In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. [1] [2] It helps to maintain posture and declines during REM sleep. [3]
Spastic hypertonia involves uncontrollable muscle spasms, stiffening or straightening out of muscles, shock-like contractions of all or part of a group of muscles, and abnormal muscle tone. It is seen in disorders such as cerebral palsy, stroke, and spinal cord injury. Rigidity is a severe state of hypertonia where muscle resistance occurs ...
The low muscle tone associated with hypotonia must not be confused with low muscle strength or the definition commonly used in bodybuilding. Neurologic muscle tone is a manifestation of periodic action potentials from motor neurons. As it is an intrinsic property of the nervous system, it cannot be changed through voluntary control, exercise ...
Myogenic tone is a state of muscle tone in living creatures that originates from the muscle itself rather than from the autonomic nervous system or from hormone processes. It may be contrasted with neurogenic tone , which is created by actions of the autonomic nervous system.
Paratonia is the inability to relax muscles during muscle tone assessment. There are two types of paratonia: oppositional and facilitatory. There are two types of paratonia: oppositional and facilitatory.
Airway tone, short for airway smooth muscle tone, is the degree of sustained contractile activation of airway smooth muscle. [1] The airways have a tone baseline, and consequently a baseline level of contraction of their smooth musculature. Airway tone is a key determinant of lung function and the presence of respiratory symptoms in obstructive ...
Spasticity can be differentiated from rigidity with the help of simple clinical examination, as rigidity is a uniform increase in the tone of agonist and antagonist muscles which is not related to the velocity at which the movement is performed passively and remains the same throughout the range of movement while spasticity is a velocity ...
Exercises can aid fat loss or stimulate muscle hypertrophy, but cannot otherwise improve tone. [1] The size of the muscle can change, as can the amount of fat covering the muscle, but the 'shape' cannot. The words "tone" and "toning" can be misleading as they suggest that spot reduction is possible, which it is not. More accurate descriptions ...
