In 30 seconds
This pilot randomized controlled trial evaluated the feasibility and effects of lateral wedge insoles (LWIs) in 30 individuals with knee osteoarthritis and foot pain over 12 weeks. The study found that LWIs were safe and well-tolerated, with participants reporting moderate comfort levels. Trends indicated improvements in knee pain and function, as well as knee adduction moments.
Key findings
- Participants reported moderate comfort with insoles, scoring 7/10.
- 83% of participants met the 30-minute daily wear time threshold.
- Trends showed improvement in knee pain and function in both groups.
- No major adverse events were reported during the study.
Why it matters
Understanding the effects of lateral wedge insoles on knee osteoarthritis and foot pain can help clinicians consider non-surgical treatment options that may improve patient outcomes and comfort.
