Research summit III proceedings on dosing in children with an injured brain or cerebral palsy: executive summary

Defining paediatric neurorehabilitation: You cannot improve what you cannot characterize

Neurorehabilitation is the primary therapy for neurological impairment in children, yet its potential to achieve change remains incompletely understood and probably underestimated. Understanding 'the difference neurorehabilitation can make' against a background of neurological repair and recovery as well as ongoing neurological development is an enormous challenge, exacerbated to no small extent by the lack of a 'common currency' for the description and measurement of the neurorehabilitation services a child is receiving. This review addresses attempts to parse neurorehabilitation treatment content in theoretically and mechanistically valid ways that might help address this challenge.

Spreading Standardized Documentation of Pediatric Occupational and Physical Therapy Dose: A Quality Improvement Initiative

IMPORTANCE

Clinicians and researchers can leverage clinical documentation of therapy services for quality improvement and research purposes. However, documentation is often institution specific and may not adequately capture the dose of therapy delivered, thus limiting collaboration.

OBJECTIVE

To implement documentation of pediatric occupational and physical therapy dose from one institution to another institution. Dose documentation includes the frequency, intensity, time, and type of interventions delivered (FITT Epic® Flowsheet) at each session.

DESIGN

Prospective time-series quality improvement study.

SETTING

Two large urban pediatric hospitals.

PARTICIPANTS

Occupational and physical therapy staff members.

INTERVENTION

Staff training and feedback loops utilizing existing groups.

OUTCOMES AND MEASURES

The process measure (number of available staff trained and using the FITT Epic Flowsheet over time) and the outcome measure (percentage of FITT Epic Flowsheets used for treatment visits each month) were analyzed using a statistical process control chart. The balancing measure (percentage of notes closed before 7 p.m. on the same day as the encounter) was analyzed using mean per month across three time periods.

RESULTS

Fifty-seven staff members (68%) attended formal training. On average, clinicians documented 90% of sessions using the FITT Epic Flowsheet after implementation. There was no change observed in the balancing measure.

CONCLUSIONS AND RELEVANCE

Documentation of dose was spread from one institution to another. Shared documentation will facilitate future collaboration for quality improvement and research purposes. Occupational therapy practitioners and leaders should consider implementing documentation with common dose elements. Plain-Language Summary: Occupational therapy documentation is often institution specific and may not adequately capture the dose of therapy (frequency, intensity, time) or types of interventions that were delivered, thus limiting opportunities for collaboration between institutions. This article adds to the literature on administrative supports for clinical and quality improvement research by illustrating a specific example of how documentation of dose can be shared from one institution to another. The data show that clinicians at one institution started using a new style of documentation using the FITT Epic® Flowsheet and shared discrete dose elements with another institution, creating new opportunities for collaboration. Shared documentation can facilitate future collaboration for quality improvement and research purposes.

Defining, quantifying, and reporting intensity, dose, and dosage of neurorehabilitative interventions focusing on motor outcomes

Introduction

Determining the minimal amount of therapy needed for positive neurorehabilitative outcomes is important for optimizing active treatment interventions to improve motor outcomes. However, there are various challenges when quantifying these relationships: first, several consensuses on the definition and usage of the terms intensity, dose, and dosage of motor interventions have been proposed, but there seems to be no agreement, and the terms are still used inconsistently. Second, randomized controlled trials frequently underreport items relevant to determining the intensity, dose, and dosage of the interventions. Third, there is no universal measure to quantify therapy intensity accurately. This "perspectives" paper aims to increase awareness of these topics among neurorehabilitation specialists.

Defining quantifying and reporting

We searched the literature for definitions of intensity, dose, and dosage and adapted the ones we considered the most appropriate to fit the needs of neurorehabilitative interventions. Furthermore, we suggest refining the template for intervention description and replication (TIDieR) to enhance the reporting of randomized controlled trials. Finally, we performed a systematic literature search to provide a list of intensity measures and complemented these with some novel candidate measures.

Discussion

The proposed definitions of intensity, dose, and dosage could improve the communication between neurorehabilitation specialists and the reporting of dose and dosage in interventional studies. Quantifying intensity is necessary to improve our understanding of the minimal intensity, dose, and dosage of therapy needed to improve motor outcomes in neurorehabilitation. We consider the lack of appropriate intensity measures a significant gap in knowledge requiring future research.

Clinical Outcomes of an Intensity Program for Children With Movement Challenges

PURPOSE

Physical therapists at an outpatient pediatric facility developed and implemented an Intensity Program for children with movement challenges. The program was initiated on the basis of best evidence, parent advocacy, and clinician expertise. The purpose of this investigation is to analyze outcome data gathered from the program since 2012 to determine the effect of the program along with any specific child characteristics that were more likely to lead to positive outcomes.

METHODS

A variety of outcome data were analyzed to compare preprogram performance with postprogram performance.

RESULTS

Program participants made statistically significant and clinically important improvement in most outcome measures. Parents were highly satisfied with the program, including 98% of respondents who indicated that they would like to repeat their participation in the program.

CONCLUSIONS

The results of this investigation suggest that many children with movement challenges are likely to benefit from participation in an Intensity Program.

Inpatient Physical Therapy After Orthopedic Lower Extremity Surgery in Children With Cerebral Palsy

PURPOSE

To characterize and examine the variability in receipt of inpatient (IP) physical therapy after lower extremity (LE) orthopedic surgery for individuals with cerebral palsy (CP) across hospital-level (region, bed size) and individual characteristics (gender, age, race/ethnicity, insurance type, technology dependency, and surgical burden).

METHODS

We retrospectively analyzed physical therapy billing data of children with CP who had LE orthopedic surgery from October 1, 2015, through September 30, 2017, from the Pediatric Health Information Services (PHIS) database.

