Foot position during Achilles tendinopathy rehab
Official title: The Effect of Foot Positioning During a 12-week Supervised Training Program on Achilles Tendon Mechanics and Function in Individuals With Mid-portion Achilles Tendinopathy.
Run by KU Leuven · NCT07623408 · Data updated 2026-11-12
This trial tests whether doing a 12-week load-based exercise with a toes-out foot position helps the Achilles better heal and function compared with a neutral foot position in adults with mid-portion Achilles tendinopathy.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18-65 with a history of Achilles tendinopathy, tendon thickening on palpation, pain during loading, and sonographic evidence of tendinopathy.
✕Probably not a fit
Individuals without mid-portion Achilles tendinopathy or without the specified clinical and imaging findings may not benefit.

What this trial studies
Participants with mid-portion Achilles tendinopathy will follow a 12-week adaptive exercise program focused on load progression. The study compares an externally rotated (toes-out) foot position to a neutral foot position to see how intra-tendinous sliding, symptoms, and function change, while daily activity is tracked to relate loading patterns to recovery over six months. The aim is to understand whether foot positioning during rehabilitation influences tendon mechanics and patient outcomes. Achilles tendinopathy is common and rehabilitation outcomes vary; this study seeks to optimize exercise therapy by examining tendon sliding and loading during recovery.
Why it matters
Potential benefit: If successful, the approach could improve pain, function, and return-to-activity for people with Achilles tendinopathy.
How similar studies have gone: Prior work suggests foot position can influence tendon sliding, but this specific 12-week adaptive protocol is novel in testing its effect on clinical outcomes.

Show full inclusion / exclusion criteria
The following inclusion criteria will be used: PATIENTS WITH ACHILLES TENDINOPATHY: * Voluntary written Informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures. * Age between 18 and 65 years old * BMI between 18.5-30 * Showing history of intermittent episodes of Achilles tendon pain lasting more than 3 consecutive weeks within the past 6 months. * Presenting palpable focal thickening of the Achilles tendon. * Having pain originating from the Achilles tendon on palpation of thickened tendon and on loading activities (such as running, jumping). * Showing sonographic evidence of tendinopathy, i.e. focal thickening and hypoechocity, consistent with previously reported sonographic characteristics diagnosed of tendinopathy. Prior to start of the data collection, these inclusion criteria (specifically the ones concerning Achilles Tendinopathy presence) will be checked by a medical doctor at SMAC (Sports medical advisory centre Leuven). Only if they confirm the diagnosis, patients are included in the study.
