Which of the following measures is used to assess the performance of upper limbs in Duchenne muscular dystrophy?

The Egen Klassifikation scale is specifically designed to evaluate the functional performance of the upper limbs in individuals with Duchenne muscular dystrophy (DMD). This scale focuses on activities of daily living and assesses various aspects of upper limb function, which is crucial for understanding how the disease affects motor abilities in affected individuals.

In contrast, the Vignos functional scale primarily assesses the mobility and overall functional ability of individuals with DMD, but does not specifically target the upper limbs. The Mann Assessment of Swallowing Ability is concerned with swallowing function, which is not relevant to upper limb performance. Additionally, the Brunnstrom stages of motor recovery are related to assessing recovery stages after stroke or central nervous system injuries, rather than muscular dystrophies. Each of these alternative measures serves different purposes and does not provide the specific focus on upper limb function that the Egen Klassifikation scale offers.
