What are the possible causes of sciatica?

Firstly, sciatica can occur following a herniated disc or any irritation at the base of the nerve root. If the irritation or compression is important the symptoms will be more intense and might happen further down the leg.

Sciatica can also be associated with arthritis or other degenerative disorders that irritate the nerve at its root. Usually, lack of mobility and osteophytes (little bone spurs around the edges of the vertebrae) can provide the nerve from gliding freely and compress the nerve and create sciatica symptoms.

Compression can also occur at any level of the sciatic nerve in leg. Commonly, the piriformis muscle located in the buttock is the one causing most troubles, since the nerves passes under the muscle in most people.



Most physiotherapy interventions in sciatica cases focus on symptoms elimination. To achieve this goal, the physiotherapist will assess thoroughly all the joints next to the nerve root, the muscle tension around the nerve territory, as well as the fascias mobility, and  the nerve envelop gliding. The physiotherapist will also assess your every life activities to ensure that movement control is optimal and doesn’t add stress on the nerve. Indeed, postural components are primordial when treating sciatica, since daily living activities can increase nerve tension excessively and counter treatment interventions. Of course, the physiotherapist will assess all these components during the initial assessment and come up with a personalized treatment plan for you specific presentation.
