Physical therapy and occupational therapy in Parkinson's disease

Specialized Allied Health Care for Parkinson's Disease: State of the Art and Future Directions

People with Parkinson's disease (PD) experience a range of progressive motor and non-motor symptoms, that negatively affect their daily functioning, social participation and quality of life. Allied health therapies have emerged as an effective treatment approach-complementary to pharmacological and neurosurgical treatments-which reduces the impact of PD in daily life. In this article, we propose criteria for what constitutes specialized allied health care for PD, and we review allied health research in PD in terms of meeting these criteria and its outcomes for monodisciplinary approaches as well as multi- or interdisciplinary allied health interventions. We focus on the three most studied allied health disciplines in PD: physical therapy, occupational therapy and speech-language therapy. Overall, the available evidence underscores the importance and potential benefits of specialized allied health care for people with PD. Our proposed criteria and recommendations for future research might help in further delineating specialized allied health care.

Pain characterization in patients with Parkinson's disease

BACKGROUND

Patients with Parkinson's disease (PD) often report chronic pain, which is one of the most complex non-motor symptoms. Therefore, this study aims to review the literature on the characteristics of pain in patients with PD.

METHODS

A systematic literature review was conducted following MOOSE recommendations. Observational studies reporting pain in patients with PD were included. No time restrictions were applied, but studies in Portuguese, Spanish, and English were considered. The search was performed in PubMed®, LILACS, and SciELO databases.

RESULTS

Twenty-six articles of observational studies were identified, reporting an average pain prevalence of 67.36%, emphasizing the significance of this symptom in the PD population. Pain was reported in various body regions, including lower limbs, upper limbs, lumbar spine, cervical spine, and other joints. Pain classification varied, encompassing musculoskeletal pain, PD-related pain, neuropathic pain, and dystonic pain, among others.

DISCUSSION

Pain in patients with PD is a prevalent and multifactorial condition, significantly impacting patients' quality of life.

CONCLUSION

Heterogeneity in data across included studies was observed, highlighting the need for additional research to elucidate the underlying mechanisms of pain in patients with PD and develop effective therapeutic strategies to address this symptom and improve the quality of life for individuals living with the disease.

Effect of Boxing Exercises on the Functional Ability and Quality of Life of Individuals with Parkinson's Disease: A Systematic Review

Parkinson's disease (PD) is a neurological disorder caused by the loss of dopamine-producing cells in the substantia nigra and characterized by motor and non-motor symptoms. Boxing is a type of complementary therapy to improve symptoms in PD. The purpose of the present study was to examine the effect of boxing training on the functionality and quality of life of patients with PD. The literature search was performed on PubMed, Scopus, PEDro, Cochrane Library, and Google Scholar search engines. The PEDro scale was used to assess the methodological quality of the studies. This systematic review included three studies that examined disease severity, mobility, physical activity, balance, and quality of life. According to the PEDro scale criteria, the three articles included were of high methodological quality. Statistically significant improvements after the implementation of boxing training was shown for balance and quality of life in contrast to the other variables. Boxing training intervention programs had a positive effect on balance and quality of life in patients with PD; however, the results are conflicting regarding certain functionality variables. Therefore, it is necessary to conduct further research to examine the effectiveness of boxing training on the functionality and quality of life of patients with Parkinson's disease.

A Delphi Panel of People With Parkinson's Disease Regarding Responsibility: Toward a Preliminary Taxonomy

IMPORTANCE

A sense of agency is associated with complex occupation-related responsibilities. A taxonomy can guide clinicians in enhancing responsibility in patients with Parkinson's disease (PwPD).

OBJECTIVE

To (1) discover levels of responsibility in occupations for PwPD and (2) propose a taxonomy for occupations.

DESIGN

A two-round Delphi study with PwPD and a one-round Delphi study with international experts.

SETTING

Electronic survey.

PARTICIPANTS

PwPD (N = 75) and international experts (N = 8).

OUTCOMES AND MEASURES

PwPD expressed their levels of an inherent sense of responsibility for each occupation (1 = very low responsibility, 5 = very high responsibility). International experts rated their level of agreement (5 = strongly agree, 1 = strongly disagree) with each dimension of the taxonomy. A consensus was determined to have been reached if the interquartile range was ≤1 and 70% agreement in two adjacent categories was achieved.

RESULTS

Thirty-three occupation categories were deemed as having very high to moderate responsibility for PwPD. Consequences of actions and the presence of others made up the two-dimensional responsibility taxonomy. Occupations have more challenging responsibility characteristics when they are performed with free choice, a level of high physical effort, alone, and with moral consequences.

CONCLUSIONS AND RELEVANCE

This study yielded the first consensus among PwPD regarding responsibility in occupations as well as a classification system for charting the complexity of responsibility in occupations. The occupation list we have created can be beneficial to health care professionals when providing interventions or conducting outcome assessments. Plain-Language Summary: When planning interventions for patients with Parkinson's disease, it can be helpful for clinicians to be aware of patients' perspectives regarding their sense of responsibility to perform occupations. The use of a systematic sequence of challenging occupations with responsibility attributes ranging from less complex to more complex can help enhance patient occupational participation.

Experiences of patients with Parkinson's disease belonging to an association. A qualitative approach

INTRODUCTION

Parkinson's disease (PD) affects the physical, cognitive, emotional, and social domains of people who suffer it. A good strategy for patients is to belong to an Association, using the services they offer.

OBJECTIVE

The aim of this study was to explore the experiences and perceptions of patients with PD in a Parkinson's Association.

METHODS

A sample of participants with PD who met the inclusion criteria was selected through purpose and theoretical sampling. Semi-structured qualitative interviews were used to collect the data, which was analyzed by thematic phenomenological analysis. Different strategies such as triangulation between researchers were used to ensure methodological rigor.

RESULTS

The data analyzed from 10 participants led to two themes: the context of the Association, where the importance of interdisciplinary treatments and the relationship with other patients is collected; and how they see their future, which describes the future perspectives that patients with PD have.

DISCUSSION

Patients agree on the importance of belonging to the Association, feeling part of a group, while benefiting from receiving therapies from the interdisciplinary team. The Association plays a relevant role in the evolution of the disease, as it influences how patients imagine their future. Developing strategies based on a good therapeutic alliance with professionals at the service of patients promotes the empowerment, adherence and continuity of treatments at home, which results in improving the quality of life of patients with PD.

Therapeutic Effect and Side Effects of Pharmacotherapy in Patients With Parkinson Disease and Myasthenia Gravis: A Systematic Review of Case Reports and Case Series Studies

PURPOSE

The co-existence of Parkinson disease (PD) and myasthenia gravis (MG) in an individual should be exceptionally rare. The purpose of this study was to systematically review the current literature regarding the therapeutic effect and side effects of pharmacotherapy on patients with PD and MG.

METHODS

Five bioscience and engineering databases (MEDLINE via PubMed, Cochrane Library, Scopus, EMBASE, and China National Knowledge Infrastructure) were searched from inception through February 21, 2022. Case reports and case series studies investigating pharmacotherapy in patients with PD and MG were included. Procedures were followed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The methodologic quality of included studies was evaluated by using the National Institutes of Health Quality Assessment Tool for Case Series Studies.

FINDINGS

Sixteen case reports and 5 case series studies with 32 participants met the inclusion criteria. Eight studies were rated as good quality, 10 were fair quality, and 3 were poor quality. The side effects of pharmacotherapy for PD or MG led to another disease, indicating an imbalance between dopamine and acetylcholine within human bodies.

IMPLICATIONS

When treating a patient who has PD or MG, health providers should be cautious about the occurrence of another disease. Timely treatment must rely on monitoring new symptoms as soon as the pharmacotherapy for PD or MG is initiated. Physical therapy may be helpful in decreasing the side effects of pharmacotherapy in patients with PD and MG. A new treatment pattern of pharmacotherapy + physical therapy for patients with PD and MG warrants further research.

