Refers to a neuropathic pain along sciatica nerve, be due to inflammation or mechanical compression.
Sciatic Nerve Basic Anatomy
Sciatic nerve is formed from L4 to S3 nerve root. The symptoms may originated from lesion of one or more than one nerve roots. Symptoms of sciatica may arise from any irritation at the nerve root, sacral plexus, nerve trunk, or its peripheral nerve branches.
- Stretching or dull pain along the outer side of buttock and leg, or even down to ankle region
- Numbness, pins and needles, or heat and cold feeling
- Leg muscles weakness, or muscle wasting
- diminished reflex response
Sciatica Main Sources
- Protruded Inter-vertebral Disc
- Spinal stenosis
- Inter-vertebral joint degeneration
- Ligament Hypertrophy (eg. Ligamentum Flava)
- Spinal displacement (eg. Spondylolisthesis)
- Piriformis syndrome
- Sacroiliac joint dysfunction
Protruded Inter-vertebral Disc
This is a medical condition affecting spine in which the outer part of the disc protrudes or herniates into the spinal canal, causing inflammation or compressing on nerve. If the disc compresses the cauda equina, it will result in cauda equina syndrome which is a emergency conditions and needs hospitalisation treatment.
Spinal stenosis is a conditions that occurs when the narrow spinal canal being compressed for its nerve root and spinal cord, resulting in several neurological symptoms. Sources of compression include facet joint degeneration, ligament thickening (Ligamentum Flava)
How Traditional Chinese and Physiotherapy Help?
- Manual Therapy
Release muscle tightness, correct joint alignment and improve range of motion.
- Exercise Therapy
Core muscle training, in order to improve Lumbo-pelvic stability.
1)The systemic review found acupuncture was one of the treatment modalities gained statistically significant improvement in overall recovery in sciatica patients, and they suggest spinal manipulation, acupuncture may be considered in treating sciatica.
