Dynamic stiffness and transmissibility of commercially available wheelchair cushions using a laboratory test method

A variety of factors have been associated with back and neck pain, such as inadequate postural sup- port, stress, and vibration exposure. Substantial evi- dence links vibration exposure with spinal injuries, and driving has been found to be the most common way to transmit vibration to the human body. Because wheelchair users spend long periods of time propel- ling their wheelchairs, they may be exposed to simi- lar risks. Our study evaluates commercial wheelchair cushions– characteristics for reducing or amplifying vibration exposure to wheelchair users with two labo- ratory test methods. Among the cushions tested, the air-bladder cushions had lower vibration transmissi- bility than the foam- or gel-based cushions. |
