ABSTRACT Gait dysfunction and postural instability are two debilitating symptoms in persons with Parkinson's disease (PD). Tai Chi exercise has recently gained attention as an attractive intervention for persons with PD because of its known potential to reduce falls and improve postural control, walking abilities, and safety at a low cost. The purpose of this report is to investigate the effect of Tai Chi exercise on dynamic postural control during gait initiation and gait performance in persons with idiopathic PD, and to determine whether these benefits could be replicated in two different environments, as complementary projects. In these two separate projects, a total of 45 participants with PD were randomly assigned to either a Tai Chi group or a control group. The Tai Chi groups in both projects completed a 16-week Tai Chi exercise session, while the control groups consisted of either a placebo (i.e., Qi-Gong) or non-exercise group. Tai Chi did not significantly improve Unified Parkinson's Disease Rating Scale Part III score, selected gait initiation parameters or gait performance in either project. Combined results from both projects suggest that 16 weeks of class-based Tai Chi were ineffective in improving either gait initiation, gait performance, or reducing parkinsonian disability in this subset of persons with PD. Thus the use of short-term Tai Chi exercise should require further study before being considered a valuable therapeutic intervention for these domains in PD.

    ABSTRACT: A substantial number of individuals with Parkinson's disease exhibit debilitating non-motor symptoms that decrease quality of life. To date, few treatment options exist for the non-motor symptomatology related to Parkinson's disease. The goal of this pilot investigation was to determine the effects of Tai Chi exercise on the non-motor symptomology in Parkinson's disease. Twenty-one individuals with Parkinson's disease were enrolled in a Tai Chi intervention (n=15) or a noncontact control group (n=6). Participants assigned to Tai Chi participated in 60-minute Tai Chi sessions three times per week, for 16 weeks. Pre and post measures included indices of cognitive-executive function including visuomotor tracking and attention, selective attention, working memory, inhibition, processing speed and task switching. Additionally, all participants were evaluated on the Parkinson's disease Questionnaire-39 and Tinetti's Falls Efficacy Scale. Results indicated that the Tai Chi training group had significantly better scores following the intervention than the control group on the Parkinson's disease Questionnaire-39 total score as well as the emotional well-being sub score. Trends for improvement were noted for the Tai Chi group on Digits Backwards, Tinetti's Falls Efficacy Scale, and the activities of daily living and communication sub scores of the Parkinson's disease Questionnaire-39. This research provides initial data that supports future studies to definitively establish efficacy of Tai Chi to improve non-motor features of Parkinson's disease.

    ABSTRACT: Objective/Background This study aims to review the current evidence on the effectiveness of Tai Chi exercise in individuals with Parkinson's disease (PD) in the past 10 years. Methods A systematic review of studies published in English from 2003 to 2013, retrieved from three electronic databases—MEDLINE, Cumulative Index to Nursing and Allied Health Literature, and ScienceDirect—was performed. The review selected only those studies that investigated the effects of Tai Chi exercise on individuals with PD and had a full-length publication. Methodological qualities of the randomized control trials were appraised based on the modified Jadad scale. Results Of the 702 articles, eight publications, including four randomized controlled trials, two single-arm intervention studies, and two case reports, were reviewed. Results of this review show that there is an inconsistency of strong empirical evidence to support the efficacy of Tai Chi exercise in the PD population. Furthermore, this review reveals that there is a lack of scientific rigor in the experimental designs of the trials conducted to examine the effects of Tai Chi intervention on the PD population. Conclusion Because of the small sample and inconclusive results, this review cannot provide a firm conclusion to support or refute the effectiveness of Tai Chi in improving motor or nonmotor performance in patients with PD. Further research is required to investigate whether there are specific benefits of Tai Chi for people with PD in these areas and future review should include non-English studies, which examine the use of Tai Chi with this type of population.

    ABSTRACT: At least 40 % of patients with Parkinson's disease (PD) use one or more forms of alternative therapy (AT) to complement standard treatments. This article reviews the commonest forms of AT for PD, including acupuncture, tai chi, yoga, mindfulness, massage, herbal medicine, and cannabis. We discuss the current evidence for the clinical efficacy of each AT and discuss potential mechanisms, including those suggested by animal and human studies. With a few notable exceptions, none of the treatments examined were investigated rigorously enough to draw definitive conclusions about efficacy or mechanism. Tai chi, acupuncture, Mucuna pruriens, cannabinoids, and music therapy have all been proposed to work through specific mechanisms, although current evidence is insufficient to support or refute these claims, with the possible exception of Mucuna pruriens (which contains levodopa). It is likely that most ATs predominantly treat PD patients through general mechanisms, including placebo effects, stress reduction, and improved mood and sleep, and AT may provide patients with a greater locus of control regarding their illness.

Questions & Answers about this publication

  • Pao Yen asked a question in Caffeine:
    Taichi that was developed before and after 1956 are totally different things. Which one was used in your experiment?
    A recent study in 2013 found that taichi developed after 1956 is just low-impact cardiovascular exercises benefitted muscles and muscle control mostly. Whereas taichi created before 1956 had self-healing properties from head to toe because their movements are slow enough to cheat the brain into thinking they are not moving. By using deep breathing and continuous leg movements, oxygenated blood can be squeezed to all capillary beds in the brain (and other internal organs and tissues) by moderate elevation of heart rate and increase of stroke volume. It then allows brain cells to produce new cells with normal DNA in a longer time period. Details can be found in my hypothesis called "Pao's Law of Exercise", which can be applied to a certain extend to other medical treatments, sports and the use of stimulants.
