“…These authors also observed that in less affected patients (H&Y I), the CoP was shifted backwards, and in the most severely affected patients (H&Y III), the CoP was shifted forward as a consequence of a more stooped position. These previous studies reported an impaired ability of PD patients to lean forwards and backwards in voluntary tasks [18,27]. The visual information is not critical to the maintenance of balance during standing, it assumes greater importance with balance task complexity, or sensory input manipulation [28], as can been found with the use of unstable surfaces (foam).…”

“…The Computerized Dynamic Posturography (CDP) has already proven to be useful for balance evaluation of PD patients [10,17] giving insights into the physiological correlates of postural stability, [18] and gait [19]. Different studies refer that quantitative measures are not correlated with other clinical scores listed (e.g., duration of the disease and UPDRS) [20], or weakly correlated with H&Y stages, [17].…”

“…Different studies refer that quantitative measures are not correlated with other clinical scores listed (e.g., duration of the disease and UPDRS) [20], or weakly correlated with H&Y stages, [17]. Several studies have analyzed the postural sway characteristics of PD patients compared with age-matched controls [21,18,22], nevertheless changes of the posturographic parameters as a function of the disease severity have not been very well studied. In this study, we focused our attention on the analysis of the variation of postural behavior parameters extracted from CoP time series presented at different stages established by clinical scales.…”

Abstract-Progression of Parkinson disease (PD) increasessevere motor symptoms such as bradykinesia, tremor, gait disturbance and postural instability, interfering with patients' daily life autonomy. Clinical evaluation is based on specific Scales like Hoehn & Yahr (H&Y) or UPDRS scales. The main goal of the study was to identify motor changes in the kinematic parameters related to different stages of Parkinson's disease progression according to H&Y scale. A secondary goal was to determine more objectively the stage of the disease reducing the discomfort of scales subjectivity. Our sample integrated 103 patients (45 female and 58 male, 70.5±8.4 years) diagnosed with PD by neurologists specialized in movement disorders. Postural Behavior was evaluated using Computerized Dynamic Posturography equipment (Balance Master System). Postural behavior was based on posturographic analysis of the center of pressure (CoP) time series (corresponding to the vertical projection of the center of gravity) to determine kinematic parameter(s) considered suitable to identify postural behavior modification. The posturographic tests applied were: 1) modified Clinical Test of Sensory Interaction on Balance (mCTSIB); 2) Limits of Stability (LOS); 3) Rhythmic Weight Shift (RWS). The results, concerning four stages of the H&Y scale (I-IV), showed significant differences between groups/stages. Static balance parameters like velocity, total distance, amplitude and frequency of CoP sway, increase with disease severity. In early to medium stages (I-II) of the disease, CoP presents a projection backwards, while in stage IV, this projection showed a trend to change forwards. Concerning dynamic balance, LOS presents a reduction mainly in the forward direction in all stages. The directional control in anterior-posterior RWS decreases with disease progression.

“…These tasks are also relevant because they can test the dynamic nature of postural control (e.g., maximum amplitude and velocity of body motions) that cannot be analyzed in quiet stance. In the literature, reports of ML LOS and ML RWS performance in patients with PD are rare (see Ganesan et al 2010;Rossi et al 2009;Vervoort et al 2013;Yang et al 2008). Mostly, these studies showed disease-related impairments in performance in both tasks (amplitude, velocity) and in variability of performance in the ML LOS task.…”

“…In the comparison between patients and elderly control subjects, we expected to find disease-related impairments when performing the ML RWS and ML LOS tasks (amplitude, velocity, and/or directional control; cf. Ganesan et al 2010;Rossi et al 2009;Vervoort et al 2013;Yang et al 2008) and in the contribution of the ML postural control mechanisms as causal factors. These disease-related effects should be detected because the LOS and RWS tasks are very challenging.…”

Patients with Parkinson's disease display impairments of postural control most particularly in active, challenging conditions. The objective of the present study was to analyze early signs of disease-related and also age-related impairments in mediolateral body extension and postural control. Fifty-five participants (18 Hoehn and Yahr stage 2 patients in the off-drug condition, 18 healthy elderly control subjects, and 19 young adults) were included in the study. The participants performed a quiet stance task and two active tasks that analyzed the performance in mediolateral body motion: a limit of stability and a rhythmic weight shift task. As expected, the patients displayed significantly lower and slower body displacement (head, neck, lower back, center of pressure) than elderly control subjects when performing the two body excursion tasks. However, the behavioral variability in both tasks was similar between the groups. Under these active conditions, the patients showed significantly lower contribution of the hip postural control mechanisms compared with the elderly control subjects. Overall, the patients seemed to lower their performance in order to prevent a mediolateral postural instability. However, these patients, at an early stage of their disease, were not unstable in quiet stance. Complementarily, elderly control subjects displayed slower body performance than young adults, which therefore showed an additional age-related impairment in mediolateral postural control. Overall, the study illustrated markers of age-related and Parkinson's disease impairments in mediolateral postural control that may constrain everyday activities in elderly adults and even more in patients with Parkinson's disease.

Clinical and posturographic correlates of falling in Parkinson's disease

et al. 2013

Various clinical tests and balance scales have been used to assess postural stability and the risk of falling in patients with idiopathic Parkinson's disease (IPD). Quantitative posturography allows a more objective assessment but the findings in previous studies have been inconsistent and few studies have investigated which posturographic measures correlate best with a history of falling. The purpose of this study was to determine the efficacy of clinical tests, balance scales, and stable-platform posturography in detecting postural instability and discriminating between fallers and non-fallers in a home-dwelling PD cohort. Forty-eight PD subjects (Hoehn & Yahr stage 1-3) and 17 age-matched controls had the following assessments: Activities-specific Balance Confidence scale, Berg Balance Scale, Unified Parkinson's Disease Rating Scale (UPDRS) (motor), pull-test, timed up-and-go, static posturography, and dynamic posturography to assess multidirectional leaning balance. Of the clinical assessments, all but the pull-test were closely correlated with a history of falling. Static posturography discriminated between PD fallers and controls but not between PD fallers and non-fallers, whereas dynamic posturography (reaction time, velocity, and target hit-time) also discriminated between fallers and non-fallers. Our findings suggest that this combination of clinical and posturographic measures would be useful in the prospective assessment of falls risk in PD patients. A further prospective study is now required to assess their predictive value. © 2013 Movement Disorder Society.
