Distribution of weakness in the upper and lower limbs post-stroke.

OBJECTIVE: To assess the distribution of weakness in the upper and lower limbs post-stroke and the factors associated with weakness. METHOD: The design was a prospective cross-sectional survey. A consecutive sample of 75 patients (37 (49%) men, mean age 71.5 (SD 12.2) years, 46 (61%) left hemiplegics) with a first-time anterior-circulation stroke, tested 2 - 4 weeks post-stroke, were recruited from two NHS trusts. MAIN OUTCOME MEASURES: Weakness (Motricity Index, MI). RESULTS: Mean MI score was 58.5 (SD 39.6) and 69.1 (SD 33.6) for the upper and lower limb (p < 0.001), but examination of individual data indicated 36 (48%) had no/ negligible difference (0 +/- 9 points) in MI score between the limbs. When there was a difference, the lower limb was more frequently the stronger. There was no significant difference between the proximal and distal joints in either limb (p < 0.217 and 0.410). Severity of weakness was not associated with the subjects' demographics or stroke pathology, but was associated with neglect and sensation. CONCLUSIONS: Although group analysis showed that the leg was significantly stronger than the arm, individual analysis showed that most participants had a similar degree of weakness in both limbs. When there was a difference, the lower limb was more frequently the stronger. Proximal joints were not more severely affected than distal joints. Patient demographics and stroke pathology factors were not associated with weakness, but stroke-related impairments were.

Balance disability after stroke.

BACKGROUND AND PURPOSE: Balance disability is common after stroke, but there is little detailed information about it. The aims of this study were to investigate the frequency of balance disability; to characterize different levels of disability; and to identify demographics, stroke pathology factors, and impairments associated with balance disability. SUBJECTS: The subjects studied were 75 people with a first-time anterior circulation stroke; 37 subjects were men, the mean age was 71.5 years (SD=12.2), and 46 subjects (61%) had left hemiplegia. METHODS: Prospective hospital-based cross-sectional surveys were carried out in 2 British National Health Service trusts. The subjects' stroke pathology, demographics, balance disability, function, and neurologic impairments were recorded in a single testing session 2 to 4 weeks after stroke. RESULTS: A total of 83% of the subjects (n=62) had a balance disability; of these, 17 (27%) could sit but not stand, 25 (40%) could stand but not step, and 20 (33%) could step and walk but still had limited balance. Subjects with the most severe balance disability had more severe strokes, impairments, and disabilities. Weakness and sensation were associated with balance disability. Subject demographics, stroke pathology, and visuospatial neglect were not associated with balance disability. DISCUSSION AND CONCLUSION: Subjects with the most severe balance disability had the most severe strokes, impairments, and disabilities. Subject demographics, stroke pathology, and visuospatial neglect were not associated with balance disability.
