The exercise described is useful for alleviating sciatica symptoms because it targets the underlying cause of the pain, which can often be related to the piriformis muscle or the lower back (disc-related issues). Here's how it helps:
By positioning the affected leg in a crawling-like position and adjusting the hips, the exercise aims to find a position that puts the piriformis muscle on slack. This helps in reducing tension and inflammation in the muscle, which can alleviate the pressure on the sciatic nerve.
Holding the comfortable position for 90 to 120 seconds allows the muscle to relax fully. Relaxation and deep breathing help to reduce muscle spasms and improve blood flow, which can reduce pain and promote healing.
Slowly returning to a neutral position and taking a short walk helps in maintaining the muscle relaxation achieved during the exercise. Gentle movement encourages circulation and prevents the muscle from tightening up again.
