the control group. In the network meta-analysis, the results of UPDRSIII were as follows: 24-form > TCEP > 8-form YS > 8-form CS > control. The ranking probability of BBS was as follows: TCEP > 24-form > 8-form CS > control.

Conclusion

Among the four treatments studied, 24-form Tai Chi and Tai Chi exercise programs have shown better efficacy than other types. Our study provides new insights into exercise therapy for PD and may contribute to the formulation of a clinical exercise prescription.

Community Exercise: A New Tool for Personalized Parkinson’s Care or Just an Addition to Formal Care?

Physiotherapy and exercise are associated with motor and non-motor benefits in Parkinson’s disease (PD). Community exercise programs may increase ongoing exercise participation and help people with Parkinson’s disease actively participate in their health management. But there is still limited knowledge about these programs regarding their benefits, safety, implications over the long-term, and effective implementation. These questions could hold relevant clinical implications. In this perspective article, we identify the current challenges and reflect upon potential solutions to help community exercise to be implemented as an additional anchor to personalize management models for Parkinson’s disease.

Efficacy of Traditional Chinese Exercise in Improving Gait and Balance in Cases of Parkinson's Disease: A Systematic Review and Meta-analysis

Background

The efficacy of traditional Chinese exercise (TCE)-based intervention in the improvement of motor function in patients with Parkinson's disease (PD) is controversial. The present study aimed to assess the effects of TCE on balance and gait outcomes, as well as motor symptoms in individuals with PD, and evaluate potential discrete moderators such as TCE dosage-related variables.

Method

PubMed, Embase, Cochrane's Library, Web of Science, Medline, and Scopus were systematically searched from their dates of inception to February 2022. All studies were randomized controlled trials (RCTs) of TCE-based interventions for PD. The treatment effects were estimated using a random-effect meta-analysis model with standardized mean differences (Hedges' g). The Physiotherapy Evidence Database was used to evaluate the methodological quality of the study.

Result

Fifteen studies involving a total of 873 participants were included in the final analysis. The meta-analytic findings revealed significant improvements in balance outcomes [Berg Balance Scales (BBS) (g = 0.83, 95% CI = 0.37–1.29, p = 0.000, I² = 84%), time up and go (TUG) (g = −0.80, 95% CI = −1.13– −0.47, p = 0.000, I² = 81%), and the one legged blind balance test (g = 0.49, 95% CI = 0.13–0.86, p = 0.01, I² = 10%)], as well as gait outcomes [gait velocity (g = 0.28, 95% CI = 0.02–0.54, p = 0.04, I² = 64%), 6-min walking test (6MWT) (g = 0.32, 95% CI 0.01–0.62, p = 0.04, I²= 15%), stride length (g = 0.25, 95% CI = 0.08–0.41, p = 0.003, I² = 42%)], and motor symptoms [Unified Parkinson's Disease Rating Scale part III (UPDRS-III) (g = −0.77, 95% CI = −1.06– −0.48, p = 0.000, I² = 76%)]. However, cadence (g = −0.03) and step length (g = 0.02) did not differ significantly. The moderator shows that the effects of TCE on BBS and gait velocity were moderated by Pedro score, exercise type, control group type, and number of sessions. Meta-regression found that TCE (exercise duration, number of sessions, and session duration) was significantly associated with improved UPDRS-III and BBS scores.

Conclusion

These findings provide evidence for the therapeutic benefits of TCE as an adjunct therapy for patients with PD. TEC dosage (high-intensity long sessions) may moderate some favorable effects.

Effects of Ten Different Exercise Interventions on Motor Function in Parkinson’s Disease Patients—A Network Meta-Analysis of Randomized Controlled Trials

Objective: The aim of this study was to evaluate ten exercise interventions (YOGA: yoga training, RT: resistance training, AQU: aquatic training, TAI: Taiji Qigong training, TRD: treadmill training, VR: virtual reality training, DANCE: musical dance training, WKT: walking training, CYC: cycling training, BDJ: Baduanjin Qigong training) on motor function in Parkinson’s disease (PD) patients. Design: Through searching PubMed, Embase, Cochrane Library, Web of Science, and CNKI, only randomized controlled trials (RCTs) were collected to study the effects of the ten exercise interventions on motor function in patients with Parkinson’s disease. The included studies were evaluated for methodological quality by the Cochrane bias risk assessment tool. Results: The RCTs were collected between the earliest available date and April 2022. Sixty RCTs were included and the total sample size used in the study was 2859. The results of the network meta-analysis showed that DANCE can significantly improve patients’ Berg Balance Scale (BBS) (SUCRA = 78.4%); DANCE can significantly decline patients’ Unified Parkinson’s Disease Rating Scale score (UPDRS) (SUCRA = 72.3%) and YOGA can significantly decline patients’ Timed-Up-and-Go score (TUGT) (SUCRA = 78.0%). Conclusion: Based on the network meta-analysis and SUCRA ranking, we can state that dance, yoga, virtual reality training and resistance training offers better advantages than other exercise interventions for patients’ motor function.

