Current perception threshold in evaluating foot pain. Two case presentations.
Two cases are reported in which patients presented with complaints of foot pain, and a clinical suspicion of radiculopathy was supported by current perception threshold testing. Chiropractic manipulation of the lumbar spine resulted in alleviation of the lower extremity symptoms. Current perception threshold testing is a valuable neurologic testing modality that is noninvasive, nonaversive, and highly reliable for evaluation of sensory nerves where neuropathy is suspected. This technology has been described for evaluation of diabetic neuropathy, uremic screening, and alcohol and chemical toxicity. Additionally, current perception threshold is useful for evaluation of other neuropathies, such as carpal tunnel syndrome and other entrapment neuropathies. The authors encourage further investigation of this modality in the diagnosis and evaluation of peripheral neuropathy and unexplained foot pain secondary to spinal nerve impingement.
