A Meta-Analysis on the Efficacy of Tai Chi in Patients with Parkinson's Disease between 2008 and 2014

Unconventional exercises for motor function in Parkinson's disease: an umbrella review of meta-analyses

BACKGROUND

Unconventional exercises were initially used in the clinical treatment of Parkinson's disease (PD). However, clarity regarding their efficacy and credibility in clinical settings is lacking.

OBJECTIVES

To summarise and evaluate the effectiveness of various unconventional exercises on motor function in people with PD (PwPD).

METHODS

We searched multiple databases up to 31 July 2024, for relevant randomised controlled trials to identify associations between nontraditional exercise and PD outcome evaluations and meta-analyses. The effect sizes were recalculated as mean difference or standardised mean difference with 95% confidence interval and prediction interval. Systematic review quality was assessed using A MeaSurement Tool to Assess systematic Reviews 2, and the certainty of the evidence was assessed using the Grading of Recommendations, Assessments, Developments, and Evaluations system.

RESULTS

We included 39 associations from nine meta-analyses. Outcomes of PD motor function, including motor impairment, balance, walking and endurance, were examined. Of the 39 associations, 25 were statistically significant, and one was supported by high-certainty evidence. Robotic-assisted gait training improved motor function compared with conventional interventions. Nine associations of significance were supported by moderate-certainty evidence. Baduanjin, exergaming rehabilitation and dancing also showed significant improvements in motor function.

CONCLUSIONS

Unconventional exercises demonstrated advantages for PwPD compared to conventional exercises and passive interventions. However, these results should be cautiously interpreted due to variations across studies and differing certainty levels. More high-quality randomised controlled trials are needed to strengthen the evidence base for these interventions in clinical application.

Physical exercise and its effects on people with Parkinson's disease: Umbrella review

INTRODUCTION

Parkinson's disease is neurodegenerative, complex and progressive, manifesting in a slow and irreversible way. Physical exercise has been proposed as therapeutic alternative to people with Parkinson´s disease.

OBJECTIVE

To synthesize knowledge about the effects of physical exercise on people with Parkinson´s Disease as presented by published systematic reviews.

METHODS

Nine electronic databases and two grey literature databases were searched for systematic reviews reporting the effects of physical exercises on people with Parkinson´s Disease. Searches involved a two-phase process, by, at least, two independent reviewers. Methodological quality of the included systematic reviews was assessed using AMSTAR-2.

RESULTS

From 2,122 systematic reviews, 139 were included. Motor outcomes were assessed in 91% of the studies, with balance being the most studied. Non-motor outcomes were assessed in 68% of the studies, with emphasis on quality of life. Physical exercises were classified into five categories: aerobic exercises, strength, combined, sensorimotor activities and other activity protocols. Findings of the systematic reviews suggest that all exercise categories can be prescribed to improve balance and mobility, while combined exercises, strength, and specific activities improve both motor and non-motor outcomes, and aerobic exercise and sensorimotor activities improve motor outcomes.

CONCLUSION

Current evidence from systematic reviews suggests that physical exercises impacts both motor and non-motor outcomes in people with Parkinson´s Disease. Limits in evidence provided by the systematic reviews were related to methodological issues and to the description of the interventions and must be considered to improve decision-making and clinical application.

The role of exercise in Parkinson's Disease

Parkinson's disease (PD) is a progressive widespread neurodegenerative disorder affecting the brain. It is characterized by dopaminergic neuron degeneration in the substantia nigra pars compacta (SNpc). Current therapeutic options ease the symptoms of PD; however, they have multiple undesirable effects and do not slow the disease progression. Exercise by itself has many positive impacts on general health. In this review, the positive impact of different forms of exercise were found to improve motor and non-motor symptoms in PD. Exercise effects is mediate by multiple mechanisms, including the upregulation of brain-derived neurotrophic factor, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor, and autophagy regulating proteins; and downregulates proinflammatory cytokines. In this review, the significance of exercise in PD, as well as in the prevention and maintenance of the disease was discussed. Many questions are left unanswered in this manuscript, including potential genetic factors underlying response to exercise. Therefore, further high-quality studies on humans are needed.

