For a patient diagnosed with cervical radiculopathy, what is likely the best intervention based on the diagnosis alone?

1. Repeated cervical extension

2. Constant mechanical traction

3. Intermittent mechanical traction

4. Joint mobilization of the cervical spine

The correct answer is: Intermittent mechanical traction

For a patient diagnosed with cervical radiculopathy, intermittent mechanical traction is often considered an effective intervention based on the diagnosis. This approach helps alleviate symptoms associated with nerve root compression by creating negative pressure in the intervertebral disc space and stretching the surrounding structures. Intermittent traction allows for cycles of tension and release, which can help improve blood flow, decrease muscle spasm, and reduce pain while promoting the mobility of the cervical spine. The rationale behind using intermittent mechanical traction is that it targets the specific symptoms of cervical radiculopathy, which often include pain radiating down the arm, sensory changes, and weakness. By alleviating pressure on the affected nerve root, intermittent traction can facilitate symptom relief and potentially improve function. Other choices, such as repeated cervical extension, constant mechanical traction, and joint mobilization, may not target the specific needs of a patient with cervical radiculopathy as effectively. Repeated cervical extension could exacerbate symptoms if extension positions increase nerve root compression. Constant mechanical traction, while potentially useful, does not provide the dynamic benefits that intermittent traction offers. Joint mobilization may be beneficial for restoring mobility, but it may not directly address the radicular symptoms as effectively as traction can. Therefore, intermittent mechanical traction stands out as the most
