Objective To investigate the effectiveness and interactions of 2 methods of pressure ulcer prevention, wheelchair cushions and pressure relief maneuvers, on interface pressure (IP) and blood flow of the buttocks. Design Within-subject repeated measures. Setting Rehabilitation center. Participants Wheelchair users with a spinal cord injury or disorder (N=17). Interventions Participants performed 3 forward leans and 2 sideward leans with different degrees of lean while seated on each of 3 different wheelchair cushions. Main Outcome Measures IP measured with a custom sensor and blood flow measured with laser Doppler flowmetry were collected at the ischial tuberosity. Results Pressure relief maneuvers had a significant main effect on the ischial IP (P<.001 all maneuvers except for the small frontward lean resulted in a significant reduction ip compared with upright sitting. blood flow significantly varied across postures during sitting and forward leans being lower than full intermediate both sideward directions.> Conclusions The results of the study highlight the importance of positioning wheelchair users in a manner that facilitates in-seat movement. Regardless of the cushion being used, the pressure relief maneuvers resulted in very large reductions in IPs and significant increases in buttock blood flow. Only the small frontward lean was shown to be ineffective in reducing pressure or increasing blood flow. Because these pressure relief maneuvers involved postural changes that can occur during functional activities, these pressure relief maneuvers can become a part of volitional pressure relief and functional weight shifts. Therefore, clinical instruction should cover both as a means to impart sitting behaviors that may lead to better tissue health. |