Benefits of Tai Chi Quan on neurodegenerative diseases: A systematic review

BACKGROUND

Neurodegenerative diseases have become an important concern with the accelerated aging process. Tai Chi Quan (TCQ) has positive benefits for brain health and chronic diseases. The aim of this study was to summarize the protective effects of TCQ for motor function, cognition, quality of life, and mood in patients with neurodegenerative diseases.

METHODS

A systematic search was conducted via PubMed database and the Web of Science core collection database until August 20, 2021. The available English systematic reviews, meta-analyses, and clinical trials were included. Two reviewers completed the screening and assessment process independently.

RESULTS

A total of 28 studies on Parkinson's disease, 21 on cognitive impairment, and 9 on multiple sclerosis met the included criteria. The study found that TCQ remarkably improved general motor function and balance, and prevented falls for Parkinson's disease. TCQ significantly improved global cognitive function for cognitive impairment. TCQ was likely safe and beneficial for multiple sclerosis as result of heterogeneous outcomes and small samples.

CONCLUSION

TCQ exercise can effectively improve the motor function, global cognitive function, and falls in patients with neurodegenerative diseases. However, the positive effects of TCQ on the quality of life and mood of patients with neurodegenerative diseases need further evidence.

The Efficacy of Tai Chi and Stretching Exercises Based on a Smartphone Application for Patients With Parkinson's Disease: A Protocol for a Randomized Controlled Trial

Introduction: Parkinson's disease (PD) is a common neurodegenerative disease that seriously impairs patients' quality of life, and increases the burden of patients and caregivers. Both drugs and exercise can alleviate its motor and non-motor symptoms, improving the quality of life for PD patients. Telehealth, an increasingly popular tool, makes rehabilitation accessible at home, overcoming the inconvenience of traffic and scheduling. Care-PD is a phone application designed for rehabilitation training, which provides Tai Chi and stretching exercises through tutorial videos as well as an online evaluation system. In this protocol, we will explore the efficacy of Tai Chi and stretching exercises as a PD rehabilitation therapy based on the smartphone application Care-PD.

Methods and Analysis: A double-blind, parallel randomized controlled trial will be conducted in this study. The recruitment, intervention, and evaluation processes will be implemented through the Care-PD application. Persons with PD will fill out questionnaires on Activities of Daily Living (ADL), upload the latest case report, and sign the informed consent form in the application. Afterward, doctors and researchers will screen and enroll 180 participants who will be randomly (1:1:1) assigned to Tai Chi group, stretching exercises group, or control group. The subjects will participate in a 1-h exercise session three times per week for 12 weeks, ending with another 4 weeks of follow-up study. Each exercise session includes 10 min of warm-up, 45 min of exercise, and 5 min of cool-down. The primary outcomes are Motor Aspects of Experiences of Daily Living and the 39-item Parkinson's disease Questionnaire. The secondary outcomes include the 9-item Wearing-Off Questionnaire, the Freezing of Gait Questionnaire, the Caregiver Strain Index, Non-motor Experiences of Daily Living, ADL, and Morse Fall Scale. All assessments will be performed at baseline, week 12 and 16.

Discussion: Care-PD integrates subject recruitment, intervention, and evaluation, providing a new perspective on clinical rehabilitation for persons with PD. This study will evaluate the efficacy of Tai Chi and stretching exercises on patients' quality of life and disease progression based on a smartphone application. We aim to provide a new rehabilitation training platform for persons with PD.

Ethics and Dissemination: This study was approved by the Scientific Research Ethics Committee (102772020RT132) of Shanghai University of Sport. Data collection begins after the approval of the ethics committee. The participants must sign an informed consent form before enrollment. The results will be published in relevant journals, seminars, and be disseminated among rehabilitation practitioners and patients with PD.

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.

