Tibial shock measured with bone and skin mounted transducers

The purpose of this study was to assess the value of superficial transducer mounting to measure tibial shock during locomotion. Surface (SMT) and bone mounted transducers (BMT) simultaneously recorded axial tibial acceleration in five subjects who ran at 4.5 m s super(-1). SMT produced inconsistent...

Description
Summary:The purpose of this study was to assess the value of superficial transducer mounting to measure tibial shock during locomotion. Surface (SMT) and bone mounted transducers (BMT) simultaneously recorded axial tibial acceleration in five subjects who ran at 4.5 m s super(-1). SMT produced inconsistent recording across the subjects both in the time and frequency domains. In two subjects, SMT signals provided close approximation of BMT signals, some distortion occurred in one subject while severe distortions were observed in the other two subjects. The present results established that SMT could not be used directly to quantify the shock transmitted through the tibia during running. However, frequency transformation of SMT recordings produced encouraging results; the transformed SMT signals mimicked the signals recorded with the bone mounted transducer.
