Insights
Selective dorsal rhizotomy (SDR) plus physiotherapy (PT) effectively reduces spasticity and improves gross motor function in children with spastic diplegia compared to PT alone.
Area of Science:
- Pediatric neurology
- Neurosurgery
- Rehabilitation medicine
Background:
- This meta-analysis compares selective dorsal rhizotomy (SDR) plus physiotherapy (PT) against PT-only for treating spastic diplegia in children.
- Utilizes data from three randomized clinical trials with 90 participants, focusing on spasticity (Ashworth scale) and function (Gross Motor Function Measure [GMFM]).
Discussion:
- SDR+PT demonstrated a statistically significant reduction in spasticity (mean difference -1.2, p<0.001) and a significant improvement in gross motor function (difference +4.0, p=0.008).
- A direct correlation was observed between the extent of dorsal root tissue transected and functional gains in the SDR+PT group.
Key Insights:
- SDR+PT is an efficacious intervention for reducing spasticity in pediatric spastic diplegia.
- The procedure shows a small but positive effect on gross motor function, particularly in children with moderate disability (GMFCS levels II-III).
Outlook:
- Further research could explore long-term functional outcomes and optimal surgical parameters for SDR.
- Investigating patient selection criteria to maximize functional benefits from SDR+PT is warranted.
Abstract:
This study is a comparative analysis and meta-analysis of three randomized clinical trials. Children with spastic diplegia received either 'selective' dorsal rhizotomy (SDR) plus physiotherapy (SDR+PT) or PT without SDR (PT-only). Common outcome measures were used for spasticity (Ashworth scale) and function (Gross Motor Function Measure [GMFM]). Baseline and 9- to 12-month outcome data were pooled (n=90). At baseline, 82 children were under 8 years old and 65 had Gross Motor Function Classification System level II or III disability. Pooled Ashworth data analysis confirmed a reduction of spasticity with SDR+PT (mean change score difference -1.2; Wilcoxon p<0.001). Pooled GMFM data revealed greater functional improvement with SDR+PT (difference in change score +4.0, p=0.008). Multivariate analysis in the SDR+PT group revealed a direct relationship between percentage of dorsal root tissue transected and functional improvement. SDR+PT is efficacious in reducing spasticity in children with spastic diplegia and has a small positive effect on gross motor function.
