“…We would expect noise-like effects to be relatively independent of the external sensory environment. The fact that elderly exhibited different coordination than young with visual sway-referencing, points instead at increased dependence on visual inputs as has been reported by others [1,27,28]. Manchester et al [12] noted that body sway was greater when subjects' eyes were open in the dark than when their eyes were closed.…”

We used multivariate kinematics and joint torque measurements during dynamic posturography to determine the relative contributions of changes in overall control gain, relative weighting of sensors, and noise-like effects on posture control in the elderly. Our results show that sway coordination and amplitude both change with age, but that changes in overall feedback gains do not explain these differences. We propose that increased sway of elderly subjects in platform sway-referenced conditions is due to sensory noise or decreased ability to detect small motions of the platform, while increased sway during visual sway-referencing is due to re-weighting of the various sensors.

“…It is well known that balance is impaired with increasing age (1,2) and with lower extremity pathology. Knee osteoarthritis (OA), one of the most common chronic health conditions, is associated with significant impairment and disability (3), and predominantly affects the elderly population (4).…”

Objective. To identify factors related to single-leg standing balance in individuals with medial compartment knee osteoarthritis (OA). Methods. This cross-sectional study assessed clinical, demographic, and biomechanical measures in 57 individuals and their relationships with single-leg standing balance. Differences in age, mass, symptoms, knee pain, radiographic severity, lower extremity alignment, and hip and knee extension as well as hip abduction torques were compared between those who could and could not perform 3 trials of single-leg standing balance. Multiple regression was used to identify predictors of center of pressure (COP) path length in those who could complete the task. Results. Thirty-four individuals (60%) successfully completed all 3 single-leg standing balance trials and were significantly younger (P ‫؍‬ 0.003) than those who could not. No other variable was significantly different between the groups. Disease severity, number of painful knees, lower extremity alignment, pain intensity, and quadriceps torque were all significant predictors of COP path length. Specifically, better single-leg standing balance (smaller COP path length) was related to more severe radiographic changes and stronger quadriceps, those with bilateral symptoms, and to less varus malalignment and knee pain. Conclusion. Single-leg standing balance in those with medial knee OA is related to the modifiable factors lower extremity alignment, knee pain, and quadriceps strength. Given the reduced balancing ability in this patient population, interventions targeting these factors are necessary.

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.
