Heterogeneity of Tasks and Outcome Measures in Dual Tasking Studies in Children With Cerebral Palsy: A Scoping Review.

OBJECTIVE: The aims of this scoping review are to examine the available literature regarding dual tasking in children with cerebral palsy (CP) and to identify and categorize both the motor and cognitive tasks and outcome measures used primarily through the International Classification of Functioning, Disability, and Health model. METHODS: Five electronic databases were searched. Studies were included if they: (1) were published in English; (2) included at least 1 group of children or adolescents with a diagnosis of CP; (3) assessed dual tasking as part of the study; (4) reported the method for performing the dual task; and (5) reported the outcome measures utilized. RESULTS: Twenty-three studies with 439 children with CP were included. All studies utilized motor activities as the primary task, including walking, balance, and a functional transition. Motor secondary tasks occurred in 10 studies, cognitive secondary tasks in 12 studies, and 1 study used both. Forty-one outcome measures over 23 studies assessed the body structure and function domain, 7 measures over 6 studies assessed activity limitations, and 2 outcomes over 2 studies assessed participation. CONCLUSION: The 23 included studies demonstrated heterogeneity in the age and function of participants, secondary tasks, and outcome measures. Future studies on dual tasking in children with CP should consider the difficulty of the primary motor or cognitive task and compare secondary tasks to establish this contribution to motor performance. Studies should incorporate activity and participation measures to assess meaningful functional outcomes. IMPACT: Children with CP experience challenges when exposed to dual task situations. This scoping review highlights the importance of considering multiple factors when designing dual tasking studies involving children with CP to facilitate results translation, improved participation, and enhanced function. Similarly, studies should utilize activity and participation outcomes to assess quality of life.

Concurrent and predictive validity of the Alberta Infant Motor Scale and the Peabody Developmental Motor Scales-2 administered to infants born preterm in Norway.

BACKGROUND: The correlation between the Alberta Infant Motor Scale (AIMS) and the Peabody Developmental Motor Scales-2 (PDMS-2) has not previously been assessed in Norwegian infants. Our purpose was to investigate the concurrent validity of the AIMS and the PDMS-2 in a group of high-risk infants, and to investigate the predictive validity of the two tests for atypical motor function at 24 months post term age (PTA). METHODS: This is a retrospective study of the AIMS and the PDMS-2 administered to infants born preterm with gestational age ≤ 32 weeks (n = 139) who had participated in a randomized controlled trial of early parent-administered physiotherapy. The infants' motor development had been assessed using the AIMS and the PDMS-2 at 6- and 12-months. The primary outcome was PDMS-2 at 24-months PTA. To explore the correlation between the two tests we used Spearman's rho. Bland Altman plots were used to detect if there were systematic differences between the measurements. Receiver-operating characteristics curves were used to calculate area under the curve as an estimate of diagnostic accuracy of the AIMS and the PDMS- with respect to motor outcome at 24 months. RESULTS: The correlation between the AIMS and the PDMS-2 (total motor and locomotion subscale), at 6 months, was r = 0.44 and r = 0.76, and at 12 months r = 0.56 and r = 0.80 respectively. The predictive validity for atypical motor function at 24 months, assessed using the area under the curve at 6- and at 12- months, was for the AIMS 0.87 and 0.86, respectively, and for the PDMS-2 locomotion subscale 0.82 and 0.76 respectively. CONCLUSION: The correlation between the AIMS and the PDMS-2 locomotion subscale, at 6- and 12- months PTA, was good to excellent in a group of infants born preterm in Norway. And the AIMS and the locomotion subscale of the PDMS-2 were equally good predictors for atypical motor outcomes at 24 months PTA. These findings indicate that the AIMS and the locomotion subscale of the PDM-2, could be used interchangeable when assessing motor development in infants at 6- or 12 months of age.

Motor control and skill acquisition in pediatric physical therapy: an enactive proposal.

