Effects of a 12-Week Tai Chi Chuan Program Versus a Balance Training Program on Postural Control and Walking Ability in Older People
ABSTRACT Lelard T, Doutrellot P-L, David P, Ahmaidi S. Effects of a 12-week Tai Chi Chuan program versus a balance training program on postural control and walking ability in older people.
To compare the respective effects of 2 balance training programs: a Tai Chi (TC) program and a balance training program on static postural control and walking ability.
Randomized controlled trial.
Older subjects (N=28) participated in the study.
The TC group (n=14; mean age +/- SD, 76.8+/-5.1y) and the balance training group (n=14; 77.0+/-4.5y) were both trained for 12 weeks.
Static postural control was assessed via measurement of center of pressure sway under eyes open (EO) and eyes closed (EC) conditions. Walking speed over a 10-meter course was also assessed.
After the 12-week training period, there were no significant differences in walking speed or postural parameters in either the EO or EC conditions for the TC and balance training groups. Performance in the EC condition was lower than in the EO condition in pretest and posttest for the balance training and TC groups. The Romberg quotient (EO/EC ratio) was significantly higher after the balance training program than the TC program (P<.05).
We cannot conclude that the balance training program has better effects than the TC program on postural control or walking ability. None of the outcome measures showed significant change posttraining in either the TC or the balance training groups. However, the differences described in the Romberg quotient after the training period between the TC and the balance training groups suggest that TC should be helpful to limit the deleterious effects of eye closure on postural balance.

ABSTRACT: Different types of exercise are indicated for the elderly to prevent functional capacity limitations due to aging and reduce the risk of falls. This study aimed to evaluate the effect of three different exercises (mini-trampoline, aquatic gymnastics and general floor gymnastics) on postural balance in elderly women. Seventy-four physically independent elderly women, mean age 69 ± 4 years, were randomly assigned to three intervention groups: 1) mini-trampoline (n= 23), 2) aquatic gymnastics (n= 28), and 3) general floor gymnastics (n= 23). Each group performed physical training, including cardiorespiratory, muscular strength and endurance, flexibility and sensory-motor exercises for 12 weeks. To determine the effects on each intervention group, five postural balance tasks were performed on a force platform (BIOMEC 400): the two-legged stand with eyes open and closed; the semi-tandem stand with eyes open and closed and the one-legged stand. Three trials were performed for each task (with 30 s of rest between them) and the mean was used to compute balance parameters such as Centre of Pressure (COP) sway movements. All modalities investigated such as the mini-trampoline, aquatic and general floor gymnastics were significantly (P <0.05) efficient in improving the postural balance of elderly women after 12 weeks of training. These results provide further evidence concerning exercise and balance for promoting health in elderly women.Archives of Gerontology and Geriatrics 08/2014; 59(3).

ABSTRACT: Purpose: The purpose of the study was to evaluate the effect of BodyBalance ® training on balance, functional task performance, fear of falling, and health-related quality of life in adults aged over 55 years. Participants and methods: A total of 28 healthy, active adults aged 66±5 years completed the randomized controlled trial. Balance, functional task performance, fear of falling, and self-reported quality of life were assessed at baseline and after 12 weeks. Participants either undertook two sessions of BodyBalance per week for 12 weeks (n=15) or continued with their normal activities (n=13). Results: Significant group-by-time interactions were found for the timed up and go (P=0.038), 30-second chair stand (P=0.037), and mediolateral center-of-pressure range in narrow stance with eyes closed (P=0.017). There were no significant effects on fear of falling or self-reported quality of life. Conclusion: Twelve weeks of BodyBalance training is effective at improving certain balance and functional based tasks in healthy older adults.Clinical Interventions in Aging 11/2014; 9.

ABSTRACT: Abstract Although numerous studies have linked t'ai chi chuan (TCC) practice with benefits for balance, reduction in the number of falls, and in the fear of falling, most of them did not address the causes of these benefits in depth. Some studies, however, sought to determine the causes from the biomechanical point of view. This article aims to thoroughly describe and critically review recent papers on foot-ground contact in TCC practice, one of the parameters involved in balance biomechanics in TCC performance. No previous review on this subject has been found. Nine electronic databases were searched for publications between 1996 and 2013. Studies were excluded if they were not published in English or were abstracts, posters, or summaries from conferences. From a total of 195 articles identified, 4 randomized controlled trials and 3 non-randomized controlled trials were eligible for the analysis. The number of studies that assessed foot-ground contact in TCC and effects on normal gait, postural control improvement, and fall prevention is still quite small. These studies were based on intervention protocols and used populations that were too heterogeneous to allow reliable comparisons. According to the studies analyzed, TCC practice clearly improved parameters associated with foot-ground contact. Nevertheless, the manner in which these benefits are transferred to daily displacement habits still remains unclear.Journal of alternative and complementary medicine (New York, N.Y.) 08/2014; DOI:10.1089/acm.2014.0035 · 1.52 Impact Factor