RESULTS

Seventy-five percent of individuals received IP physical therapy during the hospital stay. Individuals from the South and West and those who were technology dependent were less likely to receive IP therapy. Those at large hospitals, aged 11 to 14 years, and with a high surgical burden were more likely to receive therapy.

CONCLUSIONS

Results provide a starting point for future research on the discrepancies of acute physical therapy services in children diagnosed with CP. (Supplemental digital content video abstract available at: http://links.lww.com/PPT/A420).

Use of supported standing in males with Duchenne muscular dystrophy: Individual and family perspectives

PURPOSE

This study aimed to explore stander use in individuals with Duchenne Muscular Dystrophy (DMD).

METHODS

This mixed method research study employed a survey with categorical and open-ended questions related to stander use. Categorical responses were analyzed quantitatively. Qualitative analysis of open-ended responses was linked to the International Classification of Function. Qualitative and quantitative results were merged to derive meta-inferences.

RESULTS

Of 147 respondents, 28.6% (n = 42) reported stander use. Equipment used included sit-to-stand stander (n = 27), power standing feature in a wheelchair (n = 13), and unspecified equipment (n = 2). Economic services were the most common barrier to stander obtainment. Age of loss of ambulation (LOA) and age of start of stander use were positively correlated (r = 0.61, p < 0.0001, n = 36), with 59.5% initiating stander use after LOA. Twenty-nine respondents reported standing less than the recommended dose of 60-90 minutes at least five days a week, with frequency directionally less than five days per week (p = 0.06) and time significantly less than 60-90 minutes (p = 0.002). Respondents' total dose was significantly lower than the recommended 300 minutes (p = 0.02). Lack of time and presence of contractures contributed to decreased duration of use.

CONCLUSION

This study provides a greater understanding of stander use among individuals with DMD and can assist with decision making about stander use prior to complications of disease progression to promote optimal health despite reported barriers.

Locomotor learning in infants at high risk for cerebral palsy: A study protocol

Background

Physical disability in individuals with cerebral palsy (CP) creates lifelong mobility challenges and healthcare costs. Despite this, very little is known about how infants at high risk for CP learn to move and acquire early locomotor skills, which set the foundation for lifelong mobility. The objective of this project is to characterize the evolution of locomotor learning over the first 18 months of life in infants at high risk for CP. To characterize how locomotor skill is learned, we will use robotic and sensor technology to provide intervention and longitudinally study infant movement across three stages of the development of human motor control: early spontaneous movement, prone locomotion (crawling), and upright locomotion (walking).

Study design

This longitudinal observational/intervention cohort study (ClinicalTrials.gov Identifier: NCT04561232) will enroll sixty participants who are at risk for CP due to a brain injury by one month post-term age. Study participation will be completed by 18 months of age. Early spontaneous leg movements will be measured monthly from 1 to 4 months of age using inertial sensors worn on the ankles for two full days each month. Infants who remain at high risk for CP at 4 months of age, as determined from clinical assessments of motor function and movement quality, will continue through two locomotor training phases. Prone locomotor training will be delivered from 5 to 9 months of age using a robotic crawl training device that responds to infant behavior in real-time. Upright locomotor training will be delivered from 9 to 18 months of age using a dynamic weight support system to allow participants to practice skills beyond their current level of function. Repeated assessments of locomotor skill, training characteristics (such as movement error, variability, movement time and postural control), and variables that may mediate locomotor learning will be collected every two months during prone training and every three months during upright training.

Discussion

This study will develop predictive models of locomotor skill acquisition over time. We hypothesize that experiencing and correcting movement errors is critical to skill acquisition in infants at risk for CP and that locomotor learning is mediated by neurobehavioral factors outside of training.Project Number 1R01HD098364-01A1.ClinicalTrials.gov Identifier: NCT04561232.

Research Summit V: Optimizing Transitions From Infancy to Early Adulthood in Children With Neuromotor Conditions

PURPOSE

The purpose of this executive summary is to review the process and outcomes of the Academy of Pediatric Physical Therapy Research Summit V, "Optimizing transitions from infancy to young adulthood in children with neuromotor disabilities: biological and environmental factors to support functional independence."

SUMMARY OF KEY POINTS

An interdisciplinary group of researchers, representatives from funding agencies, and individuals with neuromotor disabilities and their parents participated in an intensive 2.5-day summit to determine research priorities to optimize life transitions for children with neuromotor disabilities. Recommended priorities for research included (1) promoting self-determination and self-efficacy of individuals with neuromotor disabilities and their families, (2) best care at the right time: evidence-based best practice care, led and navigated by families seamlessly across the lifespan, (3) strengthening connections between developmental domains to enhance function and participation, and (4) optimal dosing and timing to support adaptive bone, muscle, and brain plasticity across the lifespan.

Effect of Contingency Paradigm-Based Interventions on Developmental Outcomes in Young Infants: A Systematic Review

PURPOSE

The purpose of this systematic review was to identify controlled trials evaluating the efficacy of contingency paradigm-based interventions to improve feeding, motor, or cognitive outcomes during the first year of life.

SUMMARY OF KEY POINTS

Seventeen studies, including 10 randomized controlled trials, incorporating contingency paradigm-based interventions were identified. Three of 3 trials reported improvements in nutritive sucking using pacifier-activated lullaby in preterm infants before term age. Seven of 12 trials reported improvements in reaching, manual exploration, and kicking behaviors in term and preterm infants; and 6 of 10 trials reported gains in early cognition using sticky mittens and contingent toys.

CONCLUSION AND RECOMMENDATIONS FOR CLINICAL PRACTICE

Contingency paradigm-based interventions can improve feeding outcomes in the neonatal intensive care unit in very preterm infants, and increase reaching, and perceptual-cognitive behaviors in term infants. Future research is needed to establish contingency paradigms as an effective early intervention strategy.

WHAT THIS ADDS TO THE EVIDENCE

This review synthesizes a body of literature on contingency paradigm-based interventions and highlights its potential paradigm-based interventions to improve developmental outcomes in infants.

