How orthotics and foot exercises change the biomechanics of hallux valgus (bunions)
Official title: A Study on the Biomechanical Mechanisms of Orthotic/Physical Training Correction of Hallux Valgus and Its Impact on the Lower Limbs
Run by Southern Medical University, China · NCT07036120 · Data updated 2026-11-12
This project will test whether wearing orthotics or doing foot exercises for 12 weeks can change how the foot and lower limb move in people aged 18–45 with bunions.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18–45 with bilateral hallux valgus (hallux valgus angle >15°), right-leg dominant, with no lower-limb surgery or neuromuscular gait disorders and no treatment for hallux valgus in the prior 3 months.
✕Probably not a fit
People older than 45, those with unilateral hallux valgus, recent treatment for the condition, prior lower-limb surgery, or neuromuscular disorders causing gait abnormalities are unlikely to benefit from this specific protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The project enrolls mainly young adults with bilateral hallux valgus and assigns them to 12-week interventions using either orthoses or targeted foot exercises. Researchers will record kinematic and kinetic data with motion capture, measure muscle activity with surface electromyography, and image soft tissues with musculoskeletal ultrasound before, during, and after stopping the interventions. The protocol compares changes over time and between intervention groups and builds a database of in vivo biomechanical characteristics for this population. Outcomes focus on how conservative treatments alter foot and lower-limb mechanics rather than surgical endpoints.
Why it matters
Potential benefit: If successful, the findings could help tailor conservative therapies to improve foot alignment and walking mechanics and potentially reduce symptoms and progression in young adults with hallux valgus.
How similar studies have gone: Previous small biomechanical studies have shown that orthotics and foot exercises can change foot mechanics, but large-scale or long-term clinical outcome data are still limited.
