Prior risk prediction models designed to apply to all IRF patients in an IRF have achieved poor to acceptable predictive value, while better performance (C-statistic > 0.8) was attained by models isolated to specific impairment groups. Our aim was to determine if a general risk prediction model for ACT attained sufficient predictive utility when applied across all patients requiring IRF stay. We retrospectively reviewed adults admitted to an academic, rural IRF between January 2016 and September 2019. Predictors were selected based on variables that were statistically significant in prior studies, and covariates significant on bivariate analysis were included in a multivariable logistic regression model of ACT. The predictive utility of the model (bootstrapped C-statistic) was evaluated within each impairment group with greater than 100 patients. The analysis included 2275 patients (median age: 64 years; 57% male; 7% with unplanned ACT). Multivariable logistic regression of unplanned ACT demonstrated fair predictive utility [C-statistic: 0.75; 95% confidence interval (CI): 0.72-0.79], while applying the same risk score to individual impairment groups revealed highly heterogeneous C-statistics, from 0.81 (95% CI: 0.72-0.91) among patients with spinal cord dysfunction to 0.63 (95% CI: 0.50-0.75) among patients with amputation. Our derivation of a comprehensive risk score for ACT based on all patients admitted to IRF demonstrated fair predictive utility in the overall cohort, but predictive utility differed strongly across impairment groups. Further work is needed to develop personalized prediction of ACT risk based on the intersection of impairment group, clinical status at IRF admission, and pertinent medical and surgical history.","PeriodicalId":14301,"journal":{"name":"International Journal of Rehabilitation Research","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149016439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Main statistical method was latent class analysis. The mean age was 46.0 (17.8) years. Based on the distribution of 10 domains of functioning included in Oswestry Disability Index, four latent classes were identified: 'no or mild disability' (26% of the sample); 'moderate restrictions in sitting and traveling' (26%); 'moderate restrictions in standing and lifting and severe pain' (19%); and 'severe disability in most of the domains' (30%). Female sex (49 vs. 37%), obesity (48 vs. 28%), older age (63 vs.42%), greater pain severity (73-83 vs. 59-65%), and longer preoperative pain (27 vs. 20%) were associated with a higher likelihood of classification into a severe disability class. The results show that the functional difficulties of patients undergoing lumbar discectomy are not evenly distributed in the same way across individuals and are not simply a matter of variation at the individual level. It seems that there are larger classes whose disability domains are distributed in a different way than other classes. Belonging to a particular class can potentially be predicted by descriptive factors such as sex, age, pain intensity and pain history. This information can help identify risks that predict particularly severe disability and recognize the most common functional limitations that may be overlooked if all the patients are treated as a homogeneous group and the severity of disability is described by only one composite score .","PeriodicalId":14301,"journal":{"name":"International Journal of Rehabilitation Research","volume":" ","pages":"214-221"},"PeriodicalIF":1.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147868277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This retrospective observational study examined the measurement properties of 2MWT and 2'6MWT in 20 individuals with subacute stroke under two indoor walking path configurations: a rectangular path (11.5 × 5 m) requiring repeated turns and a 30-m straight path. Test-retest reliability, measurement error, convergent validity, and explanatory capacity were evaluated. Both indices showed excellent test-retest reliability (intraclass correlation coefficient = 0.973-0.988). Measurement error was higher on the rectangular path than on the straight path (minimal detectable change: 22.0-24.3 vs. 15.8-18.9 m). Correlations with the 6MWT were strong ( r = 0.936-0.988). The 2MWT distance explained 94 and 95% of the variance in 6MWT distance on the rectangular and straight paths, whereas the 2'6MWT distance explained 77 and 96%. Adding the Berg Balance Scale and Fugl-Meyer Assessment for the lower extremity substantially improved the 2'6MWT model on rectangular path (Δ R2 = 0.15), with minimal changes elsewhere (Δ R2 = 0.008-0.011). These findings suggest that both the 2MWT and 2'6MWT may serve as reliable and valid measures of walking endurance. However, the strength of association varied by walking path configuration, with reduced explanatory power for the 2'6MWT on the rectangular path, suggesting environment-specific influences on performance. Accordingly, interpretation of these endurance tests should account for walking path configuration and dimensions, which should be routinely reported.","PeriodicalId":14301,"journal":{"name":"International Journal of Rehabilitation Research","volume":" ","pages":"206-213"},"PeriodicalIF":1.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148030513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
