Why are passive range of motion exercises conducted for patients with paralyzed limbs?

Passive range of motion exercises are primarily conducted to prevent contractures in patients with paralyzed limbs. When a limb is not used actively, such as in cases of paralysis, the muscles and joints can become stiff and tight over time. This can lead to the shortening of muscles and tendons, resulting in the development of contractures, which are permanent shortening and tightening that restrict movement.

By performing passive range of motion exercises, caregivers or therapists gently move the patient's limbs through their available ranges of motion. This helps maintain flexibility in the joints and muscles, which can prevent the formation of contractures. While other benefits such as enhancing circulation might also occur, the primary focus of these exercises in the context of paralysis is to preserve joint function and mobility by preventing contractures from occurring. Compassionate handling during these exercises also contributes positively to the patient's comfort and overall care.
