The Egen Klassifikation Scale version 2 (EK2) is an important functional ability
assessment scale for nonambulant neuromuscular patients. We investigated
the validity and reliability of the EK2 scale in Turkish Duchenne muscular
dystrophy (DMD) and spinal muscular atrophy (SMA) patients. Forty-one
patients were included in the study. An intra/interobserver reliability study
of the EK2 scale as translated into Turkish was performed. The Brooke
Functional Classification Scale (BFC) for Upper and Lower Extremities, 10-item
Modified Barthel’s Index for Activities of Daily Living (MBI), and Pulmonary
Dysfunction Index (PDI) were used to investigate the validity of the Turkish
version of the EK2 scale. Cronbach’s alpha was 0.81 and ICC was 0.87 with
a 95% confidence interval (r=0.92, p<0.01). There were positive, moderate
correlations between the EK2 sum score and the BFC upper extremity level
and between the EK2 sum score and the PDI, and a negative, moderate
correlation between the EK2 sum score and the MBI (p≤0.01). The Turkish
version of the EK2 scale was found to be highly reliable and valid.
