Effects of a video guided T'ai Chi group intervention on center of balance and falls efficacy: a pilot study.

This pilot study evaluated effects of a video-guided T'ai Chi group intervention on center of balance (COB) and falls efficacy, using a one arm, pre/post design. Thirty-two participants began the study, 17 completed pre- and post-testing and 15 were lost to follow-up. Outcomes were compared for the 17 participants who completed pre- and post-testing and subgroups based on session attendance. Irrespective of session attendance, participant COB scores improved. There was a significant negative correlation between number of sessions attended and pre and post scores on the fall efficacy (fear of falling) measure, indicating those with higher fear of falling were less likely to complete the study. Older participants were also less likely to continue participation. Findings indicate potential benefits of T'ai Chi in improving COB (a fall risk factor) among community-dwelling older adults. However, those with greater potential benefit (higher fear scores, older participants) were less likely to continue participation.

The effects of t'ai chi on muscle activity, pain, and balance in females in their 20s with acute low back pain.

[Purpose] This study was conducted in order to examine the effects of t'ai chi on females in their 20s with acute low back pain. The subjects were 30 females in their 20s with acute low back pain. [Subjects and Methods] They were equally and randomly divided into a t'ai chi group and a stretching group. The intervention was applied three times per week, one hour each time, for a total of eight weeks. During the one hour, the subjects conducted warm-up exercises for 10 min, primary exercises for 40 min, and cool-down exercises for 10 min. In order to examine changes in low back pain in the patients according to the intervention method, muscle activity, pain, and balance elements (left and right side movement distance, forward and backward movement distance) were measured. [Results] Muscle activity and the visual analog scale score significantly decreased in both the t'ai chi group and the stretching group. Regarding changes in balance elements, the t'ai chi group's left and right side movement distance decreased, which was statistically significant. However, the t'ai chi group's forward and backward movement distance and the stretching group's forward and backward movement distance and left and right side movement distance did not change. [Conclusion] According to the results of this study, t'ai chi is considered an appropriate exercise program to reduce acute low back pain in females in their 20s. This is because when compared with stretching, it enables posture maintenance with lesser force due to decreased muscle activity, it is more helpful for improvements in balance ability, and it is effective in decreasing pain.

Tai Chi and Yoga for Improving Balance on One Leg: A Neuroimaging and Biomechanics Study.

The one-leg stance is frequently used in balance training and rehabilitation programs for various balance disorders. There are some typical one-leg stance postures in Tai Chi (TC) and yoga, which are normally used for improving balance. However, the mechanism is poorly understood. Besides, the differences of one-leg stance postures between TC and yoga in training balance are still unknown. Therefore, the aim of the present study was to investigate cortical activation and rambling and trembling trajectories to elucidate the possible mechanism of improving one-leg stance balance, and compare the postural demands during one-leg stance postures between TC and yoga. Thirty-two healthy young individuals were recruited to perform two TC one-leg stance postures, i.e., right heel kick (RHK) and left lower body and stand on one leg (LSOL), two yoga postures, i.e., one-leg balance and Tree, and normal one-leg standing (OLS). Brain activation in the primary motor cortex, supplementary motor area (SMA), and dorsolateral prefrontal cortex (DLPFC) was measured using functional near-infrared spectroscopy. The center of pressure was simultaneously recorded using a force platform and decomposed into rambling and trembling components. One-way repeated-measures analysis of variance was used for the main effects. The relative concentration changes of oxygenated hemoglobin (ΔHbO) in SMA were significantly higher during RHK, LSOL, and Tree than that during OLS (p < 0.001). RHK (p < 0.001), LSOL (p = 0.003), and Tree (p = 0.006) all showed significantly larger root mean square rambling (RmRMS) than that during OLS in the medial-lateral direction. The right DLPFC activation was significantly greater during the RHK than that during the Tree (p = 0.023), OLB (p < 0.001), and OLS (p = 0.013) postures. In conclusion, the RHK, LSOL, and Tree could be used as training movements for people with impaired balance. Furthermore, the RHK in TC may provide more cognitive training in postural control than Tree and OLB in yoga. Knowledge from this study could be used and implemented in training one-leg stance balance.

Influence of an Aquatic Therapy Program on Perceived Pain, Stress, and Quality of Life in Chronic Stroke Patients: A Randomized Trial.

