Robotic exoskeleton brace analyses spine deformities

Known as RoSE (Robotic Spine Exoskeleton), the device consists of three rings placed on the pelvis, mid-thoracic and upper-thoracic regions of the spine. Attached to the rings are 12 limbs that feature a combination of actuators, joints and sensors. Through forces applied by these limbs, the robotic brace can analyse the condition of the spine, providing data that could be used to deliver corrective treatment tailored specifically to the needs of each wearer.

“The RoSE is the first device to measure and modulate the position or forces in all six degrees-of-freedom in specific regions of the torso,” said principal investigator Sunil Agrawal, professor of mechanical engineering at Columbia and professor of rehabilitation and regenerative medicine at the university’s Vagelos College of Physicians and Surgeons.

“To our knowledge, there are no other studies on dynamic braces like ours. Earlier studies used cadavers, which by definition don’t provide a dynamic picture."
