Purpose

The goal of this clinical trial is to compare two different standardized physical therapy rehabilitation programs on outcomes after an ankle fracture. Researchers will evaluate to see if the addition of ankle muscle power exercises (AMP) improve program adherence, muscle function, physical performance, and patient reported outcomes. The main questions it aims to answer are: 1. Assess feasibility and define the initial effects of the AMP program on ankle plantar flexor rate of torque development and ankle power. Primary hypothesis: an ankle muscle power program will have acceptable feasibility through assessment of 80% adherence, 90% treatment fidelity, recruitment (48 participants who complete the study), 80% retention, and 80% acceptability of the AMP program to facilitate clinical translation and the ability to scale-up the treatment. In addition ankle plantar flexor muscle power, plantar flexor RTD assessed isometrically, and ankle joint power, evaluated during gait and stair ascent/descent, will have significantly greater improvements in the AMP group than the standard of care group at the end of the intervention. 2. Test the effect of the AMP program on physical performance. Primary hypothesis: those completing the AMP program will have greater improvements in the 40 meter fast paced walk test and 11-stair climb test than those completing standard of care at the completion of the intervention. 3. Assess the preliminary efficacy of the AMP program on patient reported outcomes and quality of life. Primary hypothesis: compared to standard of care, the AMP program will result in improved quality of life on the ankle fracture outcome rehabilitation measure (A-FORM) Participants will complete rehabilitation and be assessed for outcomes at baseline and after completing the intervention. Additionally exploratory outcomes will be assessed 3 months after completing the intervention.

ArmDescriptionAssigned Intervention
Experimental
Ankle Muscle Power (AMP) program + standard of care 		Participants will receive standard of care rehabilitation as needed and directed by the treating physical therapist. Participants will have additional exercises included to facilitate the development of power that will progress as participants move through the rehabilitation program. The intervention may begin approximately 12 weeks post op ± 2 weeks following fixation surgery and will have visits for up to 12 weeks with an average of 3 visits per week.
  • Other: Ankle Muscle Power (AMP) program
    The AMP program targets various aspects of muscle power development through a program that takes the participant through 3 different stages of training over the course of their rehabilitation. This portion of the program is in addition to receiving standard rehabilitation exercises as well.

Active Comparator
Standard of care only 		Standard of care rehabilitation includes range of motion, foundational strength exercises, and other modalities (i.e., icing and or low grade NMES) as needed and directed by the treating physical therapist. The intervention may begin approximately 12 weeks post op ± 2 weeks following fixation surgery and rehabilitation will take place for up to 12 weeks with visits occurring 3 times per week on average.
