Both groups of patients received identical orthotic wearing instructions. Patients were asked to use the orthosis during the nighttime and also during daytime ADL's for three to four hours per day. Each patient was also provided with a data collection sheet in order to control treatment adherence. All patients were asked to report any discomfort when using the orthosis. The orthosis was the only treatment intervention received by the participants. No therapeutic exercises, modalities or other complementary treatments were offered to the patients in order not to interfere with the individual effectiveness of the orthosis. Patients were contacted by telephone a week after and were ask about pain intensity. Three months after first evaluation, participants were cited in hand therapy clinic in order to collect again outcomes measurements.
