Controlled mild pain signals improve prosthetic hand grip precision in study

Bioengineer.org reported that researchers have tested a controlled mild-pain tactile feedback system designed to improve how people control prosthetic hands. The study found that delivering mild pain sensations significantly reduced grasp errors compared with visual and force feedback during virtual human-in-the-loop experiments. [1]

According to Bioengineer.org, the study was conducted by Elif Hocaoglu of the Living Robotics Laboratory at Istanbul Medipol University. The system sends a mild sensation of pain to intact skin whenever a prosthetic grip slips or makes an error, helping replace missing sensory touch information. [1]

Bioengineer.org reported that the research findings were published in the journal Frontiers in Neurorobotics. The method aims to restore natural feedback streams that notify the brain when an object is slipping or being crushed. [1]