Regional Differences in School-Based Physical Therapy Practice for Students Who Made Progress on 2 Outcome Measures

PURPOSE

This study examined whether regional differences exist in the provision of school-based physical therapy services for students who achieved positive progress and explored relationships between student outcomes and school-based physical therapy.

METHODS

Physical therapists developed student goals using Goal Attainment Scaling (GAS) and administered the School Function Assessment (SFA). Therapists documented activities, interventions, and type of service delivery provided weekly. Students were assigned to regions for analysis.

RESULTS

Student GAS goal attainment and progress on the SFA did not vary significantly among regions. The dosage of school-based physical therapy services, interventions, and activities varied.

CONCLUSIONS

There were regional differences that did not impact goal achievement. Further research is needed to identify the most efficient and effective interventions and dosage to support student outcomes.

Physical rehabilitation interventions in children with acquired brain injury: a scoping review

AIM

To synthesize the evidence about the characteristics (frequency, intensity, time, type) and effects of physical rehabilitation interventions on functional recovery and performance in daily functioning in children and young people with acquired brain injury (ABI), including traumatic brain injuries (TBI) and non-TBI, during the subacute rehabilitation phase.

METHOD

Using scoping review methodology, a systematic literature search was performed using four databases. Articles were screened by title and abstract and data from eligible studies were extracted for synthesis.

RESULTS

Nine of 3009 studies were included. The results demonstrated a variety of intervention characteristics: frequency varied between 1 and 7 days per week; time of intervention varied between 25 minutes and 6 hours a day; intervention types were specified in seven studies; and none of the included studies reported details of intensity of intervention. All studies reported positive results on the International Classification of Functioning, Disability and Health: Children and Youth (ICF-CY) levels of body function and activities after the intervention period, with study designs of included studies being cohort studies without concurrent controls (n=7) or case reports (n=2).

INTERPRETATION

Inconsistency in results hampers generalizability to guide clinical practice. Physical interventions during subacute rehabilitation have potential to improve functional recovery with intervention characteristics as an important factor influencing its effectiveness. Future well-designed studies are indicated to gain knowledge and optimize rehabilitation practice in paediatric ABI and high-quality research including outcomes across all ICF-CY domains is needed.

Early intervention evidence for infants with or at risk for cerebral palsy: an overview of systematic reviews

AIM

To perform an overview of systematic reviews and more recent randomized controlled trials (RCTs) on early motor interventions in infants aged 0 to 3 years with or at risk of cerebral palsy to inform current clinical and research efforts and provide a benchmark to assess future interventions ideally initiated within the first 6 months.

METHOD

Standardized searches of the PubMed, Embase, Scopus, and Web of Science databases were conducted for systematic reviews (2009-2020) and RCTs (2015-2020).

RESULTS

From 840 unique records, 31 full texts were reviewed, yielding three systematic reviews encompassing 46 studies, 16 with comparison groups, and six additional RCTs that met the criteria. Two enrichment- and activity-based approaches had medium effect sizes on motor development, only one with low risk of bias; two others had large task-specific effect sizes but some bias concerns; and three enriched environment studies with some bias concerns had medium effect sizes on cognitive development. Most had small or no effect sizes, bias concerns, and uncertain diagnostic determinations.

INTERPRETATION

Data synthesis revealed limited data quantity and quality, and suggest, although not yet confirmed, greater benefit from early versus later intervention. Research efforts with greater early diagnostic precision and earlier intervention are accelerating, which may transform future outcomes and practices. What this paper adds For over 50% of trials within the reviews, the intervention was compared to standard care with only two showing efficacy. Similar to results in older children, constraint-induced movement therapy (CIMT) emerged as efficacious with high effect sizes. CIMT was not superior to similarly intense bimanual training or occupational therapy. Goals-Activity-Motor Enrichment intervention initiated before 5 months of age was superior to equally intense standard care. Several other enriched environment strategies promoted cognitive and/or motor development.

Describing the Delivery of Evidence-Based Physical Therapy Intervention to Individuals With Cerebral Palsy

PURPOSE

To characterize by evidence grades and examine variation in type of physical therapy intervention delivered in routine clinical care in individuals with cerebral palsy (CP).

METHODS

Retrospective data collection from the electronic record over 1 year at a tertiary care pediatric outpatient therapy division.

RESULTS

Four hundred sixty-five individuals with CP received 28 344 interventions during 4335 treatment visits. Sixty-six percent of interventions were evidence-based interventions (EBIs). Significant variation was demonstrated across Gross Motor Function Classification System levels, with children classified as level V receiving the least and level III the most. The most frequent EBIs delivered were caregiver education, motor control, functional strengthening, ankle-foot orthoses, treadmill training, and fit of adaptive equipment.

CONCLUSIONS

Further work is needed to determine whether amount of EBI is related to better outcomes. Combining this information with other aspects of dose (intensity, time, and frequency) may elucidate the contribution of each with outcomes.

Combined clinic and home-based therapeutic approach for the treatment of bilateral radial deficiency for a young child with Holt-Oram syndrome: A case report

BACKGROUND

Holt-Oram syndrome (HOS) is a rare, genetic condition characterized by the combination of congenital heart defect and hypoplasia in one or both upper extremities. Children with HOS commonly present with varied joint and limb involvement including radial longitudinal deficiency impacting hand function. Evidence-based guidelines regarding orthotic wear and therapeutic techniques are lacking.

PURPOSE

The aim of this case report was to present the results of a long-term occupational therapy program for a patient with HOS pre and postpollicization.

STUDY DESIGN

Case report.

