Carpal tunnel syndrome (CTS) is the most frequent entrapment neuropathy. Patients commonly experience neuropathic pain, leading them to seek medical advice. However, other symptoms experienced in patients with CTS, such as paresthesia, dysesthesia and allodynia, classed as positive sensory symptoms (PSS), are often under‑reported. In the present study, patients with surgically‑managed CTS were observed pre‑ and post‑surgery to evaluate PSS, using the symptoms scale component of the Boston Carpal Tunnel Questionnaire (BCTQ) and the Sensory Frequency of Symptoms Scale. In total, 19 patients were included in the present study, with 79% female patients, and a mean age of 54±10.59 years. In addition, the mean follow‑up was 63±29.91 months. The results of the present study revealed a pre‑surgery BCTQ score of 3.52±0.63 and a post‑surgery BCTQ score of 1.58±0.61. Notably, improvements in pain were observed, at 7.7±2.26 pre‑surgery compared with 1.65±2.88 post‑surgery. Compared with pre‑surgery, post‑surgery paresthesia scores were reduced from 2.94±0.82 to 0.47±0.45, dysesthesia scores were reduced from 2.52±0.84 to 0.47±0.39 and allodynia scores were reduced from 0.63±0.75 to 0.26±0.47. In conclusion, the results of the present study demonstrated that median nerve decompression ameliorated CTS symptoms, such as paresthesia and dysesthesia. However, further investigations are required to verify the benefits of surgery in relieving allodynia.
