The effect of Tai Chi lower extremity exercise on the balance control of older adults in assistant living communities

BACKGROUND

Although Tai Chi (TC) is an evidence-based fall prevention training for older adults, its effective movements remain unclear, which may limit the practice of TC. The purpose of this study was to compare the effectiveness of TC lower extremity exercise (TC LEE), the 8-form Tai Chi (8-form TC), and a stretching control intervention for improving balance and functional mobility among older adults.

METHODS

This was a randomized controlled trial. A total of 102 participants (79 ± 6 years old) were recruited from assisted living facilities. All participants were randomly assigned to the TC LEE (n = 40), 8-form TC (n = 31), and stretching (n = 31) groups in which they received the respective interventions for 16 weeks. The Berg Balance Scale (BBS), Timed Up and Go (TUG) test, and center of pressure (COP) measurements during quiet stance were collected prior to and following the 16-week interventions. Comparisons on all measurements were conducted among all groups.

RESULTS

Significant improvements were found in BBS (P = 0.002), TUG test (P = 0.001), root mean square amplitude of COP displacement in the anterior-posterior (P = 0.001) and medial-lateral (P = 0.001) directions, and average COP speed in the anterior-posterior (P = 0.001) and medial-lateral (P = 0.001) directions after training in the TC intervention groups compared with the stretching group. The upper limit of the 95% confidence interval (CI) of differences in change scores on the BBS (-0.8 - 1.3 points) between the TC LEE group and the 8-form TC group was within equivalence margins (1.8 points), while the upper limit of the 95% CI of differences in change scores on the TUG test (0.1 - 2.1 s) exceeded the equivalence margin (0.7 s) with the TC LEE group having the larger change scores.

CONCLUSION

TC LEE can improve balance and functional mobility in older adults, and may have greater effect than the 8-form TC on improving functional mobility as measured by the TUG test.

Tai Ji on Cognitive Function Improvement in Parkinson's Disease: A Meta-Analysis

BACKGROUND

Tai Ji (TJ) can improve cognitive function, which in turn brings life quality to Parkinson's disease (PD) patients. Cognitive function is thus important for PD patients. Analyzing the cognitive function and obtaining precise TJ exercise prescriptions are effective in treating PD patients.

OBJECTIVES

The purpose of this review was to discuss the current Randomized Controlled Trials (RCTs) of TJ and cognitive function improvement in PD.

MATERIALS AND METHODS

Databases, including PubMed, Web of Science, Scopus, Cochrane Library, EBSCOhost, Wan Fang, and CNKI, were searched. Cochrane systematic evaluation method was adopted wherein 6 RCTs met the final inclusion criteria.

RESULTS

Among the 6 included RCTs, 3 were of high quality, and the rest were of medium quality. Quantitative analysis exhibited that TJ intervention improved the cognitive function of PD patients. TJ promoted the global cognitive function (p < 0.05) and the executive function (p = 0.09) compared with the control. However there was no significant improvement in cognitive motor. TJ training intervention doses of two times a week with 45-60 min sessions over ≤12 weeks could improve the cognitive function of PD patients.

CONCLUSIONS

TJ affects the cognitive function of PD patients. However, this effect may have a reduced or no significant impact as the disease increases. PD patients can choose TJ as an intervention for 45-60 min twice a week for at least 12 weeks to accomplish maximum improvement in cognitive function.

Effects of Tai Chi on Postural Control in People with Peripheral Neuropathy: A Systematic Review with Meta-Analysis

BACKGROUND

Effects of Tai Chi on people with peripheral neuropathy (PN) are not yet apparent. This systematic review was conducted to evaluate the effects of Tai Chi on postural control in people with PN.

METHODS

Literature was screened in seven databases for relevant randomized controlled trials. The reports and methodological quality were evaluated. A meta-analysis was performed using RevMan5.4 software.

RESULTS

Ten reports were included, involving a total of 344 subjects. The meta-analysis found that Tai Chi therapy for people with PN resulted in a smaller sway area, in the double-leg stance with eyes closed test (SMD = -2.43, I² = 0%), than that observed in the control group, greater distance covered in the six-minute walking test (SMD = -0.46, I² = 49%) and faster performance in the timed-up-and-go test (SMD = 0.68, I² = 50%), than the baseline.

CONCLUSIONS

Tai chi effectively enhanced dynamic postural control in people with PN. However, no better effects on postural control from Tai Chi than from other rehabilitation approaches were observed in this study. Further high-quality trials are needed to better understand Tai Chi's effects on individuals with PN.

