involuntary muscle- a muscle that contracts without conscious control and found in walls of internal organs such as stomach and intestine and bladder and blood vessels (excluding the heart) smooth muscle muscle,musculus- one of the contractile organs of the body ...
Dystonias may be caused by abnormally functioning neurotransmitter chemicals within part of the brain called the basal ganglia. These chemicals (serotonin, dopamine, acetylcholine, and GABA) are required to properly send messages between brain cells that begin muscle contraction. Dystonia symptoms may ...

myodystonia: disorder of muscle tone. myoedema: edema, muscle swelling. (archaic) myofascitis: inflammation of muscle and its fascia, particularly of fascial insertion of muscle into bone. myofibroma: muscular and fibrous tumor; fibroma containing muscular elements. myofibrosis: replacement of muscle...
Ten cervical dystonia (CD) patients, with involuntary head rotation to one side and contralateral sternocleidomastoid muscle (SCM) hypertrophy, were investigated with transcranial magnetic stimulation, and the results were compared to those of 10 healthy subjects. Monopolar needle electrodes with isolated ...
Fig. 10.5 shows masseter reflex recordings at different stimulation intensities. Sign in to download hi-res image Fig. 10.5. Panels A and B illustrate several trials of intraoperative masseter responses elicited by single stimuli of increasing intensity at a repetition rate of 0.7 Hz in two ...
stimulation in the spinalized frog, the endpoint forces were the vector summation of each stimulated site. Capaday and van Vreeswijk demonstrated a mechanism in which the motor output is a linear summation without being affected by the presence of nonlinearity (intracortical and intraspinal ...
Temporal summation of pain from mechanical stimulation of muscle tissue in normal controls and subjects with fibromyalgia syndrome Individuals diagnosed with fibromyalgia syndrome (FMS) report chronic pain that is frequently worsened by physical activity and improved by rest. Palpation... R Staud,RC Cann...
Dystonia is defined as “a movement disorder in which involuntary sustained or intermittent muscle contractions cause twisting and repetitive movements, abnormal postures, or both.”8When dystonic postures are such that they are present at rest and do not relax upon attempts at passive movement, they...
Furthermore, product launches in the region are also expected to boost market growth. For instance, in November 2023, NeuroTrigger announced that its non-invasive muscle stimulation system (NTB) had been granted 510(k) clearance by the US Food and Drug Administration (FDA) for the prevention ...
