Transcutaneous nerve stimulation is an alternative method that has previously been used to measure the current perception threshold (CPT) in individuals with neuropathic conditions, and various devices to measure CPT are commercially available. Nevertheless, the device must provide reproducible results to be used as an objective tool for assessing nerve blocks. Methods: We recruited ten healthy volunteers to examine CPT reproducibility using the Neurometer® and the Stimpod NMS450 peripheral nerve stimulator. Each subject's CPT was determined for the median (second digit) and ulnar (fifth digit) nerve sensory distributions on both hands - with the Neurometer at 5Hz, 250Hz, and 2000Hz and with the Stimpod at pulse widths of 0.1 msec, 0.3 msec, 0.5 msec, and 1.0 msec, both at 5Hz and 2Hz. Intraclass correlation coefficients (ICC) were also calculated to assess reproducibility; acceptable ICCs were defined as≥0.4. Results: The ICC values for the Stimpod ranged from 0.425-0.79, depending on pulse width, digit, and stimulation; ICCs for the Neurometer were 0.615 and 0.735 at 250 and 2,000Hz, respectively. These values were considered acceptable; however, the Neurometer performed less efficiently at 5Hz (ICCs for the second and fifth digits were 0.292 and 0.318, respectively). Conclusion: Overall, the Stimpod device displayed good to excellent reproducibility in measuring CPT in healthy volunteers. The Neurometer displayed poor reproducibility at low frequency (5Hz). These results suggest that peripheral nerve stimulators may be potential devices for measuring CPT to assess nerve blocks.
