摘要：

AimTo investigate the correlation between handgrip strength and performance of knee flexor and extensor muscles determined using an isokinetic dynamometer in community-dwelling elderly women. MethodsThis was a cross-sectional study. Sample selection for the study was made by convenience, and 221 (71.074.93 years) community-dwelling elderly women were included. Knee flexor and extensor muscle performance was measured using an isokinetic dynamometer Biodex System 3 Pro. The isokinetic variables chosen for analysis were peak torque, peak torque/bodyweight, total work/bodyweight, total work, average power, and agonist/antagonist ratio at the angular velocities of 60 degrees/s and 180 degrees/s. Assessment of handgrip strength was carried out using the Jamar dynamometer. Spearman's correlation coefficient was calculated to identify intervariable correlations. ResultsOnly knee flexor peak torque (60 degrees/s) and average power (60 degrees/s), and knee extensor peak torque (180 degrees/s) and total work (180 degrees/s) were significantly (P<0.05), yet poorly, correlated with handgrip strength (r<0.30). ConclusionThe majority of analyses did not show any correlation between variables assessed by isokinetic dynamometer and handgrip dynamometer. Caution is required when generalizing handgrip strength as a predictor of global muscle strength in community-dwelling elderly women. Geriatr Gerontol Int 2014; 14: 185-189.