Effects of Tai Chi Yunshou on upper-limb function and balance in stroke survivors: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

Physical rehabilitation plays an important role in the recovery of motor function after a stroke. This study aimed to evaluate the effects of Tai Chi Yunshou (TCY), a form of physical therapy, on upper-limb function and balance in stroke survivors.

METHODS

MEDLINE, Embase, CENTRAL and five Chinese databases were retrieved from inception to July 1, 2020 (updated on March 31, 2022). Randomized controlled trials of TCY versus no-treatment for stroke were included. The RoB-2 was used to evaluate the quality of included studies. Upper-limb motor impairment, balance, and activities of daily living (ADLs) were measured by Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE), Berg Balance Scale (BBS), and Barthel Index (BI), respectively. Data synthesis was performed using RevMan (v5.3), and expressed as mean difference (MD) with 95% confidence intervals (CI).

RESULTS

Seven studies with 529 participants were included. Compared with no-treatment, TCY improved FMA-UE (MD = 7.31, 95% CI: 5.86-8.77, minimal clinically important difference [MCID]: 9-10), BBS (MD = 4.68, 95% CI: 0.28-9.07, MCID: 4), and BI (MD = 4.12, 95% CI: 3.28-4.96, MCID: 1.85) in stroke survivors.

CONCLUSION

TCY may benefit balance and ADLs in rehabilitation after a stroke, but it may not improve upper-limb function clinically.

Tai Chi for spatiotemporal gait features and dynamic balancing capacity in elderly female patients with non-specific low back pain: A six-week randomized controlled trial

BACKGROUND

Non-specific low back pain (NS-LBP) is a serious public health problem. Tai Chi is promising in reducing the risk of falls and alleviating symptoms in this population.

OBJECTIVE

To investigate the effect of Tai Chi on gait and dynamic balance in elderly women with NS-LBP.

METHODS

20 women (age > 65 yr.) with NS-LBP were randomly assigned to a Tai Chi group (n= 10) or a control group (n= 10). The Tai Chi group practiced Tai Chi exercise 3 times a week for 6 weeks. Each session lasted 60 minutes. Pain, spatiotemporal gait features and dynamic balancing capacity were assessed at 0 and 6 weeks.

RESULTS

Compared to the control group at 6 weeks, the Tai Chi group had a significant decrease in VAS (p= 0.027) and stride width (p= 0.019), significant improvement in gait velocity, stride length (p< 0.001). Regarding dynamic balance capacity, the Tai Chi group had significant improvements in anterior (Left: p= 0.001; Right: p= 0.038), postero-lateral (Left: p< 0.001; Right: p= 0.038), and postero-medial (Left: p= 0.015; Right: p= 0.018).

CONCLUSION

6-week Tai Chi can relieve pain and improve gait and dynamic balance in elderly women with NS-LBP, which suggests Tai Chi could be a promising rehabilitation intervention to reduce the risk of falls in this population.

Virtual Tai Chi program for patients with irritable bowel syndrome with constipation: Proof-of-concept feasibility trial

BACKGROUND

Satisfaction with current treatment options for irritable bowel syndrome with constipation (IBS-C) is low, with many patients turning to complementary treatments. Tai Chi is a mind-body medicine practice with proven efficacy in other functional disorders. As a proof-of-concept, we tested the feasibility and preliminary clinical outcomes associated with a Tai Chi program designed for IBS-C.

METHODS

A total of 27 IBS-C patients participated in a single-arm trial of 8 sessions of Tai Chi delivered weekly over 7 weeks via live videoconferencing in group format. Clinical improvement was assessed via change in IBS Symptom Severity Score (IBS-SSS) from baseline to 4 weeks posttreatment (week 11) with secondary outcomes exploring symptom ratings, IBS-related quality of life (IBS-QOL), GI-specific anxiety, abdominal distention, and psychological factors.

KEY RESULTS

Despite substantial dropout (n = 7; 26%), the treatment protocol had moderate to excellent feasibility for other criteria. Treatment satisfaction was excellent. Exit interviews confirmed high satisfaction with the program among completers, but a high burden of data collection was noted. One participant experienced an adverse event (mild, exacerbation of sciatica). There was a significant improvement in intra-individual IBS-SSS between baseline and posttreatment (average change -66.5, 95% CI -118.6 to -14.3, p = 0.01). Secondary outcomes were notable for improvements in other IBS symptom scoring measures, IBS-QOL, measured abdominal diameter, and leg strength.

