Design outcomes

Primary

MeasureTime frame
Elastic and architectural properties of muscles and tendons in children with upper limb spastic cerebral palsy measured using ultrasound before the start of intramuscular botulinum toxin type A (BTX-A) injections, between 3 weeks and 3 months after treatment and at least 6 months after treatment

Secondary

MeasureTime frame
Muscle activity during the Modified Ashworth scale test measured using electromyography sensors placed on the upper limb before intramuscular BTX-A injections, between 3 weeks and 3 months after treatment and at least 6 months after treatment
