Contractures are a serious complication for individuals confined to a bed for extended periods. A contracture is a fixed tightening of muscles, tendons, or soft tissues that severely limits a joint’s range of motion. This shortening occurs because prolonged immobility causes muscles to adapt to a shortened position. Prevention is the best approach, as restoring movement once a contracture develops is often difficult and painful. Caregivers can maintain flexibility, ease daily care, and improve the patient’s quality of life by implementing consistent strategies.
Maintaining Joint Alignment Through Proper Positioning
Proper positioning is foundational for preventing contractures, focusing on maintaining a neutral, slightly extended posture during rest. The goal is to avoid prolonged static positions that encourage muscle shortening, particularly the tendency for joints to remain flexed. Pillows, wedges, and towel rolls are effective tools used to support the body in healthy alignment.
When the patient is lying on their back, a small roll under the ankles prevents the feet from pointing downward, which helps prevent foot drop. Placing a pillow between the knees when the patient is on their side prevents excessive hip and knee flexion. Caregivers must ensure joints are not bent out of alignment, as a comfortable, flexed position maintained too long can lead to contracture. Frequent repositioning, which also prevents pressure ulcers, is beneficial for joint health.
Implementing Range of Motion Exercises
Range of Motion (ROM) exercises are the dynamic component of contracture prevention, actively working joints through their available movement to maintain flexibility. These exercises should be performed gently and systematically, ideally multiple times throughout the day. Movement can be Active ROM (patient moves the joint) or Passive ROM (caregiver moves the joint).
During Passive ROM, the caregiver must move the joint slowly and smoothly, supporting the area near the joint while manipulating the limb. The joint should be moved until a gentle resistance is felt, but never past the point of pain. Gentle rotations can be performed at the shoulder, wrist, and ankle to ensure movement across all planes.
Utilizing Supportive Devices and Splinting
Supportive devices and splinting maintain the stretch achieved during ROM exercises and keep at-risk joints in a functional, neutral position during rest. These devices provide a prolonged, low-load stretch that prevents the shortening of soft tissues. Examples include resting hand orthoses, which keep the wrist and fingers extended, and ankle-foot orthoses (AFOs), which hold the foot at a 90-degree angle.
Orthoses are beneficial to wear overnight, as they counteract the tendency for muscles to tighten during sleep. Proper fit is important, and caregivers must monitor the skin beneath the device for signs of pressure or breakdown. Dynamic splints, which use tension to apply a constant, gradual stretch, may be employed to increase the range of movement. Any specialized device should be used in consultation with a physical or occupational therapist to ensure it is appropriate for the individual’s needs.
Developing a Consistent Care Schedule
Integrating preventive measures into a reliable daily routine is fundamental, as consistency is the most effective approach to contracture management. A fixed schedule ensures that no preventative step is overlooked and that the benefits of each intervention are maintained throughout the 24-hour cycle.
Repositioning frequency varies; while some patients need turning every two hours, others may require more or less frequent movement based on risk factors. Range of motion exercises should be performed at least once daily, though twice a day is often recommended to counteract muscle adaptation. Caregivers can link these tasks to established events, such as checking positioning during medication times or performing ROM exercises before a meal. Documentation of the schedule and the patient’s response is a useful tool for coordinating care among all team members.