[The role of occupational therapy in Parkinson's disease]

Occupational therapy works with Parkinson's sufferers and their caregivers to help them maintain or resume their activities of daily living and their independence, by recommending environmental adaptations, technical aids, compensation strategies and functional training.

Exercise and physical activity promotion for people newly diagnosed with Parkinson's disease: a UK survey exploring current practice and the views of healthcare professionals

OBJECTIVES

Exercise and physical activity (PA) are increasingly recognized as important components in the management of Parkinson's disease (PD). Their promotion at diagnosis is essential for better management of symptoms and overall well-being. Healthcare professionals (HCPs) are pivotal to the promotion of exercise and PA, but there is limited guidance on the content of such interventions. This study describes current practice, and explores views of HCPs around PA and exercise promotion at diagnosis for people with PD (PwP) DESIGN: A cross-sectional study using an anonymous online survey.

PARTICIPANTS

HCPs working with PwP in the UK.

RESULTS

Twenty-nine doctors, 17 nurses and 106 physiotherapists completed the survey. All nurses, 99% of physiotherapists and 72% of doctors reported that they always promote exercise and PA during clinic appointments. HCPs identified how PA impacts PD symptoms, evidence on the role of exercise, and signposting to support groups as core topics in PA promotion for PwP. However, these topics are mainly addressed during physiotherapy appointments. Referrals to physiotherapy occur most frequently when PwP experience falls or mobility issues, rather than at diagnosis. HCPs (52% doctors and 41% of nurses) identified lack of confidence as a barrier to prescribing exercise to PwP.

CONCLUSION

The importance of promoting PA at diagnosis is widely acknowledged by HCPs. There are variations between disciplines in terms of the tools used, and the timing and duration of interventions. Previously identified barriers to exercise promotion were also found in this study, and should be explored further in order to aid the implementation of effective interventions.

Association of health behaviors with function and health-related quality of life among patients with Parkinson's disease

BACKGROUND

Current evidence on chronic conditions favors promotion of health behaviors as a mean to positively impact health outcomes. In Parkinson's disease, performing health behaviors is indicated as a means to fight the long-lasting burden of the disease. Understanding actual engagement in health behaviors and patient activation and their association to function and health-related quality of life is therefore important. Our objectives were, among people with Parkinson's disease: (1) to characterize health behaviors including utilization of rehabilitative treatments, physical activity, and patient activation levels, and (2) to test the associations between these health behaviors and health outcomes.

METHODS

A cross-sectional study of 88 people with Parkinson's disease (age 66.84 ± 8.8) was conducted. Participants answered questionnaires measuring health behaviors including utilization of health professions treatments, physical activity, patient activation, and health outcomes consisting of function and health-related quality of life. Linear regression models were conducted to test associations between measured health behaviors, function and health-related quality of life.

RESULTS

Participants rarely engage in rehabilitative treatments, but showed high levels of patient activation. Controlled by demographics and disease severity, physical activity and patient activation were associated with function (b = 0.41, p < .001; b = 0.2, p = .02, respectively) and physical activity but not patient activation, which was associated with health-related quality of life (b = 0.19, p = .03). There was also interaction effects of physical activity and non-motor symptoms, and physical activity and motor symptoms on health-related quality of life (b = 0.19, p = .02 and b = - 0.22, p = .01, respectively).

CONCLUSIONS

In respect to their potential health-related benefits for people with Parkinson's disease, health professionals' treatments are underutilized. Findings supported the importance of health behaviors for maintaining function and health-related quality of life among people with Parkinson's disease. They also show a differential contribution of motor and non-motor symptoms to the association between physical activity and quality of life. It is suggested that policy makers encourage opportunities for physical activity tailored for people with Parkinson's disease and adopt a proactive stance towards enhancing awareness and use of rehabilitation services.

Clair KA, Toledo S, York MK, Todaro R, Yarab N, Wallock K. Delivering Multidisciplinary Rehabilitation Care in Parkinson's Disease: An International Consensus Statement

BACKGROUND

Parkinson's disease (PD) is a complex neurodegenerative disorder impacting everyday function and quality of life. Rehabilitation plays a crucial role in improving symptoms, function, and quality of life and reducing disability, particularly given the lack of disease-modifying agents and limitations of medications and surgical therapies. However, rehabilitative care is under-recognized and under-utilized in PD and often only utilized in later disease stages, despite research and guidelines demonstrating its positive effects. Currently, there is a lack of consensus regarding fundamental topics related to rehabilitative services in PD.

OBJECTIVE

The goal of the international Parkinson's Foundation Rehabilitation Medicine Task Force was to develop a consensus statement regarding the incorporation of rehabilitation in PD care.

METHODS

The Task Force, comprised of international multidisciplinary experts in PD and rehabilitation and people directly affected by PD, met virtually to discuss topics such as rehabilitative services, existing therapy guidelines and rehabilitation literature in PD, and gaps and needs. A systematic, interactive, and iterative process was used to develop consensus-based statements on core components of PD rehabilitation and discipline-specific interventions.

RESULTS

The expert-based consensus statement outlines key tenets of rehabilitative care including its multidisciplinary approach and discipline-specific guidance for occupational therapy, physical therapy, speech language pathology/therapy, and psychology/neuropsychology across all PD stages.

CONCLUSIONS

Rehabilitative interventions should be an essential component in the comprehensive treatment of PD, from diagnosis to advanced disease. Greater education and awareness of the benefits of rehabilitative services for people with PD and their care partners, and further evidence-based and scientific study are encouraged.

REHABS: An Innovative and User-Friendly Device for Rehabilitation

Rehabilitation is a complex set of interventions involving the assessment, management, and treatment of injuries. It aims to support and facilitate an individual's recovery process by restoring a physiological function, e.g., limb movement, compromised by physical impairments, injuries or diseases to a condition as close to normal as possible. Innovative devices and solutions make the rehabilitation process of patients easier during their daily activities. Devices support physicians and physiotherapists in monitoring and measuring patients' physical improvements during rehabilitation. In this context, we report the design and implementation of a low-cost rehabilitation system, which is a programmable device designed to support tele-rehabilitation of the upper limbs. The proposed system includes a mechanism to acquire and analyze data and signals related to rehabilitation processes.

Therapeutic considerations of bioactive compounds in Alzheimer's disease and Parkinson's disease: Dissecting the molecular pathways

Leading neurodegenerative diseases Alzheimer's disease (AD) and Parkinson's disease (PD) are characterized by the impairment of memory and motor functions, respectively. Despite several breakthroughs, there exists a lack of disease-modifying treatment strategies for these diseases, as the available drugs provide symptomatic relief and bring along side effects. Bioactive compounds are reported to bear neuroprotective properties with minimal toxicity, however, a detailed elucidation of their modes of neuroprotection is lacking. The review elucidates the neuroprotective mechanism(s) of some of the major phyto-compounds in pre-clinical and clinical studies of AD and PD to understand their potential in combating these diseases. Curcumin, eugenol, resveratrol, baicalein, sesamol and so on have proved efficient in countering the pathological hallmarks of AD and PD. Curcumin, resveratrol, caffeine and so on have reached the clinical phases of these diseases, while aromadendrin, delphinidin, cyanidin and xanthohumol are yet to be extensively explored in pre-clinical phases. The review highlights the need for extensive investigation of these compounds in the clinical stages of these diseases so as to utilize their disease-modifying abilities in the real field of treatment. Moreover, poor pharmacokinetic properties of natural compounds are constraints to their therapeutic yields and this review suggests a plausible contribution of nanotechnology in overcoming these limitations.

Visual Dysfunction and Occupational Performance in Persons With Parkinson's Disease

IMPORTANCE

Visual function is critical to support occupational performance for persons with Parkinson's disease (PwP), yet it can be adversely affected by the disease.

OBJECTIVE

To evaluate the prevalence and general awareness of visual dysfunction and identify the association between visual dysfunction and occupational performance in PwP.

DESIGN

Self-reported cross-sectional electronic survey.

PARTICIPANTS

PwP, identified from a registered database at a neurological institute, were invited to complete the survey through emails and newsletters.

