Summary
This summary is machine-generated.

The Seated Postural and Reaching Control test (SP&R-co) reliably measures postural control and reaching in children with cerebral palsy (CP). This new tool helps therapists objectively assess limitations in children with CP.

Area of Science:

  • Pediatric Rehabilitation
  • Neuromotor Assessment
  • Cerebral Palsy Research

Background:

  • Children with moderate-severe cerebral palsy (CP) experience significant deficits in postural control, impacting daily activities like reaching.
  • Existing clinical measures may not adequately capture the nuances of postural imbalance and associated reaching limitations in this population.
  • Objective and reliable assessment tools are crucial for effective intervention planning in pediatric CP.

Purpose of the Study:

  • To introduce and validate the Seated Postural and Reaching Control test (SP&R-co) as a clinical measure.
  • To objectively identify dimensions of postural imbalance and reaching limitations in children with CP.
  • To provide therapists with a reliable tool for assessing seated postural control and reaching.

Main Methods:

  • The SP&R-co documentation was developed for test validity and rater training.
  • Internal consistency and rater reliability (inter-rater and intra-rater) were assessed using Cronbach's alpha and Intraclass Correlation Coefficients (ICC).
  • Construct and concurrent validity were evaluated using motor classification systems and performance tests.

Main Results:

  • The SP&R-co demonstrated acceptable-to-good internal consistency (α = 0.76-0.84) and excellent item interrelatedness (α = 0.82-0.97).
  • Rater reliability was fair to excellent for item-by-item assessment (ICC = 0.41-0.92), and good-to-excellent for overall dimensions (Inter-rater ICC = 0.68-0.86; Intra-rater ICC = 0.64-0.95).
  • Construct and concurrent validity showed moderate-to-excellent correlations (r = 0.49-0.88).

Conclusions:

  • The SP&R-co is a reliable and valid instrument for assessing seated postural and reaching control in children with CP.
  • The test provides objective quantification of functional limitations, aiding therapists in clinical decision-making.
  • This tool supports the development of targeted interventions for improving motor function in pediatric CP.
