Experimental Treatment A Then B
Subjects will receive two treatments: (1) a non-invasive external Cutaneous Stimulation device placed on the leg of the subject consisting of a sensing module to determine specific points in the gait cycle, a processor to analyze signal from the sensor, and a stimulus module to provide feedback (vibration) to the subject and (2) a commercially-available knee sleeve, separated by a washout period. Cutaneous Stimulation: A non-invasive external device that will be placed on the leg of the subject. The device consists of a sensing module to determine specific points in the gait cycle, a processor to analyze signal from the sensor, and a stimulus module to provide feedback to the subject. Knee Sleeve: Commercially-available Passive Knee Bands.

PRIMARY outcome

Timeframe: Baseline and 4 week follow-up

Population: Participants completing the study protocol.

Within-subject change (follow-up - baseline) in peak knee flexion moment (%Bodyweight\*Height) with the intervention at 4-week follow-up versus control (without the intervention) at baseline.

SECONDARY outcome

Timeframe: Baseline and 4 week follow-up

Population: Participants completing the study protocol.

Within-subject change (follow-up - baseline) in pain (KOOS sub-scale) with the intervention at 4-weeks versus control (without the intervention) at baseline. KOOS scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems.
