Subacute ischemic stroke rehabilitation outcomes in working-age adults: The role of aphasia in cognitive functional independence

The cutoff values of functional independence measure scores for predicting discharge destination in the early stroke phase

This study aimed to determine cutoff values of functional independence measure (FIM) scores to predict the discharge destinations of patients with acute stroke. The sample included 318 patients with acute stroke (mean age, 72.0 years; women, 39%). The discharge destination was categorized into three groups: home, postacute rehabilitation (hospital with convalescent rehabilitation wards), and postacute care (institution without convalescent rehabilitation wards). We assessed FIM after lifting bed restriction. Multinomial logistic regression analyses were used to estimate odds ratios (OR) and 95% confidence intervals (CI) of the FIM scores for predicting discharge destinations, with postacute rehabilitation as a reference. Cutoff values of motor and cognitive FIM scores for distinguishing home from postacute rehabilitation and postacute care from postacute rehabilitation were determined using receiver operating characteristic curves. The proportion of home, postacute rehabilitation, and postacute care were 34.6%, 41.8%, and 23.6%, respectively. After adjustments for clinical variables, the ORs (95% CIs) for motor and cognitive FIM scores for home versus postacute rehabilitation were 1.08 (1.04-1.11) and 1.05 (0.98-1.12). Furthermore, those for postacute care versus postacute rehabilitation were 1.01 (0.98-1.04) and 0.92 (0.87-0.98). The cutoff values of the motor and cognitive FIM scores for distinguishing home from postacute rehabilitation were 37.5 (sensitivity: 0.92; specificity: 0.64) and 23.5 (sensitivity: 0.78; specificity: 0.67). Furthermore, those for distinguishing postacute care from postacute rehabilitation were 15.5 (sensitivity, 0.81; specificity, 0.51) and 12.5 (sensitivity, 0.74; specificity, 0.64). The identified cutoff values may serve as early indicators for predicting discharge destinations from acute stroke care.

Meta-analysis and systematic review of the relationship between sex and the risk or incidence of poststroke aphasia and its types

OBJECTIVE

To analyse and discuss the association of gender differences with the risk and incidence of poststroke aphasia (PSA) and its types, and to provide evidence-based guidance for the prevention and treatment of poststroke aphasia in clinical practice.

DATA SOURCES

Embase, PubMed, Cochrane Library and Web of Science were searched from January 1, 2002, to December 1, 2023.

STUDY SELECTION

Including the total number of strokes, aphasia, the number of different sexes or the number of PSA corresponding to different sex.

DATA EXTRACTION

Studies with missing data, aphasia caused by nonstroke and noncompliance with the requirements of literature types were excluded.

DATA SYNTHESIS

36 papers were included, from 19 countries. The analysis of 168,259 patients with stroke and 31,058 patients with PSA showed that the risk of PSA was 1.23 times higher in female than in male (OR = 1.23, 95% CI = 1.19-1.29, P < 0.001), with a prevalence of PSA of 31% in men and 36% in women, and an overall prevalence of 34% (P < 0.001). Analysis of the risk of the different types of aphasia in 1,048 patients with PSA showed a high risk in females for global, broca and Wenicke aphasia, and a high risk in males for anomic, conductive and transcortical aphasia, which was not statistically significant by meta-analysis. The incidence of global aphasia (males vs. females, 29% vs. 32%) and broca aphasia (17% vs 19%) were higher in females, and anomic aphasia (19% vs 14%) was higher in males, which was statistically significant (P < 0.05).

CONCLUSIONS

There are gender differences in the incidence and types of PSA. The risk of PSA in female is higher than that in male.

A Comparative Analysis of Functional Status and Mobility in Stroke Patients with and without Aphasia

All researchers agree that aphasia is a serious consequence of a stroke, but they also report contradictory data regarding the functional outcome. The aim of this study was, therefore, to assess the functional outcomes of stroke patients with and without aphasia, who were undertaking a regular rehabilitation programme.

MATERIALS AND METHODS

The study group consisted of 116 post-stroke patients, including 54 patients without aphasia (G1) and 62 patients with aphasia (G2). The following tests were used before (T1) and after (T2) rehabilitation measurement points: Barthel Index (BI), Sitting Assessment Scale (SAS), Berg Balance Scale (BBS), Trunk Control Test (TCT), Test Up & Go (TUG) and the Timed Walk Test (TWT).

RESULTS

The group of post-stroke patients with aphasia had a significantly longer time since a stroke on admission, a significantly longer length of stay in the ward and significantly worse SAS and TCT scores at T2, compared to patients without aphasia. Both groups achieved significant improvement in all studied parameters (SAS, TCT, BI, BBS, TUG and TWT). Aphasia was a predictor of functional status in the stroke patients group, but only at the time of admission to the ward.

CONCLUSIONS

Patients with and without aphasia have an equal likelihood of improving their functional status and returning to independence. Aphasia should not be an absolute factor that excludes stroke patients from research studies on their functional status.