I Feel Like I Am Flying and Full of Life: Contemporary Dance for Parkinson's Patients

Parkinson’s is a neurodegenerative disease characterized by motor and non-motor symptoms which are strongly associated with patients’ quality of life, affecting social skills and support. It strikes not only the motor abilities but may harm cognitive and emotional functioning. For the past 15 years, contemporary dance has been employed as an intervention to help people diagnosed with Parkinson’s disease cope physically and mentally by way of motor, vestibular, and sensory stimulation as well as social interaction. In this study we aimed to examine psychological flexibility, creative self-efficacy and quality of life of Parkinson’s patients participating in contemporary dance sessions. To obtain this goal we conducted a cross-sectional comparative study of 50 Parkinson’s patients aged 50–87 years, half of which had been participating for at least 3 months once a week, in contemporary dance classes, and the matched controls participated in a verbal support group. Study participants completed questionnaires after participating in a dance class (Intervention) or in a support group (control). Participants in the intervention group were also asked to answer three open-ended questions that examined the experience of participating in contemporary dance classes. We found that psychological flexibility and quality of life were significantly higher in the dance class participants. Participants reported positive changes that occur in their overall feeling and quality of life following their participation in dance classes. Since PD patients’ experiences are deeply embedded in the body, it is significant to explore the use of movement in treatment. The importance of the study is in its potential to highlight the relationship between psychological flexibility and quality of life and to increase awareness of clinicians treating Parkinson’s patients to the importance of incorporating dance as an inherent part of a multidisciplinary team effort.

Effects of a High-Intensity Progressive-Cycle Program on Quality of Life and Motor Symptomatology in a Parkinson's Disease Population: A Pilot Randomized Controlled Trial

The benefits of aerobic exercise in persons with Parkinson's disease (PD) have been widely studied. Recent studies support the use of high-intensity aerobic exercise to improve oxidative stress values and functional performance in PD patients. The aim of this study is ascertain whether high-intensity aerobic training with lower extremity cycle ergometers and balance training can improve motor symptoms and quality of life in a PD population of Hoehn and Yahr disability score 1-3. The intervention took place in rehabilitation centers in secondary care. A pilot randomized controlled trial was carried out with 14 outpatients participated in the 8-week study. They were composed of a control group (CG; n = 7) that followed a balance protocol and an experimental group (EG; n = 7) that performed high-intensity (70% heart rate reserve) aerobic workout using a lower extremity cycle ergometer and a balance protocol once a week. The primary outcome measures included the 8-Foot Up-and-Go test, 6-Minute Walk test, 2-Minute Step test, Parkinson's Disease Questionnaire (PDQ39), Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and Tinetti test. Significant improvements in the PDQ39 (F_1.23 = 3.102; sig = 0.036), the MDS-UPDRS III (F_1.23 = 4.723; sig = 0.033), and MDS-UPDRS Total (F_1.23 = 4.117; sig = 0.047) were observed in the EG as against the CG. After taking into account the number of subjects in each group, the results suggest that the PD population can withstand high-intensity aerobic workouts with a lower extremity cycle ergometer. This exercise is a beneficial therapy for them because it reduces motor symptoms of the disease and furthermore increases and improves patient's quality of life.

What and How Can Physical Activity Prevention Function on Parkinson's Disease?

Aim

This study was aimed at investigating the effects and molecular mechanisms of physical activity intervention on Parkinson's disease (PD) and providing theoretical guidance for the prevention and treatment of PD.

Methods

Four electronic databases up to December 2019 were searched (PubMed, Springer, Elsevier, and Wiley database), 176 articles were selected. Literature data were analyzed by the logic analysis method.

Results

(1) Risk factors of PD include dairy products, pesticides, traumatic brain injury, and obesity. Protective factors include alcohol, tobacco, coffee, black tea, and physical activity. (2) Physical activity can reduce the risk and improve symptoms of PD and the beneficial forms of physical activity, including running, dancing, traditional Chinese martial arts, yoga, and weight training. (3) Different forms of physical activity alleviate the symptoms of PD through different mechanisms, including reducing the accumulation of α-syn protein, inflammation, and oxidative stress, while enhancing BDNF activity, nerve regeneration, and mitochondrial function.