OUTCOMES AND MEASURES

The survey contained items of self-reported visual difficulties, diagnosed eye conditions, and about general awareness about disease-related visual dysfunction. Ophthalmological symptoms and occupational performance were measured with the Visual Impairment Parkinson's disease Questionnaire and the Revised Self-Reported Functional Visual Performance Scale, respectively.

RESULTS

Data from PwP (n = 92; Mage = 69 yr) were analyzed. Nearly half were unaware that their disease could affect vision. Awareness was not associated with disease duration. Individuals reporting awareness tended to report difficulties with vision. Functional activities requiring vision were mildly impaired, and the frequency of ophthalmologic symptoms (commonly related to ocular surface disorder) was low. Nevertheless, a higher frequency of ophthalmologic symptoms was positively associated with a higher degree of disability in activities of daily living (Spearman's ρ = .49, p < .01).

CONCLUSIONS AND RELEVANCE

Visual dysfunction related to Parkinson's disease may affect occupational performance. Screening for changes in vision in these individuals may aid occupational therapists in addressing functional independence and activity engagement. What This Article Adds: People with Parkinson's disease may not have a general awareness that the disease can adversely affect visual function. Those individuals with awareness tend to notice changes in vision, and this disease-related visual dysfunction may limit engagement and participation in everyday activities. Active evaluation of visual function in people with Parkinson's disease is recommended. Occupational therapists could play a key role by screening for visual dysfunction and providing patient education in the clinic.

Lower Limb Muscle Fatigue Alters Spatiotemporal Gait Parameters and Turning Difficulty Characteristics in Parkinson's Disease

OBJECTIVE

To determine the effects of lower limb muscle fatigue on spatiotemporal gait parameters and turning difficulty characteristics during the extended Timed Up and Go (extended TUG) test in individuals with different severity stages of Parkinson's disease (PD).

METHODS

Forty individuals with PD, classified as Hoehn and Yahr (H&Y) stages 2 and 3 participated in this pre- and post-experimental study design. The participants performed a continuous sit-to-stand task from a chair based on 30 cycles/min set-up to induce lower limb muscle fatigue. They performed extended TUG test immediately before and after completing the fatigue protocol. Spatiotemporal gait parameters and turning difficulty characteristics were recorded using two GoPro® Hero 4 Silver cameras. Data were subjected to a repeated-measure ANOVA.

RESULTS

Individuals with PD experience significant changes in spatiotemporal gait parameters, specifically stride velocity and length, under conditions of lower limb muscle fatigue (p=0.001). These changes were more pronounced in individuals with PD in the H&Y stage 3 group. Additionally, both PD groups exhibited difficulty with turning, requiring more than five steps to complete a 180° turn and taking more than 3 seconds to accomplish it.

CONCLUSION

These findings highlight the impact of muscle fatigue on gait performance in PD and suggest that individuals in later stages of the disease may be particularly affected. Further research is needed to explore interventions that can mitigate these gait impairments and improve mobility in individuals with PD.

Consensus on Feedback Statements That Create Responsibility Among People With Parkinson's Disease: A Delphi Study

IMPORTANCE

Sense of agency is associated with a sense of responsibility, which is essential to performing goal-directed occupations.

OBJECTIVE

To reach consensus on a set of extrinsic feedback statements that have the potential to create a sense of responsibility among patients with neurological disorders in the course of performing daily or social occupations.

DESIGN

Anonymous Delphi study with two rounds with international experts and one round with Irani patients with Parkinson's disease (PD).

SETTING

Electronic survey.

PARTICIPANTS

One hundred experts and 73 patients with idiopathic PD.

OUTCOMES AND MEASURES

Experts and patients anonymously rated (5 = strongly agree/very effective, 4 = agree/effective, 3 = neither agree nor disagree/uncertain, 2 = disagree/ineffective, 1 = strongly disagree/very ineffective) their level of agreement with each survey statement and the effectiveness of each statement in creating a sense of responsibility in the course of performing daily or social occupations. Consensus was set as an interquartile range of ≤1 and ≥70% agreement in two adjacent categories of a Likert scale.

RESULTS

In the experts' first round, consensus was reached on the level of agreement and effectiveness of 18 statements. In the second round, final consensus was achieved on all statements. In the one patient round, patients reached consensus on all statements. Finally, 34 statements were rated as 4 or 5 in terms of agreement and effectiveness, based on the opinions of experts and patients.

CONCLUSIONS AND RELEVANCE

This study has produced a collection of feedback statements that might be useful in occupation-based interventions. What This Article Adds: Extrinsic responsibility feedback delivered while administering occupation-based interventions may increase volition, motivation, and engagement.

"It's a lot more complicated than it seems": physiotherapists' experiences of using compensation strategies in people with Parkinson's

Background

Gait disturbances often result in functional limitations in daily activities and negatively impact the quality of life in people with Parkinson's disease. Physiotherapists often employ compensation strategies in an attempt to improve patients' walking. However, little is known about physiotherapists' experiences in this regard. We evaluated how physiotherapists adopt compensation strategies and what they draw on to inform their clinical decision-making.

Methods

We carried out semi-structured online interviews with 13 physiotherapists with current or recent experience working with people with Parkinson's disease in the United Kingdom. Interviews were digitally recorded and transcribed verbatim. Thematic analysis was utilized.

Results

Two main themes were developed from the data. The first theme, optimizing compensation strategies through personalized care, shows how physiotherapists accounted for the individual needs and characteristics of people with Parkinson's, which resulted in them individually tailoring compensation strategies. The second theme, delivering compensation strategies effectively, considers the available support and perceived challenges with work settings and experience that impact physiotherapists' ability to deliver compensation strategies.

Discussion

Although physiotherapists strived to optimize compensation strategies, there was a lack of formal training in this area, and their knowledge was primarily acquired from peers. Furthermore, a lack of specific knowledge on Parkinson's can impact physiotherapists' confidence in maintaining person-centered rehabilitation. However, the question that remains to be answered is what accessible training could address the knowledge-practice gap to contribute to the delivery of better-personalized care for people with Parkinson's.

Fear of Falling Avoidance Behavior in Parkinson's Disease: Most Frequently Avoided Activities

BACKGROUND

Fear of falling avoidance behavior (FFAB) is common in Parkinson's disease (PD).

OBJECTIVES

The objectives of the study are to determine what activities are most avoided due to FFAB among people with PD and whether any associations exist with demographic factors or fall history.

METHOD

Cross-sectional analysis of 174 individuals with PD using the Modified FFAB Questionnaire.

RESULTS

Walking in dimly lit, unfamiliar places, and different surfaces, lifting and carrying objects, walking in crowded places, recreational/leisure activities, and going up/downstairs were most avoided. Fallers reported more FFAB (ps < .029). FFAB for certain activities was associated with increased or decreased odds of falling.

CONCLUSION

Individuals with PD avoid walking in compromised situations and engaging in recreational/leisure activities due to FFAB. While excessive FFAB may increase the odds of falling, protective forms may be associated with decreased odds. Targeting FFAB among individuals with PD may increase safe participation in meaningful occupations in the home and community.

Feasibility and informativeness of the Canadian occupational performance measure for identifying priorities in patients with Parkinson's disease

OBJECTIVE

The aim of this study was to examine the feasibility and informativeness of the Canadian Occupational Performance Measure (COPM) for identifying the priorities of patients with Parkinson's disease (PD).

METHODS

The COPM was administered in patients with PD who were admitted to the hospital. Feasibility was investigated by confirming the acceptability and practicality of the COPM interview. To investigate informativeness, identified priorities were classified according to the International Classification of Functioning, Disability and Health (ICF) and were cross-referenced with data from similar studies using the Patient-Specific Functional Scale (PSFS) and the Patient-Specific Index for PD (PSI-PD).

