“…saliva or blood contamination, during dental impression making or margin geometry, lead to unintended modifications in coping fit 18 . In addition, in vivo studies evaluating the intra- and interrater reliability of measurement techniques usually include different patients 1 , 3 , 8 . To simulate in vivo conditions, we performed modifications on purpose to create different CAD models.…”

“…The first investigator repeated the examination of all existing 80 silicone replicas for the LMMs with the frequently used interval of one week in intra-rater reliability studies 1 , 3 , 8 , resulting in two measurements: I1.1 and I1.2. The measurements of the 80 replicas' thickness were analyzed separately for the first and second examination and for the measurement points.…”

The aim of this in vitro study was to assess the reliability of two measurement systems for evaluating the marginal and internal fit of dental copings.Material and MethodsSixteen CAD/CAM titanium copings were produced for a prepared maxillary canine. To modify the CAD surface model using different parameters (data density; enlargement in different directions), varying fit was created. Five light-body silicone replicas representing the gap between the canine and the coping were made for each coping and for each measurement method: (1) light microscopy measurements (LMMs); and (2) computer-assisted measurements (CASMs) using an optical digitizing system. Two investigators independently measured the marginal and internal fit using both methods. The inter-rater reliability [intraclass correlation coefficient (ICC)] and agreement [Bland-Altman (bias) analyses]: mean of the differences (bias) between two measurements [the closer to zero the mean (bias) is, the higher the agreement between the two measurements] were calculated for several measurement points (marginal-distal, marginal-buccal, axial-buccal, incisal). For the LMM technique, one investigator repeated the measurements to determine repeatability (intra-rater reliability and agreement).ResultsFor inter-rater reliability, the ICC was 0.848-0.998 for LMMs and 0.945-0.999 for CASMs, depending on the measurement point. Bland-Altman bias was −15.7 to 3.5 μm for LMMs and −3.0 to 1.9 μm for CASMs. For LMMs, the marginal-distal and marginal-buccal measurement points showed the lowest ICC (0.848/0.978) and the highest bias (-15.7 μm/-7.6 μm). With the intra-rater reliability and agreement (repeatability) for LMMs, the ICC was 0.970-0.998 and bias was −1.3 to 2.3 μm.ConclusionLMMs showed lower interrater reliability and agreement at the marginal measurement points than CASMs, which indicates a more subjective influence with LMMs at these measurement points. The values, however, were still clinically acceptable. LMMs showed very high intra-rater reliability and agreement for all measurement points, indicating high repeatability.

“…The RT test is essentially a speed test of the cognitive-motor interaction, which is a major component of the motor skills required for successful balance recovery [ 40 ]. Additionally, the WBB allows for reliable testing of balance [ 41 ] and strength [ 28 , 29 ], both of which are important risk factors for falling [ 3 , 5 ]. The reliable assessment of these risk factors has generally been restricted to specialized fall clinics due to the significant costs of the stationary laboratory equipment needed.…”

“…Secondly, it has demonstrated good within-day and between-day reproducibility (intraclass correlation coefficient 0.76–0.87), and it is able to differentiate between young and older adults in both upper and lower limb RT tests [ 24 ]. Thirdly, WBB has shown similar or better reproducibility results for other clinically relevant parameters, such as isometric handgrip strength [ 25 ], balance assessment [ 26 , 27 ], and uni- [ 28 ] and bilateral [ 29 ] lower limb strength. Finally, it has successfully been used as intervention tool for enhancing balance control in older adults [ 30 ].…”

BackgroundFalls among older adults is one of the major public health challenges facing the rapidly changing demography. The valid assessment of reaction time (RT) and other well-documented risk factors for falls are mainly restricted to specialized clinics due to the equipment needed. The Nintendo Wii Balance Board has the potential to be a multi-modal test and intervention instrument for these risk factors, however, reference data are lacking.ObjectiveTo provide RT reference data and to characterize the age-related changes in RT measured by the Nintendo Wii Balance Board.MethodHealthy participants were recruited at various locations and their RT in hands and feet were tested by six assessors using the Nintendo Wii Balance Board. Reference data were analysed and presented in age-groups, while the age-related change in RT was tested and characterized with linear regression models.Results354 participants between 20 and 99 years of age were tested. For both hands and feet, mean RT and its variation increased with age. There was a statistically significant non-linear increase in RT with age. The averaged difference between male and female was significant, with males being faster than females for both hands and feet. The averaged difference between dominant and non-dominant side was non-significant.ConclusionThis study reported reference data with percentiles for a new promising method for reliably testing RT. The RT data were consistent with previously known effects of age and gender on RT.

Unilateral lower limb strength assessed using the Nintendo Wii Balance Board: a simple and reliable method

Abstract: A high relative and an acceptable absolute reproducibility was seen when using the Nintendo Wii Balance Board for testing unilateral lower limb strength in community-dwelling older adults. The WBB correlated strongly with the SID.