Conclusion

Physical activity has a positive impact on the prevention and treatment of PD. Illustrating the molecular mechanism of physical activity-induced protective effect on PD is an urgent need for improving the efficacy of PD therapy regimens in the future.

Tai Chi versus routine exercise in patients with early- or mild-stage Parkinson's disease: a retrospective cohort analysis

Parkinson's disease cannot be cured but symptoms can be improved by making use of physical therapy. The objective of the study was to compare the effect of routine exercises and Tai Chi on physical and clinical performance in elderly people suffering from Parkinson's disease. Data from interviews, physical and clinical performance, and levodopa consumption of 500 patients with confirmed Parkinson's disease (severity level I to III) were collected and analyzed. Participants who received 80 min/day Tai Chi 3 times/week for 2 months were included in the Tai Chi (TC) group (n=250) and those who received 90 min/day routine exercise 3 times/week for 2 months were included in routine exercise (RE) group (n=250). Timed up-and-go, 50-foot speed walk, and functional reach were improved by Tai Chi and routine exercise (P<0.05 for all) but intensities of Tai Chi for improvement of such parameters was higher than routine exercise. Incidence of falls was decreased by both physical therapies (P<0.05 for all) but more for the TC group (P<0.0001, q=38.512). In the TC group, at the end of follow-up, 22 (9%) patients were successful in withdrawal of levodopa treatment. Also, the dose of levodopa was decreased in patients of the TC group who had to continue levodopa. Tai Chi had the potential to slow down the progression of symptoms of Parkinson's disease and delayed the introduction of levodopa (level of evidence: III).

Parameters of Surface Electromyogram Suggest That Dry Immersion Relieves Motor Symptoms in Patients With Parkinsonism

Dry immersion (DI) is acknowledged as a reliable space flight analog condition. At DI, subject is immersed in water being wrapped in a waterproof film to imitate microgravity (μG). Microgravity is known to decrease muscle tone due to deprivation of the sensory stimuli that activate the reflexes that keep up the muscle tone. In contrary, parkinsonian patients are characterized by elevated muscle tone, or rigidity, along with rest tremor and akinesia. We hypothesized that DI can diminish the elevated muscle tone and/or the tremor in parkinsonian patients. Fourteen patients with Parkinson's disease (PD, 10 males, 4 females, 47-73 years) and 5 patients with vascular parkinsonism (VP, 1 male, 4 females, 65-72 years) participated in the study. To evaluate the effect of DI on muscles' functioning, we compared parameters of surface electromyogram (sEMG) measured before and after a single 45-min long immersion session. The sEMG recordings were made from the biceps brachii muscle, bilaterally. Each recording was repeated with the following loading conditions: with arms hanging freely down, and with 0, 1, and 2 kg loading on each hand with elbows flexed to 90°. The sEMG parameters comprised of amplitude, median frequency, time of decay of mutual information, sample entropy, correlation dimension, recurrence rate, and determinism of sEMG. These parameters have earlier been proved to be sensitive to PD severity. We used the Wilcoxon test to decide which parameters were statistically significantly different before and after the dry immersion. Accepting the p < 0.05 significance level, amplitude, time of decay of mutual information, recurrence rate, and determinism tended to decrease, while median frequency and sample entropy of sEMG tended to increase after the DI. The most statistically significant change was for the determinism of sEMG from the left biceps with 1 kg loading, which decreased for 84% of the patients. The results suggest that DI can promptly relieve motor symptoms of parkinsonism. We conclude that DI has strong potential as a rehabilitation method for parkinsonian patients.

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.

