Sciatica is the Latin word for “Pain down the back of the leg” Sciatica is referred pain usually caused by trapping the sciatic nerve in the lower back.
Pain Free Physiotherapists regularly treat sciatica and have terrific results.
The sciatic nerve runs from the lower back down through the buttocks and along the back of each leg. Sciatica is pain along this nerve and is a relatively common form of back pain and is usually caused by pressure on the sciatic nerve from a herniated or bulging disc.
The pain from sciatica can be anything from infrequent and irritating to severe and debilitating. Usually, it affects only one side, the pain radiating through the buttock and down the leg and is often associated with a constant pain on one side of the buttocks, pain in the leg and/or buttock that may be worse when sitting , burning or tingling down the leg, weakness, numbness or difficulty moving the leg or foot or a shooting pain that makes it difficult to stand up.
Typically, sciatica is made worse by bending, lifting, sneezing and coughing.
While sciatica can be extremely painful and uncomfortable, it is rare that permanent nerve damage (tissue damage) results. Most pain is due to inflammation and will improve if the Physiotherapist is treating the right point on the nerve root (the cause of the pain).
Sciatica is a common problem for manual workers, sedentary office workers and is particularly prevalent during pregnancy.
Physiotherapy Treatment main objectives are
- find cause
- restore movement
- eliminate pain
- strengthen weakened muscles
Causes of Sciatica
The sciatic nerve is the main nerve in the leg and the largest in the body. It runs from the base of the spine, along the back of the thigh to the knee, where it divides into branches.
Sciatic pain can be caused by many dysfunctions. Compression of the nerve root by a disc injury or muscle dysfunction is the most common cause. This, however, may not be the true structure causing the injury. In many instances, the actual structure causing the issue is not even located in the painful area. It is important not to fall into the trap of thinking that the painful area is the cause of the issue.
Though the pain may present itself in the lower back, it is likely caused by another structural dysfunction elsewhere in the body. The body works as a series of moving cogs, if a cog earlier in the chain malfunctions then it will affect the clockwork elsewhere along the track.
These structural malfunctions can result from a number of reasons including
- Sometimes, just sitting awkwardly can cause sciatica.
- Piriformis syndrome (tightness of the piriformis muscle in the buttock that compresses the sciatic nerve)
- Spinal misalignments, vertebral dysfunction
- Poor posture – wearing high heels, prolonged sitting, poor mattress
- Poor lifting technique and poor bending habits
- Spinal compressions due to osteoporosis
Diagnosis of Sciatica
Since there are many disorders that can cause sciatica, your physiotherapists’ first task is to determine the exact cause of your sciatic nerve interference.
- Always begins with a thorough history,
- Spinal, orthopaedic and neurological examination.
- Special diagnostic imaging investigations such as X-ray, CT, MRI
- Posture pro scan may also be required to accurately diagnose your sciatica.
Treatment of Sciatica
As sciatica is due to pressure on the sciatic nerve, it stands to reason that treatment involves removing this pressure. Your Physiotherapy treatment aims to achieve this by reducing nerve pressure caused by poorly moving spinal joints as well as easing muscular tension in the lower spine, buttock and leg.
This is achieved by using a combination of the following techniques:
- Spinal mobilisations
- Massage therapy and trigger point therapy
- Stretching tight muscles, joints, tendons and ligaments
- Ultrasound and other electrical stimulation devices
- Advice in relation to how to minimise pressure and irritation of the sciatic nerve
In addition to this, you will be given a series of home stretching exercises and asked to apply ice and heat to help aid your recovery.
