Primary Outcomes

Description: Patients with CTS who obtained as a result of surgical treatment, remission of paresthesia were considered to be truly ill, and patients who did not receive remission of paresthesia were considered non-diseased. The remission of paresthesia evaluated after surgical treatment was considered the reference standard for the diagnosis of CTS. The accuracy of US was assessed by evaluating the results of the US (positive or negative) in relation to the results of surgery (remission of paresthesia or non-remission of paresthesia).

The accuracy of EMG was assessed by evaluating the results of the EMG (positive or negative) in relation to the results of surgery (remission of paresthesia or non-remission of paresthesia).

Description: The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) is a disease-specific STC questionnaire, self-administered, translated and validated for the Portuguese language, which evaluates two components: a symptom severity scale with 11 questions and a functional status scale with 8 issues. All patients in this study responded to two BCQT, the first after initial clinical evaluation and the second at the end of the fourth month of postoperative follow-up. To assess the improvement of severity and functional status of the patients in this study, a medically significant improvement in the two scales was expected between the means of the second Boston questionnaire (according to BCQT) compared to the means of the first Boston questionnaire (first BCQT).
