Synthesising the roles of torque and sensation in pinch force: a framework

Abstract

Although studies show that torque and sensation are important factors to consider in grip force, there appears to be few frameworks that focus on their roles in pinch force. This study proposes a framework that potentially explains the roles of torque and sensation in pinch force. A review was done on these factors followed by a literature synthesis which categorised them into sub-factors. The sub-factors were combined to output a framework that explains the mechanisms of their interactions. This framework enriches the knowledge on pinch force levels for reduced injury risks by identifying preliminary factors that may influence pinch force. It can potentially be used to improve the effectiveness of manufacturing tasks. Although further research on it is required, it still provides researchers with more factors to consider for studies on occupational risks and injuries. With this framework, researchers can potentially improve predictions on functional outcomes in precision manufacturing tasks.
