Table 1.

Modified British Medical Research Council (BMRC) grading of sensorimotor recovery, and motor recovery on the quality of outcome after radial nerve repair [27]

Motor recovery
Poor
M0 No contraction
M1 Return of perceptible contraction in the proximal muscles
Fair
M2 Return of perceptible contraction in both proximal and distal muscles
M3 Return of perceptible contraction in both proximal and distal muscles of such of degree that all-important muscles are sufficiently powerful to act against resistance
Good
M4 Return of function as in stage 3 with the addition that all synergic and independent movements are possible
M5 Complete recovery
Sensory recovery
Poor
S0 No sensation
S1 Deep pain re-established
Fair
S2 Some response to touch and pin, with over-response
S3 Good response to touch and pin, without over-response
Good
S4 Location and some tactile discrimination
S5 Complete recovery
