Abstract：
Home exercise programs are beneficial in managing frozen shoulder (FS), yet adherence remains challenging. This pilot study introduces the remote app, Defrozen, designed for home exercises and assesses its feasibility and clinical outcomes in FS patients undergoing intra-articular and sub-acromial corticosteroid treatment. Over a four-week period, patients used the Defrozen-app, engaging in guided exercises. The feasibility of the intervention was assessed through several measurement scales, including adherence, the Technology Acceptance Model 2 (TAM2), the System Usability Scale (SUS), and User Satisfaction and Engagement (USE). Clinical outcomes included pain scale, Oxford Shoulder Score (OSS), Quick Disability of the Arm, Shoulder, and Hand (QuickDASH) Score, and passive range of motion. The TAM2 results indicated high perceived usefulness (4.5/5), ease of use (4.8/5), and intention to use (4.4/5); the SUS score was high at 81.7/100, complemented by USE scores reflecting ease of learning (4.9/5) and satisfaction (4.3/5). Clinical outcomes showed significant pain reduction, improved shoulder function, reduced shoulder-related disability, and increased shoulder range of motion. These findings suggest the Defrozen-app as a promising solution for FS, significantly improving adherence and showing potential to enhance clinical outcomes. However, these clinical outcome results are preliminary and necessitate further validation through a large-scale randomized controlled trial to definitively confirm efficacy and assess long-term benefits.
摘要：
家庭锻炼计划有益于管理冻结肩（FS），然而，坚持仍然具有挑战性。这项试点研究介绍了远程应用程序，除霜,设计用于家庭锻炼，并评估其在接受关节内和肩峰下皮质类固醇治疗的FS患者中的可行性和临床结局。在四周的时间里，患者使用了Defrozen-app，从事指导性练习。通过几个测量量表评估干预的可行性，包括坚持，技术接受模型2(TAM2)，系统可用性量表(SUS)，以及用户满意度和参与度(USE)。临床结果包括疼痛量表，牛津肩评分（OSS），手臂的快速残疾，肩膀,和手（QuickDASH）得分，和被动运动范围。TAM2结果表明，感知有用性较高(4.5/5)，易用性（4.8/5），和使用意向（4.4/5）；SUS得分高，为81.7/100，辅以反映学习简易性（4.9/5）和满意度（4.3/5）的USE得分。临床结果显示疼痛显著减轻，改善肩部功能，减少与肩部相关的残疾，增加了肩膀的活动范围。这些发现表明Defrozen-app是FS的一个有前途的解决方案，显着提高依从性并显示出增强临床结局的潜力。然而,这些临床结局结果是初步的,需要通过大规模随机对照试验进一步验证,以明确确认疗效并评估长期获益.