METHODS

A 4-month-old patient with bilateral radial longitudinal deficiencies began outpatient occupational therapy for custom orthosis fabrication and treatment which included long term clinic and home-based intervention. Techniques included passive range of motion, orthosis wear, therapeutic taping, and modified constraint induced movement therapy. Longitudinal assessment of musculoskeletal alignment and functional hand use was performed using goniometry for passive and active range of motion, the Assisting Hand Assessment (AHA), and The Thumb Grasp and Pinch Assessment (T-GAP).

RESULTS

Improvement in passive and active range of motion was achieved as well as improved activity level function as measured by the AHA and T-GAP postpollicization and intervention.

CONCLUSIONS

A combined clinic and home-based therapeutic approach can be effective for children with HOS to improve alignment and function pre and postpollicization to further enhance hand function. Comprehensive, long-term assessment is necessary to fully evaluate and communicate improvement.

Group-based constraint-induced movement therapy in the rehabilitation of chronic poststroke patients

BACKGROUND

This study aimed to describe the effects of a 90-minute group-based constraint-induced movement therapy protocol (CIMT) on upper extremity (UE) rehabilitation in poststroke patients.

METHOD

The study was a case series clinical study with 6 patients with chronic stroke admitted to the institutional integrated clinic. Ten 90-minute CIMT sessions were administered, based on the principles of the original therapy. On completion of the protocol, participants underwent group care once a week, for 1 hour a day. For comparison purposes, the Wolf Motor Function Test (WMFT), Motor Activity Log (MAL), and Canadian Occupational Performance Measure (COPM) were applied on admission, shortly after completing the protocol, and 3 months after completion. In addition, the MAL and shaping tasks were applied daily.

RESULTS

There was a statistically significant difference only in the MAL Amount of Use Scale applied daily between the 2nd (3.56) and 9th (3.31) and 2nd and 10th days (4.49) (P = .004), with a moderate effect size (d' = 0.46), and in the average value of shaping repetitions between the 1st (16.10) and 2nd (6.00) and 1st and 10th tasks (7.00) (P = .014), with a moderate effect size (d' = 0.35).

CONCLUSION

The 90-minute CIMT protocol resulted in significant improvements in use of the more affected arm in activities of daily living during the 2-week protocol. Additional research with a larger sample and a control group is needed to confirm its effectiveness.

How does the intensity of physical therapy affect the Gross Motor Function Measure (GMFM-66) total score in children with cerebral palsy? A systematic review protocol

INTRODUCTION

Intensive physical therapy (PT) interventions administered to children with cerebral palsy (CP) have received a significant amount of attention in published literature. However, there is considerable variability in therapy intensity among studies and notable lack of information on optimal intervention dosing. This makes it difficult for clinicians to use evidence to inform practice. Many studies use the Gross Motor Function Measure (GMFM-66) to assess functional progress in children with CP. The purpose of this systematic review will be to identify the GMFM-66 change score reported in published studies, with outcomes based on intervention intensity. Whether the type of PT intervention, child's age, and Gross Motor Function Classification System level influence the GMFM-66 scores will be also assessed.

METHODS AND ANALYSIS

This systematic review protocol was developed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) 2015 checklist. In March 2018, nine databases (PubMed, Ovid MEDLINE, Cochrane Library, Embase, Scopus, Web of Science, CINAHL, ClinicalTrials.gov, and REHABDATA) were searched for controlled clinical trials and single-subject design studies of PT interventions of any kind and intensity that used the GMFM-66 as an outcome measure for children with CP, age up to 18 years. Two authors independently reviewed the titles and abstracts and arrived at consensus on paper selection for a full-text review. The same process was used for a full-text article screening based on further detailed inclusion criteria, with a final selection made for those suitable for data extraction. Prior to commencement of data extraction, all searches will be updated, and new results re-screened.

ETHICS AND DISSEMINATION

This study will involve a systematic review of published articles and no primary data collection. Therefore, no ethical approval will be necessary. Results will be disseminated in a peer-reviewed publication and presented at scientific conferences.

Methodological Considerations to Investigate Dosage Parameters of Intensive Upper Limb Rehabilitation in Children with Unilateral Spastic Cerebral Palsy: A Scoping Review of RCTs

PURPOSES

To identify and synthesize RCTs on the isolated effect of dosage parameters of upper limb Intensive Motor Rehabilitation Treatments (IMRT) of children with Unilateral Spastic Cerebral Palsy (USCP); to identify the most frequent methodological weaknesses.

METHODS

Searches were conducted until September 2018 in gray and published literature databases and supplemented by exploring the identified studies' references. Inclusion criteria applied: RCT; children aged 1.5 to 19 years with USCP; upper limb IMRT differing only from ≥1/4 dosage parameters between groups. Literature analyses conducted: qualitative and descriptive.

RESULTS

We identified 461 studies. Seventeen were included: three presented a rehabilitation dosage distinction between groups in Frequency-Time, four in Intensity-Progressivity, three in Intensity-Restraint, two in Intensity-Environment and five presented ≥3 distinctions above.

CONCLUSIONS

Inconsistencies were noted between USCP lifelong issues, and the short follow-ups and lack of participation assessments. Confounding factors and misstatements in Intent To Treat (ITT) analyses were identified. A meta-analysis was considered irrelevant.

ABBREVIATIONS

Cerebral Palsy Research Network Clinical Registry: Methodology and Baseline Report

Objective

To apply practice-based evidence to clinical management of cerebral palsy (CP). The process of establishing purpose, structure, logistics, and elements of a multi-institutional registry and the baseline characteristics of initial enrollees are reported.

Design

A consensus-building process among consumers, clinicians, and researchers used a participatory action process.

Setting

Community, hospitals, and universities.

Participants

More than 100 clinicians, researchers, and consumers and more than 1858 enrollees in the registry.

Main Outcome Measures

Not applicable.

