Adherence to intervention (DEFO). Legend: Top graph demonstrates NPRS pain data (fortnightly intervals), and lower graph indicates wear-time. Dotted lines on top graph indicate data noncompletion. Red dotted line (lower graph) set at 84 h (wear-time compliance threshold over 2 weeks). Graphs b*, c*, and d* indicate the Orthotimer data loss period with a shaded red area. Participant a* had data for the whole trial period — the DEFOs were remade due to poor fit. Total wear-time over whole intervention (hours) for participants a*, b*, c*, and d* was 51.5, 27.8, 72.5, and 276.5, respectively. Mean wear-time on days worn (hours) for participants a*, b*, c*, and d* was 2.6, 5.6, 4.3, and 8.9, respectively
