Kinematic Analysis of a Four-Bar Linkage for Forward Stroke Motion

Current adaptive kayak mounts designed for individuals with upper-body mobility impairments have significant limitations.While devices such as paddle holders and stabilizers improve accessibility, they often restrict natural movement patterns, reducing efficiency and comfort.This study highlights these shortcomings and presents a novel four-bar linkage mechanism as a potential solution.The proposed design aims to replicate a natural forward kayak stroke, improving both usability and alignment with user needs.Motion capture technology was used to analyse stroke mechanics and inform the design process.The effectiveness of the new system was assessed through user feedback and quantitative performance metrics, including motion accuracy and comfort.Results demonstrate that the four-bar linkage successfully mimics a natural forward stroke, suggesting its potential to enhance performance, inclusivity, and user satisfaction in adaptive kayaking.By addressing key limitations in existing designs, this study advances adaptive sports technology and contributes to the development of more functional and user-cantered equipment.
