|
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. |

Single
Fiber EMG (SFEMG) |
|
Single Fiber EMG can be used to estimate the density of
fibers belonging to a single motor unit. These fiber density
measurements are valuable in identifying reorganization of
the motor unit in neurogenic conditions and in certain
primary myopathies. |
|
|
|
|
Single
Fiber Jitter (SFJ) |
|
Single Fiber Jitter measurement is a technique used for
assessing transmission at the motor end plate. Measurements
can be made manually or with an automated analysis package
providing a sensitive technique for detecting abnormalities
of neuromuscular transmission at an early stage.

|
|
|
|
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. |
