HemiparesisHemiparesis, also called unilateral paresis, is the weakness of one entire side of the body (hemi- meaning 'half'). Hemiplegia, in its most severe form, is the complete paralysis of one entire side of the body. Either hemiparesis or hemiplegia can result from a variety of medical causes, including congenital conditions, blunt trauma, tumors, traumatic brain injury, and stroke.
OphthalmoparesisOphthalmoparesis refers to weakness (-paresis) or paralysis (-plegia) of one or more extraocular muscles which are responsible for eye movements. It is a physical finding in certain neurologic, ophthalmologic, and endocrine disease. Internal ophthalmoplegia means involvement limited to the pupillary sphincter and ciliary muscle. External ophthalmoplegia refers to involvement of only the extraocular muscles. Complete ophthalmoplegia indicates involvement of both.
Vocal cord paresisVocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
GastroparesisGastroparesis (gastro- from Ancient Greek – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period. Stomach contents thus exit more slowly into the duodenum of the digestive tract, a medical sign called delayed gastric emptying.
StomachThe stomach is a muscular, hollow organ in the upper gastrointestinal tract of humans and many other animals, including several invertebrates. The Ancient Greek name for the stomach is gaster which is used as gastric in medical terms related to the stomach. The stomach has a dilated structure and functions as a vital organ in the digestive system.
ParalysisParalysis (pl.: paralyses; also known as plegia) is a loss of motor function in one or more muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis.
Multiple sclerosisMultiple sclerosis (MS) is an autoimmune disease where the immune system attacks myelin, the insulating cover of nerve cells in the human body, causing damage to one's own central nervous system. It is a type of demyelinating disease, where the nervous system's ability to transmit signals is damaged. Symptoms can be physical, mental, or both, including double vision, vision loss, eye pain, muscle weakness, loss of sensation and coordination.
TriparesisTriparesis is a medical condition, similar to triplegia, but the major difference between the two is primarily that triplegia is total loss of function in three limbs, and triparesis denotes weakening of three limbs.
ParaplegiaParaplegia, or paraparesis, is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek (παραπληγίη) "half-stricken". It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal. The area of the spinal canal that is affected in paraplegia is either the thoracic, lumbar, or sacral regions.
MonoplegiaMonoplegia is paralysis of a single limb, usually an arm. Common symptoms associated with monoplegic patients are weakness, numbness, and pain in the affected limb. Monoplegia is a type of paralysis that falls under hemiplegia. While hemiplegia is paralysis of half of the body, monoplegia is localized to a single limb or to a specific region of the body.
TetraplegiaTetraplegia, also known as quadriplegia, is defined as the dysfunction or loss of motor or sensory function in all four limbs, typically caused by damage to the cervical area of the spinal cord. A loss of motor function can present as either weakness or paralysis leading to partial or total loss of function in the arms, legs, trunk, and pelvis (paraplegia is similar but affects the thoracic, lumbar, and sacral segments of the spinal cord, and arm function is retained).
