Abstract

A rat-tail vibration injury model was developed to test the effects of sinusoidal vibration in the 30 to 800 Hz range. An Atlas Copco riveting hammer (RRHO4P) accelerated a fan-shaped, steel tool bit that served as the vibration platform. Male Sprague-Dawley rats were divided into 4 groups impact vibration immediate, vibration 4-day recovery, immediate sham control and 4-day sham control. Tail flick response times, measured before vibration treatment, are found to be similar for the vibration and sham groups. Tail flick times for the vibration immediate rats are 34% shorter than the pie-vibration values. The sham controls are unchanged from the pre-vibration values. Exposure of the rat tail to a single period of impact shock vibration produces profound changes in the function and structure of the innervation.
