Abstract

Patient handling related musculoskeletal injuries are prevalent among Emergency Medical Service (EMS) providers. The first step in many patient handling situations is where a supine patient on the floor is brought to a sitting position. This study investigated whether a strap, placed under the patient's torso and long enough that EMS providers can perform the patient raising task in a standing posture, reduced muscular effort. Fifteen participants raised a simulated patient, with the help of an assistant, using the strap method and a traditional method (grasping the shoulders) in an open area, a restricted space, and in a bathtub. Torso postures improved in all location conditions when using the strap. The muscle activation data showed mixed results. While EMG responses from the latissimus dorsi muscles were reduced, EMG activity of the erector spinae muscles increased when the strap was used. Perceived effort assessments supported the use of the strap.
