Toward a Virtual Gait Trainer: gait regularity assessment in transfemoral amputees by on-body accelerometers and gyroscopes

Step and stride regularity were assessed in three transfemoral amputees and two control subjects by autocorrelation analysis of wearable inertial sensor signals. Autocorrelation parameters from acceleration were markedly lower in amputees than in control subjects during a 40 m rectilinear path (P≪0....

Abstract Step and stride regularity were assessed in three transfemoral amputees and two control subjects by autocorrelation analysis of wearable inertial sensor signals. Autocorrelation parameters from acceleration were markedly lower in amputees than in control subjects during a 40 m rectilinear path (P≪0.0015). That may allow the development of a Virtual Gait Trainer based on biofeedback.
