Abstract
Opening child-resistant pill jars presents significant challenges for elderly individuals due to diminished hand strength, dexterity limitations, and conditions such as arthritis. This study examines the physical strain associated with opening such containers by analyzing grip force, pinch force, and torque requirements using hand dynamometers, pinch gauges, and torque meters. Prior research highlights the role of grip and pinch strength in opening containers, though effectiveness varies based on design. Studies also indicate gender differences in hand strength and the impact of wrist fractures on torque generation, further complicating accessibility. Observational analysis reveals that standard threaded caps are easier to open than child-resistant lids, yet the difficulty of opening these caps can lead to frustration and, in some cases, medication neglect. Additionally, the study identifies specific finger regions under strain during the opening process. A user-centered design approach was employed to develop mock-up models aimed at improving form and ease of operation. These findings underscore the need for accessible packaging solutions that balance safety with usability, ensuring elderly individuals can access their medications without excessive physical effort.
