For anyone who has had knee rehabilitation treatment, you will know how hard is can be to get the knee working. At Therapyroom1 we have had patients who struggled with strengthening and conditioning of their quadriceps muscles to take an increased load without being weight bearing (standing up on it) and we came up with this one that they could do at home. If you like it you can do it too. This exercise is particularly good for patients who have suffered from partial or total dislocation of the knee and post knee replacement surgery.

Again for the medical therapists amongst you; eccentric, concentric and ecconcentric muscle activity occurring in this exercise.

Level: Intermediate Stage

Equipment: None

Exercise Instructions

Lay on your back with your legs out straight.

Slightly bend your injured knee keeping your heel in contact with the bed/floor and your toes up.

Slowly contract your thigh muscles and raise your foot up 2 inches off the floor (see diagram).

Lower your foot to the ground (table/bed).
