and is lighter, less bulky and easier to propel than a wheelchair. Wheelchairs and scooters Wheelchairs and mobility scooters substitute for walking by providing a wheeled device on which the user sits. Wheelchairs may be either manually propelled (by the user or by an aide) or electrically powered (commonly known as a "powerchair"). There are different types of wheelchair power add-ons that turn any manual wheelchair into a power assisted. Mobility scooters are electrically powered, as are motorized wheelchairs. Wheelchairs and Scooters are normally recommended for any individual due to significant mobility/balance impairment. A Registered Occupational Therapist or Physiotherapist (few cases) are able to provide object and clinical testing to ensure proper and safe device recommendations. Stairlifts and similar devices A stairlift is a mechanical device for lifting people and wheelchairs up and down stairs. Sometimes special purpose lifts are provided elsewhere to facilitate access for those with disabilities, for example at entrances to raised bus stops in Curitiba, Brazil. A wheelchair lift is specifically designed to carry the user and the wheelchair. This can either be through floor or utilizing the staircase. Others Mobility aids may also include adaptive technology such as sling lifts or other patient transfer devices that help transfer users between beds and chairs or lift chairs (and other sit-to-stand devices), transfer or convertible chairs. Knee scooters help some users. As people start to live longer mobility is about for many reclaiming aspects of independence which before were denied to them.
