H Reflex
|
The H Reflex results from stimulation of sensory fibers with the resulting afferent discharge causing an excitatory potential in the motor neurone pool, following a synaptic delay. Exceeding the potential threshold for a particular motor neurone generates an action potential and the resulting afferent discharge will cause the muscle fibers innervated by that neurone to be activated.

Motor Unit Action Potentials (MUAPs)
|
Measurements of various parameters of MUAPs can provide valuable data for differential diagnosis. MUAP measurements can be made manually or with an automated analysis package for recognizing and averaging potentials from particular motor units. In general, myopathies lead to a decrease in duration and amplitude of MUAPs, whereas neuropathies cause an increase in duration and amplitude.

F Wave
|
The F Response results from a centrifugal volley in an alpha motor neurone, following antidromic excitation of the nerve cell body in the ventral horn of the spinal cord. Clinical applications of F Response are conditions such as entrapment neuropathies and root compression syndrome and estimation of motor neurone excitation.

Nerve Block Therapy
|
Nerve Block therapy using Botulinum toxin offers potential as a powerful and versatile tool in the treatment of a wide variety of disorders characterised by muscle hyperactivity. The drug is injected directly into the muscles surrounding the nerve. Precise positioning of the injection is essential and is usually guided by a simultaneous EMG.
