Cross-cultural adaptation and validation of the mozambican version of the Stroke Rehabilitation Assessment of Movement

Abstract

Introduction: The use of standardized and reliable measuring instruments is a prerequisite for good practice in Physical Therapy and allows monitoring the results of the intervention and claiming scientific credibility for the profession. The Stroke Rehabilitation Assessment of Movement (STREAM) is an instrument widely used in the evaluation of limitations in terms of voluntary movement and basic mobility in patients with sequelae of Stroke. Objective: Contribute to the
cross-cultural adaptation and validation of the Portuguese version of STREAM to the Mozambican cultural and linguistic context. Materials and Methods: Two samples were used which included: 1) 9 experts analyzed the content validity; 2) 70 patients with stroke sequelae, selected by convenience- from Nampula Central Hospital (NCH) and Mavalane General Hospital (MGH) were submitted to the application of the STREAM scale by 6 independent observers, in order to analyze the reliability of the instrument. Results: The Mozambican version of STREAM revealed for content validity an absolute consensus (100%) among the elements of the experts’ panel. For inter-observer reliability, the Intraclass correlation coefficient (ICC) values indicated a perfect agreement index, with ICC values ranging from 0.980-0.993 in HCN and 0.980- 1,000 in HGM and good internal consistency with Cronbach's alpha values of 0.904-0.998 in HCN between 0.881-1.000 in HGM for each of the 3 subscales and for the total scale. Conclusion: The Mozambican version of the STREAM scale proved to be valid and reliable in the psychometric properties investigated. Future studies are suggested to reinforce our results.
