S320 Vol. 45 No. 5 Supplement<br />

METhOds: A total of 43 females participated (control vs. pain groups: 23 vs. 20<br />

individuals, age 36.83±8.04 vs. 46.65±12.66 yrs, BMI 22.77±2.99 vs. 24.07±3.32,<br />

& WHR .76±.05 vs. .80±.069). As subjective measures of the pain rating, Visual<br />

Analogue Scale(VAS score 0~10; Huskisson, 1979) and Oswestry back pain disability<br />

index (ODI score 0~45; Fairbank et al., 1980) were employed. As an objective<br />

measure, a mean of Time Up and Go test(TUG; Podsiadlo et al., 1991) was employed,<br />

which is a 3m round-trip walk from the sit position (second) performing three times. A<br />

pedometer(HJ720IT, Omron; Zhu & Lee, 2010) was worn for 7 consecutive days. After<br />

running descriptive analysis, ANCOVA was applied to examine the group difference<br />

adjusted for age. To scrutinize the construct and convergent validity of the pain scales,<br />

the spearman correlations were calculated. ROC curves were calculated to determine<br />

the cut-off of pain scores for setting the walking steps with SPSS 20 and α=.05.<br />

rEsuLTs: The means of major variables by groups(control vs. pain) were as follows:<br />

Total steps: 8164±3473 vs. 7632±3586; VAS 1.00±1.04 vs. 3.25±1.89; ODI 2.96±2.27<br />

vs. 10.05±6.07; TUG7.43±0.49 vs. 8.22±0.78, respectively. After adjusted for age,<br />

VAS, ODI, and TUG showed the statistical difference by groups with p