What web-based information is available for people with Parkinson's disease interested in aquatic physiotherapy? A social listening study

Background

Aquatic physiotherapy is becoming a more frequently utilised treatment for people with Parkinson’s Disease (PD). Consumers are increasingly accessing information regarding health choices online, and it is not known what type or quality of information regarding aquatic physiotherapy is available.

Methods

Web-based platforms (Facebook™, Twitter™, YouTube™, Instagram™, blogs and the web) were searched using the Awario© social listening software. Webpages had to be in English, mention PD, aquatic physiotherapy and its effects. Quality of webpages was assessed using a modified DISCERN tool and content analysis summarised reported effects.

Results

Awario© identified 2992 entries, with 133 assessed using the modified DISCERN tool. A small number (n = 31, 24%) described the effects of aquatic physiotherapy for people with PD. Quality of webpages was low, with many lacking information regarding clear sources of information, contraindications to aquatic physiotherapy and descriptions of the therapeutic environment. Content analysis showed several themes; general physical, PD-specific and psychosocial effects. More than a third of webpages indicated that aquatic physiotherapy would improve strength, balance, pain and aid relaxation. A large number (n = 96, 72%) described at least one hydrodynamic or hydrostatic property of water, most commonly buoyancy (n-83, 62%).

Conclusions

Overall quality of information was poor, and it is recommended that webpages list all potential contraindications to aquatic physiotherapy and direct consumers to discuss potential participation with their healthcare professionals. Webpages also should include information regarding the therapeutic environment, disclose sources of information and focus on enablers to exercise to improve engagement of people with PD in aquatic physiotherapy.

Evidence-Based Aquatic Therapy Guidelines for Parkinson's Disease: An International Consensus Study

BACKGROUND

Aquatic therapy is one therapy option for people living with Parkinson's disease (PD). However, the optimal prescription, dosage, and delivery remain unclear.

OBJECTIVE

i) To generate consensus statements, ii) to establish evidence-based clinical practice aquatic therapy guidelines for PD.

METHODS

Seventy-three international experts were invited to participate in a 3-step modified Delphi study. Gaps in the aquatic therapy evidence, patient preferences, and stakeholder engagement were considered when developing the initial list of 43-statements identified by the research development group. Practice experts rated each statement on an 11-point Likert scale. Consensus for inclusion was set at a priori of ≥70% of respondents scoring an item ≥7. Two rounds of Delphi questionnaires were completed online, and the expert comments were analyzed using content analysis. An online consensus meeting with an expert subgroup (n = 10) then advised on the guideline's acceptability and debated items until consensus for inclusion was reached.

RESULTS

Fifty experts participated in the Delphi round one (83% response rate) and 45 in round two (90% response rate), representing 15 countries. In round one, 35 statements met the criteria for consensus. Content analysis informed the revised statements in round two, where 12 of the remaining 16 statements met consensus. The final agreed aquatic therapy guidelines include key information about dosage, content, safety, contraindications, and the optimal aquatic therapy delivery throughout the disease course.

CONCLUSION

Stakeholders, including international practice experts, informed a rigorous evidence-based approach to integrate the best available evidence, patient preferences, and practice expertise to inform these guidelines.

Physical Therapist Management of Parkinson Disease: A Clinical Practice Guideline From the American Physical Therapy Association

A clinical practice guideline on Parkinson disease was developed by an American Physical Therapy Association volunteer guideline development group that consisted of physical therapists and a neurologist. The guideline was based on systematic reviews of current scientific and clinical information and accepted approaches for management of Parkinson disease. The Spanish version of this clinical practice guideline is available as a supplement (Suppl. Appendix 1).

