The lumbar nerve roots surface finish the spine and at this time they are vulnerable to impingement from a disc prolapse, triggering inflammation and/or compression of the nerve and the symptoms of sciatica. Sciatic leg pain is not common, affecting 3 to 5% of adults and both sexes equally. Males may get it in their 40s and women in their 50s, with pain symptoms lasting over six weeks in up to a quarter of cases. Physiotherapists are often asked to supervise the management of sciatica.

Once the intervertebral disc materials prolapses it causes personal injury by two mechanisms: immediate mechanical compression of the nerve and chemical irritability. The disc material ought not to be outside the disc and its toxic compounds help swelling both of the nerve and its bordering structures, resulting in congestion of the circulation and of the nerve’s normal message conduction. Even though the prolapse is in charge of the sciatica it has not been proven that the bigger the prolapse the more severe the person’s pain.
The great forces which we impose on the low back mean the rear intervertebral discs suffer strength changes and prolapses. A large number of activities involve a significant level of leverage, such as flexing over, doing movements in an straight position and lifting with the arms away from the body. This greatly magnifies the forces on the discs and credited to their fluid technicians they suffer 3-5 times the loads on the skeleton. This can cause the disc walls to degenerate, giving weak areas and predisposing to prolapse at some time.
The onset of lumbosacral radiculopathy is often sudden with mid back pain and any back pain may disappear at the start of the leg pain. Worsening factors are coughing, coughing and sitting with lying down or ranking up common easing factors. Sciatic pain typically occurs in the buttock, back again or side of the leg and calf and into the foot. In the event the disc prolapse is higher up (prolapses at disc levels L1 to L3 are 5% of the total) the pain may take the entry of the thigh no further than the sexy. A patient may have an isolated area of pain and still have a prolapse.
The physiotherapist will take the person’s history with particular attention to “red flags” which can be indicators of a serious medical reason for the back pain and the patient will not be appropriate for physio. Excess weight loss, fever, night sweating, age (under 20 or higher 55), problems with bladder and bowel control, serious past medical record and night pain will be noted. Any concern means referral to a doctor for investigation. The physio will note any postural abnormalities and the type, position and activity response of the pain symptoms.
A patient with lumbar radiculopathy may demonstrate abnormal posture, sometimes curved forward and unable to bend backwards, with an one-sided trunk shift. Physiotherapists check the ability to accomplish spinal movements, any style of limitation or inclination for the pain to centralise on repeated actions. Physios will test the reflexes, sensibility and muscle power to perform the neurological examination. This and those straight leg raising test permit the physio to check which of the spinal nerves may very well be the culprit.
Discogenic pain may change with repeated moves, spreading more towards the leg or in towards the back, the second option being called centralisation. Physiotherapists use this phenomenon to diagnose and treat disk related back pain and examine the joints of the lower limb as thigh and knee pain can be referred from an osteoarthritic hip joint. A full history and examination both eliminates patients who require medical recommendation for investigation and allow the physio to create a treatment strategy.
Therapy sciatica treatments include many therapies: manipulation, mobilisation strategy, lumbar stability, myo-fascial release, McKenzie method (especially useful in disc prolapse), stabilizing exercise, massage and smooth tissue techniques, pain criminals, education of the individual, advice on the best position to relieve extreme sciatica pain and rest. Sciatica settles as the pressure and inflammation ease but physiotherapists would recommend a continuing exercise programme to maintain back fitness over the long term.
