This study aimed to investigate the effects of Otago exercise combined with action observation (AO) training on the balance, and gait in the old people to prevent falls in the community. A total of 30 old women participated and randomly assigned into three groups: AO plus Otago (n= 10), Otago (n= 10), or control (n= 10). The AO plus Otago and Otago groups performed 50 min of strength training and balance exercises from the Otago Exercise Program 3 times a week for 12 weeks. The AO plus Otago group received an additional 20 min of training 3 times a week. We used the electronic muscle dynamometer to changes in strength, Timed Up and Go (TUG) test to evaluate dynamic balance, and the short version of the Falls Efficacy Scale-International was used to evaluate the fear of falls, and GAITRite was used to evaluate changes in the spatiotemporal parameters of walking. The muscle strength significantly increased in the AO plus Otago and Otago groups compared to the strength before training. The TUG test showed a significant improvement in the dynamic balance in both intervention groups. A significant increase was observed in the walking speed, cadence, step length, and stride length in both intervention groups. We also noted a significant change in the efficacy measures for falls. It is expected that Otago exercise combined with AO training will be used as an intervention method in hospital treatment programs and the old people facilities for preventing falls in the old people.
The objective of this study was to investigate the differences in the quality of life between two groups of patients who received or did not receive total knee replacement (TKR) surgery after being diagnosed with knee osteoarthritis (OA), and to investigate changes in the quality of life for persons who had TKR surgery. Design: Cross-sectional study. Methods: The subjects were randomized into a surgery group (n=70) and a non-surgery group (n=65). Subjects were selected from individuals diagnosed with knee OA from Himchan Hospital in Seoul, South Korea. Their sex, age, weight, height, body mass index, unilateral or bilateral, and quality of life were evaluated. Changes in the quality of life was measured using the Short Form-36 Health Survey (SF-36). Seventy out of 135 patients had TKR surgery, and their quality of life was evaluated at 6 months and 12 months after the surgery. Results: SF-36 scores were significantly improved at 6 months and 12 months after the surgery compared to the scores before the surgery (p<0.05). Also, the comparison between 6 and 12 months after surgery showed that the Vitality and Social Function scores in the SF-36 were significantly increased (p<0.05). Conclusions: The findings of this study showed that TKR surgery has a positive effect on the quality of life for persons with knee OA as a therapeutic intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
