EMG-biofeedback

Biomechanics gait analysis data. Temporospatial biomechanical parameters were recorded for subsequent evaluation. 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 for each joint in at gait cycle format. The maximum amplitude over GC was recorded in the hip joint (HA, degrees). For the knee joint: first flexion amplitude (Ka1), extension amplitude (Ka2), swing flexion amplitude (Ka3). The maximum amplitude (AA) over GC was analyzed for the ankle joint.
The maximum bioelectric activity of muscles over GC, μV, was recorded in the tibialis anterior (TA), gastrocnemius (GA), quadriceps femoris (QA), and hamstring (HM) muscles.
