Biofeedback Stroke Stance Phase and Single Support Phase

Temporal parameters included gait cycle (GC) duration, sec; Cadence or stride rate, steps/min; foot clearance (Cl), cm; walking speed (V), km/h; stride length (SL), cm. Individual time periods of GC (measured as % from GC): stance phase (SP), single support phase (SSP), and the total period of double support phase (DSP).
Recording of kinematic parameters was carried out from the joints of the lower ex-tremities: hip, knee, and ankle in the sagittal plane (flexion – extension). The software automatically generated goniograms (a function of angle versus time) for each joint in a standard gait cycle format. The maximum amplitude over GC (HA, degrees) was recorded in the hip joint. For the knee joint: first flexion amplitude (Ka1), extension amplitude (Ka2), swing flexion amplitude (Ka3). Only the amplitude (AA) over GC was analyzed for the ankle joint.
