Abstract

Objective: To identify predicting factors of treatment outcomes of a two stage group-based and then individual-based intervention programme for patients with carpal tunnel syndrome (CTS). Methods: A prospective cohort study where patients diagnosed with CTS were recruited from an out-patient occupational therapy clinic to join the two-stage CTS programme. The Stage-One programme consisted of splinting and educational talks in a group format, while the Stage-Two programme consisted of four weekly individual sessions providing psychosocial support, reinforcing correct ergonomics and mobilization. Baseline assessment on six potential predicting factors and four outcome measures was done for all patients. Patients were re-assessed at the end of the Stage-One and the Stage-Two programme. Analysis was done by binary logistic regression adjusted for baseline covariates. Results: One hundred and sixty-six patients completed the Stage-One programme and 46 patients also completed the Stage-Two programme. Results showed that the Chinese Symptom Severity Scale (SSS) baseline score was the only significant predictor for the Stage-One programme outcomes (AUC for ROC was 0.708) with an optimum cut-off score of 23.5. On the other hand, the Chinese QuickDASH baseline score was the only significant predictor for the Stage-Two programme outcomes (AUC for ROC was 0.801) with an optimum cut-off score of 27.4. Conclusions: The significant predictor for the Stage One Programme was the Chinese SSS baseline score and that for the Stage Two Programme was the Chinese QuickDASH baseline score. The optimum cut-off scores identified may be applied clinically to guide client-centered treatment planning.
