Abstract

Objectives: The study evaluated the sensitivity, specificity and predictive values of clinical tests in the diagnosis of carpal tunnel syndrome.

Subjects and methods: Prospective descriptive study, 69 adult Vietnamese patients with numbness and pain of hands at 175 Military Hospital from April 2019 to October 2019

Results: The highest sensitivity was found with Durkan’s compression test (95%) and the lowest was found with thenar atrophy (23%). The highest specificity and positive predictive values were found with thenar atrophy (100%) and the lowest were from the Tinel’s test (75% and 59%). The highest negative predictive value was Durkan’s compression test (83%) and thenar atrophy was the lowest (24%).

Conclusion: Thenar atrophy was highly specific in carpal tunnel syndrome but had limited value in early detection. Due to their low specificity, only one test do not appear sufficient enough to establish a definite carpal tunnel syndrome diagnosis. However, tests have valuable to suggest the diagnosis. It may be necessary to use a combination of clinical and paraclinical test to diagnose carpal tunnel syndrome
