There have been 2 opposing views concerning the influence of movement variability in injury. On one hand, some authors postulate that reduced variability imposes repetitive load in the same musculoskeletal structures, predisposing them to injury.
On the other hand, a different train of thought suggests that excessive variability may be associated with injury as it represents abnormalities in motor control. The latter perspective has been supported by several studies on different lower limb injuries.
This review included 22 studies about the influence of movement variability on different lower limb injuries. Study quality and risk of bias were assessed through the modified Downs and Black’s checklist.