A Novel Boot Camp Program to Help Guide Personalized Exercise in People with Parkinson Disease

Given the variety of exercise programs available for people with Parkinson's disease (PD), such individuals may struggle to make decisions about what exercise to perform. The objective of this study was to assess the usefulness, satisfaction, and preferences regarding participation in a PD-personalized educational and exercise boot camp program. Attendees participated in a four-day program consisting of exercise sessions, workshops, and social activities. We collected demographic and clinical information. We assessed satisfaction and preferences immediately after. At one-month follow-up, participants assessed usefulness and changes in exercise habits. Eight individuals diagnosed with PD, with a mean age of 59.5 ± 6.8 years, participated. All participants felt "very satisfied" and likely to attend future events. The two favorite sessions were: cognitive stepping and dance-based movements. At one-month follow-up, participants considered the program "very useful" and reported changes in their exercise routine. Our results suggest that the boot camp program was considered useful and capable of influencing participants' exercise habits.

Systematic review and meta-analysis of randomised controlled trials on the effects of yoga in people with Parkinson's disease

PURPOSE

Yoga may be a beneficial treatment for people with Parkinson's disease (PD). However, no studies have critically reviewed and meta-analyzed the scientific evidence for yoga's benefits regarding motor and non-motor symptoms. The purpose of this study was to conduct a systematic review and meta-analysis on the effectiveness of yoga as a rehabilitation strategy for PD.

MATERIALS AND METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a literature search was performed using MEDLINE/PubMed, PEDro, SPORTDiscus, and Scopus. Studies addressing any concepts on the impact of yoga intervention on physical and psychological outcomes in people with PD were included.

RESULTS

Fourteen RCTs were selected, with heterogeneous protocols and outcomes measures. Yoga interventions were safe and well-accepted for patients with mild to moderate PD. The descriptive analysis indicated that its practice might provide both physical and psychological benefits. Preliminary evidence showed that yoga has comparable or superior efficacy to exercise. A subsequent meta-analysis on five RCTs detected that yoga was more effective than passive control in ameliorating motor symptoms.

CONCLUSIONS

Yoga appears to be a promising rehabilitative therapy for individuals with PD. Recommendations are proposed for future studies.IMPLICATIONS FOR REHABILITATIONYoga is a safe and feasible therapy for people with mild to moderate PD.Yoga practice positively impacts physical and mental health in this population.When compared to exercise, yoga showed to have similar or even greater effects.

Is Aquatic Therapy Optimally Prescribed for Parkinson's Disease? A Systematic Review and Meta-Analysis

BACKGROUND

Aquatic therapy offers an alternative physiotherapy approach to managing the motor and non-motor symptoms associated with Parkinson's disease (PD).

OBJECTIVE

This review examined exercise prescription for aquatic therapy in PD and evaluated if aquatic therapy is as effective as land-based physiotherapy for improving movement, disability and wellbeing in people living with PD.

METHODS

A systematic search of eight databases was conducted to identify suitable randomized controlled trials from inception until August 2019. Aquatic therapy prescription data and outcomes of interest included gait, balance, motor disability, mobility, falls, mood, cognitive function and health related quality of life data was extracted and synthesised. A meta-analysis was performed where appropriate.

RESULTS

Fourteen studies involving 472 participants (Hoehn & Yahr scale I-IV) met the inclusion criteria. Eight were of modest quality, scoring 70-80% on the PEDro scale. Seven studies were included in the meta-analysis. Exercise prescription was highly variable and often insufficiently dosed. Similar gains were shown for aquatic therapy and land exercises for balance, motor disability or quality of life. A statistically significant difference was found for mobility as measured using the TUG (-1.5 s, 95 % CI -2.68 to -0.32; p = 0.01, I2 = 13%), in favor of aquatic therapy.

CONCLUSION

Aquatic therapy had positive outcomes for gait, balance and mobility that were comparable to land-based physiotherapy in the early stages of PD. The optimal dosage, content and duration of aquatic interventions for PD could not be confirmed in this meta-analysis. Many trials appeared to be under-dosed and therapy duration was low, ranging from 3-11 weeks.

Community aquatic therapy for Parkinson's disease: an international qualitative study

PURPOSE

To explore the opinions of people living with Parkinson's disease about access to and participation in community aquatic therapy.

METHODS

Focus groups and individual interviews were conducted with people living with Parkinson's disease in Ireland (n = 24) and Australia (n = 10). All discussions were audio-recorded, transcribed verbatim, and thematically analysed.

