Is Tai Chi Chuan effective in improving lower limb response time to prevent backward falls in the elderly

Abstract: To evaluate the training effect of Tai Chi Chuan (TCC) in postural control and backward fall prevention in the elderly, balance assessment and visually guided lower limb response time were analyzed in a case-control study conducted in a community setting. Thirty-one elderly subjects (mean age: 68.2 ± 6.8 years) participated in the TCC group, 30 community-dwelling elderly subjects with matched age and body composition served as the elderly control group, with 13 young adults (mean age: 27.5 ± 3.8 years) serving as young controls. The TCC group had practiced TCC regularly five times per week, for over 30 min per day for at least 4 years. Lower limb response time were measured using a computerized dance machine that we developed, which contains two blocks during testing: single and dual feet. The motor planning of the latter is more complex than the former. Postural control was assessed by computerized posturography (Smart Balance Master). Compared to the elderly controls, the TCC group demonstrated significantly better balance performance in sway-referenced support, which is more challenging. Moreover, the TCC group had better dual feet response than the elderly controls in the forward–backward, forward–right and forward–left directions. Practicing TCC may improve motor responses and postural control in the elderly, particularly in more challenging situations. Subjects showed better postural responses to unexpected perturbation in the forward–backward and forward–sideways direction than sideways or backward–sideways directions, which may have clinical relevance.

Acceptance of different design exergames in elders.

Abstract: For promoting the successful aging of elderly residents of Chang Gung Silver Village in Taiwan, five interactive exergames were developed to promote the well-being of the elderly The exergames included both physical games and cognitive games, and were implemented using various computer-based technologies in the Chang Gung Silver Village The exergames were trialed by 39 elderly residents (15 male, 24 female; mean age 795 ± 175 years) of Chang Gung Silver Village Following the trials, the participants were requested to complete a Technology Acceptance Model 2 (TAM2) questionnaire The results showed that the perceived playfulness and perceived usefulness of the exergames were significantly related to the users' usage behavior and intention to use for both the physical games and the cognitive games However, a relationship between the output quality of the game and the usage behavior was apparent only in the case of the cognitive exergames Finally, the impact of social influence on the intention to use and the usage behavior was more pronounced for the physical exergames Overall, the results revealed that the acceptance of exergames by the elderly depends not so much on the awareness of fun in using the game, but the perceived usefulness of the related physical and cognitive abilities

Tai Chi and Fall Reductions in Older Adults: A Randomized Controlled Trial

Abstract: Background. The authors’ objective was to evaluate the efficacy of a 6-month Tai Chi intervention for decreasing the number of falls and the risk for falling in older persons. Methods. This randomized controlled trial involved a sample of 256 physically inactive, community-dwelling adults aged 70 to 92 (mean age, 77.48 years; standard deviation, 4.95 years) who were recruited through a patient database in Portland, Oregon. Participants were randomized to participate in a three-times-per-week Tai Chi group or to a stretching control group for 6 months. The primary outcome measure was the number of falls; the secondary outcome measures included functional balance (Berg Balance Scale, Dynamic Gait Index, Functional Reach, and single-leg standing), physical performance (50-foot speed walk, UpG p ¼ .007), lower proportions of fallers (28% vs 46%; p ¼ .01), and fewer injurious falls (7% vs 18%; p ¼ .03) were observed in the Tai Chi group compared with the stretching control group. After adjusting for baseline covariates, the risk for multiple falls in the Tai Chi group was 55% lower than that of the stretching control group (risk ratio, .45; 95% confidence interval, 0.30 to 0.70). Compared with the stretching control participants, the Tai Chi participants showed significant improvements ( p , .001) in all measures of functional balance, physical performance, and reduced fear of falling. Intervention gains in these measures were maintained at a 6-month postintervention follow-up in the Tai Chi group. Conclusions. A three-times-per-week, 6-month Tai Chi program is effective in decreasing the number of falls, the risk for falling, and the fear of falling, and it improves functional balance and physical performance in physically inactive persons aged 70 years or older.

Physical activity and older adults: a review of health benefits and the effectiveness of interventions

Abstract: The purpose of this multidisciplinary review paper is to critically review evidence from descriptive, efficacy and effectiveness studies concerned with physical activity and older people. Both levels of fitness (aerobic power, strength, flexibility and functional capability) and measures of physical activity involvement decline with age, and the extent to which this is due to a biological ageing processes or disuse (physical inactivity) is critically examined. The review will consider the evidence for a causal relationship between sedentary behaviour/physical activity programmes and cardiovascular, musculoskeletal and psycho-social health, independent living and health-related quality of life into old age. The review also considers the effectiveness of different physical activity interventions for older people and issues relating to cost-effectiveness. The implications for future policy in terms of research, health care services, and education and training are briefly discussed.

Kinesio taping in treatment and prevention of sports injuries: a meta-analysis of the evidence for its effectiveness.

Abstract: Kinesio tape (KT) is an elastic therapeutic tape used for treating sports injuries and a variety of other disorders. Chiropractor, Dr Kenso Kase, developed KT taping techniques in the 1970s. It is claimed that KT supports injuredmuscles and joints and helps relieve pain by lifting the skin and allowing improved blood and lymph flow. The profile of KT rose after the tape was donated to 58 countries for use during the 2008 Olympic Games, and was seen on high-profile athletes. Practitioners are asking whether they should use KT over other elastic adhesive tapes. The aim of this review was to evaluate, using meta-analysis, the effectiveness ofKT in the treatment and prevention of sports injuries. Electronic databases including SPORTDiscus®, Scopus,MEDLINE, ScienceDirect and sports medicine websites were searched using keywords ‘kinesio taping/tape’. From 97 articles, ten met the inclusion criteria (article reported data for effect of KT on a musculoskeletal outcome and had a control group) and were retained for meta-analyses.Magnitude-based inferences were used to assess clinical worth of positive outcomes reported in studies. Only two studies investigated sports-related injuries (shoulder impingement), and just one of these involved injured athletes. Studies attending to musculoskeletal outcomes in healthy participants were included on the basis that these outcomes may have implications for the prevention of sporting injuries. The efficacy of KT in pain relief was trivial given there were no clinically important results. There were inconsistent range-of-motion outcome results, with at least small beneficial results seen in two studies, but trivial results in two other studies across numerous joint measurements. There was a likely beneficial effect for proprioception regarding grip force sense error, but no positive outcome for ankle proprioception. Seven outcomes relating to strength were beneficial, although there were numerous trivial findings for quadriceps and hamstrings peak torque, and grip strength measures. KT had some substantial effects on muscle activity, but it was unclear whether these changes were beneficial or harmful. In conclusion, there was little quality evidence to support the use ofKT over other types of elastic taping in themanagement or prevention of sports injuries. KT may have a small beneficial role in improving strength, range of motion in certain injured cohorts and force sense error compared with other tapes, but further studies are needed to confirm these findings. The amount of case study and anecdotal support for KT warrants well designed experimental research, particularly pertaining to sporting injuries, so that practitioners can be confident that KT is beneficial for their athletes.
