移動援助動作時の腰部負担評価を目的としたアセスメントツール (TAMAツール) の開発 : 上方移動版における妥当性と信頼性の検証

抄録

  The aim of the study was to construct an observation tool for assessment of the amount of the low back load during transferring patients on bed, and to evaluate the validity and reliability of the tool. The tool consists of 18 items arranged in three parts: working environment, posture stability, and movement efficiency. In validity of the experiment, 14 nurses performed repositioning up in bed to a standardized patient. Their movements were recorded, and the joint angles, distances, compressive forces (Fc) to the L5/S1 were calculated. The overall score was moderately related to the maximum and average Fc (r = -0.42, p < 0.01 and r = -0.52, p < 0.05). In reliability of the experiment, five observers checked 19 patterns of repositioning up in bed, performed by one nurse. The intraclass correlation coefficients were over 0.80 in the inter-observer reliability, and were over 0.70 in the intra-observer reliability. Therefore, the validity and reliability of this tool were satisfactory, and the results suggest that this tool is a useful test for assessing the risk of musculoskeletal disorders related to patient transfer
