The age-related decline in functional capability is preceded by a reduction in muscle quality. The purpose of this study was to assess the combined effects of progressive resistance training (PRT) and protein supplementation beyond habitual intakes on upper leg lean tissue mass (LTM), muscle quality and functional capability in healthy 50-70 years women. In a single-blinded, randomized, controlled design, 57 healthy older women (age 61.1 ± 5.1 years, 1.61 ± 0.65 m, 65.3 ± 15.3 kg) consumed 0.33 g/kg body mass of a milk-based protein matrix (PRO) for 12 weeks...

During aging, the prefrontal cortex (PFC) undergoes age-dependent neuronal changes influencing cognitive and motor functions. Motor-learning interventions are hypothesized to ameliorate motor and cognitive deficits in older adults. Especially, video game-based physical exercise might have the potential to train motor in combination with cognitive abilities in older adults. The aim of this study was to compare conventional balance training with video game-based physical exercise, a so-called exergame, on the relative power (RP) of electroencephalographic (EEG) frequencies over the PFC, executive function (EF), and gait performance...

A 62-year-old man with a 1-year history of numbness of the extremities, clumsiness, and gait disorder was diagnosed with cervical spondylotic myelopathy at a neighboring clinic and referred to our institution for surgery. The patient had undergone a total gastrectomy 6 years previously. Flattening of the cervical cord, associated with diffuse cervical spondylosis and intramedullary intensity change, was observed on magnetic resonance imaging of the cervical spine. Neurological examination revealed decreased vibratory and position sense in all limbs, with posterior funiculus-based neurological symptoms...

BACKGROUND: Reduced lower extremity range of motion (ROM) and muscle strength are related to functional disability in older adults who cannot perform one or more activities of daily living (ADL) independently. The purpose of this study was to determine which factors of seven lower extremity ROMs and two muscle strengths play dominant roles in the physical performance of community-dwelling older women. METHODS: Ninety-five community-dwelling older women (mean age ± SD, 70...

Cervical spinal cord injury (cSCI) occurs in over half of all cases of traumatic SCI, yet we lack therapies that can generate significant functional recovery in these patients. The development of animal models of cSCI will aid in the pre-clinical assessment of therapies and in understanding basic pathophysiological mechanisms. Here we describe a clinically relevant model of cervical contusion-compression injury in the mouse. Using a modified aneurism clip we generated a bilateral, incomplete injury that mimics contusion-compression injuries most commonly seen in humans...

OBJECTIVE: To determine whether brain activity over the prefrontal cortex measured in real time during walking predicts falls in high-functioning older adults. METHOD: We examined166 older persons (mean age 75 years, 51% women) enrolled in a prospective aging study. High-functioning status defined as the absence of dementia or disability with normal gait diagnosed by study clinicians. The magnitude of task-related changes in oxygenated hemoglobin levels over the prefrontal cortex was measured with functional near-infrared spectroscopy during motor (walking at normal pace) and cognitive (reciting alternate letters of the alphabet) single tasks and a dual-task condition (walking while reciting alternate letters of the alphabet)...

INTRODUCTION: The use of forced-swim, rat-validated cognition tests in mouse models of Traumatic Brain Injury (TBI) raises methodological concerns; such models are vulnerable to a number of confounding factors including impaired motor function and stress-induced non-compliance (failure to swim). This study evaluated the ability of a Radial Water Tread (RWT) maze, designed specifically for mice, that requires no swimming to distinguish mice with controlled cortical impact (CCI) induced TBI and Sham controls...

Myelination, the process by which oligodendrocytes form the myelin sheath around axons, is key to axonal signal transduction and related motor function in the central nervous system (CNS). Aging is characterized by degenerative changes in the myelin sheath, although the molecular underpinnings of normal and aberrant myelination remain incompletely understood. Here we report that axon myelination and related motor function are dependent on BubR1, a mitotic checkpoint protein that has been linked to progeroid phenotypes when expressed at low levels and healthy lifespan when overabundant...

Stroke is one of the most common causes of death and disability both in Poland and around the world. Each year, 250 out of 100,000 people in Europe are diagnosed with a disruption of cerebral perfusion in the form of stroke. In Poland, approximately 65,000-70,000 people are affected each year, with the incidence steadily increasing. Stroke survivors suffer from impaired cognitive and motor functions. Moreover, they exhibit severe gait pattern abnormalities, which together with balance disorders, constitute the main factors increasing the risk of falls in this patient group...

BACKGROUND: Haemophilia A is the cause of diverse musculoskeletal disorders such as ankylosis, arthritis and associated angular deformity. There are few reported cases in patients with haemophilia A in which simultaneous supracondylar femoral osteotomy and knee joint replacement has been performed to treat knee angular deformity and ankylosis. Here we present the case of an 18year old male patient, with an evolution of two years, who was unable to walk due to the presence of an untreated supracondylar fracture in the left femur and ipsilateral haemophilic arthropathy which led him to develop an ankylosis in flexion close to 70°...

To conduct a meta-analysis of clinical trials that examined the effect of music-supported therapy on stroke-induced motor dysfunction, comprehensive literature searches of PubMed, Embase and the Cochrane Library from their inception to April 2016 were performed. A total of 10 studies (13 analyses, 358 subjects) were included; all had acceptable quality according to PEDro scale score. The baseline differences between the two groups were confirmed to be comparable. Compared with the control group, the standardized mean difference of 9-Hole Peg Test was 0...

Although liver transplant for decompensated cirrhosis secondary to Wilson disease is well accepted, the use of transplant for patients with severe neurologic manifestations of this condition remains controversial, and these can be perceived as a contraindication. Here, we describe a 45-year-old woman who presented with an incidental hepatocellular carcinoma at the time of transplant. The patient had severe neurologic manifestations of Wilson disease pretransplant, including dysarthria, hyperreflexia, asymmetrical ataxia, tremor, bradyphrenia, and shuffling gait...

Since functional imaging of whole body movements is not feasible with functional magnetic resonance imaging (fMRI), the present study presents in vivo functional near-infrared spectroscopy (fNIRS) as a suitable technique to measure body movement effects on fronto-temporo-parietal cortical activation in single and dual task paradigms. Previous fNIRS applications in studies addressing whole body movements were typically limited to the assessment of prefrontal brain areas. The current study investigated brain activation in the frontal, temporal and parietal cortex of both hemispheres using functional near-infrared spectroscopy (fNIRS) with two large 4 x 4 probe-sets with 24 channels each during single and dual gait tasks...

BACKGROUND: Functional gait is an integral part of life, allowing individuals to function within their environment and participate in activities of daily living. Gait assessment forms an essential part of a physical examination and can help screen for physical impairments. No three-dimensional (3D) gait analysis studies of children have been conducted in South Africa. South African gait analysis laboratory protocols and procedures may differ from laboratories in other countries, therefore a South African data base of normative values is required to make a valid assessment of South African children's gait...

While healthy gait is often characterized as, or assumed to be symmetric, consistent asymmetries often exist. In this study, we test the hypotheses that asymmetries in lower limb function, as measured by ground reaction force characteristics, may be explained by differences in foot orientation or limb dominance. Peak ground reaction force (GRF) measurements, and impulses were obtained for thirty-six healthy subjects with simultaneous kinematic estimates of foot posture. Three gait tasks were performed: subjects walked i) with normal foot orientation, ii) with feet laterally rotated (outward), and iii) with feet aligned in the direction of movement (straight)...
