Phantom Limb Sensation Explained
A new study reveals functional changes occur among sensitive and motor brain regions following amputation. The findings shed new light on why some people feel phantom limb sensations following the loss of a limb.... Read More...
Brain Hand Map is Maintained in Amputees with and Without Phantom Limb Sensations
A new MRI study reveals the brain retains neural 'fingerprints' of a missing hand, decades after amputation and regardless of whether the person experiences phantom limb sensations. ... Read More...
Rerouting Nerves During Amputation Reduces Phantom Limb Pain Before it Starts
Researchers report using primary targeted muscle reinnervation during amputation helps to reduce, and in some cases, prevent phantom limb and stump pain in patients.... Read More...
Amputation Injury is Communicated to Opposing Limbs
Researchers report that following amputation of one limb, the bioelectrical properties are immediately reflected in the undamaged, opposing limb.... Read More...
New Theory for Phantom Limb Pain Points the Way to More Effective Treatment
Researchers present a new theory which states, following amputation, the neural circuitry connected to the missing limb becomes entangled with other neural networks, specifically ones responsible for pain perception.... Read More...
New Techniques Show Prosthetics Users Rely on Intact Limb
A new study that utilized electronic sensors discovered prosthesis users rely more heavily on their intact limbs to perform every tasks in their daily lives.... Read More...
Surgical Technique Improves Sensation and Control of Prosthetic Limbs
Researchers have developed a new neural interface that is able to relay commands from the central nervous system to a robotic prosthesis.... Read More...
A Way to Restore Movement Sensation in Upper Limb Amputation Patients
Researchers have developed a new method of restoring movement sensation for upper limb amputees. The researchers used small robots to vibrate muscles in order to 'turn on' movement sensations.... Read More...
Bionic Reconstruction: Restoration at the Psychological Interface
Researchers publish guidelines to help determine whether a patient is psychologically suitable for bionic hand reconstruction following amputation.... Read More...
Brain Remaps Itself in Child with Double Hand Transplant
Researchers report massive cortical reorganization was reversed in a child who received a double hand transplant following amputation in infancy.... Read More...
How Hand Amputation and Reattachment Affect the Brain
Researchers have discovered specific neurochemical changes in brain regions associated with brain remapping following amputation. Also, these changes may persist once the limb is reattached.... Read More...