CONCLUSIONS AND INFERENCES

Our data provide preliminary evidence of the feasibility of a Tai Chi intervention for IBS-C, show promise for improving outcomes, and identify more streamlined data collection as an area for further program improvement.

Concepts and Application of Tai Ji in Stroke Rehabilitation: A Narrative Review

Stroke remains a leading cause of adult disability, and it decreases the health-related quality of life due to functional disability and poor functional recovery in stroke. Tai Ji has been recently introduced to overcome disabilities. This review aims to explain the effects of Tai Ji on functional recovery in stroke patients, linking it to current approaches, concepts and therapies such as Bobath and proprioceptive neuromuscular facilitation techniques. A compilation of recent literature on Tai Ji's use in stroke rehabilitation from Google scholar and PubMed Central (2018 to 2022). The benefits of Tai Ji in stroke functional recovery were studied and explained based on its similarity in concepts to current conventional stroke rehabilitation approaches. There were few randomized controlled trials on Tai Ji in functional recovery among stroke patients. However, all literature identified Tai Ji as beneficial in stroke rehabilitation. However, there was no literature on explaining the Tai Ji movement based on current conventional stroke rehabilitation approaches. Tai Ji carries similar theories to the current neurorehabilitation approach. Tai Ji can be modified and incorporated into stroke rehabilitation programs based on patients' needs to produce promising outcomes.

Tai chi as an adjunctive therapy for individuals who plateau after vestibular rehabilitation

OBJECTIVE

This study aimed to evaluate the effectiveness of tai chi on balance in patients with improved but persistent dizziness and imbalance following completion of traditional vestibular rehabilitation therapy.

METHOD

Patients who completed vestibular rehabilitation therapy with persistent imbalance were prospectively enrolled in a tai chi programme comprising eight weekly classes. Balance was assessed before the first and after the eighth session using the Dynamic Gait Index, Activities-Specific Balance Confidence scale and Dizziness Handicap Inventory.

RESULTS

A total of 37 participants (34 females, 3 males) completed the programme with balance testing. Mean age was 76.8 years (range, 56-91 years). Mean Dynamic Gait Index significantly increased after completion of tai chi (p < 0.00001). Mean Activities-Specific Balance Confidence scale score increased from 63.6 to 67.9 per cent (p = 0.046). A subset (n = 18) of patients completed a Dizziness Handicap Inventory without significant post-therapeutic change (p = 0.62). Most (36 of 37; 97.3 per cent) patients demonstrated post-therapy improvement on one or more assessments.

CONCLUSION

Tai chi is a viable adjunct to improve balance in patients who complete a vestibular rehabilitation therapy programme.

The effects of sitting Tai Chi on physical and psychosocial health outcomes among individuals with impaired physical mobility: A systematic review and meta-analysis

BACKGROUND

Impaired physical mobility refers to a limitation in independent and purposeful physical movement of the body or one or more extremities. Physical restrictions result in negative consequences on an individual's physical and psychosocial functions. Sitting Tai Chi, a derivative form of traditional Tai Chi, has been found to increase the flexibility of all joints involved and enhance the ability to perform physical activity. However, the evidence of sitting Tai Chi on physical and psychosocial health outcomes on individuals with impaired physical mobility is limited.

OBJECTIVES

To critically synthesize evidence that evaluates the effects of sitting Tai Chi on health outcomes among individuals with impaired physical mobility and to identify implementation strategies for the sitting Tai Chi intervention.

METHODS

Searches were performed across 11 English and two Chinese databases systematically from inception to January 2020. Randomised controlled trials and non-randomised controlled trials, written in English or Chinese were included. Two independent reviewers screened all eligible studies, appraised risk of bias, and extracted the data. Meta-analyses were conducted using Review Manager 5.4 and narrative syntheses were performed where meta-analysis was inappropriate. The certainty of evidence was assessed using Grades of Recommendation, Assessment, Development and Evaluation profiler Guideline Development Tool. This study was registered in PROSPERO.

RESULTS

A total of 1,446 records were generated and 11 studies were eligible for inclusion. Meta-analysis reported a statistically significant effect size favouring sitting Tai Chi on depressive symptoms (SMD: -1.53, 95% CI: -2.81 to -0.21, 2 studies; very low quality), heart rate (MD: -5.72, 95% CI: -11.16 to -0.29, 2 studies; low quality) and social domain of quality of life (MD: 1.42, 95% CI: 0.66 to 2.19, 3 studies; low quality).

