The British Medical Research Council (MRC) developed a clinical scale for grading sensory recovery after peripheral nerve injury.
Clinical Findings
Grade
no sensibility (no sensation)
S0
recovery of deep cutaneous pain sensibility
S1
some degree of superficial cutaneous pain and tactile sensibility
S2
return of superficial cutaneous pain and tactile sensibility throughout the autonomous area with disappearance of over-reaction
S3
return of superficial cutaneous pain and tactile sensibility with some recovery in 2-point discrimination
S4
complete recovery
S5
