〔Abstract〕 Objective To investigate the effects of Hand-Arm Bimanual Intensive Training (HABIT) based on the FITT-CORRECT principles on upper limb function and functional independence in children with spastic hemiplegic cerebral palsy. Methods A total of 87 children with spastic hemiplegia were enrolled and randomly divided into an observation group (n=44), which received HABIT based on the FITT-CORRECT principles, and a control group (n=43), which received conventional HABIT. Both groups received intervention for 6 weeks. The Quality of Upper Extremity Skills Test (QUEST), Peabody Developmental Motor Scales–Fine Motor (PDMS-FM), and the Functional Independence Measure for Children (WeeFIM) were administered before and after treatment. The root mean square (RMS) values of the biceps and triceps brachii during maximum isometric contraction of elbow flexion and extension on the affected side were also measured. Results Before treatment, there were no significant differences between the two groups in QUEST, PDMS-FM, WeeFIM scores, or RMS values of the biceps and triceps during maximum isometric contraction of the affected elbow (P>0.05). After 6 weeks of treatment, no significant change was observed in the RMS values of the triceps during elbow flexion in either group (P>0.05). All other outcome measures improved significantly in both groups (P<0.05). The observation group showed significantly greater improvements in dissociated movement and grasp scores of QUEST, grasp and visual-motor integration scores of PDMS-FM, WeeFIM scores, as well as RMS values of the biceps during elbow flexion and both the biceps and triceps during elbow extension on the affected side (P<0.05). Conclusion Compared with conventional HABIT, HABIT based on the FITT-CORRECT principles is more effective in improving upper limb function and functional independence in children with spastic hemiplegia.
