RESUMO
Introduction: De Quervain's tendinopathy affects the region of the wrist and the hand. Thumb motion becomes painful. This illness is caused by a degenerative process rather than inflammation. Primary treatment methods are splinting, taking non-steroid anti-inflammatory drugs and different physical therapeutic modalities, administration of a steroid injection into the tendon sheath or surgical release of the tendon sheath may be performed. Aim: The aim of the present study was to investigate whether conservative treatment complemented by eccentric training could provide an adequate alternative to the currently accepted treatment options. Method: The eccentric training lasted for 8 weeks (if necessary for 12 weeks). Following the introduction to exercises, patients (n = 9) repeated the training several times a day, which was controlled during weekly meetings. At the 1st, 8th and 12th meetings, inspection and the following measurements were performed: range of motion, muscle strength, evaluation and number of painful regions including the completion of patient questionnaires. Data were analysed with paired samples t-tests and repeated measures ANOVA. IBM SPSS Statistics 25.0 and Microsoft Office Excel Professional Plus 2016 programs were used. Results were regarded significant at level of p<0.05. Results: Significant improvements were found in the intensity of pain (Numeric Pain Rating Scale p = 0.005, n = 9) and in the functionality of the hand and wrist (Quick Disabilities of the Arm, Shoulder and Hand questionnaire part 1. p<0.001, part 2. p<0.001, Patient-Rated Wrist Evaluation questionnaire p<0.001; n = 9). Conclusion: With careful patient selection, conservative treatment complemented by eccentric training could be an alternative to current treatment options. Orv Hetil. 2020; 161(11): 419-424.
