Child-Resistant Packages (CRPs) are very important to prevent children under five years old to access products that are hazardous to their health. However, the opening mechanisms end up hindering the use of such packages by adults, the elderly, and people with disabilities. The aim of this study was to analyze the influence of a movement-restriction glove by collecting the torque exerted in an attempt to open 3 different squeeze-and-turn CRPs. The study enrolled 10 subjects, divided equally between men and women. The subjects performed the task with and without the glove. The results showed that the moment of force when the subjects were wearing the glove was higher than that obtained without the use thereof. Besides, the cap with the largest diameter offered the best conditions for torque transmission.
