Abstract
This research measured and analyzed multi-parameter based posture balance after 24hours of sleep deprivation. The correlation of multi-parameter was determined by measuring and analyzing muscle activity, somatosensory, vestibular, central nervous system, stability and BMI with different posture in circadian condition.Body movement were check every 2 hours of interval after 24 hours of sleep deprivation.12 electrodes were used to check the movement of muscle of body. There were 13 subjects and average age was 25.5. Signals of vision, vestibular, somatosensory, central nervous system, stability, fall index, weight distribution, BMI is collected by using Treadmill, Cycle ergometer, force plate showing body motion to stay in balance.Comparing PO and PC, PC is evaluated as more influential factor in stability part. WDI seemed to be a statistical significance test and has big influential to posture balance. Looking at the time change of multi-parameter measured from physical sensory organ in PO balance posture, there was current of circadian change in vision, vestibular and stability. In the same posture measuring mean value by each method of measuring, mean value of vision and stability was almost same and there was decrease of mean value in vestibular and somatosensory and central nervous system and fall index showed big number of mean value.Looking at the time change of multi-parameter measured from physical sensory organ in PC balance posture, stability shown over 10% higher. By measuring each way of method in same posture, vestibular and stability shoed higher mean value.There is a significant difference between body position of hip and knee(A) to measured value of posture position for circadian in balanced condition. Shoulder movement decreased 4times but hip and knee(A) decreased 20 times loading more work on muscles increasing fatigue in walking posture. with change of measured value after sleep deprivation shoulder increases but knee(p) decreases and hip gradually decreased. There was statistical significance.In hips considering circadian posture position than other part of the body in walking posture. Muscle work decrease by some what from 10times and 100times in cycling posture, the overall muscle activity flows to negative current. At initial time and sleep deprivation shows that body works forward by biggest value in the neck. Therefore neck, hip, knee(A) part works forward than head, shoulder, knee(A) showing positive value in circadian condition. There is a pattern difference of movement of body in 24 hours of sleep deprivation. Movement of neck, shoulder, hip and leg is influential while opening the eyes and closing the eyes were confirmed. There is a need to check movement of body in many conditions after 36 hours of sleep deprivation and loading heavy body workage to measure the ability to control lung and body.