CONCLUSIONS

Sitting Tai Chi was found to have favourable effects on depressive symptoms, heart rate, and social domain of quality of life of individuals with impaired physical mobility. Very low to low quality evidence does not support the effectiveness of sitting Tai Chi on dynamic sitting balance, handgrip strength, and the physical and psychological domains of quality of life. There was limited evidence to suggest the best implementation strategies for the sitting Tai Chi intervention. It is anticipated that more well-designed studies will continue developing high quality evidence in this field.

Tai Chi Is Safe and Effective for the Hip Joint: A Biomechanical Perspective

There is little research related to the biomechanical effects of Tai Chi on the hip joint. This study was aimed to analyze the biomechanical characteristic of a typical Tai Chi movement, Brush Knee and Twist Step. A total of 12 experienced older men voluntarily participated in this study. Each participant was requested to perform standard Brush Knee and Twist Step and normal walking. The scaled-generic musculoskeletal model of each participant was developed. A finite element model of the hip joint and pelvis was established and validated. Data from each trail were input to the model for simulation, and the biomechanics were compared between Brush Knee and Twist Step and walking. Compared with walking, Tai Chi may have better improvement in the range of motion of the hip joint and the coordination of the neuromuscular system under safer condition. It is suitable for patients with hip osteoarthritis and the older adults with severe muscle loss, and clinical studies are required to confirm it further.

Effectiveness of Tai Chi for health promotion for adults with health conditions: a scoping review of Meta-analyses

Purpose: To complete a scoping review of meta-analyses summarizing evidence of the effectiveness of Tai Chi for adults with health conditions.Materials and Methods: Meta-analyses were retrieved from Medline, Embase, AMED, CINAHL, SPORTDiscus, PsychINFO, Web of Science, PubMed Health and the Cochrane Library from database inception to early September 2018. Multistage deduplication and screening processes identified full-length, unique, peer-reviewed meta-analyses. Two people independently appraised 42 meta-analyses based on the GRADE system and organized results into 3 appendices subsequently collated into heterogeneous, statistically significant, and statistically insignificant tables.Results: "High" and "moderate" quality evidence indicates that Tai Chi can significantly benefit adults with health conditions including cancers, chronic obstructive pulmonary disease, coronary heart disease, depression, heart failure, hypertension, low back pain, osteoarthritis, osteoporosis, Parkinson's Disease and stroke. Outcomes included significant improvements in activities of daily living, balance, exercise capacity, gait, mastery, mental health, mobility, motor function, participation in daily life, physical function, quality of life, range of motion, and strength; with reductions in blood pressure, body mass index, depression, disability, dyspnea, falls, fatigue, pain, stiffness, and waist circumference.Conclusions: Healthcare providers now have information to advise clients with health conditions on the effectiveness of Tai Chi for overall health promotion.IMPLICATIONS FOR REHABILITATIONTai Chi is a form of safe, enjoyable, light-to-moderate aerobic physical activity for adults that is inexpensive to implement in diverse community settings.Adults with health conditions require physical activity for prevention of secondary impairments and over-all health promotion.This scoping review of meta-analyses elucidates "high" and "moderate" quality evidence of the effectiveness of Tai Chi in improving important outcomes for people with numerous health conditions.This information can be useful for healthcare providers who wish to recommend effective community-based physical activity to clients they are serving.

[The effect of a falls prevention program in elderly people in primary health care. What does Tai Chi practice provide?]

OBJECTIVE

Falls in the elderly are a major health problem. There are multiple experiences of intervention in primary care. Aim: To evaluate the impact of a multifactorial intervention in the prevention of falls in elderly people. To compare the differential effect of the practice of Tai Chi.

METHODS

Non-randomized before-after quasi-experimental design in an urban health center between the years 2014-2017. The study population was those over 65 years old with a high risk of falls. The intervention consisted of an individual assessment of risk factors: sensory problems, balance, orthostatic hypotension, treatments (psychotropic drugs, hypotensive drugs), barriers, technical aids. It was intervened in its correction. Tai Chi group participation is proposed. The dependent variables (baseline and year measurements) were Barthel, Unipodal Station Test (TEU), number of falls per year, Anxiety/Depression Goldberg Scale (EADG), number of medical consultations per year, walking aids, Daily Dose Defined of analgesics (DDD)/ year. The before-after analysis was performed using the Chi2 and T Student statistics for paired samples.

