Effect Of Tilt Sensor Versus Heel Loading On Neuroprosthesis Stimulation Reliability And Timing For Individuals Post-Stroke During Level And Non- Level Treadmill Walking, M. Barbara Silver-Thorn

Biomedical Engineering Faculty Research and Publications

Study background: Non-level walking may adversely affect stimulation of neuroprostheses as initial programming is performed during level walking. The objectives of this study were to assess stimulation reliability of tilt and heel sensor-based neuroprosthesis stimulation during level and non-level walking, examine stimulation initiation and termination timing during level and non-level walking, and determine whether heel or tilt sensor-based stimulation control is more robust for non-level ambulation. Methods: Eight post-stroke individuals with drop foot who were able to actively ambulate within the community were selected for participation. Each subject acclimated to the neuroprosthesis and walked on a treadmill randomly positioned in …
