![]() Interesting fact: In 1938, Kellgren actually found that injecting saline in this muscle produced the same symptoms. You are looking for a region that reproduces your symptoms at the hand, wrist and/or forearm. Tenderness at the infraspinatus alone is not necessarily enough. Using a ball or thera-cane over the infraspinatus could also get the job done. My recommendation would be a medical provider that is familiar with myofascial pain. You can offer the job to a friend or family member that has been waiting for years to make you cry like a baby. Press your finger into the infraspinatus muscle looking for tenderness. How can I tell if the Infraspinatus muscle is at fault? ![]() However, as we mentioned earlier, we would need a nerve conduction study and/or EMG study to confidently make a CTS diagnosis. Muscle atrophy (wasting) at the palm, hand weakness and clumsiness would having me leaning more toward a CTS diagnosis. So now we need to ask ourselves, is this a true carpal tunnel or are these sensations generated from the infraspinatus muscle? If we compare the location of symptoms found with infraspinatus trigger points and carpal tunnel it is hard to say. Glad you asked! As we discussed earlier, trigger points in the infraspinatus muscle can reproduce pain, numbness and/or tingling in the same region as carpal tunnel. ![]() So if it is not carpal tunnel syndrome, what else could it be? During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle ().īased on these findings, your suspect carpal tunnel syndrome will be classified as either: Also called a myogram, an electromyography ( EMG) measures muscle response or electrical activity in response to a nerve's stimulation of the muscle.During the test, the nerve is stimulated, usually with surface electrode patches attached to the skin (). NCS can determine nerve damage and destruction. ![]() A nerve conduction study (NCS), also called a nerve conduction velocity (NCV) test-is a measurement of the speed of conduction of an electrical impulse through a nerve.To confidently diagnose carpal tunnel syndrome your physician needs to find: How Do you accurately diagnose carpal tunnel syndrome? Weakness and atrophy at the base of the thumb are commonly seen over time.Numbness, tingling and/or pain may also spread into the arm or shoulder. Sensory deficits in the Median innervated region of the hand ( thumb, the index finger, the middle finger and the lateral half of the ring finger).Swelling, weakness or clumsiness of the hand.Painful tingling in the hand during the night. ![]() The symptoms of carpal tunnel syndrome often appear as: In our last post we discussed the role trigger points can play in pain, numbness and/or tingling in other regions of the body.Ĭarpal tunnel syndrome is the entrapment of the Median nerve at the wrist. Something I commonly see with a suspicious carpal tunnel diagnosis is the reproduction of “carpal tunnel” like symptoms with touching or pressing on the infraspinatus muscle (one of your four rotator cuff muscles). The goal of this post is to help you determine the validity of that diagnosis. Today I want to discuss your supposed carpal tunnel diagnosis. I can’t wait to start offering some more visual content that helps you better understand how to care for yourself! Over the past few days I have been getting more proactive with videos. Always fun seeing how much joy they get out of the little things in life that I often take for granted. We even got to spend time with our beautiful little nephews. To their surprise they were somewhat unexpectedly tricked into helping us move out of our apartment! We also made some time for ice cream and hanging out by the harbor in downtown Baltimore. My wife, Jeanna, and I got to visit with her family for Father’s Day. The last few days have been a lot of fun. ![]()
