NEWHAM3 KING’S COLLEGE LONDON AND NIHR/GUY’S AND ST THOMAS’ NHS FOUNDATION TRUST/KCL BIOMEDICAL RESEARCH CENTRE, LONDON, UNITED KINGDOM1, UNIVERSITY COLLEGE LONDON, LONDON, UNITED KINGDOM2, KING’S COLLEGE LONDON, LONDON, UNITED KINGDOM3 Background: The KayPentax Digital Swallowing Workstation™ (DSW) is used to provide surface electromyography (sEMG) biofeedback during dysphagia rehabilitation with stroke patients. How-ever, the system does not display the raw signal and the methods of automatic signal processing are unclear. Therefore it is not known if sEMG amplitude measurement by the DSW is accurate. The aim of the study was to compare the sEMG measurements recorded with the DSW against a stan-dard sEMG system to determine concurrent validity. Methods: To enable simultaneous sEMG mea-surement and assessment of force, sEMG amplitude data was collected from the right biceps brachii muscle with both the DSW and the Delsys Bagoli-4 Desktop EMG System during isometric elbow flexion. Force was measured with a dynamometer. Fifteen healthy volunteers (10 female), mean age 34.78 yrs (SD 10.37) performed maximum voluntary contractions (MVC) and contractions at 5-90% of the MVC. Normalised sEMG amplitudes measured by each system for each contraction were compared with Bland-Altman plots and regression analysis. Results: There was a linear relationship between the amplitude measured by both systems (r2 =0.847, Standard Error of estimate 11.031). Bland-Altman plots of the data revealed the mean difference between the two methods was -0.025 (SD 11.084) with limits of agreement −21.750 - 21.701 (normalised volts). Conclusion: The DSW provides valid measurements of sEMG amplitude as indicated by an acceptable level of agreement with a reference sEMG system. This implies it can provide accurate biofeedback for dysphagia ther-apy. The effects of fatigue and weakness on the DSW sEMG signal remain to be tested and studies using this system are limited by having no access to the raw signal. 849 Rehabilitation and reorganisation after stroke New clinical nutrition suporting concept for rehabilitation and reorganisation process after stroke.

Protein-calorie malnutrition is a significant clinical problem directly complicat-ing treatment and rehabilitation process, including systemic therapy of patients hospitalized after stroke in clinical stroke rehabilitation units. Often in this group it is also reported lower number of biochemical parameters related to insufficient coverage of the patients energy needs. The aim of our work was to evaluate and determine nutritional needs of the patient’s hospitalized after stroke with complex assesment of integrated targeted nutritional program used in this group. Material and meth-ods: We examinated and analyzed a group of 50 patients hospitalized after miscellaneous types of stroke, in the year 2012 in Ludwik Rydygiers Collegium Medicum in Bydgoszcz, Nicolaus Coper-nicus University in Toruń - university clinical stroke rehabilitation unit. Local ethical comitee permisssion was obtained. In this study, at first in the time of patient admission to the clinic, after standard medical interview and important data collection we have measured 4 nutritional status pa-rameters: BMI based on weigh and hight, WHR based on waist and hip circumference, measurement of skinfolds and the level of serum albumin and total lymph count in blood samples. All tests were repeated after six-month observation period related to the implementation of various rehabilitation and nutrition programs in this same group of patients. We have selected to the assesment 3 types of nutritional programs.Results: In our study we indicated a significant difference correlated with the effects of rehabilitation and nutrition status undertaken depending on the choosen nutrition program. The group of patients basic diet is not balanced pointed to poor resultsConclussion:Proper nutrition has a significant impact on patients clinical status and rehabilitation progress in the 6-month observation period. Perhaps clin-ical nutrition could be an important component in secondary stroke prevention programs and could improve patients future prognostic factors and quality of live.
