BACKGROUND: Rehabilitation programmes are used to improve hip fracture outcomes. There is little published trial clinical trial or population-based data on the effects of the type or provider of rehabilitation treatments on hip fracture outcomes. We evaluated the associations of rehabilitation interventions with post-operative hip fracture outcomes. METHODS: Cross-sectional (2013-2015) analysis of data from the English National Hip Fracture Database (NHFD) from all 191 English hospitals treating hip fractures...

This inborn error of manganese metabolism has only recently been identified. A total of 28 affected individuals from ten families are known worldwide. Mutations in SLC39A14, encoding a Mn uptake transporter, have recently been recognized to cause excessive Mn concentrations in the blood which is believed to be neurotoxic and lead to a parkinsonian-like movement disorder caused by accumulation of Mn in the basal ganglia. We are reporting a new variant of SLC39A14 gene mutation (OMIM 608736 8p21.3) that has never been described in the literature so far...

PURPOSE: To modify the Performance-Oriented Mobility Assessment-Gait (POMA-G) subtest and validate this modified POMA-G (mPOMA-G) in children with hypophosphatasia (HPP), a rare metabolic disorder that can manifest with musculoskeletal symptoms that impair mobility and ambulation. METHODS: Based on feedback from an expert panel, the POMA-G was modified by removing gait initiation/path assessments and expanding the rating scale for step length/continuity to capture aspects of observational gait analysis relevant to children with HPP...

The patient was a Japanese woman who experienced a decrease in activity and gait disturbance as the initial symptoms at the age of 86, followed by disorientation and memory dysfunction. Magnetic resonance imaging showed extensive cortical regions with hyperintensity in diffusion-weighted images, and these regions showed swelling in T2-weighted and fluid-attenuated inversion recovery (FLAIR) images. The medial occipital cortex and striatum showed no apparent hyperintensity on diffusion-weighted imaging (DWI)...

BACKGROUND: Walking on inclined surfaces is an everyday task, which challenges stability and propulsion even in healthy adults. Children with cerebral palsy adapt similarly to inclines like healthy children do. However, how stability and propulsion in these subjects are influenced by different inclines remained unaddressed as of yet. RESEARCH QUESTION: The aim was to examine the feeling of safety, stability and propulsion of children with cerebral palsy when walking on inclines to gain insight into the challenges they might face on these conditions...

BACKGROUND: Previous research has demonstrated clear associations between specific running injuries and patterns of lower limb kinematics. However, there has been minimal research investigating whether the same kinematic patterns could underlie multiple different soft tissue running injuries. If they do, such kinematic patterns could be considered global contributors to running injuries. HYPOTHESIS: Injured runners will demonstrate differences in running kinematics when compared with injury-free controls...

The pedunculopontine nucleus (PPN) is a reticular nucleus located in the mesencephalic and upper pontine tegmentum. Initially, characterized by its predominant cholinergic projection neurons, it was associated with the "mesencephalic locomotor region" and "reticular activating system". Furthermore, based on histopathological studies, the PPN was hypothesized to play a role in the manifestation of symptoms in movement disorders such as Parkinson's disease (PD). Since axial symptoms represent unmet needs of PD treatments, a series of pioneering experiments in Parkinsonian monkeys promoted the idea of a potential new target for deep brain stimulation (DBS) and much clinical interest was generated in the following years leading to a number of trials analysing the role of PPN for gait disorders...

Methylmercury (MeHg) is known to cause neurobehavioral impairment in human and experimental animals. We previously reported that MeHg (5 mg Hg/kg) induced severe neurobehavioral dysfunction in 4-week-old KK-Ay mice, although it is difficult to evaluate quantitatively the neurobehavioral impairment in MeHg-treated KK-Ay mice because of their obesity. The aim of this study was to evaluate MeHg-induced neurobehavioral dysfunction in KK-Ay mice using the dynamic weight-bearing test, which analyzes the animal's weight distribution between the four limbs...

BACKGROUND: Fampridine leads to significant walking improvements in many persons with multiple sclerosis (PwMS). However, a relevant proportion of PwMS does not respond to fampridine and predictors of initial drug responsiveness are unknown. METHODS: Drug response to prolonged-release (PR)-fampridine was assessed in 55 PwMS using the timed 25-foot walk (T25FW), the 6-minute walk test (6MWT) and the 12-item multiple sclerosis walking scale (MSWS-12) as outcome parameters...

BACKGROUND: Transtibial hydrocast sockets have been shown to be a potential alternative to hand-cast patella-tendon bearing sockets, the use of which would have particular benefits in under-resourced environments. However, data concerning wearer outcomes of hard hydrocast sockets (i.e. those without silicone liners), especially over long-term usage periods, is scarce in the literature. RESEARCH QUESTIONS: Are there any changes in wearer functional, spatio-temporal or satisfaction outcomes over a long usage period with a hydrocast socket? And how do the post-usage period outcomes compare with those from the wearers original prostheses? METHODS: In this pre-post interventional study, the clinical outcomes of twenty-one experienced transtibial prostheses users were evaluated using widely-accepted and employed methods to assess wearer functional capacity, mobility, gait and satisfaction...

Declining physical function is common among aging adults, however physical activity may decrease the rate of functional loss among adults with or at risk of developing osteoarthritis. Previous studies on this topic used subjective measures of physical activity and were subject to higher selection bias. This study employed propensity score matching techniques to reduce selection bias when measuring the association between objectively-measured physical activity and future physical function. 687 participants of the Osteoarthritis Initiative were included in either a physically active group (n=280) or a physically inactive group (n=407) according to baseline accelerometer data...

Corticospinal lesions cause impairments in voluntary motor control. Recent findings suggest that some degree of voluntary control may be taken over by a compensatory pathway involving the reticulospinal tract. In humans, evidence for this notion mainly comes from StartReact studies. StartReact is the acceleration of reaction times by a startling acoustic stimulus (SAS) simultaneously presented with the imperative stimulus. As previous StartReact studies mainly focused on isolated single-joint movements, the question remains whether the reticulospinal tract can also be utilized for controlling whole-body movements...

Purpose: To quantify the effects of an articulated ankle foot orthosis on genu recurvatum gait in adolescents with traumatic brain injury (TBI). Methods: Gait analysis was conducted in 2 individuals with TBI during over ground ambulation with (braced condition) and without (barefoot condition) the AAFO. For each participant, stride-by-stride gait data were compared to assess differences between barefoot and braced walking conditions. Results: During the braced versus barefoot condition, both participants demonstrated reduced plantar flexion at initial contact, increased knee flexion at initial contact, reduced peak knee extension during stance, and reduced peak and integral of internal knee flexor moment during stance...
