Sensory nerve action potentials in patients with peripheral nerve lesions.
8 CB: conduction block, NA: not avaible, 2nd F-W: second finger-wrist, 5thF-W: fifth finger-wrist, EDB: extansor digitorum brevis, AHB: abductor hallusis brevis, CMAP: Compound muscle action potential, SNAP: Sensory nerve action potential
A sensory conduction study of the median, ulnar, and sural nerves revealed reduced sensory nerve action potential amplitude and delayed onset latency.
The Cadwell Sierra LT electromyograph and stimulator (Cadwell Laboratories, Inc, Kennewick Washington) were used to measure the compound motor action potential (CMAP) and sensory nerve action potential (SNAP) latencies and amplitudes.
Low amplitude sensory nerve action potential and multifocal compound muscle action potential and normal or minimally decreased velocity were reported in the previous studies with RA patients (14-16).
The sensory nerve action potential and compound muscle action potential was found to be reduced more than the conduction velocity.
Neurophysiological grades were defined as (a) mild CTS: prolonged distal sensory peak latency with +- decreased sensory amplitude, (b) moderate CTS: abnormal median sensory peak latencies with prolongation of the distal motor latency, (c) severe CTS: prolonged motor and sensory distal peak latency either with a low or absent sensory nerve action potential (SNAP) or compound muscle action potential (CMAP), (d) very severe CTS: absent thenar motor or sensory response either with a present or absent lumbrical response.
The Cadwell Sierra LT electromyograph and stimulator (Cadwell Laboratories, Inc, Kennewick, WA) were used to measure the compound motor action potential (CMAP) and sensory nerve action potential (SNAP) latencies and amplitudes.
8%) (prolonged sensory response latency, slower sensory conduction velocity, non-obtained sensory nerve action potential, etc.
On the affected side, median compound muscle action potential (CMAP) amplitudes were low, median sensory conduction velocity and sensory nerve action potential (SNAP) amplitudes were normal.
