Fig. 1. (A) Ankle pumps. Ankle plantar flexion (left) and ankle dorsiflexion (right). (B) Knee-extension strength training. While supine, the patient tightens quadriceps in an attempt to straighten the knee (hold for 5–10 seconds). (C) Straight leg raise. While supine, the patient tightens the quadriceps, flexes the hip and keeps the knee straight while lifting the extremity off the bed (hold for 5–10 seconds), then lowers it slowly.
