The onset of low back pain in long-term care workers is remarkable, and 55.6% of the nursing care workers who have symptoms develop low back pain within 2 years after the long-term care work. These factors include moving assistance and repositioning for care-receiver. In actual long-term care, it is said that it is necessary to change the position for care-deceiver once every four hours using pressure-dispersing bedding. However, it is difficult to give nursing and judge the risk of pressure ulcer propery unless the person is a nurse, care manager, or other knowledgeable person. It is possible to measure the force according to each person with this mechanism, so it becomes possible to prevent pressure ulcers by changing the position. Ultimately, we believe that by providing feedback while measuring shear force and pressure, we can expect automation of nursing care that requires specialized knowledge.