Theories of motor control and skill acquisition strongly influence and guide various fields of clinical practice. In last decades, changes in theoretical frameworks related to the conceptualization of brain plasticity, functional structures within the child, and environment have led to a revision of therapy approaches progressing from therapist-driven to child-initiated approaches. Even though theoretical frameworks and clinical practice are closely linked to the child's body, the profession has paid less attention to theories concerning the body's role and status in interpersonal relationships when fostering motor control and skill acquisition in children. In this theoretical paper we discuss the theoretical frameworks of motor control and skill acquisition that currently guide clinical practice. Through highlighting valuable contributions of these theories, we explore theoretical and practical benefits pediatric physical therapy can acquire by taking an enactive approach as a means to bring the child as a subject into focus. We rely on enactive concepts of embodiment, autonomy, and participatory sense-making in our exploration to provide an extended understanding of motor control and skill acquisition shaping our beliefs about what counts in therapeutic encounters in pediatric physical therapy.

A systematic synthesis of qualitative studies on parents' experiences of participating in early intervention programs with their infant born preterm.

Early intervention programs involving both the parent and the infant born preterm have demonstrated positive effects on developmental outcomes for the children. However, studies have also shown that parental engagement and adherence when implementing intervention programs can be challenging. The aim of this review was to provide a comprehensive description and new insights into key messages gleaned from the parent reports on participating in early intervention with their infant born preterm; knowledge vital to facilitate implementation of early interventions into clinical practice when using a model of direct parent involvement. Early intervention is broadly defined as a multi-interdisciplinary field provided to children from birth to five years of age to foster child health, wellbeing, development, adapting parenting and family function. For this systematic synthesis we define early intervention as programs with specific activities completed with the infant during the first year after birth. We assembled qualitative interview studies on parents' experiences with participation in early intervention and applied Malterud's qualitative systematic meta-synthesis to synthesize and translate the original findings across studies. In the analysis we applied enactive concepts of embodiment, autonomy, participatory sensemaking, and agency. 10 qualitative studies were identified and included. The systematic synthesis reveals how parents' successful and meaningful participation in early intervention programs were facilitated by their "active embodied doing." The "embodied doing" appeared as the basis for the parents' sense-making processes, development of confidence, and the ability for parents to see new possibilities for actions within themselves, with and in the child. In that respect, a perception of mutuality in the interaction between parent, infant and interventionist was central. Consequently, an important consideration when implementing early intervention into clinical practice is to promote embodied parent-infant interactions as well as trust between the parent and the interventionist.

Eating and Drinking Ability Classification System to detect aspiration risk in children with cerebral palsy: a validation study.

This prospective study has two aims. The first aim is to assess the concurrent validity of the Eating and Drinking Ability Classification System (EDACS) as a means of identifying aspiration risk in children with cerebral palsy by using the Pediatric version of the Eating Assessment Tool (PEDI-EAT-10) as the reference test. The second aim is to investigate the relationship between the aspiration and non-aspiration groups using both the EDACS and the PEDI-EAT-10. Data were collected and analyzed from the EDACS and PEDI-EAT-10 using a convenience sample of 131 children with cerebral palsy and feeding problems (77 males, 54 females; median age 4.4 years [IQR 2.5 years]). Risk of aspiration was identified in 118 individuals using the PEDI-EAT-10 scores of ≥ 5 points. The EDACS proved to be a valid tool in identifying aspiration risk in children who are classified in EDACS levels III-V. There was a significant correlation between the EDACS and PEDI-EAT-10 (rs = 0.597, p < 0.001). The EDACS had 78% (95% CI = 71-86%) sensitivity and 92% (95% CI = 88-97%) specificity in identifying aspiration risk a positive predictive value of 0.99, a negative predictive value of 0.32, a positive likelihood ratio of 9.75, and a negative likelihood ratio of 0.24.   Conclusion: The EDACS is a useful clinical tool to identify aspiration risk in children with cerebral palsy. Children in EDACS levels III to V are at risk of aspiration. As time permits, we recommend the use of both tools, the EDACS and the PEDI-EAT-10, when making decisions regarding referral for an instrumented swallowing study. What is Known: • Approximately 50% of children with cerebral palsy have dysphagia. • The Eating and Drinking Ability Classification System (EDACS) can be used to classify eating and drinking efficiency and safety in children with cerebral palsy. What is New: • Based on ROC analysis, EDACS demonstrates sensitivity of 78% and specificity of 92% in clinical identification of aspiration risk. • The combined use of the EDACS and the Pediatric version of the Eating Assessment Tool is recommended to make decisions about referral for an instrumented swallow study.

