 note = {This study investigated the characteristics of nursing-care motions using electromyographic analysis and motion analysis. Six healthy young subjects (20 years old) performed 10 consecutive lifting and patient posturechanging motions on a bed, as well as 10 consecutive transferring motions from bed to wheelchair. Integral volume of electromyographic discharge per one second （iEMG) obtained from upper limb activity was remarkable during lifting and patient posture-changing motions, and lower limb activity was remarkable during transferring motions. The percent of iEMG to maximal muscle contraction was higher in erector spinae muscle compared to that in other muscle (deltoid, biceps brachii, flexor carpi radialis, rectus abdominis, vastus lateralis, tibialis anterior). Three subjects of 6 also performed lifting and patient posture-changing motions on a bed and transferring motions from bed to wheelchair with supportive device. The iEMG obtained from upper limb activity was reduced during lifting and patient posture-changing motions compared to without-device trial described above, but the iEMG was remarkable during transferring motions. The percent of iEMG to maximal muscle contraction was also higher in erector spinae muscle with supportive device compared to without-device trial. The angle between trunk and thigh showed increase of 33 degree during lifting compared to preparation point of the lifting. But there was no increase in the lifting and patient posture-changing motions with supportive device. The height of the neck showed the highest value at the midpoint of the transferring motion when subjects began to twist patient's body to the wheelchair from the bed. And the mean fluctuation in the height of neck was 28 cm. But there was no fluctuation in the height of neck in transferring motions from bed to wheelchair with supportive device. Lifting, posturechanging and transferring motions during nursing care practice are stressful motions affecting the whole body, especially the low back. It is suggested that using some supportive device during these nursing care motions would be useful for alleviating droopy posture and lift-down motion.},
