Effectiveness of selective muscle-release surgery for children with cerebral palsy: longitudinal and stratified analysis.

The purpose of this study was to determine the effectiveness of muscle-release surgery for children with cerebral palsy (CP) using longitudinal and stratified analysis. Twenty-five children with CP (15 females, 10 males; age range 4 to 16 years; mean age 8 years 2 months, SD 3 years 2 months) were selected from five treatment centres in Japan. Twenty-two children had spastic diplegia, two had spastic quadriplegia, and one had athetospastic quadriplegia. Motor function for each child was assessed using the Gross Motor Function Measure (GMFM). Assessment was conducted on eight separate occasions: 1 month and 1 week before surgery, and 1, 2, 4, 6, 9, and 12 months after surgery. Participants' motor function before surgery was classified using the Gross Motor Function Classification System (GMFCS). Six children were classified at level I, three at level II, six at level III, and 10 at level IV. A significant difference was found after surgery in the GMFCS levels III and IV groups (p<0.05). Improvement in GMFM scores between 1 week before surgery and 12 months after surgery were 1, 5, 8.5, and 8.5 for GMFCS levels I to IV respectively. Results indicate that this treatment is advantageous for improving motor function in children within GMFCS levels III and IV.

Gross motor function classification system: preliminary study for Japanese children.

OBJECTIVE: The purpose of the study was to produce a version of the Gross Motor Function Classification System with the same construct as the original one that would be applicable to Japanese children with cerebral palsy. DESIGN: The reliability studies were performed twice with a convenience sample (first study, 76 children with cerebral palsy; second study, 225 children with cerebral palsy). The first version of the translated Gross Motor Function Classification System was used in the first reliability study. It was revised based on the findings of the study and used in the second reliability study. Two examiners classified each child's level of gross motor function independently. We calculated kappas for individual levels and across all levels to study interrater reliability. RESULTS: The individual kappa for level V changed from 0.59 in the first reliability study to 0.87 in the second reliability study, whereas the overall kappa changed from 0.64 to 0.66. In the second reliability study, the factors that seemed to affect the reproducibility were the unfamiliar words used in the system, partial agreement of the children's status, and thinking of future levels. CONCLUSIONS: Explanation of words and a note stressing the importance of the introduction part should be added to the system for Japanese clinicians.
