Carpal Tunnel Syndrome
Carpal tunnel syndrome (CTS) is a debilitating disorder caused by irritation or pressure to the median nerve. The median nerve originates in the neck, runs through the shoulder, arm and forearm into the wrist and hand.
Can Upper Cervical Chiropractic Help Carpal Tunnel Syndrome?
The most common misperception about Upper Cervical care is that it only helps back and neck pain. Although our doctors can certainly help those who come to us seeking relief from back and neck pain, these patients represent a small percentage of those helped by Upper Cervical chiropractors. Patients suffering from a variety of conditions, including carpal tunnel, have had their health restored through Upper Cervical chiropractic. Upper Cervical chiropractors recognize that the body is a self-healing organism controlled and coordinated by the central nervous system, which is protected by the skull and spine.
Upper Cervical Care – A Simple Concept
Upper Cervical care is based on the universal law of cause and effect. For every effect or symptom, physical or mental, there must be a cause. Upper Cervical chiropractors focus on locating and removing interference to the nervous system that can be the cause of the health condition. Removing this interference allows the body to heal itself naturally without drugs or surgery. An Upper Cervical correction is very controlled; there is no pulling, tugging, or jerking of the head. This precise yet gentle touch allows the head, neck, and spine to return to the proper position, thus removing the interference and restoring balance to the body.
Carpal Tunnel Syndrome
Carpal Tunnel Syndrome (CTS) is a debilitating disorder caused by irritation or pressure to the median nerve which originates in the neck, runs through the shoulder, arm and forearm, and into the wrist and hand. It is one of the major nerves in the hand that provides sensation and movement for the thumb, index and middle fingers. CTS is often described as an aching pain with burning, tingling, and numbness in the wrist or hand and, occasionally, in the forearm. In some cases, muscle weakness, swelling and loss of temperature sensation may be present. Sufferers of carpal tunnel may begin to drop objects or have difficulty lifting small items or turning doorknobs.
Some think there is a higher incidence of CTS among those who do work which requires them to use their hands, wrists, or arms in a repetitive manner, but renowned hand surgeon, Dr. Charles Eaton, says there is no scientific evidence that shows such activities actually cause carpal tunnel syndrome.
The standard medical treatments for CTS include braces, splints, over-the-counter or prescription non-steroidal anti-inflammatory drugs (NSAIDs), vitamin B6, cortisone injections, or surgery. Unfortunately, drugs have potential side effects, and surgery is not always successful.
Three separate studies published in the Journal of Hand Surgery followed the failure rate of some of the common treatments for CTS. One study revealed that wrist splints and NSAIDs had an 82.6% failure rate while another showed steroid injections had a 72.6% failure rate. The third study showed an average failure rate of 57% in patients that underwent carpal tunnel release surgery.
These failure rates support the idea that the actual cause of CTS in the majority of patients might be nerve irritation at a site away from the wrist, as is the case with Double Crush Syndrome.
Double Crush Syndrome & Carpal Tunnel
Stress to the median nerve commonly begins in the neck (Diagram #1 – cervical spine), where the median nerve begins. The nerve is then aggravated by added pressure or irritation anywhere from the neck to the wrist (Diagram #2), which can then cause symptoms in the hand and fingers. This is called “Double Crush syndrome” and is widely referenced in the scientific and medical research journals as a consistent finding in patients with carpal tunnel syndrome. Pressure or irritation to the nerve roots as they exit the neck makes the median nerve more vulnerable to injury at the wrist.
A growing number of studies suggest that the Double Crush phenomenon is one of the most common causes of CTS. The prestigious medical journal, The Lancet, found that nearly 7 of every 10 CTS patients had nerve irritation in the neck. Another study found that 89% of carpal tunnel sufferers also had arthritis in the neck. Both studies suggest the vast majority of CTS patients actually have Double Crush phenomena.
This would explain the high failure rate of common medical treatments for carpal tunnel syndrome. Treatments directed solely at the wrist neglect possible nerve irritation or compression in the neck, which renders the lower nerves in the wrist more susceptible to injury. In this case, it is essential to first correct the cervical problem to allow the wrist condition to fully heal. A similar phenomenon can also occur with Thoracic Outlet Syndrome (TOS) and cervical radiculopathy (tingling, pain down the arms).
CTS and the Cervical Spine
Problems in the neck or cervical spine can be as simple as poor posture and muscle tension, or as serious as disc bulges, arthritis, or spinal misalignments, also referred to as subluxations.
A proper evaluation for CTS should include an exam of the entire length of the median nerve, starting at the neck and working down to the hands, wrists and fingers. Since the neck is the most common site for Double Crush to occur, a consultation with an Upper Cervical chiropractor would be in the best interests of any CTS sufferer, especially if they have been recommended for carpal tunnel surgery.
The purpose of Upper Cervical Chiropractic is to correct misalignments in the neck that produce irritation to the nerve roots that extends to the wrist, hands, and fingers. Clinical findings document that this can prevent the need for surgery.
