摘要

Purpose: The present study aimed to adapt cross-culturally, a German version of the Boston carpal tunnel syndrome questionnaire (BCTQ) for carpal tunnel syndrome.
Materials and Methods: A consecutives series of 53 patients (m:f=32:31, 59 +/- 14a, range 30-87a) with carpal tunnel syndrome completed the BCTQ that consists of a symptom severity scale (SS) and a functional status scale (FS). The BCTQ was translated due to the published and well known guidelines. Internal consistency was tested. For testing test-retest reliability the patients completed the BCTQ another time 24 hours after the first test. Validity was tested by comparison with a German Version of the Disability of the Arm, Shoulder and Hand questionnaire (DASH-G) [consisting of symptom scale (DASHSS) and functional scale (DASHFS)], "SF-36 Health Survey", the visual analogue scale (VAS) and electrodiagnostic testing (by using the distal motor latency (DML) and the sensoric antidromic velocity (SNAV)].
Results: Cronbach's alpha coefficients for SS and the FS were for the SS 0.893 and FS 0.941 respectively showing a good internal consistency. The test-retest reliability for SS and FS was also significant (difference between the two tests (mean): -0.02 (SD 0.16, according 95% confidence interval: - 0.08, 0.04)) and - 0.09 (SD 0.25, 95% confidence interval: -0.18, 0.01), Wilcoxon signed rank test: p = 0.2186 and p = 0.0605, Spearman correlation coefficients: r=0.98, p<0.0001 and r=0.97, p<0.0001, intra-individual class coefficients: 0.98 and 0.97). When testing validity, we could find a significant correlation between SS und DASHSS, and between FS and DASHFS (Spearman correlation coefficient: 0.83 p<0.0001 and 0.9/p<0.0001), and between SS und DASHFS and between FS and DASHSS (Spearman correlation coefficient: 0.68/p < 0.0001 and 0.58/p<0.0001), and also between SS and all subscales of SF-36 (Spearman correlation coefficient ranged from -0.4 to -0.73/p=0.0028 to p<0.0001) and between FS and the subscales of SF-36 (Spearman correlation coefficient: from -0.28 to -0.55/p=from 0.0455 to p<0.0001) except the subscale "Social functioning" (Spearman correlation coefficient: -0.24/p =0.0812).We also found significant correlations between SS and DML, and between SS and SNAV (Spearman correlation coefficient: 0.32/0.0173 and -0.28/0.0448). There was no significant correlation between FS and DML or FS and SNAV (Spearman correlation coefficient: 0.09/0.5334 and - 0.03/0.8351).
Conclusions: The present German version of the BCTQ has been documented to have sufficient internal consistency, reliability, and validity to assess the health status in carpal tunnel syndrome.
