Body schema

Ana Deligiannis
This article explores how the body and imagination operate as pathways of knowledge through the use of Movement as Active Imagination in clinical practice. This method activates the transcendent function, thus encouraging new therapeutic responses. A philosophical perspective (Spinoza, Nietzsche, Merleau-Ponty) and some concepts from neuroscience (embodied cognition, somatic markers, image schema, mirror neurons, neuronal plasticity) will accompany us throughout this work, illustrated with a clinical vignette...

Our body is both, the object experiencing the world and the subject of our self- experience. As an object, the body provides sensory information via the bodily surface, which is processed and integrated into a coherent representation of the body, the body schema. This representation is considered to form a crucial structure underlying bodily self-identification. The process of integrating multimodal information into a coherent body representation has received extensive research interest with the aim to further clarify its neuronal correlates and functioning in health and disease...

Physiotherapists are well placed to help people adjust and engage meaningfully with the world following major weight loss. Recent research indicates that the body size a patient has lived with for years can continue to affect movement and perception even after largescale weight loss. This article explores this discrepancy in depth from the perspective of phenomenology and space perception and through the concepts of body image, body schema, and affordances. It draws on an empirical example in which a nautical engineer described his lived experience of returning to work following bariatric surgery and the discrepancies he experienced while adjusting to his new situation, particularly when moving his smaller body around the ship's engine room, previously inaccessible to him...

INTRODUCTION: Dysphagia and undernourishment are common in cerebrovascular accident (stroke) patients in developed countries. Despite the dietary transition, there is little information available in Africa on this topic. This study aims to assess the prevalence of undernourishment and dysphagia in stroke patients in two Burkina Faso teaching hospitals at a starting point (D0), on the eighth day, and on the 14th (D14) and to specify factors related to undernourishment at day 14. METHODOLOGY: The nutritional state of the patients was assessed using body mass index, triceps skinfold thickness, and mid-upper arm circumference...

BACKGROUND: The available antibiotic decision-making systems were developed from a physician's perspective. However, because infectious diseases are common, many patients desire access to knowledge via a search engine. Although the use of antibiotics should, in principle, be subject to a doctor's advice, many patients take them without authorization, and some people cannot easily or rapidly consult a doctor. In such cases, a reliable antibiotic prescription support system is needed. METHODS AND RESULTS: This study describes the construction and optimization of the sensitivity and specificity of a decision support system named IDDAP, which is based on ontologies for infectious disease diagnosis and antibiotic therapy...

OBJECTIVE: Many un-partnered women report difficulty in forming romantic relationships after breast cancer, characterized by high dating-related anxiety and low perceived interpersonal competence. This study examined the relationship between poor body image (appearance investment and body dissatisfaction) and self-compassion, and women's ability to form romantic relationships post-breast cancer. METHODS: Women (N=152) diagnosed with breast cancer, who were either un-partnered and expressed interest in romantic dating, or who had commenced a relationship post-diagnosis, completed an online survey...

OBJECTIVE: Musculoskeletal disorders are associated with altered sensory, proprioceptive and cognitive processes. Sensory processes affect the internal cortical representation of the body in space, the body schema, which in turn influences motor control. The purpose of this study was to determine if participants with wrist/hand disorders had impaired performance on a task associated with the body schema, the Left/Right Judgement Task (LRJT) and secondly how LRJT performance, motor performance, disability, pain and related aspects are associated...

To evaluate the detection rate of bone metastases obtained with the PSMA targeting tracer 99mTc-MIP-1427 as opposed to the conventional bone scan with 99mTc-MDP in a collective of advanced stage patients with known osseous metastasized prostate cancer. Methods: 21 Patients with known metastatic disease were staged with both, conventional bone scan and PSMA-ligand scintigraphy, within a time-frame of <10 days. Imaging included planar whole-body scans and SPECT or SPECT/CT with two bed positions 3 h after injection of either 500-750 MBq 99mTc-MIP-1427 or 600-750 MBq 99mTc-MDP...

INTRODUCTION: Childhood sexual abuse (CSA) has been identified as a potent risk factor for sexual dysfunction. Certain characteristics of the abuse experience, such as repeated abuse, appear to affect the risk of developing sexual dysfunction. Despite the robust findings that CSA can be detrimental to sexual function, there is little consensus on the exact mechanisms that lead to these difficulties. AIM: To summarize the most up-to-date research on the relation between CSA and women's sexual function...

Objective: Although research on muscle dysmorphia (MD), a body dysmorphic disorder subtype, has recently increased, the causes and mechanisms underlying this disorder remain unclear. Results from studies examining disorders associated with body image suggest the involvement of self-schema in biasing attention toward specific body information. The present study examined whether individuals at higher risk of MD also display attentional biases toward specific types of body images. Methods: The validated Chinese version of the Muscle Appearance Satisfaction Scale was used to distinguish men at higher and lower risk of MD...

