PHALEN TEST POSITIVATION TIME AND ITS CORRELATION WITH ELECTRONEUROMYOGRAPHY

ABSTRACT Objective: To compare the classification of CTS by the Phalen test with electromyography. Methods: Cross-sectional observational study. Patients at orthopedic outpatient clinic with carpal tunnel syndrome were evaluated by the Phalen test and compared with the result of the electroneuromyography. Results: Sample of 33 patients, mostly women (87.9%). Most patients were already diagnosed with severe CTS by ENMG. The results of the Phalen test and the electromyography were equal in 26 of the 33 patients (78.8%). Conclusion: The Phalen test showed its applicability, since it had results similar to those of ENMG in most cases, especially in the most severe ones. The exam studied is a possible tool for the classification and recommendation of surgical treatment. Level of evidence IV, Retrospective observational study.
