Beat gestures, rhythmic hand movements that co-occur with speech, appear to be uniquely associated with the cerebellum in healthy individuals. This behavior may also have relevance for psychosis-risk youth, a group characterized by cerebellar dysfunction. This study examined beat gesture frequency and postural sway (a sensitive index of cerebellar functioning) in youth at ultrahigh risk (UHR) for psychosis. Results indicated that decreased beat gesture frequency, but not self-regulatory movement, is associated with elevated postural sway, suggesting that beat gestures may be an important biomarker in this critical population...

Sensorimotor training with a wide variety of available devices represents an important component in rehabilitation and prevention of different sports injuries and chronic diseases. The purpose of this study was to evaluate the effects of a sensorimotor training with a newly developed device, which consists of an instable platform moving on an air cushion, providing dynamic balance training by tilting and unanticipated stochastic translations on postural control. Seventy-two healthy young subjects were included in this prospective, randomized, controlled, and observer-blinded study...

Alternative exercise traditions (AETs) such as Pilates, yoga, Tai Chi Chuan, Qigong, and various forms of dance offer the potential to improve diverse outcomes among cancer survivors by reducing adverse symptoms and mood disorders, and by enhancing function. Additionally AETs have emerged as a potential means to address deficits in current disease-focused care delivery models which are marked by prevalent under-treatment of symptoms and physical impairments. Relative to therapeutic exercise in allopathic models, many AETs are comparatively affordable and accessible...

OBJECTIVES: The effects of mind-body exercises on individuals with chronic illnesses have attracted increasing attention. However, little effort had been made to systematically review the effects of these mind-body exercises on individuals with Parkinson's disease (PD). This review aimed to appraise the current evidence of the effects of mind-body exercises on the physiological and psychological outcomes for the PD population. DESIGN: Systematic review and meta-analysis of randomized controlled trials...

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)...

Typically, balance training has been used as an intervention paradigm either as static or as reactive balance training. Possible differences in functional outcomes between the two modalities have not been profoundly studied. The objective of the study was to investigate the specificity of neuromuscular adaptations in response to two balance intervention modalities within test and intervention paradigms containing characteristics of both profiles: classical sensorimotor training (SMT) referring to a static ledger pivoting around the ankle joint vs...

BACKGROUND/OBJECTIVES: Constipation is a condition that can result from intestinal deformation. Because humans have an upright posture, the effects of gravity can cause this shape deformation. Oligosaccharides are common prebiotics and their effects on bowel health are well known. However, studies of the physiological functionality of a product that contains both lactulose and galactooligosaccharides are insufficient. We investigated the constipation reduction effect of a dual-type oligosaccharide, Dual-Oligo, in loperamide-treated rats...

AIM: To study the process of recovery of postural function during stabilometric training with biofeedback (BFB) in patients with ischemic carotid stroke. MATERIAL AND METHODS: Forty-two patients underwent 10-day stabilometric training from the onset of stroke. Clinical and stabilometric parameters were assessed at 4 points: at baseline, after 5 sessions, after 10 sessions and after 3-4 months in the early recovery stage after discharge from the hospital. RESULTS: There was no correlation between the positive regress of neurologic symptoms and trends of stabilometry indicators...

BACKGROUND: Subacromial impingement is a common condition among overhead athletes. The cause of subacromial impingement can be multifactorial and often involves impaired rotator cuff function. CASE DESCRIPTION: The following cases outline the presentation, examination and intervention of two overhead athletes, a high school football quarterback and a collegiate swimmer, each presenting with signs and symptoms of subacromial impingement. The unique feature in each case was the manifestation of the cervical spine as the apparent source of rotator cuff weakness, which contributed to functional subacromial impingement although other overt signs of cervical or associated nerve root involvement were absent...

OBJECTIVE: To investigate the relation between orthostatic hypotension (OH) and posture-mediated cognitive impairment in Parkinson disease (PD) using a cross-sectional and within-group design. METHODS: Individuals without dementia with idiopathic PD included 18 with OH (PDOH) and 19 without OH; 18 control participants were also included. Neuropsychological tests were conducted in supine and upright-tilted positions. Blood pressure was assessed in each posture. RESULTS: The PD groups performed similarly while supine, demonstrating executive dysfunction in sustained attention and response inhibition, and reduced semantic fluency and verbal memory (encoding and retention)...

