“…Intertester and intra-tester ICC stability scores ranged from .70 to .42 and .80 to .43, respectively [26]. Schmitz & Arnold [26] concluded that the BBS was a reliable tool for testing dynamic stability. The BBS DLOS system appeared to accurately and uniquely depict dynamic balance in both pathological and healthy populations.…”

“…Hinman [27] suggested that dynamic balance testing using the BBS LOS test may have been too difficult for a participant population with pre-existing balance impairments as a percentage of test participants were unable to complete the DLOS tests without using upper extremity assistance to prevent complete loss of balance. Schmitz & Arnold [26] determined the intertester and intratester reliability values for the BBS DLOS for dynamic balance through a unilateral stance protocol based on anterior to posterior (A-P), medial lateral (M-L), and overall stability indices. Intertester and intra-tester ICC stability scores ranged from .70 to .42 and .80 to .43, respectively [26].…”

“…The Biodex Balance System dynamic limits of stability test (BBS DLOS) was used to discriminate dynamic balance between individuals with rheumatoid arthritis and controls [23], very old male and female nursing home residents [24], and for the quantitative assessment of balance in individuals with spinocerebellar ataxia [25]. Clinical utility of the BBS DLOS was determined through intra-tester, inter-tester [26] and test-retest reliability [27]. The BBS DLOS was compared to the NeuroCom Smart Balance Master system (NeuroCom International, Clackamas, OR) to assess the dynamic balance discrimination capacity between the two systems [1].…”

Background: The purpose of this study was to determine the possible concurrent validity of the tandem walk test as a measure of dynamic walking balance. Methods: Forty-nine healthy participants, age range 20-75 years (mean age 40.1 ± 17.1 years), performed the ten step tandem walk test and two clinical tests of dynamic balance using the Biodex Balance System (Biodex Medical Systems, Shirley, NY) dynamic limits of stability protocol and measures of gait variability assessed through gait center of pressure, spatial, and temporal parameters derived from an instrumented treadmill (h/p/cosmos sports & medical gmbh, Nussdorf-Traunstein, Germany; Zebris FDM-T, Isny im Allgau, Germany). Results: A moderate-high correlation was demonstrated between the ten step tandem walk test eyes open and measures of gait variability, step width (r=0.64 p<0.05) and step time variability ( r=0.67 p<0.05), age (r=0.69 p<0.05), and Biodex Balance System dynamic limits of stability (r=0.81 p<0.05). A moderate relationship was found between the ten step tandem walk test eyes open and measures of gait center of pressure variability (r=0.52 p<0.05). Correlation coefficient values between the ten step tandem walk test eyes open and Biodex Balance System dynamic limits of stability, gait temporal, center of pressure, and spatial parameters demonstrated increased strength when adjusted for age. Conclusion: The ten step tandem walk test demonstrated a moderate to high relationship with clinical tests of dynamic balance: Biodex Balance System dynamic limits of stability and gait center of pressure, spatial, and time parameters in a healthy population demonstrating concurrent validity as an objective measure of dynamic walking balance in a healthy population between the ages of 20 and 75 years.

“…(23) Body balance was estimated with a postural sway platform (Biodex Stability System; Biodex Medical Systems, Shirley, NY, USA). (24) Body balance was expressed as a stability index, a unitless measure that reflect the variance of platform displacement from level. A high number indicates less motion control and poor postural stability.…”

The purpose of this cross-sectional study was to examine the impact of long-term physical activity (PA) and calcium intake on non-weight-bearing radius and weight-bearing tibia. ). The distal end and shaft regions of the radius and tibia were evaluated with peripheral quantitative tomography (pQCT). For the shaft regions, bone mineral content (BMC), cortical cross-sectional area (CoA), cortical density (CoD), and bone strength index, that is, 1-11.9% of the density-weighted section modulus (BSI) were determined. For the distal ends, BMC, total cross-sectional area (ToA), trabecular density (TrD), and BSI were determined. The BMC at the distal radius in the young PA ؉ group was 6.6% (95% CI, 1-to 11.9%) lower than that of the PA ؊ group. A similar nonsignificant trend was found for the radial shaft. The radial shaft showed a mechanically more competent structure among the older subjects with a BSI 8.5% (95% CI, 1.8 -15.6%) higher in the older PA ؉ group than in the older PA ؊ group. The associations between calcium intake and the radial bone characteristics were systematically positive in both age groups. PA seemed to benefit the distal tibia. In the younger age group the TrD was 6.9% (95% CI, 1.8 -12.4%) higher in the PA ؉ group, and in the elderly the BMC was 5% (95% CI, 0.3-9.9%) higher in the PA ؉ group than in the PA ؊ group. Note that in the younger age group the ToA was 5.1% (95% CI, 0 -9.1%) smaller in the PA ؉ group than in the PA ؊ group, and in the older age group the ToA was 4.2% (95% CI, ؊0.3-8.9%) greater in the PA ؉ group than in the PA ؊ group. The association of PA and bone characteristics at the tibial shaft was positive in both age groups (statistically significant for the older subjects). The tibial shaft BSI of the older PA ؉ group was 8.6% (95% CI, 2.6 -14.9%) better than that of the old PA ؊ group. There was no association between calcium intake and the tibial bone characteristics in either age group. In conclusion, high calcium intake was positively associated with a mechanically competent structure in the radius among both younger and older women, whereas the influence of PA did not become apparent until older ages. PA seemed to benefit particularly the weight-bearing tibia, whereas calcium intake was not associated with the tibia. (J Bone Miner Res 2002;17:544 -552)