RESULTS

All 61 patients who participated in this study completed the COPM, and a total of 197 priorities were identified. The most frequently identified priorities were "Recreation and leisure," "Preparing meals," "Walking," "Doing housework," and "Caring for household objects." The priorities identified using the PSFS and the PSI-PD were less diverse and focused on "Mobility" or "Self-care."

CONCLUSIONS

The COPM is a feasible and informative tool for identifying priorities in patients with PD. Its informativeness was demonstrated by its ability to identify diverse priorities across the ICF domains of "Activity and participation" that had not been identified in the studies using the PSFS and PSI-PD.

Specialized Versus Generic Allied Health Therapy and the Risk of Parkinson's Disease Complications

BACKGROUND

Specialized versus generic physiotherapy (PT) reduces Parkinson's disease (PD)-related complications. It is unclear (1) whether other specialized allied heath disciplines, including occupational therapy (OT) and speech and language therapy (S&LT), also reduce complications; (2) whether there is a synergistic effect among multiple specialized disciplines; and (3) whether each allied health discipline prevents specific complications.

OBJECTIVES

To longitudinally assessed whether the level of expertise (specialized vs. generic training) of PT, OT, and S&LT was associated with the incidence rate of PD-related complications.

METHODS

We used claims data of all insured persons with PD in the Netherlands between January 1, 2010, and December 31, 2018. ParkinsonNet-trained therapists were classified as specialized, and other therapists as generic. We used mixed-effects Poisson regression models to estimate rate ratios adjusting for sociodemographic and clinical characteristics.

RESULTS

The population of 51,464 persons with PD (mean age, 72.4 years; standard deviation 9.8) sustained 10,525 PD-related complications during follow-up (median 3.3 years). Specialized PT was associated with fewer complications (incidence rate ratio [IRR] of specialized versus generic = 0.79; 95% confidence interval, [0.74-0.83]; P < 0.0001), as was specialized OT (IRR = 0.88 [0.77-0.99]; P = 0.03). We found a trend of an association between specialized S&LT and a lower rate of PD-related complications (IRR = 0.88 [0.74-1.04]; P = 0.18). The inverse association of specialized OT persisted in the stratum, which also received specialized PT (IRR = 0.62 [0.42-0.90]; P = 0.001). The strongest inverse association of PT was seen with orthopedic injuries (IRR = 0.78 [0.73-0.82]; P < 0.0001) and of S&LT with pneumonia (IRR = 0.70 [0.53-0.93]; P = 0.03).

CONCLUSIONS

These findings support a wider introduction of specialized allied health therapy expertise in PD care and conceivably for other medical conditions. © 2022 The Authors. Movement Disorders published by Wiley Periodicals LLC on behalf of International Parkinson and Movement Disorder Society.

Complex Rehabilitation of Patients with Parkinson’s Disease

Aim: To assess the clinical effectiveness of a comprehensive rehabilitation program for patients with Parkinson’s disease Materials and Methods: The study was conducted in the regional center for movement disorders (Odesa, Ukraine). 90 patients with 1-2.5 Hoehn-Yahr stage were examined. Patients were randomly assigned to three groups (I (n=30) – standard drug therapy, II (n=30) – standard drug therapy +physical therapy, III (n=30) – standard drug therapy +physical therapy+ art therapy). The effectiveness of the therapy was assessed using the UPDRS questionnaires, Beck Depression Inventory (BDI), Montreal Cognitive Assessment (MoCA), and Pegboard Test. The follow-up period was 12 months. Results: Patients of the II and III groups noted an improvement in mood after physical exertion. They observed a decrease in daytime sleepiness, a decrease in tremors, and a decrease in the intensity of anxiety and fear. During the observation period, signs of disease progression were observed only in 4 (13.3%) patients of group II, in 2 (6.7%) patients of group III and in 12 (40.0%) ) patients of the control group (respectively, χ2 = 4.18 p = 0.04 and χ2 = 7.55 p = 0.006) Conclusions: 1. The use of complex rehabilitation allows to reduce the severity of motor and non-motor manifestations of Parkinson's disease. 2. The inclusion of art therapy in the complex rehabilitation program allows to halve the number of cases of disease progression. 3. The positive effect of the use of comprehensive rehabilitation is maintained throughout the observation period.

Improvement of Balance, Motor Aspects, and Activities of Daily Living in Parkinson's Disease after a Sequential Multimodal Aquatic- and Land-Based Intervention Program

Parkinson's disease (PD) is a neurodegenerative, with heterogeneous clinical conditions and motor changes that reduce functioning. Postural instability is one of the motor aspects of disease progression, with a potential increase in the risk of falls, consequently affecting the activities of daily living (ADL). The objective of this study was to verify the influence of a multimodal intervention program (MIP) sequentially applied in aquatic- (AEs) and land-based environments (LEs) on balance, postural control, motor activities, and ADL in people with PD. It is an interventional clinical study with patients in stages 1 to 4 in the Hoehn and Yahr scale, assessed with Berg Balance Scale (BBS), Mini-Balance Evaluation System Test (Mini-BESTest), Unified Parkinson's Disease Rating Scale (UPDRS) II and III, Dynamic Gait Index (DGI), and quiet stance (QS) analysis in a force platform. The MIP was conducted sequentially with aquatic- (AIs) and land-based interventions (LIs) for 12 weeks each, twice a week, each session lasting 1 hour, and a 12-week interval between interventions. The comparison analysis was made with Friedman ANOVA, and the multiple comparisons with Wilcoxon signed-rank, Bonferroni correction, and effect size (r). The sample comprised 18 people with PD (66.83 ± 11.74 years). The AI and the full intervention (FI) had a large effect according to BBS. With Mini-BESTest, the LI and FI had a large effect. According to UPDRS II, the MIP improved ADL after LI, with a medium effect, and the motor aspects of UPDRS III improved after LI and FI, with a large effect. DGI was not sensitive in the analyses, with a ceiling effect after FI. No differences were identified in QS analyses. This research identified improved balance, ADL, and motor aspects in people with PD after sequential MIP in AI and LI, indicating that land-based and aquatic interventions are complementary and advantageous to people with PD.

Timing of Physical Therapy Sessions for Individuals With Parkinson Disease May Unlock Benefits

This Viewpoint advocates for careful consideration in the timing of physical therapy for individuals with Parkinson disease as a possible avenue toward improved outcomes.

Can we really 'read' art to see the changing brain? A review and empirical assessment of clinical case reports and published artworks for systematic evidence of quality and style changes linked to damage or neurodegenerative disease

The past three decades have seen multiple reports of people with neurodegenerative disorders, or other forms of changes in their brains, who also show putative changes in how they approach and produce visual art. Authors argue that these cases may provide a unique body of evidence, so-called 'artistic signatures' of neurodegenerative diseases, that might be used to understand disorders, provide diagnoses, be employed in treatment, create patterns of testable hypotheses for causative study, and also provide unique insight into the neurobiological linkages between the mind, brain, body, and the human penchant for art-making itself. However-before we can begin to meaningfully build from such emerging findings, much less formulate applications-not only is such evidence currently quite disparate and in need of systematic review, almost all case reports and artwork ratings are entirely subjective, based on authors' personal observations or a sparse collection of methods that may not best fit underlying research aims. This leads to the very real question of whether we might actually find patterns of systematic change if fit to a rigorous review-Can we really 'read' art to illuminate possible changes in the brain? How might we best approach this topic in future neuroscientific, clinical, and art-related research? This paper presents a review of this field and answer to these questions. We consider the current case reports for seven main disorders-Alzheimer's and Parkinson's disease, frontotemporal and Lewy body dementia, corticobasal degeneration, aphasia, as well as stroke-consolidating arguments for factors and changes related to art-making and critiquing past methods. Taking the published artworks from these papers, we then conduct our own assessment, employing computerized and human-rater-based approaches, which we argue represent best practice to identify stylistic or creativity/quality changes. We suggest, indeed, some evidence for systematic patterns in art-making for specific disorders and also find that case authors showed rather high agreement with our own assessments. More important, through opening this topic and past evidence to a systematic review, we hope to open a discussion and provide a theoretical and empirical foundation for future application and research on the intersection of art-making and the neurotypical, the changed, and the artistic brain.