Pain and depressive states may have a negative impact on the quality of life of individuals with stroke. The aim of this study was to evaluate the effects of a program of Ai Chi aquatic therapy on pain, depression, and quality of life in a sample of people with stroke. Forty-five participants received physiotherapy treatment on dry land (control group), an experimental group received aquatic Ai Chi therapy, and a combined therapy group received alternating sessions of physiotherapy on dry land and aquatic Ai Chi therapy. The Visual Analog Scale (VAS) scale for pain, the resilience scale, and the SF-36 quality of life scale were used as outcome measures. Statistically significant differences were found in the experimental group and the combined intervention group for post treatment pain and resilience (p < 0.001). Concerning the SF-36, statistically significant changes (p < 0.01) were found in the experimental group and the combined therapy group for all items except general health, vitality, and social function, where no between group differences were observed (p = 0.001). In conclusion, physical exercise performed in water has positive effects on several factors that contribute towards improving the mood and quality of life of people with acquired brain injury.

The Benefits of T'ai Chi for Older Adults with Chronic Back Pain: A Qualitative Study.

Objective: To determine the perceived benefits of t'ai chi in older adults with chronic low-back pain (cLBP). Design: A qualitative analysis from a randomized controlled feasibility trial. Subjects: Eighteen participants (65+ years old) with cLBP of at least moderate intensity. Intervention: A 36-week intervention beginning with twice weekly classes for 12 weeks, weekly classes for 6 weeks, biweekly classes for 6 weeks, and monthly classes for 12 weeks. Participants were asked to practice at home on nonclass days and videos were provided to assist in that process. Outcome Measures: Participants in the focus groups were asked to provide feedback on their experiences with the study as well as the benefits of their t'ai chi practice. We used demographic and class attendance data to describe the sample. Results: Regarding the benefits of t'ai chi practice, five major themes were identified: functional benefits, pain reduction/pain relief, psychospiritual benefits, the importance of social support in learning t'ai chi, and the integration of t'ai chi into daily activities. The most common functional benefits were improvements in balance, flexibility, leg strength, and posture. Some reported pain reduction or pain relief, but others did not. Increased relaxation, mindfulness, and a sense of connectedness were subthemes that emerged from psychospiritual benefits. Social support benefits included motivation to attend class and group support while learning a new skill. Finally, improved body awareness allowed participants to integrate t'ai chi skills into their daily activities. Conclusions: This qualitative analysis demonstrates the multifaceted benefits of t'ai chi for older adults living with cLBP.

T'ai Chi for Chronic Low Back Pain in Older Adults: A Feasibility Trial.

Objectives: T'ai chi (TC) has been found effective for improving chronic low back pain (cLBP). However, such studies did not include adults over 65 years of age. This study was designed to evaluate the feasibility and acceptability of TC in this population compared with Health Education (HE) and with Usual Care (UC). Design: Feasibility randomized controlled trial. Settings/Location: Participants were recruited from Kaiser Permanente Washington and classes took place in a Kaiser facility. Patients: Adults 65 years of age and older with cLBP. Interventions: Twenty-eight participants were randomized to 12 weeks of TC followed by a 24-week tapered TC program, 12 were assigned to a 12-week HE intervention and 17 were assigned to UC only. Outcome Measures: Feasibility and acceptability were determined by recruitment, retention and 12-, 26-, and 52-week follow-up rates, instructor adherence to protocol, class attendance, TC home practice, class satisfaction, and adverse events. Results: Fifty-seven participants were enrolled in two cohorts of 28 and 29 during two 4-month recruitment periods. Questionnaire follow-up completion rates ranged between 88% and 93%. Two major class protocol deviations were noted in TC and none in HE. Sixty-two percent of TC participants versus 50% of HE participants attended at least 70% of the classes during the 12-week initial intervention period. Weekly rates of TC home practice were high among class attendees (median of 4.2 days) at 12 weeks, with fewer people practicing at 26 and 52 weeks. By 52 weeks, 70% of TC participants reported practicing the week before, with a median of 3 days per week and 15 min/session. TC participants rated the helpfulness of their classes significantly higher than did HE participants, but the groups were similarly likely to recommend the classes. Conclusion: The TC intervention is feasible in this population, while the HE group requires modifications in delivery.

The Effect of Tai Chi on Quality of Life in Centrally Obese Adults with Depression.

