OBJECTIVE:To perform linguistic and cultural adaptation of the Fugl-Meyer Assessment of Physical Performance.MATERIALS AND METHODS:The study for assessment of psychometric properties included 53 post-stroke patients with neurological deficit presented by hemiparesis of different severity. The patients were assessed twice: at admission and after 14 days of treatment and rehabilitation procedures. The Russian version of the Fugl-Meyer Assessment of Physical Performance was developed with consideration of language and cultural characteristics.RESULTS AND CONCLUSION:Results of assessment of psychometric properties of the Russian-language version show its high validity, reliability and sensitivity. The developed Russian-language version of Fugl-Meyer Assessment of Physical Performance is recommended for using by neurologists and rehabilitation specialists both in everyday clinical practice and in clinical studies of patients with post-stroke paresis. The results obtained in the study show necessity for pre-training of specialists who perform assessment of patients with post-stroke paresis using the Fugl-Meyer Assessment of Physical Performance.

Objective: linguistic and cultural adaptation of the original version of Berg Balance Scale (BBS) and assessment its psychometric properties.Patients and methods. The staff of the Validation Center of International Scales and Questionnaires of the Research Center of Neurology received consent from Katherine Berg to validate the BSS in Russia. We carried out the linguocultural ratification during the validation study and prepared a Russian version of the scale. To assess the psychometric properties of the scale (reliability, validity, and sensitivity), we evaluated 55 patients (30 females and 25 males) aged 22–88 years with different neurological disorders (vascular and demyelinating diseases of the central nervous system, peripheral neuropathy, and movement disorders). We analyzed the differences of the total BBS score and the number of patients with high and low risk of falls at the end of rehabilitation compared to baseline to assess the dynamics of changes.Results and discussion. We successfully performed the translation and linguocultural adaptation of the BBS. The scale represents a high level of validity (expert score: 8.6 out of 10 points), reliability (Pearson's correlation coefficient r=0.98, р<0.0001; Cronbach's alpha α=0.94 р<0.001; Cohen's kappa κ=0.71, p<0.0001) and sensitivity (р<0.0001). After a two-week rehabilitation course, the risk of falls significantly decreased (χ2 =4.42; р=0.035); however, the level of independence of movement did not change significantly (F=0.94; р=0.636).Conclusion. The Russian version of the BBS was officially adapted based on the results of the accomplished validation study and is recommended for use both in routine clinical practice and in clinical trials by neurologists and rehabilitologists. The scale is available for downloading by QR code and on the website of Validation Center of International Scales and Questionnaires of the Research Center of Neurology.

Objective: to develop a Russian version of the modified Rankin Scale (mRS) and to assess its psychometric properties.Patients and methods. The investigation involved 50 patients (25 women, 25 men) over 18 years of age (mean age, 56 years) with an acute cerebrovascular accident diagnosis. During the validation procedure, the authors carried out the linguocultural ratification of mRS, prepared its Russian-language version, and then assessed its psychometric properties (reliability, sensitivity, validity).Results and discussion. Translation and linguistic adaptation of mRS was successfully completed. The results obtained in assessing the psychometric properties of the developed Russian version of the scale reflect its high reliability and the valid and reliable indicators of its sensitivity. A statistical study of constructive and content validity also determined the high significance of differences.Conclusion. The investigation has resulted in the official Russian version of mRS, which is recommended for use by neurologists and rehabilitation specialists in both daily clinical practice and in clinical trials.
