This course will focus on the theory, administration, scoring, and interpretation of the Structured Observations of Sensory-Motor Integration (SOSI-M) and the Comprehensive Observations of Proprioception (COP-R) and their relationship to other assessment tools and observations. The SOSI-M is an assessment for children between 5 and 14 years of age based on Dr. Ayres’ clinical observations, standardized scores in a national sample (USA) and numerous pilot studies in more than 5 countries. Through the use of videotaped cases, hand-on experiences and didactic presentations, this hybrid workshop will help participants identify motor planning and postural control issues related to vestibular and proprioceptive functions impacting performance and participation. Thus, targeting interventions with children with developmental disabilities e.g., Autism Spectrum Disorders, Developmental Coordination Disorders and Sensory Processing Disorders The SOSI-M includes 14 observations that allow therapists to expand their field of action in the diagnosis of sensory-motor problems in children and preadolescents. The COP-R is an observation-based instrument that includes the analysis of 18 items and is one of the first instruments to measure proprioception in the clinical setting. Both instruments allow therapists to obtain and report additional results in the areas of postural control, motor planning, and vestibular and proprioceptive processing. In this course the authors will guide participants in the administration, scoring and clinical interpretation of the results obtained with both instruments. This course must be passed with 75% on a multiple-choice exam.