RESULTS

Four main themes were identified. Primarily, participants were optimistic about their reasons for choosing aquatic therapy and found it beneficial to their health and well-being. Optimal components of aquatic therapy identified were access to individually tailored aquatic programs, completed as a minimum once a week, at a moderate to high-intensity level, and guided by a credentialed instructor. Fear was a significant barrier for a small proportion of participants and was linked to water competence, past experiences, and fall risk associated with the aquatic environment. Participants identified a strong need for education and increased awareness about aquatic therapy benefits to promote greater engagement.

CONCLUSION

Aquatic therapy is a popular exercise choice for people with Parkinson's disease, especially in the early to middle disease stages. Considering the views of people living with Parkinson's disease can aid the design and implementation of interventions and future aquatic research internationally.Implications for RehabilitationAquatic therapy is emerging as an effective physiotherapy approach for managing motor and non-motor symptoms in Parkinson's disease.Little is known regarding community-based aquatic therapy programs from the perspectives of people living with Parkinson's disease internationally.People with Parkinson's disease may benefit from timely information about the unique benefits, prerequisites, and local aquatic therapy facilities to promote greater uptake of aquatic programs.Tailored aquatic therapy interventions delivered within a group setting by a credentialed healthcare professional may increase long-term adherence.

Task-oriented circuit training combined with aerobic training improves motor performance and balance in people with Parkinson's Disease

Goal-based training such as task practice combined with aerobic training (AT) has been suggested to improve motor performance and neuroplasticity for people with Parkinson's Disease (PwPD); however, its effect on clinical outcomes is unclear. Therefore, the main aim was to investigate the effects of task-oriented circuit training combined with AT (TOCT-AT) on balance and gait in PwPD. The secondary aim was to investigate the effects of TOCT-AT on functional mobility, balance confidence, disease severity, and quality of life. Twenty-six PwPD were randomly assigned to either to the experimental group (n = 14) or the control group (n = 12). The control group received AT, while the experimental group received TOCT-AT three times a week for 8 weeks. The main outcomes were the Berg Balance Scale (BBS), Postural Stability Test (PST), Limits of Stability Test (LOS), Pull Test (PT), Six Minute Walk Test (6MWT), Timed Up and Go Test (TUG), Activities-specific Balance Confidence Scale (ABC), Unified Parkinson's Disease Rating Scale (UPDRS), and eight-item Parkinson's Disease Questionnaire (PDQ-8) were secondary outcomes. After intervention, between-group comparisons showed that the experimental group significantly improved more than the control group in all outcomes (p < 0.05). Additionally, both groups significantly improved in BBS, 6MWT, TUG, ABC, UPDRS-II, UPDRS-III, UPDRS total, and PDQ-8 (p < 0.05), while only the experimental group significantly improved in PST, LOS, and PT (p < 0.001). This study suggest that TOCT-AT could improve balance and gait performance, which could also be positively translated into functional mobility, balance confidence, disease severity, and quality of life in PwPD.

Implementation of high-cadence cycling for Parkinson's disease in the community setting: A pragmatic feasibility study

BACKGROUND

Efficacy of exercise to improve motor symptoms in Parkinson's Disease (PD) has been established in multiple clinical trials. The Pedaling for Parkinson's ™ (PFP) program is an existing community-based cycling intervention for individuals with PD. Although PFP program design was informed by in-laboratory efficacy studies, the implementation and effectiveness of the program in the community have not been studied. This feasibility study explores implementation and effectiveness of PFP utilizing the RE-AIM implementation evaluation framework.

METHODS

This was a pragmatic open-label multi-site study. First, community-based gyms were recruited to implement the PFP protocol with enhanced multi-modal training and support. Second individuals with Hoehn and Yahr stage I-III idiopathic PD were recruited to participate. Reach, effectiveness (both clinical scores and participant enjoyment), adoption, implementation (gym and participant fidelity, cost), and maintenance (sustainability) were assessed. Tracking of adverse events was used to monitor safety of the intervention.

RESULTS

Reach was moderate: 59% of participants who expressed interest opted to participate. No effectiveness outcomes demonstrated a significant change from pre to post; however, the program was highly enjoyable (96% of participants who started classes enjoyed the program and 87% wished to continue). Adoption was poor with only four out of 34 gyms participating. The program had poor gym and moderate participant fidelity. The program was maintained for at least 4 months across all sites. The program was implemented safely.

