Purpose: We aimed to make a comparison of Boston Questionnaire scores with provocation tests and findings of
electrophysiological studies in patients with a carpal tunnel syndrome.
Materials and Methods: The Boston Questionnaire was applied preoperatively for 248 hands in 142 patients with an idiopathic carpal tunnel syndrome. Boston Questionnaire scores were compared with provocation tests (Phalen¡¯s test, Tinel¡¯s sign, compression test and hand elevation test) and electrophysiological findings.
Results: Correlation study between the Boston Questionnaire scores and electrophysiological findings showed that the electrophysiological findings correlated more with symptom severity score (Spearman coefficient, 0.545; p<0.01)
than with functional status score (Spearman coefficient, 0.307; p<0.01). Symptom severity score and functional status scores of the Boston Questionnaire correlated more linearly with the hand elevation test than with other provocation tests.
Conclusion: This study demonstrates a high correlation of Boston Questionnaire scores with the electrophysiological findings and the hand elevation test.
