Physical restraints have been commonly used in health care settings for people with challenging behaviours. The function performance of restraint garments in relation to their design attributes is evaluated so as to optimise the protection and safety of patients. In contrast to the traditional approach of evaluating fabric properties, this study proposes a practical and systematic approach in which the effects of the design attributes of restraint garments can be evaluated based on their unique functions of mobility control, safety and practical use of restraint in medical/healthcare settings. The design and performance of traditional restraint vests are assessed and compared against two new prototypes of restraint garments m terms of the amplitude of arm movement, garment interface pressures and displacements of 3D motion coordinates by using the Novel Pliance X pressure and motion capturing system. The results reveal that design attributes affect the performance of mobility restriction and safety of restraint garments. Necklines with collar piping and the use of reinforcement seams to withstand continuous stress during struggling may lead to extremely high interface pressures at the neckline and armholes, which result in ischemia injuries and even potential strangulation.
