Background: Postural instability has been identified as a fall risk factor with a significant impact on the quality of life of patients with Parkinson's disease (PD). The aim of this study was to compare the center of pressure (COP) between faller and nonfaller patients with PD during static standing.
Methods: Thirty-two faller patients and 32 nonfaller patients with PD participated in this study. All patients performed the static balance test on a force plate. COP data were recorded during quiet standing. Mean distance, sway area, mean velocity, mean frequency, and peak power were derived from the COP data. Statistical analysis was performed using independent -tests to compare faller and nonfaller patients.
Results: Fallers presented a greater average distance, wider sway area, faster average speed, and greater peak power than nonfallers ( < 0.05). In contrast, no significant group differences were observed in peak frequency and mean frequency ( > 0.05).
Conclusions: Although falls occur during dynamic activities, our study demonstrated that even a safe and simple static postural balance test could significantly differentiate between faller and nonfaller patients. Thus, these results suggest that quantitatively assessed static postural sway variables would be useful for distinguishing prospective fallers among PD patients.

Introduction: The cerebellum is a common lesion site in persons with multiple sclerosis (PwMS). Physiologic and anatomic studies have identified a topographic organization of the cerebellum including functionally distinct motor and cognitive areas. In this study, a recent parcellation algorithm was applied to a sample of PwMS and healthy controls to examine the relationships among specific cerebellar regions, fall status, and common clinical measures of motor and cognitive functions.

: Falls and fall consequences in older adults are global health issues. Previous studies have compared postural sways or stepping strategies between older adults with and without fall histories to identify factors associated with falls. However, more in-depth neuromuscular/kinematic mechanisms have remained unclear.

Objective: To determine whether hip flexion (HF), extension (HE), abduction (HA), knee flexion (KF) and extension (KE), and ankle plantarflexion (APF) and dorsiflexion (ADF) Maximum Voluntary Contraction (MVC) differentiates between non-fall and fall history in persons with MS (PwMS) after accounting for age, gender, fatigue, disability, and disease duration.
Design: Secondary analysis of a cross-sectional study.
Setting: Community-based comprehensive MS Center PARTICIPANTS: 172 persons with MS who completed a one-time visit INTERVENTIONS: Not applicable MAIN OUTCOME MEASURES: Lower limb (LL) MVC was measured for each muscle group as isometric peak torque (Newton-meter: Nm) of both limbs (Strongest: S; Weakest: W) using a Biodex Dynamometer and normalized by body weight (Nm/kg).

: Persons with multiple sclerosis (MS) experience changes in balance, such as poor and reactive stepping, as well as altered fall-related psychological factors, such as increased concern about falling and feared consequences about falling. Such concerns and fear may relate to and influence mobility. However, these relations are poorly understood in people with MS.
