In human sexuality, paralysis, also known as rape paralysis, [1] involuntary paralysis, [2] fright (or faint), [3] [4] or tonic immobility, [1] [3] [5] is a natural bodily survival reaction which can be automatically activated by the brain of a person who feels threatened by sexual violence. During this paralysis, one cannot move and cannot say ...
Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder.The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles and rigidity. [1]
The term cataplexy originates from the Greek κατά (kata, meaning "down"), and πλῆξις (plēxis, meaning "strike") [4] and it was first used around 1880 in German physiology literature to describe the phenomenon of tonic immobility also known as "playing possum" (in reference to the opossum's behavior of feigning death when threatened ...
It was found that subjects who received hydrotherapy treatment obtained increased FIM scores and a decreased intake of oral baclofen medication. [29] A 2009 study looked at the effect of hydrotherapy to decrease spasticity on post- stroke , hemiparetic patients with limited mobility and concluded that there was a significantly larger increase ...
Baclofen, diazepam and dantrolene remain the three most commonly used pharmacologic agents in the treatment of spastic hypertonia. Baclofen is generally the drug of choice for spinal cord types of spasticity, while sodium dantrolene is the only agent which acts directly on muscle tissue. Tizanidine is also available.
Drugs that interfere with nerve function, such as curare, can also cause paralysis. Pseudoparalysis ( pseudo- meaning "false, not genuine", from Greek ψεῦδος [ 7 ] ) is voluntary restriction or inhibition of motion because of pain, incoordination, orgasm, or other cause, and is not due to actual muscular paralysis. [ 8 ]
Paradoxical reactions to treatment are notable. Drugs which most people respond to may in other individuals worsen their symptoms. Sometimes this leads to the mistake of increasing the dose, rather than decreasing or stopping the drug. [9] Treatment of myoclonus focuses on medications that may help reduce symptoms.
It can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. Muscle atrophy leads to muscle weakness and causes disability. Disuse causes rapid muscle atrophy and often occurs during injury or illness that requires immobilization of a limb or bed rest.
