Hi Everyone,
I thought I'd add my bit. I'm an occupational therapist working with children with autism, some of whom toe walk. For starters, SPD is not yet a recognised diagnosis so while we may describe a child as having SPD, we do not diagnose them with it. A child's sensory processing and sensory integration is assessed by using the Sensory Integration Praxis Test (SIPT) or more commonly the Clinical Observations (a non standardised ax originally developed by A Jean Ayres). This information is collated with the results of the sensory profile mentioned previously and general observations of the child's function in different settings (school, clinic, home etc.).
I have been working on the hypothesis that toe walking is a sensory seeking behaviour, with the child seeking deep pressure, proprioceptive or vestibular stimulation (or all three). All of the children I see have significant sensory processing dysfunction and this hypothesis is in line with their overall sensory profile. In terms of treatment, I use a sensory diet along with the Wilbarger Brushing Protocol and I have also been using Kinesio Tex Tape to inhibit gastroc/soleus and facilitate tib. anterior. The sensory diet and Wilbarger Protocol improve a child's sensory integration and decrease sensory seeking behaviours. The Kinesio tape increases proprioception to the muscles as well as utilising the specific muscle application. Within treatment sessions we frequently use vestibular, proprioceptive and deep pressure stimulation.
I realise that there is no significant scientific research to support this, as I said this is just a hypothesis. I have however, seen a decrease in toe walking and improvement in gait stability in the children I have been treating.
