P 522. Measuring Grip and Finger Flexion Strength in Children and Adolescents with Neuromuscular Disorders

Background: The principal characteristic of a genetically determined neuromuscular disorder is weakness in the proximal and/or distal musculature. There are various clinical testing methods for establishing muscular strength and function in cases of neuromuscular disorders. A majority of the available measuring methods are based on the measurement of strength in the lower extremities. There are few tests available for determining the loss of strength in the upper extremities.
