Event Detection for Gluteal or Hamstring Stimulation During Walking in Neurological Patients

Event Detection for Gluteal or Hamstring Stimulation During Walking in Neurological Patients
Event Detection for Gluteal or Hamstring Stimulation During Walking in Neurological Patients
An algorithm to detect when the tibia is vertical is presented. Its intended use is to trigger a functional electrical stimulation (FES) device for either the rotation or extension of the hip (gluteal stimulation) or flexion of the knee (hamstring stimulation) in neurological patients. The algorithm comprises a correlation coefficient calculation and a set of threshold rules. Data from a healthy subject has been used as a sample window for the correlation coefficient calculation for all the neurological patients. The sample window chosen detects correctly the events in five out of seven patients and the results have showed no missing events during walking when compared to a footswitch.

Abstract

An algorithm to detect when the tibia is vertical is presented. Its intended use is to trigger a functional electrical stimulation (FES) device for either the rotation or extension of the hip (gluteal stimulation) or flexion of the knee (hamstring stimulation) in neurological patients. The algorithm comprises a correlation coefficient calculation and a set of threshold rules. Data from a healthy subject has been used as a sample window for the correlation coefficient calculation for all the neurological patients. The sample window chosen detects correctly the events in five out of seven patients and the results have showed no missing events during walking when compared to a footswitch.
