Abstract :
Surface-mounted accelerometers (SMA) secured tightly to body segments with an elastic strap, are commonly used to
quantify the impact response of bone. However, the effect that this type of fixation has on segment soft tissue motion
relative to bone has yet to be determined. Heel impacts were collected from 20 participants using a human pendulum
apparatus, with (strap) and without (no strap) a SMA attached to the proximal tibia. Leg soft tissue motion was
quantified using digital image analysis software which monitored positions of skin markers from a series of high speed
photographs. The strap was found to alter the natural physiological motion of the soft tissue, with significant
displacement, velocity and sex differences occurring within the most proximal regions. Future research should evaluate
alternative methods for quantifying bone and soft tissue response to impact concurrently, to advance our understanding of
impact-related injury mechanisms.
