正確使用身體力學（Body mechanics）能保護護理師的肌肉骨骼系統，並提高搬運病人的安全性。核心原則是將物品（病人）盡量靠近身體重心，以減少對下背部產生的力矩（torque）；同時應採取寬基底站姿（雙腳分開與肩同寬）、屈膝以利用腿部大肌群施力、保持背部挺直，並避免在搬運過程中扭轉軀幹。錯誤動作如扭轉腰部、雙腳併攏、彎腰提物，皆會將過量壓力集中於腰椎，是造成醫療人員職業性下背傷害的主要原因。
Correct body mechanics during client lifting require keeping the object close to the center of gravity to reduce torque on the back and maintaining a wide base of support for stability. Nurses should avoid twisting the torso, bending at the waist, or standing with feet close together, as these actions increase the risk of lumbar strain and injury.
