RESUMO
People with trunk impairment cannot lean forward because of the dysfunction of the trunk resulting from events such as cervical cord injury (CCI). It is therefore difficult for such people to work at a table because they may easily fall from their wheelchair, and it is also hard for them to return to their original position. This limits the activities of daily living (ADLs) of people with trunk impairment. These problems can be solved to some extent with equipment such as a wheelchair belt or a spinal orthosis that can help the person to maintain his or her posture. However, people cannot move freely with this equipment. Furthermore, if this equipment is used for a long time, there is a risk of physical pain and skin issues. In this study, we developed a device that assists the trunk of people with trunk impairment when they lean forward. This device supports people with trunk impairment so that they may take their meals at the table and prevents them from falling over their wheelchair without hindering their daily performance when they are sitting normally. The effectiveness of our proposed device was verified by experiments involving having a meal, operating a wheelchair, and colliding with a curb. Our device can help people with trunk impairment by improving their ADLs and quality of life (QOL).