Objectives: The aim of this pilot study was to assess the effects of a t'ai chi program on health-related quality of life (HR-QOL) in centrally obese adults with depression. Methods: Two hundred thirteen participants were randomly allocated to either a t'ai chi intervention group (n = 106) or a usual medical care control group (n = 107). The t'ai chi group involved 3 × 1.5 h supervised and group-based training sessions per week for 24 weeks. Indicators of HR-QOL were assessed by questionnaire at baseline, 12 weeks, and 24 weeks. Results: There were significant improvements in favor of the t'ai chi group for the SF-36 subscales of physical functioning (p < 0.01), role physical (p < 0.01), and role emotional (p < 0.01) at 12 and 24 weeks. Scores for bodily pain were improved in the control group at 12 weeks (p < 0.01) and 24 weeks (p < 0.05), but not in the t'ai chi group. There was also a significant improvement in favor of the control group in general health (p < 0.05) at 12 weeks, but not at 24 weeks. A further analysis showed clinically significant changes in favor of the t'ai chi group in physical functioning (p < 0.05 or p = 0.05), role physical (p < 0.05), and role emotional (p < 0.05), and in favor of the control group in bodily pain (p < 0.05) at 12 and 24 weeks. Conclusions: The findings show that t'ai chi exercise improved indicators of HR-QOL including physical functioning, role physical, and role emotional in centrally obese adults with depression.

Does the speed of aquatic therapy exercise alter arm volume in women with breast cancer related lymphoedema? A cross-over randomized controlled trial.

OBJECTIVE: To identify whether slow aquatic exercise in the form of modified Ai Chi is more effective than conventional (faster pace) aquatic therapy at reducing arm volume in women with or at risk of breast cancer related lymphoedema. METHODS: Randomized, cross-over controlled trial with concealed allocation and blinded assessment. Eighteen women with a history of breast cancer related lymphoedema were recruited. Participants received two intervention sessions (randomized order) with one week apart. Interventions were a 50min conventional aquatic intervention or a 50min modified Ai Chi. Arm volume was measured as the difference between affected and unaffected arm; bio-impedance was measured as an index of extracellular fluid; satisfaction was measured via a 12 question form. Outcomes were measured before, immediately after and one hour after intervention. RESULTS: Comparison between interventions showed larger decreased arm volume of 140mL (95%CI 17-263) immediately after intervention in favor of the Ai Chi intervention, however it was not sustained at 1h follow-up. A post hoc analysis showed 72% of participants had a decrease in arm volume immediately after Ai Chi compared to 28% immediately after conventional aquatic therapy; with a number needed to treat of 3 (95%CI 1.4-6.6). There were no differences between interventions for bio-impedance. Satisfaction was good for both interventions. CONCLUSION: Slow pace aquatic exercise is more effective than conventional aquatic exercise immediately after intervention for arm volume. Also, undesirable increase in arm volume seems to subside after 1h, which can be beneficial if therapy does not address arm volume.

Feasibility and preliminary efficacy of Ai Chi aquatic exercise training in Hong Kong's older adults with risk of falling: Design and methodology of a randomized controlled trial.

Falls in older adults are a major global public health concern. Group exercise could mitigate fall risk but the traditional land-based group exercise may not be always suitable for older adults at risk of falling, especially for those with musculoskeletal problems. Ai Chi aquatic exercise program could provide a safe and low-impact exercise training for older adults. However, the feasibility and efficacy of the program has not been well-investigated. The objective of this study is to investigate the feasibility and efficacy of the Ai Chi aquatic exercise program, compared to the land-based exercise program for older adults with moderate to high risk of falling. Forty community-dwelling older adults aged 65 or above with moderate to high fall risk will be recruited. They will be randomly allocated in the Ai Chi Aquatic Exercise Group (intervention) or the Land-based Exercise Group (active control) receiving 16 sessions (8 weeks) of specific exercise training. Feasibility of both exercise groups will be examined by recruitment, adherence, retention, feedback, subjective exercise experiences and satisfaction. Preliminary efficacy will be determined by whether physical and psychological fall risk factors could be mitigated. Physical fall risk assessment will include tests for flexibility, muscle strength, gait and balance. Psychological fall risk will be evaluated by preliminary cognitive function, anxiety level, level of depression and fear of falling. The results could establish a solid foundation for worldwide development of a feasible, safe and effective Ai Chi aquatic exercise program for prevention of falls in older adults with risk of falling.

A 4-week community aquatic physiotherapy program with Ai Chi or Bad Ragaz Ring Method improves disability and trunk muscle endurance in adults with chronic low back pain: A pilot study.

