Microgravity also causes the heart to weaken over time, leading to deconditioning and even shrinkage.

Older people faced the risks of hospitalization all over again: infections, deconditioning, delirium, subsequent nursing home stays.

So, we hypothesized that a moderate daily dose would help mitigate muscle deconditioning in a Mars gravity analogue, too.

Emergency rooms often serve as gateways to longer stays, and the time spent in bed leads quickly to deconditioning.

Their goal was to figure out which one might be better for astronauts dealing with the "deconditioning" that happens when they're weightless.
|
|
That trip, and the astronauts' potential time spent in Martian gravity -- 38% of the surface gravity on Earth -- creates the potential for muscle atrophy and deconditioning.
|
|
The patients, meanwhile, faced additional risks of disrupted sleep, infections, physical deconditioning from time spent in bed and other hazards, while generating needlessly higher hospital bills.
|

Studies have shown that those most at-risk are over 60 and/or have preexisting health problems like diabetes, obesity, cardiac disease, lung disease or generalized deconditioning.
|
|
With a physician's O.K., they can accompany relatives on short strolls down the corridor to ward off deconditioning, and ask about curtailing wee-hour tests and readings.

"It is possible to work around conditioning and deconditioning of the brain, if there is a clear indication that certain behaviours might be counterproductive over time," he said.

The data show many interesting aspects of the autonomic nervous system's response to microgravity exposure and prolonged deconditioning, which would have been difficult to study otherwise, said Dr. Tae Chung of Johns Hopkins Medicine in Baltimore, Maryland, who leads the Johns Hopkins POTS clinic.

His argument is that the therapies evaluated in the PACE trial are based on a misguided hypothesis that CFS/ME patients suffer from "unhelpful" beliefs that they have a biological disease, and that their symptoms of fatigue are made worse by deconditioning due to inactivity.

Deconditioning is adaptation of an organism to less demanding environment, or, alternatively, the decrease of physiological adaptation to normal conditions. Decondition may result from decreased physical activity, prescribed bed rest, orthopedic casting, paralysis, aging, etc. McGraw-Hill Encyclopedia of Science and Technology A particular interest in the study of deconditioning is in aerospace medicine, to diagnose, fight, and prevent adverse effects of the conditions of space flight. Deconditioning due to decreased physical effort results in muscle loss, including heart muscles.

Intrinsic risk factors include obesity and limited ankle dorsiflexion. Extrinsic risk factors include deconditioning, hard surfaces, inadequate stretching and poor footwear.
|
|
Deconditioning due to lack of gravity or non-standard gravity action (e.g., during bed rest) results in abnormal distribution of body fluids.

This theory regards CFS as being reversible and that cognitive responses (fear of engaging in activity) and behavioural responses (avoidance of activity) are linked and interact with physiological processes to perpetuate fatigue. The aim of treatment was to change the behavioural and cognitive factors assumed to be responsible for perpetuation of the participant's symptoms and disability. Graded exercise therapy (GET) was done on the basis of deconditioning and exercise intolerance theories of chronic fatigue syndrome. These theories assume that CFS is perpetuated by reversible physiological changes of deconditioning and avoidance of activity; these changes result in the deconditioning being maintained and an increased perception of effort during exertion and increased symptoms after unaccustomed activity, leading to further inactivity.

Long-term exposure causes multiple health issues. The most significant is bone loss, some of which is permanent, but microgravity also leads to significant deconditioning of muscular and cardiovascular tissues.

Individuals with severe and long-standing sacroiliac joint dysfunction can develop muscle deconditioning and atrophy throughout the body due to limitation of activities and exercise that bring about pain in the low back.

Most hip fractures are treated surgically by implanting a prosthesis. Surgical treatment outweighs the risks of nonsurgical treatment which requires extensive bedrest. Prolonged immobilization increases risk of thromboembolism, pneumonia, deconditioning, and decubitus ulcers. Regardless, the surgery is a major stress, particularly in the elderly.

