The influence of spaceflight on human upper limb movement control:a review and prospect
Accurate and efficient upper limb movement control is a critical guarantee for astronauts to complete their daily tasks in space.Exploring the laws and mechanisms of the influence of microgravity and nonspecific stressors(isolation,noise,fatigue,etc.)in spaceflight on astronauts'upper limb movement control is an important direction of spaceflight human factors engineering research.This article summarizes the research paradigms and findings of in-orbit upper limb movement control research,revealing patterns such as slowed movements and decreased motor control performance under high cognitive load in spaceflight.It also points out the potential mechanisms underlying the inconsistent research results under various research paradigms.On this basis,the paper addresses existing controversies and shortcomings in previous studies,and puts forward prospects and suggestions for subsequent in-orbit movement control research.
