A phantom limb is the sensation that an amputated or missing limb is still attached. It is a chronic condition that 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.
It allows for illusions of movement and touch in a phantom limb by inducing somatosensory and motor pathway coupling between the phantom and real limb. [23] Many patients experience pain as a result of a clenched phantom limb, and because phantom limbs are not under voluntary control, unclenching becomes impossible. [37]
An occupational therapy assistant using mirror therapy to address phantom pain. Mirror therapy (MT) or mirror visual feedback (MVF) is a therapy for pain or disability that affects one side of the patient more than the other side. It was invented by Vilayanur S. Ramachandran to treat post-amputation patients who had phantom limb pain (PLP ...

Ramachandran thought that phantom pain might be caused by the mismatch between different parts of an amputee's nervous systems: the visual system says the limb is missing, but the somatosensory system (processing body sensations such as touch and limb position) says the limb is still there. The so-called mirror box was a simple apparatus that ...

[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 ...
Body transfer illusion has been used in order to treat the experience of phantom limb pain by giving visual feedback of the missing limb. The mirror box gives visual feedback that can allow a person using it the opportunity to "see" the missing hand, and to manipulate the hand in an attempt to relieve pain or discomfort.
