The impact of temperament on functional and symptomatic relief and satisfaction after carpal tunnel release

Abstract

The aim of this study was to compare the symptomatic, functional and satisfaction outcomes of patients with different temperaments undergoing carpal tunnel surgery by a single surgeon. Dominant temperaments of 171 patients with carpal tunnel syndrome were determined using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A). Patients were divided into six temperament groups, and the impact of their respective group measured against preoperative and postoperative symptom severity and functional capacity using the Boston Carpal Tunnel Questionnaire (BCTQ] and satisfaction using the Patient Evaluation Measure (PEM). Patients in the depressive group had the largest improvement in symptoms (BCTQ score change, –2.2) as well as a significant improvement in function (BCTQ score change, –2.1), yet had the lowest postoperative satisfaction (mean PEM score 9). Determination of patient temperament before surgery for carpal tunnel syndrome (CTS) may be useful as an ancillary technique to help predict postoperative satisfaction, which may in turn help guide preoperative communication and expectation setting.
