4.3. TPADThe Tethered Pelvic Assist Device (TPAD) is a research device that applies forces via cables attached to a pelvic belt worn by a patient during treadmill training. Using force plate and motion capture data, the device ascertains the appropriate level of force for a patient and delivers forces along an adjustable vector during prescribed phase(s) of gait. In preliminary studies,this technology has been utilized to facilitate weight shifting, or loading of the affected limb, for individuals with hemiparesis (Bishop et al., 2017).
