Which symptom indicates the need for lumbar traction?

The presence of symptoms distal to the knee is a significant indicator for the need for lumbar traction. This symptom typically suggests nerve root involvement or radicular pain, which occurs when a nerve in the lower back is compressed or irritated, leading to pain or other sensations radiating down the leg.

In cases where patients report such symptoms, lumbar traction can be a beneficial treatment. This technique helps to decompress the intervertebral discs and spaces, potentially alleviating the pressure on the nerve roots and reducing pain. By creating a separation between vertebrae, lumbar traction promotes disc hydration and can improve spinal alignment, addressing the underlying issues causing the distal symptoms.

In contrast, the other options pertain to conditions that are not specifically indicative of lumbar traction. Neck pain and shoulder tension are typically associated with cervical issues, while minor headaches, unless indicating specific cervical spine problems, would not generally warrant lumbar traction as a first-line treatment.
