Study: NCT01314183

Intervention type: OTHER
Group type: ACTIVE_COMPARATOR
Intervention: Exercise
Description: The program starts with a 10 minute aerobic exercise warm-up (treadmill walking or stationary cycling). Subjects then perform a series of strengthening, stretching, and neuromuscular control activities which are core exercises for the program and mandatory. In addition to the above core exercises, therapists have the option to select additional optional exercise activities, based on the initial examination findings. These exercises will address strength or flexibility in the hip, and ankle if impairments are identified in the initial examination.

Intervention: manual therapy
Description: The manual therapy (MT)techniques are maneuvers that are applied with manual force from the treating therapist. The MT techniques will include a series of accessory motion techniques, manual stretching , and soft tissue manipulation (deep massage to muscles and connective tissues associated with knee function). Core techniques include anterior-posterior and posterior-anterior tibiofemoral translations, superior-inferior and medial-lateral patellofemoral mobilizations, knee flexion and extension mobilizations that may be combined with varus-valgus stresses,medial-lateral tibial rotations, manual stretching of the quadriceps, rectus femoris, hamstring, and gastrocnemius muscles, and soft tissue manipulations of the quadriceps, peri-patellar tissues, hamstring, hip adductors, and gastroc-soleus muscle groups. There are optional MT techniques for the hip, and foot and ankle joints that can be selected by the therapist based on initial examination findings.