Socially Assistive Robots for Parkinson's Disease: Needs, Attitudes and Specific Applications as Identified by Healthcare Professionals

To explore how socially assistive robots (SARs) may assist the specific needs of individuals with Parkinson's disease (IwPD), we conducted three focus groups with 12 clinicians who treat IwPD. We present a thematic analysis of their perceptions of the needs of the patients, and their own expectations, perceived advantages, disadvantages and concerns regarding the use of SARs for IwPD. Clinicians were positive towards using SARs for IwPD, if used in the patient's home, for motor, communication, emotional, and cognitive needs, especially for practice and for help with activities of daily living. They were concerned that a SAR might be used to replace clinicians’ work, and stressed it should only augment the clinicians’ work. They thought a SAR may relieve some of the burden experienced by informal caregivers, and identified specific applications for SARs for PD. We asked 18 stakeholders (nine IwPD, nine family members) to rate their level of agreement with the clinicians’ statements. The greatest divergence between their views and those of the clinicians was on the topic of using a SAR as a companion, or as a feeding assistant, to which they objected. This work may be used as a basis for future studies designing SARs for IwPD.

Exploring health and social services in Denmark, Norway, Spain and the United Kingdom for the development of Parkinson's care pathways. A document analysis

People with Parkinson's disease (PD) may find it difficult to identify and access the wide number of services they need and are entitled to along their complex PD journey. As part of the project OPTIM-PARK - Optimisation of community resources and systems of support to enhance the process of living with Parkinson's Disease, document analysis was developed to create overviews of existing resources and systems of support in Denmark, Norway, Spain and the United Kingdom. Documents on community resources, policies, guidelines and professional recommendations were the main sources of information. They were sought systematically at official websites of the public sector (national and regional levels) and websites of non-governmental organisations and scientific societies; searches were performed in October 2020 and updated in September 2021. A higher-level cross-national content analysis integrated all the country-specific information. Data- and concept-driven coding frames were developed; trial coding and peer review strengthened face validity and reliability. The analysis led to overviews of: (1) Key aims at patient and societal levels. (2) Key elements in form of professional approaches. (3) Community resources. (4) Legally anchored services. In general, clear descriptions of how to implement care pathways and tools to facilitate delivery were missing in the included documents, and pathways and guidelines did not include referral to general social support, social security support or labour and employment support. The results shed light on the complex support systems and resources and can inspire the planning of more comprehensive care pathways for people with PD and other long-term conditions.

Molecular and Cellular Interactions in Pathogenesis of Sporadic Parkinson Disease

An increasing number of the population all around the world suffer from age-associated neurodegenerative diseases including Parkinson’s disease (PD). This disorder presents different signs of genetic, epigenetic and environmental origin, and molecular, cellular and intracellular dysfunction. At the molecular level, α-synuclein (αSyn) was identified as the principal molecule constituting the Lewy bodies (LB). The gut microbiota participates in the pathogenesis of PD and may contribute to the loss of dopaminergic neurons through mitochondrial dysfunction. The most important pathogenetic link is an imbalance of Ca²⁺ ions, which is associated with redox imbalance in the cells and increased generation of reactive oxygen species (ROS). In this review, genetic, epigenetic and environmental factors that cause these disorders and their cause-and-effect relationships are considered. As a constituent of environmental factors, the example of organophosphates (OPs) is also reviewed. The role of endothelial damage in the pathogenesis of PD is discussed, and a ‘triple hit hypothesis’ is proposed as a modification of Braak’s dual hit one. In the absence of effective therapies for neurodegenerative diseases, more and more evidence is emerging about the positive impact of nutritional structure and healthy lifestyle on the state of blood vessels and the risk of developing these diseases.

Effects of Multimodal Rehabilitation on the Activities of Daily Living, Quality of Life, and Burden of Care for Patients with Parkinson's Disease: A Randomized Control Study

Background: Parkinson’s disease reduces patients’ function, activities of daily living, and quality of life, and increases their guardians’ burden of care. This study verified the effectiveness of a multimodal rehabilitation programme for patients with Parkinson’s disease. Trial design: This study was a multicentre parallel randomised controlled, single-blind, trial conducted in three hospitals in Korea. Methods: A central randomisation centre used computer generated tables to randomly allocate 60 of 75 patients with Parkinson’s disease who fulfilled the study requirements into experimental (n = 30; multimodal rehabilitation; consisting of daily living training, guardian education, home environment modification, fine muscle exercise, balance training, and training using auxiliary tools performed 50 min per session, twice a week, in 10 sessions) and control (n = 30; traditional rehabilitation; consisting of task-oriented training, joint exercise, and daily living training performed 50 min per session, twice a week, in 10 sessions) groups. Results: Multimodal rehabilitation for Parkinson’s disease significantly improved the activities of daily living (p < 0.01) and quality of life of patients (p < 0.001) and eased the guardians’ burden of care (p < 0.001). Conclusions: Multimodal rehabilitation is suggested to improve activities of daily living, quality of life of patients with Parkinson’s disease, and reduce the burden of care of their guardians.

Effectiveness of therapeutic massage for improving motor symptoms in Parkinson's disease: A systematic review and meta-analysis

Background

Parkinson's disease (PD) causes movement disorders [called motor symptoms (MS)], and motor dysfunction poses a great barrier to the quality of life. Although pharmacological therapy like levodopa can relieve the symptoms, it can also cause complications, such as psychosis, nausea, and dyskinesia. A therapy with more minor side effects is needed for PD. Therapeutic massages are the most commonly used forms of complementary and alternative medicine (CAM), but no systematic review and meta-analysis have focused on the efficacy of massage on PD.

Objective

To evaluate the quality of evidence and efficacy of therapeutic massage for improving MS in PD.

Methods

We independently searched four electronic databases, including Chinese National Knowledge Infrastructure (CNKI), MEDLINE/PubMed, Embase, and Cochrane Library, for randomized controlled trials (RCTs) about therapeutic massage and other available manual therapies improving MS in PD from January 1, 2012, to December 31, 2021 (recent 10 years). The main outcome measures were total effectiveness and the Unified Parkinson's Disease Rating Scale (UPDRS), including UPDRS total, II, and III. For the statistical analysis, the risk ratio, standard mean difference, and 95% confidence interval (CI) were used to calculate effect sizes between groups. To determine heterogeneity, statistical index I² was used.

Results

A total of 363 PD participants in seven RCTs and one randomized pilot-control study were included in this meta-analysis. The total effectiveness showed that therapeutic massage was more effective than the intervention of the control group for improving MS [ratio risk (RR): 1.33, 95% CI (1.14–1.55), p = 0.0002]. The UPDRS-III scores showed that massage improves motor function more than the control group [SMD = −0.46, 95% CI (−0.67, −0.24), p < 0.00001]. But we found that massage performed no better than the control group in improving daily life activities [SMD = −0.15, 95% CI (−0.40, 0.10), p = 0.23].

Conclusion

Therapeutic massage was effective in improving MS in PD. It is suggested to be an appropriate form of CAM in treating PD.

Physical Therapy for at Least 6 Months Improves Motor Symptoms in Parkinson’s Patients: A Meta-Analysis

Objective

Long-term physical therapy helps to improve the motor symptoms of patients with Parkinson's disease, but the effectiveness is not clear. The purpose of this study was to evaluate the effect of long-term physical therapy on improving motor symptoms or daily activities in Parkinson's patients with drug use or discontinuation, as well as its impact on drug treatment dose. A subgroup analysis was conducted on different treatment methods to determine the most effective treatment method.

Methods

The researchers independently searched databases, including PubMed, Medline, Embase, Ovid, Cochrane Library, and ISI Web of science. The search deadline was June 2022. A randomized controlled trial was conducted on Parkinson's disease patients with HY stages 1-3 who received continuous physical therapy for 6 months or more. Systematic evaluation and meta-analysis were carried out by using common clinical evaluation indicators, namely, MDS-UPDRS exercise score, daily activity (ADL) score, or LED dose. The quality of the literature was assessed using the modified Jadad scale of Cochrane's bias risk tool.

