Three days of training with brain-computer interface technology reduced phantom limb pain. Patients reported a 30% reduction in pain after one session, and the effect lasted up to five days after training was complete.
When the brain is deprived of input from a limb following amputation, it reorganizes its neural map and reroutes the function to the remaining limb.
Researchers have developed a sensor-instrumented glove for prosthetic hand controls which can sense pressure, temperature, and hydration using electronic chips sending sensory data via a wristwatch.
Visual responsiveness in the somatosensory cortex diminishes significantly following mirror therapy for phantom limb pain. Before therapy, researchers discovered a strong, unexpected activation in the sensorimotor foot region of amputees to visually presented images of the foot. This response was no longer present following mirror therapy.
At least four species of marine ribbon worms independently evolved the ability to regrow a head after amputation.
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.
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.
Researchers report using primary targeted muscle reinnervation during amputation helps to reduce, and in some cases, prevent phantom limb and stump pain in patients.
Researchers report that following amputation of one limb, the bioelectrical properties are immediately reflected in the undamaged, opposing limb.

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.