RESULTS

A total of 93 patients participated with an average age of 76+06,65, 84.9% women. Falls/year baseline 1.65 + 0.24; no significant differences between groups with or without Tai Chi in any baseline variable. At one year, average reduction of falls/year 0.53 (IC95% 0,07-0,99) (p=0.023), EADG anxiety 1.4±0.33 points (p<0.0001), EAGD depression 0.73±0.26 points (p=0.007). 44 patients practiced Tai Chi; finding: reduction of 1.88 (IC95% 0.90-2.80) points (p<0.0001) in EADG anxiety and 0.86 points (IC95% 0.12-1.60) (p=0.024) in EADG depression; 30.9% of patients abandoned technical aids (p<0.0001); 11% started psychotropic drugs. 49 patients did not practice Tai Chi; of them: EADG anxiety reduction of 1,020 points (IC95% 0.07-1.96) (p=0.035); 41.2% of patients initiated psychotropic drugs (p=0.001); none of the patients abandoned technical aids and 14.3% started them (p<0.001).

CONCLUSIONS

The intervention reduced the number of falls, anxiety, the use of psychotropic drugs, depression, and the use of walking aids, with differential benefit of Tai Chi in these last three aspects.

Does Tai Chi improve balance and reduce falls incidence in neurological disorders? A systematic review and meta-analysis

OBJECTIVE

To evaluate the effect of Tai Chi on balance and reducing falls incidence in neurological disorders.

DATA SOURCES

AMED, Embase, Web of Science, SCOPUS, EBSCO and Medline from inception until February 2018.

REVIEW METHOD

Randomized controlled trials of Tai Chi compared with active or no treatment control, measuring balance with the Berg Balance Scale or the Timed Up and Go Test and number of falls in neurological disorders were included. Methodological quality was assessed using PEDro and quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system.

RESULTS

A total of 10 studies involving 720 participants were reviewed. Seven studies were in Parkinson's disease and three in stroke. Seven studies were of high methodological quality and three were low. Meta-analyses of balance measured with the Timed Up and Go Test in Parkinson's disease revealed a statistically significant effect of Tai Chi compared to no treatment (weighted mean difference (WMD), -2.13; 95% confidence interval (CI), -3.26 to -1.00; P < 0.001) and was insignificant (WMD, -0.19; 95% CI, -1.74 to 1.35; P = 0.81) when compared with active treatment. Tai Chi significantly reduced falls incidence in Parkinson's disease (odds ratio (OR), 0.47; 95% CI, 0.29 to 0.77; P = 0.003) and stroke (OR, 0.21; 95% CI, 0.09 to 0.48; P < 0.001). Balance measured with the Timed Up and Go Test comparing Tai Chi and active treatment was insignificant (WMD, 0.45; 95% CI, -3.43 to 2.54; P = 0.77) in stroke.

CONCLUSION

Tai Chi is effective in reducing falls incidence in Parkinson's disease and stroke. This systematic review did not find high-quality studies among other neurological disorders.

Mindfulness Is Associated With Treatment Response From Nonpharmacologic Exercise Interventions in Knee Osteoarthritis

OBJECTIVE

To examine the association between baseline mindfulness and response from exercise interventions in knee osteoarthritis (OA).

DESIGN

Cohort study; responder analysis of a clinical trial subset.

SETTING

Urban tertiary care academic hospital.

PARTICIPANTS

Participants with symptomatic, radiographic knee OA (N=86; mean age, 60y; 74% female; 48% white).

INTERVENTIONS

Twelve weeks (twice per week) of Tai Chi or physical therapy exercise.

MAIN OUTCOME MEASURES

Treatment response was defined using Osteoarthritis Research Society International criteria indicating meaningful improvements in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain, WOMAC function, or Patient Global Assessment scores. At baseline, participants completed the Five Facet Mindfulness Questionnaire (mean total score, 142±17) and were grouped into 3 categories of total mindfulness: higher, medium, or lower. Relative risk (RR) ratios were used to compare treatment response across groups.

RESULTS

Participants with higher total mindfulness were 38% (95% confidence interval [CI], 1.05-1.83) more likely to meet responder criteria than those with lower mindfulness. We found no significant difference between medium and lower mindfulness groups (RR=1.0; 95% CI, 0.69-1.44). Among the 5 mindfulness facets, medium acting-with-awareness was 46% (95% CI, 1.09-1.96) more likely to respond than lower acting-with-awareness, and higher acting-with-awareness was 34% more likely to respond, but this did not reach significance (95% CI, 0.97-1.86).