CONCLUSION

Barriers to implementation of nonpharmacologic interventions such as exercise protocols limit reach and availability of these interventions to patients. Pilot studies are needed to inform and direct further implementation efforts. Our pilot study suggests the PFP cycling intervention should be modified prior to attempts at widespread implementation. Modifications made by gyms in this study suggest adaptations to the protocol that may increase fidelity and effectiveness.

Parkinson's disease and virtual reality rehabilitation: cognitive reserve influences the walking and balance outcome

INTRODUCTION

Parkinson's disease (PD) is a neurodegenerative pathology characterized by motor and non-motor symptoms that often lead to several impairments. Many studies show the efficacy of different rehabilitation protocols aimed to improve balance and gait functions in PD patients. However, multiple factors may influence rehabilitation outcome. Recently, it has been observed as the cognitive reserve (CR) may influence the rehabilitation outcome, helping to address the patient toward technological or conventional rehabilitation. Our study investigated how CR may affect motor rehabilitation outcomes in PD patients who undergo virtual reality (VR) rehabilitation, aimed at improving walking and balance.

MATERIALS AND METHODS

Thirty patients affected by idiopathic PD were enrolled. Patients underwent 12 sessions VR training, over 6 weeks (45 min). Six-Minute Walk Test (6MWT) and Berg Balance Scale (BBS) were used to assess walking and balance, respectively. CR was assessed by Cognitive Reserve Index questionnaire (CRIq).

RESULTS

Significant correlations between CR and change from baseline in walking and balance measures were found, with a significant positive correlation between CRIq and 6MWT (r=0.50, p=0.01) and between CRIq and BBS (r=0.41, p=0.04).

DISCUSSION

Our results showed that PD patients with higher CR treated with VR improved significantly more in their balance and walking distance than those with lower CR. The current study suggests that VR when aimed to improve balance and walking in PD patients is more effective in patients with higher CR.

Effect of aquatic exercise on physical function and QOL in individuals with neurological disorder: A systematic review and meta-analysis

BACKGROUND

When applying aquatic exercise program to patients with neurological disorder, quality of life (QOL) can be changed by physical function or psychological improvement.

METHODS

Cochrane Database, CINAHL, Embase, Google Scholar, PEDro, PubMed, ScienceDirect, and SCOPUS were used to systematically search for relevant studies published between January 1999 and June 2019. The study quality was determined using the Physiotherapy Evidence Database (PEDro) scale.

RESULTS

Eight of the 326 retrieved articles met the inclusion criteria. The results of the studies led to a general consensus: physical education program increased balance and gait and decreased pain. QOL improved as physical health, mental health, and vitality recuperated.

CONCLUSIONS

The findings indicate that aquatic exercise program could be helpful when treating neurological disorders and should be considered as a means of reducing pain while increasing physical function and QOL in standard clinical research programs.

Review of Clinical Trials on the Effects of Tai Chi Practice on Primary Hypertension: The Current State of Study Design and Quality Control

The modulation of Tai Chi in physiological function and psychological status attracts sustaining attention. This paper collected original articles regarding the effects of Tai Chi practice on modulating primary hypertension from 7 electronic databases (PubMed, Excerpta Medica Database, Cochrane Library, Web of Science, Chinese Knowledge Resource Integrated Database, Wanfang Database, and China Science and Technology Journal Database) from their dates of origin to October 1st, 2020. A total of 45 articles were included. The literature analyses have shown that the benefits of Tai Chi practice for blood pressure management have been identified in all of the included 45 studies, and Tai Chi exercise has shown significant efficacy in improving hypertension clinical symptoms and quality of life, compared to the majority of control interventions, though there are also some methodological issues, including small sample sizes, lack of exact randomization methods and quality control criteria, and lack of specific standards used to measure the characteristics of Tai Chi practice. In the future, the inclusion of additional design standards, stricter quality controls, and evaluation measures for the features of Tai Chi practice is required in trials evaluating its effects on hypertension.

