Insights
Single Event Multilevel Surgery (SEMLS) significantly improves gait and function in children with bilateral spastic cerebral palsy (BSCP). These gains are maintained at 5-year follow-up, demonstrating long-term effectiveness.
Area of Science:
- Orthopedic Surgery
- Pediatric Neurology
- Rehabilitation Medicine
Background:
- Single Event Multilevel Surgery (SEMLS) is a standard treatment for improving gait and function in children with bilateral spastic cerebral palsy (BSCP).
- Previous randomized controlled trials (RCTs) showed improvements at 12 and 24 months post-surgery.
- This study aimed to assess the long-term maintenance of these improvements at 5 years.
Purpose of the Study:
- To determine if the gait and functional improvements achieved after SEMLS in children with BSCP are sustained at a 5-year follow-up.
- To evaluate the long-term efficacy of SEMLS in managing gait and motor function deficits in pediatric cerebral palsy.
Main Methods:
- A prospective cohort study followed 19 children with BSCP (GMFCS levels II-III) for 5 years post-SEMLS.
- Outcome measures included Gait Profile Score (GPS), Gillette Gait Index (GGI), Gait Deviation Index (GDI), Gross Motor Function Measure (GMFM66), and Functional Mobility Scale (FMS).
Main Results:
- Eighteen children completed the 5-year follow-up; one was excluded due to neurological deterioration (revised diagnosis to HSP).
- Significant improvements were observed at 5 years: GPS improved by 5.29° and GMFM66 by 3.3%.
- No significant differences were found between 1-year and 5-year, or 2-year and 5-year outcomes (except GMFM66), indicating stable improvements.
Conclusions:
- SEMLS leads to clinically and statistically significant improvements in gait and function for children with BSCP.
- These improvements are maintained at the 5-year follow-up point, confirming the long-term benefits of the surgical intervention.
Background:
Single Event Multilevel Surgery (SEMLS) is considered the standard of care to improve gait and function in children with bilateral spastic cerebral palsy (BSCP). We have demonstrated in a randomized controlled trial (RCT) of SEMLS, that gait was improved at 12 months after surgery and gross motor function at 24 months after surgery. The question addressed in this study, was to determine if improvements in gait and function, would be maintained at 5 year follow-up.
Methods:
Nineteen children with BSCP, GMFCS levels II (14 children) and III (5 children), mean age 9.7 years (range 7.7-12.2 years) participated in a prospective cohort study following participation in a RCT, with follow-up to 5 years. Outcome measures were Gait Profile Score (GPS), Gillette Gait Index (GGI), Gait Deviation Index (GDI), Gross Motor Function Measure (GMFM66) and Functional Mobility Scale (FMS).
Results:
Eighteen children have completed follow-up, with interval analysis at 1, 2 and 5 years post SEMLS. One child was excluded because of neurological deterioration and his diagnosis was revised to Hereditary Spastic Paraparesis (HSP). GPS improved by 5.29° and GMFM66 by 3.3% at 5 years post SEMLS. Differences between outcome measures at 1 versus 5 years and 2 versus 5 years (except GMFM66) were not significant, indicating that improvements in gait and gross motor function were stable over time.
Conclusions:
SEMLS results in clinically and statistically significant improvements in gait and function, in children with BSCP, which were maintained at 5 years after surgery.
