Game-Based Foot & Ankle Exercise for Those With Lower Extremity Edema
A Game-based Foot & Ankle Exercise Program to Increase Efficacy Of Compression Garments At Managing Edema
Study Overview
Status
Intervention / Treatment
Detailed Description
Lower extremity edema (LE) is an accumulation of interstitial fluid volume in the legs and feet and commonly occurs in patients with diabetes, hypertension, kidney disease, heart failure, cirrhosis, cancer, and obesity. LE can also result from deep vein thrombosis (DVT) in the lower leg. Compression socks or garments are often used to decrease this edema. Despite the efficacy of this treatment, there are some limitations including low patient compliance and contraindication of high compression levels for patients with high grades of peripheral arterial disease. Given that it is has previously been shown that exercise can be a positive way to reduce LE, the present study aims to use a game-based exercise program to help increase patient's movement and thus improve efficacy and adherence to the compression garments/socks.
The investigators will recruit 30 participants and randomly divide them into two groups: Active Group (AG) and Control Group (CG). Both groups will receive a compression garment (CompreCares) developed by Medline Incorporated(Inc). (IL, USA). The AG will receive a tablet and foot sensor (TEXASSENSE INC, USA), and will be instructed to play with it daily for 5 minutes over the period of 4 weeks.
During the two study visits (BL and W4), the investigators will assess the following outcomes: calf muscle activation (assessed by surface electromyography [sEMG]), foot perfusion (SNAPSHOT NIR, Kent Imaging System), calf and foot circumference, ankle-brachial index (ABI), pitting edema test, foot volume, gait, balance, and peripheral neuropathy (DPNCheck, Neurometrix Inc., Woburn, Massachusetts, USA).
Acceptability and patient reported outcomes will be assessed via validated questionnaires collected at each study visit.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Active group (AG)
Active group (AG).
The AG (n=15) will play game-based foot and ankle exercises via a mobile application on a tablet.
They will be asked to wear a foot sensor that is connected to the tablet during the exercise.
They will be asked to play the game for 5-minutes, daily.
They will do this in conjunction with wearing a compression garment for a period of 4 weeks.
|
Patients in the active group will put on a sensor connected to a tablet to play a game-based foot/ankle exercise twice a day for 5 minutes for four weeks.

|
No Intervention: Control group (CG)
Control Group (CG).
The CG (n=15) will wear a compression garment for four weeks.
