Electric wheelchair Cheap Will Butcher Jersey , also called electric-powered wheelchair, motorized wheelchair, or powerchair, any seating surface with wheels affixed to it that is propelled by an electrically based power source, typically motors and batteries. The first motor-powered wheelchairs appeared in the early 1900s; however, demand for them did not exist until after World War II.

The advent of the power base, which sits beneath the seat and contains the motor and batteries, allowed for significant mechanical The first commercially produced electric wheelchairs were merely heavy-duty manual folding-frame wheelchairs that were powered by lead-acid batteries, motors, drive belts, and pulleys. Those systems, known as conventional power wheelchairs, were very simplistic. They required the use of a joystick to control the wheelchair’s movement, and programmability did not exist. The seating system typically consisted of a sling seat and back upholstery, which significantly limited postural support for the individual.

advancements in electric wheelchairs. The power base separated the electric wheelchair into two components: the base, which provided the mobility, and the seating system, which provided the postural support. At the same time that a shift from a conventional power wheelchair to a power-base wheelchair was taking place, significant advancements were occurring in electronic systems. Some of those mechanical and electrical advancements included the ability to add power tilt and recline systems and programmable performance settings (e.g., forward speed, turning speed, and acceleration). Joysticks, the most basic and common devices used to control electric wheelchairs, came to resemble those used with computer game consoles. Advancements in control systems allowed individuals to control a wheelchair by using any voluntary movement. For example, some electric wheelchairs can be controlled by using head movement, breath actuation, tongue movement, or lower extremity control.

Two types of drive mechanisms are used on electric wheelchairs: indirect drive and direct drive systems. Indirect drive systems (pulleys and drive belts) are used on conventional electric wheelchair, whereas direct drive systems (gear boxes) are used on power-base wheelchairs. The vast majority of contemporary electric wheelchairs use a power base with a direct drive system. Typically, two 12-volt batteries in series (24-volts total) are needed to power an electric wheelchair. Wet cell batteries, gel batteries, or absorbent glass mat (AGM) batteries may be used in electric wheelchairs. Electric wheelchair batteries typically are rechargeable.

Electric wheelchairs also can be classified on the basis of the location of the drive wheels. There are three types of electric wheelchairs: front-wheel drive, mid- or centre-wheel drive, and rear-wheel drive. Traditionally, rear-wheel drive electric wheelchairs were preferred because of their similarity to manual wheelchair in design and maneuverability. However, centre-wheel drive wheelchairs have gained popularity because they provide increased maneuverability.

Push-rim-activated power-assisted wheelchairs (PAPAWs) incorporate features of both manual and electric wheelchairs. A PAPAW typically consists of an ultralightweight wheelchair with an external power source (batteries and motors). It complements rather than replaces an individual’s ability to manually propel the wheelchair. The push-rim contains sensors that detect the direction and magnitude of force applied to it by the individual. The motors are then activated and assist in the propulsion of the wheelchair.

Ketosis diet plans, also known as ketogenic diets, include food plans that are surprisingly low in carbs. Carbohydrates tend to be, of course, one of the main sources of energy for your body. Carbs release energy into your body, which is a key component to its typical functioning. Whenever you limit your intake of carbohydrates your body doesn’t have energy to burn, which could basically mean you die. The good news is, your body is smart enough to know what to do. If your body feels threatened by an inadequate ingestion of carbohydrates, it immediately begins looking for energy by burning stored fat. With any luck, you are beginning to catch our drift. It just seems logical that if fat loss is your goal, then a ketogenic diet, which makes your body to burn fat for fuel, should be a good thing. Well yes, of course it will, providing you are actually sticking with the basic calories in and calories out rule.


Some people say that ketogenic diet plans are dangerous. The truth is, they are actually safe; the trouble seems to be that some individuals get mixed up relating to the words “ketoacidsosis” and “ketogenic”. Ketoacidosis is quite damaging and only occurs in individuals who have diabetes, once the amount of sugars in their blood goes out of control. Clearly, we do not like to mistake these 2 terms. Ketosis has been shown to not only assist in your struggle to lose weight, but it also helps defend against illness.


Ketosis and its effects on weight reduction have been under investigation for years. In many of these tests, people who were on the ketogenic regimen said they seemed to not be as hungry as they were before. This is usually due to the high protein foods in ketogenic diet plans. Protein can be a major role player in how fast we start to feel full, that, needless to say makes you less hungry. Individuals who do not have to actively work to control calories are the ones on reduced carbohydrate diet plans, where as men and women on low fat diets have to be concerned with calorie counting.


It’s necessary that you be a little mindful with many low carbohydrate diet programs – they often times incorporate an excessive amount of saturated fat to be considered h.
