Seated leg extensions

During the treatment, the subject will be positioned at the side of the bed and will alternate between sitting and standing. The compression band will be placed on the upper third of the thigh, and the subject will perform knee flexion and extension exercises. To engage the muscles fully, the subject will exhale for three seconds during a centripetal contraction and inhale for three seconds during a centrifugal contraction. At the peak of the muscle contraction, the subject will hold the position for one second

In the first week, there were four groups with 15 participants in each group. In the second week, there were five groups with 20 sessions per group. The third week consisted of Group 6 with 25 sessions per group. Additionally, Group 4 had six participants and underwent 25 sessions per group

Standing Leg Curl

In this exercise, the subject should stand with their thighs still and complete a retroflexion of the knee. They should exhale for 3 s during knee flexion and inhale for 3 s during knee extension. Additionally, they should hold the position for 1 s at the peak of muscle contraction