Results

Consensus was that the purpose of registry was to (1) quantify practice variation, (2) facilitate quality improvement (QI), and (3) perform comparative effectiveness research (CER). Collecting data during routine clinical care using the electronic medical record was determined to be a sustainable plan for data acquisition and management. Clinicians from multiple disciplines defined salient characteristics of individuals and interventions for the registry elements. The registry was central to the clinical research network, and a leadership structure was created. A leading electronic health record platform adopted the registry elements. Twenty-four sites have initiated the data collection process and agreed to export data to the registry. Currently 12 are collecting data. Number of enrollees and characteristics were similar to other population registers.

Conclusions

This is the first multi-institutional CP registry that contains the patient and treatment characteristics needed for QI and CER. The Cerebral Palsy Research Network registry elements are implemented in a versatile electronic platform and minimize burden to clinicians. The resultant registry is available for any institution to participate and is growing rapidly.

Documenting Physical Therapy Dose for Individuals With Cerebral Palsy: A Quality Improvement Initiative

PURPOSE

To describe the quality improvement (QI) activities used to improve treatment dose documentation for individuals with cerebral palsy (CP) and to discuss insights gained from this project.

METHODS

Global and smart aims were established and interventions were tested from January 2017 through February 2018 using Plan-Do-Study-Act cycles. Performance was tracked overtime using run and control charts.

RESULTS

The QI initiative resulted in a sustainable increase in percentage of dose elements present in the electronic medical record from 78% to 94%. Key drivers of improvement included (1) knowledge and awareness of dose, (2) clinician buy-in, (3) effective engagement of child and parent, (4) therapist knowledge of evidence-based treatments, (5) transparent and reliable documentation system, and (6) audit and clinician feedback.

CONCLUSIONS

QI methods provided the tools to improve workflow and increase dose documentation for individuals with CP.

Daily and Weekly Rehabilitation Delivery for Young Children With Gross Motor Delay: A Randomized Clinical Trial Protocol (the DRIVE Study)

PURPOSE

The proposed project tests the principle that frequency of rehabilitation is an important regulator of therapeutic response in infants.

METHODS

We will randomize 75 infants with cerebral palsy, 6 to 24 months of age and/or Gross Motor Function Classification System levels III to V (higher severity), to determine the short-term and long-term effects of 3 dosing protocols consisting of an identical number of 2-hour sessions of the same motor learning-based therapy applied over a different total number of calendar weeks.

RESULTS AND CONCLUSIONS

The results will inform clinicians, families, and scientists about dosing and will provide needed recommendations for frequency of rehabilitation to optimize motor function and development of young children with cerebral palsy.

Feasibility of an intensive outpatient Perception-Action Approach intervention for children with cerebral palsy: a pilot study

PURPOSE

The purpose of this pilot study was (1) to evaluate feasibility of attendance and parent satisfaction with an intensive outpatient physical and occupational therapy program for young children with spastic cerebral palsy (CP) and (2) to examine changes in motor function. Methods: Sixteen children with CP, age range 18-36 months (mean 24.3 ± 6.3 months), received physical and occupational therapy sessions (30 minutes each) 5 days per week for 12 weeks. Attendance rates and parent satisfaction were assessed. Change in motor function using a one-group pre-post design was evaluated using the Gross Motor Function Measure-66 (GMFM-66), Quality of Upper Extremity Skills Test, and Pediatric Evaluation of Disability Inventory. GMFM-66 outcomes were also compared with expected outcomes using previously published normative developmental trajectories of children receiving standard therapies. Results: An average of 82% of scheduled outpatient physical and occupational therapies for 16 children were completed and the 11 parents who completed the Hills and Kitchen's Physiotherapy Outpatient Satisfaction Questionnaire were satisfied with the therapies and with their child's progress. Participants showed notable, statistically significant improvement across all activity-related measures. Conclusion: An intensive protocol of outpatient therapies utilizing Perception-Action Approach was feasible for most families of young children with spastic CP to attend at the outpatient clinic location. As this was not an experimental study, no reliable conclusions related to efficacy can be made, but the promising results suggest that further research into the effectiveness of intensive protocols is worthwhile.

Does Dosage Matter? A Pilot Study of Hand-Arm Bimanual Intensive Training (HABIT) Dose and Dosing Schedule in Children with Unilateral Cerebral Palsy

AIM

We compared the efficacy of hand-arm bimanual intensive training (HABIT) in two doses (90 vs. 45 hours) and two schedules of the same dose (90 vs. 2 × 45 hours) on hand and daily functioning.

METHOD

Eighteen children with unilateral cerebral palsy were randomized to receive 6 hours of daily training over 3 weeks, totaling 90 hours (Group 90, n = 9) or receive 6 hours of daily training over 1.5 weeks, totaling 45 hours (Group 2 × 45, n = 9). After 6 months, Group 2 × 45 received an additional 45 hours. Hand (Jebsen-Taylor Test of Hand Function, Assisting Hand Assessment) and daily functioning tests (Canadian Occupational Performance Measure, Pediatric Evaluation of Disability Inventory) were administered before, immediately after, and 6 months after interventions.

RESULTS

Both groups demonstrated significant improvements in hand and daily functioning after 90 hours (Group 90) or the first 45 hours (Group 2 × 45), without differences between groups. However, more children from Group 90 obtained smallest detectable differences in the Assisting Hand Assessment. The addition of the second bout of 45 hours (Group 2 × 45) did not lead to further improvements.

CONCLUSIONS

As this study was powered to test for large differences between groups, future investigations on larger samples will be needed to compare differences at the two dosage levels.

Exploring the parameters of intensity, frequency, and duration within the constraint induced movement therapy published research: A content analysis

BACKGROUND

Neurological rehabilitation specialists must determine appropriate dosage, consisting of frequency, intensity, and duration of specified treatments.

OBJECTIVE

The objective of this study was to perform a content analysis of the current literature related to dosage (duration, frequency and intensity) for constraint-induced movement therapy (CIMT) in the adult population.

METHODS

A content analysis was conducted which yielded 62 scholarly articles.

