Therapeutic positioning improves typing speed on augmentative communication devices, though accuracy may decrease. This positioning intervention enhances functional use for individuals with head control challenges.

Area of Science:

  • Assistive Technology
  • Rehabilitation Engineering
  • Augmentative and Alternative Communication (AAC)

Background:

  • Review of therapeutic positioning literature concerning muscle tone and functional activities.
  • Exploration of the impact of positioning on individuals utilizing augmentative communication equipment.
  • Understanding the relationship between physical support and device interaction.

Observation:

  • Measurement of typing rate and accuracy using head-controlled augmentative communication devices.
  • Assessment of typing performance before and after implementing therapeutic positioning interventions.
  • Quantification of changes in head control during functional communication tasks.

Findings:

  • Significant increase in typing rate observed with therapeutic positioning.