Karate and Dance Training to Improve Balance and Stabilize Mood in Patients with Parkinson's Disease: A Feasibility Study

The present pilot study investigated the effect of karate (according to the rules of the German Karate Federation) and dance training compared to an inactive control group in patients with Parkinson's disease (PD). 65 patients were recruited. At the end, 37 patients completed the post-test. From those 37 patients, 16 had chosen the karate training, 9 the dance training and 12 the waiting control group. Before and after the whole training phase cognitive performance, emotional well-being and balance were measured. The results showed that both, karate and dance training groups, improved balance. Furthermore, the mood dropped only in the waiting control group receiving no training at all, whereas it remained stable in patients who attended the karate and dance group. The training adherence was higher in the karate than the dance group indicating a high acceptability in PD patients for karate. In sum, karate can have the same positive effects as dance for PD patients. Further studies with larger samples and more rigorous methodologies are required to investigate the reported effects in more detail.

Meditative Movement, Energetic, and Physical Analyses of Three Qigong Exercises: Unification of Eastern and Western Mechanistic Exercise Theory

Qigong is the meditative movement and therapeutic exercise of Eastern medicine. A growing body of evidence is validating its health benefits leading to mechanistic questions of how it works. The purpose of this article is to explore mechanisms of action related to Qigong, with the intent of unifying Eastern and Western exercise theory and to present a model for Qigong exercise analysis. Three exercises from a standardized Qigong form: ‘Plucking the Stars’, ‘Lotus Leaves Rustle in the Wind’, and ‘Pacing Forwards and Backwards’ were selected for meditative, energetic, and physical analyses. Meditative aspects include relaxation response, interoception and exteroception. Energetic aspects include stimulation of meridians through mental intent, acupressure, and self-massage. Physical aspects include flexibility, strength, articular stimulation, neuro-integration, respiratory effect, fascial stretch, visceral massage, balance challenge CranioSacral pump, lymphatic and venous return and glandular stimulation, and physiologic response to relaxation. Knowledge of mechanisms of action for specific Qigong exercises can guide operational definition of Qigong, selection of outcomes assessment in future research, inform prescriptive practice addressing clinical health issues, and advance adoption of Qigong practice within integrative health care. The model of analysis demonstrated in this discussion may assist in these endeavors.

Utilization of rehabilitation therapy services in Parkinson disease in the United States

OBJECTIVE

To examine rehabilitation therapy utilization for Parkinson disease (PD).

METHODS

We identified 174,643 Medicare beneficiaries with a diagnosis of PD in 2007 and followed them through 2009. The main outcome measures were annual receipt of physical therapy (PT), occupational therapy (OT), or speech therapy (ST).

RESULTS

Outpatient rehabilitation fee-for-service use was low. In 2007, only 14.2% of individuals with PD had claims for PT or OT, and 14.6% for ST. Asian Americans were the highest users of PT/OT (18.4%) and ST (18.4%), followed by Caucasians (PT/OT 14.4%, ST 14.8%). African Americans had the lowest utilization (PT/OT 7.8%, ST 8.2%). Using logistic regression models that accounted for repeated measures, we found that African American patients (adjusted odds ratio [AOR] 0.63 for PT/OT, AOR 0.63 for ST) and Hispanic patients (AOR 0.97 for PT/OT, AOR 0.91 for ST) were less likely to have received therapies compared to Caucasian patients. Patients with PD with at least one neurologist visit per year were 43% more likely to have a claim for PT evaluation as compared to patients without neurologist care (AOR 1.43, 1.30-1.48), and this relationship was similar for OT evaluation, PT/OT treatment, and ST. Geographically, Western states had the greatest use of rehabilitation therapies, but provider supply did not correlate with utilization.

CONCLUSIONS

This claims-based analysis suggests that rehabilitation therapy utilization among older patients with PD in the United States is lower than reported for countries with comparable health care infrastructure. Neurologist care is associated with rehabilitation therapy use; provider supply is not.

The Effects of Group-Based versus Individual-Based Tai Chi Training on Nonmotor Symptoms in Patients with Mild to Moderate Parkinson's Disease: A Randomized Controlled Pilot Trial

Objective

To compare the effects of group-based and individual-based Tai Chi training on nonmotor symptoms in patients with mild to moderate Parkinson's disease.

