Elderly women use elastic bands for stroke rehab

Changes in muscle drive as a function of age

Measuring how well people can drive their muscle to produce maximum forces tells us a lot about the voluntary control of movement. We know that muscle strength decreases as people get older, particularly after the age of 70. Despite the loss of strength, the ability to drive muscles in maximum efforts does not deteriorate with age.

This study investigated why this might be so. It also provides normative values in healthy older people that can be used when deciding rehabilitation goals after stroke.
