Carpal Tunnel Syndrome

Carpal Tunnel Syndrome (CTS) is a neuropathic condition resulting from compression of the median nerve at the level of the wrist. This disorder typically arises due to increased pressure within the carpal tunnel, a narrow passageway in the wrist, which compresses the median nerve. CTS is the most common entrapment neuropathy of the upper extremity and is generally characterized by pain, numbness, tingling, and weakness.

Symptoms of the Syndrome

The most common symptoms of CTS include numbness, burning, pain, and weakness in the thumb, index finger, middle finger, and the radial half of the ring finger. Patients often report that their symptoms worsen during nighttime hours. CTS may also manifest as difficulty gripping objects, holding items, or moving the fingers. During physical examination, these symptoms are more pronounced in patients with positive Tinel and Phalen tests.

Risk Factors

CTS occurs more frequently in individuals with certain risk factors, including genetic predisposition, repetitive hand and wrist movements, overuse, obesity, diabetes mellitus, rheumatoid arthritis, thyroid disorders, smoking, and advanced age. Women, particularly those between 40 and 60 years of age, are at higher risk than men.

Diagnostic Methods

The diagnosis of CTS is established based on clinical symptoms, physical examination findings, and electrophysiological tests (EMG). The Tinel and Phalen tests are provocative tests that are interpreted as positive or negative according to the patient’s symptoms. EMG reveals slowed conduction velocity of the median nerve and increased distal motor latency. The severity of CTS is classified according to EMG findings as mild, moderate, or severe.

Treatment Approaches

Treatment options for CTS include conservative measures and surgical intervention. Conservative treatment may involve splinting, physical therapy, steroid injections, and exercises. These options are generally sufficient for mild to moderate cases. However, in advanced cases, surgical intervention may be required to reduce pressure on the median nerve.

• Splinting: Splints that maintain the wrist in a neutral position are frequently used in CTS treatment to reduce pressure on the nerve. Nighttime use of splints can help alleviate symptoms.
• Nerve and Tendon Gliding Exercises: These exercises aim to facilitate free movement of the nerve. However, studies have shown that they are not equally effective in all patients.
• Vitamin B Supplements and Other Treatments: Vitamin B therapy may be recommended for mild cases. Additionally, splinting and electrotherapy are among the treatment options.
• Electroneuromyographic (EMG) Findings: EMG plays a critical role in confirming the diagnosis of CTS. This test assesses the conduction velocity of the median nerve and its motor responses to determine disease severity. In CTS patients, EMG typically shows reduced conduction velocity and increased distal motor latency of the median nerve.

Effect of Physical Exercises

Various findings suggest that physical exercises, particularly nerve and tendon gliding exercises, can contribute to the treatment of CTS. However, it has also been observed that these exercises do not produce the same level of benefit in all patients. On the other hand, some studies indicate that exercises may have positive effects on pain management and functional recovery.

Potential Future Perspectives

CTS is a condition that can be effectively managed with early diagnosis and treatment. However, some uncertainties remain regarding the effectiveness of various treatment methods. Research has demonstrated the efficacy of splinting, exercises, and surgical intervention, but emphasizes the need for individualized treatment plans tailored to each patient. Furthermore, future studies involving larger patient populations will enable further optimization of treatment protocols.
