Lord Kelvin 1824 -1907

“When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, your knowledge is of a meager unsatisfactory kind: It may be the start of knowledge, but you have scarcely in your thoughts, advanced to the stage of science.”

“One of the most dramatic

developments in pain research

and therapy has been the recent

proliferation of techniques for the

measurement and assessment of

Pain” R. Melzack

Pain Assessment

Every patient complaining of chronic pain deserves to be examined.

Palpation and the utilisation of pain assessment

tools including: Pain Diagrams, the McGill Pain

Questionnaire, Visual Analogue Pain Scale are

all a necessary part of this process.( And should

always be carried out before referral for

psychologically based therapies.)

  • Visual Analogue Scale ( VAS )
  • McGill Pain Questionnaire
  • Pain Diagram


  • Pressure Threshold Algometry
  • Differential Local Anesthetic Blocks
  • Thermography, EMG etc.
visual analogue scale
Visual Analogue Scale
  • The VAS is a simple robust pain measurement tool
  • It can be used to measure severity & or Improvement
  • It can be reliably used for children over the age of five
  • The VAS is usually designed as a 10cm line with descriptors at each end.

The VAS for Pain severity measurement

No Pain Worst Possible Pain

The VAS for Treatment Effect

No Pain Complete Pain

Visual Analogue Scale

No Pain Worst Possible Pain

The example shows a patient recording a 9.0

i.e. The patient has made a mark 9cms from the no pain end

of the scale.

NB The VAS can be compromised if descriptors or numbers are added between the end points.

{The 10 cm line allows for easy measurement and recording}