RESULTS

The frequency of CIMT ranged from 1 to 7 days per week with the average frequency being 4.98 days. The duration of CIMT, ranged from 2 to 10 weeks with the average duration 3.14 weeks. All three components of dosage were reported collectively in outcomes studies conducted in inpatient settings and rehabilitation clinics.

CONCLUSIONS

The findings provide a groundwork for evidence based practice for clinician in the application of CIMT dosage with consideration of settings and CIMT components.

The effects of dosage time and frequency on motor outcomes in children with cerebral palsy: A systematic review

PURPOSE

Provide an updated review regarding treatment dosage for children with cerebral palsy (CP) by examining the variables of type, time, frequency, and intensity.

METHODS

A systematic review was performed with 30 articles meeting the inclusion criteria. Two authors independently extracted data including information about risk of bias. Ten articles were included in the review.

RESULTS

Eight studies manipulated time, two studies manipulated frequency, and three studies manipulated both variables. No studies investigated intensity. Findings suggest that manipulating time and/or frequency may result in better motor function for higher total dosing; however, benefits were not consistent across studies and few showed clinically significant improvements.

CONCLUSION

This most current evidence regarding the effect of dosage on motor function for children with CP suggests that there is insufficient evidence to support implementing high-dosage therapy. Further research is needed to clarify the relationship between dosage variables on motor function for children with CP.

Treadmill interventions in children under six years of age at risk of neuromotor delay

BACKGROUND

Delayed motor development may occur in children with Down syndrome, cerebral palsy, general developmental delay or children born preterm. It limits the child's exploration of the environment and can hinder cognitive and social-emotional development. Literature suggests that task-specific training, such as locomotor treadmill training, facilitates motor development.

OBJECTIVES

To assess the effectiveness of treadmill interventions on locomotor development in children with delayed ambulation or in pre-ambulatory children (or both), who are under six years of age and who are at risk for neuromotor delay.

SEARCH METHODS

In May 2017, we searched CENTRAL, MEDLINE, Embase, six other databases and a number of trials registers. We also searched the reference lists of relevant studies and systematic reviews.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs that evaluated the effect of treadmill intervention in the target population.

DATA COLLECTION AND ANALYSIS

Four authors independently extracted the data. Outcome parameters were structured according to the International Classification of Functioning, Disability and Health model.

MAIN RESULTS

This is an update of a Cochrane review from 2011, which included five trials. This update includes seven studies on treadmill intervention in 175 children: 104 were allocated to treadmill groups, and 71 were controls. The studies varied in population (children with Down syndrome, cerebral palsy, developmental delay or at moderate risk for neuromotor delay); comparison type (treadmill versus no treadmill; treadmill with versus without orthoses; high- versus low-intensity training); study duration, and assessed outcomes. Due to the diversity of the studies, only data from five studies were used in meta-analyses for five outcomes: age of independent walking onset, overall gross motor function, gross motor function related to standing and walking, and gait velocity. GRADE assessments of quality of the evidence ranged from high to very low.The effects of treadmill intervention on independent walking onset compared to no treadmill intervention was population dependent, but showed no overall effect (mean difference (MD) -2.08, 95% confidence intervals (CI) -5.38 to 1.22, 2 studies, 58 children; moderate-quality evidence): 30 children with Down syndrome benefited from treadmill training (MD -4.00, 95% CI -6.96 to -1.04), but 28 children at moderate risk of developmental delay did not (MD -0.60, 95% CI -2.34 to 1.14). We found no evidence regarding walking onset in two studies that compared treadmill intervention with and without orthotics in 17 children (MD 0.10, 95% CI -5.96 to 6.16), and high- versus low-intensity treadmill interventions in 30 children with Down syndrome (MD -2.13, 95% -4.96 to 0.70).Treadmill intervention did not improve overall gross motor function (MD 0.88, 95% CI -4.54 to 6.30, 2 studies, 36 children; moderate-quality evidence) or gross motor skills related to standing (MD 5.41, 95% CI -1.64 to 12.43, 2 studies, 32 children; low-quality evidence), and had a negligible improvement in gross motor skills related to walking (MD 4.51, 95% CI 0.29 to 8.73, 2 studies, 32 children; low-quality evidence). It led to improved walking skills in 20 ambulatory children with developmental delay (MD 7.60, 95% CI 0.88 to 14.32, 1 study) and favourable gross motor skills in 12 children with cerebral palsy (MD 8.00, 95% CI 3.18 to 12.82). A study which compared treadmill intervention with and without orthotics in 17 children with Down syndrome suggested that adding orthotics might hinder overall gross motor progress (MD -8.40, 95% CI -14.55 to -2.25).Overall, treadmill intervention showed a very small increase in walking speed compared to no treadmill intervention (MD 0.23, 95% CI 0.08 to 0.37, 2 studies, 32 children; high-quality evidence). Treadmill intervention increased walking speed in 20 ambulatory children with developmental delay (MD 0.25, 95% CI 0.08 to 0.42), but not in 12 children with cerebral palsy (MD 0.18, 95% CI -0.09 to 0.45).

AUTHORS' CONCLUSIONS

This update of the review from 2011 provides additional evidence of the efficacy of treadmill intervention for certain groups of children up to six years of age, but power to find significant results still remains limited. The current findings indicate that treadmill intervention may accelerate the development of independent walking in children with Down syndrome and may accelerate motor skill attainment in children with cerebral palsy and general developmental delay. Future research should first confirm these findings with larger and better designed studies, especially for infants with cerebral palsy and developmental delay. Once efficacy is established, research should examine the optimal dosage of treadmill intervention in these populations.

