AlterG ACL Return to Running Case Series

This case series will follow standard ACL protocol, while using biomechanical movement analysis to analyze running mechanics using a body weight supported treadmill. Standard ACL protocol will be followed throughout the treatment of each patient. The only variance from treatment will be using motion analysis software to analyze gait patterns at different points throughout the rehabilitation. The first motion analysis will be performed at week 6 of the rehabilitation process. Prior to this treatment, manual muscle testing of the hip, knee and ankle using a handheld dynamometer, two outcome measures, range of motion, pain, and patient satisfaction will be performed. At this treatment, motion capture sensors will be placed on the patient at different anatomical positions. The patient will then run in a body weight supported treadmill. During this run, video capture will be performed and later analyzed to determine biomechanical kinematics. This process will be repeated at week 8 of rehabilitation in the body weight supported treadmill. At week 10, the patient will shift treatment from the body weight supported treadmill, to a standard treadmill. The process will be repeated using the same anatomical landmarks and video capture. The final video capture will be performed at week 12. At this visit, video capture will be performed. The patient will also repeat all test, measures, and questionnaires from week 6. At all visits between video capturing, standard PT will be performed with a focus on patient deficits and following the standard protocol.
