The investigators hypothesize that children with spastic cerebral palsy will show greater improvements in gross motor function, associated developmental skills and growth after the 3 months of myofascial structural integration treatment, a form of deep massage, than they showed after a 3- or 6-month pre-treatment waiting period.

The investigators further hypothesize that children with spastic CP will maintain their gains in gross motor function for ≥ 3 months after completion of MSI treatment.

• The investigators will talk to you by telephone to determine if your child is eligible for the study.
• The study lasts for a total of 12 months with the massage treatment period lasting 12 weeks.
• The study entails a total of 10 sessions of Myofascial Structural Integration therapy over the 12-week period. Each session will last one hour.
• The child will have an evaluation of motor functions and development on enrollment and at three-month intervals for a total of 5 evaluations.

Inclusion Criteria:

• Children from 1 up to, but not including, 7 years of age
• Children having the diagnosis of spastic cerebral palsy
• Children who have spasticity in one or both upper or lower limbs
• Children who are classified as either Gross Motor Function Classification System (GMFCS) level 2, 3 or 4 or Manual Ability Classification System (MACS) level 2, 3, 4 or 5

Exclusion Criteria:

• Children with active seizure disorders
• Children taking more than one medication to control their seizures
• Children with severe health problems that could be exacerbated by the treatment (such as severe chronic lung disease)
• Children who have undergone surgical treatments or botulinum injections within 6 months of entering the study
• Children who have planned surgical interventions during the studies time course
• Children with sensory, cognitive or language deficits which would affect their ability to understand directions necessary for assessment.
