 Multiple sclerosis, MS, is a chronic neurological condition characterized by damage to the central nervous system. People with MS often experience changes in their gait due to weakness or spasticity in the legs and feet. This can lead to difficulty walking and increased risk of falls. In this study, researchers examined the differences in muscle activation between people with MS and healthy individuals while they walked. They found that people with MS had higher levels of muscle coactivation in certain muscles than those without MS. These findings suggest that muscle coactivation could be used as a tool to detect early signs of gait abnormalities in people with MS.
