Progressive Achilles-loading program with remote clinician support
Official title: Progressive Achilles Loading Via Clinician E-support (PACE)
Run by University of Iowa · NCT06736795 · Data updated 2026-11-12
This trial tests whether a single telehealth visit plus self-guided exercise and education works as well as multiple telehealth physical therapy visits for adults with Achilles tendon pain.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–60 with localized Achilles tendon pain of at least 3/10 during tendon-loading exercise who have not had recent PT, injections, or contraindicated treatments and who can participate in telehealth are ideal candidates.
✕Probably not a fit
People with partial tendon tears, a history of Achilles rupture, recent injections or shockwave therapy, recent PT for Achilles, certain differential diagnoses (e.g., bursitis, sural nerve neuropathy, plantaris involvement), very high BMI, or ages outside 18–60 are unlikely to benefit from this protocol.

What this trial studies
This single-blind, two-arm randomized non-inferiority trial compares a one-time PT-initiated telehealth visit plus asynchronous exercise and education modules to a standard PT-guided program of six telehealth visits. The study will enroll 160 adults with Achilles tendinopathy across two sites (University of Iowa and Carl R. Darnall Army Medical Center). Primary outcomes are changes in pain and disability, with a secondary aim to identify early patient-reported changes within two weeks that predict four-week improvements. Interventions are focused on progressive tendon-loading exercises and patient education delivered remotely.
Why it matters
Potential benefit: If successful, this approach could expand access to rehabilitation, shorten time to recovery, and help more people—including deployed military personnel—return to full duty faster.
How similar studies have gone: Exercise and education are established treatments for Achilles tendinopathy, but randomized trials directly comparing single-visit, PT-initiated remote programs to multi-visit PT care are limited.
