The Prevalence of Pronator Teres among Patients with Carpal Tunnel Syndrome: Cross-sectional Study
[摘要] Theaim of conducting this study was to determine the prevalence of PTS amongpatients with carpal tunnel syndrome. The study wasconducted from March 2014 to April 2015 in the EDX ward and clinic of physicalmedicine and rehabilitation at the university hospital; Baqiytallah, a largereferral practice and research center in Tehran. We included patients withclinical symptoms and signs of CTS. Clinical assessments were aimed to thediagnosis of CTS and PTS. At the next stage, ultrasound study was performed forthe participants with suspected CTS. Sample size calculations were based on theformula: Results showed that 13(8.8%) patients presented electrodiagnostic,and 27 (18.2%) had clinical manifestations ofpronator teres syndrome of which, 17 showed ultrasonic signs of thesyndrome. In addition, 2, 7, and 8 out of the 17 patients had mild, moderate,and sever carpal tunnel syndrome, respectively. Age was not significantlydifferent between the patients with, and without pronatorteres syndrome (p-value=0.179).Nine participants with pronator teres syndromewere male and there was a significant difference concerning sex (p-value=0.013). There was a goodagreement between electrodiagnostic andultrasound findings (Cohen’s kappa coefficient=0.71, p-value<0.0001). Taken together, pronatorteres syndrome should be considered as a possibility among patients with carpaltunnel syndrome especially in sever forms. Both electrodiagnostic andsonographic studies are efficient for diagnosing pronator teres syndrome. Menare more prone to develop pronator teres syndrome.