Can items on the TIMP aide in determining the motor performance of children with severe cerebral palsy? A pilot study.

BACKGROUND: Assessing the functional level of children with severe cerebral palsy (CP) requires sensitive tools. In this study, an 'assessment tool' was developed based on the Test of Infant Motor Performance (TIMP) for this population and the reliability and validity evaluated. METHODS: Five physical therapists administered the 'assessment tool' to six children (3-6 years old with a diagnosis of CP, GMFCS Level V). Subtest I of the Gross Motor Function Measure (GMFM-88) was also administered. Intra- and inter-rater reliability were assessed, and the concurrent validity between the 'assessment tool' and GMFM-88 calculated. RESULTS: The intra-rater reliability, a comparison of the total scores on the 'assessment tool' (live test) and the videotaped rescoring of the same test one month later showed consistency among four of the five therapists (ICC = 0.7545 to 0.979). The inter-rater reliability varied on some of the items but the total score on the 'assessment tool' showed good reliability (ICC2,5 0.816). Scores of children with dyskinesia were less stable. The Spearman's rank correlation coefficient was not significant. Therapists provided recommendations for item revisions. CONCLUSION: Further development of an 'assessment tool' appears justified; a larger study using a version with revised administration guidelines and items should be undertaken to re-verify the psychometrics properties of the 'assessment tool.'

Assessing sensory processing differences in children with idiopathic toe walking: A pilot study.

Idiopathic toe-walking (ITW) refers to persistent walking without heel contact for unknown reasons. An underexplored area is the relationship of sensory processing to ITW. This study presents methods to assess sensory differences in individuals with ITW and summarizes results from a pilot testing of the measures. This pilot study included nine children and one young adult with ITW. Ten age-matched controls were recruited to provide a comparison group when norms were not available in the literature. The measures included in this study were as follows: sensory questionnaires; electrodermal activity response to sensory stimuli; monofilaments; biothesiometer; gait on different surfaces; NeuroCom® SMART Balance Master® Sensory Organization Test and Adaptation Test; and ankle position matching. All study procedures were completed in about 3 hours. Children as young as 4 years were able to complete the measures. We observed overall differences in sensory processing, specifically, higher Sensory Processing Measure scores (p = .011), higher resting electrodermal activity (p = .012), increases in heel-toe walking on novel surfaces (p = .034), and more falls with balance perturbation (p = .007) in individuals with ITW. A subset of individuals also showed tactile hyposensitivity (5 out of 10 in the ITW group) and poor equilibrium scores in the Sensory Organization Test (4 out of 9 in the ITW group, 1 unable to complete the test). Our results confirmed the heterogeneity in the etiology of ITW. We propose that further testing in sensory modulation, tactile processing, and vestibular processing is needed to fully explore the impact of sensory processing on children with ITW.

Two-year motor outcomes associated with the dose of NICU based physical therapy: The Noppi RCT.

BACKGROUND: Interventions involving both the parent and the preterm infant have demonstrated lasting effects on cognitive outcomes, but motor effects are less salient. It remains unclear when to commence early intervention and if dosages have impact on motor outcomes. AIMS: To examine the effect on motor performance at 24-months corrected age following a parent-administered intervention performed with infants born preterm in the NICU. Intervention dosing and longitudinal motor performance were also analyzed. STUDY DESIGN: Single-blinded randomized multicenter clinical trial. SUBJECTS: 153 infants born, gestational age ≤ 32 weeks at birth, were randomized into intervention or control group. OUTCOME MEASURES: Infant Motor Performance Screening Test, Test of Infant Motor Performance, Peabody Developmental Motor Scales-2. RESULTS: No significant difference was found between the intervention and the control group assessed with the PDMS-2 at 24-months CA. However, a significant positive association was found between dosing and the Gross Motor and Total Motor PDMS-2 scores. Analysis of longitudinal motor performance showed a decreasing motor performance between 6- and 24-months corrected age in both groups. CONCLUSIONS: There was no difference in motor performance between groups at 24-months corrected age. However, increased intervention dosage was positively associated with improved motor outcome.

The Significance of Touch in Pediatric Physiotherapy.

