Not Applicable
Terminated
Conditions
Stroke
Interventions
Device: Tibion Bionic Leg
Registration Number
NCT01558232
Lead Sponsor
Tibion Bionics, Inc.
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Ambulation SpeedBaseline (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).

Secondary Outcome Measures
NameTimeMethod
Measurements of StrideBaseline (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.

Measurements of Force, Stance, and StabilityBaseline (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.

Measurements of GaitBaseline (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.
