“…On the other hand, this significantly lower contribution of the ML body weight distribution mechanism was present in the RWS and LOS tasks even in patients at an early stage of their disease. Hence, this result confirmed previous reports evidencing physiological diseaserelated impairments at the hip level (Bridgewater and Sharpe 1998;Wright et al 2007) and impairments in trunk movement and axial rotation (Adkin et al 2005;Carpenter et al 2004;Horak et al 2005). Our results showed that the ML body weight distribution mechanism was weaker in patients with PD than in control subjects.…”

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.

“…The sensor was positioned at the level of the lower back (lumbar 2-3) near to the body's centre of mass (Adkin, Bloem, & Allum, 2001;Warrenburg et al, 2005), see Figure 1. For the feet, the bases of the two MTx units are positioned and oriented over the dorsum of feet.…”

“…symmetry axis of the platform on which the participants stood, and the other two axes were perpendicular to the sagittal axis with respect to the earth's gravity. The MTx unit was placed on patient's trunk in accordance with Ochi, Abe, Ishigami, Orsu, & Tomita (1997), Adkin et al (2001) and Warrenburg, Figure 1. The gyroscope sensors (MTx units) used to measure the trunk and feet angular movements 2-D space (Deza & Deza, 2013) collected during the trial, given by Teranishi et al (2011): where the data point P n = (α n , β n ) at time n and the data point P n-1 = (α n-1 , β n-1 ) at time n-1.…”

“…These angles can be used to study the orientation of body segments, whose orientation is result of a complex kinematic chain. Therefore, the pitch, roll and yaw angles are also used in medicine (Adkin, Bloem, & Allum, 2001;Allum, Adkin, Carpenter, Held-Ziolkowska, Honegger, & Pierchala, 2001;Gill et al, 2001). In these studies, pitch and roll sway measurements during specific balance tasks identified differences in balance control in patients (Pts), compared to those of healthy subjects (HS).…”