Change in theoretical framework over the last decades and recent research in pediatric physiotherapy, has created a debate surrounding therapeutic touch. What is the role of or is there a need for handling and hands-on facilitated guidance (facilitation)? Does it limit and/or interfere with children's learning and development? It is frequently argued that therapeutic touch represents a passive and/or static approach that restricts disabled children's participation during interaction and activity in clinical encounters leading to decreased home, school and community participation. Touch may even appear as coercive and controlling. In this context, therapeutic touch is largely associated with physical hands-on activities. However, therapeutic touch can also be understood as an intersubjective phenomenon that arises from a deep connection between movement, perception, and action. We believe the significance of therapeutic touch and its impact on physiotherapy for children has not been considered from this broader, holistic perspective. In this theoretical paper, we will apply enactive concepts of embodiment, sensory-motor agency, coordination, and emergence to explore the concept and importance of touch in physiotherapists' clinical face-to face encounters with children. We will frame the discussion within the context of the typical sensorimotor development of children from the fetal stage to birth on and into adulthood. Moreover, we will rely on biological, physiological, and phenomenological insights to provide an extended understanding of the importance of touch and the significance of touch in clinical practice.

Enactive explorations of children's sensory-motor play and therapeutic handling in physical therapy.

Introduction: In pediatric physical therapy, there is an ongoing debate about the use of therapeutic handling and its potential effects on motor learning. In this study, we build on enactive theoretical perspectives to explore the role of therapeutic handling in connection to children's sensory-motor play, engagement, and performance during a single physical therapy session. Material and methods: This is a qualitative study based on video observations of therapy sessions and interviews with 15 physical therapists (PTs) each treating two different children aged 0-3. The authors utilized a framework of co-reviewing, discussing, and reflecting on the sessions. Themes were identified and used to describe the ways by which PTs' therapeutic handling unfolds, with connections to theories on sensory-motor play and learning, along with enactive perspectives on embodiment, experience, mutual incorporation, and sense-of-agency. Results: The characteristics and purposes of therapeutic handling are presented in two main themes: (1) position and support, and (2) directing movement. We found that position and support promoted sensory-motor improvement when the PTs' handling aligned with the child's play interests and engagements. As part of play, the children used new and additional support surfaces to self-initiate better posture and movement solutions and reach play goals. The PTs' ways of directing movements varied. To awaken curiosity and induce a child's self-driven motor exploration the PT needs to be subtle, flexible, and precise in the directing of movement. This entails responsiveness to the child's signals and bodily know-how in the placing of hands and direction of pressure to enable the child to actively participate in and eventually self-drive movement. Discussion: Therapeutic handling that is mutually incorporated between PT and child can enrich the child's playing-to-learn-to-move process by providing novelty and facilitating the child's sense-of-agency in the self-initiated exploration and refinement of movement possibilities. In the PTs' effort to merge therapeutic handling with children's play, the momentum of interaction can open new therapeutic windows of movement experience and learning opportunities.

Body composition and neuromotor development in the year after NICU discharge in premature infants.

BACKGROUND: Hypothesis: neuromotor development correlates to body composition over the first year of life in prematurely born infants and can be influenced by enhancing motor activity. METHODS: Forty-six female and 53 male infants [27 ± 1.8 (sd) weeks] randomized to comparison or exercise group (caregiver provided 15-20 min daily of developmentally appropriate motor activities) completed the year-long study. Body composition [lean body and fat mass (LBM, FM)], growth/inflammation predictive biomarkers, and Alberta Infant Motor Scale (AIMS) were assessed. RESULTS: AIMS at 1 year correlated with LBM (r = 0.32, p < 0.001) in the whole cohort. However, there was no effect of the intervention. LBM increased by ~3685 g (p < 0.001)); insulin-like growth factor-1 (IGF-1) was correlated with LBM (r = 0.36, p = 0.002). IL-1RA (an inflammatory biomarker) decreased (-75%, p < 0.0125). LBM and bone mineral density were significantly lower and IGF-1 higher in the females at 1 year. CONCLUSIONS: We found an association between neuromotor development and LBM suggesting that motor activity may influence LBM. Our particular intervention was ineffective. Whether activities provided largely by caregivers to enhance motor activity in prematurely born infants can affect the interrelated (1) balance of growth and inflammation mediators, (2) neuromotor development, (3) sexual dimorphism, and/or (4) body composition early in life remains unknown.