Coupling Timing of Interventions With Dose to Optimize Plasticity and Participation in Pediatric Neurologic Populations

PURPOSE

The purpose of this article is to propose that coupling of timing of interventions with dosing of interventions optimizes plasticity and participation in pediatric neurologic conditions, specifically cerebral palsy. Dosing includes frequency, intensity, time per session, and type of intervention. Interventions focus on body structures and function and activity and participation, and both are explored. Known parameters for promoting bone, muscle, and brain plasticity and evidence supporting critical periods of growth during development are reviewed. Although parameters for dosing participation are not yet established, emerging evidence suggests that participation at high intensities has the potential for change. Participation interventions may provide an additional avenue to promote change through the life span. Recommendations for research and clinical practice are presented to stimulate discussions and innovations in research and practice.

Effect of early intervention in infants at very high risk of cerebral palsy: a systematic review

AIM

First, to systematically review the evidence on the effect of intervention applied during the first postnatal year in infants with or at very high risk of cerebral palsy (CP) on child and family outcome. Second, to assess whether type and dosing of intervention modify the effect of intervention.

METHOD

Relevant literature was identified by searching the PubMed, Embase, and CINAHL databases. Selection criteria included infants younger than 12 months corrected age with or at very high risk of CP. Methodological quality including risk of bias was scrutinized.

RESULTS

Thirteen papers met the inclusion criteria. Seven studies with moderate to high methodological quality were analysed in detail; they evaluated neurodevelopmental treatment only (n=2), multisensory stimulation (n=1), developmental stimulation (n=2), and multifaceted interventions consisting of a mix of developmental stimulation, support of parent-infant interaction, and neurodevelopmental treatment (n=2). The heterogeneity precluded conclusions. Yet, two suggestions emerged: (1) dosing may be critical for effectiveness; (2) multifaceted intervention may offer best opportunities for child and family.

INTERPRETATION

The literature on early intervention in very high-risk infants with sufficient methodological quality is limited, heterogeneous, and provides weak evidence on the effect. More studies are urgently needed. Suggestions for future research are provided.

Standing activity intervention and motor function in a young child with cerebral palsy: A case report

PURPOSE

There is limited evidence to fully justify the use of standing interventions for children with cerebral palsy (CP). This case report describes the impact of an 8-week standing program on motor function in a child with severe CP living in western Africa.

METHODS

The subject was diagnosed with ischemic - hypoxic encephalopathy shortly after birth and with CP at 12 months of age. Gross Motor Function Classification of CP was level IV. Early attempts at physical therapy were interrupted by limited access to medical services. At 18 months, a standing program using a locally constructed standing frame was initiated. The standing intervention was completed at home 5 times a week for 8 weeks. Motor skills were assessed at baseline and post-intervention using the Gross Motor Function Measure (GMFM-66).

RESULTS

Scores on the GMFM-66 increased from 28 at baseline to 37.4 in 8 weeks. Improvements in motor function included improved head control, improved upper extremity function, and increased sitting ability.

CONCLUSIONS

Implementation of a home-based standing program may have contributed to improved motor skills for this child. Further research is needed to determine the effect of standing interventions on functional motor development for children with severe CP.

Exploring the feasibility and use of accelerometers before, during, and after a camp-based CIMT program for children with cerebral palsy

PURPOSE

The aim of this pilot study was to determine the feasibility and use accelerometers before, during, and after a camp-based constraint-induced movement therapy (CIMT) program for children with hemiplegic cerebral palsy.

METHODS

A pre-test post-test design was used for 12 children with CP (mean = 4.9 yrs) who completed a 30-hour camp-based CIMT program. The accelerometer data were collected using ActiGraph GT9X Link. Children wore accelerometers on both wrists one day before and after the camp and on the affected limb during each camp day. Three developmental assessments were administered pre-post CIMT program.

RESULTS

Accelerometers were successfully worn before, during, and directly after the CIMT program to collect upper limb data. Affected upper limb accelerometer activity significantly increased during the CIMT camp compared to baseline (p< 0.05). Significant improvements were seen in all twelve children on all assessments of affected upper limb function (p< 0.05) measuring capacity and quality of affected upper limb functioning.

CONCLUSION

Accelerometers can be worn during high intensity pediatric CIMT programs to collect data about affected upper limb function. Further study is required to determine the relationship between accelerometer data, measure of motor capacity, and real-world performance post-CIMT.

Implementation of the Hammersmith Infant Neurological Examination in a High-Risk Infant Follow-Up Program

BACKGROUND

High-risk infant follow-up programs provide early identification and referral for treatment of neurodevelopmental delays and impairments. In these programs, a standardized neurological examination is a critical component of evaluation for clinical and research purposes.

METHODS

To address primary challenges of provider educational diversity and standardized documentation, we designed an approach to training and implementation of the Hammersmith Infant Neurological Examination with precourse materials, a workshop model, and adaptation of the electronic medical record.

CONCLUSIONS

Provider completion and documentation of a neurological examination were evaluated before and after Hammersmith Infant Neurological Examination training. Standardized training and implementation of the Hammersmith Infant Neurological Examination in a large high-risk infant follow-up is feasible and effective and allows for quantitative evaluation of neurological findings and developmental trajectories.

Dosage Parameters in Pediatric Outcome Studies Reported in 9 Peer-Reviewed Occupational Therapy Journals from 2008 to 2014: A Content Analysis

Occupational therapists determine the dosage when establishing the plan of care for their pediatric clients. A content analysis was conducted using 123 pediatric occupational therapy outcomes studies from 9 scholarly international occupational therapy journals. The parameters of dosage were calculated using descriptive statistics in order to obtain a representation of dosage available within the current collage of pediatric occupational therapy outcomes studies. The results revealed that most studies reported portions of dosage parameters within the published studies. The average findings for the subcomponents related to dosage were session length (minutes) M = 58.7, duration of plan of care (weeks) M = 12.1, session frequency (per week) M = 3.4, and total hours of therapy (hours) M = 18.1. This first attempt at describing and calculating dosage related to pediatric occupational therapy practice indicates that evidence is lacking within the published literature to adequately guide OT dosage decisions. Further research related to dosage in pediatric occupational therapy practice is needed.

