The triceps is easily stimulated by placing an active electrode over its motor point and the indifferent over the tendon at the elbow. As this is a fairly large muscle, it is sometimes useful to use larger electrodes, 50mm x 50mm for example, which may produce a more effective movement with greater comfort. Patient Key Points. A motor unit, the functional unit of muscle contraction, is a single motor nerve and the associated muscle fibers that are innervated upon stimulation from the nerve. A collection of motor units is referred to as a motor pool

Before entering the trial, all patients had undergone without improvement eight weeks of the Clinic's standard therapy regimen of physiotherapy, remedial exercises, and occupational therapy. The 29 study subjects and 27 control patients then continued with this regimen, but the study subjects also received needling at muscle. motor point; the indifferent electrode is placed ei-ther on fascia or a tendinous insertion (monopolar) or near the active electrode (bipolar). Bipolar stim-ulation creates a more localized electrical field, which may result in greater selectivity of muscles.11 The muscles may also start to spontaneously twitch. These twitches (fasciculations) can be seen and felt below the surface of the skin. When the lower motor neurons cannot receive signals from the upper motor neurons, it can cause muscle stiffness (spasticity) and overactive reflexes. This can make voluntary movements slow and difficult

Key Points. Motor units contain muscle fibers of all the same type; these may be many muscle fibers (as in the case of quadriceps) or a few muscle fibers (as in the case of the muscles that control eye movement) This study aimed to bring the trapezius muscle knowledge of the locations where the accessory nerve branches enter the muscle belly to reach the motor endplates and find myofascial trigger points (MTrPs).

A motor point is where the motor nerve enters the muscle. These motor nerves carry signals to the muscle that tell the muscle when to contract. When a muscle is damaged, these impulses don't fire correctly and a muscle can remain in a shortened or overstretched state. Once the trigger point — or lesion — in a muscle is released, it is. Motor point acupuncture relieves common muscular injuries quickly and effectively. It is great for treating chronic tight muscle and stubborn sports injuries as well Decisions are sent via motor pathways (efferent transmission) to muscles and joints for execution. The motor neurons are involved directly in conducting the signals from the CNS to activate muscle movement. 5.2.3 Trainable vs. Non-trainable The performance capacity of muscle is determined by several trainable and non-trainable factors Trigger points are specific, hyper-irritable and hypersensitive areas in muscle that can suffer from decreased circulation, increased contraction and spasm, and a build up of toxins and waste.Lack of circulation creates a high level of toxins and increased nerve sensitivity that can range from a low ache to a sharp pain For motor point blocks, a nerve stimulator with a surface electrode is needed to localise the motor points on the muscles. In the present study, we highlight the importance of management of spasticity in adults with a combination of botulinum toxin and phenol nerve /motor point blocks.
