The infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa. As one of the four muscles of the rotator cuff, the main function of the infraspinatus is to externally rotate the humerus and stabilize the shoulder joint.
Here it is: carpal tunnel syndrome (CTS) in a nutshell!
WHAT: CTS is caused by an injury to the median nerve (MN) as it travels through the wrist.
WHERE: The eight small carpal bones and a ligament form a tunnel in which tendons and nerves pass through to reach the hand.
HOW: The MN gets pinched/irritated from repetitive stress.
WHY: The tunnel is tight as it includes the MN and nine rapidly moving muscle tendons!
PROGRESS: CTS usually starts slow and often progresses over weeks, months, even years.
SYMPTOMS: Pain, numbness, tingling, and/or weakness of the hand, sparing the little finger.
PROGNOSIS: CTS is easier to treat shortly after it starts, and waiting too long to seek care may lead to worse outcomes.
RISK FACTORS: 1) family history (genetics); 2) women are more likely to suffer from CTS than men; 3) age over 50; 4) manual jobs; 5) pregnancy; 6) conditions like diabetes, hypothyroid, rheumatoid arthritis (RA), osteoarthritis, autoimmune diseases (includes RA, certain types of thyroid disease), gout, kidney disease (especially dialysis patients), Down syndrome, amyloidosis, acromegaly, tumors on the median nerve; 7) medications (those that affect the immune system such as interleukin-2, possibly corticosteroids), anti-clotting drugs such as warfarin, hormone replacement, BCPs; 8) obesity; 9) smoking; 10) alcohol abuse; and 11) trauma/injuries (fractures, tendonitis).
TREATMENT: Ideally, treatment should begin as soon as possible after symptoms first start, but this RARELY occurs due its slow and gradual onset. Non-surgical care includes anti-inflammatory care (ice, anti-inflammatory nutrients—ginger, turmeric, bioflavonoids; NSAIDs like ibuprofen), wrist splinting (primarily at night), corticosteroid injections, job/ergonomic modifications, exercises (yoga, stretching, strengthening, and aerobic fitness), low level laser therapy, ice, acupuncture, and chiropractic care. Chiropractic care includes MANY of the above PLUS manual therapies applied to the neck, shoulder, arm, wrist, and hand.
Carpal tunnel syndrome (CTS) can be an extremely painful and activity-limiting condition. It affects many people of all ages and genders, though women are affected more often than men. But how do you know if what you are suffering from is truly CTS or if it’s another condition that’s producing the symptoms in your hand or wrist?
Carpal tunnel syndrome occurs when the median nerve is compressed as it passes through the wrist. However, the median nerve travels out of the neck, through the shoulder, elbow, and forearm before it passes through the wrist and into the hand. Pinching of the median nerve ANYWHERE along its course can give rise to the signs and symptoms of CTS including numbness, tingling, and/or pain into the hand and index, third, and thumb-side half of the fourth digits, and sometimes the thumb. If the pinch is significant enough, weakness can also occur. Sometimes the median nerve can become compressed at both the wrist and other body sites as it travels from the spinal cord to your hand, that’s why it’s important for a doctor to check for impingements along the entire course of the nerve.
But compression of the median nerve isn’t the only thing that can produce symptoms in the hand. Here are a couple of the more common conditions that are often confused with CTS:
1) Ulnar neuropathy: This is pinching of the ulnar nerve (at the neck, shoulder, elbow, or wrist) but this gives rise to a similar numbness/tingling BUT into the pinky-side of the fourth and the fifth fingers (not the thumb-side of the hand). The most common pinch location is either at the neck or the inner elbow, the latter of which is called “cubital tunnel syndrome” or CuTS.
2) Tendonitis: There are a total of nine tendons that pass through the carpal tunnel that help us grip or make a fist. Similarly, there are five main tendons on the back side of the hand that allow us to open our hands and spread our fingers. ANY of these tendons can get strained or torn, which results in swelling and pain as well as limited function BUT there is usually NO NUMBNESS/TINGLING!
3) DeQuervain’s disease: This is really a tendonitis of an extensor tendon of the thumb and its synovial sheath that lubricates it resulting in a “tenosynovitis.” This creates pain with thumb movements, especially if you grasp your thumb in the palm of your hand and then bend your wrist sideways towards the pinky-side of the hand.
Chiropractors are well-trained to diagnose and treat patients with CTS. And if you don’t have CTS but another condition listed above, they can offer treatment (or a referral, if necessary) to help resolve it so you can return to your normal activities as soon as possible.
This week, we will conclude our three-part series on important facts regarding carpal tunnel syndrome (CTS).
