How can Animal Pain be Assessed?
    The principles used in these guidelines for assessment of animal pain can be 
    found by clicking here.
    Either objective and / or subjective assessments are used in a comprehensive (systematic) 
    or easy to use (practical) way.  However, the sensitivity, reliability 
    and validity of all assessment methods should also be considered.
     
      - Objective Assessment,
      using physiological, biochemical and behavioural responses.
 
      - Subjective Assessment,
      using verbal descriptors, VAS
      and NRS scales.
 
      - Systematic Assessment accepts that 
      all aspects of the animal's mental, physical and behavioural state should, 
      ideally, be considered.  However, it is acknowledged that the time necessary to obtain 
      the information and the expertise required for its appropriate 
      interpretation may not always be readily available. 
 
      - Practical Assessment 
      accepts that quick and easily applied methods are required for routine application 
      under "field" conditions. Such methods involve reducing the 
      information obtained during systematic assessment. 
 
      - Validation 
      is achieved experimentally by demonstrating consistency between the 
      new method of assessment and established standard or independent methods.
