Plantarflexion and dorsiflexion range of motion and strength in the elderly subject

1 May 1988


Ankle plantarflexion and dorsiflexion ROM and strength of older subjects was compared to ankle plantarflexion and dorsiflexion ROM and strength of younger subjects. The Cybex machine was used for all tests which included strength tests at 60 degrees/sec and 180 degrees/sec, and ROM and endurance tests at 180/sec. The results indicated no significant differences in ankle plantarflexion and dorsiflexion ROM between the older and younger subjects. This suggests that ROM deficits in healthy elderly individuals should not be treated as an effect of old age. Strength of ankle plantarflexion and dorsiflexion in the elderly subjects was significantly lower than ankle plantarflexion and dorsiflexion strength in the younger subjects. Studies indicate that muscles in the elderly are trainable and with the proper training program, they can increase their strength.
