Some children with idiopathic toe walking display sensory processing difficulties but not all: A systematic review

Aim Idiopathic toe walking (ITW) is a diagnosis for children who toe walk without another diagnosis known to cause toe walking. Recent research has suggested that children with ITW may have mild motor planning challenges and sensory processing differences. The primary aim of this systematic review was to determine whether children diagnosed with ITW have differences in their sensory processing compared to typically developing children. Secondary aims included determining how sensory processing was assessed in this population and documenting the broad clinometric and psychometric properties of any assessment tools. Methods MEDLINE, CINAHL, AMED and Embase were searched for relevant literature in English. Studies were eligible for inclusion if they described children aged 3 and 18 with idiopathic toe walking and reported a sensory processing domain. Results Twelve articles met the inclusion criteria; however, only two papers included data permitting meta‐analysis. Meta‐analyses of vibration perception threshold using a random effect model were not significant (p = 0.31). Other data were synthesised by narrative and showed a high heterogeneity across multiple sensory processing domains. Conclusion This study highlights that despite children with ITW often conceptualised as possessing sensory processing challenges, there is little evidence supporting this theory. Further research on sensory processing in children with this gait pattern is necessary.
