In everyday life the brain must adapt to variable situations that may require a mixture of approaches including anticipatory synergy formation, through an internal body schema, and different control strategies. Unstable tasks are particularly challenging because deteriorate the predictive power of internal models and further enhance the instability potential of delayed sensory feedback. We explore this issue by means of three simulation studies: A) The hybrid control of a double inverted pendulum model, B) The bimanual stabilization of a saddle-like instability, C) Whole-body focal-postural dynamics...

Patients with lesions of the left posterior parietal cortex commonly fail in identifying their fingers, a condition known as finger agnosia, yet are relatively unimpaired in sensation and skilled action. Such dissociations have traditionally been interpreted as evidence that structural body representations (BSR), such as the body structural description, are distinct from sensorimotor representations, such as the body schema. We investigated whether performance on tasks commonly used to assess finger agnosia is modulated by changes in hand posture...

OBJECTIVE: To determine how and under which conditions psoriasis is related to the psychological impairments, in particular, to social anxiety and depression, the current study tested the interplay of selected factors such as gender, age of onset of psoriasis, cognitive and affective elements of body image, experiences of stigmatization, and patients' subjective perceptions of severity of the disease. METHODS: Adult psoriasis patients (N=193) completed the Appearance Schemas Inventory-Revised, the Stigmatization Scale, the Body Emotions Scale, the Beck Depression Inventory, and the Social Anxiety Questionnaire...

Ward climate is a key element within psychiatric settings, associated with positive clinical outcomes. The Essen Climate Evaluation Schema (EssenCES) is a ward climate measure, which is validated for use within UK forensic settings. It has been studied within neurodevelopmental psychiatric inpatient settings with mixed findings on its appropriateness, and there is a dearth of EssenCES research which has been conducted within an adolescent psychiatric inpatient setting. The present study piloted the EssenCES within an inpatient psychiatric neurodevelopmental setting for adolescents in the East of England, in order to explore its usefulness within this setting and to provide preliminary normative data for a child and adolescent mental health services inpatient learning disability population...

BACKGROUND: Disruption of cortically-held working body schema has been associated with a variety of pain conditions. A motor imagery technique - the left right judgement task (LRJT) - has been used as an indirect assessment of the integrity of the working body schema. To date there is no LRJT specifically designed to investigate the body schema of persons with shoulder pain. OBJECTIVES: To develop a shoulder specific LRJT and assess its validity and reliability...

Here we argue functional neuroanatomy for posture-gait control. Multi-sensory information such as somatosensory, visual and vestibular sensation act on various areas of the brain so that adaptable posture-gait control can be achieved. Automatic process of gait, which is steady-state stepping movements associating with postural reflexes including headeye coordination accompanied by appropriate alignment of body segments and optimal level of postural muscle tone, is mediated by the descending pathways from the brainstem to the spinal cord...

Robot-assisted rehabilitation of stroke survivors mainly focuses on the impaired side of the body while the role of the unimpaired side in the recovery after stroke is still controversial. The goal of this study is to investigate the influence on sitting balance and paretic arm functions of a training protocol based on movements of the unimpaired arm. Sixteen chronic stroke survivors underwent nineteen training sessions, in which they performed active movements with the unimpaired arm supported by a passive exoskeleton...

The paradigm of simultaneous and proportional myocontrol of hand prostheses is gaining momentum in the rehabilitation robotics community. As opposed to the traditional surface electromyography classification schema, in simultaneous and proportional control the desired force/torque at each degree of freedom of the hand/wrist is predicted in real-time, giving to the individual a more natural experience, reducing the cognitive effort and improving his dexterity in daily-life activities. In this study we apply such an approach in a realistic manipulation scenario, using ten non-linear incremental regression machines to predict the desired torques for each motor of two robotic hands...

Stroke can lead to motor impairments that can affect the body structure and restraint mobility. We hypothesize that brain lesions and their motor sequelae can distort the body schema, a sensorimotor map of body parts and elements in the peripersonal space through which human beings embody the reachable space and ready the body for forthcoming movements. Two main constructs have been identified in the embodiment mechanism: body-ownership, the sense that the body that one inhabits is his/her own, and agency, the sense that one can move and control his/her body...

