National Physical Therapy Examination (NPTE) Practice Exam

Which muscle is the most important to strengthen for a patient using a lift pressure relief strategy in a wheelchair?

1. Extensor carpi radialis longus

2. Deltoids

3. Biceps

4. Triceps

The correct answer is: Triceps

Strengthening the triceps is crucial for a patient utilizing a lift pressure relief strategy in a wheelchair. The triceps are essential for elbow extension, which is a fundamental movement when lifting oneself off the wheelchair surface to relieve pressure. This action helps redistribute body weight and reduce the risk of pressure sores. In this context, the triceps provide the necessary force to push the upper body away from the chair, allowing for effective relief of pressure on the ischial tuberosities and other bony prominences. While the deltoids, biceps, and extensor carpi radialis longus play roles in upper extremity function and mobility, they do not directly facilitate the critical lifting motion as effectively as the triceps do. Therefore, an emphasis on strengthening the triceps will enhance the patient's ability to perform lift pressure relief safely and effectively.
