Investigation on lumbar load caused by different diaper changing methods

Abstract

Caregiver back pain is an important problem in the nursing care field, and diaper changing is considered to be particularly stressful on the lower back. In this study, we compared the lumbar load of multiple diaper changing postures and methods using a musculoskeletal simulator based on movement data from an IMU sensor and hand load data from a hand load measuring device. As a result, clear differences in lumbar load were observed depending on the changing method, and suggestions for load reduction methods were obtained.
