Pressure relief and frequent repositioning help to mitigate complications associated with PUs. Manually moving a patient is a physically-demanding task that can lead to musculoskeletal disorders for the caregivers and skin abrasion for patients. The first study in this thesis reviewed devices (commercially-available or published research) that are meant to address patient pressure relief, repositioning and/or transfer while in a bed. The review findings indicated that current technologies have limitations such as design complexity, high cost, bulkiness, unidirectional patient transfer, and the need for a caregiver’s intervention. Inspired by waves in nature such as water waves that can carry objects, a proposed solution in the literature for patient transfer is to create traveling ways on a bed surface for multidirectional patient transfer and to minimize the caregiver’s physical effort for constant patient readjustment on the bed. Inspired by this idea, the second study in this thesis built upon prior work in the literature and presented the design requirements for moving a human body using traveling waves on a bed surface. Particularly, through kinematic analysis and simulation of traveling waves, this study explored how various wave parameters such as the wavelength, amplitude, frequency, and number of wave-generating actuators would affect human transportation speed and movement smoothness.
