Spanish-language Translation, Cross-cultural Adaption and Evaluation of the Psychometric Properties of Two Upper Limb Assessment Scales in People with Sequelae of Stroke in Chronic Phase
The purpose of this cross-sectional study is to translate and cross-culturally adapt to Spanish the Motor Evaluation Scale for Upper Extremity in Stroke Patients (MESUPES) and the Stroke Upper Limb Capacity Scale (SULCS) and to assess their psychometric properties in Spanish people with chronic stroke.
Stroke is the second cause of mortality and the first cause of acquired disability in Spain. In the coming years, due to the progressive ageing of the European population, the incidence of this disease is expected to increase. Current epidemiological studies estimate that one out of six people are likely to suffer a stroke during their lifetime in Spain.
The sequelae from stroke are very varied, with hemiparesis being one of the most commonly observed. The involvement of the upper limb is frequent in people with this sequela in the acute phase, affecting to 70% of them approximately, with the limitations that this can cause. It is therefore necessary to have instruments that quantify these functional changes and that must be sensitive, reliable and valid tools. These would allow treatment goals to be set, interventions to be planned and results to be recorded to determine effectiveness in an appropriate way.
Several scales are currently available to assess functional impairment of the upper extremity (UE) after stroke. For example, the Stroke Upper Limb Capacity Scale (SULCS) was developed with the idea of being a simple to use and unidimensional instrument to assess this population. It was the first scale that included simple functions items (minimal hand use) and highly demands manipulative items. Similarly, the Motor Evaluation Scale for Upper Extremity in Stroke Patients (MESUPES) quickly assesses quantity and quality of movement in the UE after stroke, and can be used to assess people with no muscle activation and still be sensitive to assess people with minimal motor impairment.
On the other hand, the linguistic and cultural adaptation of health assessment instruments is becoming necessary, given the increase of multinational research. Moreover, in countries with a multicultural population, this factor needs to be taken into account as it can have a direct effect on the measures recorded. The quality of healthcare is highly dependent on an accurate assessment process, which in turn will depend on an understanding of the cultural, linguistic and ethical context of each individual. Due to the increasingly diversified world population caused by globalisation, this need is increasing. The process of translating, adapting and validating a scale requires very rigorous planning and methodology so that a reliable and valid measure can be obtained for the target population.
The aim of this study is two-fold: first, to translate and cross-culturally adapt to Spanish the "Motor Evaluation Scale for Upper Extremity in Stroke Patients (MESUPES)" and the "Stroke Upper Limb Capacity Scale (SULCS)"; and second to assess the psychometric properties of the Spanish versions of both scales in Spanish people with chronic stroke.
To cope with the study objectives, first, the translation and cross-culturally adaptation to Spanish of both scales was performed following the international recommendations. Next, a cross-sectional and psychometric study will be carried out. Participants will be assessed in two day visits (baseline and re-test), with no less than one week and no more than two weeks between them. In both visits, the two target scales will be performed. Additionally, in the first appointment, clinical, demographic and anthropometric data and cognitive function will be collected, and questionnaires and clinical tests will be carried out to study the reliability and validity of the target scales.
