Boston Carpal Tunnel Outcomes Questionnaire (BCTQ)
What It Measures
The Boston Carpal Tunnel Questionnaire (BCTQ) is the standard patient-reported measure for carpal tunnel syndrome. Rather than testing the hand, it asks the person about their own experience over the past two weeks — how bad the symptoms are and what the hand can still do.
Two scales run separately. The Symptom Severity Scale has 11 questions covering pain, tingling, numbness, weakness, night-time symptoms, and trouble gripping. The Functional Status Scale has 8 questions rating difficulty with everyday hand tasks such as writing, buttoning, holding a book, and opening jars. Each item is scored 1 to 5, and each scale is averaged rather than summed, giving two scores from 1 to 5 where higher means worse. The two are reported separately, not combined.

Additional Notes
Learn More: The minimal clinically important difference for the Symptom Severity Scale is about 1.0 point, so a drop of a full point after treatment reflects change the person actually notices. No definitive MCID has been established for the Functional Status Scale.
