Muscle activation during maximum voluntary contraction and m-wave related in healthy but not in injured conditions: Implications w

Highlights

Normalizing electromyography in individuals with muscle inhibition is challenging
M-wave normalization may be useful but has mostly been studied in healthy normals
We measured maximum voluntary contraction and M-wave in people with Achilles repair
Maximum voluntary contraction and M-wave were related only on the uninjured side
M-wave is preferable to normalize electromyography in populations with concern for inhibition
