Abstract
Vertical spinal creep can be measured from height loss of the body which can be used as an index of spinal loading. This height loss can be assessed with a stadiometer that is a safe and highly reliable device. The firstly invented stadiometer in Thailand is called “height loss measuring stadiometer.” This study investigated the reliability of the height loss measuring stadiometer in sitting posture by examining the reliability of the digimetic indicator device and the reliability of the measurement. Subjects were 10 healthy participants (5 males, 5 females). Intraclass Correlation Coefficiency (ICC) and means of standard deviations (SDs) were calculated. The results showed very high reliability of the digimetic indicator (ICC 1,1 = 1.00) and high reliability of the height loss measuring stadiometer (ICC 3,1 = 0.96). Mean of standard deviations was 0.17 millimeter which was less than the generally acceptable value that should be less than 0.5 millimeter. We conclude that the currently invented height loss measuring stadiometer is a highly reliable device that can be used for investigating the vertical spinal creep or measuring the height loss of the body from spinal loading after several activities.