Complementary Therapies in Parkinson Disease: a Review of Acupuncture, Tai Chi, Qi Gong, Yoga, and Cannabis

Parkinson disease (PD) is a progressive neurodegenerative condition characterized by bradykinesia, rigidity, resting tremor, and postural instability. Non-motor symptoms, including pain, fatigue, insomnia, anxiety, and depression to name a few, are increasingly recognized and often just as disabling at motor symptoms. The mainstay of treatment is dopamine replacement; however, the beneficial effects tend to wane over time with disease progression, and patients often experience motor fluctuations and medication side effects. The lack of a disease-modifying intervention and the shortcomings of traditional symptomatic medications have led many patients to pursue complementary therapies to alleviate motor and non-motor symptoms associated with PD. The term complementary implies that the therapy is used along with conventional medicine and may include supplements, manipulative treatments (chiropractic, massage), exercise-based programs, and mind-body practices. As these practices become more widespread in Western medicine, there is a growing interest in evaluating their effects on a number of medical conditions, PD included. In this review, we provide an update on clinical trials that have evaluated the effectiveness of complementary treatments for patients with PD, specifically focusing on acupuncture, Tai Chi, Qi Gong, yoga, and cannabis.

Effects of water-based exercise on functioning and quality of life in people with Parkinson's disease: a systematic review and meta-analysis

AIM

To investigate the effects of the water-based exercise on balance, mobility, mobility and functional independence, functional performance, fear of falling and quality of life in people with Parkinson's disease.

METHODS

We searched pubmed/MEDLINE, Cochrane Central Register of Controlled Trials, PEDro data base and SciELO to June 2020 for randomised controlled trials that investigated the effects of water-based exercise in people with Parkinson's disease. Two comparisons were made: water-based exercise versus usual care and water-based exercise versus land-exercise. The main outcomes were Balance, Confidence, Mobility, Unified Parkinson's Disease Rating Scale and quality of life. Mean differences (MD) with 95% confidence interval (CI) were calculated, and heterogeneity was assessed using the I² test.

RESULTS

Fifteen randomised controlled trials were found (435 people). Compared to usual care, water-based exercise resulted in improvement in balance MD (9.1, 95% CI: 6.5, 11.8, N = 45). Water-based exercise resulted in improvement in balance MD (3.1, 95% CI: 1.2, 5.0, N = 179), mobility MD (-2.2, 95% CI: -3.3, -1.0, N = 197) and quality of life MD (-5.5, 95% CI: -11, -0.07, N = 98) compared to land-based exercise, but without significant difference in functional performance MD (0.01, 95% CI: -2.6 to 2.7, N = 69). Land-based exercise resulted in improvement in fear of falling MD (-3.5, 95% CI: -5.6, -1.3, N = 58) compared to water-based exercise.

CONCLUSION

Water-based exercise was more efficient than land-based exercise and/or usual care in improving balance, mobility and quality of life in people with Parkinson's disease.

Aquatic Therapy in Contemporary Neurorehabilitation: An Update

Aquatic therapy has been used extensively in a number of neurologic diseases and pathologies. This review describes disease-specific rehabilitative applications for this population. Recent research has offered scientific support for use in common neurological diseases that are part of rehabilitative practice, and very recent findings may create even firmer support for its use in these as well as other conditions. Stroke, Parkinsonism, and multiple sclerosis are areas that have recently received a significant number of published studies. Dementia is another area that has been more recently studied and received basic science support. Cerebral palsy has also had recent supportive evidence published. Available literature is reviewed to create a more evidence-based support for the use of aquatic therapy in neurorehabilitation.

Implementation of a Community-Based Exercise Program for Parkinson Patients: Using Boxing as an Example

BACKGROUND

Persons with Parkinson's disease (PD) benefit from continuous exercise through participation in community-based exercise programs. However, community programs often lack PD-specific knowledge needed to provide safe and adequately dosed exercise.

OBJECTIVE

To evaluate the acceptability and safety of a PD-specific boxing program in the community.

METHODS

We developed specific educational resources to facilitate the boxing instructors. We also organized an educational and practical workshop for patients (n = 26) and instructors (n = 10), and assessed: (a) participants' satisfaction; (b) instructors' appreciation of the educational resources; and (c) numbers of patients interested in participating in the boxing program. After 18 months, patients and instructors completed a questionnaire evaluating: (a) participants' satisfaction; (b) adverse events; (c) facilitators and barriers; and (d) proportion of participants at follow-up.

RESULTS

Twenty-six persons with PD (62% men) and 10 boxing instructors participated in the workshop. 81% of patients and 80% of instructors were very satisfied. Instructors found the educational materials "very helpful" (60%) or "helpful" (40%). Patients expressed a clear interest (54%) or possible interest (46%) in the program. We initiated classes with 10 participants. At 18-months follow-up, the program consisted of four boxing sessions/week, led by three instructors, with 40 participants. Seventeen patients responded to the questionnaire at follow-up. Participants were "very satisfied" (53%), "satisfied" (35%) and neither satisfied nor unsatisfied (12%) with the program. Adverse effects were mild (e.g., muscle aches). Transportation and physical disability were the main barriers for participation.