OBJECTIVE: To investigate the efficacy of a 4-week community aquatic physiotherapy program with Ai Chi or the Bad Ragaz Ring Method (BRRM) on pain and disability in adults with chronic low back pain (CLBP). METHODS: Adults with CLBP (n= 44; mean ± SD age, 52.6 ± 5.5 y; 37 women) were assigned to either an Ai Chi (n= 23) or BRRM (n= 21) program (4 weeks, twice weekly). RESULTS: Both the Ai Chi (-1.4; 95% CI -2.6 to -0.2; p= .025) and BRRM (-2.0, 95% CI -3.1 to -0.8; p= 0.003) groups demonstrated significant pre- to post-treatment decreases in Roland-Morris Disability Questionnaire scores and improvements in prone bridge duration (Ai Chi: 11.7 s; 95% CI 1.6 to 21.8; p= 0.025; BRRM: 19.0 s; 95% CI 6.1 to 31.8; p= 0.006). The Ai Chi group revealed a significant improvement in single-leg stand test duration (2.9 s; 95% CI 0.1 to 5.7; p= 0.045) and the BRRM group reported significant decrease in pain intensity (-11.6; 95% CI -19.1 to -4.2; p= 0.004). CONCLUSIONS: A 4-week aquatic physiotherapy program with Ai Chi or BRRM resulted in significant pre- to post-treatment improvements in disability and global core muscle endurance. Ai Chi appeared to have an additional benefit of improving single-leg standing balance and BRRM an additional benefit of reducing pain.

The Effect of T'ai Chi Exercise on Lipid Profiles: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

BACKGROUND: Cardiovascular disease is a common health problem resulting from many factors, including dyslipidemia. T'ai chi is one of the interventions assigned to improve lipid profiles and other physical outcomes. However, conflicting results might be attributed to different study designs and interventional approaches. A systematic review and meta-analysis are needed to evaluate existing evidence. OBJECTIVE: The aim of this systematic review and meta-analysis is to evaluate existing randomized clinical trials (RCTs) regarding the overall effect of t'ai chi exercise on lipid profiles. METHODS: Electronic databases (MEDLINE and Cumulative Index to Nursing and Allied Health Literature) were searched. The authors included only English peer reviewed published RCTs that used a t'ai chi intervention and high-density lipoprotein cholesterol (HDL-C) as the primary outcome along with low-density lipoprotein cholesterol (LDL-C) and/or total cholesterol (TC) as secondary outcomes. RESULTS: The authors identified 37 potentially eligible studies. Only eight RCTs were eligible for their qualitative review, and seven studies were eligible for meta-analysis. The included studies were rated as having a low risk of bias. Despite the overall low risk of bias, all studies failed to blind participants to group assignment and were generally unclear about whether they were selectively reporting data. A fixed effect model (I2 = 38.16%) demonstrated a small positive effect of t'ai chi on HDL-C (Cohen d = 0.12; standard error [SE] = 0.067; p = 0.037). A random effect model demonstrated a medium effect and small effect for LDL-C (Cohen d = 0.47; SE = 0.347; p = 0.089) and TC (Cohen d = 0.34; SE = 0.225; p = 0.066), respectively. CONCLUSION: T'ai chi may potentially be beneficial on lipid profiles across different age groups and populations. Although there were conflicting results regarding the effect of t'ai chi on lipid profiles, the majority of studies had at least a small positive effect indicating a potential positive effect of t'ai chi on HDL-C, LDL-C, and/or TC. Therefore, further research is needed to confirm the small positive effect of t'ai chi on lipid profiles found in this review.

A new approach towards improved quality of life in fibromyalgia: a pilot study on the effects of an aquatic Ai Chi program.

BACKGROUND: Fibromyalgia syndrome (FMS) is a rheumatic disorder that presents with physical, psychological and social symptoms. OBJECTIVE: The aim of this study was to assess the effects of a program of water-based Ai Chi on the health-related quality of life of subjects with FMS. METHODS: An experimental pilot study was performed with a sample of 20 female subjects diagnosed with FM and recruited from two different settings. Assessments were performed using the a visual analog scale and the Short Form-36 physical and mental health summary scores. Measurements took place at baseline and upon completion of 10 treatment sessions. RESULTS: After 10 treatment sessions, significant improvements (P < 0.05) were found in practically all the variables under study, with significant differences in values such as pain perception, vitality, mental health, as well as perceived overall improvement in quality of life. CONCLUSIONS: A water-based Ai Chi program may contribute to the improvement of mental and physical health and the quality of life in women with FMS.

