BACKGROUND: In traditional societies, patients who reach adulthood with developmental dysplasia of the hip (DDH) may be labeled "disabled" and may be considered "defective," causing them psychologic pain and problems with social interactions. In some patriarchal societies, women disproportionately experience these problems, because they may be seen as insufficient in terms of marriage and sexual intercourse owing to hip-related limitations, and they may be married through arranged marriages to people who also have disabilities...

BACKGROUND: Impaired physical performance is highly prevalent in older cancer patients and is associated with cancer-related outcomes such as mortality and chemotherapy-related toxicity. Physical performance might already decline prior to the cancer diagnosis due to undiagnosed disease. This study aimed to assess whether the physical performance of community-dwelling individuals prior to cancer diagnosis is worse compared to matched controls who are not diagnosed with cancer. METHODS: The study sample was selected from the Longitudinal Aging Study Amsterdam, a longitudinal study on a nationally representative sample of the Dutch older population...

During continuous uphill walking (UW) or downhill walking, human locomotion is modified to counteract the gravitational force, aiding or impeding the body's forward momentum, respectively. This study aimed at investigating the center of mass (COM) and center of pressure (COP) velocities and their relative distance during the transition from uphill to downhill walking (UDW) to determine whether locomotor adjustments differ between UDW and UW. Fourteen participants walked on a triangular slope and a continuous upslope of 15°...

Cognition and gait appear to be closely related. The chronological interplay between cognitive decline and gait dysfunction is not fully understood. The aim of the present prospective study is investigating whether the dysfunction of specific gait parameters, during specific task and medication conditions, may predict subsequent cognitive impairment in Parkinson's disease (PD). We evaluated cognition and gait in 39 Parkinsonian patients at an initial assessment and after 3 years. Cognitive performance was evaluated with a neuropsychological battery designed to assess memory, executive/attention, and visuospatial domains...

Brain-machine interfaces (BMIs) have been used to incorporate the user intention to trigger robotic devices by decoding movement onset from electroencephalography (EEG). Active neural participation is crucial to promote brain plasticity thus to enhance the opportunity of motor recovery. This study presents the decoding of lower-limb movement-related cortical potentials (MRCPs) with continuous classification and asynchronous detection.We executed experiments in a customized gait trainer where 10 healthy subjects performed self-initiated ankle plantar flexion...

INTRODUCTION: Extrapyramidal deficits are poorly characterised in amyotrophic lateral sclerosis (ALS) despite their contribution to functional disability, increased fall risk and their quality-of-life implications. Given the concomitant pyramidal and cerebellar degeneration in ALS, the clinical assessment of extrapyramidal features is particularly challenging. OBJECTIVE: The comprehensive characterisation of postural instability in ALS using standardised clinical assessments, gait analyses and computational neuroimaging tools in a prospective study design...

Background: Motoric Cognitive Risk (MCR) syndrome is a pre-dementia syndrome characterized by slow gait and cognitive complaint that predicts both Alzheimer's disease and vascular dementia. Yet, we know very little about the brain structures and brain pathologies associated with MCR. The aim of this study was to identify gray matter networks associated with MCR. Methods: We used voxel-based morphometry and multivariate covariance-based statistics to identify gray matter networks associated with MCR in a pooled sample of 267 older adults without dementia from three different cohorts - two North American cohorts and one French cohort...

BACKGROUND: With the growing number of young-older adults (baby-boomers), there is an increasing demand for assessment tools specific for this population, which are able to detect subtle balance and mobility deficits. Various balance and mobility tests already exist, but suffer from ceiling effects in higher functioning older adults. A reliable and valid challenging balance and mobility test is critical to determine a young-older adult's balance and mobility performance and to timely initiate preventive interventions...

BACKGROUND: The feet make the initial contact with the ground when walking and critically control both posture and gait. Claw toe, a structural change in the foot that may develop after stroke, triggers functional changes affecting both the lower limbs and balance. OBJECTIVE: We analyzed the effects of a toe spreader on foot pressure and gait in chronic stroke patients. METHODS: We enrolled 25 stroke patients. We used Gaitview AFA-50 and GAITRite instruments to measure plantar pressure distribution and gait with and without a tow spreader...

OBJECTIVE: We investigated if anodal transcranial direct current stimulation (A-tDCS), applied over the supplementary motor areas (SMAs), could improve gait initiation in Parkinson's disease (PD) with freezing of gait (FOG). METHODS: In this double-blinded cross-over pilot study, ten PD with FOG underwent two stimulation sessions: A-tDCS (1 mA, 10 min) and sham stimulation. Eight blocks of gait initiation were collected per session: (1) pre-tDCS, with acoustic cueing; (2) pre-tDCS, self-initiated (no cue); and (3-8) post-tDCS, self-initiated...

Importance: It is important to know whether recovery of the vestibuloocular reflex (VOR) as measured by the video head impulse test (vHIT) is associated with the recovery of dynamic balance. It is also critical to know how much change in VOR gain is clinically relevant for establishing the recovery of dynamic balance. Objectives: To investigate the association between improved VOR gain as measured by the vHIT and improved dynamic balance (reduced fall risk) as measured by the dynamic gait index (DGI) and to calculate the minimal clinically important difference of VOR gain...
