“…We believe this is due to the similarity between the symptoms of the vestibular alteration study group and ours. In respect of the extension on both axes variable we found the Brenton-Rule et al study20 ) which shows results of excellent intraday reliability with an interval of an hour between each evaluation (ICC=0.89–0.92), carried out with eyes open and closed on a firm surface in elderly persons with ICC values that were very similar to the results from our study with the same conditions and variables studied.…”

[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.

“…However, while the clinical utility of the MatScan is beneficial, technological differences may limit the ability of the device to perform accurate COP measures compared to traditional force-plates. The pressure-mat has previously been shown to be reliable device for COP measures during bipedal static balance; 6 however, validity of the MatScan COP measurements and the ability of the device to detect changes in postural sway during a single leg stance has not been established. Therefore, the objectives of this study were to compare the measurement of 4 COP excursion variables during single-leg static balance between a MatScan pressure-mat and a force-plate device and to compare the ability of each device to detect changes in COP variables when visual input is removed.…”

Context: Measurements of center-of-pressure (COP) excursions during balance are common practice in clinical and research settings to evaluate adaptations in postural control due to pathological or environmental conditions. Traditionally measured using laboratory force plates, pressure-mat devices may be a suitable option for clinicians and scientist to measure COP excursions. Objective: Compare COP measures and changes during balance between MatScan® pressure mat and force plate. Design: Validation study. Setting: Laboratory. Participants: 30 healthy, young adults (19 female, 11 male, 22.7 ± 3.4 y, 70.3 ± SD kg, 1.71 ± 0.09 m). Main Outcomes: COP excursions were simultaneously measured using pressure-mat and forceplate devices. Participants completed 3 eyes-open and 3 eyes-closed single-leg balance trials (10 s). Mean of the 3 trials was used to calculate 4 COP variables: medial-lateral and anterior-posterior excursion, total distance, and area with eyes open and eyes closed. Percent change and effect sizes were calculated between eyes-open to eyes-closed conditions for each variable and for both devices. Results: All COP variables were highly correlated between devices for eyes-open and eyes-closed conditions (all r > .92, P < .001). BlandAltman plots suggest the pressure-mat COP measurements were smaller than those of the force-plate, and the differences between devices appeared to increase as the measurement magnitude increased. Percent change in COP variables was highly correlated between devices (r > .85, P < .001). Cohen d effect sizes between eyesopen and eyes-closed were all large (d > 2.25) and similar in magnitude between devices. Conclusion: COP measures were correlated between devices, but values tended to be smaller using the pressure mat. The pressure mat and force plate detected comparable magnitude changes in COP measurements between eyesopen and eyes-closed. Pressure mats may provide a viable option for detecting large magnitude changes in postural control during short-duration testing.

“…Although force platforms are a reliable and sensitive tool, 40 the cost, required space, and lack of portability result in limited clinical usage, as well as limit the ability to use it across different populations such as residential care communities. In addition, there are alternatives such as TekScan MatScan 41 , and Wii Balance Board 10 which have shown good reliability in estimating COP. Although these tools can provide information about the control of the movements, it is recognized that these measurements correlate highly with the movement of the center of mass that can be estimated from body-worn accelerometers, which overcome the limitations of cost and portability.…”

Standing balance and strength measurements in older adults living in residential care communities

et al. 2016

Research on balance and mobility in older adults has been conducted primarily in lab-based settings in individuals who live in the community. Although they are at greater risk of falls, residents of long-term care facilities, specifically residential care communities (RCCs), have been investigated much less frequently. We sought to determine the feasibility of using portable technology-based measures of balance and muscle strength (i.e. an accelerometer and a load cell) that can be used in any RCC facility. Twenty-nine subjects (age 87±6 years) living in RCCs participated. An accelerometer placed on the back of the subjects measured body sway during different standing conditions. Sway in antero-posterior and medio-lateral directions were calculated. Lower extremity strength was measured with a portable load cell and the within-visit reliability was determined. Assessments of grip strength, gait speed, frailty, and comorbidity were also examined. A significant increase in postural sway in both the AP and ML directions occurred as the balance conditions became more difficult due to alteration of sensory feedback (p < 0.001) or reducing the base of support (p < 0.001). There was an association between increased sway and increased frailty, more comorbidities and slower gait speed. All strength measurements were highly reliable (ICC = 0.93 to 0.99).An increase in lower extremity strength was associated with increased grip strength and gait speed. The portable instruments provide inexpensive ways for measuring balance and strength in the understudied RCC population, but additional studies are needed to examine their relationship with functional outcomes.
