BACKGROUND: Autistic Spectrum Disorder (ASD) presents with a multitude of problems such as physical, social, emotional, psychological, etc. Most common physical problems are impairments in standing balance and posture. It is unknown whether these impairments have any association between tactile sensation or are purely due to deficits in sensory processing and integration. We hypothesized that foot tactile sensation in ASD is positively correlated to performance in standing balance as measured by Pediatric Balance scale. METHODS: The data collected at Heartshare Human Services of New York was used for secondary analysis. It consisted of 12 participants and included: 1. Muscle and joint ROM testing to rule out any muscle involvement in balance problems. 2. Tactile sensation testing at four sites on sole of foot bilaterally using Semmes Weinstein monofilament. 3. Pediatric Balance Scale (PBS) for balance testing. RESULTS: We found significant positive correlation between cutaneous tactile sensation (SWF) and Pediatric Balance scale (PBS) measures in our participants i.e., reduced tactile sensation was moderately associated with impaired balance score. CONCLUSIONS: We propose that during conventional clinical assessment for individuals with ASD, foot tactile sensation should not be overlooked, and included as a part of somato-sensory assessment. In addition, enhancing foot tactile sensation could also be used for targeted interventions to improve balance in children with ASD. KEY WORDS: ASD, tactile, balance, posture.

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

The details of the IRB/oversight body that provided approval or exemption for the research described are given below:

This study was deemed exempt from Institutional Review Board (IRB) review by the IRB at the University of Vermont/University of Vermont Health Network (Exempt Criteria 45 CFR 46.104(d)(4)(ii)). The information was utilized by the authors in such a manner that the identity of the participants could not readily be ascertained directly or through identifiers linked to the participants, the authors did not contact the participants, and the authors will not re-identify participants.

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).
