Population Adult patients suffering from severe CTS would be a population of the interest. Severity of CTS is defined by clinical symptoms and electromyography (EMG) results. These patients will then be recruited for baseline studies, motor unit number estimation (MUNE). Motor unit number estimation is an EMG technique that quantifies the amount of motor units a muscle contains. In various forms of neuropathies, the MUNE decreases. For our study, patients will be included only if their MUNE is 2 standard deviations below normal. These patients will be identified from referrals to plastic surgery clinics or EMG clinics for management.Pre-study Screening and Baseline Evaluation The subject will have a complete physical exam including clinical labs and an ECG. Only those who have normal laboratory and ECG findings will be enrolled in the study.
