Kinesiology of Lower extremity PT 2

Question 1

What do the medial muscles of the hips do? What muscles are included?

Answer 1

Its function is to internally rotate and adduct the hips. The muscles included in adduction are the adductor group: Adductor brevis, Adductor longus and Adductor magnus.
The most important internal rotators include adductor longus and brevis, gluteus medius and minimus, pectineus, and TfL.

Question 2

What is the function of the anterior knee muscles? What are the muscles included? What do the muscles form?

Answer 2

The function of the anterior knee muscles is to extend the knees. Its muscles include the quadriceps femoris, it contains 4 muscles, 3 of which is originate on the proximal femur(Vastus intermedius, vastus, medialis and vastus lateralis) The last muscle, rectus femoris is located on ASIS. These 4 muscles combine distally to form the patellar tendon which houses the patella bone.

Question 3

Should the knees never go past the toes during lunges or squats?

Answer 3

No, it is a myth. In truth, the likely cause of injury during these movements are forward movement of the hips. Researchers confirm that moving the knee past the toes increases knee stress by 28% but restricting knee movement past the toes increases hip stress by 1000%. To counter this issue, before doing the movement, the individual should ensure that the hips are pushed backwards before lowering.
