Of medications was conducted against PLP. The literature was sourced from Pubmed, Embase and Cochrane central register ofĬontrolled trials (CENTRAL) up to February 2017. The effectiveness of both single pharmacological therapy and drug combination A range of pharmacological interventionsĮxist yet little is known about them in respect to PLP. PLP can be severe and difficult to treat.

14 The neuromatrix theory of pain states that the perception of painful stimuliĭoes not result from the brain’s passive registration of tissue trauma, but from itsĪctive generation of subjective experiences through a network of neurones known as This leads to excessiveĪctivity in the neuromatrix due to lack of signals from the limb. Once the limb has beenĪmputated, the brain still has the old geography wired in. 13 The final factor is cortical reorganization. The increased neuronal activity leads to a central sensitization or ‘Wind-up phenomenon’. 12 As a result, even light touch can cause a lot of discomfort. Inter-neurones that normally receive input from nociceptors. This means that the ‘wrong connections’Īre made and sensory neurones responsible for touch might connect with the In lamina II instead of laminae III or IV. This sprouting allows the sensory axons to terminate 12 This lowered threshold potential further increases the rate of neuroneįollowing transection of peripheral axons sprouting occurs of the ventral terminals There is aĬoncurrent alteration in the sodium channel membrane potential.

Phantom limb pain (PLP) is a complex condition resulting in pain in the missing limb.