Individuals with mirror-touch synesthesia (MTS) report feeling touch on their own body when seeing someone else being touched. We examined how the body schema - an on-line representation of body position in space - is involved in mapping touch from a viewed body to one's own body. We showed 45 mirror-touch synesthetes videos of a hand being touched, varying the location of the viewed touch by hand (left, right), skin surface (palmar, dorsal) and finger (index, ring). Participant hand posture was either congruent or incongruent with the posture of the viewed hand...

Proprioceptive signals originating from skeletal muscles and joints contribute to the formation of both the human body schema and the body image. In this chapter, we introduce various types of bodily illusions that are elicited by proprioceptive inputs, and we discuss distinct functions implemented by different parietal cortices. First, we illustrate the primary importance of the motor network in the processing of proprioceptive (kinesthetic) signals originating from muscle spindles. Next, we argue that the right inferior parietal cortex, in concert with the inferior frontal cortex (both regions connected by the inferior branch of the superior longitudinal fasciculus-SLF III), may be involved in the conscious experience of body image...

BACKGROUND: Preliminary studies suggest that both childhood experiences and coping behaviours may be linked to eating disorder symptoms. METHODS: In this study maladaptive schema coping modes were investigated as mediators in the relationship between perceived negative parenting and disordered eating. A total of 174 adults with eating and/or body image concerns completed questionnaires measuring parenting experiences, schema modes, and disordered eating behaviours...

REVIEW
Feras Oskan, Gerd Becker, Martin Bleif
The toxicity of stereotactic body radiation therapy in the central chest remains an unsettled issue. The collected data concerning the observed complications are poorly understood and are limited in their quantity and quality, thus hampering a precise delineation of treatment-specific toxicity. The majority of complications scored as toxicity grade 5, namely respiratory failure and fatal hemoptysis, are most likely related to multiple competing risks and occurred at different dose fractionation schemas, e...

Parkinson's disease (PD) presents as an illness which predominantly affects older men. However older men's lived experiences of PD, including how they are influenced by age and gender relations has seen little empirical study. Drawing on Watson's male body schema, this paper explores how men engage with masculinities and ageing in order to make sense and meaning from PD. Data is presented from 30 narrative and semi structured interviews with 15 men of various ages who were living with PD. Findings suggest that PD threatens a visceral embodiment located in the body's basic movements and intimate functions; a pragmatic embodiment expressed through men's everyday occupations and an experiential embodiment concerned with emotions and sensations felt within and through the body...

The purpose of this study was to perform a construct validity assessment of Kendzierski's exercise self-schema theory questionnaire using objective measures of health-related physical fitness. This study tested the hypothesis that individuals with an exercise self-schema would possess significantly greater physical fitness than those who did not across three domains of health-related physical fitness: Body composition, cardiovascular fitness, and upper-body muscular endurance. Undergraduate student participants from one private university on the west coast of the United States completed informed consent forms and the exercise self-schema questionnaire within a classroom setting or at an on-campus outside tabling session...

This study examined the relationship between psoriasis and depression, proposing a multiple mediation model to analyse the relationship. A total of 193 patients with psoriasis aged 20-67 years completed the Beck Depression Inventory, the Stigmatization Scale, the Appearance Schemas Inventory-Revised, and the Body Emotions Scale. The Body Surface Area index was used to assess severity of psoriasis. Serial multiple mediation analysis revealed that experiences of stigmatization, maladaptive beliefs about appearance and its salience to one's self-evaluation, and negative emotional attitudes towards the body, jointly, sequentially mediated the relationship between the presence of skin lesions of psoriasis and depressive symptoms...

OBJECTIVE: This article describes how maps were developed from the clinical modifications of the 9th and 10th revisions of the International Classification of Diseases (ICD) to the Abbreviated Injury Scale 2005 Update 2008 (AIS08). The development of the mapping methodology is described, with discussion of the major assumptions used in the process to map ICD codes to AIS severities. There were many intricacies to developing the maps, because the 2 coding systems, ICD and AIS, were developed for different purposes and contain unique classification structures to meet these purposes...

Calculating internal dose from therapeutic radionuclides currently relies on estimates made from multiple radiation exposure measurements, converted to absorbed dose in specific organs using the Medical Internal Radiation Dose (MIRD) schema. As an alternative biodosimetric approach, we utilized gene expression analysis of whole blood from patients receiving targeted radiotherapy. Collected blood from patients with relapsed or refractory neuroblastoma who received (131)I-labeled metaiodobenzylguanidine ((131)I-mIBG) at the University of California San Francisco (UCSF) was used to compare calculated internal dose with the modulation of chosen gene expression...
