Background and Aims: The Boston Carpal Tunnel Questionnaire is the most commonly used outcome measure in the assessment of carpal tunnel syndrome. The purpose of this study was to translate the original Boston Carpal Tunnel Questionnaire into Finnish and validate its psychometric properties. Materials and Methods: We translated and culturally adapted the Boston Carpal Tunnel Questionnaire into Finnish. Subsequently, 193 patients completed the Finnish version of the Boston Carpal Tunnel Questionnaire, 6-Item CTS Symptoms Scale, and EuroQol 5 Dimensions 12 months after carpal tunnel release. The Boston Carpal Tunnel Questionnaire was re-administered after a 2-week interval. We calculated construct validity, internal consistency, test–retest reliability, and coefficient of repeatability. We also examined floor and ceiling effects. Results: The cross-cultural adaptation required only minor modifications to the questions. Both subscales of the Boston Carpal Tunnel Questionnaire (Symptom Severity Scale and Functional Status Scale) correlated significantly with the CTS-6 and EuroQol 5 Dimensions, indicating good construct validity. The Cronbach’s alpha was 0.93 for both the Symptom Severity Scale and Functional Status Scale, indicating high internal consistency. Test–retest reliability was excellent, with an intraclass correlation coefficient greater than 0.8 for both scales. The coefficient of repeatability was 0.80 for the Symptom Severity Scale and 0.68 for the Functional Status Scale. We observed a floor effect in the Functional Status Scale in 28% of participants. Conclusion: Our study shows that the present Finnish version of the Boston Carpal Tunnel Questionnaire is reliable and valid for the evaluation of symptom severity and functional status among surgically treated carpal tunnel syndrome patients. However, owing to the floor effect, the Functional Status Score may have limited ability to detect differences in patients with good post-operative outcomes.

Objetivo: Evaluar los resultados de la retinaculotomía endoscópica para tratar el síndrome del túnel carpiano mediante la técnica de doble portal de Chow, entre enero de 2006 y diciembre de 2015. Materiales y Métodos: Estudio de 179 pacientes (edad promedio 48.2 años [rango 32-68]), con 217 casos de síndrome del túnel carpiano idiopático y un seguimiento promedio de 97.9 meses. Los pacientes eran 145 mujeres (81%) (31 bilaterales) y 34 hombres (19%) (7 bilaterales) y fueron evaluados con la Symptom Severity Scale (SSS) y la Functional Status Scale (FSS) del Boston Carpal Tunnel Questionnaire (BCTQ). Resultados: El puntaje medio de la SSS-BCTQ fue de 3,20 + 0,26 antes de la cirugía, mejoró a 1,30 + 0,12 a los 6 meses y se mantuvo en 1,25+ 0,11 a largo plazo. El puntaje medio de la FSS-BCTQ fue de 2,57 + 0,29 antes de la cirugía, mejoró a 1,28 + 0,18 a los 6 meses y se mantuvo en 1,20 + 0,09 a largo plazo. Hubo 7 casos (3,2%) de neuropraxia posquirúrgica transitoria. No hubo conversiones a técnica abierta. Conclusión: La liberación endoscópica del túnel carpiano con la técnica de Chow es un método quirúrgico eficaz y seguro para tratar el síndrome del túnel carpiano idiopático.

No consensus exists about the minimal clinically important difference for the Boston Carpal Tunnel Questionnaire, which hampers its clinical application. This study assessed the minimal clinically important difference of this questionnaire. The Boston Carpal Tunnel Questionnaire was completed by 180 patients, with clinically defined carpal tunnel syndrome, preoperatively and at about 8 months follow-up after carpal tunnel release, together with a six-point scale for perceived improvement. Receiver operator characteristics curves showed that relative changes in Symptom Severity Scale and Functional Status Scale scores correspond better to a clinically relevant improvement than absolute changes. The minimal clinically important difference should be individually calculated from baseline Symptom Severity Scale and Functional Status Scale scores, as patients experiencing more symptoms require more improvement to notice a clinically important difference. By taking this into account, the Boston Carpal Tunnel Questionnaire is more meaningful as an outcome measure in research and clinical practice.

