International Delphi Recommendations for Pediatric Lower Limb Neurological Test Protocols for Muscle Strength, Reflexes, and Tactile Sensitivity.

PURPOSE: To gain consensus from physical therapists on pediatric lower limb neurological tests of muscle strength, tactile sensitivity, and reflexes. METHODS: A Delphi technique was used for 2 sequential questionnaire rounds to gain consensus from a panel of pediatric physical therapists (n = 28). Physical therapists rated their agreement to items from statements on pediatric lower limb neurological tests, their protocols, and interpretation using a 6-point Likert scale. RESULTS: Ninety percent of items gained consensus: 80% on pediatric lower limb neurological tests, 88% on test protocols, and 92% on test interpretation. Fifty-one percent of items had high agreement and high importance. CONCLUSION: There is variability in pediatric neurological tests used, their protocols, and interpretation. Identification of items with high agreement and importance is the first step to develop a standardized lower limb neurological assessment for pediatric clients of varying ages and diagnoses.

Perceived Barriers, Enablers, and Modifications to Tests Assessing Pediatric Lower Limb Neurological Impairment: An International Delphi Survey.

OBJECTIVES: Accurate, clinically meaningful outcome measures that are responsive to change are essential for selecting interventions and assessing their effects. Little guidance exists on the selection and administration of neurological impairment tests in children with a neurological condition. Clinicians therefore frequently modify adult assessments for use in children, yet the literature is inconsistent. This study aims to establish consensus on neurological conditions most likely to require neurological impairment test in pediatrics and the barriers, enablers, and modifications perceived to enhance test reliability. METHODS: Over a 2-round modified Delphi study, a panel of experts (n = 24) identified neurological conditions perceived to typically require pediatric neurological testing and the modifications to address barriers/enablers to testing. Experts comprised physical therapists with evidence of advanced training or research in pediatrics. Using a 6-point Likert scale (6 = strongly agree, 5 = agree, 4 = somewhat agree, 3 = somewhat disagree, 2 = disagree, 1 = strongly disagree), experts rated statements from existing literature. Thematic analyses were conducted on responses to open-ended questions. A priori consensus was pre-set at 65% agreement/disagreement. Median, mode, and interquartile ranges estimated perceived importance. Cessation was pre-determined by non-consensus items <10% and panel fatigue. RESULTS: Experts reached consensus on 107/112 (96%) items, including identifying 25/26 (96%) neurological conditions they perceived to require routine neurological testing. Experts strongly agreed with high importance that appropriately trained, experienced therapists are less variable when testing children. Communication modifications were perceived as most important. CONCLUSION: High levels of consensus support the use of lower limb neurological testing in a range of pediatric neurological conditions. Trained clinicians should document modifications such as visual aid use. Using recommended modifications could encourage consistency among clinicians. IMPACT: This is the first study to our knowledge to identify the barriers and enablers to pediatric neurological testing. Barriers and enablers were partially addressed through suggested modifications. Further rigorous examination of these modifications is required to support their use. LAY SUMMARY: This study supports that clinicians should adapt their communication for children and young people with neurological problems to include visual aids and equipment demonstration.

Clinimetric properties of lower limb neurological impairment tests for children and young people with a neurological condition: A systematic review.

BACKGROUND: Clinicians and researchers require sound neurological tests to measure changes in neurological impairments necessary for clinical decision-making. Little evidence-based guidance exists for selecting and interpreting an appropriate, paediatric-specific lower limb neurological test aimed at the impairment level. OBJECTIVE: To determine the clinimetric evidence underpinning neurological impairment tests currently used in paediatric rehabilitation to evaluate muscle strength, tactile sensitivity, and deep tendon reflexes of the lower limb in children and young people with a neurological condition. METHODS: Thirteen databases were systematically searched in two phases, from the date of database inception to 16 February 2017. Lower limb neurological impairment tests were first identified which evaluated muscle strength, tactile sensitivity or deep tendon reflexes in children or young people under 18 years of age with a neurological condition. Papers containing clinimetric evidence of these tests were then identified. The methodological quality of each paper was critically appraised using standardised tools and clinimetric evidence synthesised for each test. RESULTS: Thirteen papers were identified, which provided clinimetric evidence on six neurological tests. Muscle strength tests had the greatest volume of clinimetric evidence, however this evidence focused on reliability. Studies were variable in quality with inconsistent results. Clinimetric evidence for tactile sensitivity impairment tests was conflicting and difficult to extrapolate. No clinimetric evidence was found for impairment tests of deep tendon reflexes. CONCLUSIONS: Limited high-quality clinimetric evidence exists for lower limb neurological impairment tests in children and young people with a neurological condition. Results of currently used neurological tests, therefore, should be interpreted with caution. Robust clinimetric evidence on these tests is required for clinicians and researchers to effectively select and evaluate rehabilitation interventions.

Paediatric terminology in the Australian health and health-education context: a systematic review.

AIM: This study aimed to identify paediatric terminology used in the Australian health and health-education context, propose a standardized framework for Australian use, and compare it with a US-based framework. METHOD: Australian health and health-education websites were systematically searched using a novel hierarchical domain-specific search strategy to identify grey literature containing paediatric terminology. Webpages published from 2009 to February 2014, with a '.gov.au' or '.edu.au' domain and no advertising, were included. Paediatric terms were analysed with power-law distributions. Age definitions were grouped using a chi-squared test automatic interaction detection analysis (p<0.05). RESULTS: In total, 34 paediatric terms and 197 unique age definitions were identified in 613 webpages. Terms displayed a language distribution, although definitions had semantic and lexical ambiguity. Age definitions were divided into four statistically different groups (F=245.3, p<0.001). Four paediatric terms with distinct age definitions were proposed based on Australian data: 'infant: 0 to <1 year', 'early childhood: 1 year to <5 years', 'child: 5 years to <13 years', and 'young person: 13 years to <22 years'. These recommendations were broader than the US-based comparison. INTERPRETATION: This is a starting point for standardizing Australian paediatric terminology, and a method for exploring paediatric terminology in other countries.
