In the UK, up to 60% of the population will expect to have low back pain at some point in their life. Around 20% of the population will consult with their GP to seek a solution for their lower back pain. Low back pain is defined as pain in the region between the bottom of the ribs and top of the legs.
Sciatica describes symptoms of pain, tingling, numbness, and occasionally weakness arising from impingement of nerve roots as they emerge from the spinal canal. This is normally felt from the buttocks and radiating to behind the knee. It is thought that between 5-10% of patients with non-specific low back pain also have sciatica.
