[A quantitative evaluation of sensory dysfunction in the cervical myelopathy by threshold test and dermatomal somatosensory evoked potentials].
A quantitative evaluation of sensory disturbance of the fingers was attempted in 68 cervical myelopathy using Biothesiometer, Semmes-Weinstein aesthesiometer (SW), pain 1 g, light touch, static-and moving-2 PD, tuning fork, and dermatomal somatosensory evoked potentials (DSSEPs). DSSEPs was the most sensitive among these tests, and Biothesiometer and SW reflected an immediate change of the sensory function. It is important to understand the characteristics of each test and to choose informative tests for clinical use. We classified the grades of sensory disturbance in patients with cervical myelopathy into 3 categories in combination with the findings of DSSEPs and the value of Biothesiometer and SW.
