초록
The purpose of this study is to obtain information necessary for the development of patient clothes that canreduce physical fatigue of caregivers by quantitatively measuring the muscle load and fatigue. The patient clothes usedin this study can be broken down into three types: A type (back center zipper open suit), B type (top-to bottom separatedpatient clothes), and C type (front zipper open suit). The EMG measurement sites are as follows: hand muscle (bra-chioradialis), upper arm (biceps, triceps), shoulder (anterior deltoid, medial deltoid, posterior deltoid, upper trapezius), andwaist (erector spinae); additionally, the EMG signals were measured. Through this experiment, muscle load, muscleenergy consumption, and muscle fatigue generation tendency were analyzed. The results of the study revealed that theC type patient clothes required the most strength in the muscles of the shoulders, upper arms, hands, and back whenbeing put on and taken off compared to other patient clothes. The A type clothes required a relatively large force in open-ing the zipper. In terms of muscle energy consumption, B type generally called for more strength when it came to thezip-up and putarmsup motions. With regard to the cover the body and put legs/hips up motions, C type used the highestamount of muscle energy, whereas A type used relatively little energy. In terms of the occurrence of muscle fatigue duringthe putting on and taking off of the patient's clothing, there was a difference in the area and degree of muscle fatigue inthe A, B, and C types, and there was also a tendency for muscle fatigue to occur when performing repetitive movements.
