Neuropathic tremor is assumed to be present if a patient develops tremor together with a peripheral neuropathy in the absence of any other neurological disorder. Certain peripheral neuropathies tend to produce tremor more often than others, particularly demyelinating polyneuropathies. These tremors are usually postural and kinetic with frequencies of 3–6 Hz in arm and hand muscles. The frequency in hand muscles can be lower than in proximal arm muscles in patients with gammopathies. Fortunately, most of these patients have only a slight tremor. No specific drugs are available for this disorder, but in most cases, it is not severe enough to require pharmacological treatment.
