Comparison of Trigger Finger Orthotic Wearing Schedules: A Feasibility Study

Abstract Aim: This randomized prospective pre-post test, single-subject, case series (NCT04094389) feasibility study evaluated the feasibility of conducting a clinical trial to compare the effect of three different trigger finger orthotic daily wear schedules on digital triggering and pain level in adults with trigger finger. Methods: Nine participants enrolled through convenience sampling were randomly assigned to a wear group: continuous, sleeping, or waking. Descriptive statistics were utilized to describe participant demographics and examine the data for changes across the six to ten weeks of study. Results: The study successfully obtained feasibility data regarding participant recruitment rate, demographics, methods as well as orthotic wear comfort, functionality, adverse effects and wearing compliance. The rate of recruitment was 1.9 participants per month. Conclusions: The results suggest it is feasible to perform a RCT, though recruitment was challenging. Recruitment for a RCT may be facilitated by broadening the inclusion/exclusion criteria to obtain participants.
