This completed clinical study evaluated whether a structured eccentric training program reduced pain and improved hand and wrist function in adults with medically diagnosed de Quervain's tendinopathy whose symptoms had persisted despite previous conservative treatment.
The main questions addressed were:
* Did eccentric training reduce pain intensity and the extent of pain distribution in participants with de Quervain's tendinopathy?
* Did eccentric training improve hand and wrist function in daily activities and work-related tasks? Participants received a structured eccentric exercise program for 8 weeks. After instruction by a physiotherapist, they performed the exercises at home 1 to 5 times daily, at least 5 days per week, and adherence was monitored during supervised visits. Participants also recorded exercise sessions in a calendar.
Assessments were conducted at baseline and at week 8 and included pain evaluation, pain-area mapping, and validated hand and wrist function questionnaires. For participants with insufficient adherence or incomplete recovery, the intervention period was extended to 12 weeks, with an additional assessment at week 12. Post-treatment follow-up was specified in the study protocol at weeks 10 and 12 and approximately 6 months after treatment initiation.
