Popis: Tablet crushing is a common practice used by patients and their carers, mainly to facilitate swallowing. Various tablet-crushing devices with different designs are currently available on the market. This study aimed to compare the usability of different tablet-crushing devices in people with and without limited hand functions. The hand function of 100 adults recruited from the general community (40 of whom self-reported a limited hand function) was assessed using the hand and finger function subscale of the Arthritis Impact Measurement Scale version 2. The hand strength was measured using a dynamometer. Participants crushed tablets using 11 crushing devices and completed a Rapid Assessment of Product Usability and Universal Design questionnaire for each device. Hand-held twist-action crushers with an ergonomic grip received the highest usability scores among both groups, irrespective of the cost (p < 0.05). Crushers with bags were scored lower by those with limited hand functions, although the score improved if the device was automatic. Preferences regarding electronic crushers significantly changed once the cost was revealed. Economical twist-action crushers with ergonomic grips and without bags or cups were the most favoured crushers.
