Eligibility criteria using the PICOS (Population, Intervention, Comparison, Outcome and Study) design format to determine the studies to be included in this proposed scoping review protocol

Eligibility criteria	Description/characteristics
Population	Participants of all ages with idiopathic scoliosis are considered for inclusion in this scoping review. However, studies focusing on participants with other type of scoliosis are excluded.
Interventions	Orthotic treatments are included in this scoping review.
Comparators	No specific comparators are required for inclusion in the scoping review.
Outcomes	No specific outcomes are required for inclusion in the scoping review, as the purpose of the review is to determine the scope of the available evidence on orthotic treatments for individuals with idiopathic scoliosis.
Study design	Systematic reviews of experimental studies (eg, RCTs, pseudo-RCTs and pre–post studies) and meta-analyses are eligible for inclusion in the review. Systematic reviews that included experimental studies with observational or qualitative data collection and analysis are also eligible for inclusion in this scoping review.

RCTs, randomised control trials.