LaVey also developed his own Black Mass, which was designed as a form of deconditioning to free the participant from any inhibitions that they developed living in Christian society. He noted that in composing the Black Mass rite, he had drawn upon the work of Charles Baudelaire and Joris-Karl Huysmans.

If HG is inadequately treated, anemia, hyponatremia, Wernicke's encephalopathy, kidney failure, central pontine myelinolysis, coagulopathy, atrophy, Mallory- Weiss tears, hypoglycemia, jaundice, malnutrition, pneumomediastinum, rhabdomyolysis, deconditioning, deep vein thrombosis, pulmonary embolism, splenic avulsion, or vasospasms of cerebral arteries are possible consequences. Depression and post-traumatic stress disorder are common secondary complications of HG and emotional support can be beneficial.

The sojourn of astronauts in space elicits substantial deconditioning effects within the cardiovascular system and equally great losses of bone and muscle mass. Astronauts share these problems with the older population, and especially with the bed-ridden and the immobilised. An aspect that becomes more important, in particular in the light of the demographic development in Germany. Even the young generation is affected.

Because "Little Albert" was taken out of town, Watson did not have the time to decondition the child. This obviously has ethical implications, but Watson did put in place a method for deconditioning fears. He worked with a colleague, Mary Cover Jones, on a set of procedures aimed at eliminating the fears of another little boy, Peter. Peter seemed to fear white rats and rabbits.

Kaula stresses the language of self-sufficiency, liberation and freedom., p. 59 Socially the Kaula may be viewed as an alternative society, complete in itself, which supports the freedom of the devotee from interior mental and egotistic limitations and from exterior social and cultural preconceptions. At a social level deconditioning is realized by detaching from traditional restrictions with regard to what is considered pure and impure and through the adoption of the spiritual family of the guru.

Though these changes are usually temporary, some do have a long-term impact on human health. Short-term exposure to microgravity causes space adaptation syndrome, self-limiting nausea caused by derangement of the vestibular system. Long-term exposure causes multiple health problems, one of the most significant being loss of bone and muscle mass. Over time these deconditioning effects can impair astronauts' performance, increase their risk of injury, reduce their aerobic capacity, and slow down their cardiovascular system.

Prolonged bed rest has long been known to have deleterious physiological effects, such as muscle atrophy and other forms of deconditioning such as arterial constriction. Besides lack of physical exercise it was shown that another important factor is that the hydrostatic pressure (caused by gravity) acts anomalously, resulting in altered distribution of body fluids. In other words, when getting up, this can cause an orthostatic hypertension, potentially inducing a vasovagal response. Additionally, prolonged bed rest can lead to the formation of skin pressure ulcers.

The effects of microgravity on fluid distribution around the body (greatly exaggerated). Medical data from astronauts in low Earth orbits for long periods, dating back to the 1970s, show several adverse effects of a microgravity environment: loss of bone density, decreased muscle strength and endurance, postural instability, and reductions in aerobic capacity. Over time these deconditioning effects can impair astronauts' performance or increase their risk of injury. In a weightless environment, astronauts put almost no weight on the back muscles or leg muscles used for standing up, which causes them to weaken and get smaller.

Geriatric rehabilitation covers three areas – normal aging due to disuse and deconditioning, cardiovascular problems like vascular disease and stroke, and skeletal problems including osteoporosis and osteoarthritis conditions such as knee and hip replacements. Physical medicine physicians [physiotherapists] use rehabilitation to work toward the goal of returning the patient to a pre-injury quality of life and may use physical, occupational, and speech therapies.Geriatric Rehab With increased age, patients often face many physical and emotional changes that can affect level of physical, mental, social function and well-being. Rehabilitation maintains functional independence in the elderly.

