Apa Itu Motor Point?

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.

How do you find the motor point of a muscle?

To locate your own motor point more accurately, you can move the positive electrode slightly (red cable) and watch where the muscle response is the best (strongest twitch of the same intensity). The motor point pen is an accessory that is sold separately in order to find the motor point.

What is facial motor point?

Motor Point is located where the motor nerve enters the muscle. It is where the muscle is most electrically excitable. MOTOR POINT OF FACIAL MUSCLES. Some of the important facial muscles stimulate during facial nerve palsy. Frontalis.

Why do we use motor points?

Recent evidence has highlighted the crucial importance of stimulating over the muscle motor points to improve the effectiveness of neuromuscular electrical stimulation. If routinely applied, we expect this procedure to improve both stimulation effectiveness and patient adherence to the treatment.

Which current is used in motor point?

A galvanic current uses mild electric currents that consist of positive and negative ions to stimulate the local muscles. The outcome of a galvanic current is maintaining the muscle physiology. The faradic current has a frequency of 50 Hz. It produces tetanic muscle contraction.

Why does electrical stimulation of a motor point lead to muscle contraction?

When the active electrode precisely overlies the motor point (MP), less current is required to excite the motor axons and thus to elicit the muscle contraction.

What is a motor point in a muscle?

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

What do large motor units contain?

Larger motor units are typically composed of faster muscle fibers that generate higher forces. The central nervous system has two distinct ways of controlling the force produced by a muscle through motor unit recruitment: spatial recruitment and temporal recruitment.

What does neuromuscular electrical stimulation do?

Neuromuscular Electrical Stimulation or NMES uses a device that sends electrical impulses to nerves. This input causes muscles to contract. The electrical stimulation can increase strength and range of motion, and offset the effects of disuse.

Which current is used in facial palsy?

Galvanic currents are used primarily for facial muscles. A galvanic current uses mild electric currents that consist of positive and negative ions to stimulate the local muscles. The outcome of a galvanic current is maintaining the muscle physiology. The faradic current has a frequency of 50 Hz.

Where are the facial muscles?

The facial muscles are striated muscles that attach to the bones of the skull to perform important functions for daily life, including mastication and facial expressions. These muscles are located medially to the ears, superior to the mandible, and inferior to the coronal suture of the skull.

What is nerve point stimulation?

Neurostimulation is the purposeful modulation of the nervous system’s activity using invasive (e.g. microelectrodes) or non-invasive means (e.g. transcranial magnetic stimulation or transcranial electric stimulation, tES, such as tDCS or transcranial alternating current stimulation, tACS).

How are motor nerves stimulated?

Motor nerves can be activated through electrodes placed on the surface of the skin, on the surface of the muscle, in the muscle, on the motor nerve or in the motor nerve.

Why are motor points important in athletic training?

8,19,20 A motor point (MP) is the most superficial motor nerve that can be stimulated with the smallest amount of electrical current. Applying NMES with electrodes over a MP helps decrease patient discomfort and can improve quadriceps torque when comparing to traditional electrode placement.
