Eye Training

the knee needs to bend from thigh swing. Even preop emg won't catch this as it is buried in the co-contraction emg soup. An ethanol RF nerve perineural injection is usually enough, but occasionally the pelvic attachment needs to be 'recessed' (detached from pelvis and buried in with the rest of the proximal quadriceps. Methods vary. Another wrong concept to beware of: “Out of phase”. What is it exactly? When geeks who only read charts see that a muscle has fired here on the x axis, when it should have been there - it is out of phase. That's a timing expression. It is happening WHEN. The question should be WHAT is firing that muscle & why. So a person with supple calf and very normal ankle range including dorsiflexion keeps going on toe and not for any possible compensatory reason (other foot in plantar flexion?). Look at the slow motion video frame by frame and repeatedly the OK foot posture suddenly plantar flexes just as the swinging knee extension gets to a certain point and pow the foot suddenly points down. That isn't a time issue. It is the overly reflexive medial gastrocnemius (the high speed part of the calf complex) getting tugged on over the medial femoral condyle. Recess that proximal attachment off the condyle to the adductor longus long head attachment at the neutral point of the knee axis and that reaction goes away. It does not lengthen. A lengthening would damage power. It wasn't short. This isn't a common diagnosis, but it is extremely illustrative of this phenomenon where ever it is, not just rectus femoris. I It is a major part of arm posturing during walking reacting to arm swing. Enough. Go eat something. We're done here.