Results

A total of 523 Parkinson's disease patients with HY stages of 1-3 were included in the study. The results showed that long-term physical therapy could improve patients' motor symptoms with combined antiparkinsonian drugs (Z = 2.61 and P = 0.009) and had a significant positive effect on the motor symptoms of patients with discontinued antiparkinsonian drugs (Z = 2.73 and P = 0.006). Meanwhile, it could reduce the LED dose of patients with Parkinson's disease. The difference was statistically significant (Z = 2.58 and P = 0.010).

Conclusion

The results of this study indicated that physical therapy for at least 6 months or longer for patients with mild to moderate Parkinson's HY could effectively improve the motor symptoms of Parkinson's patients, whether or not combined with antiparkinson drugs. Meanwhile, long-term physical therapy reduced the LED dose of patients treated with drugs compared with patients in the control group who received short-term physical therapy, other types of intervention group, or no treatment.

Occupational Therapy for People with Early Parkinson’s Disease: A Retrospective Program Evaluation

Purpose

Clinical practice guidelines establish that occupational therapy (OT) services are indicated for people with early Parkinson's disease (PD). However, OT is uncommon compared to other rehabilitation services. This study describes the development and evaluation of a proactive, consultative OT program for people with early PD as a part of an integrated care approach.

Materials and Methods

The program was developed by an occupational therapist adapting practice guidelines for people with early PD. Retrospective program evaluation occurred at an outpatient rehabilitation clinic. The consultative OT program for early PD includes a 90-minute evaluation with instruction in self-management techniques, individually tailored exercises, and follow-up recommendations. The program was evaluated with the RE-AIM framework. Postprogram semistructured interviews provided patient-reported program effectiveness and satisfaction.

Results

In 2018, 23 individuals used OT out of 77 people with early PD who attended the proactive rehabilitation program. Most individuals (n = 16, 69.6%) were within Hoehn and Yahr stages 1-2 and were seen within 3 years of PD diagnosis. Participants presented with deficits in hand strength (60.0 ± 23.4 pounds) and dexterity (right hand 30.0 ± 8.0 seconds) and reported complaints about basic and/or instrumental activities of daily living (n = 15, 65.2%). Semistructured interviews (n = 16) revealed that most individuals (75%) reported high satisfaction. Of the 10 who recalled a home exercise program, 60% reported continued adherence. Consultative OT was delivered with fidelity in 22/23 individuals (96%). After one year, only two occupational therapists at one clinic had adopted the program, and the program is maintained in the organization.

Conclusion

Occupational therapists reached people in the early stages of PD when a specific program was tailored to evaluate and target their specific needs. Motor activity deficits noted in individuals with early PD support future scaling and sustainability efforts of OT within this population. Quality improvement suggestions are discussed for future implementation and clinical trials.

Occupational Therapy Practice Guidelines for People With Parkinson's Disease

IMPORTANCE

Occupational therapy practitioners address the occupational performance and participation needs of people with Parkinson's disease (PD) and their care partners.

OBJECTIVE

This Practice Guideline is informed by systematic reviews on the use of occupational therapy interventions to promote participation in occupations for people with PD and to facilitate their caregivers' participation in the caregiver role. This guideline is meant to support practitioners' clinical decision making when working with people with PD and their care partners.

METHOD

We examined and synthesized the results of four systematic reviews and integrated those results into clinical recommendations for practice.

RESULTS

Thirty-three articles from the systematic reviews served as the basis for the clinical recommendations in this Practice Guideline. Clinical recommendations are provided for interventions that have strong or moderate supporting evidence.

CONCLUSION AND RECOMMENDATIONS

Multidisciplinary, tailored, goal-oriented intervention is recommended for people with PD. Various forms of exercise can be used to improve activities of daily living and instrumental activities of daily living performance and social participation, and interventions should incorporate health behavior change techniques to support adequate physical activity levels in daily life. Mindfulness meditation and exercise can be used to support sleep, and task-oriented training can be used to improve performance of specific tasks. Occupational therapy practitioners should incorporate self-management, coaching, compensatory, cognitive-behavioral, and other approaches into multicomponent treatment plans depending on the client's needs and goals. Additional potentially appropriate intervention approaches or areas to address are discussed on the basis of existing or emerging evidence and expert opinion. What This Article Adds: This Practice Guideline provides a summary and applications of the current evidence supporting occupational therapy intervention for people with PD. It includes case examples and suggested decision-making algorithms to support practitioners in addressing client goals.

A randomized clinical trial of burst vs. spaced physical therapy for Parkinsons disease

INTRODUCTION

The optimal timing for physical therapy (PT) delivery in Parkinson's disease (PD) is unknown. Our objective was to determine whether spacing physical therapy visits over a longer period of time is beneficial for maintenance of physical function in PD.

METHODS

A single center, single-blinded, randomized controlled trial of PD participants. Participants (n = 30) were randomized to either burst (two PT sessions weekly for 6 weeks) or spaced (one PT session every 2 weeks for 6 months) PT. 11 participants in each arm completed the study and were analyzed. The primary outcome measure was the Timed Up and Go (TUG) test at baseline and 6 months. The burst group had an additional outcome measure timepoint at the completion of PT at 6 weeks.

RESULTS

Neither group achieved a minimal clinically significant benefit in the TUG score (3.5s) at 6 months. The spaced PT TUG scores were maintained when comparing baseline (7.8 ± 1.5s) and 6 month timepoints (7.8 ± 2.6s, p = 0.594). The burst group TUG scores comparing baseline (9.8 ± 3.8s) to 6 weeks (9.1 ± 3.0s) also was maintained (p = 0.365). The burst group worsened, however, when measuring the period from 6 weeks to 6 months (12.1 ± 7.6s, p = 0.034).

CONCLUSIONS

The spaced PT group had stability of the TUG mobility measure at 6 months, while the burst group had a significant worsening once PT was discontinued after 6 weeks. It is feasible to test these approaches in a future larger comparative effectiveness study.

Co-designing a remote rehabilitation tool for Parkinson's disease: exploratory values and challenges

BACKGROUND

Impaired motor function is one of the early symptoms shown in patients with Parkinson Disease (PD). For this reason, rehabilitative interventions have been used for many years to improve motor and non-motor symptoms. Among them, the use of music therapy has shown benefits in helping to overcome some of the most common motor dysfunction. Addressing the challenge of providing access to this type of therapy, this document presents the collaborative design process to develop a remote training support tool for PD based on music therapy.

METHODS

A qualitative study with creative co-design methods was used in which different groups of healthcare professionals, patients, and relatives participated in six iterative sessions. Workshops were designed and structured to incrementally discover requirements and needs and validate the proposed prototype ideas.

RESULTS

The study provided key aspects that were used for the development and validation of the proposed prototypes for the remote music-based training support tool for PD. Up to 20 factors that had a positive and/or negative influence on patient access to training were detected. These factors were classified into three common themes: daily activities and independence, participation in treatment and barriers to daily treatment, and self-management and personalization of information and telecommunication technologies (ICT).

CONCLUSIONS

This paper shows the results of a collaborative design process aimed at identifying the different factors, relevant to patients with PD, to improve their access to remote ICT-based training therapy and their expectations regarding alternative therapies, such as music. The participatory design methods and the iterative model used helped overcome many of the traditionally barriers that this type of technological support solutions usually have, facilitating the future participation.

Exercise Intolerance and Oxygen Desaturation in Patients with Parkinson's Disease: Triggers for Respiratory Rehabilitation?

