Methods In a randomized control study, 59 patients were randomly divided into two groups in sequence of admission. Both groups were given conventional medical treatment; the acupuncture combined with rehabilitation training group (group A, 30 cases) was treated with trunk muscles acupuncture combined with rehabilitation training, and the rehabilitation training group (group B, 29 cases) was treated with rehabilitation training alone. Both groups were treated six times per week with four weeks as a course of treatment, and a total of four courses were given. Before and after treatment, efficacy of balance function and integral of activities of daily living (ADL) of patients were evaluated. Results The score of balance function of patients in group A and in group B after treatment (38.47 ± 11.34, 32.55 ± 10.02) was higher than that in the two groups before treatment (14.56 ± 6.00, 13.51 ± 6.28), and the differences were statistically significant (both P〈0.05). After treatment, the score of balance function of patients in group A was higher than that in group B (P〈0.05). The score of ADL of patients in group A and in group B after treatment (61.33 ± 18.47, 51.72 ± 17.28) was higher than that in the two groups before treatment (22.50 ± 6.79, 24.48 ± 7.23), and the differences were statistically significant (both P〈0.05). After treatment, the score of ADL of patients in group A was higher than that in group B (P〈0.05). Conclusion The balance function and ADL of patients with post-stroke balance disorders could be improved with trunk muscles acupuncture combined with rehabilitation training, and its efficacy was superior to rehabilitation training alone.展开更多

We aimed to determine whether WMH was associated with dysfunctions of balance and gait, and other sensorimotor factors leading to falls, and the independent factors related to falls in older Chinese people. The protective effect of exercise against falls was also addressed. Methods: In a representative sample of hospital-based individuals aged 50 years and older in China, the patients' history of falls, magnetic resonance imaging data, scores on the 9-item Berg Balance Scale (BBS-9) test and timed up-and-go test (TUGT), and sensorimotor measures of computerized dynamic posturography (CDP) were analyzed. Incident falls were recorded prospectively over a 12-month period. Using regression modeling, the association between the risk of falls and baseline WMH was estimated. Results: Only individuals with severe WMH were at an increased risk of falls, and CDP was more sensitive than BBS-9 in detecting WMH-related balance and gait dysfunction. However, WMH was not an independent predictor of falls. Taller height and overweight or obese body habitus were identified as novel protective factors for falls. Female, fall history, and increased TUGT score were identified as independent risk factors for falls in older Chinese people.展开更多
