Motor and sensory conduction along the posterior interosseous nerve.
The posterior interosseous nerve (PIN) is the main distal branch of the radial nerve. It innervates most of the extensor muscles of the forearm and contains deep sensory fibres directed to the ligaments and joints of the wrist. The presence of deep sensory fibres allow measurement of sensory conduction (SCV) other than motor nerve conduction velocity (MCV) along this nerve. Normal values of motor and sensory conduction along the terminal branches of the radial nerve distal to the elbow are reported. The results accord well with data previously reported.
