Clinical Expertise Behind the OTvest®

Ms. VandenBerg received advanced training directly from world-renowned neurologist and physiotherapist Karel and Berta Bobath in Neuro-Developmental Treatment (NDT) regarding how to improve motor control. Her background also includes extensive sensory-motor training. She served for 16 years on a school district Autism Diagnostic Team.

In addition, Ms. VandenBerg served for six years on the Steering Committee for the Michigan Alliance for School Physical and Occupational Therapists, contributing to professional leadership and clinical advancement in the field.

Her research examining on-task attention in children with ADHD wearing a weighted vest—with weights strategically positioned on the body—compared to attention without a weighted vest was published in the American Journal of Occupational Therapy.
