ABSTRACT

Objective : We investigated which measurement is more useful and reliable between NRS, horizontal VAS, and vertical VAS in 110 hospitalized patients who complain LBP and low extremity pain. Also, we analyzed interrelation in each measurement. Methods : Before we began investigation, we informed the objective and method of this investigation to patients. Then we checked patient's pain degree by using those three measurements(NRS, horizontal VAS, and vertical VAS). We evaluated that sensitivity, correlation and inter-individual variability of each measurement depended on analyzing values. Results : We included 108 patients because we excluded 8 patients who could not check VAS degree. Both of horizontal VAS and vertical VAS showed statically significant and high sensitivity appearing normal distribution shape. But NRS didn't show normal distribution shape. The mean value of horizontal VAS and NRS was significantly higher than NRS. There was no sharp difference clinically between horizontal VAS and NRS in inter-individual variability. The interrelation of each measurement were very close. Conclusions : There was significant difference between horizontal VAS, vertical VAS and NRS in statistics , not in clinical aspect. However, We can use those measurements usefully in pain evaluation because their interrelation is very close.
