Peripheral neuropathy is a term used to describe conditions in which there is weakness or injury to the muscles and sensory organs because of damage to the nerves that supply them – the peripheral nervous system.
A tremor may appear in a patient with peripheral neuropathy – neuropathic tremor (NT). It may be the presenting feature in polyneuropathies, or in other diseases which affect the peripheral nerves. In these cases, the tremor occurs because of exaggeration of the physiological or normal tremor as a result of weakness to a minimal degree.
The nerves to the peripheral muscles and sensory organs may be damaged by disease or injury, higher levels of nervous dysfunction, or systemic disease. NT may be seen in certain areas only, typically the upper limb, or over the whole body.