CONCLUSIONS

The boxing program was well-received, with increasing numbers of participants at 18 months. The educational resources can support boxing instructors participating in current and future boxing classes being delivered in the community.

Effects of Simulated Horseback Riding on Balance, Postural Sway, and Quality of Life in Older Adults With Parkinson's Disease

The purpose of this study was to determine changes in balance, postural sway, and quality of life after 6 wk of simulated horseback riding in adults diagnosed with Parkinson's disease. Eight older adults completed two 60-min riding sessions weekly for 6 wk. Variables of balance, postural sway, and quality of life were measured 6 wks before and within 1 wk before and after the intervention. Berg Balance Scale scores decreased from baseline to preintervention (48.36 ± 5.97 vs. 45.86 ± 6.42, p = .050) and increased from preintervention to postintervention (45.86 ± 6.42 vs. 50.00 ± 4.38, p = .002). Cognitive impairment, a dimension of quality of life, improved from baseline to postintervention (37.5 ± 20.5 vs. 21.5 ± 14.4, p = .007). Six weeks of simulated horseback riding may improve balance and cognitive impairment in older adults with Parkinson's disease.

Treatment options for postural instability and gait difficulties in Parkinson's disease

Introduction: Gait and balance disorders in Parkinson's disease (PD) represent a major therapeutic challenge as frequent falls and freezing of gait impair quality of life and predict mortality. Limited dopaminergic therapy responses implicate non-dopaminergic mechanisms calling for alternative therapies.Areas covered: The authors provide a review that encompasses pathophysiological changes involved in axial motor impairments in PD, pharmacological approaches, exercise, and physical therapy, improving physical activity levels, invasive and non-invasive neurostimulation, cueing interventions and wearable technology, and cognitive interventions.Expert opinion: There are many promising therapies available that, to a variable degree, affect gait and balance disorders in PD. However, not one therapy is the 'silver bullet' that provides full relief and ultimately meaningfully improves the patient's quality of life. Sedentariness, apathy, and emergence of frailty in advancing PD, especially in the setting of medical comorbidities, are perhaps the biggest threats to experience sustained benefits with any of the available therapeutic options and therefore need to be aggressively treated as early as possible. Multimodal or combination therapies may provide complementary benefits to manage axial motor features in PD, but selection of treatment modalities should be tailored to the individual patient's needs.

Aquatic exercise improves motor impairments in people with Parkinson's disease, with similar or greater benefits than land-based exercise: a systematic review

QUESTIONS

What are the effects of aquatic exercise on disease severity, (non-)motor impairments, activity performance, fear of falling, and quality of life in people with Parkinson's disease (PD)? Does aquatic exercise have greater effects on these outcomes than other forms of exercise in people with PD?

DESIGN

Systematic review and meta-analysis of randomised controlled trials.

PARTICIPANTS

People with idiopathic PD.

INTERVENTION

Supervised aquatic exercise programs ≥ 2 weeks.

OUTCOMES MEASURES

The primary outcomes were disease severity, motor impairments, activity performance, and fear of falling. The secondary outcomes were non-motor impairments and quality of life.

RESULTS

Of the 129 identified records, seven trials met the inclusion criteria and six were meta-analysed (159 participants). One trial assessed the effect of aquatic exercise compared with control and found a significant improvement in the Unified Parkinson's Disease Rating Scale Part III (MD -4.6, 95% CI -7.5 to -1.7) in favour of aquatic exercise. Six studies compared aquatic exercise with land-based exercise after intervention (mean 7.2 weeks of training (SD 2.2); 159 participants). The effect of aquatic exercise was superior to land-based exercise on the Berg Balance Scale (MD 2.7, 95% CI 1.6 to 3.9), the Falls Efficacy Scale (MD -4.0, 95% CI -6.1 to -1.8) and the 39-item Parkinson's Disease Questionnaire (MD -6.0, 95% CI -11.3 to -0.6), with no other significant effects identified. The significant benefit on the Berg Balance Scale was maintained at the follow-up assessment (MD 6.3, 95% CI 2.1 to 10.5, 54 participants).

