1. Figure 3. Comparison of median manual muscle test scores in the upper and lower limbs
Comparison of median manual muscle test scores in the upper and lower limbs Data were available for 189 study participants. The 5-point Medical Research Council power grade was converted to an 11-point scale (0, 1, 2, 3−, 3, 3+, 4−, 4, 4+, 5−, and 5). Observed Manual Muscle Testing scores ranged from 0 or 1 to 10 for each movement assessed, with the exception of wrist extension for which the lowest observed score was 2. Overall, the most severely affected muscle groups were hip adduction, extension, knee flexion and extension, and ankle plantar flexion, dorsiflexion, and eversion. The least severely affected muscle groups were wrist flexion and extension. Red indicates the upper limb muscles and blue indicates the lower limb muscles. COS = Clinical Outcome Study.
