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%)… Show more

“…This is due to potential false negatives in a ratio ranging from 16 to 34% [ 1 ]; and (3) the visual analogue Scale, which is highly recommended for measuring pain [ 49 ]. The reason why these tests are more frequently observed may be due to the poor diagnostic utility of other evaluation tools as described by Li Pi Shan R et al [ 50 ], despite the fact that the rest of the diagnostic instruments used in the studies have been to a lower or greater extent credited in other research activities [ 51 , 52 , 53 , 54 , 55 , 56 , 57 ].…”

“…Etiological factors include diabetes mellitus, obesity, hyperlipidemia, rheumatoid arthritis, hypothyroidism, recurrent twisting movements, and pregnancy; however, it is usually idiopathic [1,2,9]. The diagnosis of CTS is dependent on clinical presentations plus clinical tests, such as Phalen's test or Tinel's test [10,11]. The diagnostic modality of choice for CTS is electromyography/nerve conduction study (EMG/ NCS), which can be used to assess the severity of CTS [10].…”
