Developing the Observatory Test of Capacity, Performance, and Developmental Disregard (OTCPDD) for Children with...

Area of Science:

• Pediatric Rehabilitation
• Occupational Therapy
• Motor Function Assessment

Background:

• Children with cerebral palsy (CP) often exhibit impaired upper limb function, impacting their daily routines.
• Accurate assessment of affected upper limb use in daily activities is crucial for effective intervention.
• Existing tools may not fully capture the nuances of capacity, performance, and developmental disregard in hand function.

Purpose of the Study:

• To develop and validate the Observatory Test of Capacity, Performance, and Developmental Disregard (OTCPDD).
• To measure the amount and quality of affected upper limb use in the daily routines of children with CP.
• To establish a reliable and valid observational assessment for pediatric upper limb function.

Main Methods:

• Recruited 48 participants: 24 children with CP and 24 typically developing children.
• Administered the OTCPDD twice (spontaneous and forced use conditions) to children with CP.
• Utilized the Pediatric Motor Activity Log-Revised (PMAL-R) for parent-reported data and assessed OTCPDD's internal consistency, reliability, and validity.

Main Results:

• The OTCPDD demonstrated high internal consistency (Cronbach's alpha > 0.9) and excellent intrarater and interrater reliability (> 0.9).
• Convergent validity was supported by significant correlations between OTCPDD and PMAL-R scores.
• Discriminant validity was confirmed by significant differences in OTCPDD scores between children with CP and typically developing peers (p<0.05).

Conclusions:

• The OTCPDD is a reliable and valid observation-based assessment tool for children with CP.
• The OTCPDD effectively captures bimanual daily living activities, reflecting affected hand function (capacity, performance, developmental disregard).
• This assessment provides valuable insights into the functional use of affected upper limbs in children's everyday lives.
