After a year of using a bionic arm, patients report subjective sensations did not shift to match the location of the touch sensor on their prosthetic device.
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.
Reconnecting muscle pairs during surgery following amputation provides patients more sensory feedback from the limb, researchers report.
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.
Adding a BCI that evokes tactile sensations makes it easier for users to manipulate and use robotic arm prosthetics.
Using virtual reality technology, researchers found the faulty alignment of prosthetics resulted in a measurable loss in performance for users.
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.
Using magnetic beads implanted into muscle tissue within the amputated residuum of animals, researchers have created a more precise way to control prosthetic limbs.
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.
