Characterization of the performance of external hip protector materials

Abstract

An experimental method involving the use of a resiliometer was used to obtain the energy-return ability (ERA) and the deceleration (d)-versus-time (t) history for a specimen when subjected to an impact load. Specimens from five materials that are considered candidates for the padding of an external hip protector were evaluated. Through the use of the ERA, d and t results, it was found that the best material is a polyolefin copolymer containing 18% ethylene vinyl acetate. The clinical significance of the results is discussed.
