Brief Summary
This study will be the first project to evaluate the effectiveness of wearable technology (Garmin Forerunner35) while performing gait retraining in field on military members. The watch will provide real time feedback to the runner on their step rate while performing running sessions outside of the lab. This allows the runner to modify their step rate to meet a recommended step rate provided by the study team member. Aim 1: To demonstrate the utility of wearable sensors to modify running step rate through real time biofeedback. Aim 2: To determine whether altering step rate using real time biofeedback reduces lower extremity musculoskeletal injury reoccurrence within 1 year post training.

Outcome Measures
Primary Outcomes (3)
Change in Average vertical loading rate (AVLR)
The slope of the line on a ground reaction force curve from initial contact to the impact peak
Baseline, 10 weeks, 6 months
Change in Step rate (SR)
The number of steps a participant takes per minute of running
Baseline, 10 weeks, 6 months
Injury
The number of lower extremity, over-use injuries sustained within 1 year after completing the ten in-field training sessions
1 year
Secondary Outcomes (2)
Absolute risk reduction
1 year
Limited duty days
1 year
Study Arms (2)
Retraining (RT) Group
EXPERIMENTALThe retraining group will receive a watch accelerometer to use for monitoring their step rate with instructions to increase their preferred step rate by 7.5% over the ten in-field training sessions.
Control (CON) Group
NO INTERVENTIONThe control group will receive the same device to monitor their pace but receive no instruction to change their preferred step rate over the ten in-field training sessions.
Interventions
Running step rate will be retrained by real-time biofeedback via a watch accelerometer. Recent literature showed that performing gait retraining by altering step rate reduces loading rates and joint stress that are associated with lower extremity injuries (Wilson et al 2014, Lenhart et al 2014, Heidersheit et al 2011).
Eligibility Criteria
You may qualify if:
- Between the age of 18 - 50 years
- Active Duty, Department of Defense beneficiaries
- History of running-related overuse, musculoskeletal injury of the lower extremity (knee, hip, lower leg, or bone stress injury) within the last six months
- Currently able to run continuously for at least 15 minutes at self-selected pace, 3 times per week.
- Read and speak English well enough to provide informed consent and follow study instructions
You may not qualify if:
- Known pregnancy currently or in the previous 6 months
- Lower extremity or low back surgery in the previous 6 months
- Any lower extremity or low back exercise profile that limits running
- Participant has already completed a step rate, gait retraining program
- Participant has a step rate greater than 176 steps per minute
