What is carpal tunnel?
A common condition affecting over eight million people in the United States alone, carpal tunnel syndrome (CTS) occurs when the passageway formed by the wrist’s carpal bones compresses the median nerve. CTS most commonly causes pain, numbness, tingling, burning, and “shock-like” sensations in the thumb, index, middle, and ring fingers. The neuropathic sensations produced by carpal tunnel syndrome may also radiate up the arm to the forearm and shoulder.
For most CTS sufferers, physical therapy provides the best and most effective treatment option. PT wrist strengthening exercises designed to reduce pressure on the median nerve can, in a majority of cases, restore normal sensation in the hand, wrist, and arm — with surgery being the preferred option only for acute cases of CTS.
Such severe cases typically result from extreme and/or long-term median nerve compression, and can cause atrophy (or wasting) of the muscles in the hand and wrist, negatively affecting grip strength, pinch strength, and dexterity (think: threading a needle). Less common causes include traumatic injuries to the wrist.
