Abstract
Based on a pneumatic artificial rubber muscle to restrict trunk twisting range of motion, an intelligent corset was developed to support the rollover movement of cancer bone metastasis patients. The specifications of the intelligent corset were determinated so that it could perform in the same way as a traditional hard corset. Furthermore, based on the permitted trunk twist angle derived from interviews with hospital nurses, systems of the intelligent corset were evaluated for detecting the intention of rollover, recognizing rollover, and restricting trunk Range of Motion(ROM). Through experimentation, the effectiveness of the intelligent corset in rollover movements was confirmed by comparing its capability to restrict ROM with that of the customized hard corset. Additionally, it was found that the intelligent corset solved the pressure/constant restriction problem that patients have with the hard corset.
