Supine knee extension over towel roll to strengthen quadriceps through limited range isometric contraction.
Lie down on your back and keep a towel roll under your knees to keep the knees bend. Press the knees on the towel roll so that the heels are lifted off the ground. Maintain the position and feel the contraction before lowering heel to ground.Repeat the sets.
Nothing here is a prescription. Your physiotherapist decides which of these are yours, and when.
