We investigate the differential diagnostic value of tremor analysis of EMG on Parkinson's disease (PD), essential tremor (ET), and enhanced physiological tremor (EPT). Clinical data from 25 patients with PD, 20 patients with ET, and 20 patients with EPT were collected. The tremor frequency and muscle contraction pattern of the resting, posture, and 500 g and 1000 g overload were recorded. The frequency of PD tremor was 4-6 Hz, and the frequency of ET was also in this range; the frequency of EPT is 6-12 hz having some overlap with PD...

Essential tremor (ET) is among the most common neurological movement disorders that causes postural or action tremors, with an estimated prevalence nationwide of less than 3% of the population. The incidence of ET increases with age but often affects younger adults and has a familial trait association. Depending on disease progression, ET can cause significant limitations for individuals, in many cases, significantly limiting their ability to perform activities of daily living and occupational responsibilities...

The University of Québec in Montréal has agreements with trade unions providing access to university resources. Researchers involved in this program worked in partnership with union women's and health and safety committees for more than twenty years. Not all studies succeeded in improving women's working conditions. One joint project involved observational studies of tasks done by health-care workers, complemented by interviews and questionnaires. We found that task assignments, movements, postures, and work-related musculoskeletal disorders varied by gender/sex and made recommendations for change...

Osteoporosis, defined by BMD at the hip or lumbar spine that is less than or equal to 2.5 standard deviations below the mean BMD of a young-adult reference population, is the most common bone disease in humans affecting both sexes and all races. It's a silent killer affecting the quality of life due to fractures and postural changes. In osteoporosis there is an imbalance between bone formation and bone resorption in favor of latter. Preventive measures and treatments are available to combat this evil. Counseling is the integral part of prevention as well as treatment of osteoporosis...

Autism is a psychiatric disorder of unknown aetiology. In this article, the literature on genetic, neurological, psychological, relational and cultural causes of autism is reviewed, beginning with the 2014 review of Crittenden, Dallos, Landini et al. (pp. 64-70) up to and including recent publications in 2017. Some of the findings were unexpected; others led to new questions. The unexpected findings were the minimal contribution of genes to autism, the extremely evident neurological differences, the interpersonal quality of the psychological findings (that lacked evidence of parents' behaviour), the relational evidence that mothers' childhood trauma, perinatal stress and marital stress increased the risk of autism, and the reciprocal relation between funding for treatment of autism and diagnoses of autism...

INTRODUCTION: Although balance training is considered the most effective treatment for balance impairments in Parkinson's disease (PD), few studies have examined if learning for balance control remains intact with PD. This study aimed to determine if learning for automatic postural responses is preserved in people with PD. METHODS: Eleven participants with moderate PD (68±6.4years; H&Y: 2-3) on their usual medication maintained balance on a platform that oscillated forward and backward with variable amplitude and constant frequency...

Increased time-delay in the neuromuscular system caused by neurological disorders, concussions, or advancing age is an important factor contributing to balance loss (Chagdes et al., 2013, 2016a,b). We present the design and fabrication of an active balance board system that allows for a systematic study of stiffness and time-delay induced instabilities in standing posture. Although current commercial balance boards allow for variable stiffness, they do not allow for manipulation of time-delay. Having two controllable parameters can more accurately determine the cause of balance deficiencies, and allows us to induce instabilities even in healthy populations...

INTRODUCTION: In Essential Tremor (ET), tremor characteristics and the impairment caused by tremor may vary from task to task. A variability of tremor frequency between postural and kinetic tasks has been proposed in ET, suggesting either multiple central oscillating networks, or peripheral or proprioceptive feedback-mechanisms. This electrophysiological study aimed to assess tremor frequencies and amplitudes in tasks involving postural and kinetic tremor, and compare findings within and across tasks, to delineate physiological differences underlying individually affected manual tasks in ET...

Research on beneficial consequences of yoga focuses on the effects of yogic breathing and meditation. Less is known about the psychological effects of performing yoga postures. The present study investigated the effects of yoga poses on subjective sense of energy and self-esteem. The effects of yoga postures were compared to the effects of 'power poses,' which arguably increase the sense of power and self-confidence due to their association with interpersonal dominance (Carney et al., 2010). The study tested the novel prediction that yoga poses, which are not associated with interpersonal dominance but increase bodily energy, would increase the subjective feeling of energy and therefore increase self-esteem compared to 'high power' and 'low power' poses...

