Brief summary
Hand-Arm Bimanual Intensive Training (HABIT) has been shown to result in improvements in hand function and daily functioning of children with unilateral cerebral palsy (CP). Children with bilateral CP may also present difficulties to coordinate their hands to perform activities. Thus, HABIT may be a potential intervention for these individuals. We intend to examine the effects of HABIT on hand function and daily functioning of children with bilateral CP compared with conventional occupational therapy (OT). Our hypothesis is that children receiving HABIT will present larger improvements in manual dexterity and daily functioning as compared to conventional OT.
Detailed description
Study Design: Randomized Controlled Trial. Study Participants & Setting: Forty children with bilateral CP recruited from the Associação Mineira de Reabilitação, Belo Horizonte, Brazil. Procedures: After being included in the study, children will be randomly assigned to a intervention group (n=20) or a control group (n=20). Children in the intervention group will receive a 90-hour (6 hours/day; 5 days/week, 3 weeks) of Hand-Arm Bimanual Intensive Training (HABIT) while children in control group will maintain their usual frequency of Occupational Therapy (OT) sessions (45 minutes/session, twice a week, for 3 weeks), focusing on functional training, stretching and sensory stimulation. All participants will be assessed by an examiner blinded to group allocation before and after the intervention period, as well as 6 months after the intervention (follow-up). Statistical Analysis: A 2 (groups) x 3 (assessments) analysis of variance will test the effects of group, assessment and group x assessment interaction with a level of significance set at 0.05.
Interventions
OTHERHABIT
Provision of individualized bimanual activities, individually chosen according to the child´s abilities, impairments and improvements in order to achieve success and to encourage bimanual use. Task difficulty is graded, focusing on enhancing the level of difficulty or speed, according to child's improvements. We use whole task practice (sequencing successive movements in the context of activities), part task practice (practice of specific components of the task in a repetitive sequence of time) and individualized functional goal training.
Children will maintain the occupational therapy sessions with their therapists, without any change in their routine at the rehabilitation center. Strategies such as functional training, stretching and sensory stimulation are used.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Functional goals | 6 months | Canadian Occupational Performance Measure (COPM) - performance and satisfaction scales (each scale ranging 1-10; higher values, better outcomes) |
| Daily functioning | 6 months | Pediatric Evaluation Disability Inventory (PEDI) \[Scales: (1)self-care functional skills : ranging from 0-63; higher values, better outcomes; (2) caregiver assistance in self care: ranging from 0-40; higher values, better outcome\] |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Manual dexterity | 6 months | Jebsen Taylor Test of Hand Function (JTTHF): time to complete 6 hand function activities- score comprises the sum of time to complete the activities; ranging from 0-1080; higher values, worse outcome) |
| Bimanual hand use | 6 months | Both Hand Assessment- score of bimanual hand function: score ranging from 0 to 100% (higher values, better outcome) |
