Table 1 Criteria for diagnosing superficial radial neuropathy [2, 4, 9,10,11, 13, 20]
From: Superficial radial neuropathy: an unobserved etiology of chronic dorsoradial wrist pain
Diagnosis of superficial radial neuropathy | Items |
|---|---|
Clinical diagnosis | - The presence of burning pain, paresthesia or numbness in the territory of the SRN. - The presence of objective sensory loss in the form of hypoesthesia or anesthesia in the territory of the SRN. - With or without the presence of positive Tinel’s sign on the lower lateral aspect of the forearm. - False-positive Finkelstein's test and/or false-positive Eichoff’s test were considered associating features provided that there is no de Quervain’s disease. |
Confirmation by the results of the sensory conduction study of the SRN. | The electrophysiological abnormalities in the SRN SNAP included the following: - Absence SNAP response. - Delayed PL (regarding the calculated cut-off value obtained from the control group). - Slowed CV (regarding the calculated cut-off value obtained from the control group). - Reduced SNAP amplitude (regarding the calculated cut-off value obtained from the control group). - When the results of the SRN sensory conduction study were within the reference cut-off value, side-to-side SNAP amplitude ratio of less than 50% was considered abnormal. |