CONCLUSION

Aquatic exercise improves motor impairments in people with PD significantly more than no intervention. It also has slightly to moderately greater benefits than land-based exercise on balance capacity, fear of falling, and health-related quality of life. On other outcomes, the benefits of aquatic exercise are similar to those of land-based exercise.

Controversial Impact of Sirtuins in Chronic Non-Transmissible Diseases and Rehabilitation Medicine

A large body of evidence reports about the positive effects of physical activity in pathophysiological conditions associated with aging. Physical exercise, alone or in combination with other medical therapies, unquestionably causes reduction of symptoms in chronic non-transmissible diseases often leading to significant amelioration or complete healing. The molecular basis of this exciting outcome—however, remain largely obscure. Epigenetics, exploring at the interface between environmental signals and the remodeling of chromatin structure, promises to shed light on this intriguing matter possibly contributing to the identification of novel therapeutic targets. In this review, we shall focalize on the role of sirtuins (Sirts) a class III histone deacetylases (HDACs), which function has been frequently associated, often with a controversial role, to the pathogenesis of aging-associated pathophysiological conditions, including cancer, cardiovascular, muscular, neurodegenerative, bones and respiratory diseases. Numerous studies, in fact, demonstrate that Sirt-dependent pathways are activated upon physical and cognitive exercises linking mitochondrial function, DNA structure remodeling and gene expression regulation to designed medical therapies leading to tangible beneficial outcomes. However, in similar conditions, other studies assign to sirtuins a negative pathophysiological role. In spite of this controversial effect, it is doubtless that studying sirtuins in chronic diseases might lead to an unprecedented improvement of life quality in the elderly.

The Role of Rehabilitation in Patients With Progressive Supranuclear Palsy: A Narrative Review

Progressive supranuclear palsy (PSP) is a progressive neurodegenerative disorder caused by the deposition of abnormal proteins in neurons of the basal ganglia that limit motor ability, resulting in disability and reduced quality of life. So far, no pharmacologic therapy has been developed, and the treatment remains symptomatic. The aim of the present study is to perform a systematic investigation of the literature, and to determine the types and effects of rehabilitative interventions used for PSP. A search of all studies was conducted in MEDLINE/PubMed, the Cochrane Central Register of Controlled Trials, CINAHL, and EMBASE. Twelve studies were identified, including 6 case reports, 3 case series, one case-control study, one quasi-randomized trial (i.e. not truly random) with crossover design, and one randomized controlled trial, with 88 patients investigated overall. Rehabilitative interventions varied in type, number, frequency, and duration of sessions. The most commonly used clinical measures were the Progressive Supranuclear Palsy Rating Scale (PSPRS) and Unified Parkinson's Disease Rating Scale (UPDRS). Physical exercises were the main rehabilitative strategy but were associated with other interventions and rehabilitative devices, in particular treadmill and robot-assisted gait training. All studies showed an improvement in balance and gait impairment with a reduction of falls after rehabilitation treatment. Because of poor methodological quality and the variety of rehabilitative approaches including different and variable strategies, there was insufficient evidence of the effectiveness of any specific rehabilitation intervention in PSP. Despite this finding, rehabilitation might improve balance and gait, thereby reducing falls in PSP patients.

Complementary and Alternative Medicine and Exercise in Nonmotor Symptoms of Parkinson's Disease

The use of complementary and alternative medicine (CAM) therapy in nonmotor symptoms (NMS) for Parkinson disease (PD) is growing worldwide. Well-performed, systematic evidence-based research is largely lacking in this area and many studies include various forms of CAM with small patient numbers and a lack of standardization of the approaches studied. Taichi, Qigong, dance, yoga, mindfulness, acupuncture, and other CAM therapies are reviewed and there is some evidence for the following: Taichi in sleep and PDQ39; dance in cognition, apathy, and a mild trend to improved fatigue; yoga in PDQ39; and acupuncture in depression, PDQ39, and sleep. Exercise including occupational therapy (OT) and physical therapy (PT) has been studied in motor symptoms of PD and balance but only with small studies with a mounting evidence base for use of exercise in NMS of PD including PDQ39, sleep, fatigue, depression, and some subsets of cognition. Studies of OT and PT largely show some benefit to depression, apathy, and anxiety. Sustainability of an improvement has not been shown given short duration of follow up. Finding optimal control groups and blind for these interventions is also an issue. This is a very important area of study since patients want to be self-empowered and they want guidance on which form of exercise is the best. Additionally, evidence for PT and OT in NMS would give added weight to get these interventions covered through medical insurance.
