Due to the indistinct nature of symptoms for Cerebral Small Vessel Disease (CSVD), diagnosis is often missed. With significant deterioration of movement disorder, risk of falls increases dramatically.Comparison study was conducted to explore the association between balance function and gait instability, and the treatment effectiveness of visual feedback balance training on the gait disorder in CSVD patients.Fifty-six patients with CSVD were studied. They were randomly divided into observation and control groups, and were given conventional gait rehabilitation training, including single-leg weight, shift of the center of gravity, step and hip extension training, stepping up and down on stairs with the affected leg, standing up with hip extension and support of the leg, lateral walking, and in situ walking...

Patients with glioma whose tumors carry a mutation in isocitrate dehydrogenase 1 (IDH1R132H ) are younger at diagnosis and live longer. IDH1 mutations co-occur with other molecular lesions, such as 1p/19q codeletion, inactivating mutations in the tumor suppressor protein 53 (TP53 ) gene, and loss-of-function mutations in alpha thalassemia/mental retardation syndrome X-linked gene ( ATRX ). All adult low-grade gliomas (LGGs) harboring ATRX loss also express the IDH1R132H mutation. The current molecular classification of LGGs is based, partly, on the distribution of these mutations...

BACKGROUND: Chronic ankle instability (CAI) is a common disease following ankle sprain and appears balance and gait problems, pain, and fatigue. This study aimed to examine the effect of therapeutic exercise performed on sea sand on pain, fatigue, and balance ability in patients with CAI. METHODS: This study was designed as a randomized controlled trial. Subjects with a Cumberland Ankle Instability Tool (CAIT) score of less than 27 were selected. 22 subjects were randomly assigned to the sea sand (SS) group (n=11) or the self-management (SM) group (n=11)...

Context: Patients with diabetes mellitus are at increased risk for bone fragility fracture secondary to multiple mechanisms. Hyperglycemia can induce true dilutional hyponatremia. Hyponatremia is associated with gait instability, osteoporosis, and increased falls and bone fractures, and studies suggest that compromised bone quality with hyponatremia may be independent of plasma osmolality. We performed a case-control study of patients with diabetes mellitus matched by median glycated hemoglobin (HbA1c) to assess whether hyponatremia was associated with increased risk of osteoporosis and/or fragility fracture...

BACKGROUND: Gait instability is common in adults with neurological disorders and the modified Dynamic Gait Index (mDGI) was recently introduced to assess dynamic balance. However, instrumental assessment is needed to provide quantitative measures. OBJECTIVE: to develop and validate an instrumented version of the mDGI. DESIGN: cross sectional study. SETTING: clinical setting PARTICIPANTS: 30 adults with neurological disorders (10 with multiple sclerosis, 10 with Parkinson disease and 10 with stroke) and 20 healthy volunteers...

Gait variability is often associated with reduced coordination and increased instability during walking. Especially for patients with musculoskeletal conditions, variability in gait might be associated with the level of daily activity. Therefore, this study examines kinematic variability during walking and the association with daily activity in patients with transfemoral amputation. Therefore, 15 transfemoral amputees, using the C-leg prosthesis of Otto Bock, between 18 and 65 years were recruited during their hospital stay...

Background: Differentiating idiopathic Parkinson's disease (IPD) from atypical Parkinsonian disorders (APD) is challenging, especially in early disease stages. Postural instability and gait difficulty (PIGD) are substantial motor impairments of IPD and APD. Clinical evidence implies that patients with APD have larger PIGD impairment than IPD patients. Sensor-based gait analysis as instrumented bedside test revealed more gait deficits in APD compared to IPD. However, the diagnostic value of instrumented bedside tests compared to clinical assessments in differentiating APD from IPD patients have not been evaluated so far...

OBJECTIVE: Postural instability and gait difficulties (PIGD) represent debilitating disturbances in Parkinson's disease (PD). Prior acetylcholinesterase PET imaging studies implicate cholinergic changes as significant contributors to PIGD features. These studies were limited in quantification of striatal cholinergic synapse integrity. Vesicular acetylcholine transporter (VAChT) PET ligands are better suited for evaluation of high binding areas. We examined associations between regional VAChT expression and freezing of gait (FoG) and falls...