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

PURPOSE: In this study, we aimed to investigate effects of Ai Chi on balance, functional mobility, health-related quality of life, and motor impairment in patients with Parkinson's disease. METHOD: This study was conducted as an open-label randomized controlled trial (ISRCTN26292510) with repeated measures. Forty patients with Parkinson's disease stages 2 to 3 according to the Hoehn and Yahr Scale were randomly allocated to either an Ai Chi exercise group or a land-based exercise control group for 5 weeks. Balance was measured using the Biodex-3,1 and the Berg Balance Scale. Functional mobility was evaluated using the Timed Up and Go Test. Additionally, health-related quality of life and motor activity were assessed with the Parkinson's Disease Questionnaire-39 and the Unified Parkinson's Disease Rating Scale-III. RESULTS: Although patients in both groups showed significant improvement in all outcome variables, improvement of dynamic balance was significantly greater in the Ai Chi group (p < 0.001), Berg Balance Scale (p < 0.001), Timed Up and Go Test (p = 0.002), Parkinson's Disease Questionnaire-39 (p < 0.001), Unified Parkinson's Disease Rating Scale-III (p < 0.001). CONCLUSION: Our results suggest that an Ai Chi exercise program improves balance, mobility, motor ability, and quality of life. In addition, Ai Chi exercise was more effective as an intervention than land-based exercise in patients with mild to moderate Parkinson's disease. Implications for rehabilitation Ai Chi exercises (aquatic exercises) may help improve balance, functional mobility, health-related quality of life, and motor ability in patients with mild to moderate Parkinson's disease more efficiently than similar land-based exercises. Ai Chi exercises should be considered as a rehabilitation option for treatment of patients with mild or moderate Parkinson's disease.

Effects of a T'ai Chi-Based Health Promotion Program on Metabolic Syndrome Markers, Health Behaviors, and Quality of Life in Middle-Aged Male Office Workers: A Randomized Trial.

OBJECTIVES: To determine the effects of a t'ai chi-applied worksite health promotion program on metabolic syndrome markers, health behaviors, and quality of life in middle-aged male office workers at a high risk of metabolic syndrome. DESIGN: A prospective randomized controlled study. SETTING: Health center of a government office building in Korea. SUBJECTS: Forty-three male office workers with two or more metabolic syndrome markers. INTERVENTIONS: The office workers were randomly assigned either to an experimental group that received t'ai chi combined with health education twice weekly for 12 weeks, or to a control group that received health education only. OUTCOME MEASURES: Blood sampling for metabolic syndrome markers and structured questionnaires for health behaviors and quality of life. RESULTS: The experimental group showed significant reductions in systolic (t = -3.103, p = 0.003) and diastolic (t = -2.159, p = 0.037) blood pressures and the triglyceride level (t = -2.451, p = 0.019) compared with the control group. Those in the experimental group also performed health behaviors more frequently (t = 4.047, p < 0.001) and reported a significantly better quality of life (t = 3.193, p = 0.003) than those in the control group. CONCLUSION: The study findings show that t'ai chi was an effective adjunctive intervention in a worksite health promotion program for middle-aged office workers at a high risk of metabolic syndrome. Future studies should examine the long-term effects of t'ai chi-applied worksite health promotion programs in individuals with confirmed metabolic syndrome.

An Ai Chi-based aquatic group improves balance and reduces falls in community-dwelling adults: A pilot observational cohort study.

BACKGROUND: Falls are associated with morbidity, loss of independence, and mortality. While land-based group exercise and Tai Chi programs reduce the risk of falls, aquatic therapy may allow patients to complete balance exercises with less pain and fear of falling; however, limited data exist. OBJECTIVE: The objective of the study was to pilot the implementation of an aquatic group based on Ai Chi principles (Aquabalance) and to evaluate the safety, intervention acceptability, and intervention effect sizes. DESIGN: Pilot observational cohort study. METHODS: Forty-two outpatients underwent a single 45-minute weekly group aquatic Ai Chi-based session for eight weeks (Aquabalance). Safety was monitored using organizational reporting systems. Patient attendance, satisfaction, and self-reported falls were also recorded. Balance measures included the Timed Up and Go (TUG) test, the Four Square Step Test (FSST), and the unilateral Step Tests. RESULTS: Forty-two patients completed the program. It was feasible to deliver Aquabalance, as evidenced by the median (IQR) attendance rate of 8.0 (7.8, 8.0) out of 8. No adverse events occurred and participants reported high satisfaction levels. Improvements were noted on the TUG, 10-meter walk test, the Functional Reach Test, the FSST, and the unilateral step tests (p < 0.05). The proportion of patients defined as high falls risk reduced from 38% to 21%. The study was limited by its small sample size, single-center nature, and the absence of a control group. CONCLUSIONS: Aquabalance was safe, well-attended, and acceptable to participants. A randomized controlled assessor-blinded trial is required.