Human bipedal locomotion is characterized by a habitual heel-strike (HS) plantigrade gait, yet the significance of walking foot-posture is not well understood. To date, researchers have not fully investigated the costs of non-heel-strike (NHS) walking. Therefore, we examined walking speed, walk-to-run transition speed, estimated locomotor costs (lower limb muscle volume activated during walking), impact transient (rapid increase in ground force at touchdown) and effective limb length (ELL) in subjects (n=14) who walked at self-selected speeds using HS and NHS gaits...

Temporo-spatial observation of the leg could provide important information about the general condition of an animal, especially for those such as sheep and other free-ranging farm animals that can be difficult to access. Tri-axial accelerometers are capable of collecting vast amounts of data for locomotion and posture observations; however, interpretation and optimization of these data records remain a challenge. The aim of the present study was to introduce an optimized method for gait (walking, trotting and galloping) and posture (standing and lying) discrimination, using the acceleration values recorded by a tri-axial accelerometer mounted on the hind leg of sheep...

BACKGROUND: Ideomotor apraxia (IMA) is known to affect individuals with Alzheimer's disease (AD). Combined with impaired cognitive function, IMA can support evidence of probable AD. However, apraxia is a condition that is difficult to diagnose. The Postural Knowledge Test (PKT), developed by Mozaz et al, was designed to easily identify limb apraxia in multiple sclerosis yet demonstrated potential utility for AD. ILIAD is a pilot study to investigate correlation between the PKT and Mini-Mental State Examination (MMSE)...

Truncating ASXL3 mutations were first identified in 2013 by Bainbridge et al. as a cause of syndromic intellectual disability in four children with similar phenotypes using whole-exome sequencing. The clinical features - postulated by Bainbridge et al. to be overlapping with Bohring-Opitz syndrome - were developmental delay, severe feeding difficulties, failure to thrive and neurological abnormalities. This condition was included in OMIM as 'Bainbridge-Ropers syndrome' (BRPS, #615485). To date, a total of nine individuals with BRPS have been published in the literature in four reports (Bainbridge et al...

BACKGROUND/AIM: Consequences of an anterior cruciate ligament (ACL) injury include worse patient-reported outcomes (PROs) and a decrease in activity level. Muscle function can be improved by targeted exercise. Our aims were to investigate cross-sectional and longitudinal associations among lower extremity muscle function and PROs after ACL injury. METHODS: Fifty-four participants (15 women, mean 30 years) with ACL injury or reconstruction, from the Knee Anterior Cruciate Ligament, Nonsurgical versus Surgical Treatment (KANON) trial (ISRCTN84752559), were assessed with hop performance, muscle power and postural orientation 3 years (SD 0...

OBJECTIVE: The cardiovascular system maintains homeostasis through a series of adaptive responses to physiological requirements. However, little is known about the adaptation of fetal cardiac function to gravity, according to gestational age. In the present study, we aimed to evaluate the adaptive responses of cardiac function to postural changes, using Tei index measurements. METHODS: Fetal echocardiography and Doppler examination were performed on 114 women with vertex singleton pregnancies at 19 to 40 weeks' gestation...

Cervical dystonia (CD) is a neurological disorder characterized by abnormal movements and postures of the head. The brain regions responsible for these abnormal movements are not well understood, because most imaging techniques for assessing regional brain activity cannot be used when the head is moving. Recently, we mapped brain activation in healthy individuals using functional magnetic resonance imaging during isometric head rotation, when muscle contractions occur without actual head movements. In the current study, we used the same methods to explore the neural substrates for head movements in subjects with CD who had predominantly rotational abnormalities (torticollis)...

REVIEW
Thierry Paillard
This review addresses the possible structural and functional adaptations of the postural function to motor experience. Evidence suggests that postural performance and strategy evolve after training in inactive subjects. In trained subjects, postural adaptations could also occur, since elite athletes exhibit better postural performance than, and different postural strategy to sub-elite athletes. The postural adaptations induced are specific to the context in which the physical activity is practiced. They appear to be so specific that there would be no or only a very slight effect of transfer to non-experienced motor tasks (apart from in subjects presenting low initial levels of postural performance, such as aged subjects)...

BACKGROUND AND PURPOSE: Falls are the leading cause of disability, injury, hospital admission, and injury-related death among older adults. Balance limitations have consistently been identified as predictors of falls and increased fall risk. Field measures of balance are limited by issues of subjectivity, ceiling effects, and low sensitivity to change. The gold standard for measuring balance is the force plate; however, its field use is untenable due to high cost and lack of portability...
