摘要：Despite wheelchair design being critical to improve the quality of life and health of individuals with mobility impairments, there was a paucity of detailed investigations into designing and assessing wheelchair lock actuating rods (WLAR). This study aimed to consider various limitations in the design of the WLAR: 1) explore the effects of gender and height on the perceived comfort of the WLAR, and 2) ascertain the optimal WLAR position. The Fifty participants were requested to assume a seated position within a wheelchair and operate the WLAR at different positions. A comfort perception questionnaire assessed the comfort of posture (sitting posture) and upper limbs (shoulders and wrists). The Kansei evaluation method was employed to establish the relationship between the gender and height ranges of the participants and their corresponding comfort scores. Finally, support vector regression was used to generate a prediction model for the Kansei scores associated with the WLAR position. The results showed that males and females exhibited higher comfort perception scores for the WLAR position K8 and position L7. In contrast, the Kansei scores for position K2 and position L3 are comparatively lower and situated closer to the original WLAR positions. In addition, positions with higher perception scores have better perceived comfort in participants' posture and upper limb operations. Based on the results, it is recommended to use the positions with higher perceived scores as the optimal range for the WLAR position design to reduce the risk of safe operation and improve the comfort of operation. This study evaluated the WLAR position and discussed the relationship between the position parameters and the WLAR design and operational comfort. The results of this study show that gender and height are important factors affecting the design of the WLAR position, and can provide a theoretical basis for the optimization design of the WLAR. ? 2025 The Authors.