Effects of T'ai Chi on Serotonin, Nicotine Dependency, Depression, and Anger in Hospitalized Alcohol-Dependent Patients.

OBJECTIVES: The aim of this study was to investigate the effects of t'ai chi on blood serotonin levels, nicotine dependence, depression, and anger in hospitalized alcohol-dependent patients. METHOD: This study followed an experimental and nonequivalent control group in a non-synchronized design. It was performed in a hospital located in Young Ju city, Korea, from April to August 2013. Thirty-eight patients who were hospitalized with alcohol dependence were included. They were randomly divided into an experimental and a control group, with 19 patients in each group. Patients in the experimental group practiced the 24-posture yang style t'ai chi for 50 min three times per week for 8 weeks as part of the routine hospital rehabilitation program, and those in the control group followed only the routine hospital rehabilitation program. The effect of treatment was measured using blood serotonin levels and a questionnaire on nicotine dependence, depression, and anger. Both measurements were performed before and after 8 weeks of intervention. Data were analyzed using the t-test, chi-square test, and paired t-tests. RESULTS: The experimental group showed a significantly increased blood serotonin level (p = 0.001) and significantly reduced nicotine dependence, depression, and anger (p = 0.001) than the control group did after 8 weeks of treatment. CONCLUSIONS: T'ai chi was shown to be an effective nursing intervention in hospitalized alcohol-dependent patients.

Does T'ai Chi Gait Reduce External Knee Adduction Moment?

INTRODUCTION: T'ai chi chuan is a beneficial exercise of improving health and function. Biomechanical insights of t'ai chi chuan are less understood. OBJECTIVES: To study t'ai chi gait (TCG), a common form of t'ai chi chuan in order to quantify external knee adduction moment (EKAM) as a key indicator of mechanical loading of the medial compartment of the knee compared with normal walking (NW). DESIGN: A quantitative biomechanics approach to determine peak EKAM for NW and TCG. RESULTS: There were a tri-modal pattern of EKAM during TCG and a bimodal pattern of EKAM during normal walking. In addition, subsequent analysis showed a 25%-47% reduction in peak EKAM during double support phases of TCG compared with NW; the peak EKAM of TCG during single-limb support phase showed significantly higher magnitude than the other two double-support phases. CONCLUSION: These results indicate that t'ai chi chuan might be a beneficial intervention for reducing the medial mechanical load at the knee joint, particularly during the first double-support phases of TCG, but the special consideration of higher peak EKAM of single-limb support phase is needed during regular t'ai chi chuan practice.

Seated T'ai Chi in Older Taiwanese People Using Wheelchairs: A Randomized Controlled Trial Investigating Mood States and Self-Efficacy.

OBJECTIVE: There is growing interest in t'ai chi, but little research has addressed whether t'ai chi is effective in older people using wheelchairs for mobilization. The aim of this study was to compare the effects of seated t'ai chi exercise and usual standard activities on mood states and self-efficacy in older people living in a long-term care facility and using wheelchairs for mobilization. DESIGN: Randomized controlled trial (trial registration no. ACTRN12613000029796). SETTING: One long-term-care facility in Taiwan. PARTICIPANTS: Sixty participants were randomly assigned by a computer-generated random sequence to a t'ai chi group (n = 30) or a usual exercise and entertainment activities group (n = 30). INTERVENTION: Seated t'ai chi exercise for 40 minutes three times a week for 26 weeks was provided. MAIN OUTCOME MEASURES: Mood states (Profile of Mood States Short Form [POMS-SF]) and self-efficacy (Self-Efficacy for Exercise [SEE]). RESULTS: At week 26, participants in the t'ai chi group reported significantly lower mood states on the fatigue-inertia dimension of the POMS-SF (mean score ± standard deviation, 3.56 ± 3.71) than did the control group (mean score, 7.16 ± 6.36) (F [1, 58] = 7.15; p < 0.05). The t'ai chi group recorded significantly higher SEE levels (mean, 35.66 ± 36.83) than did those in the control group (mean, 15.30 ± 26.43) (F [1, 58] = 6.05; p < 0.05). CONCLUSION: The findings highlight the importance of t'ai chi for a reduction in the fatigue-inertia mood state and an increase in self-efficacy for older people using wheelchairs.

