Abstract

The purpose of this study was to examine the use of the absorbed power (AP) in describing whole-body vibration for individuals with a spinal cord injury (SCI) during manual wheelchair propulsion. The amplitude of the AP and the vertical acceleration were calculated in the frequency domain. The AP is more proficient than the acceleration metric at accentuating the frequencies related to whole-body vibration. The acceleration metric may be underestimating the amplitude of the vibration seen by an individual with a SCI especially at frequencies related to the natural frequency of the human body
