Typical Muscle Endurance Force Analysis of Upper Limb Pre and Post the Bed Test Using Detrended Fluctuation Analysis
(0) In order to evaluate the state change of the muscle force of the upper limb for the astronaut after a long time space flight,a bed test is designed to analyze the human performance of this ergonomics problem.The Detrended Fluctuation Analysis (DFA) technique is utilized to evaluate the change situation of the muscle force data.First,some typical force measurement devices are developed and utilized to collect the typical motion force data of the upper limb.Second,a bed test is implemented to get the data of different muscle states:1) we select 8 subjects to lie on the bed for 45 days; 2) we measure some typical operation force data,such as push and pull,etc,before and after the 45-days bed rest by the typical force measurement devices above.Third,we select the endurance force of some typical motions as samples and employ the DFA method to analyze the fluctuation of them.Finally,we use the results of DFA to estimate the health state of the subjects.Experiment results show us that the typical endurance forces of the subjects pro and post the bed test have a dramatic discrepancy.So this result can be utilized to analyze the health state and build the evaluation method for the astronaut who works in the space station for long time journey.