INTRODUCTION: Carpal tunnel syndrome (CTS) is the most common entrapment syndrome of median nerve causing frequent disability especially among working populations. Boston Carpal Tunnel Questionnaire and Electrophysiological study helps in detecting and aiding in the diagnosis of CTS and helps in determining level of improvement after surgical release of carpal tunnel. OBJECTIVES: To assess functional outcome of patients with Carpal Tunnel Syndrome after surgery as assessed by Boston Carpel Tunnel Questionnaire and Electrophysiological study. METHODS: A prospective observational study conducted over a period of one year (January 2017 to January 2018). The study was conducted among consecutive 31 electrophysiological conrmed carpal tunnel syndrome attending the outpatient department of Physical Medicine and Rehabilitation, Government Medical College, Thiruvananthapuram. All patients underwent open carpal tunnel release. Functional outcome was assessed using Boston Carpal Tunnel Questionnaire (BCTQ) both preoperatively and at interval of 3 weeks, 6weeks and 3 months postoperatively. Electrophysiological study assessed using nerve conduction study both preoperatively and 3 weeks post operatively. Data was entered in Microsoft excel and analyzed using SPSS statistical software. RESULTS: The study involves 31 conrmed cases of Carpal tunnel syndrome patients. Mean Boston Carpal Tunnel Questionnaire (BCTQ) score preoperatively was 58.52 ± 12.73 which was markedly improved postoperatively at 3weeks with mean score of 29.77±6.68. At 6 weeks and 3 month follow up period it was reduced respectively to mean score of 23.94±4.23 and 22.94±4.62. Preoperative NCS shows decreased conduction velocity with mean nerve sensory velocity (NSV) score 21.51±8.19 and mean nerve motor velocity (NMV) score of 20.72±8.81 which statistically improved following surgery with mean NSV score of 32.04±9.01 and mean NML score of 33.78±8.1. Correlation between pre- and post-operative BCTQ and NCS parameters shows positive correlation with latency and negative correlation with amplitude and conduction velocity. Increased latency and decreased conduction velocity associated with higher BCTQ score with signicant 'p' value (p<0.05). CONCLUSION: There is statistically signicant improvement of functional outcome following carpal tunnel release surgery assessed through Boston Carpal Tunnel Questionnaire and Electrophysiological ndings

Abstract Background The Boston Carpal Tunnel Questionnaire (BCTQ) and its shorter version, the Six-Item Carpal Tunnel Symptoms Scale (CTS-6), are widely used for assessing function and/or symptoms in patients with carpal tunnel syndrome. This study examined the structural validity of the BCTQ and CTS-6 among patients who had undergone surgery for treatment of carpal tunnel syndrome. Methods The data for this cross-sectional analysis were obtained from 217 adult patients who had undergone carpal tunnel release surgery 1 year earlier. All patients completed the CTS-6, Symptom Severity Scale (SSS) and Functional Status Scale (FSS) of the BCTQ at 12 months after surgery. The Rasch Measurement Theory (RMT) was applied to investigate the unidimensionality, residual correlation, differential item functioning, scale coverage/targeting, and person separation of the CTS-6, SSS and FSS of the BCTQ. Results The FSS showed unidimensionality and good scale and item fit. All items showed ordered response category thresholds. Eight of the FSS items displayed differential item functioning favoring age or gender. The multidimensional structure of the CTS-6 was absorbed by creating a testlet for frequency of symptoms or testlets for pain and numbness. The testlets supported unidimensionality in the BCTQ SSS. One item in the CTS-6 and two items in the BCTQ SSS showed differential item functioning favoring age or gender. Four items in the BCTQ SSS and two items in the CTS-6 exhibited disordered response category thresholds. Merging of the relevant response categories led to ordered response category thresholds. The person separation indices were 0.73, 0.86 and 0.77 for the CTS-6, BCTQ SSS and FSS, respectively. Conclusions Based on the RMT analysis, the CTS-6 has superior psychometric properties compared to the BCTQ SSS in surgically treated patients. The CTS-6 might be more accurate when separated into item sets measuring pain or numbness. The FSS of the BCTQ has acceptable construct validity, although gender differences at some ages were observed in responses.
