The transmissibility response of the rat during whole body vibration along its long-axis

Vibration exposure has been suggested as a painful injury mechanism, but the relationship between mechanical loading and pain is unknown. The rat provides a useful model system for such pain studies, but the vibration response of the rat has not been studied. Moreover, in vivo systems preclude the use of implantable transducers needed to measure accelerations. This study used image-based and accelerometer-based methods to determine the transmissibility response of the rat for whole body vibration. Resonance was found at 8 Hz, with no difference in the responses using either image or accelerometer analyses.
