  • FINNISH RIDING THERAPY Riding therapy is functional in its nature. It exposes the patient as a whole person to a total experience. This experience includes the entire body, its feelings, thoughts into a continuous sensory and motor experience. An experience shared by the rider, the horse and the total environment. A truly holistic experience.Monday, March 21, 2011

  • PERCEPTION Perception refers to the person’s ability to understand, or make meaning out of the sensory input received through the sensory organs (such as the eyes and ears). The perceptual process occurs through mechanisms in the brain that link the current sensory information with memories and past experiences with similar sensory information. Kandel, E., Schwartz, J. & Jessell, T.(2000)Monday, March 21, 2011
  • PERCEPTION STIMULUS SENSATION INTERPRETATION COMPREHENSIONMonday, March 21, 2011
  • PERCEPTION Perception depends on both learning and maturation. Babies are not given the perceptual world with all its categories at birth. They actively create it through they experiences, memories and cognitive processes. We have to learn how to see and hear with meaning. We develop our sensory processing skills and achieve the comprehension through interaction with the enviroment. Bogdashina 2003Monday, March 21, 2011
  • Human development is a blend of nature and nurture, genes and environment. There is no cognitive, perceptual, emotional, or motor skill that is not influenced by both of these factors. Brain development is "activity-dependent," meaning that the electrical activity in every circuit--sensory, motor, emotional, cognitive--shapes the way that circuit gets put together.Monday, March 21, 2011
  • Monday, March 21, 2011
  • NEURONS The brain is made of nerve cells or neurons, which are specialized to carry messages in our body. The human brain has about 100 milliard neurons.Monday, March 21, 2011
  • SYNAPSE Information from one neuron to another flows across a synapse. Every neuron has thousands of connections with other neurons. Every synapse is able for hundreds of operations.Monday, March 21, 2011

  • PROPRIOCEPTION GOLGI TENDON ORGAN MUSCLE SPINDELMonday, March 21, 2011
  • Sense organs start to work when something stimulates receptors. Once stimulated, the receptors send nerve impulses along sensory nerves.Monday, March 21, 2011
  • Most of the sensory information (except smell) passes through the thalamus and then to the opposite hemisphere of the cortex. The signals from each sensory organ are processed in specialized areas of the brain. When the information reach the cerebral cortex we become conscious of the stimuli and the brain tell us what the stimulus is.Monday, March 21, 2011
  • BODY SCHEMASMonday, March 21, 2011
  • BODY SCHEMAS • Body schemas are the internal representations of the anatomy and dynamics of the body in the brain. • They are built up by sensory information.Monday, March 21, 2011

