Paralyse
Paralysis (: 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. The word "paralysis" derives from the Greek παράλυσις, meaning "disabling of the nerves" from παρά (''para'') meaning "beside, by" and λύσις (''lysis'') meaning "making loose". A paralysis accompanied by involuntary tremors is usually called "palsy". Causes Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis and Guillain–Barré syndrome. Incidents that can cause such damage include slip and fall accidents, mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palsy
Palsy is a medical term which refers to various types of paralysisDan Agin, ''More Than Genes: What Science Can Tell Us About Toxic Chemicals, Development, and the Risk to Our Children'' (2009), p. 172. or paresis, often accompanied by weakness and the loss of feeling and uncontrolled body movements such as shaking. The word originates from the Anglo-Norman ''paralisie'', ''parleisie'' ''et al.'', from the accusative form of Latin ''paralysis'', from Ancient Greek παράλυσις (''parálusis''), from παραλύειν (''paralúein'', "to disable on one side"), from παρά (''pará'', "beside") + λύειν (''lúein'', "loosen"). The word is longstanding in the English language, having appeared in the play '' Grim the Collier of Croydon'', reported to have been written as early as 1599: In some editions, the Bible passage of Luke 5:18 is translated to refer to "a man which was taken with a palsy". More modern editions simply refer to a man who is paralysed. Although th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poliomyelitis
Poliomyelitis ( ), commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 75% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases.. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to what the person had during the initial infection. Polio occurs naturally only in humans. It is highly infectious, and is spread from person to person either through fecal–oral transmission (e.g. poor hygiene, or by ingestion of food or water contaminated by human feces), or via the oral–oral route. Those who are infected may spread the disease for up to six weeks even if no symptoms are present. The disease may be diagnosed by ...

Guillain–Barré Syndrome
Guillain–Barré syndrome (GBS) is a rapid-onset Paralysis, muscle weakness caused by the immune system damaging the peripheral nervous system. Typically, both sides of the body are involved, and the initial symptoms are changes in sensation or pain often in the back along with muscle weakness, beginning in the feet and hands, often spreading to the arms and upper body. The symptoms may develop over hours to a few weeks. During the acute phase, the disorder can be life-threatening, with about 15% of people developing respiratory system, respiratory muscle weakness requiring mechanical ventilation. Some are affected by dysautonomia, changes in the function of the autonomic nervous system, which can lead to dangerous abnormalities in heart rate and blood pressure. Although the cause is unknown, the underlying mechanism involves an autoimmune disorder in which the body's immune system mistakenly attacks the peripheral nerves and damages their myelin insulation. Sometimes this im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerebral Palsy
Cerebral palsy (CP) is a group of movement disorders that appear in early childhood. Signs and symptoms vary among people and over time, but include poor coordination, spasticity, stiff muscles, Paresis, weak muscles, and tremors. There may be problems with sense, sensation, visual perception, vision, hearing, and speech. Often, babies with cerebral palsy do not roll over, sit, crawl or walk as early as other children. Other symptoms may include seizures and problems with cognition, thinking or reasoning. While symptoms may get more noticeable over the first years of life, underlying problems do not worsen over time. Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. Most often, the problems occur during pregnancy, but may occur during childbirth or shortly afterwards. Often, the cause is unknown. Risk factors include preterm birth, being a twin, certain infections or exposure to methylmercury duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sleep Paralysis
Sleep paralysis is a state, during waking up or falling asleep, in which a person is conscious but in a complete state of full-body paralysis. During an episode, the person may hallucinate (hear, feel, or see things that are not there), which often results in fear. Episodes generally last no more than a few minutes. It can reoccur multiple times or occur as a single episode. The condition may occur in those who are otherwise healthy or those with narcolepsy, or it may run in families as a result of specific genetic changes. The condition can be triggered by sleep deprivation, psychological stress, or abnormal sleep cycles. The underlying mechanism is believed to involve a dysfunction in REM sleep. Diagnosis is based on a person's description. Other conditions that can present similarly include narcolepsy, atonic seizure, and hypokalemic periodic paralysis. Treatment options for sleep paralysis have been poorly studied. It is recommended that people be reassured that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
REM Sleep
Rapid eye movement sleep (REM sleep or REMS) is a unique phase of sleep in mammals (including humans) and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly. The core body and brain temperatures increase during REM sleep and skin temperature decreases to lowest values. The REM phase is also known as paradoxical sleep (PS) and sometimes desynchronized sleep or dreamy sleep, because of physiological similarities to waking states including rapid, low-voltage desynchronized brain waves. Electrical and chemical activity regulating this phase seem to originate in the brain stem, and is characterized most notably by an abundance of the neurotransmitter acetylcholine, combined with a nearly complete absence of monoamine neurotransmitters histamine, serotonin and norepinephrine. Experiences of REM sleep are not transferred to permanent memory due to absence of norepinephrine. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Injury
Sports injuries occur during participation in sports or exercise in general. Globally, around 40% of individuals engage in some form of regular exercise or organized sports, with upwards of 60% of US high school students participating in one or more sports. Sports injuries account for 15 - 20% of annual acute care visits with an incidence of 1.79 - 6.36 injuries per 1,000 hours of participation. Sports injuries can be broken down into the types of injuries, risk factors and prevention and the overall impact that injuries have on athletes. Types of sport injury The type of sports injury suffered varies greatly based on gender, age and sport. Nonetheless, those with the highest prevalence remain contusions, fractures and sprains, followed closely by wounds and overuse injuries. Also common, the possible severity of head and neck injuries are important to consider. It is also paramount to place emphasis on the specific injuries that are most commonly encountered by sports medicine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunshot Wound
A gunshot wound (GSW) is a penetrating injury caused by a projectile (e.g. a bullet) shot from a gun (typically a firearm). Damage may include bleeding, bone fractures, organ damage, wound infection, and loss of the ability to move part of the body. Damage depends on the part of the body hit, the path the bullet follows through (or into) the body, and the type and speed of the bullet. In severe cases, although not uncommon, the injury is fatal. Long-term complications can include bowel obstruction, failure to thrive, neurogenic bladder and paralysis, recurrent cardiorespiratory distress and pneumothorax, hypoxic brain injury leading to early dementia, amputations, chronic pain and pain with light touch (hyperalgesia), deep venous thrombosis with pulmonary embolus, limb swelling and debility, and lead poisoning. Factors that determine rates of gun violence vary by country. These factors may include the illegal drug trade, easy access to firearms, substance misuse i ...

