A study of force and cross-sectional area of adductor pollicis muscle in female hip fracture patients

A study was conducted to examine the extent of muscle weaknesses experienced by older female hip fracture patients, to determine if the weakness is caused by a decline of the force produced by muscle or a decline in muscle bulk, and to investigate the process of decline. The results revealed that isometric muscle maximum voluntary force (MVF) was lowest among hip fracture group. Only part of the weaknesses could be explained by cross-sectional area.
