Objective Exploring scientific and applicable human-mechanics optimum indexes for foundational ergonomics evaluation of spacesuit gloves. Methods Thirteen subjects (7 males) were tested under two experimental conditions: bare hand and with the simulated spacesuit glove. The experimental parameters included five ergonomics items, such as strength, fatigue, tactile perception, maximum range of motion (ROM) and dexterity. In addition, 28 testing indexes that were optimized by statistics and knowledge of anthroponomy were integrated in the experimental parameter set as well. Results “Grip force”, “subjective fatigue and performance decline”, “adduction/abduction, flexion /extension and rotation”, “shape perception” and “screw nut and knot tying” were chosen as the optimum test indexes for strength, fatigue, maximum ROM, sense-perception and dexterity. Conclusion Our results provide essential data for ergonomics research and can be practically applied for improving the performance of the spacesuit gloves.
