Study investigated the effect of dynamic sitting behavior on cutaneous and subcutaneous tissue oxygenation in individuals with spinal cord disorders. Nine out of 10 male participants aged 46 to 68 years with spinal cord disorder completed the study. Participants were seated in the Dynasit chair, an experimental computer aided simulator chair containing mechanical concepts for postural adjustments, regulation of tuberal load, and pelvic rotation. An experiment was carried out in which a dynamic sitting pattern was imposed during a 39 minute protocol consisting of a series of actuated changes in posture, tuberal load, and pelvic orientation. Effects of these changes on cutaneous and subcutaneous buttock tissue oxygenation were assessed via transcutaneous measurement of tissue oxygenation. Nonparametric statistical analyses were used to investigate the ability of the Dynasit chair to impose dynamic sitting behavior. Results showed significant positive effects of actuated changes in tuberal load on cutaneous and subcutaneous tissue oxygenation. The authors conclude that the Dynasit chair is effective in imposing dynamic sitting behavior in individuals with a spinal cord disorder and consequently might reduce the chance of tissue degradation.
