* February 8, 2019: "Meeting the Challenge of Developmental Coordination Disorder (DCD) with Associated Medical and Educational Diagnoses", Integrative Education Symposium, Continuing Education and Conference Center, University of Minnesota, St. Paul Campus, 1890 Buford Avenue, Saint Paul, MN

This session describes practical approaches for providing services to children with Developmental Coordination Disorder, which is recognized by the Diagnostic and Statistical Manual of Mental Disorders - Fifth edition(DSM-5). Content includes: Theoretical foundations for impairments in skilled motor movements, implications for activities of daily living (ADLs), and strategies for individualization of therapeutic activities. Associated co-concurrent conditions such as attention deficit/hyperactivity disorder (ADHD), autism, learning disabilities (LD), Sensory Processing Disorders (SPD), and emotional-behavioral problems will be discussed in terms of commonalities with DCD.


We produce and distribute a variety of materials for professionals working with children who have developmental and multiple disabilities. The company was founded in 1989 by Rhoda P. Erhardt, MS, OTR/L, FAOTA, an occupational therapist specializing in pediatrics for more than 45 years. Mrs. Erhardt received her B.S. in occupational therapy from the University of Illinois, M.S. in child development from North Dakota State University, and pediatric NeuroDevelopmental Treatment (NDT) training in London, England. Her curriculum vitae includes education, work experience, honors, professional affiliations, consultation contracts, and publications

Currently in private practice in the Minneapolis/St.Paul area, she has provided evaluation and consultation services to families, health agencies, educational systems, and national corporations, and published and lectured extensively throughout the United States and overseas on topics such as prehension (hand skills), vision, eye-hand coordination, and feeding problems in children with cerebral palsy, as well as handwriting and perceptual problems in children with learning disabilities.

The 21 video programs in DVD format describe normal and atypical development, assessment procedures, and intervention programs. All DVDs are shipped with a CD containing enclosures:
* suggestions for inservice procedures
* viewing and discussion guides
* reports or scored test booklets (if applicable)
* scripts for translation into other languages or for hearing-impaired viewers.
Other products (books, assessments, posters, activity charts, etc.) are correlated with many of the video programs.
