“…studied the test-retest in MS with a time difference of a week, using the same platform as ours on a firm surface with eyes open and closed, showing lower repeatability values in the velocity moment in ICC, SEM and CV. By contrast, researchers such as Wajda et al22 ) showed reliability in MS over three month test-retest reliability of CoP motion during standing balance in individuals with MS obtaining results that were very similar to those we obtained from our ICC results from the variable of speed along both axes with eyes open and closed on a firm surface. This suggests to us that adding a dual task to the measurements as done by Wadja et al22 ) might increase the attention of the individual with MS and thus its reliability in time4 ) .…”

[Purpose] The purpose of this study was to analyse the intraday test-retest reliability of stabilometric measurements on the Centre of Pressure (CoP) in persons with Multiple Sclerosis. [Subjects and Methods] The measurements were taken with the subject standing on the force platform with both feet together, in four different conditions: eyes open and closed whilst standing on both a rigid surface and then on foam. The measurements were taken on three occasions with intervals of 20 minutes between them. 18 persons with confirmed Multiple Sclerosis (MS), (aged 44.4 ± 13.3 years and 3.5 ± 1.5 EDSS) participated in the study. Relative reliability was measured using the intraclass correlation coefficient (ICC) and the 95% confidence interval (95% CI); and the absolute reliability using the coefficient of variation (CV) and standard error of measurement (SEM). [Results] The measurements of the CoP in all of the variables in each of the four conditions, showed a reliability of good to excellent (ICC=0.69–0.92) in the intraday test-retest. The variables which showed greatest consistency with repetition were X Speed, Y Speed and Side Length. [Conclusion] Given the results it would seem that the best variables for monitoring postural control in persons with MS are Speed on X and Y along with Side Length.

“…A total of 105 variables relating to postural control were examined across the included studies, the majority using posturography. Advancements in posturography have been valuable in enabling reliable and objective assessments of postural control [63]; however, these advancements have added a significant difficulty with a seemingly infinite number of measurement variables at the disposal of the researcher with little agreement surrounding the key outcomes for extraction [64]. This review highlights the necessity of the development of a core measurement set for postural control.…”

“…Unfortunately, many of these scales are limited in their ability to accurately monitor progression of disease or intervention efficacy due to inherent subjectivity, lack of sensitivity in differentiating between groups, and poor reliability [5, 7]. Objective postural measures obtained from motion capture and posturography in PwMS have demonstrated fair to excellent validity and reliability in previous studies [8, 9]. Although effective, motion capture and force platform systems are not practical for use in most clinical settings due to high cost, difficulty of use, and lack of portability.…”

BackgroundThere is a need for objective movement assessment for clinical research trials aimed at improving gait and balance in persons with multiple sclerosis (PwMS). Wireless inertial sensors can accurately measure numerous walking and balance parameters but these measures require evaluation of reliability in PwMS. The current study determined the test-retest reliability of wireless inertial sensor measures obtained during an instrumented standing balance test and an instrumented Timed Up and Go test in PwMS.MethodsFifteen PwMS and 15 healthy control subjects (HC) performed an instrumented standing balance and instrumented Timed Up and Go (TUG) test on two separate days. Ten instrumented standing balance measures and 18 instrumented TUG measures were computed from the wireless sensor data. Intraclass correlation coefficients (ICC) were calculated to determine test-retest reliability of all instrumented standing balance and instrumented TUG measures. Correlations were evaluated between the instrumented standing balance and instrumented TUG measures and self-reported walking and balance performance, fall history, and clinical disability.ResultsFor both groups, ICCs for instrumented standing balance measures were best for spatio-temporal measures, while frequency measures were less reliable. All instrumented TUG measures exhibited good to excellent (ICCs > 0.60) test-retest reliability in PwMS and in HC. There were no correlations between self-report walking and balance scores and instrumented TUG or instrumented standing balance metrics, but there were correlations between instrumented TUG and instrumented standing balance metrics and fall history and clinical disability status.ConclusionsMeasures from the instrumented standing balance and instrumented TUG tests exhibit good to excellent reliability, demonstrating their potential as objective assessments for clinical trials. A subset of the most reliable measures is recommended for measuring walking and balance in clinical settings.
