When walking, a large percentage of the ground reaction force or vibration is lost or absorbed before it can be transmitted beyond the thighs. When using a wheelchair, being in a seated position to move can mean increased vibration through the legs and upper body, and often for a prolonged period of time.
RESNA describes wheelchair users as “particularly at risk from whole body vibration”. From a health professional and biomechanical perspective, it is ideal for vibration to be redirected at the earliest stage possible.
Consequences of over exposure to vibration on the body
Increased exposure to whole body vibration has been shown to induce or exaggerate back pain, neck pain, fatigue, spasticity, and pressure injuries. The consequences of these for daily life as a wheelchair user are a serious issue.
