Applying ISO 16840–2 Standard to differentiate impact force dissipation characteristics of selection of commercial wheelchair cushions

Martin Ferguson-Pell, PhD, et al.

The properties of wheelchair cushions influence the cushion’s comfort and ability to protect users from excessive forces during everyday activities such as riding over rough ground or bumping down curbs. We used an international standard test method (called ISO 16840–2) to determine the impact damping characteristics of 36 commercial wheelchair cushions. We identified two groups with distinctly different impact damping characteristics: (1) cushions that were effective at damping impacts rather than transmitting them to the body and (2) cushions that were less effective at damping impacts but had other properties important to users. Wheelchair cushion selection is a process of selecting characteristics that meet the individual’s needs. The goal of ISO 16840–2 is to establish objective methods of measuring wheelchair cushion characteristics to help users compare products. Our research helps establish the most effective measurements when using ISO 16840–2 to identify cushions that are particularly good at absorbing impacts during typical wheelchair use.
