What is Maximum Perceived Strength

An analysis of different objects of daily use was made, specifically four models of lemon squeezers, three models of can openers, and four models of clothespins. Such analysis is made focusing on the strength needed to complete the task and the dimensional relation between the hands and object grips that impact both in ease of use and user well-being itself, identifying the gap between young and older adults characteristics and capabilities and the features of the object. This comparison was supported by a dynamometric study to identify the maximum capabilities of strength application in two different grip forces very common in daily life. These two grip forces are the ground of the interaction with the analyzed products. In conjunction with the force, the registry made an anthropometric assessment of different anatomical points in the hands.
