The distribution usually follows the nerve root, and the paresthesia may be provoked by neck movement. Electromyography and imaging of the cervical spine can help to differentiate cervical radiculopathy from carpal tunnel syndrome if the diagnosis is unclear. Carpal tunnel syndrome is sometimes applied as a label to anyone with pain, numbness, swelling, or burning in the radial side of the hands or wrists. When pain is the primary symptom, carpal tunnel syndrome is unlikely to be the source of the symptoms.When the symptoms and signs point to atrophy and muscle weakness more than numbness, consider neurodegenerative disorders such as Amyotrophic Lateral Sclerosis or Charcot-Marie Tooth. Prevention
There is little or no data to support the concept that activity adjustment prevents carpal tunnel syndrome. The evidence for wrist rest is debated. There is also little research supporting that ergonomics is related to carpal tunnel syndrome. Due to risk factors for hand and wrist dysfunction being multifactorial and very complex it is difficult to assess the true physical factors of carpal tunnel syndrome.Biological factors such as genetic predisposition and anthropometric features are more strongly associated with idiopathic carpal tunnel syndrome than occupational/environmental factors such as hand use. Treatment
CTS related to another pathophysiology is addressed by treating that pathology. For instance, disease-modifying medications for rheumatoid arthritis or surgery for traumatic acute carpal tunnel syndrome.Generally accepted treatments include: physiotherapy, steroids either orally or injected locally, splinting, and surgical release of the transverse carpal ligament. Limited evidence suggests that gabapentin is no more effective than placebo for CTS treatment.
Manual therapy included the incorporation of specified neurodynamic techniques, functional massage, and carpal bone mobilizations. Another group only received treatment through electrophysical modalities. The duration of the study was over the course of 20 physical therapy sessions for both groups. Results of this study showed that the group being treated through manual techniques and mobilizations yielded a 290% reduction in overall pain when compared to reports of pain prior to conducting the study. Total function improved by 47%. Conversely, the group being treated with electrophysical modalities reported a 47% reduction in overall pain with a 9% increase in function. Alternative medicine
A 2018 Cochrane review on acupuncture and related interventions for the treatment of carpal tunnel syndrome concluded that, "Acupuncture and laser acupuncture may have little or no effect in the short term on symptoms of carpal tunnel syndrome (CTS) in comparison with placebo or sham acupuncture." It was also noted that all studies had an unclear or high overall risk of bias and that all evidence was of low or very low quality. Prognosis
Most people relieved of their carpal tunnel symptoms with conservative or surgical management find minimal residual or "nerve damage". Long-term chronic carpal tunnel syndrome (typically seen in the elderly) can result in permanent "nerve damage", i.e. irreversible numbness, muscle wasting, and weakness.
