A Prospective Study to Evaluate Use of the Tibion Bionic Leg in Sub-Acute Post-stroke Patients (Acute Effects)

July 5, 2012 updated by: Tibion Bionics, Inc.

A Prospective, Experimental ABA Study to Evaluate Use of the Tibion Bionic Leg in Subacute Post-stroke Patients Undergoing Physical Therapy

The objective of this clinical study is to examine acute changes in stability, force allocation, work, and mobility from using a wearable, portable, battery-operated robotic orthosis (the Tibion Bionic Leg) in subacute post-stroke persons undergoing lower extremity physical therapy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Tibion Arm
Arm of the study in which enrolled subacute post-stroke subjects undergo lower extremity physical therapy using the Tibion Bionic Leg.
Device: Tibion Bionic Leg
The Tibion Bionic Leg is used as an adjunct in post-stroke and post-operative rehabilitative physical therapy. The leg is a lightweight, wearable, portable, battery-powered, motorized leg orthosis that provides active assistance and resistance to lower limb movement during walking, stair ascent and descent, and transfers from sitting to standing (and standing to sitting).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ambulation Speed
Time Frame: Baseline (prior to training); at conclusion of training regimen, an average of 2 weeks.
Walking speed (comfortable and fastest possible), in meters per second, as measured by the 10 Meter Walk Test (10 MWT).
Baseline (prior to training); at conclusion of training regimen, an average of 2 weeks.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measurements of Gait
Time Frame: Baseline (prior to training); prior to the first training session; prior to the second training session; at the conclusion of training regimen completed an average of 2 weeks.

The secondary endpoints are obtained from the GAITRite analysis system:

  • Measurements of gait, such as the length and time of step, cycle, and stride, Heel to Heel base support, single/double limb support time, and stance and swing phase timing.
Baseline (prior to training); prior to the first training session; prior to the second training session; at the conclusion of training regimen completed an average of 2 weeks.
Measurements of Stride
Time Frame: Baseline (prior to training); prior to the first training session; prior to the second training session; at the conclusion of training regimen completed an average of 2 weeks.

Other secondary endpoints are obtained from the GAITRite analysis system:

  • Measurements of Stride such as distance, ambulation time, velocity, normalized velocity, cadence, step time, step length, cycle time.
Baseline (prior to training); prior to the first training session; prior to the second training session; at the conclusion of training regimen completed an average of 2 weeks.
Measurements of Force, Stance, and Stability
Time Frame: Baseline (prior to training); prior to the first training session; prior to the second training session; at the conclusion of training regimen completed an average of 2 weeks.

Other secondary endpoints are obtained from Balance Master system:

  • Limb parameters, including force in transfers from sitting to standing, standing to sitting, weight-bearing squats, and limits of stability.
Baseline (prior to training); prior to the first training session; prior to the second training session; at the conclusion of training regimen completed an average of 2 weeks.
