Differences in Skeletal Muscle Fiber Characteristics between Affected and Nonaffected Limbs in Individuals with Stroke: A Scoping Review

CONCLUSIONS: Of the limited available evidence, stroke appears to result in a shift to a higher proportion of type II muscle fibers in the paretic muscles. There are mixed results for effects on muscle fiber CSA, but there is some evidence of specific atrophy of type II muscle fibers.IMPACT: Changes in paretic skeletal muscle fibers of individuals with stroke may explain, in part, the substantial losses in strength and power in this population. Interventions to restore type II muscle fiber size may benefit people with stroke.PMID:37478464 | DOI:10.1093/ptj/pzad095
