Understanding and Treating Phantom Limb Pain
TLDR Phantom limb pain is a real affliction experienced by amputees, causing a range of pain sensations in the limb that is no longer there. Despite the large number of amputations that occur each year, the cause of phantom limb pain is still unknown, but researchers are working on finding a cure and improving functionality through targeted muscle and sensory re-innovation.
Timestamped Summary

Phantom pain is a topic that the podcast hosts are surprised they haven't covered yet, but they have discussed related topics like amputations and the mirror box.
04:57
Phantom pain is a real affliction experienced by amputees, causing a range of pain sensations in the limb that is no longer there.
10:13
Phantom limb pain was first differentiated into residual limb pain and phantom limb pain by Paré, who also identified different factors that can trigger it and different treatments, and our understanding of phantom limb pain still revolves around these concepts today.
15:17
Silas Weir Mitchell estimated that a high number of his amputee patients, around 86 out of 90, experienced phantom limb pain, which was attributed to psychological causes until the mid-20th century.
20:44
Phantom limb pain can have psychological impacts and cause abnormal movements, such as walking sideways through a doorway, and can also lead to constant discomfort and frustration, like feeling that your arm is twisted behind your back at all times.
25:36
Despite the large number of amputations that occur each year, the cause of phantom limb pain is still unknown, with theories including central nervous system issues and brain mapping, as well as the possibility of thickened nerve endings.
30:44
Phantom limb pain may be caused by the remaining nerve endings seeking connections and transmitting electricity, as well as the brain's failure to update its map of the body after amputation.
35:52
The cause of phantom limb pain is still unknown, despite previous theories about tricking the brain with a mirror box and studies on brain reconnection after amputation.
40:40
Researchers are currently working on helping people use prosthetic limbs more effectively by using targeted muscle and sensory re-innovation to connect nerves from the amputated limb to muscles and recreate the sensation of having a real limb, which can help alleviate phantom limb pain and improve functionality.
45:50
The more lifelike the feedback from a prosthetic limb is, the more it can help alleviate phantom limb pain by reconnecting nerves from the amputated limb to muscle tissue or sensory cables from the prosthetic.
50:41
Phantom limb pain can be alleviated through various treatments such as biofeedback, lifestyle changes, and physical stimulation, but it is crucial to fully understand and find a cure for this condition.
