Summary

Study Design and Subject Recruitment: This was a cross-sectional study in a single centre outpatient setting at the Foot Care and Limb Design Centre, Tan Tock Seng Hospital. As this was a proof-of-concept clinical trial for the introduction of 3D printed AFOs as a patient service, only 5 subjects were recruited based on consecutive sampling.

Interventions: Thermoformed AFOs moulded over the subject's lower limb plaster model served as the control intervention. The plaster models were rectified by an orthotist with over 20 years of experience and the AFO design was determined according to the subject's clinical presentation and needs. The AFOs were manufactured from 4 - 5mm thick homopolymer polypropylene. 3D printed AFOs served as the treatment intervention. It was fabricated through 3D scanning with an Artec Eva 3D scanner (Artec 3D, Luxembourg, Luxembourg) and an adjustable Perspex glass foot plate, CAD modelling with the OrtenShape software (Proteor, Saint-Apollinaire, France), and printed using fused deposition modelling with the Fortus 450mc (Stratasys, Minnesota, United States). The 3D printed AFO is printed of Polyamide Nylon-12 material in the same thickness as the thermoformed AFO. There were no blinding procedures as both interventions were distinctly different and it is not possible to blind subjects with daily use of the AFOs.

Trial Schedule: A thermoformed and a 3D printed AFO were fitted to each subject in a single session. The QUEST survey was administered post-fitting. Subjects brought home both AFOs and were instructed to wear them during ambulation, alternating between the AFOs daily. Subjects returned for follow-up at 3 weeks and 6 weeks post-fitting for necessary adjustments and the administration of the QUEST surveys was repeated for each AFO.
