Pressure mapping is a reliable method for assessing interface pressures, outperforming numerical data. This technique proved consistent across various seating surfaces and operator experience levels, enhancing pressure care assessments.

Area of Science:

  • Biomedical Engineering
  • Rehabilitation Science
  • Clinical Assessment Technology

Background:

  • Pressure mapping systems offer advanced technology for pressure care assessment.
  • Data can be presented numerically, as 3D grids, or color-coded maps.

Purpose of the Study:

  • Evaluate the reliability of pressure maps versus numerical data for interface pressure interpretation.
  • Determine inter- and intra-rater reliability of pressure map assessment.
  • Assess if reliability varies with operator experience and seating surfaces.

Main Methods:

  • A reliability study using the Force Sensing Array pressure mapping system.
  • Occupational therapists (experienced and students) ranked pre-recorded pressure maps.
  • Maps were recorded on diverse seating surfaces over time.

Main Results:

  • Pressure mapping proved a reliable method for interpreting interface pressures.
  • Significant agreement was found within and between operator groups (p < 0.001).
  • Reliability extended across all tested seating surfaces.

Conclusions:

  • Using pressure maps for interface pressure assessment in seating is supported over numerical data.
  • The method is reliable for both experienced and novice operators.
  • Reliability is consistent across a range of seating surfaces.
