[1] therapy used for the treatment of phantom limb pain and analysis of limb telescoping. In this image, the mirror helps to represent the patient's perception of their body. Limb telescoping is the progressive shortening of a phantom limb as the cortical regions are reorganized following an amputation. During this reorganization, proximal ...
Treatment with mirror therapy soon expanded beyond its origin in treating phantom limb pain to treatment of other kinds of one-sided pain and loss of motor control, for example in stroke patients with hemiparesis. In 1999 Ramachandran and Eric Altschuler expanded the mirror technique from amputees to improving the muscle control of stroke ...
A phantom limb is the sensation that an amputated or missing limb is still attached. It is a chronic condition which is often resistant to treatment. [1] When the cut ends of sensory fibres are stimulated during thigh movements, the patient feels as if the sensation is arising from the non-existent limb.
Gender, side of limb loss, and etiology of amputation have not been shown to affect the onset of phantom limb pain. [2] One investigation of lower limb amputation observed that as stump length decreased, and therefore length of the phantom limb increased, there was a greater incidence of moderate and severe phantom pain.

Targeted reinnervation has an efferent and an afferent component. Targeted muscle reinnervation is a method by which a spare muscle (the target muscle) of an amputated patient is denervated (its original nerves cut and/or de-activated), then reinnervated with residual nerves of the amputated limb.

New research shows that some ants perform limb amputations on injured comrades to improve their survival chances. The behavior was documented in Florida carpenter ants - scientific name Camponotus ...
The study found a strong connection between motor and somatosensory cortical remapping after amputation and phantom limb pain. The study assumed that somatosensory cortex reorganization can affect plasticity in the motor system because stimulation of the somatosensory cortex prompts long term potentiation in the motor cortex.
Amputation is the removal of a limb by trauma, medical illness, or surgery.As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene.