CONCLUSIONS

In this study, higher mindfulness, primarily driven by its acting-with-awareness facet, was significantly associated with a greater likelihood of response to nonpharmacologic exercise interventions in knee OA. This suggests that mindfulness-cultivating interventions may increase the likelihood of response from exercise.

The effects of Tai Chi on physical and psychosocial function among persons with multiple sclerosis: A systematic review

OBJECTIVES

Conduct a systematic review to evaluate the effects of Tai Chi on physical and psychosocial function among individuals with Multiple Sclerosis.

METHODS

An electronic literature search of 12 databases using controlled vocabulary function and keywords from inception through August 2016. All Tai Chi intervention studies assessing physical and psychosocial function among persons with Multiple Sclerosis were included. Study quality was scored using an established tool examining 16 study elements (range=0-32).

RESULTS

A total of 91 articles were retrieved, with 3 additional articles identified through reviewing bibliographies of relevant articles. A total of 8 studies (randomized controlled trials, n=3; quasi-experimental, n=5) enrolled 193 participants with Multiple Sclerosis. Studies were conducted in the USA (n=3), Europe (n=3), Iran, (n=1), and India (n=1). A total of 3 studies reported using the Yang style of Tai Chi (not specified, n=5 studies). The Tai Chi intervention averaged 27 sessions over 11 weeks. Study quality scores for the randomized controlled trials had a mean score of 23 (range 19-26), while quality scores for quasi-experimental studies had a mean score of 20 (range 13-26). Overall, participants enrolled in Tai Chi had better balance, gait and flexibility, less fatigue and depression, and better quality of life after the intervention; though mixed results were reported.

CONCLUSION

The results indicate that Tai Chi is likely safe and may provide physical and psychosocial benefits in individuals with Multiple Sclerosis. Further research is needed using more rigorous study designs to assess the benefits of Tai Chi for individuals with Multiple Sclerosis.

Tai Chi vs. combined exercise prescription: A comparison of their effects on factors related to falls

BACKGROUND

Regular exercise training is one of the core components of multifactorial fall-prevention programs.

OBJECTIVE

To compare the effect of Tai Chi and combined exercise prescription that consists of three main components of an exercise prescription on static balance, dynamic balance, fear of falling and mood.

METHODS

Sixty older adults aged 55-76 were randomly assigned to Group 1 (Tai Chi exercise) or Group 2 (combined exercise prescription). Exercise was performed three times a week over a period of 12 weeks. Single Leg-Stance-Eyes Open (SLS-EO), Single Leg-Stance Eyes Closed (SLS-EC), computerized balance measurements, the Timed Up and Go (TUG) test, Berg Balance Scale (BBS), the Survey of Activities and Fear of Falling in the elderly (SAFFE), the Geriatric Depression Scale (GDS), and the Beck Depression Scale (BDS) were assessed before and after the final training session.

RESULTS

Both exercise groups yielded better results in dynamic balance assessments (TUG and BBS) at the 12th week (p< 0.05). Group 1 also showed significant improvements in the measurements of SLS-EO, SLS-EC, SAFFE, GDS, and BDS during the post-intervention period (all p< 0.05). When the groups were compared, a significant difference was found between groups in favor of Group 1 in terms of the SLS-EO and SAFFE (p< 0.05).

CONCLUSIONS

It can be concluded that Tai Chi may be a more successful exercise intervention for factors-related to falls in older people.

The effects of Tai Chi on physical function and well-being among persons with Parkinson's Disease: A systematic review

Current medical treatments for Parkinson's disease (PD) are mainly palliative, though research indicates Tai Chi exercise improves physical function and well-being. An electronic database search of PubMed, CINAHL, Web of Science, Cochrane Library, PsycINFO and Embase was conducted, to examine current scientific literature for potential benefits of Tai Chi on physical function and well-being among persons with PD. A total of 11 studies met the inclusion criteria: 7 randomized clinical trials and 4 quasi-experimental studies. PD participants (n = 548) were on average age 68 years old and 50% women. Overall, participants enrolled in Tai Chi had better balance and one or more aspect of well-being, though mixed results were reported. Further research is needed with more rigorous study designs, larger sample sizes, adequate Tai Chi exercise doses, and carefully chosen outcome measures that assess the mechanisms as well as the effects of Tai Chi, before widespread recommendations can be made.
