A Pilot Study of a 12-Week Leg Exercise and a 6- and 12-Month Follow-Up in Community-Dwelling Diabetic Elders: Effect on Dynamic Standing Balance.

OBJECTIVE: To determine the effects of 12-week leg exercise and follow-up on fasting blood glucose (FBG), blood pressure, static and dynamic standing balance time, leg muscle strength, and leg exercise behaviors in type 2 diabetic elderly.

MATERIAL AND METHOD: Fourfemales, completing 12-week leg exercise group and 6- and 12-monthfollow-up were examined for FBG blood pressure, standing on firm and foam surfaces, single leg stance, Five-Times-Sit-to-Stand Test (FTSST), alternated stepping, and leg muscle strength at before leg exercise, week 12 of exercise, and months 6 and 12 follow-up after exercise. Friedman's ANOVA was used to compare these variables among 4 periods. Exercise behaviors were asked at months 6 and 12follow-up.

RESULTS: Significant decreased time was observed in FTSST between before and at week 12, and alternated stepping between before and at month 6. For one year follow-up, two participants performed leg exercise regularly. According to patients' interviews, they continued leg exercise because ofreduced leg pain and stiffness, compliance to physiotherapist's suggestions, and exercise addiction.

CONCLUSION: Leg exercise enhanced FTSST and alternated stepping produced good qualityfeeling in leg in diabetic elderly. Physiotherapists may be a keyfor continuing leg exercise in community-dwelling diabetic elderly.
