What this Trial Is About
Researchers are evaluating a home-based leg dexterity training program to reduce pain and improve function in adults with knee osteoarthritis (OA). This condition affects millions of older adults, causing pain and mobility issues. The study compares a new device, the Leg Dexterity System, designed to train neuromuscular control, against a commonly used wobble board exercise to see which better helps manage knee OA symptoms. The trial is a randomized, double-blind study involving 82 participants aged 40 to 85 years. Participants are randomly assigned to one of two groups: one uses the Leg Dexterity device, a portable system where seated users compress a spring platform to train leg control; the other uses a wobble board with safety rails for balance exercises. Both groups perform 10-minute training sessions three times a week for eight weeks at home. The sessions are guided and logged with a tablet-based app. Initial training and assessments occur at the research institute, with follow-up testing after the 8-week training period. Participants will be assessed before and after the training on knee pain using a numerical rating scale and the WOMAC pain and function scores. Additional measures include standing balance, physical function tests, gait analysis, and quality of life surveys. The study lasts about 10 weeks per participant, including baseline and follow-up visits. Researchers will monitor training adherence, safety, and the impact of the exercises on knee function and overall mobility.
