The SOSI-M is a new nationally standardized assessment of sensory-based motor skills, based in Ayres Clinical Observations, and developed by well-regarded experts in sensory integration.

The SOSI-M includes 14 sets of administered items that assess proprioception, vestibular processing, motor planning, and postural control.

  •     Romberg (firm and soft surface, eyes open and closed)
  •     Heel to Toe (firm and soft surface, eyes open and closed)

Comprehensive Observations of Proprioception (COP-R)

In conjunction with the SOSI-M, the COP-R, a behavioral observation tool, was developed to provide essential information about a child’s proprioceptive processing. The COP-R is comprised of 18 items and compares a child’s observed skills to typical children their age. This tool provides information about the motor and behavioral skills linked to proprioceptive processing. It is one of the first tools to provide a systematic way to measure proprioception in a clinical setting.

SOSI-M kit includes: Manual, Spanish Administration Instructions, Quick Start Administration Guide, 25 Record Forms, 25 Comprehensive Observations of Proprioception (COP-R) Forms, one 15 cm and one 20 cm square, one 8-1/2 x 11 projected actions target, tennis ball, pencil with pencil topper, stopwatch, tote bag and Airex foam mat.
