“…It is well documented that body sway characteristics assessed via center-of-pressure (CoP) analysis are sensitive to changes associated with ageing [14][15][16]. Moreover, CoP measures have also been associated with an increased risk of falling [17] and fall history [18,19] in older adults. Since the assessment of body sway is time-consuming and potentially expensive, various non-instrumented tests have been proposed as an alternative.…”

Diagnostic Balance Tests for Assessing Risk of Falls and Distinguishing Older Adult Fallers and Non-Fallers: A Systematic Review with Meta-Analysis

Falls are a major cause of injury and morbidity in older adults. To reduce the incidence of falls, a systematic assessment of the risk of falling is of paramount importance. The purpose of this systematic review was to provide a comprehensive comparison of the diagnostic balance tests used to predict falls and for distinguishing older adults with and without a history of falls. We conducted a systematic review of the studies in which instrumented (force plate body sway assessment) or other non-instrumented balance tests were used. We analyzed the data from 19 prospective and 48 retrospective/case-control studies. Among the non-instrumented tests, the single-leg stance test appears to be the most promising for discrimination between fallers and non-fallers. In terms of body sway measures, the center-of-pressure area was most consistently associated with falls. No evidence was found for increased benefit of the body sway test when cognitive tasks were added, or the vision was eliminated. While our analyses are limited due to the unbalanced representation of different test and outcome measures across studies, we can recommend the single-leg test for the assessment of the risk of falling, and the measurements of body sway for a more comprehensive assessment.

“…These changes in postural sway were sensitively identified by IMU. Wearable sensors are widely being used for investigating fall risk assessment and fall predictions (Frames et al, 2018;Lockhart, Frame, Soangra, & Lach, 2014). Wearable sensors will be helpful to clinicians to identify patients with high fall risk and guide interventions to prevent falls in acute -care settings.…”

Postural sway analysis is an important tool in fall risk analysis. A traditional way to measure postural sway is through forceplates by mapping Center of Pressure (COP) excursions or tracking marker position using motion analysis camera system. However, these systems are expensive and lack portability to their usage in clinical environments. In this study, a wearable low-cost MEMS inertial sensor was developed and validated for its usage in postural sway assessment. This study had two important objectives 1) To develop and validate an Inertial Measurement Unit (IMU) for sway analysis 2) To assess the feasibility of IMU in detecting slight balance impairments due to reduced proprioception or induced subthreshold vibrations on the feet. Sway velocity, Root Mean Square (RMS), and sway path length could successfully differentiate postural changes due to varying proprioceptive and sub-threshold vibration conditions. Wearable sensors are easy-to-use, portable and accurate devices for postural sway assessment in clinics.

Objectives Walking and postural balance are extremely important to obtain food and to work. Both are critical for quality of life and ability to survive. While walking reflects musculoskeletal and cardiopulmonary systems, postural balance depends on body size, muscle tone, visual, vestibular and nervous systems. Since GH and IGF-I act on all these systems, we decided to study those parameters in a cohort of individuals with severe short stature due to untreated isolated GH deficiency (IGHD) caused by a mutation in the GHRH receptor gene. These IGHD subjects, despite reduction in muscle mass, are very active and have normal longevity. Methods In a cross-sectional study, we assessed walking (by a 6-min walk test), postural balance (by force platform) and fall risk (by the 'Timed Up and Go' test) in 31 IGHD and 40 matched health controls. Results The percentage of the walked distance measured in relation to the predicted one was similar in groups, but higher in IGHD, when corrected by the leg length. Absolute postural balance data showed similar velocity of unipodal support in the two groups, and better values, with open and closed eyes and unipodal support, in IGHD, but these differences became non-significant when corrected for height and lower-limb length. The time in 'Timed Up and Go' test was higher in IGHD cohort, but still below the cut-off value for fall risk. Conclusion IGHD subjects exhibit satisfactory walking and postural balance, without increase in fall risk.
