Comparison of 3D-printed and thermoformed orthosis fabrication methods for trigger finger and hyperextension of the proximal interphalangeal joint: a pilot study
Trigger finger and hyperextension of the proximal interphalangeal joint
The study design is semi-experimental; thus, there is no randomization, and there is only one arm for which the treatment is a 3D-printed orthosis. Every participant will wear the 3D orthosis and the thermoformed orthosis (control). They will wear each orthosis for a total of 2 months. The participants will answer a questionnaire assessing their symptoms before wearing the orthosis and questionnaires about the orthosis 24 hours, 1 week, 1 month and 2 months after beginning to wear the orthosis. They will not wear the 3D orthosis and the thermoformed orthosis at the same time.
