Predictors of Standardized Walking Obstacle Course outcome measures in children with and without developmental disabilities

Clinical balance assessment tools for children with hearing loss: a scoping review

Balance dysfunction exists in children with hearing loss, especially sensorineural loss, impacting on cognitive development, socio-emotional development and literacy. However, there is limited assessment of balance in this population, which further impedes childhood development. The objective of this review was to identify clinical, low- technology and inexpensive tools used to evaluate balance in children with hearing loss.

METHODS

A scoping review method with reference to the JBI, was used where a search was conducted on electronic databases including, but not limited to, EBSCOHost, MEDLINE, PubMED, Web of Science and Wiley. In addition, grey literature and hand searches were also used. The review included children between 3 and 15 years of age with hearing loss.

RESULTS

A total of 68 articles were found where 27% of the tests were norm-referenced tests, 64% were criterion referenced tests and 9% could not be identified.

CONCLUSION

Tests such as the Tandem gait test, Pediatric Balance Scale (PBS), Clinical Test of Sensory Interaction for Balance (mCTSIB)/Pediatric Version of Clinical Test for Sensory Interaction of Balance (P-CTSIB), Dynamic Gait Index and the Timed-up-and-Go were identified to be relatively inexpensive and low-technology clinical tools and have thus, been summarized in this review.

Psychometric properties of the Obstacles and Curb tests and their discriminative ability across functional levels in ambulatory children with spastic cerebral palsy

The Obstacles and Curb tests are timed walking assessments that have emerged from the Spinal Cord Injury Functional Ambulation Profile and have been modified for children; however, their psychometric properties have not been adequately investigated. The aim of this research was to examine the psychometric properties of the Obstacles and Curb tests for children with cerebral palsy (CP). This cross-sectional study included 68 children aged 6-12 years; there were 34 children with CP and 34 age- and sex-matched typically developing children. Validity was examined by correlation with the 10-m Walk Test (10-MWT), Modified Time Up and Go test (mTUG), and Pediatric Balance Scale (PBS). Differences in the Obstacle and Curb test scores were calculated between children with CP and typically developing children and within different Gross Motor Function Classification System (GMFCS) levels. Children with CP completed the tests twice within a 30-min interval in the same session. The tests showed significant strong to very strong correlations with the 10-MWT, mTUG, and PBS. The within-session reliability was excellent, typically developing children were significantly faster than children with CP with high sensitivity and specificity, and the time differed significantly within the GMFCS level. Thus, the Obstacles and Curb tests can be considered valid, reliable, and sensitive walking tests for ambulatory children with CP.

Reference data for performances on the standardized walking obstacle course in children developing typically

PURPOSE

To establish reference performance groups on the Standardized Walking Obstacle Course (SWOC) a pathway to screen ambulation for children developing typically.

METHODS

SWOC tests ambulation under three conditions: walk (W), walk with tray (WT) and walk wearing sunglasses (WG). One trial consisted of standing up, walking the course in one direction and sitting down. Children (n=355) completed two trials per condition. Trial measures included time to complete (seconds) and numbers of steps, stumbles, and steps off path.

RESULTS

Trial 1 and trial 2 for time and number of steps are significantly different (p=0.0005), but highly correlated (r=0.93 and r=0.96) therefore their average was used to establish reference data. Gender was not a significant factor. Age and height predict performances in all conditions, but measures between age groups were not always significantly different. Significant different measures by height groups could be established across all conditions, therefore reference data was established using three height groups.

CONCLUSION

Reference values will assist clinicians to compare a child's performance on the SWOC based on an individual height because this can vary within and between ages thus screening for possible ambulation limitations.
