Use of sensory dynamic orthosis in paediatric neuromuscular scoliosis: A pilot single-group pre-post study

IntroductionNeuromuscular scoliosis (NMS) in children poses significant challenges, including postural instability, pain, mobility limitations, and respiratory issues. Sensory dynamic orthosis (SDO) garments provide dynamic compression and proprioceptive feedback aimed at improving alignment and function. This pilot study explored the feasibility and preliminary effectiveness of SDO garments in the management of NMS.MethodsA single-group pre-post, multicentre pilot study was conducted in 30 paediatric patients who used the SDO® Advanced orthosis for six months. Radiographic outcomes (Cobb angle, coronal balance, pelvic obliquity) and functional assessments (FLACC-R scale, Barthel Index) were recorded at baseline and after the intervention. Caregiver-reported satisfaction and perceived functional changes were gathered through a custom-designed questionnaire.ResultsOf the 30 participants, 25 completed the study (median age 13 [IQR 10-15]). Statistically significant within-subject reductions in Cobb angle were observed during SDO use at baseline (median difference -2.6°, p<0.001) and at final evaluation (median paired difference -4.0°, p<0.001). Similar within-subject improvements in coronal balance were observed at both time points (baseline median paired difference -2.1 cm, p<0.001; final -1.8 cm, p=0.005). Pelvic obliquity and Barthel Index scores showed no significant changes. Most caregivers reported slight to moderate improvements in functional domains and high satisfaction. No serious adverse events were observed, and adherence was high.ConclusionsThis pilot study suggests that SDO garments may contribute to short-term postural spinal alignment and balance during wear and perceived functional benefits in children with NMS. These preliminary findings support further research through controlled trials with longer follow-up to clarify clinical relevance and durability of effects.
