The present study aims to use a game-based tele-exercise program for patients using a compression garment to improve lower extremity edema. This tele-exercise gaming platform can work as an efficient exercise to improve patients' muscle strength. It also can be helpful in improving edema and venous return and can be used in addition to compression garments to increase efficacy. The sample size (n=30) is convenient and designed to explore acceptability and feasibility. Eligible participants will be screened at the Baylor college of Medicine Clinic based on the inclusion/exclusion criteria. Participants who satisfy the inclusion and exclusion criteria and sign the informed consent form will be randomly assigned with ratio of 1:1 into two groups. Both groups will receive a compression garment to use for 4 weeks, and in the intervention group, patients will receive a sensor and a tablet to play foot & ankle exercise games twice a day for 5 minutes. Study participation will be 4 weeks for all participants. Participants will be assessed in two visits: a baseline visit (BL) and a visit at the end of the 4 weeks (W4). The primary outcomes will be calf circumference, foot volume, and pitting edema grade. Secondary outcomes include limb strength, foot perfusion, gait assessment (gait speed, stride length, double stance, and gait steadiness), balance, and quality of life. The coordinator will monitor patients weekly to see their adherence to the compression garment and game-based exercise.

Other | Change in peripheral neuropathy from baseline to 4 weeks | Peripheral neuropathy will be assessed using DPNCheck (Neurometrix, Woburn, MA, USA). This is a noninvasive device which will measure conduction velocity and amplitude. | 4 weeks from baseline | |
Other | Patient acceptance at 4 weeks | Participant acceptance of the tele-exergaming program will be assessed at the end of their participation using a validated technology acceptance model (TAM) questionnaire | 4 weeks from baseline | |
Other | Change in physical activity (step count and intensity minutes) from baseline to 4 weeks | Physical activity metrics, such as step count and intensity minutes, will be measured over the course of the 4 weeks using a smart watch (Vivosmart 4, Garmin, US) | 4 weeks from baseline | |
Primary | Change in calf circumference from baseline to 4 weeks | Calf circumference will be assessed with a soft measuring tape for each leg | 4 weeks from baseline | |
Primary | Change in foot circumference from baseline to 4 weeks | Foot circumference will be assessed with a soft measuring tape for each leg | 4 weeks from baseline | |
Primary | Change in foot volume from baseline to 4 weeks | Foot volume will be assessed with a standard foot volumeter | 4 weeks from baseline | |
Primary | Change in pitting edema grade from baseline to 4 weeks | Coordinators will press on the affected area in the lower extremities and measure depth of indention. They will record the length of skin rebound time and grade the edema based on validated scales | 4 weeks from baseline | |
Secondary | Change in gastrocnemius muscle strength from baseline to 4 weeks | Lower extremity strength will be assessed with an ankle dynamometer and surface electromyography (Delsys Trigno Wireless EMG System, MA, US). | 4 weeks from baseline | |
Secondary | Change in gait and balance from baseline to 4 weeks | Gait speed will be measured with standard walking tests and wearable sensors (Legsys). | 4 weeks from baseline | |
Secondary | Change in balance from baseline to 4 weeks | Static balance will be measured with standard balance tests and wearable sensors (Balansens). | 4 weeks from baseline | |
Secondary | Change in plantar tissue oxygen saturation/consumption from baseline to 4 weeks | Percentage of tissue oxygen saturation (SatO2) and hemoglobin values will be measured using a validated near-infrared (NIR) camera (Snapshot NIR, KENT Imaging Inc., Calgary, AB, Can) that detects an approximate value of real-time SatO2 and level in superficial tissue. The area that will be captured is the metatarsus area | 4 weeks from baseline |
