Strength-duration curve: a measure for assessing sensory deficit in peripheral neuropathy.

Strength-duration curve: a measure for assessing sensory deficit in peripheral neuropathy.

By using an isolated constant current stimulator producing true square-wave pulses, sensory strength-duration curves were obtained at various sites by percutaneous electrical stimulation. Strength-duration curves derived from normal groups were compared to those of patients with peripheral neuropathy. Stimulus strength at sensory threshold was shown to be a reproducible measure of sensory defic...

Pharmacoethnicity in Paclitaxel-Induced Sensory Peripheral Neuropathy.

PURPOSE Paclitaxel is used worldwide in the treatment of breast, lung, ovarian, and other cancers. Sensory peripheral neuropathy is an associated adverse effect that cannot be predicted, prevented, or mitigated. To better understand the contribution of germline genetic variation to paclitaxel-induced peripheral neuropathy, we undertook an integrative approach that combines genome-wide associati...

Assessing diabetic peripheral neuropathy in primary care

Strength-duration properties of human peripheral nerve.

The strength-duration time constant (tau SD) is a property of nodal membrane and, while it depends on a number of factors, its measurement may shed light on axonal properties when taken in conjunction with measurements of axonal excitability. For example, tau SD increases with demyelination as the exposed membrane is enlarged by inclusion of paranodal and internodal membrane, it decreases with ...

Statin use and peripheral sensory neuropathy: a pilot study

Background Peripheral sensory neuropathy is a neurological deficit resulting in decreased detection of sensation through the peripheral nervous system. Statins are a widely used medication and there has been some debate of association with their use and the presence of peripheral sensory neuropathy. This pilot study aimed to test the sensory perception of participants with long term statin use ...
