Wheelchair and life
Dependence on Daily Transportation: Wheelchairs are a crucial tool for wheelchair users to achieve daily mobility. When using public transportation, although subways have accessible ramps, wheelchair users may become disoriented due to numerous transfer lines and unclear signage, increasing the difficulty of travel. When taking buses, some older buses lack wheelchair lifts, and even at stops with low-floor bus stops, boarding can still be difficult if the bus stops in the wrong location.While trains have wheelchair-accessible carriages, the space can sometimes be cramped, making it difficult for wheelchairs to maneuver. In more humane cities, not only are accessible ramps connecting important locations, but dedicated staff are also stationed on subway lines to assist wheelchair users. Furthermore, some bus companies are gradually increasing the number of buses equipped with lift platforms to improve the travel experience for wheelchair users.
Wheelchairs present different challenges when navigating different terrains. On slopes, wheelchair users need sufficient upper body strength to propel the wheelchair uphill, and if the slope is steep, assistance from others may be necessary. When descending, it is crucial to control speed to prevent loss of control due to excessive speed. On gravel roads, wheelchair tires are easily affected by bumps, resulting in decreased stability and potentially accelerated tire wear over time.Grassy areas pose a significant challenge for wheelchairs, as soft grass can easily cause them to get stuck, making it difficult to move forward. To address these challenges, wheelchair users often adjust the wheelchair’s drive mechanism, choose suitable tires, or use assistive devices.
Adapting to Home Life: To enable wheelchair users to live freely and comfortably at home, the home environment needs to be modified in many ways. First, doorways need to be widened. Generally speaking, the width of ordinary doorways is a bit narrow for wheelchairs to pass through. Doorways need to be widened to at least 80 centimeters to ensure that wheelchairs can easily enter and exit various rooms.Furniture height also needs to be lowered. For example, lowering the kitchen countertop will make it easier for wheelchair users to cook. The height of the bathroom sink and toilet should be adjusted to facilitate daily washing and toileting. Accessible toilets should also be provided, and safety facilities such as handrails should be installed to prevent users from falling when getting up or moving.
In indoor spaces, wheelchair mobility largely depends on furniture arrangement. Properly placed furniture, leaving ample passageways, can prevent wheelchairs from bumping into furniture during movement. For example, a certain distance should be maintained between the sofa and coffee table in the living room to allow wheelchair users to move freely. Here are some stories of wheelchair users at home, like Xiao Li, who, after home renovations, is able to cook independently, from washing and chopping vegetables to stir-frying. The accessible facilities in the kitchen have allowed him to rediscover the joy of life.After installing accessible facilities in his bathroom, Xiao Zhang no longer needs help with washing and grooming, greatly improving his self-care ability and dignity. This fully demonstrates the importance of wheelchairs in their home life; they are indispensable partners in achieving independent living.
