Eli has been dealing with a chronic knee pain and instability from an injury 3 years ago when he heard a “pop” while landing a front-flip. Eli experiences pain and an unstable feeling with activities like hiking downhill. He stated he has “always had a limitation since the injury.”
….big improvement in ability and confidence in my knee. It still gets sore after being on it all day working. Still not 100% but a very noticeable improvement. Thanks again!” Eli’s response after 1 session in the Performance Lab.
The hallmark of any knee pain or ongoing injury is delay (in the firing of the muscles) and poor muscle recruitment. This delay and poor muscle recruitment shows up in the video in the before segment, where Eli is not able to control the board while balancing on his left foot. In the after segment, he is able to control it because delay is reduced and muscle recruitment increased. This change will allow the knee to start healing which is why after just 1 session he saw the results he states above.
Stepping up and down on a chronically injured knee can be difficult at best. The pain and instability steal the confidence and compensations naturally come in. What I primarily want to see is if Eli has the inability to lift up onto the leg on the step without “bumping” or using any power from the leg on the ground. A strong knee with little delay and great muscle recruitment will always be able to lift the person without issue – barring things like obesity or back pain. The following video highlights his lack of confidence in the before section as he tries to push onto the knee. This phase comes after the wobble pad phase where a lot of stability was gained but he was still lacking the confidence. The confidence improves as he feels the stability is greatly improved.