Purpose This study aimed to test a group psychosocial intervention focused on improving disturbances of body image (BI), sexual functioning, and quality of life in breast cancer (BC) survivors. Methods A prospective, randomized controlled trial was conducted to assess the efficacy of an 8-week group intervention in women after BC treatment. The manual-based intervention combined two powerful ingredients: expressive guided-imagery exercises integrated within a model of group-therapy principles. The intervention facilitates exploration of identity, the development of new self-schemas, and personal growth...

BACKGROUND: "Alice in Wonderland" syndrome (AIWS) is a rare neurological abnormality characterized by distortions of visual perceptions, body schema and experience of time. AIWS has been reported in patients with various infections such as infectious mononucleosis, H1N1 influenza, Cytomegalovirus encephalitis, and typhoid encephalopathy. However, AIWS occurring in a patient with severe malaria is less familiar and could pose serious primary care challenges in a low-income context. CASE PRESENTATION: A 9-year-old male of black African ethnicity was brought by his parents to our primary care hospital because for 2 days he had been experiencing intermittent sudden perceptions of his parents' heads and objects around him either "shrinking" or "expanding"...

This study focuses on how the body schema develops during the first months of life, by investigating infants' motor responses to localized vibrotactile stimulation on their limbs. Vibrotactile stimulation was provided by small buzzers that were attached to the infants' four limbs one at a time. Four age groups were compared cross-sectionally (3-, 4-, 5-, and 6-month-olds). We show that before they actually reach for the buzzer, which, according to previous studies, occurs around 7-8 months of age, infants demonstrate emerging knowledge about their body's configuration by producing specific movement patterns associated with the stimulated body area...

Background: The well-known rubber hand paradigm induces an illusion by having participants feel the touch applied to a fake hand. In parallel, the kinesthetic mirror illusion elicits illusions of movement by moving the reflection of a participant's arm. Experimental manipulation of sensory inputs leads to emergence of these multisensory illusions. There are strong conceptual similarities between these two illusions, suggesting that they rely on the same neurophysiological mechanisms, but this relationship has never been investigated...

OBJECTIVES: To determine whether hand left/right judgements, tactile acuity, and body perception are impaired in people with hand OA. To examine the relationships between left right judgements, tactile acuity and hand pain. To explore the relationships between sensorimotor measures (left/right judgements and tactile acuity) and measures of hand function in people with hand OA. METHODS: Twenty patients with symptomatic hand OA and 19 healthy pain-free controls undertook a hand left/right judgment task, a control left/right judgement task, two-point discrimination (TPD) threshold testing (assessing tactile acuity), a neglect-like symptoms questionnaire (assessing body perception) and several established measures of hand function...

Advances in structural and functional neuroimaging offer new ways to conceptualize chronic pain disorders and to prevent, diagnose, and treat chronic pain. Advances in pain science, though, do not entail changes in the concepts of chronic pain in law and culture. Authoritative legal and cultural conceptions of chronic pain continue to promote abstruse theories, characterizing these disorders as arising out of everything from a person's unmet need for love to resistance to "patriarchy." These constructs have consequences, impeding treatment and affecting whether individuals with chronic pain can obtain legal redress...

BACKGROUND: Body representation disturbances in body schema (i.e. unconscious sensorimotor body representations for action) have been frequently reported in eating disorders. Recently, it has been proposed that body schema relies on adequate functioning of the motor system, which is strongly implicated in discriminating between one's own and someone else's body. The present study aimed to investigate the motor-based bodily self in eating disorders and controls, in order to examine the role of the motor system in body representation disturbances at the body schema level...

BACKGROUND: Movements may be generated consistent with imagining one's own body transformed or "disembodied" to a new position. Based on this concept we hypothesized that patients with objective balance deficits (obj-BD) would have altered neural transformation processes executing own body transformation (OBT) with functional consequences on balance control. Also we examined whether feeling unstable due to dizziness only (DO), without an obj-BD, also lead to an impaired OBT. METHODS: 32 patients with chronic dizziness were tested: 16 patients with obj-BD as determined by balance control during a sequence of stance and gait tasks, 16 patients with dizziness only (DO)...

In studying human perception and performance researchers must understand how the body schema is modified to accurately represent one's capabilities when tools are used, as humans use tools that alter their capabilities frequently. The present work tested the idea that calibration is responsible for modifying an embodied action schema during tool use. We investigated calibration in the context of manual activity in near space through a behavioral measure. Participants made blind reaches to various visual distances in pre- and post-test phases using a short tool that did not extend their reach...
