Efficacy of a newly designed trunk orthosis with joints providing resistive force in adults with post-stroke hemiparesis.

Background: Few studies have examined the efficacy of trunk orthoses that support the upper trunk and a paretic limb in stroke patients. To improve stability and alignment of the trunk and pelvis in hemiparetic patients, we developed a newly designed trunk orthosis that provides resistive force through spring joints.

Objectives: This study aimed to determine the newly designed trunk orthosis's biomechanical effects during level walking.