Successfully meeting a shared goal usually requires co-actors to adopt complementary roles. However, in many cases, who adopts what role is not explicitly predetermined, but instead emerges as a consequence of the differences in the individual abilities and constraints imposed upon each actor. Perhaps the most basic of roles are leader and follower. Here, we investigated the emergence of "leader-follower" dynamics in inter-personal coordination using a joint supra-postural task paradigm (Ramenzoni et al., 2011; Athreya et al...

Women experience orthostatic intolerance more than men, and experience faintness more in the early follicular (i.e. low hormone (LH)) compared to the luteal (i.e. high hormone (HH)) phase of the menstrual cycle. Men (n=13, age: 25.8±1.8) and women in the LH (day 2-5; placebo) and HH) (day 18-24; high dose) phases of the menstrual cycle with (OC; n=14, age: 22.0±0.8) or without oral contraceptives (NOC; n=12, age: 21.8±0.5) underwent the Valsalva maneuver and a supine-sit-stand protocol. Blood pressure, normalized stroke volume (SVi), cardiac output index (Qi), heart rate (HR), end-tidal carbon dioxide (ET-CO2), and middle cerebral artery blood velocity (MCA) were measured...

In the panorama of available musculoskeletal modeling software, AnyBody software is a commercial tool that provides a full body musculoskeletal model which is increasingly exploited by numerous researchers worldwide. In this regard, model validation becomes essential to guarantee the suitability of the model in representing the simulated system. When focusing on lumbar spine, the previous works aimed at validating the AnyBody model in computing the intervertebral loads held several limitations, and a comprehensive validation is to be considered as lacking...

Cervical dystonia (CD) is a neurological disorder with typical symptoms of involuntary and abnormal movements and postures of the head. CD-associated alterations of functional brain networks have not been well characterized. Previous studies of CD using resting-state functional MRI (rfMRI) are limited in two aspects: (i) the analyses were not directly focused on the functional brain network related to head movement and (ii) rfMRI measurements other than functional connectivity (FC) were not investigated. The present study examined alterations of FC in CD by capitalizing on newly identified brain regions supporting isometric head rotation (Prudente et al...

We have recently shown a diminishing of the Menopause Index in old-aged women who underwent special training directed at the enhancement of support afferentation by increasing the plantar forefoot sensitivity (Bazanova et al., 2015). Based on these results we hypothesized, that purposeful training of support afferentation through stimulation of plantar graviceptors by Aikido practice will decrease excessive postural and psychoemotional tension not only in rest condition, but during cognitive and manual task performance too...

BACKGROUND: Action tremor is the hallmark feature of essential tremor (ET). While the tremor typically is mildly asymmetric, in some patients, it is markedly asymmetric. There are few data on factors that influence this asymmetry. ET is also a highly familial disease. Whether the tremor asymmetry profile (i.e., differential expression of tremor in each arm in a given patient) is similar across family members is not known. The alternative possibility is that this feature is not heritable...

OBJECTIVE: To investigate the relationship between the morphological patency of the eustachian tube (ET) and sound transmission via the ET. STUDY DESIGN: Retrospective chart review and model experiment. SETTING: Tertiary referral center. SUBJECTS: A total of 56 ears of 28 patients (9 men and 19 women, aged from 12 to 82 yr, mean 40.4 ± 21.5 yr) who underwent sonotubometric measurement using postural change as well as computed tomography (CT) of the ET in the sitting position, including 26 ears with definite patulous ET, 9 ears with possible patulous ET, and 21 ears without patulous ET...

Rapid and reflexive responses to threats are present across phylogeny. The neural circuitry mediating reflexive defense reactions has been well-characterized in a variety of species, for example, in rodents and cats, the detection of and species-typical response to threats is mediated by a network of structures including the midbrain tectum (deep and intermediate layers of the superior colliculus [DLSC]), periaqueductal gray (PAG), and forebrain structures such as the amygdala and hypothalamus. However, relatively little is known about the functional architecture of defense circuitry in primates...

In humans, vertical posture acquisition caused several changes in bones and muscles which can be assumed as verticalization. Pelvis, femur, and vertebral column gain an extension position which decreases muscular work by paravertebral muscles in the latter. It's widely known that six different morphological categories exist; each category differs from the others by pelvic parameters and vertebral column curvatures. Both values depend on the Pelvic Incidence, calculated as the angle between the axes passing through the rotation centre of the two femur heads and the vertical axis passing through the superior plate of the sacrum...
