New robotic device helps spine injury patients sit more comfortably: Study


NEW YORK: Researchers, together with one in all Indian-origin, have invented a robotic device that can be used to help and train other people with Spinal Cord Injuries (SCIs) to take a seat more stably, an advance which would possibly assist the restoration of sufferers with SCI.
According to the researchers from Columbia University in the United States, the robotic device - the Trunk-Support Trainer, or TruST - is a motorised-cable pushed belt positioned on the torso of other people with SCI to decide their keep watch over limits of posture, and workspace house while sitting.
They said the device delivers forces on the torso when the consumer plays upper body actions past the postural steadiness limits while sitting.

The study, revealed on Monday within the magazine Spinal Cord Series and Cases, is the primary to measure and define the sitting workspace of sufferers with SCI in response to their active trunk keep watch over.

"We designed TruST for people with SCIs who are typically wheelchair users," said study co-author Sunil Agrawal from Columbia University.

"We found that TruST not only prevents patients from falling, but also maximizes trunk movements beyond patients' postural control, or balance limits," he added.

Five subjects participated in a pilot study analyzing TruST with the Postural Star-Sitting Test.

In this customised postural test, the individuals have been required to observe a ball with their head and move their trunk as far as imaginable, without the usage of their palms.

The users repeated the test in eight directions, following which the researchers used the effects to compute the sitting workspace of each individual.

TruST was once customized for each matter, the researchers said, in order that they may practice customized assistive drive fields on the torso while the individuals performed the same actions once more.

With the brand new robotic device, the themes could reach further all over the trunk excursions in all eight directions.


According to the study, TruST significantly expanded the sitting workspace around their bodies, on a mean of about 25 in step with cent more.


"The capacity of TruST to deliver continuous force-feedback personalized for the user's postural limits opens new frontiers to implement motor learning-based paradigms to retrain functional sitting in people with SCI. We think TruST is a very promising SCI rehab tool," said study co-author Victor Santamaria, a bodily therapist at Columbia University.


Agrawal and his crew are now exploring using TruST to make stronger the trunk keep watch over of adults and kids with SCI.


"The robotic platform will be used to train participants with SCI by challenging them to move their trunk over a larger workspace, with TruST providing assist-as-needed force fields to safely bring the subjects back to their neutral sitting posture. This force field will be adjusted to the needs of the participants over time as they improve their workspace and posture control," Agrawal said.
