National Physical Therapy Examination (NPTE) Practice Exam

What is a common sign of rheumatoid arthritis that could affect treatment approaches?

1. Acute pain in isolated areas

2. Increased muscle spasms

3. Joint instability and fragility

4. Normal range of motion

The correct answer is: Joint instability and fragility

Joint instability and fragility are characteristic features of rheumatoid arthritis, highlighting the progressive and systemic nature of the condition. In rheumatoid arthritis, the immune system attacks the synovium, which lines the joints, resulting in inflammation and deterioration of the joint structures over time. This can lead to weakening of the tendons and ligaments surrounding the joints, causing both instability and an increased risk of injury. This instability significantly influences treatment approaches. For instance, physical therapy may focus not only on reducing inflammation and managing pain but also on strengthening the surrounding musculature to support the affected joints. Additionally, surgical interventions may be considered to correct or stabilize severely affected joints. In contrast, options such as acute pain in isolated areas and increased muscle spasms do not capture the chronic and systemic impact of rheumatoid arthritis. Likewise, maintaining a normal range of motion typically contradicts the common presentations seen in this condition, where joint stiffness and deformity can lead to significant functional limitations. Thus, understanding the implications of joint instability and fragility is crucial in tailoring effective treatment strategies for individuals with rheumatoid arthritis.
