Visual perception difficulties are common in children with cerebral
palsy - hemiplegia, however it is not known which assessment tool is the best for
this population. This systematic review evaluates the clinimetric properties of
visual perception assessments for children with hemiplegia. METHOD: Databases
were searched for assessments that: (i) measured visual perception; (ii) were
reported in studies with children with hemiplegia and (iii) had clinimetric data
available to assessors. RESULTS: Three assessments met criteria: the Test of
Visual Perceptual Skills (TVPS), Motor-Free Visual Perceptual Test (MVPT) and
Developmental Test of Visual Perception (DTVP). Factor analysis has been
completed for the TVPS and DTVP, with both assessments and especially the TVPS,
demonstrating some subtests that do not load significantly for the first factor
of motor-free visual perception. All three assessments demonstrate variable
construct and criterion validity with other clinical assessments. The DTVP, MVPT
and TVPS demonstrate high test-retest reliability for total scores, but
individual TVPS subtests are less reliable. CONCLUSIONS: The MVPT and DTVP show
the best clinimetric data, however, less research has been completed on these
tests than the TVPS. Further research is required to confirm the validity and
reliability of the MVPT and DTVP for children with hemiplegia.
