OBJECTIVE To determine differences in rehabilitation gains made by people with an acquired brain injury undergoing staged community-based brain injury rehabilitation (SCBIR) at different times between injury and admission. METHOD Retrospective cohort analysis of routinely collected demographic and rehabilitation data from clients admitted to SCBIR service 2011-2017 (n=92). Outcome measures: Mayo-Portland Adaptability Inventory-4 (MPAI-4) and UK Functional Assessment Measure (UK FIM+FAM) collected on admission and annually thereafter until discharge. Analysis was stratified by time since injury on admission: 'Early' (<1 year (n=36)), 'Middle' (1-2 years (n=34)) and 'Late' (>2 years (n=22)). Between-group differences were tested using bootstrapped one-way ANOVA. Within-group differences were tested using paired T tests. RESULTS Total cohort made significant gains in MPAI-4 and UK FIM+FAM total and all subscales (p = .001). Early group made greatest change in all subscales of both outcome measures (p < .01). Middle cohort improved significantly in all subscales (p < .02) excluding MPAI-4 Adjustment. Late cohort still made statistically significant gains in all UK FIM+FAM subscales (p < .05) and MPAI-4 Participation (p < .01). Item level changes are presented. CONCLUSION More than 2 years after injury, people are able to make improvements in participation and functional independence following SCBIR.

从获得性脑损伤到接受社区康复之间的时间：认知和功能获得的差异。

目的确定后天性脑损伤患者在受伤和入院之间的不同时间进行分阶段社区性脑损伤康复（SCBIR）所获得的康复收益的差异。方法对2011-2017年接受SCBIR服务的客户常规收集的人口统计和康复数据进行回顾性队列分析（n = 92）。成果措施：入院时收集梅奥-波特兰适应性清单4（MPAI-4）和英国功能评估方法（UK FIM + FAM），此后每年收集一次，直至出院。根据入院受伤后的时间进行分析：“早期”（<1年（n = 36）），“中”（1-2年（n = 34））和“晚期”（> 2年（n = 22） ））。使用自举式单向方差分析测试组间差异。组内差异使用配对T检验进行检验。结果总队列在MPAI-4和UK FIM + FAM总分及所有子量表中均取得了显着增长（p = .001）。早期组在两种结果量表的所有子量表中的变化最大（p <.01）。除MPAI-4调整外，所有其他量表的中队列均显着改善（p <.02）。在所有英国FIM + FAM分量表（p <.05）和MPAI-4参与（p <.01）方面，晚期队列仍具有统计学上的显着增长。显示了项目级别的更改。结论受伤后2年以上，SCBIR后人们能够改善参与和功能独立性。.02）（不包括MPAI-4调整）。在所有英国FIM + FAM分量表（p <.05）和MPAI-4参与（p <.01）方面，晚期队列仍具有统计学上的显着增长。出现项目级别更改。结论受伤后超过2年，人们在SCBIR后能够改善参与和功能独立性。.02）（不包括MPAI-4调整）。在所有英国FIM + FAM分量表（p <.05）和MPAI-4参与（p <.01）方面，晚期队列仍具有统计学上的显着增长。显示了项目级别的更改。结论受伤后超过2年，人们在SCBIR后能够改善参与和功能独立性。
