The machines used were a Cadwell Sierra and a Neuromax Excel electrodiagnostic machines. Sensitivity, low-frequency filter, high-frequency filter, sweep speed, duration of pulse, and rate of pulse were not specified.
This study was performed in the supine position.
The authors used standard techniques but, for both median–sensory and ulnar–motor conduction techniques, they did not specify the methods chosen [
1]. For median–sensory, they did not specify which finger was tested and if the orthodromic or antidromic method was performed. For the ulnar–motor, they did not specify from which muscle motor responses were recorded, after stimulation at the wrist (abductor digiti minimi, ADM, muscle or first dorsal interosseous, FDI, muscle). For the median–sensory, following the antidromic method, we recorded signals using surface electrodes placed to digit III (Fig.
1). For the median nerve (R1), the active recording electrode (A) was placed around the...
