Can a strap reduce hip internal rotation during running?

Investigating a new device controlling abnormal hip and knee motion

An increased hip internal rotation is known to be an associated risk factor for running associated injuries, such as patellofemoral pain or non-contact ACL injuries. Researchers in the USA designed a treatment device (‘the Powers strap') to facilitate an external rotation of the femur and thereby control abnormal hip and knee motion during leisure and sport activities. However, research that proves the effect of such a brace is lacking. Thus, this study aimed to investigate whether this device is able to modify hip rotation during the stance phase in running.
