Table 2 Modified British Medical Research Council (BMRC) grading of sensorimotor recovery, and motor recovery on the quality of outcome after brachial plexus repair [16].
From: Surgical outcomes of the brachial plexus lesions caused by gunshot wounds in adults
Motor recovery | ||
|---|---|---|
Poor | M0 | No contraction |
| Â | M1 | Return of perceptible contraction in the proximal muscles |
Fair | M2 | Return of perceptible contraction in both proximal and distal muscles |
| Â | 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 |
| Â | M5 | Complete recovery |
Sensory recovery | ||
|---|---|---|
Poor | S0 | No sensation |
| Â | S1 | Deep pain re-established |
Fair | S2 | Some response to touch and pin, with over-response |
| Â | S3 | Good response to touch and pin, without over-response |
Good | S4 | Location and some tactile discrimination |
| Â | S5 | Complete recovery |
