Document Summary
Stepping up a stair: concentric quads, eccentric hamstrings. Stepping down a stair: eccentric quads, concentric hamstrings. Stand to sit: eccentric quad, concentric hamstrings. Functionally similar to stepping down a stair. Sit to stand: concentric quads, eccentric hamstrings. Closed chain contraction of one hamstring: single leg bridge, single leg squat, single leg chair scoots. Mcl (particularly when knee is flexed) and then acl (often involves medial meniscus as well) Large valgus/varus or axial rotation with foot planted or hyperextension acl or. Straight plane instabilities are not common because usually more than one structure is damaged. If acl is gone, pull tibia anterior. To know if meniscus is involved, pull tibia anterior and medial. With any ligament repair, knowledge of the forces that exist within the joint as a result of activity or the therapeutic exercise is critical if the repair is to remain undamaged and to be successful. Example: reconstructed acl- protect from anterior shear forces.
