Administration Instructions in English and Spanish
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)
Standing on One Foot (eyes open and closed)
Modified Postural Schilder’s Arm Extension Test
Series of Jumps (jumping jacks; symmetric and reciprocal stride jumps)
High Kneeling (right and left weight shift and reach)
Ocular Movements (vertical and horizontal)
Slow Ramp Movements
Sequential Finger Touching
Diadochokinesis (right, left, and bilateral)
Projected Actions in Time and Space (ball in the air and ball against the wall)
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.
Also included in each kit: A redemption code card for 10 free SOSI-M scoring reports and 10 free COP-R scoring reports