The role that oxygen desaturation plays in exercise tolerance and its rehabilitative implications in patients with Parkinson's disease (PD) are unclear. We aimed to test exercise tolerance and oxygen saturation levels both during exercise and at night in PD patients to better define their rehabilitative needs. In clinically stable PD patients, undergoing inpatient rehabilitation, and in "ON" phase, we prospectively assessed clinical data, sleepiness, comorbidities, PD severity (Hoehn&Yahr, HY), motor function (ADLs, UPDRSII and UPDRSIII, Barthel Index, Functional Independence Measure), balance, spirometry, respiratory muscles (MIP/MEP), peak cough expiratory flow (PCEF), continuous night oxygen monitoring, and meters at 6MWT. Of 55 patients analyzed (28 with moderate-severe PD, HY ≥ 2.5), 37% and 23% showed moderate-severe impairment on UPDRSII and UPDRSIII, respectively; 96% had reduced exercise tolerance and severe respiratory muscles impairment (MIP/MEP < 45% pred.); 21.8% showed desaturations during exercise; and 12.7% showed nocturnal desaturations. At multiple regression, low exercise tolerance and low mean nocturnal and exercise-induced saturation correlated with several respiratory and motor function and disability indices (all p < 0.03). Exercise tolerance, exercise-induced desaturations, and nocturnal desaturations were extremely frequent in PD patients and were worse in more severe PD patients. This suggests considering a combined role for motor and respiratory rehabilitation in these patients.

Reciprocal Influence of Mobility and Speech-Language: Advancing Physical Therapy and Speech Therapy Cotreatment and Collaboration for Adults With Neurological Conditions

Mobility and speech-language impairments and limitations in adults with neurological conditions manifest not in isolated anatomical components but instead in the individual-environment system and are task-dependent. Optimization of function thus requires interprofessional care to promote participation in meaningful life areas within appropriate task and environmental contexts. Cotreatment guidelines (ie, the concurrent intervention of disciplines) were established by the physical therapy, occupational therapy, and speech-language and hearing professional organizations nearly 2 decades ago to facilitate seamless interprofessional care. Despite this, cotreatment between physical therapy and speech therapy remains limited. The purpose of this Perspective article is to encourage physical therapists and speech-language pathologists to increase interprofessional collaboration through cotreatment in the management of adults with neurological conditions. Evidence from pediatrics and basic motor control literature points toward reciprocal interactions between speech-language and mobility. We provide recommendations for clinical practice with an emphasis on the gains each discipline can provide the other. This Perspective is rooted in the International Classification of Functioning, Disability and Health model and ecological theory.

IMPACT

The goals of speech therapy and physical therapy are complementary and mutually supportive. Enhanced cotreatment, and collaboration more generally, between physical therapists and speech-language pathologists in the management of adults with neurological conditions can augment task-relevant conditions to improve function.

Efficacy of osteopathic manipulative treatment in patients with Parkinson's disease: a narrative review

CONTEXT

Parkinson's disease (PD) is a neurodegenerative disease that leads to impaired motor and non-motor function in patients. PD is non-curative and gradually reduces quality of life, leading patients to seek treatment for symptom management. Osteopathic manipulative treatment (OMT) applies the biomechanical, neurologic, circulatory, metabolic, and psychosocial models in approaching and treating the major symptomatology of PD patients.

OBJECTIVES

This article evaluates the literature published in the past 10 years analyzing evidence on OMT and its functional application on gait, balance, motor function, bradykinesia, and autonomic dysfunctions, and to identify promising avenues for further investigation.

METHODS

The authors obtained studies from the research databases MEDLINE/PubMed, ScienceDaily, and EBSCO, as well as the Journal of American Osteopathic Association's published archives. Searches were conducted in December 2020 utilizing the search phrases "OMM" (osteopathic manipulative medicine), "OMT," "osteopathic," "Parkinson Disease," "manual therapy," "physical therapy," "training," "autonomics," "gait," and "balance." Articles published between 2010 and 2021 including subjects with Parkinson's disease and the use of OMT or any other form of manual therapy were included. Five authors independently performed literature searches and methodically resolved any disagreements over article selection together.

RESULTS

There were a total of 10,064 hits, from which 53 articles were considered, and five articles were selected based on the criteria.

CONCLUSIONS

The progressive nature of PD places symptom management on the forefront of maintaining patients' quality of life. OMT has demonstrated the greatest efficacy on managing motor-related and neurologic symptoms and assists in treating the greater prevalence of somatic dysfunctions that arise from the disease. Research in this field remains limited and should be the target of future research.

Effects of robot-assisted gait training on postural instability in Parkinson's disease: a systematic review

INTRODUCTION

Postural instability is a cardinal feature of Parkinson's disease, together with rest tremor, rigidity and bradykinesia. It is a highly disabling symptom that becomes increasingly common with disease progression and represents a major source of reduced quality of life in patients with Parkinson's disease. Rehabilitation aims to enable patients with Parkinson's disease to maintain their maximum level of mobility, activity and independence. To date, a wide range of rehabilitation approaches has been employed to treat postural instability in Parkinson's disease, including robotic training. Our main aim was to conduct a systematic review of current literature about the effects of robot-assisted gait training on postural instability in patients with Parkinson's disease.

EVIDENCE ACQUISITION

A systematic search using the following MeSH terms "Parkinson disease," "postural balance," "robotics," "rehabilitation" AND string "robotics [mh]" OR "robot-assisted" OR "electromechanical" AND "rehabilitation [mh]" OR "training" AND "postural balance [mh]" was conducted on PubMed, Cochrane Library and Pedro electronic databases. Full text articles in English published up to December 2020 were included. Data about patient characteristics, robotic devices, treatment procedures and outcome measures were considered. Every included article got checked for quality. Level of evidence was defined for all studies.

EVIDENCE SYNTHESIS

Three authors independently extracted and verified data. In total, 18 articles (2 systematic reviews, 9 randomized controlled trials, 4 uncontrolled studies and 3 case series/case reports) were included. Both end-effector and exoskeleton devices were investigated as to robot-assisted gait training modalities. No clear relationship between treatment parameters and clinical conditions was observed. We found a high level of evidence about the effects of robot-assisted gait training on balance and freezing of gait in patients with Parkinson's disease.

CONCLUSIONS

This systematic review provides to the reader a complete overview of current literature and levels of evidence about the effects of robot-assisted gait training on postural instability issues (static and dynamic balance, freezing of gait, falls, confidence in activities of daily living and gait parameters related to balance skills) in patients with Parkinson's disease.

Plantarflexor strength, gait speed, and step length change in individuals with Parkinson's disease

Parkinson's disease affects the ability to walk often resulting in decreased independence and low quality of life. The purpose of this study was to examine differences in plantarflexor strength (PFS), gait speed, and step length in persons with Parkinson's disease (PwP) and healthy peers using clinical measures. A secondary purpose was to examine the relationship between these gait components across disease severity. The study was a convenience sample of 71 PwP and 25 community healthy peers. Outcome measures included 10-Meter Walk, step length, and Calf-Raise Senior Test. PwP were separated into mild and moderate impairment groups using the Movement Disorders Society United Parkinson's Disease Rating Scale Motor Subscale. Between group differences for gait speed (F2,93 = 24.560, P = 0.000), step length (F2,93 = 21.93, P = 0.000) and PFS (F2,93 = 19.49, P < 0.000) were observed. Post hoc testing determined a difference (P < 0.00) in gait speed, step length, and PFS testing between moderate impairment versus healthy peers and mild impairment. A difference (P = 0.045) in step length and a trend towards significance (P = 0.064) for PFS was found between healthy peers and mild impairment group. This study revealed that PwP with mild impairment also have significant changes in step length and trends toward plantarflexor weakness without a significant difference in gait speed. These early changes may warrant early assessment and intervention to prevent decline. This study may bring clinical focus onto the plantarflexor and step length for early comprehensive assessment and treatment of gait and mobility for PwP.

Frameworks for Parkinson's Disease Rehabilitation Addressing When, What, and How

PURPOSE OF REVIEW

This review summarizes the evidence on rehabilitation for people with Parkinson's disease, including when to refer, what rehabilitation professionals should address, and how to deliver rehabilitation care.

