Efficacy Research of Bimanual Intensive Training in Children With Hemiplegic Cerebral Palsy

The subtest 3 of the Bruininks-Oseretsky Test(BOT-2), manual dexterity (MD), will be used to assess a child's upper limb dexterity. The subtests 3 of the BOT-2 consist of 5 goal-directed activities that involve reaching, grasping, and bimanual coordination with small objects to investigate a child's upper limb manual function.Higher scores mean a better outcome.

The Box and Block test (BBT) assesses manual dexterity by county the number of blocks that are transferred with a single hand from one compartment to another within 60 seconds.Higher scores mean a better outcome.

Three-dimensional marker trajectory data will be measured using a motion analysis system (Vicon MX, Oxford Metrics Group, U.K.). Twenty-eight passive infrared retroreflective markers will be attached to the skin of the body segments to track the motion of the body segments. For the performance outcome measures, endpoint variables during reach-to-grasp task, namely reaction time, movement time, movement unit, peak velocity and its time percentage during the movement time will be calculated using the wrist marker. For the performance production measures, joint angles of the shoulder, elbow and wrist during reach-to-grasp task will also be calculated to represent the motor strategy of children with CP before and after intervention.

The Pediatric Motor Activity Log-Revised(PMAL-R) is a parent-reported evaluative tool used to capture the spontaneous use of the affected upper limb in 22 daily activities. Each activity is rated by parents/careers on two set (how often and how well) of 6-point ordinal scales (0-5). The 'how often' scale measures amount of use, and the 'how well' scale measures quality of movement, of the affected upper limb.Higher scores mean a better outcome.

The ABILHAND-Kids questionnaire is a Rasch-based assessment that measures children's perceived difficulty in performing ADL that require the use of the bilateral upper limbs. It contains 21 items measuring manual ability and is rated on a 3-point response scale(0-2). The parent is asked to fill in the questionnaire by estimating their child's ease or difficulty in performing each activity, irrespective of the limb(s) the child actually use and whatever the strategies used to perform the activity.Higher scores mean a better outcome .

The Pediatric Evaluation of Disability Inventory(PEDI) is a parent-reported questionnaire. It contains two subscales :(1)functional skill scale (2)caregiver assistance scale. The parent is asked to fill in the questionnaire by estimating their child's performance capability in 197 items in three domains :(1)self-care (2)mobility (3)social is rated on a 2-point response scale(0-1). In caregiver assistance scale, the needs of caregiver assistance to complete each activity are scored from 0 to 5 point.Higher scores mean a better outcome in both parts .

The Parenting Stress Index-Short Form(PSI-SF) is direct derivative from the Parenting Stress Index (PSI) full-length test which was created to sample a diverse range of potential influences on parenting practices to address the need for a psychometrically sound but brief screening measure of parenting stress. All 36 items of the PSI-SF consist of three subscales: Parental Distress, Parent-Child Dysfunctional Interaction, and Difficult Child. Each subscale consists of 12 items rated from 1 (strongly disagree) to 5 (strongly agree). High scores on the subscale and PSI-SF total score indicate greater level of stress
