Structured Observations of Sensory-Motor Integration (SOSI-M) and Comprehensive Observations of Proprioception (COP-R)

Standardized Administration, Scoring, and Clinical Interpretation

Hourly load:
The course has 7 synchronous or face-to-face hours in four modules of 1 to 2 hours each, and 9 asynchronous hours that participants complete online.
Participants can review recorded presentations in preparation for synchronous encounters with the authors of both instruments.

Asynchronous: Participants review presentations, videos and learning activities.

Professional with a university degree in Occupational Therapy or Physical Therapy
It is recommended that participants have access to a SOSI-M KIT

Course Description:

This course covers the theory, administration, scoring, and interpretation of the Structured Observations of Sensory-Motor Integration (SOSI-M) and the Comprehensive Observations of Proprioception (COP-R). 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 with numerous pilot studies in more than 6 countries. 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 pre-adolescents. 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.

LINKED: Breathing & Postural Control – Part 2


Friday, March 24th, 2023 with 7:30 am check-in; course 8 am – 5 pm AND Saturday March 25th, 2023 with 7:30 am check-in; course 8 am – 2 pm


18333 S. Main St., Gardena, CA

Course Description:

This course, developed by Mary Massery, proposes a new definition of “core stability;” redefining it as the dynamic control of trunk pressures to optimize postural stability (balance). Dr. Massery’s “soda pop can model” links breathing mechanics to postural control using multi-system interactions. The speaker presents novel research demonstrating the role of vocal folds as postural stabilizers, extending the concept of “core stability” from the vocal folds on the top of the trunk to the pelvic floor on the bottom. In Part 2, the focus is ssessing “normal” breathing patterns, neuromotor breathing retraining techniques and manual assistive cough techniques during hands-on labs. Multiple clinical cases will be used to cement the concepts. The course is applicable for any pediatric or adult patient (or therapist) who breathes!

Instructor: Vincent Leddy, PT, DPT, PCS

Dr. Leddy competed his BS in Physical Therapy in the Netherlands in 1988, his DPT at Rocky Mountain University in 2017, and his APTA certification as a Pediatric Clinical Specialist in 2018. In 2019, he completed a 2-year invited apprenticeship to become Mary Massery’s third certified faculty member!
Dr. Leddy’s interest in breathing and postural control extends beyond pediatrics and includes complex neurological patients, adult orthopedic patients, and elite level ballerinas. He is a life-long learner and teacher, focusing on creating long-term benefits for his clients, such as with his “Now What?” peer project pairing young adults with cerebral palsy (CP) with adult mentors with CP.
Vincent’s proudest “Mary Massery moment” was using Dr. Massery’s concepts to improve the breathing patterns of an infant with developmental delays caused by gastric reflux and multi-system consequences. He would not have recognized this link without the mentorship he received in his faculty training. He can’t wait to show other therapists how to apply these concepts to their patients.

Registration Fee: $450.
