OBJECTIVE To validate the freezing of gait questionnaire (FOG-Q) for a Brazilian population of Parkinson's disease (PD) patients. METHODS One hundred and seven patients with a diagnosis of PD were evaluated by shortened UPDRS motor scale (sUPDRm), Hoehn and Yahr (HY), Schwab and England scale (SE), Berg balance scale (BBS), falls efficacy scale international (FES-I), gait and balance scale (G...

The primary aim of this study was to assess the correlations between gait analysis, magnetic resonance imaging (MRI), and Gross Motor Function Measure (GMFM) scores in children with cerebral palsy (CP). These common diagnostic tools were used to evaluate 21 children affected by CP (mean age: 6 years, range: 5-13 years; 8 females and 13 males; 5 left hemiplegics, 4 right hemiplegics, 12 diplegic...

Our goal is to establish a simple baseline method for human identification based on body shape and gait. This baseline recognition method provides a lower bound against which to evaluate more complicated procedures. We present a viewpoint dependent technique based on template matching of body silhouettes. Cyclic gait analysis is performed to extract key frames from a test sequence. These frames...

OBJECTIVE To compare knee kinematics and kinetics during walking in patients with posttraumatic versus nontraumatic medial compartment knee osteoarthritis (OA). METHODS Participants with medial compartment knee OA were classified as nontraumatic (n = 122) or posttraumatic (n = 93) based on evidence of previous anterior cruciate ligament tear, confirmed arthroscopically. Kellgren/Lawrence seve...

OBJECTIVES We tested whether intermittent short-radius centrifugation was effective for mitigating alteration in balance and gait following bed rest. METHODS Ten male subjects were exposed to 5 days of 6° head-down tilt bed rest with: (a) no countermeasure; (b) daily 1-g centrifugation for a continuous 30-min period; and (c) daily 1-g centrifugation for six periods of 5 min. During and after ...

BACKGROUND Recently, the concept of motoric cognitive risk (MCR) syndrome was proposed, where slow gait is considered a risk factor for conversion to dementia. AIM To retrospectively investigate the characteristics of MCR among a population aged 75+ years, focusing on the aspects of epidemiology and neurobehavioral characteristics. METHOD The participants were 590 residents aged 75+ years l...

BACKGROUND AND PURPOSE Our aims were to analyze the characteristics of parkinsonian features and to characterize changes in parkinsonian motor symptoms before and after the cerebrospinal fluid tap test (CSFTT) in idiopathic normal-pressure hydrocephalus (INPH) patients. METHODS INPH subjects were selected in consecutive order from a prospectively enrolled INPH registry. Fifty-five INPH patien...

Chorea may contribute to balance problems and walking difficulties that lead to higher fall rates in individuals with Huntington's disease (HD). Few studies have examined the effects of tetrabenazine (TBZ), an anti-choreic drug, on function and mobility in HD. The purpose of this study was to compare: 1) gait measures in forward walking, 2) balance and mobility measures, and 3) hand and forearm...

OBJECTIVE To assess the sensations of instability that many patients report after traumatic brain injury (TBI). DESIGN A controlled study. SETTING A motion analysis and vestibular and balance laboratory. PARTICIPANTS Twenty subjects, 10 with TBI and complaints of instability, and 10 without TBI. INTERVENTIONS Balance and gait analysis. MAIN OUTCOME MEASURES Dizziness Handicap Inventor...

OBJECTIVE To evaluate reported fatigue levels and gait deficits in patients with multiple sclerosis (MS) to determine the relationships that may exist between fatigue in patients with MS and alterations in gait mechanics. DESIGN Cross-sectional. SETTING Biomechanics laboratory. PARTICIPANTS Subjects with MS (n=32) and age- and sex-matched controls (n=30). INTERVENTIONS None. MAIN OUTC...
