  2. Spasticity - Wikipedia

    en.wikipedia.org/wiki/Spasticity

    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 ...

  3. Hypertonia - Wikipedia

    en.wikipedia.org/wiki/Hypertonia

    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 ...

  4. Muscle tone - Wikipedia

    en.wikipedia.org/wiki/Muscle_tone

    Hypertonia can present clinically as either spasticity or rigidity. While spasticity is velocity-dependent resistance to passive stretch (e.g., passively moving an elbow quickly will elicit increased muscle tone, but passively moving elbow slowly may not elicit increased muscle tone), rigidity is velocity-independent resistance to passive ...

  5. Paratonia - Wikipedia

    en.wikipedia.org/wiki/Paratonia

    Spasticity also is velocity-dependent, [14] but, differently from oppositional paratonia, if repeatedly elicited decreases instead of increasing. [15] Conversely, parkinsonian rigidity is independent from movement velocity and probably also from movement repetition.

  6. Hypokinesia - Wikipedia

    en.wikipedia.org/wiki/Hypokinesia

    Leadpipe rigidity is sustained resistance to passive movement throughout the whole range of motion, with no fluctuations. Cogwheel rigidity is jerky resistance to passive movement as muscles tense and relax. Spasticity, a special form of rigidity, is present only at the start of passive movement. It is rate-dependent and only elicited upon a ...

    en.wikipedia.org/wiki/Extrapyramidal_symptoms

    They include movement dysfunction such as dystonia (continuous spasms and muscle contractions), akathisia (may manifest as motor restlessness), [1] parkinsonism characteristic symptoms such as rigidity, bradykinesia (slowness of movement), tremor, and tardive dyskinesia (irregular, jerky movements). [2]

  9. Upper motor neuron lesion - Wikipedia

    en.wikipedia.org/wiki/Upper_motor_neuron_lesion

    Changes in muscle performance can be broadly described as the upper motor neuron syndrome. These changes vary depending on the site and the extent of the lesion, and may include: Muscle weakness. [2] known as 'pyramidal weakness' Sloth sign. Decreased control of active movement, particularly slowness; Spasticity, a velocity-dependent change in ...
