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 ...
Another central cause is that the perception of the phantom odor usually follows after the occurrence of seizures. The time span of the symptoms usually lasts a few seconds. [15] Other studies on phantosmia patients have found that the perception of the odor initiates with a sneeze, thus they avoid any nasal activity.
Dysosmia can be classified as either parosmia (also called troposmia) or phantosmia. Parosmia is a distortion in the perception of an odorant. Odorants smell different from what one remembers. Phantosmia is the perception of an odor when no odorant is present. The cause of dysosmia still remains a theory.
Upper motor neuron syndrome (UMNS) is the motor control changes that can occur in skeletal muscle after an upper motor neuron lesion. Following upper motor neuron lesions, affected muscles potentially have many features of altered performance including: weakness (decreased ability for the muscle to generate force)
Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities. Discoordination can also occur internally especially with the respiratory muscles and it often goes unrecognized. [3] Dyskinesia is a symptom of several medical disorders that are distinguished by their underlying ...
Dystonia is a movement disorder in which involuntarily sustained or intermittent muscle contractions cause twisting or repetitive movements, abnormal postures, or both. Such abnormal postures include foot inversion, wrist ulnar deviation, or lordotic trunk twisting. [ 4 ]
Lav Diaz’s “Phantosmia,” which has its world premiere at the Venice Film Festival in the out of competition section, has debuted its trailer. The film centers on Hilarion Zabala, whose ...
Extrapyramidal symptoms (also called extrapyramidal side effects) get their name because they are symptoms of disorders in the extrapyramidal system, which regulates posture and skeletal muscle tone. This is in contrast to symptoms originating from the pyramidal tracts. [citation needed]
