Axial motor impairments are a common cause of disability in patients with Parkinson's disease, become more prominent with longer disease duration, and have been said to be less responsive to levodopa replacement therapy. The ability to turn in bed while lying supine before and after dopaminergic stimulation was studied in a group of 36 patients with Parkinson's disease; 23 were in Hoehn and Yah...

OBJECTIVE In previous studies about the control of posture there have been controversial findings. Our aim was to examine the role of monocular and binocular vision in controlling posture in quiet stance. METHODS Twenty-eight normal subjects were tested. We used a force platform in measuring postural stability. In main experiment, postural stability was measured in four conditions: both eyes ...

Introduction. Improvement of postural stability is an important goal during poststroke rehabilitation. Since weight-bearing asymmetry (WBA) towards the nonparetic leg is common, training of weight-bearing symmetry has been a major focus in post-stroke balance rehabilitation. It is assumed that restoration of a more symmetrical weight distribution is associated with improved postural stability. ...

BACKGROUND Studies of human upright posture typically have stressed the need to control ankle and hip joints to achieve postural stability. Recent studies, however, suggest that postural stability involves multi degree-of-freedom (DOF) coordination, especially when performing supra-postural tasks. This study investigated kinematic synergies related to control of the body's position in space (tw...

introduction: genu varum is considered a risk factor for knee osteoarthritis. being aware of postural swing changes in various standing positions among genu varum patients, provide insight to prevent osteoarthritis in this population. this study is undertaken to compare postural stability in various standing positions between young healthy and genu varum male individuals. materials and methods:...

objectives: altered movement strategy and postural control has been observed in low back pain (lbp) patients. objective of this study was to determine postural response following support surface translation, also correlations between postural response related measures and disability caused by lbp. methods: 20 healthy subjects and 20 patients with recurrent non specific lbp participated in this ...

PURPOSE This study assesses the postural stability and the effect of balance training using a force platform visual biofeedback among outpatients with postural disturbances following stroke. METHOD A tilting multiaxial force platform was used to assess bilateral postural stability in 38 outpatients (mean age 69.50  +/- 8.57 years) with hemiplegia and/or ataxia after stroke. Stability indexes ...

Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content o...

We aimed to investigate the characteristics of Parkinsonian features assessed by the unified Parkinson's disease rating scale (UPDRS) and determine their correlations with the computed tomography (CT) findings in patients with idiopathic normal pressure hydrocephalus (iNPH). The total score and the scores for arising from chair, gait, postural stability, and body hypokinesia in the motor examin...

BACKGROUND AND PURPOSE Although cerebral white matter lesions (WMLs), silent infarcts (SIs), and microbleeds (MBs) are individually associated with poorer gait and balance, it is unknown if they interact. We studied the interactions of WML volume with SI and MB on gait and postural stability. METHODS Participants in a population-based study aged 60 to 86 years underwent brain MRI, computerize...