Design

Randomized controlled pilot study.

Methods

36 community-dwelling patients with Parkinson's disease (PD) were randomly assigned to either group-based training group (n = 19) or individual-based group (n = 17). Both groups received same content of Tai Chi training 3 times a week for 13 weeks. Participants were also asked to perform home exercises daily. The Non-Motor Symptoms Scale was used to assess global nonmotor symptoms change. Sleep quality, depression, and cognition were evaluated by Parkinson's Disease Sleep Scale, Hamilton Depression Scale, and Beijing version-Montreal Cognitive Assessment, respectively. Home exercise compliance was recorded.

Results

There was no significant difference between two groups at baseline. After 13 weeks, there were no statistical significance between two groups. However, the within-group effect was different. Participants in group-based and individual-based groups showed a significant improvement on global nonmotor symptoms (P < 0.001, P = 0.004) and sleep (P < 0.001, P < 0.001). But only group-based training patients presented a significant improvement in cognitive impairment compared with baseline (P = 0.002, P − 0.116). For depression, no group gained a significant improvement(P = 0.123, P = 0.170). Group-based participants had a higher home-exercise compliance rate (HeCR) than individual-based participants did (P = 0.019), and HeCR showed a moderate correlation with MoCA-BJ and NMSS scores changes in this study.

Conclusion

Group-based Tai Chi training is considered to be a more effective and a more labor-saving method in the clinical settings, and patients tend to have a higher compliance rate in their home exercise program. This study is registered with ChiCTR-IPR-17010388.

Tai chi for health benefits in patients with multiple sclerosis: A systematic review

The aim of this systematic review was to evaluate the existing evidence on the effectiveness and safety of Tai chi, which is critical to provide guidelines for clinicians to improve symptomatic management in patients with multiple sclerosis (MS). After performing electronic and manual searches of many sources, ten relevant peer-reviewed studies that met the inclusion criteria were retrieved. The existing evidence supports the effectiveness of Tai chi on improving quality of life (QOL) and functional balance in MS patients. A small number of these studies also reported the positive effect of Tai chi on flexibility, leg strength, gait, and pain. The effect of Tai chi on fatigue is inconsistent across studies. Although the findings demonstrate beneficial effects on improving outcome measures, especially for functional balance and QOL improvements, a conclusive claim should be made carefully for reasons such as methodological flaws, small sample size, lack of specific-disease instruments, unclear description of Tai chi protocol, unreported safety of Tai chi, and insufficient follow-up as documented by the existing literature. Future research should recruit a larger number of participants and utilize the experimental design with a long-term follow-up to ascertain the benefits of Tai chi for MS patients.

[Other care in Parkinson's disease: Psychological, rehabilitation, therapeutic education and new technologies]

Diagnosis of Parkinson's disease (PD) is often traumatic. It is then important to organize this announcement in order to support the patient in this major step of his care course. Anxiety and depression are present in about 50% of PD patients. Besides pharmacological treatment, cognitive-behavioral therapy induces improvement in anxio-depressive symptoms. We have to promote physical activity for PD patients, from the beginning of the disease, because it prevents from deconditioning, improves motor and non-motor symptoms, quality of life, and decreases loneliness. Rehabilitation may be also proposed (physiotherapy, speech therapy, occupational therapy). But there is no specific recommendation in PD, and usual activities can be proposed. Therapeutic education is an answer for PD patients who need to know and understand their disease and treatment. Organization of therapeutic education is different depending of the teams: group workshop and/or individual sessions, conduct by doctors or paramedical staff (nurse, physiotherapist, psychologist…). Therapeutic education programs are always evolving. It will soon be proposed therapeutic education for care partners, and some patients may join therapeutic education staff.

Bienfaits du tai-chi sur la santé

Objectif

Résumer les données probantes sur les bienfaits du tai-chi sur la santé.