The use of conventional nerve conduction studies is time consuming and requires specialized personnel; however, simplified electrophysiologic tests can be used as screening tools in the critically ill to confirm or exclude CIP/CIM. The peroneal nerve test is a validated, high- sensitivity, minimally invasive, non-volitional and quick diagnostic test which can accurately exclude CIP/CIM if the result is normal. Moreover, patients with disuse atrophy and muscle deconditioning have normal electrophysiological tests even if muscle strength is severely reduced Hence, these tests are important to define the cause of muscle weakness and can be helpful to refine the prognosis.

People with osteoporosis are at higher risk of falls due to poor postural control, muscle weakness, and overall deconditioning. Postural control is important to maintaining functional movements such as walking and standing. Physical therapy may be an effective way to address postural weakness that may result from vertebral fractures, which are common in people with osteoporosis. Physical therapy treatment plans for people with vertebral fractures include balance training, postural correction, trunk and lower extremity muscle strengthening exercises, and moderate-intensity aerobic physical activity.. The goal of these interventions are to regain normal spine curvatures, increase spine stability, and improve functional performance.

He would pursue this 'Paratheatrical' phase until 1978. This phase is known as the 'Paratheatrical' phase of his career because it was an attempt to transcend the separation between performer and spectator. Grotowski attempted this through the organization of communal rites and simple interactive exchanges that went on sometimes for extended periods, attempting to provoke in poor participants a deconditioning of impulse. The most widely circulated description of one of these post-theatrical events (a "beehive") is given by Andre Gregory, Grotowski's longtime friend and the American director whose work he most strongly endorsed, in My Dinner With Andre.

According to Lon Milo DuQuette, a Thelemite is anyone who bases their actions on striving to discover and accomplish their true will,DuQuette, Lon Milo, Angels, demons & gods of the new millennium, Weiser, 1997, , p. 3 when a person does their True Will, it is like an orbit, their niche in the universal order, and the universe assists them.DuQuette, Lon Milo, The Magick of Aleister Crowley, Weiser, 2003, , p. 12 In order for the individual to be able to follow their True Will, the everyday self's socially-instilled inhibitions may have to be overcome via deconditioning.

Failed back syndrome or post-laminectomy syndrome is a condition characterized by chronic pain following back surgeries. Many factors can contribute to the onset or development of FBS, including residual or recurrent spinal disc herniation, persistent post-operative pressure on a spinal nerve, altered joint mobility, joint hypermobility with instability, scar tissue (fibrosis), depression, anxiety, sleeplessness, spinal muscular deconditioning and even Cutibacterium acnes infection. An individual may be predisposed to the development of FBS due to systemic disorders such as diabetes, autoimmune disease and peripheral blood vessels (vascular) disease. Common symptoms associated with FBS include diffuse, dull and aching pain involving the back or legs.

But in the elderly several factors makes taking history more difficult and time-consuming. Many differences can be seen in geriatric anesthesia. First, the preoperative evaluation of the geriatric patient is typically more complex than that of the younger patient because of the heterogeneity of this patient group and the greater number and complexity of comorbid conditions that usually accumulate with age. Perioperative functional status can be difficult to predict because many elderly patients have reduced preoperative function as a consequence of deconditioning, age-related disease, or cognitive impairment. This makes it difficult to adequately assess the patient’s ability to respond to the specific stresses associated with surgery.

It may also manifest as mild hyperinflammation, airway obstruction and in that case, patient may be subject to steroid treatment to treat deconditioning. Complications from prolong exposure includes bronchiolitis obliterans and other secondary infections such as pneumonia due to injuries on the mucous membrane from pulmonary edema and inhibition of immune system by nitrogen dioxide. Nitrogen dioxide inhalation can result in short and long-term morbidity or death depending on the extent of exposure and inhaled concentration and the exposure time. Illness resulting from acute exposure is usually not fatal although some exposure may cause bronchiolitis obliterans, pulmonary edema as well as rapid asphyxiation.

