Abstract: Objective To observe the effect of comprehensive rehabilitation on the recovery of knee joint function in old patients severe burned in lower extremity. Methods 49 patients severe burned in lower extremity were randomly divided into observation group (n=25) and control group (n=24). The control group accepted routine rehabilitation, while the observation group accepted comprehensive rehabilitation. They were assessed with the range of motion (ROM) of knee flexion/extension, 45 m-walking, stair activity, Functional Independence Measure (FIM) and muscle strength 3 months after rehabilitation. Results The active and passive ROM of knee, stair activity, FIM score and muscle strength improved more in the observation group than in the control group (P<0.05). Conclusion Comprehensive rehabilitation promotes the recovery of knee function of old patients with severe burn in lower extremity.
