Purpose: The purpose of this systematic review of the literature was to determine the efficacy of orthoses for children with hypotonia and provide a concise summary of the state of the evidence in this area.
Methods: Fifteen search terms were used to find articles addressing children with hypotonia, orthotic use, and physical therapy.
Results: Ten articles met the inclusion criteria, but no level I evidence was found. Data were reported for body structure and activity components, but not participation outcomes. Current evidence suggests that foot orthoses and supramalleolar orthoses may benefit children with hypotonia; however, the evidence is low level.
Conclusion: The evidence for efficacy of orthoses for children with hypotonia continues to have gaps with the following questions still unanswered: When is the optimal time to introduce orthoses? Are foot orthoses or supramalleolar orthoses more efficacious? Should orthoses be combined with physical therapy?
