Opis:
For the evaluation of the functionality and mobility of the spine, several methods have been developed. The purpose of this study was to estimate the test-retest reliability of the Spinal Mouse, a new, non-invasive, computer-assisted wireless telemetry device for the assessment of the curvatures, the mobility and the functionality of the spine. Materials and methods: the test-retest reliability was evaluated in 50 adults with back or low back pain. Twenty four parameters were studied in the sagittal and frontal plane. For the characterization of the precision, the intraclass correlation coefficient and the standard error of measurement were used. Results: in the sagittal plane, 22 of the 24 parameters showed high and good reliability, while only two fair and poor. In the frontal plane, 17 parameters showed high and good reliability, five fair and two poor. Discussion: the Spinal Mouse showed excellent test-retest reliability in the sagittal plane, while a slightly inferior performance in the frontal plane, for the evaluation of curvatures, deformation and mobility of the spine.

Opis:
The aim of this study was to analyse absolute and relative reliability of a number of postural static stability measures obtained from a GYKO inertial sensor system in young adults. Methods: The study examined 29 healthy non-athlete young adults. A test was performed for 30 s while standing on one foot, without moving, with eyes open and arms relaxed along the sides of the body. The examinations were performed twice, with a one-week interval. Relative reliability was measured using the intraclass correlation coefficient (ICC) and the 95% confidence interval (95% CI), whereas the absolute reliability was evaluated based on the standard error of measurement (SEM) and the minimal detectable change (MDC). Results: The results of this study showed moderate to good relative reliability scores for all the postural stability measures, with ICC values ranging from 0.62 to 0.70. For most of the analysed variables, SEM% ranged from ca. 10 to 14%. Relatively high SEM% values were obtained only for two variables (Area, Convex Hull Area). Conclusions: The low costs of GYKO inertial sensor systems, the fast and easy installation, the mobility and high reliability of the measurement of postural stability show that it can be effective alternative to stabilographic platforms.
