Motor points are elecrophysilogically defined, as the point with the highest excitability of the muscle or the point on the skin where muscle contraction can be observed by the least electrical stimulation or the point on the muscle where muscle contractions can be caused by the minimum intensity and short duration ...Apr 30, 2012
What is the function of the a motor point?
Apr 07, 2020 · Muscle motor point, also known as motor entry point, represents the location where the motor branch of a nerve enters the muscle belly. It can be non-invasively identified by NMES as the skin area above the muscle in which an electrical pulse evokes a visible muscle twitch with the least injected current.
How are motor point locations measured?
Medical Definition of motor point. : a small area on a muscle at which a minimal amount of electrical stimulation will cause the muscle to contract.
Aug 10, 2021 · Motor Point is a point at which a motor nerve enters a muscle. Motor Point is located where the motor nerve enters the muscle. It is where the muscle is most electrically excitable. Some of the motor points on the anterior aspect of right arm & forearm muscles.
What is the motor point of a muscle?
Muscle motor point, also known as motor entry point, represents the location where the motor branch of a nerve enters the muscle belly. It can be non-invasively identified by NMES as the skin area above the muscle in which an electrical pulse evokes a visible muscle twitch with the least injected current.Jul 28, 2011
How do you identify a motor point?
It consists in muscle surface mapping by using a stimulation pen-electrode and it is aimed at identifying the skin area above the muscle where the motor threshold is the lowest for a given electrical input, that is the skin area most responsive to electrical stimulation.Feb 25, 2014
Why are motor points important?
Recent evidence has highlighted the crucial importance of stimulating over the muscle motor points to improve the effectiveness of neuromuscular electrical stimulation.Feb 25, 2014
What is a motor point quizlet?
An area of greatest excitability on the skin surface in which a small amount of current generates a muscle response. In innervated muscle, the motor point is located at or near where the motor nerve enters the muscle, usually over the muscle belly.
Where are motor points located?
The motor point is usually located at the center of the muscle mass where the motor nerve enters the muscle.Jan 20, 2021
What is motorpoint stimulation?
CLINICALLY; A motor point is a specific skin area where the targeted muscle is best stimulated with the smallest amount of current amplitude and the shortest pulse duration ANATOMICALLY; This same motor point is defined as the surface entry point of a bundle of motor nerve fibers into a fasicle of muscle fibers.
What is facial motor point?
Motor points are located at the most electrically excitable part of the muscle where the motor nerve bundle is attached. More specifically, a motor point is defined as "the skin region where an innervated muscle is most accessible to percutaneous electrical excitation at the lowest intensity.
What is a motor unit?
The combination of an individual motor neuron and all of the muscle fibers that it innervates is called a motor unit. The number of fibers innervated by a motor unit is called its innervation ratio.
What is the meaning of electrical stimulation?
Definition. Electrical stimulation (e-stim) is the use of a device to send gentle electrical pulses through the skin. Two common devices are: Electrical muscle stimulation (EMS) to help repair muscles. Transcutaneous electrical nerve stimulation (TENS) to help with pain.
How to find motor points?
Starting in the early 1990s, the author used the EMS-2A to begin the process of finding the precise motor point locations on the skin, so that acupuncturists would be able to accurately stimulate these points. The process of testing the points went much like this: 1 Once the area of the skin was identified as the probable location of the motor point, the 8 mm circular head from the electrical stimulator was placed on the skin. 2 In order to complete the stimulation current loop (monopolar stimulation), a reference electrode was placed over the antagonist muscle unit before the electrical current was initiated. 3 A small electrical current was applied from the electrical stimulator to different locations on the skin where the motor point was suspected to lie until it evoked a muscle twitch. 4 The twitch response was determined by visual inspection and manual palpation of the muscle and its proximal or distal tendon. When the twitch response was identified, the stimulation current was decreased to a value that still elicited a small response of the muscle in order to further refine the location of the muscle motor point. 5 Once the motor point was found and recorded, the author tested the same point location on at least 5 other people to determine the reliability of the location.
Where is the MEP located?
There is a high likelihood that the MEP can be found in the central aspect of the muscle, which is the location that provides the best advantage for neuro-mechanical efficiency to affect the entire muscle. 15 When examining muscle motor points in cadaver dissection, there is usually one primary MEP in each muscle.

The motor point has been described as the zone of innervation, which in turn can be defined as either where the motor nerve first pierces the muscle belly, also known as the motor nerve entry point (MEP), or where the terminal end of the motor nerve is located at the motor-end plate (also known as the intramuscular motor point). 5-7 The motor point has also been defined as the …

Jul 10, 2016 · A motor point is a point on the skin at which electrical stimulation causes contraction of a muscle. > (From http://www.ncbi.nlm.nih.gov) When the electrode is over the motor point (MP), the motor nerve is stimulated. The electrical impulse mimics the action potential coming from the central nervous system and causes the muscle to contract.
