22. European Stroke Conference 839 Rehabilitation and reorganisation after stroke Is the symmetry of double support phase a good predictor of gait speed recovery in subjects with stroke? M.C.

Following a stroke, DS of the affected lower limb (the time spent during weight transference to the affected lower limb) tends to be increased. However, little is known about the DS of the non-affected lower limb. Therefore, the symmetry between DS of both lower limbs (DS symmetry) in subjects with stroke is unknown as its impact on gait. This study aimed to explore the DS symmetry and explore its role on gait speed re-covery. 790 © 2013 S. Karger AG, Basel Scientific Programme Subjects less than 3 months after stroke were recruited and assessed as soon as they were able to walk independently or with human assistance (T1) and again 6 months after stroke (T2). Time spent in the DS phase was assessed through a video-recording in the sagittal plane whilst patients walked along a 5 meter corridor, at their preferred speed. Gait speed recovery was assessed performing the 5-meter walk test (5MWT), at patients’ maximum speed. Three trials were performed for each pa-rameter. The DS symmetry (DS-SI) was calculated using the formula proposed by Robinson et al. (1987) (perfect symmetry =0). Descriptive statistics, the non-parametric Wilcoxon test and a linear regression were used. Fifteen patients (8 men) with a mean age of 66.0±13.3 years old and a BMI of 25.3±2.3Kg/m2 participated. The DS-SI was not significantly different between T1 and T2 (T1=28.1±27.4 vs T2=37.18±35.47; p=0.233). However, the time that patients spent performing the 5MWT decreased significantly (T1=20.40±14.58 vs T2=11.82±13.57; p=0.006). The DS-SI was not related to gait speed at T1 (R2=0.007; p=0.767) but it explained 55.2% of gait speed recovery at T2 (R2=0.552; p=0.033). These preliminary results showed that the DS-SI was not a good predictor of gait speed recovery in stroke acute stage (T1); however, it may be a predictor at the beginning of stroke chronic stage (T2-beyond 6 months). 840 Rehabilitation and reorganisation after stroke Prevalence of Cognitive impairments in young stroke patients attending Stroke Rehabilitation unit D. KAUR1, G. KUMAR2, A.K. Singh3 Bihar Neurodiagnostic Centre, PATNA, INDIA1, Bihar Neurodiagnostic Centre, PATNA, IN-DIA2, Bihar Neurodiagnostic Centre, PATNA, INDIA3 Background: In India, the prevalence of stroke in younger individuals is high as compared to high-income countries. Such events occurring at a productive age group assume importance. One of the most common problems faced during rehabilitation of the patient in stroke units is poor compliance to exercises due to cognitive losses. Unfortunately cognitive assessment still remain undervalued in routine clinical examination as these impairments are less instantaneously obvious than the hemiplegia or other gross physical handicaps. Montreal Cognitive assessment (MoCA) is a 10-minute, 30-point test, which covers a wide range of cognitive abilities such as visuospatial skills, naming, memory, fluency, attention, abstraction, language and orientation. The objective of this study was to identify the prevalence of cognitive impairments among young stroke patients attending rehabilitation sessions 3 months post stroke. Methods: The data comes from a random sample, drawn from a stroke rehabilitation unit. All the 30 right handed patients and a sample of 50 healthy subjects, matched for age, dexterity and educational years were administered Hindi version of MoCA. Only those subjects were included who were younger than 55 years of age, had no visual problem and were able to write with right dominant hand post stroke. Results: An independent sam-ple t-test was conducted to compare the MoCA scores: 16.96 ± 3.81 of Group A comprising 30 of stroke patients with mean age of 43.4±6.93 and having 15.2 ± 1.90 years of education with group B, scoring 25.72 ± 1.62, mean age was 44.24 ± 6.57and had 16.24 ± 2.18 years of education. There was a significant difference in the scores of Hindi version of MoCA scores in both the groups (p<.0001), suggesting stroke patients had mild cognitive impairment. Conclusion: The findings from this study suggest that patients post stroke suffer from varying degree of cognitive impairments. It is impera-tive to undertake quick screening of these functions before starting any rehabilitation programme. MoCA requires no formal training for administration. This study recommends using measures of Cognitive impairments as complimentary to functional assessment.
