Outcome Measures

Primary Outcomes (21)

  • Muscle strength by Oxford scale

    Testing key muscles from the lower extremities (muscle rectus femoris, muscle biceps femoris, muscle gastrocnemius, lateral head, muscle tibialis anterior) against the examiner's resistance and grading the patient's strength on a 0 (No contraction) to 5 (Movement against gravity with full resistance) scale.

    Baseline

    The average maximum pressure reached in N/cm² for the three zones: toes, mid-foot and heel (left and right legs separately).

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Time maximum force (percentage of stance time)

    The change of the average point in time within a gait cycle where the maximum values for the three zones: toes, mid-foot and heel were collected in Newton.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Contact time (percentage of stance time)

    The average contact time change of the three zone toes, mid-foot and heel as a percentage.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Length of the gait line (millimeters)

    The change from baseline of the progression of the center of pressure of all the steps recorded of one side of the body (left and right side of body separately).

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Anterior/Posterior Position (millimeters)

    The shift change forwards or backwards of the Center of pressure.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Lateral symmetry (millimeters)

    The change from baseline of the left /right shift of the center of pressure, taking all the steps into consideration. A negative value indicates a shift to the left, and a positive value, a shift to the right.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Step time (seconds)

    Time change during the phase within a gait cycle between the heel contact of one side of the body and the heel contact of the contralateral side.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Cadence (steps/minutes)

    Change from baseline of step frequency.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Velocity (kilometers/hour)

    Average gait speed change from baseline during the analyzed measuring interval (30 seconds).

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Stance phase (percentage)

    The phase of a gait cycle change in which the foot has contact with the ground.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Swing phase (percentage)

    Change from baseline of the phase of a gait cycle during which the foot has no contact with the ground.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Double stance phase (percentage)

    The phase change from baseline during a gait cycle that begins at contralateral initial contact (when the heel of the contralateral side touches the ground) and ends at toe off of the viewed side of the body.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Foot rotation (degree)

    The change from baseline of the angle between the longitudinal axis of the foot and the walking direction.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Step length (centimeters)

    Change of the distance between the heel contact of one side of the body and the heel contact of the contralateral side.

    Baseline, approximately 2 days before the end of acute rehabilitation

  • Gait analysis with surface electromyography: Stride length (centimeters)

Study Arms (1)

Gait and balance measurement

OTHER

Gait analysis with surface electromyography measurement: surface electromyography signals (of affected and non-affected legs), gait and stance parameters are collected while the patient walks for 30 seconds on the treadmill with integrated sensor equipment (for measuring the force distribution). Balance analysis with Biodex balance system SD: measurements of postural stability, fall risk, limits of stability, sensory integration are collected.

Device: Gait and balance measurement

Interventions

Virtual gait training procedures are included. Balance training procedures with Biodex Balance system are included too.
