This is a Phase III clinical trial to compare the efficacy of two dosages of a new infant rehabilitation protocol - I-ACQUIRE - to usual and customary forms of infant rehabilitation in infants who experienced Perinatal Arterial Stroke (PAS).


Perinatal Stroke, Hemiparesis

Recruitment Status


Detailed Description

The proposed study is a Phase III trial powered to determine efficacy of two different doses of I-ACQUIRE for children 8 to 36 months old with PAS and hemiparesis. The design is a prospective Randomized Controlled Trial (RCT) in which 240 children will be randomly assigned to one of 3 treatment groups (N=80 per group): 1) Moderate Dose I-ACQUIRE (3 hrs/day, 5 day/wk X 4 wks), 2) High Dose I-ACQUIRE (6hrs/day, 5 days/wk X 4 wks), or 3) Usual and Customary Treatment (U&CT). I-ACQUIRE will be delivered by protocol-trained therapists and monitored weekly for dosage and treatment fidelity; U&CT will be provided by community therapists with dosage and approaches documented weekly. All primary and secondary efficacy outcomes rely on blinded assessments at baseline, end of treatment, and 6 mos post-treatment. Exploratory outcomes and supplemental clinical measures may provide valuable additional data about development and health in this sample of children with PAS.