Effects of Ai-Chi on balance, functional mobility, strength and fatigue in patients with multiple sclerosis: a pilot study.

BACKGROUND: Multiple Sclerosis (MS) patients are often referred to aquatic physical therapy, but unfortunately, researches on the effects of aquatic therapy in MS patients are limited. OBJECTIVE: The purpose of this study was to investigate the effects of Ai-Chi on balance, functional mobility, strength and fatigue in ambulatory patients with MS. METHODS: Twenty-three ambulatory female patients were divided into two groups as experimental (n = 15) or control (n = 8) for an 8-week treatment program. The experimental group underwent Ai-Chi exercises in a swimming pool and the control group performed active arm and leg exercises combined with abdominal breathing exercises at home. Static standing balance was measured with duration of one-leg stance, functional mobility was evaluated with Timed-up and Go test and 6 minute walk test, upper and lower muscle strength was assessed with hand-held dynamometer and fatigue was evaluated with Fatigue Severity Scale. RESULTS: Improvements were observed in static standing balance, functional mobility, upper and lower extremity muscle strength and fatigue in the Ai-Chi group (p < 0.05), but no significant differences in any outcome measures were observed in the control group (p > 0.05) after the intervention. CONCLUSIONS: According to these findings Ai-Chi may improve balance, functional mobility, upper and lower extremity muscle strength and fatigue in patients with MS.

Os efeitos do método Ai Chi em pacientes portadoras da síndrome fibromiálgica / The effect of Ai Chi method in fybromialgic patients

O objetivo do estudo é demonstrar os efeitos do método Ai Chi como forma alternativa de abordagem hidroterapêutica em pacientes portadoras da síndrome fibromiálgica. Foram estudados dez pacientes; quatro fizeram parte do grupo experimento e cinco, do grupo controle, com uma desistência. As pacientes foram avaliadas através do Questionário de Impacto da Fibromialgia (QIF) e da Escala de Intensidade e Índice de dor nos Pontos Sensíveis. Foram realizadas duas avaliações, uma antes e outra após o tratamento. As pacientes foram submetidas a dez sessões do método Ai Chi, com duração de quarenta minutos. Houve melhora na intensidade da dor, de acordo com a escala da intensidade de dor nos pontos sensíveis, após a intervenção; já a qualidade de vida manteve-se sem alteração. Na qualidade de vida, observou-se que os grupos obtiveram resultados semelhantes; isso se deve ao fato que as pacientes não apresentaram melhora no seu estado depressivo. No índice dos pontos sensíveis, verificou-se diferença entre os grupos. A explicação para essa diferença deve-se possivelmente aos benefícios da imersão em água aquecida e aos efeitos do método Ai Chi. Não houve diferença significativa entre os grupos, o que pode ser atribuído às limitações do estudo. Desta forma, torna-se relevante a realização de novos estudos referentes à aplicação do método Ai Chi em pacientes portadoras da síndrome fibromiálgica.

The objective of this article is to show the effect of the Ai Chi method, as an alternative form of hydrotherapeutic approach in fibromyalgia syndrome patients. Ten patients were studied, four were part of the experiment group and five of the control group, with one desistance. The patients were evaluated through the Fibromyalgia Impact Questionnaire (QIF) and Scale of Intensity and Index of pain in Sensible Points. Two evaluations were performed, before and after the treatment. The patients were submitted to ten sessions of the Ai Chi method during 40 minutes. The scale of intensity of pain in sensible points presented an improvement in the intensity of pain after the intervention, while quality of life remained without alteration. Regarding the quality of life, it was observed that the groups had similar results, because of the fact that patients had not presented improvement at depressive state. It was also verified a difference in the index of the sensible points between the groups; the explanation for this difference might be because of the benefits of the immersion in warm water and the effect of the Ai Chi method. There was no significant difference between the groups, which can be attributed to its limitations. In this way, new studies referring to the application of the Ai Chi method in patients carrying fibromyalgia syndrome become relevant.
