Electrodiagnostic evaluation may suggest the absence of posttraumatic nerve compression
in the presence of patient symptoms. Computer-assisted neurosensory testing
documents peripheral nerve
sensory impairment. In the setting of trauma, where there are often legal implications, documentation of peripheral nerve
compression is important. This is highlighted in the diabetic, who may have neuropathy.
A prospective study tracked trauma-related peripheral nerve
problems in patients with “normal” electrodiagnostic studies, and for whom surgical care or legal outcome was determined by documentation of abnormalities by testing with the Pressure-Specified Sensory Device. Eight patients were identified, four of whom had diabetes.
In all eight patients, neurosensory testing
documented peripheral nerve
problems, which was critical in obtaining approval from workers’ compensation insurance carrier for decompression of the nerve and facilitating legal settlement.
Conclusion Neurosensory testing
with the Pressure-Specified Sensory Device identifies peripheral nerve
compression related to trauma, facilitating management of the patient, even in the presence of diabetic neuropathy.
