Measuring the client’s body

Body measurement is also referred to as anthropometric measurement. The measuring process should take a maximum of 10 minutes.

CallipersHelpful Equipment:

  • Recording Form
  • Firm assessment surfaces such as a plinth and firm chair
  • Goniometer
  • Metal measuring tape - units measured in millimetres or inches as appropriate
  • Foot block/platform to support the feet if the sitting surface is too high
  • Clip boards or wooden rulers as reference point for measuring
  • Callipers enable measurements to be obtained quickly and accurately.

Preparation

  • Be prepared by having the tools and the recording form within reach
  • Consider having another person if possible to scribe the measurements or to assist with holding the clip board in position as a reference point
  • The measuring calliper is a very useful tool when you are on your own.
  • Body measurement can be conducted straight after the supine or sitting MAT assessments to reduce the number of client transfers, depending on the client needs (see below Risk Assessment and Safety Concerns)
  • A general guide for conducting a body measurement
    • For hands-free sitters and hands-dependant sitters who are able to maintain the required posture, sitting is the best position for the process
    • For dependant sitters, measure in supine
    • Refer to Timeline  suggestion for assessment task
  • Seating postural goals are established after the MAT process outlined in Module 3. The client should be measured according to this established desired posture.

Risk assessment and safety concerns

The body measurement process may be modified to ensure client and staff safety. Consider the following risk factors:

  • Sitting balance
  • Muscle spasms
  • Large or heavy clients
  • Unstable or soft assessment surface, and
  • Pressure injuries or wounds: an existing wound should not be placed in contact with firm support surface during assessment, in seating or lying.

Risk reduction strategies for measuring the client’s body

  1. Consider involving a second assessor or helper if there are any manual handling risks or safety concerns during the body measurement process.
  2. Measure in supine or use a firm sitting chair for those who:
    • are dependant sitters
    • are unable to maintain the required sitting posture without assistance from another person
    • have safety concerns with sitting due to spasm (e.g. hips and knees in extension spasm pattern)
  1. Measure in supine for clients with pressure injuries under the pelvis
  2. In the community setting, a padded firm sitting chair (e.g. dining chair) or a full length transfer board over a soft bed can be utilised as an assessment surface.

Note

Remove the board once the assessment is complete to prevent skin breakdown. Do not use the transfer board as the assessment surface if the client has a wound that is in direct contact with it.
