Tai chi can significantly improve cognitive function and fall risk in older adults with mild cognitive impairment (MCI). Sixty-six adults aged 60 and older with amnestic mild cognitive impairment (a-MCI) were divided into a tai chi group and a control group by Thai investigators. Participants in the tai chi group attended three tai chi classes per week for three weeks, and then practiced at home with a video, three times per week for 12 weeks. Participants in the control group received educational material related to cognitive impairment and fall prevention. At the end of the trial, performance on cognitive tests was significantly better for the tai chi group than the control group. The tai chi group also had significantly better t fall risk scores, along with significant improvements in the specific components of knee extension strength, reaction time, postural sway and lower limb proprioception.

Tai chi may help slow down age-related decline in muscle strength, according to Chinese investigators. A cross-sectional study was conducted in 205 long-term tai chi practitioners aged 60-89 and 205 age-matched controls. The strength of iliopsoas, quadriceps femoris, tibialis anterior and hamstrings in the tai chi group was higher than in the non-tai chi group. Muscle strength in the tai chi group was not found to not differ significantly between three age sub-groups (60-69, 70-79 and 80-89 years), suggesting that it can prevent the normal progressive decline in muscle strength associated with ageing. Muscle strength was correlated positively with number of years of tai chi practice.

Tai chi qigong (TCQ) may be useful for improving sleep quality in older adults with cognitive impairment. Hong Kong clinicians randomised 52 older adults with cognitive impairment who complained of sleep disturbance to either a TCQ group or a control group. The intervention group received TCQ training consisting of two 60-minute sessions each week for two months. Compared with the control group, the TCQ participants experienced improvements in global sleep quality, in particular in sleep duration (increased by 48 minutes) and habitual sleep efficiency (increased by 9.1 per cent). TCQ participants also reported better mental health-related quality of life than the control group.

Tai chi may reduce the incidence of falls more than conventional lower extremity training (LET) in the elderly, and its effects can last for at least one year. Taiwanese researchers assigned 456 older adults with a history of falling to a tai chi group (one weekly hour-long class) or a LET class (stretching, muscle strengthening and balance training) for a six-month period. The tai chi group was significantly less likely than the LET group to experience any falls during the six-month intervention and the effects remained significant after 12 months of follow-up. Participants who independently practised tai chi or LET seven times per week or more were significantly less likely to experience injurious falls than their counterparts during the intervention and follow up. Cognitive function also improved to a greater extent in the tai chi group than in the LET group over the 18-month study period.

Chinese and American investigators have found evidence that tai chi can help older women improve their cognition and postural control, specifically while dual tasking. Thirty-one older women were randomised to tai chi (three sessions per week) or a control group (general interest classes) for 16 weeks. Balance was tested in single leg stance after stepping down from a step, with and without a concurrent auditory response task. Tai chi subjects made fewer errors in the auditory test under dual-task conditions after tai chi training. They also showed significant improvements in their balance after training, in both single- and dual-task conditions. Subjects in the control group did not show any significant improvement in the dual-task condition after the intervention.

Brazilian clinicians report that acupuncture is effective for improving sleep quality and psychological distress in elderly patients with sleep problems. Forty-eight community-dwelling elderly patients were randomised to ten sessions of either verum or placebo acupuncture. Acupuncture was found to be highly effective for improving subjective scores of sleep quality depression and stress. However, immune and neuropeptide markers commonly associated with stress, sleep impairment and immunosenescence (the deterioration of the immune system due to ageing) did not show any changes in levels following the intervention.

Participating in tai chi (TC) leads to significant improvements in physical and mental health among older adults with arthritis, according to a Canadian cohort study. A 16-week intervention was conducted among 102 older adults from low-income neighbourhoods with self-reported arthritis. Participants were encouraged to attend two moderate-intensity TC sessions per week for a total of 120 minutes. Functional fitness assessment results indicated that grip strength, 30-second arm curl, timed up-and-go and 30-second chair stand improved significantly from baseline to 16 weeks. Physical functioning, general health, vitality, and mental health also improved significantly over the intervention period. These improvements in physical health and physical function scores were judged to be clinically meaningful.

Tai Chi cart enhance cognitive function in older adults, particularly in the realm of executive functioning and in individuals without significant impairment, concludes a systematic review from the USA. Twenty eligible studies with a total of 2553 participants met the authors’ inclusion criteria. The overall quality of RCTs was modest, with three of 11 trials categorised as being at a high risk of bias. Meta-analyses of outcomes related to executive function in RCTs of cognitively healthy adults indicated a large effect size when tai chi participants were compared with non-intervention controls, and a moderate effect size when compared with exercise controls. Meta-analyses of outcomes related to cognitive function in RCTs of cognitively impaired adults showed smaller – but statistically significant – effects when tai chi was compared with non-intervention controls and other active interventions. Findings from non-randomised studies added further evidence that tai chi may positively affect cognitive function.

Tai chi provides greater fall-prevention benefits than conventional physical therapy exercises for frail seniors, according to a Canadian study. A total of 152 frail older adults were randomised to receive a 15-week intervention, consisting of either supervised tai chi exercises, or conventional physical therapy. Both interventions demonstrated a protective effect on falls, but the effect of tai chi was significantly greater compared with physical therapy.
