University of Pittsburgh researchers have developed StairAbility, an adaptable stair-climbing device. StairAbility is a modular system, with adaptable attachments that can readily be integrated with existing stairlift systems to aid ascent and decent of stairs. Attachments can also be used to assist with transporting heavy objects, or even wheelchairs up and down stairs. StairAbility could dramatically improve the lives of older adults, allowing them to live comfortably in their own home, safely navigating stairs, and promote aging in place.
StairAbility, a modular, adaptable stair-climbing device has been developed. StairAbility can be integrated into existing Stairlift technology. Unlike stairlifts, StairAbility supports users with some mobility to continue to climb stairs, vital for mobility and strength.
Description
Navigating stairs safely is essential for older adults living in split-level or two-story homes. With age, navigation of stairs and the home in general can become more challenging and unsafe, leading to falls or loss of independence and quality of life. Research has shown those with restricted or decreased movement in their home and surroundings are over four times more likely than those with unrestricted movements, to require a move to a nursing home facility. More than a fifth of older adults in the US have reduced mobility, and with a growing aging population there is a need to develop accessible, cost-effective, easy-to-use aids to stair use to allow older adults live independently in their own homes. Independent living and active aging are known to reduce the risk of falls and cognitive impairment and improves physical and mental health reducing the need for elder care.
Applications
• Independent living
• Active aging
Advantages
Stairlifts are commonly used assistive technology to help users ascend and descend stairs. A user is seated in a chair and carried by the stairlift up or down the stairs. However, stairlifts have several shortcomings including not being suitable for narrow stairs and limiting the user’s range of motion. In addition, some users could use stairs with some assistance from a moving rail to maintain strength, balance, and mobility, but use a stairlift as no alternative exists.
StairAbility overcomes these challenges. Firstly, StairAbility is a modular system that can seamlessly integrate into existing stairlift systems. The chair of a stairlift can be removed and replaced with adaptable device attachments including an ergonomic handlebar to support users while they climb stairs, a wheelchair platform lift, and a basket to transport heavier items (e.g., mobility aids or laundry). These attachments mean a user can have support to use stairs when they are physically able, but if their function declines. StairAbility can be adapted to match their needs allowing users to continue to live independently and safely in their home.
Invention Readiness
A prototype device has been built with an ergonomic handlebar attachment. The handlebar can be folded when not in use so as not to impede stair use for other users. Work is now required to optimize design of other attachments.
