Leg length discrepancy is common among patients with scoliosis. Some studies reported reduced functional scoliosis curves with correction of leg length discrepancy. Others, however, have shown that induced leg length discrepancy has little effects on spinal deformities. Also, small number of studies assessed the use of foot orthoses in patients with faulty foot biomechanics and their impact on idiopathic scoliosis. In this context, a review of the literature is needed to determine the current evidence for the appropriate use of sole lift and foot orthoses in a context of scoliosis. [Methods] A literature review was performed. [Results] It appeared that sole lifts are indicated for functional lumbar scoliosis when the level of the sacrum is parallel to that of the hips. Sole lifts may not be indicated for patients with structural scoliosis, seemingly inducing a compensatory curve. Custom foot orthoses were found to reduce spinal curves in juvenile patients with mild idiopathic scoliosis and concomitant abnormal foot biomechanics. [Conclusion] Sole lift appeared to be indicated in the presence of certain types of functional scoliosis. Custom foot orthoses can be considered in the management of mild idiopathic scoliosis in juvenile patients. Evidence, however, is low and quality studies are needed to validate these findings.
Purpose: The 2021 SOSORT guidelines stipulated that braces be prescribed for adult scoliosis with chronic pain and progressive curve. Yet, there have been no objective protocols relating to the prescription of the brace. Therefore, this review investigates if there are any objective criteria or generally agreed on protocols for brace prescription in adult scoliosis patients. Methods: Relevant papers were searched in PUBMED. Only articles that are in English and cover the clinical aspect of adult scoliosis bracing are included. Results: A total of twelve papers were identified. They include different adult scoliosis braces, ranging from elastic belts to rigid braces. The treatment protocol varied tremendously. No objective criteria were found concerning the prescription of a brace, daily wearing time, duration of the intervention, and weaning protocol. The brace treatment was primarily employed to manage low back pain. Conclusion: Our search showed no objective criteria and clear indications for bracing and no consensus concerning the prescription of braces, daily wearing time, and duration of the intervention for patients with adult scoliosis. The authors proposed prescription of a brace be based on more objective radiological criteria and severity of low back pain. Brace prescription should depend on the flexibility of the curve and can range from accommodative to rigid braces of corrective design. “Corrective” brace has to be worn at least 14 hours daily for six months or until the low back pain subsides to the extent that permits daily activities with minimal discomfort. “Accommodative” brace can be worn when required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
