Importance: Clinical practice guidelines for infants at high risk of cerebral palsy (CP) emphasize the importance of very early and intensive intervention.
Objective: To determine the feasibility of a new, home-based, early intensive bimanual stimulation program (BB-Bim) and its impact on hand function in infants at risk of unilateral CP.
Design: Single case experimental design, multiple baseline across subjects, lasting from 12 to 15 wk, including a 4- to 7-wk randomized baseline, followed by 8 wk of BB-Bim.
Setting: Home.
Participants: Infants (ages 3-12 mo) with suspected unilateral CP, whose parents agreed to participate in the stimulation program.
Intervention: Parent-provided bimanual stimulation 20 min/day, 6×/wk, with weekly occupational therapist coaching visits.
Measures: Weekly repeated measures were the Hand Assessment in Infants (HAI) and Goal Attainment Scaling (GAS). Feasibility and relevance were assessed with a logbook and a parental report, including 10 continuous 0-10 scaled questions.
Results: Six infants were included (2 with left and 4 with right brain lesions). Parents provided a mean 3.4 to 6.2 stimulation sessions/wk. Feasibility and relevance were highly rated (Ms = 8.2-9.6, SDs = 0.2-1.3). Stimulation significantly improved HAI bimanual and total scores for all infants, with no impact on HAI unilateral scores. GAS scores improved with stimulation (significant for 3 infants).
Conclusions and relevance: BB-Bim was feasible and tended to improve bimanual function in infants at risk of unilateral CP. What This Article Adds: Parent-provided daily bimanual stimulation at home is feasible when parents are coached weekly by an occupational therapist. Bimanual stimulation seems to improve functional interactions between the hands among infants at high risk of unilateral CP.