Effects of a Parent-Administered Exercise Program in the Neonatal Intensive Care Unit: Dose Does Matter-A Randomized Controlled Trial.

BACKGROUND: Despite the risk of delayed motor development in infants born preterm, knowledge about interventions in the neonatal intensive care unitt (NICU) and the effects of dosing is sparse. OBJECTIVE: The objectives of this study were to examine the effectiveness of a parent-administered exercise program in the NICU on motor outcome at 3 months corrected age (CA) and the effect of dosing on motor performance. DESIGN: This was a randomized clinical trial. SETTING: The study was conducted at 3 university hospitals in Tromsø, Trondheim, and Oslo, Norway. PARTICIPANTS: A total of 153 infants with gestational age <32 weeks at birth were randomly assigned to intervention or control groups. INTERVENTION: A 3-week parent-administered intervention designed to facilitate movements in preterm infants was performed in the NICU. Parents were asked to administer the intervention 10 minutes twice a day. MEASUREMENTS: Test of Infant Motor Performance (TIMP) was used to assess short-term outcome at 3 months CA. RESULTS: No significant difference in the TIMP z-score was found between intervention and control groups at follow-up 3 months CA, but a significant positive relationship was found between total intervention dose and TIMP z-scores. The adjusted odds of having a clinical z-score < 0 at 3 months CA was about 6 times higher for infants with less than median intervention time than for infants with a longer intervention time. LIMITATIONS: The number of infants born before 28 weeks was small. A spillover effect in favor of the control group was possible. We do not know if the infants received physical therapy after discharge from the hospital. CONCLUSIONS: There was no difference in motor performance between the intervention group and the control group at 3 months CA. However, an increased intervention dose was positively associated with improved motor outcome.

Maximizing Participation During Walking in Children With Disabilities: Is Response to Unpredictability Important?

Walking ability is one of the primary components of human motor function, and interventions aimed at improving walking ability are common in physical therapy, particularly in children. One element encountered in a participatory, or natural, environment is unpredictability, defined as the presence of an unexpected obstacle, stimulus, or alteration of the environmental conditions. Little research has assessed the influence of unpredictability on biomechanical adaptations to walking in children who are developing typically or children with motor disabilities. A variety of impairments may result in an inadequate response to unpredictability, and we propose that there may be a relationship between response to an unpredictable visual cue and mobility-based participation.

Integrated approaches to physical Therapy education: a new comprehensive model from the University of Illinois Chicago.

Demand for physical therapists in the United States (U.S.) is currently robust and expected to grow further. There are currently 228 physical therapy programs accredited by the Commission on Accreditation in Physical Therapy Education (CAPTE), and 30 more are in development in the U.S.; 29,246 students are currently enrolled in these programs (2014-2015 data). A shortage of physical therapy faculty with an advanced doctoral degree (i.e., PhD, EdD, DSc) is a primary concern for these programs. Specialized residency and fellowship training in physical therapy continue to expand, preparing professionals to deliver advanced clinical care. The American Board of Physical Therapy Residency and Fellowship Education (ABPTRFE) reports that there are currently 179 accredited residency programs and 35 accredited fellowship programs in the U.S. A number of academic physical therapy programs also currently operate a clinical faculty practice. Currently, these aspects and trends in physical therapy education, advanced training, and clinical practice, for the most part, lack synergy and connectivity, in both planning and implementation amongst the various components. This professional theoretical article describes a novel model for academic physical therapy, with potential transformative implications for entry-level physical therapy education, advanced clinical training, and academic preparation.

Early Parent-Administered Physical Therapy for Preterm Infants: A Randomized Controlled Trial.

