A three-wheeled wheelchair was built in 1655 or 1680 by a disabled German man, Stephan Farffler, who wanted to be able to maintain his mobility. Since he was a watch-maker, he was able to create a vehicle that was powered by hand cranks. In 1789, two French inventors developed a three wheeled vehicle, powered by pedals; They called it the tricycle. 19th century tricycle used in Iran In 1818, British inventor Denis Johnson patented his approach to designing tricycles.[clarification needed] In 1876, James Starley developed the Coventry Lever Tricycle, which used two small wheels on the right side and a large drive wheel on the left side; power was supplied by hand levers. In 1877, Starley developed a new vehicle he called the Coventry Rotary, which was "one of the first rotary chain drive tricycles." Starley's inventions started a tricycling craze in Britain; by 1879, there were " twenty types of tricycles and multi-wheel cycles ... produced in Coventry, England, and by 1884, there were over 120 different models produced by 20 manufacturers." The first front steering tricycle was manufactured by The Leicester Safety Tricycle Company of Leicester, England in 1881 which was brought to the market in 1882 costing £18. They also developed a folding tricycle at the same time.Buy online Tricycle for handicapped and disabled at lowest price and cheap cost in india from wheelchair india online shopping store of Tricycle manufacturer, distributor, dealer and supplier of variety of Tricycles at low price in india for handicapped and disability product like Disabled Tricycle Deluxe Double Hand Drive, Tricycle Deluxe Single Hand Drive, Tricycle Standard Double Hand Drive, Tricycle Regular Single Hand Drive, Standard Single Hand Drive Tricycle, along with that we offer huge discount.

By Dr. Paul Jerard, E-RYT 500 Understanding Yoga anatomy is critical to understanding the benefits and risks, of practicing and teaching, Yoga asanas or pranayama techniques. The study of human anatomy will teach you about the organization and intricate functioning of the human skeleton, muscles, internal organs, ligaments, tendons, and cartilage. A good Yoga instructor will have a firm foundation in the anatomy of Yoga, so that he or she is aware of the correct alignment of Yoga poses and the safest way to move in and out of the asanas. A firm understanding of the anatomy of the respiratory system is also very helpful for teaching Yoga students correct breathing techniques, which will leave them with a feeling of energized calmness.

A Tricycle is a type of human-powered land vehicle powered by the arms rather than the legs, as on a bicycle. Most handcycles are tricycle in form, with two coasting rear wheels and one steerable powered front wheel. Despite usually having three wheels, they are also known as handbikes. Many manufacturers have designed and released hand-powered recumbent trikes, or handcycles. Handcycles are a regular sight at HPV meets and are beginning to be seen on the streets. These usually follow a delta design with front wheels driven by standard derailleur gearing powered by hand cranks. Brake levers are usually mounted on the handholds which are usually mounted in phase, unlike pedal cranks, which are usually 180° out of phase. This allows the rider to more easily use their torso to help propel the cycle. The entire crank assembly and the front wheel turn together, allowing the rider to steer and crank simultaneously. Single-Hand-Drive-Tricycle come in a variety of styles, making them accessible to people with a wide variety of disabilities. There are also hybrids between a handcycle, a recumbent bike and a tricycle. Fork steer handcycles represent the majority of handcycles sold. They work well for both low and high-level spinal injuries, and most have adjustable footrests, seat angle, and come with a variety of gearing, wheel and tire configurations depending on intended use: racing, recreation, or touring. Manufacturers of this type of handcycle include Invacare (Top End), Intrepid Equipment, Varna, Schmicking and Sunrise Medical. Lean steer handcycles are another type of handcycle. In this type of handcycle the rider leans into the turn to steer. There is a longer learning curve with lean steer handcycles, and they are significantly less stable at high speed. The lean steer system feels similar to mono skiing: using your whole body to steer the handcycle. Lean steer handcycles can work well for lower-level injuries; although, some athletes with high-level di

We are not trying to create any hoax, nor do we intend to create any hype for no reason! A report by Australia's Breakthrough National Centre for Climate Restoration (BNCCR) claims that we have just another 31 years after which the climate change will cause more than 90 percent of humans to wipe out. So, if we do not mend our ways in harming the climate, by 2050, the human race will cease to exist!

By Faye Martins How can Yoga help stroke recovery? The fact that a human can survive and potentially recover from a stroke is a testament to the intricate design of the brain. A stroke essentially kills an area of the brain, thus causing the typical symptoms of a stroke. Depending on the location, the brain can make adjustments and compensations, basically rewiring the other areas of the brain to perform the duties of the damaged section of the brain. This is an amazing feat.

Ergonomic wheelchair and it's Uses Manual wheelchairs are those that require human power to move them. Many manual wheelchairs can be folded for storage or placement into a vehicle, although modern wheelchairs are just as likely to be rigid framed. Manual or self-propelled wheelchairs are propelled by the occupant, usually by turning the large rear wheels, from 20-24 inches (51-61 cm)in average diameter, and resembling bicycle wheels. The user moves the chair by pushing on the handrims, which are made of circular tubing attached to the outside of the large wheels. The handrims have a diameter that is slightly less than that of the rear wheels. Skilled users can control speed and turning and often learn to balance the chair on its rear wheels - do a wheelie. The wheelie is not just for show - a rider who can control the chair in this manner can climb and descend curbs and move over small obstacles. http://www.wheelchairindia.com http://www.wheelchairindia.com/Wheelchair/1/ERGONOMIC-WHEELCHAIR

A tricycle for special needs is made so can go along for the ride in wheelchair or sitting in a special seat, both of which are attached right in front of another adult's trike. Tricycles to accommodate a vast array of special needs. Hand-pedaled recumbent tricycles are available for those without the use of their legs. Children, teens and adults with cerebral palsy and similar disorders can select tricycles specially designed to increase strength and coordination. Caregivers to autistic children can ride with their child on tandem special needs tricycles built to accommodate one adult and one child rider. Accessories are also available to convert standard trikes to suit specific needs. The objective of tricycle design is to produce wheelchairs that perform well and can provide appropriate seating and postural support without compromising strength, durability and safety. A Hand Driven Tricycle, abbreviated to trike is a three-wheeled passenger vehicle, usually carrying a single rider. The tricycle consists of a motorbike and an attached passenger sidecar and should not be confused with the tricycle. The trike is a motorized three-wheeled pedicab. Human-powered trikes are powered by pedals or hand cranks. Motorized trikes use motorcycle or scooter,or electric motors. Tricycles tend to be used for commercial purposes: such as "pedicabs" for transport passengers, and freight trikes for making deliveries. In the adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children and senior adults alike for their apparent stability versus a bicycle; but a conventional trike has poor dynamic lateral stability, and the rider must take care when cornering to avoid tipping the trike over.
