Ankle Muscle Power Program to Help Return to Duty After an Ankle Fracture

Official title: Efficacy and Clinical Feasibility of the Ankle Muscle Power (AMP) Program for Return to Duty After an Ankle Fracture

Run by University of Kentucky · NCT07173088 · Data updated 2026-11-12

This trial tests whether adding ankle muscle power exercises to standard physical therapy helps adults 18–50 recover strength, function, and readiness to return to duty after a surgically fixed ankle fracture.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are English-speaking adults aged 18–50 with an acute surgically fixed ankle fracture, a BMI ≤ 35, and the ability to attend in-person therapy and follow-up visits.

Probably not a fit

Patients with preexisting chronic pain, moderate-to-severe traumatic brain injury, spinal cord injury, multiple trauma preventing participation, current pregnancy, non-English speakers, or those unable to attend in-person visits are unlikely to benefit or be eligible.

What this trial studies

This single-site interventional trial at the University of Kentucky compares two standardized rehabilitation programs after surgical fixation of an ankle fracture: the Ankle Muscle Power (AMP) program plus standard care versus standard care alone. The study will measure feasibility outcomes (adherence, treatment fidelity, recruitment, retention, and acceptability) as well as muscle function outcomes including plantar flexor rate of torque development, ankle power during gait and stair tasks, physical performance tests, and patient-reported outcomes. Researchers plan predefined feasibility targets (for example, 80% adherence and 90% fidelity) to determine whether the AMP program can be scaled into clinical practice. The trial enrolls adults 18–50 years old and requires in-person therapy sessions and follow-up visits.

Why it matters

Potential benefit: If successful, the AMP program could improve ankle strength and power, speed functional recovery, and increase the likelihood of returning to duty after an ankle fracture.

How similar studies have gone: Progressive power-focused rehabilitation has shown benefits in other musculoskeletal settings, but the specific AMP protocol for post-surgical ankle fractures is relatively novel and not yet widely tested.
