Trigger Point Therapy - Sciatica

Posted by Judith Winer on Jan 04, 2016

When we analyse the traffic through our clinics at the end of each quarter, sciatica seems to be always up there in the top ten. There are probably two good reasons for this. The first is that sciatica is one of those conditions where the pain can be extremely severe. The second, is that manual therapy has long since been recognised as being effective for providing relief, even by most medical doctors. In fact, any therapist familiar with trigger point therapy will tell you that they're always upbeat going in to treat sciatica, as the effects of the therapy are in most cases, extremely positive. This is something that has been reaffirmed in a number of studies.

Sciatica is a symptom of an underlying medical condition, such as a lumbar herniated disc, degenerative disc disease, or spinal stenosis. It is not a medical condition in and of itself.

The condition is characterised by pain that radiates along the path of the sciatic nerve. This is the largest nerve in the body, beginning at the lower back, and running through the hips and buttocks down to each leg. In most cases, sciatica affects only one side of the body, but can affect both (bilateral sciatica). 

Where symptoms are felt in both legs, it typically means that the cause of the compression, such as a herniated disc, is big enough to compress nerve roots on both sides of the spine. It is of course possible that two separate conditions have developed on opposite sides of the spine, but this would obviously be a rarity.

In most cases, sciatica develops when the sciatic nerve is compressed by a herniated disk or bone spur. This causes inflammation, pain, and sometimes numbness in the affected side. It's worth noting that it's not unusual to come across sciatica in pregnant women due to an irritation of the sciatic nerve during pregnancy.

What Are the Symptoms of Sciatica?

The pain associated with sciatica can vary in degree. We see many clients who experience infrequent pain whilst others suffer so severely from the pain as to be largely incapacitated.

Sciatica is often characterised by the following symptoms. The client may experience only one or a combination:

• Constant pain in one side of the leg or buttock
• Pain worsens when sitting
• Burning, tingling, or searing pain in the leg
• Weakness, numbness, or difficulty moving the leg or foot
• A sharp pain which might affect the ability to walk or to stand up

Clients often describe how these symptoms worsen when they cough, sneeze, or sit for a long period of time.

Who Is Prone to Sciatica?

The probability of experiencing pain from sciatica peaks in the 50's and then declines. It is rare to see clients under the age of 20 suffering from this condition. Those who suffer from degenerative arthritis of the lumbar spine, lumbar disc diseases, slipped disc, or a trauma or injury to the lumbar spine are the groups who are at a higher risk.

Studies have shown that obesity or even being overweight can increase the risk of sciatica, as the weight will increase stress on the spine. A job that requires you to twist your back, carry heavy objects, or drive a motor vehicle for long periods of time, may also contribute to increasing the risk factor. The other group worth noting are diabetes sufferes who are at increased risk because the way that the body uses blood sugar increases the risk of nerve damage.

In summary, whilst there are those cases of sciatica which require more aggressive intervention to deal with the underlying cause, the preferred and most effective treatment in most cases is manual therapy including trigger point therapy, and prescribed stretching and strengthening exercises.

The trigger points commonly (almost always) associated with sciatica are found in priformis, and gluteus maximus.