BACKGROUND: The prevalence and duration of NMS in prodromal PD has not been extensively studied. The aim of this study was to determine the prevalence and duration of prodromal NMS (pNMS) in a cohort of recently diagnosed PD patients. METHODS: We evaluated the prevalence and duration of prodromal NMS in early PD patients (n= 154). NMS were screened for using the Nonmotor Symptom Questionnaire (NMS Quest). We subtracted the duration of the presence of each individual NMS reported from the duration of earliest motor symptom...

OBJECTIVES: A high level of parathyroid hormone (PTH) was recently identified as a risk factor for falling. As balance instability is one of the major risk factors for falls, we aimed to investigate whether high PTH concentrations are associated with poor balance in older persons. STUDY DESIGN: Cross-sectional study with 127 community-dwelling older adults (75% female), aged 65-96 years, at the Falls and Fracture Clinic, Western Health-Sunshine Hospital, Melbourne, Australia...

Anterior instability after total hip arthroplasty (THA) has been described in patients with thoracolumbar kyphotic deformity. Although compensatory posterior pelvic tilt with subsequent increased functional anteversion has been described as the mechanism, there is a paucity of in-vivo data. The purpose of our study was to compare pelvic tilt, anteversion, inclination, and position of head-cup contact points in patients with lumbar degenerative disc disease (DDD) and a matched patient cohort without DDD. A total of 50 THA, 18 hips with lumbar DDD and 32 hips without DDD, underwent CT imaging for 3D hip reconstruction...

Parkinson's disease (PD) is a common neurodegenerative disorder that affects human's quality of life, especially leading to locomotor deficits such as postural instability and gait disturbances. Gait signal is one of the best features to characterize and detect movement disorders caused by a malfunction in parts of the brain and nervous system of the patients with PD. Various classification approaches using spatiotemporal gait variables have been presented earlier to classify Parkinson's gait. In this study we propose a novel method for gait pattern classification between patients with PD and healthy controls, based upon phase space reconstruction (PSR), empirical mode decomposition (EMD) and neural networks...

OBJECTIVE: There is no scale for rating the severity of autoimmune encephalitis (AE). In this study, we aimed to develop a novel scale for rating severity in patients with diverse AE syndromes and to verify the reliability and validity of the developed scale. METHODS: The key items were generated by a panel of experts and selected according to content validity ratios. The developed scale was initially applied to 50 patients with AE (development cohort) to evaluate its acceptability, reproducibility, internal consistency, and construct validity...

INTRODUCTION: Cancer frequently spreads to bone, causing cancer-induced bone pain (CIBP) which affects quality of life. The best treatment is radiotherapy (XRT), but response is variable. The aim of this systematic review was to identify factors that predict analgesic response. MATERIALS AND METHODS: Using PRISMA guidelines, Medline (1946-2018), Embase Classic + Embase (1947-2018) and Cochrane (setup-2018) databases were searched. Eligible studies examined adult patients receiving external beam XRT for CIBP with clinical marker and/or biomarkers evaluated...

A series of clinical research projects conducted over the past 40 years, all of which were informed by clinical observation or discussions with people with diabetes and staff colleagues are described in this review. A study of necrobiosis lipoidica iabeticorum confirmed that this rare skin complication occurs predominantly in young women with Type 1 diabetes and other microvascular complications. Biopsies of necrobiotic lesions showed destruction of superficial nerve fibres by inflammatory tissue, which likely causes the sensory loss in lesions that is pathognomonic of the condition...

Different clinical subtypes of Parkinson's disease (PD) have long been recognized. Recent studies have focused on two PD subtypes: Postural Instability and Gait Difficulty (PIGD) and Tremor Dominant (TD). PIGD patients have greater difficulties in postural control in relation to TD. However, knowledge about the differences in reactive adjustment mechanisms following a perturbation in TD and PIGD is limited. This study aimed to compare reactive postural adjustments under unexpected external perturbation in TD, PIGD, and control group (CG) subjects...
