Abstract
Background: Postural instability is one of health hazards for older persons, leading to falls and injuries. Exercise is considered as a particular way to improve balance and reduce risks of fall in the elderly. At present, 9-square exercise is popular among older persons in Thailand. It has been purposed to help in improving balance in the elderly. However, an evidence in this research issue was still limited.
Objectives: To evaluate the effects of 9-square exercise on balance and leg muscle strength in the elderly.
Methods: Participants were older women living in 2 communities of mueang district, Khon Kaen province. One community was randomized to an experimental group (9-square exercise group, n=7, average age 72.0 years); the other was assigned as a control group (conventional balance exercise group, n=7, average age 71.3 years). Outcome measures were performed by balance assessment test, Timed Up and Go Test and Berg Balance Scale. Leg muscle strength was assessed by the 30-second chair sit to stand test. The assessments were performed at baseline (week 0) and immediately after termination of the program (week 4). Data were analyzed by using Independent t-test.
Results: At the end of the study, the experimental group showed significantly greater leg muscle strength than the control group (P=0.03, mean difference 3.11 times, 95% CI 0.34 to 5.88 times). No significant difference between groups was found in the balance measurement.
Conclusion: The effect of 9-square exercise on balance in older women and conventional balance exercise was similar. The 9-square exercise was thus an alternative exercise regimen for improving balance in the elderly.
