Identification of Loading Deficits Outside a Research Laboratory

Knee loading deficits such as decreased limb loading, knee extensor moments and power following ACLr are observed across tasks and throughout recovery.  The fact that they are often present in the absence of observable deficits in joint excursions, particularly in early rehabilitation, makes them difficult to detect clinically. Difficulty detecting loading deficits may underlie their long-term persistence. While recent advances in technology may provide less expensive mechanisms for detecting loading deficits it is imperative that we understand how the information provided through technology relates to the deficits we aim to detect.
