Document Summary

2-3: difficulty walking/running following, site of pain - usually biceps and usually mt junction but can be anywhere, ischial tuberosity with stretch. Grade 1: slight tightness and tension in the muscle, fair to good strength (how do we grade?, few then 20% of fibers torn, if any, strength 5/4. Grade 2: feel a pop or experience a tearing sensation, unable to extend the knee, significant pain and weakness in the muscle, fewer than 70% of fibers torn, 3/2. Grade 3: as per grade 2, palpable defect or mass, greater than 70% of fibers torn, 1/0. Acute: police- compression for support is important (pad, gentle knee flexion/extension rom as able in pain free rom, maintain dynamic stabilizers- especially quads/glutes. Remodeling: stress ++ through injured tissues, need to work concentrically and eccentrically at varying speeds, nordic/russian hams, allow adequate rest to avoid doms, functional proprioception and strengthening.
