Rev. Assoc. Med. Bras. [online]. 2006, vol.52, n.5, pp. 347-351. ISSN 0104-4230.  http://dx.doi.org/10.1590/S0104-42302006000500024.

OBJECTIVE: To validate a Portuguese version of the EK scale (Egen Klassifikation), that was developed in Denmark for patients with Duchenne muscular dystrophy, and spinal muscular atrophy. METHODS: An English version of the EK scale was translated into the Portuguese language as spoken in Brazil. This scale was applied to 26 male patients (mean age = 12.7 ± 4.0 years) with Duchenne muscular dystrophy. Patients also answered questions of a Portuguese version of the Barthel index questionnaire, and had their right and left hand grip forces measured with a dynamometer. RESULTS: The mean total EK scale score was 8.1 ± 7.3 and the Barthel index 54.0 ± 26.2. The mean hand grip force was 12.7 ± 17.2 % predicted for the right hand, and 14.6 ± 19.8 % predicted for the left hand. The EK scale scores showed highly significant statistical correlations with age (r= 0.596, p= 0.0013), right hand grip force (r= -0.556, p= 0.0032), left hand grip force (r= -0.623, p=0.0007), and Barthel index (r= -0.928, p < 0.0001). CONCLUSION: This translated Portuguese version of the EK scale is an adequate tool to be used for Brazilian Duchenne muscular dystrophy patients.
