Clinical Observations of Motor nd and Postural Skills

Clinical Observations of Motor nd and Postural Skills- 2 Edition (COMPS-2) Becca Price & Shelby Berthelot

Purpose • Performance based screening test • Descriptive measure that helps identify presence of motor problems with a postural component • Helps identify if additional assessments need to be performed • Determine type of intervention approach to use • Children ages 5 -15

Items • 6 items: Slow Movements Rapid Forearm Rotation Finger-Nose Touching Prone Extension Posture Asymmetrical Tonic Neck Reflex Supine Flexion Posture

Testing Procedures • Recommended to perform 6 tasks in order • Last 3 tasks must be performed in order • Use standardized methods and exact wording in bold • Therapist performs task first then instructs them to imitate

Test Development and Standardization • Initial Test – Went from 19 items to 6 – Used by experienced pediatric Ots in 2 cities – 123 children age 5 to 9. 11 , 67 with DCD and 56 with no know motor problem • Upward age extension – 261 children between age 10 -16

Psychometric Properties Reliability: Test-Retest =. 92 Interrater • (4 different raters) =. 87 Internal Consistency =. 75 • Age 5 - 9. 11 =. 77 • Age 10 - 15. 11 =. 69 Validity: Content- established by expert opinion Construct- empirical item analysis Test Sensitivity: 100% for ages 5, 8, 9 82% for ages 6 & 7 Low percentage for ages >9. 11 Criterion Concurrent- BOTMP subtests, Developmental Coordination Disorder Questionaire Predictive- Correctly classified ~ 80% of the time

Test Length and Cost • Takes about 15 -20 minutes to administer and score • Cost: – Manual = $36 – Score Sheets = $18 for 20 sheets – Therapro. com

Scoring

Test Results • Less than a 0 indicates problems in motor and postural skills • Greater than a 0 indicates normal functioning in motor and postural skills • A weighted score is given for each of the 6 items and a weighted total score is given

Areas of Occupation Addressed • Play • Functional Mobility

Assessment Approach • Bottom up – Tests the different components of motor control – Measures: • • • Move slowly and symmetrically Cerebellar-vestibular integrity Cerebellar coordination Vestibular-proprioceptive processing dysfunction Degree of ATNR present Somato-dyspraxia

Where the Tool is Used • Rehabilitation Clinic/ Health Care setting • Education Setting • Private Pediatric Clinic

Frame of Reference • Motor control – Movement disorder – Postural stability – Motor coordination

Measurement Concerns • The assessment does not take into consideration children who have neurological or neuromotor problems, such as cerebral palsy or epilepsy. • The results do not return normative data in the way of age equivalence. • The assessment is not meant to measure change in motor function over time.
