INTRODUCTION: Aim of the study was to characterize the clinical spectrum of long-term treated patients with Wilson's disease (WD) and to identify risk factors influencing long-term outcome. METHODS: In a cross-sectional study 30 WD-patients being treated for at least 2.5 and up to 31 years underwent a detailed clinical investigation, scoring of clinical findings yielding 7 motor and 3 non-motor subscores as well as laboratory testing. A factor analysis of these subscores and laboratory parameters was performed to detect those items with the highest influence on outcome, an ANOVA and subgroup analysis tested the influence of age, age at onset of diagnosis and duration of treatment on outcome...

Surgical reconstruction of peripheral nerves injuries with wide substance-loss is still a challenge. Many studies focused on the development of artificial nerve conduits made of synthetic or biological materials but the ideal device has not yet been identified. Here, we manufactured a conduit for peripheral nerve regeneration using a novel biodegradable hydrogel we patented that is oxidized polyvinyl alcohol (OxPVA). Thus, its characteristics were compared with neat polyvinyl alcohol (PVA) and silk-fibroin (SF) conduits, through in vitro and in vivo analysis...

Lameness is a clinical symptom associated with a number of sheep diseases around the world, having adverse effects on weight gain, fertility, and lamb birth weight, and increasing the risk of secondary diseases. Current methods to identify lame animals rely on labour intensive visual inspection. The aim of this current study was to determine the ability of a collar, leg, and ear attached tri-axial accelerometer to discriminate between sound and lame gait movement in sheep. Data were separated into 10 s mutually exclusive behaviour epochs and subjected to Quadratic Discriminant Analysis (QDA)...

BACKGROUND AND PURPOSE: Postural control declines with aging and is an independent risk factor for falls in older adults. Objective examination of balance function is warranted to direct fall prevention strategies. Force platform (FP) systems provide quantitative measures of postural control and analysis of different aspects of balance. The purpose of this study was to examine the reliability and validity of FP measures in healthy older adults. METHODS: This study enrolled 46 healthy elderly adults, mean age 67...

INTRODUCTION: Up to 20% of total knee arthroplasty patients remain unsatisfied post-surgery, and a large proportion of them report anterior knee pain. This study aims to verify whether patients who experience anterior knee pain after total knee arthroplasty (TKA) will exhibit kinematic characteristics similar to those associated with patellofemoral syndrome, including in the frontal and transverse planes. MATERIALS AND METHODS: Using four different assessment methods [radiological, patient-reported outcome, musculoskeletal assessment with functional performance testing, and a 3D kinematic assessment during gait], the clinical and 3D knee kinematic profiles of three groups were compared: a painful and an asymptomatic TKA group and a healthy control group...

CLINICAL/METHODICAL ISSUE: Foot pain is in the case of long-term congenital, acquired or posttraumatic foot deformities a relevant clinical problem. STANDARD RADIOLOGICAL METHODS: On the basis of the clinical findings and the orthopaedic question, radiographs of the foot while standing in two planes are supplemented by radiographs of the ankle in an anterior-posterior plane. The imaging diagnostics of the foot are based on the conventional X‑ray diagnostic workup and becomes even more precise and differentiated by the possibility of intersecting imaging procedures...

Robust gait segmentation is the basis for mobile gait analysis. A range of methods have been applied and evaluated for gait segmentation of healthy and pathological gait bouts. However, a unified evaluation of gait segmentation methods in Parkinson's disease (PD) is missing. In this paper, we compare four prevalent gait segmentation methods in order to reveal their strengths and drawbacks in gait processing. We considered peak detection from event-based methods, two variations of dynamic time warping from template matching methods, and hierarchical hidden Markov models (hHMMs) from machine learning methods...

OBJECTIVES: Patient-specific (PS) implantation surgical technology has been introduced in recent years and a gradual increase in the associated number of surgical cases has been observed. PS technology uses a patient's own geometry in designing a medical device to provide minimal bone resection with improvement in the prosthetic bone coverage. However, whether PS unicompartmental knee arthroplasty (UKA) provides a better biomechanical effect than standard off-the-shelf prostheses for UKA has not yet been determined, and still remains controversial in both biomechanical and clinical fields...

BACKGROUND: Improved walking is one of the highest priorities in people living with stroke. Post-stroke lower limb spasticity (PSLLS) impedes walking and quality of life (QOL). The understanding of the evidence of improved walking and QOL following botulinum toxin (BoNTA) injection is not clear. We performed a systematic review of the randomized control trials (RCT) to evaluate the effectiveness of BoNTA injection on walking and QOL in PSLLS. METHODS: We searched PubMed, Web of Science, Embase, CINAHL, ProQuest Thesis and Dissertation checks, Google Scholar, WHO International Clinical Trial Registry Platform, ClinicalTrials...

BACKGROUND: Sarcopenia (the age-related loss of muscle mass and function) is a major contributor to loss of mobility, falls, loss of independence, morbidity and mortality in older people. Although resistance training is effective in preventing and reversing sarcopenia, many older people are sedentary and either cannot or do not want to exercise. This trial examines the efficacy of supplementation with the amino acid leucine and/or angiotensin converting enzyme inhibition to potentially improve muscle mass and function in people with sarcopenia...

Seronegative myasthenia gravis (MG) is a generalized form of MG that is diagnosed on the basis of clinical symptoms, electrophysiological testing, and pharmacological responses, in the absence of a seropositive status for anti-acetylcholine receptor (AChR) antibodies. Generalized MG that is seronegative for anti-AChR, anti-muscle-specific kinase (MuSK), and anti-low density lipoprotein receptor related protein 4 (Lrp4) antibodies is known as triple-seronegative MG. We here describe a case of triple-seronegative MG in an 8-year-old boy...

Gait impairment in multiple sclerosis (MS) can result from muscle weakness, physical fatigue, lack of coordination, and other symptoms. Walking speed, as measured by a number of clinician-administered walking tests, is the primary measure of gait impairment used by clinical researchers, but inertial gait features from body-worn sensors have been proven to add clinical value. This paper seeks to understand and differentiate the physiological significance of four such features with proven value in MS to facilitate adoption by clinical researchers and incorporation in gait monitoring and analysis systems...

BACKGROUND: Dopa-responsive dystonia (DRD) is a clinical syndrome characterized by early onset dystonia and a dramatic response to relatively low doses of levodopa. The autosomal dominant DRD is caused by mutations in the gene coding GTP cyclohydrolase 1 (GCH1), the enzyme that catalyzes the first step in the biosynthesis of tetrahydrobiopterin. We herein report a novel gene mutation causally links to DRD. SUBJECT AND METHODS: A 23-year-old woman, presented with a history of gait abnormality and leg dystonia at age 15...
