A newly developed bionic arm combines motor control with touch and hand movement sensations, allowing those with upper-arm amputations to behave and react as though they haven't lost their limb.
MIT researchers have developed a new, lightweight robotic hand that provides tactile feedback and is dexterous enough to perform tasks like zipping a suitcase and pouring juice.
A newly developed robotic thumb imprints how the hand is represented in the brain. Using the robotic thumb, researchers reported improvements in conducting dexterity tasks, such as building with blocks. Additionally, those who trained to use the additional thumb began to feel as though the digit was a part of their body.
Reconnecting muscle pairs during surgery following amputation provides patients more sensory feedback from the limb, researchers report.
Sensory signals transmitted from a prosthetic leg to the nervous system helps amputees perceive their prosthetic limb as part of their body. The new neurofeedback helps them perceive the new limb as significantly lighter.
Researchers have developed a new model that represents the planning of movement from seeing an object to grasping it.
