目的：研究两种预防压疮的方法，即轮椅垫和压力释放操作，对界面压力（IF）和臀部血流量的有效性和相互作用。设计：受试者内重复测量。设置：康复中心。参与者：患有脊髓损伤或疾病的轮椅使用者（N=17）。干预措施：受试者坐在3个不同的轮椅坐垫上，分别进行3次前倾和2次侧倾，并进行不同程度的倾斜。结果：减压动作对坐骨神经内压有显著的主效应（P
Objective: To investigate the effectiveness and interactions of 2 methods of pressure ulcer prevention, wheelchair cushions and pressure relief maneuvers, on interface pressure (IF) 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
