BackgroundHamstring strain injuries are the most common type of injury in elite football and are associated with a high risk of reinjury, particularly those involving the intramuscular tendon (IMT). Limited information is available regarding the rehabilitation and return to sport (RTS) processes following such injuries. This case study describes the clinical presentation of an elite football player following IMT hamstring injury, their on- and off-pitch rehabilitation alongside performance monitoring throughout RTS and beyond.Case scenarioAn elite football player suffered a grade 2c hamstring injury during an English Premier League (EPL) match. The player underwent early post-injury management, alongside progressive off-pitch physical preparation. The ‘control-chaos continuum’ was used as a framework for on-pitch rehabilitation to prepare the player for a return to full team training and competition. Objective and subjective markers of the player's response to progressive on- and off-pitch loading were monitored throughout RTS and beyond.OutcomesThe player returned to on-pitch rehabilitation after 11 days, to full team training having achieved weekly pre-injury chronic running load outputs after 35 days and played in the EPL 40 days post-injury. The player did not suffer reinjury for the rest of the EPL season.ConclusionAn understanding the unique structural and mechanical properties of the IMT, alongside expected RTS timeframes are important to inform rehabilitation and decision-making processes post-injury. Performance and frequent load-response monitoring throughout RTS and beyond, in conjunction with practitioner experience and effective communication are critical in facilitating effective RTS and reduce risk of reinjury following IMT injury.  相似文献

目的探讨微信平台延续性护理对老年腰椎间盘突出症术后患者康复及生活质量的影响。方法选取2015年6月—2018年5月在郑州市骨科医院接受手术治疗的老年腰椎间盘突出症患者96例进行研究。对照组行常规延续性护理,观察组行微信平台延续性护理。对比两组康复效果、治疗依从性及生活质量。计数资料采用卡方检验分析,计量资料采用t检验分析。结果观察组有效率为95.83%,明显高于对照组的81.25%。观察组总依从率为91.67%,明显高于对照组的77.08%。干预前两组生活质量量表得分相当,治疗后两组生活质量均有明显改善,但观察组改善程度更为明显。结论微信平台延续性护理相比传统延续性护理可明显提高老年腰椎间盘突出症患者康复效果、提高治疗依从性和改善生活质量。  相似文献

BackgroundThe Measure of Processes of Care (MPOC) questionnaires evaluate Family-Centered Practice (FCP) in services for children with developmental disorders. The MPOC-20 and MPOC-SP are completed by parents and by rehabilitation professionals, respectively, and are widely used in several countries.ObjectivesTo translate and cross-culturally adapt the MPOC-20 and MPOC-SP to Brazilian Portuguese and evaluate their reliability and internal consistency.Methodsthis study included translation, back-translation, cognitive interviews, testing of the pre-final versions, analysis of reliability and of internal consistency of the final versions. Respondents included parents and rehabilitation professionals from rehabilitation centers in four capital cities in Brazil.ResultsTranslation and cultural-adaptation procedures ensured the Brazilian versions were understandable and semantically equivalent to the original MPOC-20 and MPOC-SP. Pre-final and final versions were analyzed and vetted by the original authors. The MPOC-20 internal consistency Cronbach's alpha varied between 0.61 and 0.91 (n = 107), the test-retest reliability ICC varied between 0.44 and 0.83 and the standard error of measurement varied between 0.66 and 0.85 (n = 50). The MPOC-SP internal consistency Cronbach's alpha varied between 0.52 and 0.83 (n = 92), the test-retest reliability ICC between 0.83 and 0.90, and the standard error of measure between 0.34 and 0.46 (n = 62).ConclusionThe Brazilian versions of the MPOC-20 and the MPOC-SP are in general stable and sufficiently reliable. They are relevant to the evaluation of FCP and provide information that can improve health services and ensure better care.  相似文献