Assault
In the terminology of law, an assault is the act of causing physical harm or consent, unwanted physical contact to another person, or, in some legal definitions, the threat or attempt to do so. It is both a crime and a tort and, therefore, may result in criminal prosecution, civil liability, or both. Additionally, assault is a criminal act in which a person intentionally causes fear of physical harm or offensive contact to another person. Assault can be committed with or without a weapon and can range from physical violence to threats of violence. Assault is frequently referred to as an attempt to commit battery (crime), battery, which is the deliberate use of physical Force (law), force against another person. The deliberate inflicting of fear, apprehension, or terror is another definition of assault that can be found in several legal systems. Depending on the severity of the offense, assault may result in a fine, imprisonment, or even death. Generally, the common law definitio ...

Motor Vehicle Accidents
A traffic collision, also known as a motor vehicle collision, or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and property damage as well as financial costs to both society and the individuals involved. Road transport is statistically the most dangerous situation people deal with on a daily basis, but casualty figures from such incidents attract less media attention than other, less frequent types of tragedy. The commonly used term car accident is increasingly falling out of favor with many government departments and organizations: the Associated Press style guide recommends caution before using the term and the National Union of Journalists advises against it in their Road Collision Reporting Guidelines. Some collisions are intentional vehicle-ramming attacks, staged crashes, vehicular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slip And Fall
A slip and fall injury, also known as a trip and fall, is a premises liability claim, a type of personal injury claim or case based on a person slipping (or tripping) on the premises of another and, as a result, suffering injury. It is a tort. A person who is injured by falling may be entitled to monetary compensation for the injury from the owner or person in possession of the premises where the injury occurred. Liability for slip or trip and fall injuries may arise based upon a defendant's ownership of the premises where the injury occurred, their control of the premises, or both. For example, a store may be liable for a slip-and-fall injury that occurs inside of its premises, even though it rents those premises, because it has exclusive control of the interior of the rented property. The owner of the premises (the store's landlord) may have sole or shared liability for an injury that occurs outside of the store's exclusive premises, such as the injury from a fall on the sidew ...

Multiple Sclerosis
Multiple sclerosis (MS) is an autoimmune disease resulting in damage to myelinthe insulating covers of nerve cellsin the brain and spinal cord. As a demyelinating disease, MS disrupts the nervous system's ability to Action potential, transmit signals, resulting in a range of signs and symptoms, including physical, cognitive disability, mental, and sometimes psychiatric problems. Symptoms include double vision, vision loss, eye pain, muscle weakness, and loss of Sensation (psychology), sensation or coordination. MS takes several forms, with new symptoms either occurring in isolated attacks (relapsing forms) or building up over time (progressive forms). In relapsing forms of MS, symptoms may disappear completely between attacks, although some permanent neurological problems often remain, especially as the disease advances. In progressive forms of MS, bodily function slowly deteriorates once symptoms manifest and will steadily worsen if left untreated. While its cause is unclear, ...
