Compression SyndromesAlthough peripheral nerves are fairly robust and capable of withstanding a heftyamount of distortion, under certain circumstances even a relatively small amountof pressure may trigger a cascade of immune-inflammatory responses leading toperipheral neuropathy. Certain neural parts are less protected and morevulnerable to compression or pressure injury; for example, at nerve roots andwhere a nerve travels through confined spaces such as structured tunnels(Coppieters & Nee 2012, Schmid et al. 2013).Additionally, peripheral nerves can become entrapped in dense, fibrosed tissueor compressed by dense, fibrosed neurofascia. Peripheral neuropathies may existwhere there is altered nerve conduction in the absence of severe enoughcompression to be graded as neuropraxia. Sunderland (1978) referred to suchpresentations as irritative lesion. This suggests that a nerve irritated at a lowlevelstate, something other than observable squish or fullrage inflammation, canbe the source of neuropathic pain. Pathophysiological scars may constitute suchirritative lesions.

Pathophysiological ConsiderationCompression of type C nociceptors can contribute to the pain associatedwith entrapment syndromes (Hammer 1998). Pain can be local or referred.