Sources d’information

Une revue de la littérature sur les bienfaits du tai-chi sur 25 affections différentes, de même que sur la santé en général et sur la forme physique, a été effectuée afin d’actualiser une revue des revues systématiques effectuée en 2014. Les revues systématiques et les essais cliniques récents ont été évalués et organisés en 5 groupes : données excellentes, bonnes, acceptables ou préliminaires, étayant un bienfait ou n’étayant aucun bienfait direct.

Message principal

Au cours des 45 dernières années, plus de 500 essais et 120 revues systématiques ont été publiés sur les bienfaits du tai-chi sur la santé. Les revues systématiques sur le tai-chi pour différentes affections ont donné lieu à d’excellentes données étayant un bienfait pour la prévention des chutes, l’arthrose, la maladie de Parkinson, la réadaptation dans les cas de maladie pulmonaire obstructive chronique et l’amélioration de la capacité cognitive chez les personnes âgées. Il existe de bonnes données étayant un bienfait pour la dépression, la réadaptation cardiaque et après un AVC et la démence. Les données étayant un bienfait pour l’amélioration de la qualité de vie des patients atteints de cancer, de fibromyalgie, d’hypertension et d’ostéoporose sont acceptables. Les données actuelles étayent l’absence d’un bienfait direct pour le diabète, la polyarthrite rhumatoïde ou l’insuffisance cardiaque chronique. Les revues systématiques portant sur les bienfaits sur la santé en général et la forme physique font état d’excellentes données étayant un bienfait pour l’amélioration de l’équilibre et de la capacité aérobique chez les personnes en mauvaise forme physique. Les données étayant une plus grande force dans les membres inférieurs sont bonnes. Les données étayant une amélioration du bien-être et du sommeil sont acceptables. Aucune étude n’a révélé que le tai-chi aggravait une affection. Une récente revue systématique sur l’innocuité du tai-chi a révélé que les événements indésirables étaient habituellement mineurs et principalement de nature musculosquelettique; aucun événement indésirable grave lié au tai-chi n’a été rapporté.

Conclusion

Il existe d’abondantes données étayant les effets du tai-chi sur la santé et la forme physique. En s’appuyant sur ces données, les médecins peuvent maintenant faire des recommandations éclairées à leurs patients, en précisant que le tai-chi fait toujours l’objet de recherches. Aussi, toute affection clinique doit faire l’objet d’un suivi médical continu.

Health benefits of tai chi: What is the evidence?

OBJECTIVE

To summarize the evidence on the health benefits of tai chi.

SOURCES OF INFORMATION

A literature review was conducted on the benefits of tai chi for 25 specific conditions, as well as for general health and fitness, to update a 2014 review of systematic reviews. Systematic reviews and recent clinical trials were assessed and organized into 5 different groups: evidence of benefit as excellent, good, fair, or preliminary, or evidence of no direct benefit.

MAIN MESSAGE

During the past 45 years more than 500 trials and 120 systematic reviews have been published on the health benefits of tai chi. Systematic reviews of tai chi for specific conditions indicate excellent evidence of benefit for preventing falls, osteoarthritis, Parkinson disease, rehabilitation for chronic obstructive pulmonary disease, and improving cognitive capacity in older adults. There is good evidence of benefit for depression, cardiac and stroke rehabilitation, and dementia. There is fair evidence of benefit for improving quality of life for cancer patients, fibromyalgia, hypertension, and osteoporosis. Current evidence indicates no direct benefit for diabetes, rheumatoid arthritis, or chronic heart failure. Systematic reviews of general health and fitness benefits show excellent evidence of benefit for improving balance and aerobic capacity in those with poor fitness. There is good evidence for increased strength in the lower limbs. There is fair evidence for increased well-being and improved sleep. There were no studies that found tai chi worsened a condition. A recent systematic review on the safety of tai chi found adverse events were typically minor and primarily musculoskeletal; no intervention-related serious adverse events have been reported.

CONCLUSION

There is abundant evidence on the health and fitness effects of tai chi. Based on this, physicians can now offer evidence-based recommendations to their patients, noting that tai chi is still an area of active research, and patients should continue to receive medical follow-up for any clinical conditions.

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.