LaVey also developed his own Black Mass, which was designed as a form of deconditioning to free the participant from any inhibitions that they developed living in Christian society. He noted that in composing the Black Mass rite, he had drawn upon the work of the French fiction writers Charles Baudelaire and Joris-Karl Huysmans. LaVey openly toyed with the use of literature and popular culture in other rituals and ceremonies, thus appealing to artifice, pageantry, and showmanship. For instance, he published an outline of a ritual which he termed the "Call to Cthulhu" which drew upon the stories of the alien god Cthulhu authored by American horror writer H. P. Lovecraft.

Additionally, human space travelers are often not well hydrated, have a 10-15% decrease in intravascular fluid (plasma) volume, and may lose both their preflight muscular and cardiovascular fitness levels as well as their thermoregulatory capabilities. As a result, they may become less heat- acclimated or may acquire an altered thermal sensitivity. Alterations in thermoregulation in association with spaceflight could significantly affect a variety of spaceflight-associated activities including exercise as a countermeasure to muscle atrophy, cardiac deconditioning, and bone loss; extravehicular activity (EVA); and vehicle landing and egress. EVA suits and launch and entry or advanced crew escape suits (ACES) worn by ISS and Shuttle crewmembers are designed to provide an impermeable barrier between the wearer and the external environment.

Surgical methods of treating fractures have their own risks and benefits, but usually, surgery is performed only if conservative treatment has failed, is very likely to fail, or likely to result in a poor functional outcome. With some fractures such as hip fractures (usually caused by osteoporosis), surgery is offered routinely because non-operative treatment results in prolonged immobilisation, which commonly results in complications including chest infections, pressure sores, deconditioning, deep vein thrombosis (DVT), and pulmonary embolism, which are more dangerous than surgery. When a joint surface is damaged by a fracture, surgery is also commonly recommended to make an accurate anatomical reduction and restore the smoothness of the joint. Infection is especially dangerous in bones, due to the recrudescent nature of bone infections.

The aim of treatment was to help the participant gradually return to appropriate physical activities, reverse the deconditioning, and thereby reduce fatigue and disability. 641 patients meeting the Oxford criteria for CFS were recruited, and were assigned approximately evenly to the four treatment conditions. %2 weeks after the commencement of the trial, self-reported fatigue scores were significantly lower and self-rated physical function scores significantly higher for the GET and CBT groups than for the SMC and APT groups. At 52 weeks post-treatment, average scores on a 6-minute walking distance test were significantly higher for the GET group than for the other groups. However, the mean distance walked (334 metres) was still well below the mean for healthy elderly people (631 metres).

Until STS-41, previous research had shown that during the process of adapting to microgravity, animals and humans experienced loss of bone mass, cardiac deconditioning, and after prolonged periods (over 30 days), developed symptoms similar to that of terrestrial disuse osteoporosis. The goal of the STS-41 Physiological Systems Experiment, sponsored by the Ames Research Center and Pennsylvania State University's Center for Cell Research, was to determine if pharmacological treatments would be effective in reducing or eliminating some of these disorders. Proteins, developed by Genentech of San Francisco, California, were administered to eight rats during the flight while another eight rats accompanying them on the flight did not receive the treatment. 20 September 1990 – Rare view of two Space Shuttles (STS-35 and STS-41) on adjacent KSC Launch Complex 39 pads.

Burroughs believed that Scientology's practice of auditing had helped him resolve some traumatic life experiences, and "came to regard the E-Meter as a useful device for deconditioning". However, he had "growing doubts about some of the other Scientology technology, and grave reservations about their policy as an organisation". He became frustrated by the authoritarian nature of the organization, and as biographer Ted Morgan writes, "... had hoped to find a method of personal emancipation and had found instead another control system." In a similar vein, Burroughs was both intrigued by Scientology's study of language, but felt distaste for the way it was being utilized: > They [the Church of Scientology] have a great deal of very precise data on > words and the effects produced by words – a real science of communication.
