Orthofeet: A Prospective Proof of Concept Trial to Evaluate an Innovative Pain Relief Footwear

Study Overview
=================
Brief Summary
-----------------
The purpose of this prospective proof of concept study is to examine the effectiveness of a new pain relief footwear (Orthofeet) on function and daily activities. he investigators hypothesize that Orthofeet will reduce foot pain leading to an increase in daily physical activities, measured objectives using validated wearables (PAMSys and Garmin wristwatch), and functional performance (gait and balance). In addition, the investigators hypothesis that reduction in foot pain is associated with reduced physiological stress response (HRV) and better community engagement (assessed by life space questionnaire).

Detailed Description
-----------------
A clinical study at the Baylor College of Medicine, to evaluate short and intermediate benefits and effectiveness of a novel pain relief footwear, called Orthofeet. This is a randomized crossed over trial. The duration of the study would be 12-week. The investigators will recruit 50 eligible ambulatory adults (age 50 years or older) with moderate to severe self-reported foot pain. Participants will be randomly assigned to Group A (25 subjects) and Group B (25 subjects). There is no difference in assessments or eligibility between Group A and Group B, the only difference is when they have the opportunity to try the shoes for 6 weeks. Group A will receive a pair of Orthofeet shoes with adjustable insoles and will be asked to wear it every day activities of daily living for duration of six weeks. Participants will be also encourage to wear the shoes inside of home if possible. Group B will be followed for duration of six weeks. At six weeks the groups will be switched and group B will receive and a pair of Orthofeet shoes with adjustable insoles and Group B will follow-up for six week without Orthofeet shoes. Participants will be assessed at baseline, week-1, week-6, week 7, and week 12.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Foot Pain Intensity | Changes in foot pain from baseline to 12 weeks will be assessed by Foot Function Index (FFI) questionnaire. Score ranges from 0 to 230, the higher the score indicates greater disability/decreased foot function. | baseline, 1 week, 6 weeks, 7 weeks, 12 weeks | 
| Change in step count from baseline to 6 weeks to 12 weeks | Step count will be measured over the course of 12 weeks using a smart watch (Vivosmart 4, Garmin, USA) | 12 weeks from baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Physical Activity | Changes in physical activity from baseline to 12 weeks will be assessed. Physical activity will be quantified by measuring number of taken steps per day and will be measured using a validated wearable sensor named PAMSys. Monitoring of physical activity will be done during 48hours at baseline, 6 weeks, and at 12 weeks. | baseline, 6 weeks, and 12 weeks | 
| Change in Quality of Life | Quality of life will be assessed using a validated questionnaire, called PROMIS Global-10. The PROMIS Global-10 is a 10-item patient-reported questionnaire in which the response options are presented as 5-point (as well as a single 11-point) rating scales. The results of the questions are used to calculate two summary scores: a Global Physical Health Score and a Global Mental Health score. These scores are then standardized to the general population, using the T-Score. The average T-Score for the United States population is 50 points, with a standard deviation of 10 points. Higher scores indicate a healthier patient. | baseline, 6 weeks, and 12 weeks | 
| Change in Gait speed | Change from baseline in Gait speed at 12 weeks. Gait speed will be measured using a validated wearable platform (LEGSys) during habitual walking speed. | baseline, 6 weeks, and 12 weeks | 
| Change in Balance | Change in balance from baseline to 12 weeks will be measured. Balance will be assessed by measuring center of mass sway. The investigator will use a validated wearable platform (BalanSen) to measure body sway. | baseline, 6 weeks, and 12 weeks | 
| Change in Fear of Falling | Changes in Fear of falling will be assessed by Short Falls Efficacy Scale International (FES I) questionnaire at 12 weeks and will be compared to baseline measurements. Scores range from 16 to 64, the higher the score the more concerned the subject is with falling. | baseline, 6 weeks, and 12 weeks | 
| Change in Cognitive Function | Changes from baseline in cognitive function at 12 weeks. Cognitive performance will be assessed using Montreal Cognitive Assessment (MoCA). Scores on the MoCA range from zero to 30, with a score of 26 and higher generally considered normal. | baseline, 6 weeks, and 12 weeks |
