3 Clinical Trials for Various Conditions
The investigators will conduct a controlled clinical trial with U.S. Army soldiers training to become combat medics. The purpose of this study is to determine if a 11-week, high intensity exercise program targeting the low back muscles using specialized equipment will result in a 25% increase in low back muscular strength and endurance compared with a lower intensity general core stability exercise.
Back injuries are the most common reason people seeking for effective treatment. One of the most common treatments in sports medicine for muscular injuries is therapeutic ultrasound, which is designed to heat the injured tissue and increase the flow of blood to promote healing.
The purpose of this study is to gain a better understanding of the effects of lumbopelvic manual therapy on lower extremity biomechanics and arthrogenic muscle response. As a result of this study, we also hope that physical therapists, athletic trainers, and other physical medicine rehabilitation providers will gain a better understanding of lower extremity injuries and have the scientific evidence to provide patients with techniques which would allow for efficient return to activities of daily living without restrictions and possibly prevent future injuries and minimize risk of osteoarthritis. The objectives of this study are to: * Determine the amount and duration of arthrogenic muscle response of quadriceps muscles following lumbopelvic joint manipulation. * Determine the effects of lumbopelvic joint manipulation on temporospatial parameters of gait such cadence, step length, velocity and mean peak lower extremity joint moments. * Determine if a correlation exists between patellofemoral joint pain and lumbopelvic joint dysfunction. * Determine the amount of change in clinical outcome measure scores following lumbopelvic joint manipulation.
