Neuropathic pain is very challenging to manage because of the heterogeneity of its aetiologies, symptoms and underlying mechanisms. Most invertebrates have a neurogenic heart, while some invertebrates such as molluscs have a myogenic heart. It's not that the glutes turned off completely, but instead ' gluteal amnesia ' means the brain is diminishing neural drive and inhibiting the glute muscles from firing appropriately due to pain (a process called arthrogenic neuromuscular inhibition). [4] Therefore, criteria upon which clinicians may base their decisions for appropriate classifications have been established through an expert consensus-derived list of clinical indicators.

Post-paralytic contracture of facial muscles develops after flaccid paralysis of the muscles innervated by the facial nerve (neuropathy of the facial nerve of different etiology), but differs from other post-paralytic contractures (in the extremities) in the possibility of hyperkinesis development in the same zone ("post-paralytic facial hemispasm").
