| Motion It is a sad truth about wheelchairs that many of these ostensibly helpful devices end up precipitating new injuries instead. Of course, getting around is essential to an active life, but sitting in the same position day after day can have devastating effects on your lower back and legs. No wonder a number of ergonomists have recommended improving the seat pans and padding on these ubiquitous devices. Believe it or not, sitting can be dangerous. Problems as diverse as neuropathy, neck strain and spinal infections can result if blood isn't circulating properly to your body's nerve centers, and the worst cases can lead to meningitis. At the very least, you can experience a slow atrophy of your leg muscles resulting from complications associating with blood pooling. That's why the very best wheelchair cushions tend to keep your body in a more dynamic stance. Many of these are filled with fluids such as viscous gels or mixtures of water and air that move your weight distribution around throughout the day. Because fluids distribute gravity far better than solid foams, you may feel more like you're floating on a kinetic medium than pressed into something less forgiving. Ergonomics is no joke, and the safety of wheelchair- bound individuals is perhaps the foremost example. If you find yourself growing progressively more uncomfortable throughout the day on that shapeless seat pan of stretched canvas, you may find something with a little more structure salvages your experience. The right wheelchair cushion can free you up to appreciate that mobile lifestyle once again. |