CTS TREATMENT OPTIONS (continued): Aside from the carpal tunnel, there are several places where the median nerve can become compressed as it travels from the neck, down through the shoulder, through tight muscular areas of the upper arm and forearm, and finally through the carpal tunnel at the wrist. In order to achieve good, long-lasting results, treatment must focus on relieving compression at any point along the course of the nerve. This is why chiropractic works SO WELL as it addresses ALL of these areas using manual adjustments, muscle release techniques, and even physical therapy modalities.
CTS PREVENTION: Because there are multiple causes of CTS, prevention must be tailored to each person. For example, if the patient has diabetes mellitus, maintaining a proper blood sugar level is very important because the blood becomes thicker as the sugar levels increase and it simply cannot pass through our small blood vessels (capillaries), especially those located in the feet and hands. This can eventually lead to the need for amputation due to poor circulation and contribute to the numbness associated with diabetic neuropathy.
Similarly, low thyroid function results in a type of swelling called myxedema that can cause or worsen CTS, and keeping the thyroid hormone balanced in the bloodstream is very important. Managing other conditions that create inflammation or swelling, such as rheumatoid and other types of arthritis, will also help prevent CTS from developing or worsening.
Carpal tunnel syndrome can also occur during pregnancy due to the hormonal shifts similar for those taking birth control pills. The PRICE treatment options presented last month can be very helpful for the pregnant mother and represent important non-medication self-care approaches.
Certain occupations that require fast, repetitive work and/or firm gripping can result in carpal tunnel syndrome because of the friction that results in swelling that occurs when the muscle tendons inside the carpal tunnel rub excessively fast together (kind of like starting a fire with two sticks). Modifying the work task until the swelling is controlled is VERY important, as discussed last month.
Other preventative measures include exercises that keep the muscles and tendons in the forearm and inside the carpal tunnel stretched so that the tendons easily slide inside their respective muscle tendon sheaths. This is accomplished by placing the palm side of the hand (elbow straight) on a wall with the fingers pointing downwards while reaching across with the opposite hand and pulling the thumb back until you feel a good firm stretch. Hold this position for 5-10 seconds or until the forearm muscles feel like they are relaxing. Repeat this multiple times a day.

Healthcare providers tend to agree that in non-emergency situations, patients with conditions like Carpal Tunnel Syndrome (CTS) should try non-surgical treatments before consulting with a surgeon. The “PRICE” concept, that is Protect, Rest, Ice, Compress, & Elevate can be applied to most injuries, including CTS, especially in the acute/inflammatory stage. However, many of these principles also apply in the chronic stage (more than three months) of CTS.
PROTECT: For the CTS patient, many doctors commonly prescribe a wrist cock-up splint to be worn overnight, which may surprise some of you! During the day, depending on the type of work you do, a wrist splint can actually get in the way and result in increased symptoms, and at times, cause bruising at both ends of the splint (mid-forearm & mid-hand). The primary reason to use the splint at night is that one cannot control the position of their wrist during sleep, and it can often wind up bent. This increases the pressure inside the carpal tunnel up to six to eight times more than normal, potentially causing enough pain and tingling to disturb sleep. The splint guarantees a neutral wrist position, which significantly improves sleep quality and allows healing to occur.
REST: The use of a splint allows the swollen median nerve to heal. However, in order to allow the wrist to rest so inflammation can subside and the condition can fully heal, patients often need to modify their daily activities, at least for a short time. This may require job restrictions, especially if the occupation involves a fast repetitive motion type of tasks and/or forceful gripping.
ICE: The use of an “ice cup”—or an ice cube held with a washcloth to protect the fingertips from getting cold—is by far the most effective approach. Rub the ice directly on the skin over the carpal tunnel so that you experience the four stages of cooling: Cold, Burning, Aching, and Numb (C-BAN). This usually takes about four minutes, and it’s important to stop when numbness occurs, as the next stage of cooling is frostbite. This can be repeated multiple times a day and is often as effective as cortisone shots with fewer side effects (and less pain!).
COMPRESS: The wrist cock-up splint can offer some compression, but an elastic carpal tunnel wrist band will not usually interfere with most activities of daily living. Some versions include a thumb loop to keep the wrist band in place, but that may get in the way. A version without the thumb loop also works very well.
EXERCISE: Exercises performed at home and work can significantly help manage the condition. (Note: For injuries like a sprained ankle, E typically stands for ELEVATE, though it’s not practical for the CTS patient.)
Tune in next month for the unique techniques that chiropractic offers to the non-surgical care of CTS as well as the importance of preventative measures and research.

If tingling/numbness primarily affects your thumb, index, third, and ring fingers, it very well could be carpal tunnel syndrome, or CTS. Chances are you’ve probably had this condition for months or even longer but it’s been more of a nuisance than a “major problem” and therefore, you probably haven’t “bothered” having it checked out. Let’s take a look at some “facts” about CTS!
There is a lot to be learnt from this video. Dr. Mike Evans does a great job of explaining why we need to KEEP MOVING during and after an episode of low back pain. Check it out!