RECENT FINDINGS

Clinical practice guidelines support physical therapy, occupational therapy, and speech-language pathology for Parkinson's disease. However, integrating guidelines into practice may be difficult. Implementation studies take into account patient and clinician perspectives. Synthesizing guidelines with implementation research can improve local delivery. There is moderate to strong evidence supporting physical therapy, occupational therapy, and speech-language pathology soon after diagnosis and in response to functional deficits. We propose a framework of three pathways for rehabilitation care: (1) consultative proactive rehabilitation soon after diagnosis for assessment, treatment of early deficits, and promotion meaningful activities; (2) restorative rehabilitation to promote functional improvements; and (3) skilled maintenance rehabilitation for long-term monitoring of exercise, meaningful activities, safety, contractures, skin integrity, positioning, swallowing, and communication.

Unmet Needs of People With Parkinson's Disease and Their Caregivers During COVID-19-Related Confinement: An Explorative Secondary Data Analysis

Self-perceived unmet needs in people with typical and atypical parkinsonism (PwP) and their caregivers, support network, personalized ways to address self-perceived unmet needs during confinement, as well as the prevalence of self-reported COVID-19 related symptoms, confirmed SARS-CoV-2 infection, and self-reported COVID-19 related hospitalization in Luxembourg and the Greater Region were assessed. From 18th March to 10th April 2020, 679 PwP were contacted by phone. Data was collected in the form of a semi-structured interview. The thematic synthesis identified 25 themes where PwP need to be supported in order to cope with consequences of the pandemic, and to adapt their daily and health-related activities. The present work highlights that in the context of personalized medicine, depending on the individual needs of support of the patient the identified self-perceived unmet needs were addressed in various ways ranging from one-directed information over interaction up to proactive counseling and monitoring. Family and health professionals, but also other support systems were taking care of the unmet needs of PwP (e.g., shopping, picking-up medication, etc.) during the pandemic. 7/606 PwP (1.15%) reported COVID-19 related symptoms, 4/606 (0.66%) underwent a rRT-PCR-based diagnostic test and 2/606 (0.33%) were confirmed as SARS-CoV-2 positive. None of these PwP reported being hospitalized due to COVID-19. Our results will allow health professionals to expand their services in a meaningful way i.e., personalize their support in the identified themes and thus improve the healthcare of PwP in times of crisis.

Safinamide in neurological disorders and beyond: Evidence from preclinical and clinical studies

The discovery and development of safinamide, an alpha-aminoamide, has been a valuable addition to the existing clinical management of Parkinson's disease (PD). The journey of safinamide dates back to the year 1983, when an alpha-aminoamide called milacemide showed a weak anticonvulsant activity. Milacemide was then structurally modified to give rise to safinamide, which in turn produced robust anticonvulsant activity. The underlying mechanism behind this action of safinamide is attributed to the inhibition of voltage gated calcium and sodium channels. Moreover, owing to the importance of ion channels in maintaining neuronal circuitry and neurotransmitter release, numerous studies explored the potential of safinamide in neurological diseases including PD, stroke, multiple sclerosis and neuromuscular disorders such as Duchenne muscular dystrophy and non-dystrophic myotonias. Nevertheless, evidence from multiple preclinical studies suggested a potent, selective and reversible inhibitory activity of safinamide against monoamine oxidase (MAO)-B enzyme which is responsible for degrading dopamine, a neurotransmitter primarily implicated in the pathophysiology of PD. Therefore, clinical studies were conducted to assess safety and efficacy of safinamide in PD. Indeed, results from various Phase 3 clinical trials suggested strong evidence of safinamide as an add-on therapy in controlling the exacerbation of PD. This review presents a thorough developmental history of safinamide in PD and provides comprehensive insight into plausible mechanisms via which safinamide can be explored in other neurological and muscular diseases.

PasoDoble, a Proposed Dance/Music for People With Parkinson's Disease and Their Caregivers

Managing the heterogeneity of Parkinson's disease symptoms and its progressive nature demands strategies targeting the hallmark disrupted neurotransmission but also the comorbid derangements and bolstering neuroprotection and regeneration. Strong efforts are done to find disease-modifying strategies, since slowing disease progression is not enough to hamper its burden and some motor symptoms are resistant to dopamine-replacement therapy. The inclusion of non-pharmacological strategies can provide such a multitarget umbrella approach. The silent long-term biological process that precedes the clinical onset of disease is a challenge but also an opportunity to reinforce healthy lifestyle known to exert preventive/therapeutic effects. These non-pharmacological strategies are foreseen as able to reduce the prevalence and the global impact of long-term diseases demanding strong management of patient-caregiver quality of life. In this regard, European guidelines for Parkinson's disease recommend physical-related activities such as aerobic exercise and dancing known to improve functional mobility and balance in patients. Here, we propose “PasoDoble,” a novel dance/music patient-caregiver intervention with additional preventive value. The rationale is founded on evidence-based therapeutic benefits of dance/music therapy and the singular features of this widely extended Hispanic dance/music targeting motor symptoms, mood/cognition, and socialization: (i) As a dance, an easy and simple double-step pattern (back-and-forward and lateral movements) that evolves from a spontaneous individual dance to a partnered dancing, performed in social groups and involving dancing-figures of increasing complexity; (ii) “PasoDoble,” as a music that can be sung, has musical rhythmicity with high groove and familiarity that will help to synchronize the steps to the rhythm of music; (iii) Widely extended (Spain, Mexico, Puerto Rico, Colombia, and USA) and easy-to-learn for others. As a regular dancing “PasoDoble” can improve and preserve function, mood and socialization, as an intervention the method is structured to improve gait and balance; facilitate movement, reaching and grasping; muscle power and joint mobility; reduce of risk of falls, and increase of aerobic capacity. Finally, this easy-to-implement into patient care and free-living environments (elderly social centers, home care) rehabilitation programs can promote positive emotions and self-esteem, with added general improvement of social attachment and recognition, thus improving the quality of life of patient-caregiver.

Role of Genes and Treatments for Parkinson’s Disease

Parkinson’s Disease (PD) is a complex neurodegenerative disorder that mainly results due to the loss of dopaminergic neurons in the substantia nigra of the midbrain. It is well known that dopamine is synthesized in substantia nigra and is transported to the striatumvianigrostriatal tract. Besides the sporadic forms of PD, there are also familial cases of PD and number of genes (both autosomal dominant as well as recessive) are responsible for PD. There is no permanent cure for PD and to date, L-dopa therapy is considered to be the best option besides having dopamine agonists. In the present review, we have described the genes responsible for PD, the role of dopamine, and treatment strategies adopted for controlling the progression of PD in humans.

Efficacy of Occupational Therapy Interventions on Quality of Life in Patients with Parkinson's Disease: A Systematic Review and Meta-Analysis

Objective

To review studies assessing the efficacy of occupational therapy interventions on quality of life in patients with Parkinson's disease.

Method

We followed the international guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Databases (PubMed, Physiotherapy Evidence Database, OTsekeer, Scopus, Cinhal, and Web of Science) were searched to identify randomized controlled trials of occupational therapy interventions in patients with Parkinson's disease up to 2019 and with no restriction on language. The primary outcome of the meta-analysis was the evaluation of quality of life following occupational therapy interventions. Because of the heterogeneity of the studies, we examined the data by using a random effect model.

Results

We identified 15 randomized controlled trials that met the inclusion criteria, and 4 of these were included in the meta-analysis. Studies with a follow-up of 2 to 3 months showed that occupational therapy interventions significantly improved the quality of life in patients with Parkinson's disease, with a mean difference of -2.08 (95% confidence interval, -2.52 to -1.64; P < 0.00001). Studies reporting a longer follow-up (6-12 months) also showed that occupational therapy interventions improved the quality of life, with a mean difference of -2.56 (95% confidence interval, -3.52 to -1.61; P < 0.00001).

Conclusion

Different occupational therapy interventions may be effective in improving the quality of life in patients with Parkinson's disease. However, because of the limited number of studies available, the strength of the evidence should be considered moderate.
