In HIIT an individual gives short bursts of high effort followed by a longer recovery period.
Increasingly, HIIT style training programs have been used in other clinical populations (heart conditions, kidney failure, severely obese) to yield improved health outcomes and have been shown to be safe and effective. However, this work has not been extended to the orthopedic trauma population. Initiating a treadmill HIIT program during recovery from a lower extremity fracture may prove pivotal to restoring functional abilities, improving strength, and optimizing patient outcomes.
As a starting point to investigate the speed HIIT walking program following an orthopedic trauma, the investigators will focus on femoral and tibial shaft fractures requiring surgical fixation. Subjects will be recruited at a follow-up visit and therefore will not have impaired consent capacity issues at that juncture based on their fracture-related injuries. Even though early postoperative weight bearing has been shown to be safe, there continues to be considerable divergence in recovery after these fractures. For instance, return to work rates for individuals with physical jobs has been reported to be as low as 14% within the first year, resulting in significant stress and financial challenges for the individual. Clearly, improved post-operative rehabilitation strategies are needed for this population.
Aim 1: Assess the feasibility and adherence of the speed HIIT walk program within subjects with a lower extremity fracture.
Primary Hypothesis: 70% of subjects approached about the study will consent and that 80% of subjects will complete the study.
Secondary hypothesis: 80% of subjects will complete all of the treatment sessions and find the treatment (both intervention and standard of care physical therapy) acceptable.
Aim 2: Determine the preliminary effects of the speed HIIT program as compared to the standard of care on patient reported outcomes, functional outcomes and return to work rates, in a pilot randomized control trial.
Primary Hypotheses: Participants in the speed HIIT intervention group will have a significantly higher PROMIS physical function scale as compared to standard of care group at a 6 month follow up.
Secondary hypotheses: Participants in the Speed HIIT intervention group will have higher return to work rates, usual and fastest gait speed, timed step-down test, and 6-minute walk test than the standard of care group at a 6 month follow up.
Tertiary hypothesis: The participants in the speed HIIT program will maintain higher physical function and return to work rates at a 12 month follow up as compared to the standard of care group
Aim 3: Quantify the differences in ground reaction forces, function, psychosocial responses, and patient reported outcomes that occur at the completion of the speed HIIT walk program as compared to the group receiving standard of care physical therapy.
Primary Hypotheses: Participants in the speed HIIT program will be significantly more symmetric in their peak ground reaction force metrics (impulse, loading rates, time, peak values), and have greater self reported physical function, functional outcomes and patient reported outcomes as compared to the standard of care group at the completion of the intervention (19 weeks post hospital discharge).
Secondary hypotheses: Participants completing the speed HIIT program will have greater pain self-efficacy and less fear of movement as compared to the standard of care at the completion of the intervention (19 weeks post hospital discharge) that is maintained at a 6 and 12 month follow up.
Tertiary hypothesis: The participants in the speed HIIT program will maintain higher symmetry in their peak ground reaction force metrics (impulse, loading rates, time, peak values) as compared to the standard of care group at a 6 month follow up.

Standard of care will follow best practice. The subjects and their physical therapists will be provided with a standardized set of exercises and guidance on what to cover during skilled physical therapy visits. As part of the study, all patients will receive the same exercise program. Exercises will include lower extremity strengthening, balance, and mobility exercises with the use of modalities as needed
The 4-6 week program will consist of a warm up of active stretching. Following the warm up, subjects will perform a 2 minute warm up followed by 1 minute of walking at their fastest comfortable speed followed by 2 minutes of active recovery where they will walk at a speed of their choosing for 4cycles and then a 2 minute cool down. The program will be performed 12 visits over 4-6 weeks.
Time frame: Up to 12 weeks

Standing on an 4-inch box, participants will step down until the heel gently touches a scale placed on the ground and then return to full knee extension. As many repetitions as possible in 60 seconds will be recorded. Repetitions with over 10% of the body weight registered on the scale will not be counted toward the total number of repetitions completed. The test has previously been shown to have a high interrater reliability of 0.94 and was associated with a change in knee mechanics following an orthopedic surgery.
Interpretation: More successful repetitions indicate greater neuromuscular control and muscle strength in the lower extremity.

The Pain Self-Efficacy Questionnaire (PSEQ) is a 10-item questions and will be used measure an individual's beliefs about their ability to participate in social activity and accomplish their goals despite the presence of pain. PSEQ has demonstrated excellent internal consistency, test-retest reliability, and construct validity.
Interpretation: Greater self-efficacy (higher survey score) is related to reductions in disability, pain intensity, fear of movement and pain, and affective distress in patients with chronic pain.
