Which treatment modality is indicated for patients with nerve root impingement and/or radiculopathy?

1. Ultrasound therapy

2. Cold therapy

3. Traction

4. E-stim

The correct answer is: Traction

Traction is indicated for patients with nerve root impingement and/or radiculopathy because it helps to relieve pressure on the spinal nerves. When a nerve root is compressed, it can lead to pain, weakness, numbness, and other symptoms associated with radiculopathy. Traction works by gently stretching the spine, which increases the space between vertebrae, potentially reducing the compression on the nerves. This can help alleviate pain and promote better circulation to the affected area, leading to improved function and comfort for the patient. The other treatment modalities listed have different primary uses and effects. Ultrasound therapy is mainly employed for tissue healing and reducing inflammation, which may not directly address nerve root compression. Cold therapy is typically used for pain relief and swelling reduction, but it does not create the necessary spinal decompression that can alleviate nerve impingement. Electrical stimulation (E-stim) can be effective for pain relief and muscle activation but is not specifically designed to address the mechanical compression of nerve roots.
