Motor Recovery and Muscle Strength following SCI

Describe the natural history of motor recovery and muscle strength following SCI.
1. Natural muscle strength recovery may occur up to two years post injury, with the recovery rate being more significant for the first six months as measured by manual muscle testing.
2. Muscle strength gains have been attributed to two different mechanisms in healthy subjects. In healthy subjects, short-term gains (2-4 weeks) might be explained by improved capacity to recruit motor units (neural adaptation) and gains observed after 4 weeks have been attributed to morphological changes within the contractile tissue inducing muscle fiber hypertrophy.
