Deliberately Light Interpersonal Contact Affects the Control of Head Stability During Walking in Children and Adolescents With Cerebral Palsy

Published:February 28, 2017DOI:


      • Apex interpersonal touch (IPT) alters locomotor control of head sway in cerebral palsy (CP).
      • Trunk IPT acts in opposition to head IPT in CP.
      • IPT affects typically developed individuals differently than individuals with CP.



      To evaluate the potential of deliberately light interpersonal touch (IPT) for reducing excessive head and trunk sway during self-paced walking in children and adolescents with cerebral palsy (CP).


      Quasi-experimental, proof-of-concept study with between-groups comparison.


      Ambulant care facility, community center.


      Children and adolescents (N=65), consisting of those with CP (spastic and ataxic, n=26; Gross Motor Function Classification System I–III; mean age, 9.8y; 11 girls, 15 boys) and those who were typically developed (TD, n=39; mean age, 10.0y; 23 girls, 16 boys).


      IPT applied by a therapist to locations at the back and the head.

      Main Outcome Measures

      As primary outcomes, head and trunk sway during self-paced walking were assessed by inertial measurement units. Secondary outcomes were average step length and gait speed.


      CP group: apex and occiput IPT reduced head velocity sway compared with thoracic IPT (both P=.04) irrespective of individuals' specific clinical symptoms. TD group: all testing conditions reduced head velocity sway compared with walking alone (all P≤.03), as well as in apex and occiput IPT compared with paired walking (both P≤.02).


      Deliberately light IPT at the apex of the head alters control of head sway in children and adolescents with CP. The effect of IPT varies as a function of contact location and acts differently in TD individuals.


      List of abbreviations:

      CP ( cerebral palsy), GMFCS ( Gross Motor Function Classification System), HVS ( head velocity sway), IPT ( interpersonal touch), TD ( typically developed), TVS ( trunk velocity sway)
