轮椅使用者与脊髓损伤（SCI）在发展压力损伤（pi）的高风险。进行重量转移是预防PI压力管理的主要方法；然而，由于缺乏感觉，脊髓损伤患者可能对自己的减压能力缺乏信心。实时的座椅界面压力映射反馈可以部分替代感官反馈，从而提高个人的信心。我们的目的是研究通过提供实时、按需的座椅界面压力映射反馈，如何影响脊髓损伤轮椅使用者压力管理的信心。在这项纵向、重复测量的研究中，脊髓损伤成人（N=23）完成了自我效能感问题，涉及与体重转移有关的4个因素的信心。我们评估了提供标准PI预防教育和获得实时压力图反馈对执行体重转移的置信度的影响。在获得实时压力图反馈的同时，学习如何进行重量转移，大大提高了移动到足够远的地方以缓解高风险区域压力的信心。坚持推荐的体重转移频率和持续时间的信心没有受到临床教育或使用压力图反馈的显着影响。对执行权重转移降低PI风险的信心在教育后增加了大部分，当增加压力图反馈时，会有轻微的额外增加。获得实时压力测绘反馈可以提高在临床环境中进行体重转移的信心，从而减轻压力，并展示了在家庭中进行体重转移的潜力。这项基于智能手机的压力测绘干预措施的初步探索强调了获得持续压力测绘反馈的价值，以提高管理压力的意识和信心。ClinicalTrials.gov NCT03987243;https://clinicaltrials.gov/study/NCT03987243
Wheelchair users with a spinal cord injury (SCI) are at a high risk for developing pressure injuries (PIs). Performing weight shifts is a primary method of pressure management for PI prevention; however, individuals with SCI may lack confidence in their abilities to perform adequate pressure relief due to their lack of sensation. Real-time seat interface pressure mapping feedback may provide partial substitution for sensory feedback such that an individual’s confidence is improved. We aim to examine how confidence for pressure management by wheelchair users with SCI was impacted by providing access to real-time, on-demand seat interface pressure mapping feedback. Adults with SCI (N=23) completed self-efficacy questions addressing confidence around 4 factors related to performing weight shifts in this longitudinal, repeated-measures study. We evaluated the impact of providing standard PI prevention education and access to live pressure map feedback on confidence levels for performing weight shifts. Access to live pressure map feedback while learning how to perform weight shifts resulted in significantly higher confidence about moving far enough to relieve pressure at high-risk areas. Confidence for adhering to the recommended weight shift frequency and duration was not significantly impacted by in-clinic education or use of pressure map feedback. Confidence that performing weight shifts reduces PI risk increased most following education, with slight additional increase when pressure map feedback was added. Access to live pressure mapping feedback improves confidence about performing weight shifts that relieve pressure when provided in the clinical setting and demonstrates potential for the same in the home. This preliminary exploration of a smartphone-based pressure mapping intervention highlights the value of access to continuous pressure mapping feedback to improve awareness and confidence for managing pressure.
