The visual feedback will allow patients to instantly see what is happening while working on the given task, perhaps most importantly, without thinking of every little thing in the meantime. The visual external que is intuitive, and while verbiage like “squeeze here, push back here, lock it in…” can be helpful, things are much more simple, and simple is good.
I instructed the patient “remember how it felt while you were working with that laser pointer? Just try make your knee act the same way whenever you think on it.” If between session results offer diminishing returns, the Motion Guidance “patient packs” are definitely an option as DME for HEP.
Difficulty getting full extension is ubiquitous across the majority of surgical procedures on the knee (ACL, TKA, etc…), so if you are looking for a novel way to improve in this area, consider visual feedback external cues.
