Educational programs for learning to observe movement quality in physical therapy: a design-based research approach.

Introduction: Movement observation is a core aspect in physical therapists' diagnosis to determine which interventions are adequate to improve functional abilities. The aim of this study was to derive design principles for an educational program for the development of observational skills.Methods: We used a qualitative approach within a design-based research methodology. In four rounds, 8 physical therapy students, 16 teachers, and 9 practitioners participated in five Nominal Group Technique meetings and six interviews. Meetings and interviews were transcribed verbatim and analyzed using thematic analysis.Results: We identified three themes, each with several design principles: (1) didactics; (2) professional content; and (3) conditions for optimal learning. We developed a proto-theory underpinned with underlying educational theories.Conclusions: To learn observational skills, students, facilitated by an experienced teacher, need to take the lead in their own learning process. This might imply a need for additional training for teachers. A realistic context is a precondition for learning; it might be necessary to increase possibilities for observations in clinical contexts or to invest in training for (simulated) patients as participants in education. Further research is needed to test the applicability of the design principles and a proto-theory for other professionals with a focus on observation and analysis of movements.

Individual longitudinal neurodevelopmental trajectories of children treated with hypothermia for perinatal asphyxia from 3 months to 5 years of age.

BACKGROUND: Hypothermia for perinatal asphyxia is a common treatment to decrease morbidity. This study aims to describe a) individual longitudinal neurodevelopmental trajectories over 5 years in children with perinatal asphyxia treated with hypothermia and b) the correlation between movement quality at 3 months and motor developmental outcomes at 5 years of age. METHODS: In this longitudinal cohort study, 18 children (12 male) were assessed at 3 (t1), 6 (t2), 12 (t3), and 24 (t4) months, and at the age of 5 (t5) years, with standardized norm-referenced tests. RESULTS: Six children showed abnormal movement quality assessed with General Movements (t1) and all showed severe neurodevelopmental disabilities at t5. The 12 children without severe disabilities, showed a significant normalization of z-scores over the five assessment points (linear mixed model analysis). At t5, four of these children scored mildly delayed motor or cognitive development. CONCLUSION AND IMPLICATIONS: Children without anomalies on the MRI before hospital discharge and normal movement quality at 3 months of age showed normal neurodevelopment at the age of 5, however, individual motor trajectories showed variability over time. Presents of abnormal GMs tend to detect CP and developmental problems, advocating a developmental surveillance to determine need for early intervention.

Reliability and Responsiveness of the Observable Movement Quality Scale for Children with Mild to Moderate Motor Impairments.

AIM: The Observable Movement Quality (OMQ) scale measures generic movement quality and is used alongside standardized age-adequate motor performance tests. The scale consists of 15 items, each focusing on a different aspect; together, the entire construct of movement quality is assessed. This study aimed to determine interrater and intrarater reliability, and responsiveness of the OMQ scale. METHODS: A prospective intervention study with pre-post design in pediatric physical therapy practices. For interrater reliability, 3 physical therapists observed video-recorded motor assessments of 30 children with mild to moderate motor impairments -aged 4 to 12 years-using the OMQ scale. One therapist scored baseline assessment a second time for intrarater reliability, and to calculate smallest detectable change (SDC). Responsiveness (n = 28) was tested by comparing outcomes before and after intervention. RESULTS: Interrater reliability was moderate to good (ICC2,1: 0.79); intrarater reliability was high (ICC2,1: 0.97). Responsiveness results revealed an SDC of 2.4 and a minimal important change of 2.5; indicating sufficient validity in differentiating groups of children showing improved versus unchanged movement quality. CONCLUSION: The OMQ scale is reliable and responsive to change when used to assess movement quality in clinical practice for children with mild to moderate motor impairments, aged 4-12 year.

Construct Validity of the Observable Movement Quality Scale in Pediatrics: Hypothesis Testing of a Formative Measurement Model.

