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 |
Purpose: To grade the recovery in sensory function after a peripheral nerve injury using the British MRC scale.
Specialty: Neurology
Objective: severity, prognosis, stage
ICD-10: T14.4,
