Results summary:

  • Excellent same-day test-retest reliability (ICC = 0.94)
  • Method error (ME = .74), Coefficient of variation (MEcv = 7.25%), which confirms a change of one pound is real change
  • A change of one pound is significant and clinically meaningful for body weight values up to 140 pounds. A change of two pounds would be meaningful for body weight values > 140 pounds.

Spring Scale Test® (SST®) 10% TBW performance value:

  • Sensitivity (93%), Specificity (96.6%)
  • ROC Area Under the Curve (AUC = 0.992)
  • Highest level of discrimination to fall status compared to the TUGT, gait speed, single limb stand test and tandem stand test
  • Logistic regression supports the efficiency of the RIPPS® 10% TBW performance measure for identifying fall history in the sample studied
  • Faller mean % TBW 7.5 (1.4)
  • Non-faller mean % TBW 12.3 (1.7)
