Abstract

biomechanics

lower limb amputation

transfemoral amputation

forward fall

impact

Falling represents a health risk for lower limb amputees fitted with an osseointegrated fixation mainly because of the potential damage to the fixation. The purpose of this study was to characterize a real forward fall that occurred inadvertently to a transfemoral amputee fitted with an osseointegrated fixation while attending a gait measurement session to assess the load applied on the residuum. The objective was to analyze the load applied on the fixation with an emphasis on the sequence of events, the pattern and the magnitude of the forces and moments. The load was measured directly at 200Hz using a six-channel transducer. Complementary video footage was also studied. The fall was divided into four phases: Loading (240ms), descent (620ms), impact (365ms) and recovery (2495ms). The main impact forces and moments occurred 870ms and 915ms after the heel contact, and corresponded to 133 BW and 17 BWm, or 1.2 and 11.2 times the maximum forces and moments applied during the previous steps of the participant, respectively. This study provided key information to engineers and clinicians facing the challenge to design equipment, and rehabilitation and exercise programs to restore safely the locomotion of lower limb amputees. © 2010 ISPO.
