Evaluation of Sensory Loss to the Traumatized Arm

Published:December 14, 2009DOI:
      Sensory loss caused by direct trauma to a cutaneous nerve is a common complaint after penetrating trauma. Evaluation of the loss is important and often dictates a decision to refer a patient to another unit for exploration and microsurgical repair. Although the use of modalities such as two-point discrimination and threshold testing with monofilament hairs are well established for the assessment of sensation in the hand, they are not readily applicable to more proximal nerve territories. Evaluation of sensibility is critical to management and treatment of the nerve-injured patient. Although the validity and inter-observer reliability of two-point discrimination in the fingertip has been proven, there is no validated test for proximal nerve injuries (
