A new computed-assisted technique for experimental sciatic nerve function analysis.

BACKGROUND: Peripheral nerve injury is a well-known experimental tool to evaluate the effect of various neurotrophic substances. Besides histological and electrophysiological techniques, nerve functional status has been assessed by means of the sciatic function index (SFI) and the static sciatic index (SSI). However, these techniques are still based on a complex and old-fashioned apparatus requiring a relatively long time of execution. This study aimed to assess a novel, rapid, computerized method for assessment of SSI in a rat model of sciatic nerve injury. MATERIAL/METHODS: Fourteen rats were used in this study. The left sciatic nerve was exposed and compressed for 2 minutes with an aneur…