BACKGROUND: The Observable Movement Quality (OMQ) Scale measures generic movement quality. Each item of the OMQ Scale focuses on a different element; together, the 15 items assess the whole construct of movement quality. OBJECTIVE: The aim of this study was to determine the construct validity of the OMQ Scale using 7 hypotheses defined to conform to the Consensus-Based Standards for the Selection of Health Measurement Instruments. DESIGN: This was an exploratory validation study. METHODS: A pediatric physical therapist assessed motor performance in 101 children using an age-specific motor test and the OMQ Scale. The direction, magnitude, and rationale for 7 hypotheses, which concerned relationships (n = 2), probability of low scores (n = 4), and difference between diagnosis subgroups (n = 1), were defined. RESULTS: The results confirmed 6 of the 7 hypotheses, indicating sufficient construct validity. Significant positive relationships were found between OMQ Scale total scores and the severity of motor disabilities (r = 0.72) and z scores on motor tests (r = 0.60). Probabilities for low scores on OMQ Scale items-exceeding the chi-square critical value-were confirmed for children diagnosed with spasticity, psychomotor retardation, mitochondrial diseases, and ataxia; however, probabilities for low OMQ Scale item scores on strength regulation in children with ataxia were not confirmed. OMQ Scale total scores for children who were not ambulatory because of neurological conditions were significantly different from those for children who were not ambulatory because of fatigue (r = 0.66). LIMITATIONS: The sample of children was based on theoretical assumptions about relevant variations in clinical representations; on the basis of the results, it appears that children with low strength regulation were underrepresented. CONCLUSION: The confirmation of nearly all hypotheses supported the validity of the OMQ Scale for measuring movement quality in clinical practice in addition to standardized age-adequate motor performance tests.

Interrater Reliability of the Observable Movement Quality Scale for Children.

Purpose: The authors investigated the interrater reliability, the standard deviation of the random measurement error, and the limits of agreement (LoA) of the Observable Movement Quality (OMQ) scale in children. Movement quality is important in the recognition of motor problems, and the OMQ scale, a questionnaire used by paediatric physical therapists, has been developed for use with an age-specific motor test to observe movement quality and score relative to what is expected for a child's age. Method: Paediatric physical therapists (n=28; 2 men, 26 women) observed video-recorded assessments of age-related motor tests in children (n=9) aged 6 months to 6 years and filled in the OMQ scale (possible score range 15-75 points). For our analyses, we used linear mixed models without fixed effects. Results: The interrater reliability was moderate (intra-class correlation coefficient [ICC2,1]: 0.67, 95% CI: 0.47, 0.88); neither work setting nor work experience exerted any influence on it. The standard deviation of the random measurement error was 5.7, and the LoA was 31.5. Item agreement was good (proportion of observed agreement [Po] total 0.82-0.99). Conclusion: The OMQ scale showed moderate interrater reliability when being used by therapists who were unfamiliar with the questionnaire and who had received only 2 hours of training. Feedback from the participants suggested a need for more comprehensive training in using the OMQ scale in clinical practice.

Objectif : étudier la fiabilité interévaluateur, l'écart-type (ÉT) de l'erreur de mesure aléatoire et les limites de concordance (LdC) de l'échelle de qualité de mouvements observables (QMO) chez les enfants. La qualité des mouvements est importante pour déceler les problèmes moteurs, et l'échelle de QMO, un questionnaire auquel recourent les physiothérapeutes pédiatriques, a été mise au point pour être utilisée conjointement avec un test de motricité adapté à l'âge afin d'observer la qualité des mouvements et un score relatif aux attentes en fonction de l'âge de l'enfant. Méthodologie : les physiothérapeutes pédiatriques (n=28; deux hommes, 26 femmes) ont observé des évaluations enregistrées sur vidéo des tests de motricité adaptés à l'âge chez des enfants (n=9) de six mois à six ans et ont rempli l'échelle de QMO (éventail possible des résultats de 15 à 75 points). Dans les analyses, les chercheurs ont utilisé les modèles linéaires mixtes sans effet fixe. Résultats : la fiabilité interévaluateur était modérée (coefficient de corrélation intraclasse [CCI2,1] : 0,67, IC à 95 % : 0,47, 0,88); ni le lieu de travail ni l'expérience de travail n'y exerçait d'influence. L'ÉT de l'erreur de mesure aléatoire était de 5,7, et la LdC, de 31,5. La concordance des points était bonne (proportion du total de concordance observée [Po] : 0,82 à 0,99). Conclusion : l'échelle de QMO a révélé une fiabilité interévaluateur modérée lorsqu'elle était utilisée par des physiothérapeutes qui ne connaissaient pas le questionnaire et dont la formation s'était limitée à seulement deux heures. Selon les commentaires de participants, il faudrait une formation plus approfondie pour utiliser l'échelle de QMO en pratique clinique.