  • SENSORY PROFILE ( Dunn 2001) • Sensory profile provides a standard method for measuring and reporting sensory processing abilities in everyday life. • It provides a tool for linking performance strengths and barriers with sensory processing patterns. • Each measure describes a persons response to various sensory experiences. • Caregivers complete the questionnaire.Monday, March 21, 2011
  • Monday, March 21, 2011
  • NEUROLOGICAL THRESHOLDS Refer to the amount of stimuli required for a neuron or neuron system to respond. When the nervous system responds really quickly to a sensory stimulus, there is a low threshold = hyper- responsive (or overresponsive) When the nervous system responds more slowly than expected, there is a high threshold = hypo-responsive (or under responsive) for responding. Dunn 2003Monday, March 21, 2011
  • The Effects of Equine Assisted Activities on the Social Functioning of Children with Autism Margaret M. Bass, Ph.D. Maria Llabre, Ph.D. • The Social Responsiveness Scale (SRS) and Sensory Profile (SP) were completed by teachers and parents to assess social functioning at three times: pre-and-post intervention and a two month follow-up. • The means between the treatment and control groups at post-test indicated significant group differences on the following SP scales: Sensory seeking, emotionally reactive, inattention/distractibility, and sensory sensitivity.Monday, March 21, 2011
  • SENSORY INFORMATION Sensory information is critical not only for the development of the central nervous system but also for the adaptation to the surrounding world and for moving and learning. The ability to relate sensory input to motor output forms the basis of posture control development. Hadders-Algra 2005Monday, March 21, 2011
  • SENSORY INPUT MOTOR OUTPUTMonday, March 21, 2011
  • Normal development is coded by genes until 4 months of age. Feedback of child’s own moving is important to the normal development. This selection process creates favored muscle synergies or functional strategies for performing movements associated with desired actions from among the many combinations of movements that could be effective. Hadders-Algra 2002Monday, March 21, 2011
  • NEURAL CONTROL OF HUMAN MOTOR DEVELOPMENT (H.Forsberg ) The development of postural muscle activation patterns in sitting infants.Monday, March 21, 2011
  • CENTRAL PATTERN GENERATORS (CPGs) Locomotion and other rhythmic motor behaviours are based on the activity of spinal functional networks generating the rhythm and shaping the pattern of burts of motoneurons. These networks are called central pattern generators, CPGs, which are capable producing coordinated movements which require afferent and supraspinal input. (Grillner, 1986, Forsberg and Dietz 1997)Monday, March 21, 2011
  • CENTRAL PATTERN GENERATORS The evidence for existence of CPGs comes from newborns; infant stepping is initiated or triggered by peripheral stimuli. (Zehr and Duysens 2004) Another evidence is in persons with paraplegia; locomotor EMG activity and movements can be both elicited and trained. (Dietz 1997) CPGs are active controllers of human rhythmic movements. Monday, March 21, 2011
  • Monday, March 21, 2011
  • SENSORY FEEDBACK • The fine regulation of rhythmic human movements typified by locomotion can be understood as the sublime interaction of a triparte system consisting of supraspinal input, spinal central pattern generating circuits (CPG), and sensory feedback (Zehr 2004) • Sensory feedback is an integral part of the over all and is critical in modifying CPG-generated motor programs in online adaptations to environment (MacKay-Lyons 2002, Dietz 2003) • The control of locomotion involves the use of afferent information from variety of sources in the visual, vestibular, tactile and proprioceptive systems (Dietz 2003)Monday, March 21, 2011
  • SENSORY INPUT It is well documented that rhythmic and repetitive proprioceptive and tactile input indicates changes in the anatomy and function of the sensomotor cortex. (Kaas JH et al,1999) Also passive repetitive proprioceptive stimulation change the representation of the used body part. Lewis GN 2004Monday, March 21, 2011
  • To be effective, the sensory information must be meaningful for the person; the activity must produce pleasure or lead to the wanted goal. If the brain of a person cannot give meaning for the sensory information produced by the means of an activity, the brain slowly ignores theMonday, March 21, 2011
  • Movement, in it´s effectiveness, can take place of any other modality, but no therapeutic modality in the world can replace the effect of movement. Clemens Josef Tissot 1750-1826Monday, March 21, 2011
  • As research techniques and technology become more sophisticated, scientists and practioners gain knowledge and achieve a better understanding of the complexity of the CNS.Monday, March 21, 2011
  • University of Rostock, Germany 2011 Basic neurobiological and psychological mechanisms underlying therapeutic effects of Equine Assisted Activities (EAA/T) The activation of the oxytocin system is indirectly operationalized via measuring a set of indicators capturing the well investigated effects of oxytocin on stress (cortisol, heart rate), trust, and social behavior.Monday, March 21, 2011
  • Vanderbuilt Brain Istitute, Multisensory Research Laboratory, USA 2011 Altered Multisensory Processes in Autism Spectrum Disorder A better characterization of some of the fundamental aspects of (multi)sensory processing will represent an important step forward in our understanding of ASD, and should shed important insights into the neural substrates of this complex developmental disorder, as well as inform the design of more effective interventional strategies. Both sensory and multisensory processes are impacted in Autism.Monday, March 21, 2011
  • PLASTICITY Plasticity is the lifelong ability of the brain to reorganize neural pathways on the basis of new experiences. Learning and memory are classical examples of neuroplasticity. Monday, March 21, 2011
  • MULTISENSORY INTEGRATION = MULTIMODAL INTEGRATION MULTISENSORY PROCESSING A STUDY HOW DIFFERENT SENSORY MODALITIES ARE INTEGRATED BY THE NERVOUS SYSTEM AND HOW HOW THEY INTERACT WITH ONE ANOTHER AND ALTER EACH OTHERʼS PROCESSING.Monday, March 21, 2011
  • www.imrf.info • The International Multisensory Research Forum (IMRF) facilitates communication between scientists who work with sensory systems in which more than one sense modality plays a role. We seek to include any and all sense modalities, species, scientific disciplines, and perspectives (anatomical, cognitive, behavioral, computational, developmental, engineering, physiological, and others).Monday, March 21, 2011

  • Multisensory enviroment MS is an interactive environment that generates real time stimuli of different senses. SNOEZELEN Snoezelen is a non-directive therapy and can be staged to provide a multi-sensory experience or single sensory focus, simply by adapting the lighting, atmosphere, sounds, and textures to the specific needs of the client at the time of use.Monday, March 21, 2011
  • Multisensoring marketing Multisensory marketing and sensory branding is based on the idea that we are most likely to form, retain and revisit memory when all five senses are engaged. Joshua G. Giordimaina 2008Monday, March 21, 2011

  • ”Sometimes when other kids spoke to me I would sc arcely hear, then sometimes they sounded like bullets.” ”I did not see whole. I saw hair, i saw eyes, nose, mouth, chin…not face” ” Together, the sharp sounds and the bright lights were more than enough to oveload my sense. My head would feel tight, my stomach would churn, and my pulse would run my heart ragged until i found a safety zone.”Monday, March 21, 2011

  • Spatial, temporal and physical characteristics of the sensory stimuli that are combined critically determine how they are synthesized. Thus, multisensory stimuli that are in close physical proximity, that occur at or near the same moment in time, that are weakly effective on their own, and that are contextually similar result in enhanced neural activity Monday, March 21, 2011
  • Monday, March 21, 2011
  • Poor balance is often associated with neurological disorders and behind balance problems there are often impairments in sensory systems and body awareness. Deficits in sensory integration processes are often suspected as an underlying source of balance disorders in individuals who have sustained brain changes due to disease, trauma or aging.Monday, March 21, 2011
