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 can improve factors associated with cardiovascular disease (CVD) risk in women, according to investigators based in the USA. In a randomised trial, 63 women aged 35 to 50 years, who were at increased risk for CVD, were assigned either to eight weekly group tai chi classes, or to a waitlist control. Tai chi was shown to decrease fatigue, and increase mindfulness and self-compassion. In addition, it was observed that tai chi may help down-regulate pro-inflammatory cytokines associated with underlying CVD risk (including interferon gamma, granulocyte colony stimulating factor, tumor necrosis factor interleukin 8 and interleukin 4).

Tai chi may be an effective non-pharmaceutical means of improving anxiety and poor sleep quality in young adults, according to a pilot study from America. Seventy-five adults aged 18-40 were randomised to one of three interventions: 10 weeks of tai chi classes (twice per week), 10 weeks of tai chi with a DVD or a control group who received a handout on anxiety management. Eighty-five per cent of participants were retained during the intervention and 70 per cent completed the two month follow-up assessments. To increase statistical power, the two tai chi groups were combined in the analyses of anxiety and sleep quality measures. No significant changes in anxiety were found in the control group, whereas levels of anxiety decreased significantly over time in the two tai chi groups. Sleep quality scores improved across time for all three groups, but tai chi participants who adhered to their practice reported the greatest improvement.

A group of American authors has created an evidence map of the effect of tai chi on various health outcomes, based on a systematic review of 107 systematic reviews. The map identified a number of areas with evidence of a potentially positive treatment effect on patient outcomes, indicated by statistically significant pooled treatment effects in systematic reviews, and based on a substantial number of research studies. These included hypertension, fall prevention, cognitive performance, osteoarthritis, depression, chronic obstructive pulmonary disease, pain, balance and muscle strength.

Tai chi has additional psychological benefits for patients with heart failure (HF) compared with a heart health education programme. American investigators randomised 100 patients with chronic systolic HF to a 12-week group tai chi program or an education control. At 12 weeks, semi-structured interviews were conducted on a random subset of participants. Positive themes emerged from both groups, however those in the tai chi group reported not only self-efficacy and social support, but overall empowerment, with additional gains such as internal locus of control, self-awareness and stress management.

Tai chi should be considered as a viable therapy for chronic pain conditions, according to an international team of authors. Data from 18 randomised controlled trials (1260 individuals) were included in their systematic review. The aggregated results indicated that practising tai chi led to immediate relief of chronic pain from osteoarthritis, low back pain and osteoporosis. Their results also indicated that a minimum duration of tai chi practice for chronic pain relief should be six weeks, with longer duration achieving better gains.