OBJECTIVE: To investigate the short-term effect of parent-administered physical therapy in the preterm period on motor performance in medically stable infants. METHODS: This study was a pragmatic, multicenter, randomized controlled trial including 153 infants born at gestational age ≤32 weeks and randomized to an intervention (n = 74) or a control (n = 79) group. The intervention promoted postural control, head control, and midline orientation. Parents, supervised by a physical therapist, conducted the intervention 10 minutes twice a day for 3 weeks from 34 to 36 weeks' postmenstrual age (PMA). The control group received usual care. The Test of Infant Motor Performance Screening Items was used at baseline and the Test of Infant Motor Performance postintervention (week 37 PMA). Linear mixed models were used to assess change in motor performance between groups from 34 to 37 weeks' PMA by using z scores. Effect size was measured by using Cohen's d. RESULTS: The mean baseline z score was 0.06 (95% confidence interval, -0.48 to 0.60). After the intervention, there was a significant group difference, indicating a change in motor performance from week 34 to 37 PMA favoring the intervention group. The estimated difference in z scores was 0.42 (95% confidence interval, 0.13 to 0.72; P = .005), and the effect size was 0.40. CONCLUSIONS: Parent-administered physical therapy conducted before term-equivalent age improved motor performance at 37 weeks' PMA more than conventional care. All infants will be followed up until 2 years' corrected age to evaluate the long-term effects of this brief intervention.

Test-retest reliability of the Test of Infant Motor Performance Screening Items in infants at risk for impaired functional motor performance.

OBJECTIVE: To examine test-retest reliability of the TIMPSI in infants at risk for impaired functional motor performance. METHODS: The TIMPSI was administered twice to 51 infants from two different hospitals in Norway. RESULTS: The intra-class correlation coefficient was 0.99. CONCLUSION: Test-retest reliability of the TIMPSI was excellent.

Study protocol: an early intervention program to improve motor outcome in preterm infants: a randomized controlled trial and a qualitative study of physiotherapy performance and parental experiences.

BACKGROUND: Knowledge about early physiotherapy to preterm infants is sparse, given the risk of delayed motor development and cerebral palsy. METHODS/DESIGN: A pragmatic randomized controlled study has been designed to assess the effect of a preventative physiotherapy program carried out in the neonatal intensive care unit. Moreover, a qualitative study is carried out to assess the physiotherapy performance and parents' experiences with the intervention. The aim of the physiotherapy program is to improve motor development i.e. postural control and selective movements in these infants. 150 infants will be included and randomized to either intervention or standard follow-up. The infants in the intervention group will be given specific stimulation to facilitate movements based on the individual infant's development, behavior and needs. The physiotherapist teaches the parents how to do the intervention and the parents receive a booklet with photos and descriptions of the intervention. Intervention is carried out twice a day for three weeks (week 34, 35, 36 postmenstrual age). Standardized tests are carried out at baseline, term age and at three, six, 12 and 24 months corrected age. In addition eight triads (infant, parent and physiotherapist) are observed and videotaped in four clinical encounters each to assess the process of physiotherapy performance. The parents are also interviewed on their experiences with the intervention and how it influences on the parent-child relationship. Eight parents from the follow up group are interviewed about their experience. The interviews are performed according to the same schedule as the standardized measurements. Primary outcome is at two years corrected age. DISCUSSION: The paper presents the protocol for a randomized controlled trial designed to study the effect of physiotherapy to preterm infants at neonatal intensive care units. It also studies physiotherapy performance and the parent's experiences with the intervention. TRIAL REGISTRATION: ClinicalTrials.gov NCT01089296.

Dance program for physical rehabilitation and participation in children with cerebral palsy.

Objective: This pilot study aimed to examine a classical ballet program created for children with cerebral palsy (CP) as an emerging physical rehabilitation modality. The main program goals were to promote participation and to provide an artistic, physically therapeutic activity. Methods: The study was conducted in collaboration with a tertiary rehabilitation hospital, one outpatient physical therapy clinic, and one community center. As a pilot exploratory study, the research design included questionnaires to assess the participants' (children (n = 16), parents (n = 16), and therapists (n = 13)) perceptions on the therapeutic benefit of the dance program. A binomial statistical model was adopted for the analysis of the results. Results: Main results were that the children reported high enjoyment level (p < .0001) and desire for more classes (.0001); the parents reported perceived therapeutic benefit (p < .0001); and the therapists viewed the class as a positive adjunct to therapy (p < .0001). Conclusions: The main limitation of this work was the utilization of subjective outcome measures. However, this is the first step toward the development of objective measures of an intervention that, to our knowledge, has not been analyzed in the past. We conclude that the program has the potential of developing into an evidence based rehabilitation resource for children with CP.
