The visual analogue scale in the assessment of grip strength
Annals of the Rheumatic Diseases
|August 1, 1978
Abstract:
The accuracy of information derived from a visual analogue scale has been assessed by comparing the measured grip strength of 100 subjects against their estimate of grip strength scored on a visual analogue scale. There was relatively poor correlation between the measured and assessed values, suggesting that similar inaccuracies may occur when the scales are used to assess subjective phenomena.
