“…Participants stood on an unstable platform, shifted, and controlled their COG within their moving BOS in an attempt to direct a cursor on a biofeedback display from a centralized target to eight perimeter targets as quickly and with as little path deviation as possible. DLOS data were gathered over the course of three sets, each set consisted of three untimed trials with a three minute rest interval between each set (52). Balance platform stability was set at level eight of a 12 point scale with 12 being doi: 10.7243/2055-2386-4-12 most stable and one being least stable.…”

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.

“…A relationship exist between severity of motor deficit and performance of Their side of body, possibly owing to reduction in cerebral activation as a rehabilitation, education and practical skills including maintaining body balance [16]. However, they did not observe any significant difference between left (P >0.05) and right hemiparesis (P > 0.05), which contradicts the findings of Clarks et al [32], who, like Begbic JV [14], reported that performance of right sided hemiplegics was greater (muscular) than that of left sided. But, this was again, not found consistent with Alonate et al [33] -the finding of which may not be similar to others because of neglecting syndrome and general/muscular weakness (grade-3) and because they had osteoarthritis (in knee/other joints) and used a cane.…”

Stroke affects body-balance performance in elderly who falls. Best-suited-rehabilitation for post-stroke/ hemiplegics (PSH) patients depends on the accuracy and reliability of methods in assessing their static body balance. This prospectively designed single blinded study was conducted to compare the outcome of balance assessment among male PSH patients between quantitative (computerized Balance Master System: BMS) and qualitative (Tinetti`s Balance & Mobility Subscale Score: TBMS and Barthel Index Score: BIS) methods. Data were analyzed using SPSS Windows 12.0. Results of BMS and TBMS/BIS methods demonstrated high interrater-reliability and concurrent validity of findings based on Limit of Stability(LOS) and Target Sway(TS) tests, when performed on a foam-platform to assess 3 types of sensory organization tests: eyeopen(EO), eye-closed(EC) & central-target(CT). Mean post-stroke duration of 30 patients studied was 10.7+-8.6 weeks from onset. Of them (mean age 62.3±14.5years), 90% sustained a cerebral infarction and 10% hemorrhage. And, 53% had a right while 47% had left-sided hemiplegia. While, TBMS correlated with BIS, positively (r=0.83, p<0.01), it correlated with BMS negatively, in terms of (i) LOS for EO (r=-0.36,p<0.03), and, EC (r=-0.35,p<0.03) on foam platforms; and (ii) CT for TS (r=-0.48,p<0.001) on firm platform. Similarly, BIS was negatively correlated with BMS: in terms of (i) LOS of EO performed on foam platform (r=-0.41,p<0.012) and (ii) LOS of EC (r=-0.30, p<0.05) and CT/TS of EC(r=-0.40,p<0.01), both performed on firm platform. However, a highly positive correlation existed among all BMS findings: with EC LOS (r=0.721,p<0.01)] and E0 LOS (r= 0.0.604,p<0.001) correlated on both firm and foam platforms.In conclusion, BMS method proved to be more reliable and valid in LOS parameters including TS for CT, than qualitative assessments of TBMS and BIS. Moreover, findings of BMS is not affected by the psychological aspects of the therapist carrying on the test on PSH-patients which may confounded the findings of qualitative analytic methods.

“…Of specific note are the overall decreases in max excursion and directional control in each of the eight trials, specifically when attempting to move in the backward direction. Decreased values of any of the parameters can predict an increased fall risk, instability during weight-shifting activities, and inability to perform weight-shifting activities [48,49]. The NeuroCom LOS test has shown a test-retest reliability ranging from high to low across the LOS measures (ICC2,k 0.82 to 0.48) and concurrent and construct validity of the LOS tests are not definitively established [50].…”

Methodology and demographics of a single blinded, randomized controlled trial of chiropractic compared to physical therapy for balance impairments in community dwelling geriatric patients with or without low back pain

Background: Postural control problems effect between 28% and 35% of individuals over the age 65 and increases with age. Musculoskeletal pain in the elderly impacts 20% to 49% of people between the ages of 65 and 75, is a leading falls risk factor, and a robust predictor of morbidity. Polypharmacy in the management of chronic pain is common in the geriatric population. Conservative treatment options for balance and back pain are underrepresented in scientific literature.
