Background and Purpose-The goal of this study was to assess the specific influence of stroke etiology on rehabilitation results. Methods-This was a case-control study of 270 inpatients with sequelae of first stroke who were enrolled in homogeneous subgroups and matched for stroke severity, basal disability, age (within 1 year), sex, and onset admission interval (within 3 days) who were different only in terms of stroke origin, infarction versus hemorrhage. We compared the groups' length of stay, efficiency and effectiveness of treatment, and percentage of low and high responder patients. Odds ratios of dropouts and of low and high therapeutic response were also quantified. Results-Compared with ischemic patients, hemorrhagic patients had significantly higher Canadian Neurological Scale and Rivermead Mobility Index scores at discharge; higher effectiveness and efficiency on the Canadian Neurological Scale, Barthel Index, and Rivermead Mobility Index; and a higher percentage of high responders on the Barthel Index. Hemorrhagic patients showed a probability of a high therapeutic response on the Barthel Index that was Ϸ2.5 times greater than that of ischemic patients (odds ratio, 2.48; 95% confidence interval, 1.19 to 5.20; accuracy on prediction, 87.06%). Conclusions-The

Background and Purpose-We sought to assess the specific influence of sex on rehabilitation results. Methods-A case-control study in 440 consecutive patients with sequelae of first ischemic stroke were enrolled in 2 subgroups (males and females) and matched for severity of stroke (evaluated by means of the Canadian Neurological Scale), age (within 1 year), and onset-admission interval (within 3 days). Functional data, evaluated by means of the Barthel Index and the Rivermead Mobility Index, were compared between subgroups. Logistic regressions were used to clarify the role of sex in affecting global autonomy and mobility. Results-After rehabilitation treatment, a sex-related difference was observed essentially in the higher levels of response.Indeed, more men than women reached independence in both stair climbing and activities of daily living (ADL), with a higher response and effectiveness on mobility. In multivariate analyses, male patients had a 3 times higher probability than female patients of good autonomy in both stair climbing and ADL (odds ratio

The analysis of upper-body acceleration is a promising and simple technique to quantitatively assess dynamic gait stability. However, this method has rarely been used for people with stroke, probably because of some technical issues still not addressed. We evaluated the root-mean-square (RMS) and harmonic ratio of trunk accelerations for a group of 15 inpatients with subacute stroke who were able to walk (61.4 +/-14.9 yr) and compared them with those of an age-matched group of nondisabled subjects (65.1 +/-8.8 yr) and those of a highly functional group of young nondisabled subjects (29.0 +/-5.0 yr). Small (<2%) but significant (p < 0.03) differences were found in RMS values obtained by applying the two most common computational approaches: (1) averaging among individual-stride RMS values and (2) computing the RMS value over the entire walking trial without stride partitioning. We found that the intersubject dependency of acceleration RMS values by selected walking speed was specific for each group and for each of the three body axes. The analysis of ratios between these three accelerations provided informative outcomes correlated with clinical scores and not affected by walking speed. Our findings are an important step toward transferring accelerometry from human movement analysis laboratories to clinical settings.Abbreviations: ANOVA = analysis of variance, AP = anteroposterior, BI = Barthel Index, CC = craniocaudal, FAC = Functional Ambulatory Classification, HFG = high functional group, HR = harmonic ratio, ICC = intraclass correlation coefficient, LFG = low functional group, LL = laterolateral, MFG = medium functional group, RMI = Rivermead Mobility Index, RMS = root-mean-square, RMS AP = RMS value along AP axis, RMS CC = RMS value along CC axis, RMS LL = RMS value along LL axis, RMS mean = RMS value obtained averaging individual-stride RMS values, RMS overall = RMS value obtained over the entire walking trial without stride partitioning, WS = walking speed.
