A new diagnostic test for carpal tunnel syndrome
JA Durkan
A new test, called the carpal compression test, consists of application of
direct pressure on the carpal tunnel and the underlying median nerve. The
results of the Tinel percussion test, the Phalen wrist-flexion test, and
the new test were evaluated in thirty-one patients (forty-six hands) in
whom the presence of carpal tunnel syndrome had been proved
electrodiagnostically, as well as in a control group of fifty subjects. For
the diagnosis of carpal tunnel syndrome, the carpal compression test was
found to be more sensitive and specific than the Tinel and Phalen tests.
