A programmable, carbon-fiber robotic leg orthosis (Tibion Bionic Leg, Tibion Corporation, Sunnyvale, CA) was used during therapy to actively supplement concentric and eccentric quadriceps function on the participant's impaired side. The device uses internal sensors at the foot and knee joint to detect intention of movement and, once a variable force threshold is passed, the devices provides appropriate assistive and resistive adjustments.

Ambulation Speed
Ambulation speed, in meters per second, as obtained by the Ten (10) Meter Walk Test (10 MWT). The 10 MWT measures the time required to walk 10 meters at the subject's comfortable walking pace.
Time frame: Baseline (prior to training); at conclusion of 4 week training regimen (1.5 hours/session with 2 to 4 sessions per week); and 1 Month post-training regimen.
6 Minute Walk Test (6 MWT)
The total distance walked by the patient, in meters, as obtained by the Six (6) Minute Walk Test (6 MWT). The 6 MWT is performed over level ground, using any walking aids (canes, walkers, etc.) the patient requires for comfortable walking.
Time frame: Baseline (prior to training); at conclusion of 4 week training regimen (1.5 hours/session with 2 to 4 sessions per week); and 1 Month post-training regimen.
Timed Up and Go (TUG) Test
The time, in seconds, for the patient to rise from sitting in a standard arm chair, walk 3 meters, turn around, walk back to the chair, and sit down. This evaluation is called the Timed Up and Go test (TUG). The patient may wear their usual footwear and use any aids (canes, walkers, etc.) they typically employ for comfortable walking.
Time frame: Baseline (prior to training); at conclusion of 4 week training regimen (1.5 hours/session with 2 to 4 sessions per week); and 1 Month post-training regimen.
Five Times Sit to Stand Test (5 x STS)
The time, in seconds, for the patient to rise from a seated to full standing position and return to sitting five times in rapid succession. This evaluation is called the Five Times Sit to Stand Test (5 x STS)
Time frame: Baseline (prior to training); at conclusion of 4 week training regimen (1.5 hours/session with 2 to 4 sessions per week); and 1 Month post-training regimen.
Step Length

The length of the patient's average step, in meters, as measured during comfortable walking.
Time frame: Baseline (prior to training); at conclusion of 4 week training regimen (1.5 hours/session with 2 to 4 sessions per week); and 1 Month post-training regimen.
