Ultrasound elastography – A pilot study to examine muscle stiffness

Purpose: As an innovative, noninvasive technique ultrasound elastography allows to assess the elasticity of tissue. The aim of this study was to evaluate strain elastography as a reliable method in different groups of muscles; determination of muscle elasticity in young adults at rest and after exercise and to compare the results with data of children. Subsequently, the elasticity of muscles in children with cerebral palsy will be examined before and after the treatment with botulinum toxin A. Material and methods: Elastography of the M. biceps brachii, quadriceps femoris, and gastrocnemius lateralis was obtaine…