Effects of a Group-Based Treadmill Program on Children With Neurodevelopmental Impairment Who Are Not Yet Ambulating

PURPOSE

To examine the effects of a group-based treadmill program on gross motor skills related to walking and the amount of support needed for ambulation in children with neuromotor impairment who are not yet walking.

METHODS

Twelve children (mean age, 30.4 months; standard deviation, 7.9) participated in the program twice per week for 14 weeks. The Gross Motor Function Measure-88 Dimensions D and E (GMFM-88 D/E), the Functional Mobility Scale (FMS), the timed 10-m walk test, and the Pediatric Evaluation of Disability Inventory Mobility Scale (PEDI) were administered before and at the conclusion of the program. Data were analyzed using paired the t test and Wilcoxon matched-pairs signed rank test.

RESULTS

Statistically significant improvements were found between pre- and posttests in the GMFM-88 D (P = .0005) and E (P = .001), in FMS scores (P = .039), and the PEDI (P = .001).

CONCLUSIONS

A group-based treadmill program leads to positive changes in walking ability in children with neuromotor impairment.

Comparative Effectiveness Research and Children With Cerebral Palsy: Identifying a Conceptual Framework and Specifying Measures

PURPOSE

A step toward advancing research about rehabilitation service associated with positive outcomes for children with cerebral palsy is consensus about a conceptual framework and measures.

METHODS

A Delphi process was used to establish consensus among clinicians and researchers in North America.

RESULTS

Directors of large pediatric rehabilitation centers, clinicians from large hospitals, and researchers with expertise in outcomes participated (N = 18). Andersen's model of health care utilization framed outcomes: consumer satisfaction, activity, participation, quality of life, and pain. Measures agreed upon included Participation and Environment Measure for Children and Youth, Measure of Processes of Care, PEDI-CAT, KIDSCREEN-10, PROMIS Pediatric Pain Interference Scale, Visual Analog Scale for pain intensity, PROMIS Global Health Short Form, Family Environment Scale, Family Support Scale, and functional classification levels for gross motor, manual ability, and communication.

CONCLUSIONS

Universal forms for documenting service use are needed. Findings inform clinicians and researchers concerned with outcome assessment.

Technology for Children With Brain Injury and Motor Disability: Executive Summary From Research Summit IV

Advances in technology show promise as tools to optimize functional mobility, independence, and participation in infants and children with motor disability due to brain injury. Although technologies are often used in adult rehabilitation, these have not been widely applied to rehabilitation of infants and children. In October 2015, the Academy of Pediatric Physical Therapy sponsored Research Summit IV, "Innovations in Technology for Children With Brain Insults: Maximizing Outcomes." The summit included pediatric physical therapist researchers, experts from other scientific fields, funding agencies, and consumers. Participants identified challenges in implementing technology in pediatric rehabilitation including accessibility, affordability, managing large data sets, and identifying relevant data elements. Participants identified 4 key areas for technology development: to determine (1) thresholds for learning, (2) appropriate transfer to independence, (3) optimal measurement of subtle changes, and (4) how to adapt to growth and changing abilities.

Cognitive rehabilitation in a child with Joubert Syndrome: Developmental trends and adaptive changes in a single case report

We report the clinical and rehabilitative follow up of M, a female child carrying a compound heterozygous pathogenic mutations in the TCTN1 gene and affected by Joubert Syndrome (JS). JS is a congenital cerebellar ataxia characterized by "the molar tooth sign" on axial MRI, a pathognomonic neuroradiological malformation involving the cerebellum and brainstem. JS presents with high phenotypic/cognitive variability, and little is known about cognitive rehabilitation programs. We describe the therapeutic settings, intensive rehabilitation targets and outcome indexes in M's cognitive development. Using a single case evidence-based approach, we attempt to distinguish the effectiveness of the intervention from the overall developmental trend. We assume that an adequate amount of focused, goal directed treatment in a relative short period of time can be at least as effective as one provided in longer time, and much less interfering with the child's everyday life. We conclude by discussing specific issues in cognitive development and rehabilitation in JS and, more broadly, in cerebellar malformations.

Implementing treatment frequency and duration guidelines in a hospital-based pediatric outpatient setting: administrative case report

BACKGROUND AND PURPOSE

Determining treatment frequency and duration of physical therapist services is an important component of outpatient pediatric physical therapist practice, yet there is little research available to inform these decisions. Treatment frequency guidelines (TFG) can assist decision making in guiding pediatric physical therapy. The purpose of this project was to examine the feasibility and application of implementing TFG in hospital-based pediatric outpatient physical therapy.

PROJECT DESCRIPTION

Previously developed TFG were modified for use in our pediatric outpatient physical therapy department to include duration and were referred to as treatment frequency and duration guidelines (TFDG). In order to successfully implement the TFDG, there were 2 phases to the project. In phase 1, the staff were provided the guidelines and procedures in a staff meeting and via email using a PowerPoint presentation. Phase 2 was initiated due to the poor response of the staff in implementing the guidelines in their practice after phase 1. The format was changed to include formal re-education via small-group and one-on-one education sessions (phase 2). Chart reviews were completed to assess therapists' adherence to using TFDG.

OUTCOMES

Therapists' adherence to use of TFDG increased following re-education: phase 1 (n=225 charts, 31% adherence) and phase 2 (n=197 charts, 90% adherence).

DISCUSSION

Treatment frequency and duration guidelines may assist in guiding frequency and duration decisions in pediatric physical therapy. Education via in-person meetings may improve adherence among staff.

Early intervention to improve hand function in hemiplegic cerebral palsy

Children with hemiplegic cerebral palsy often have marked hand involvement with excessive thumb adduction and flexion and limited active wrist extension from infancy. Post-lesional aberrant plasticity can lead to progressive abnormalities of the developing motor system. Disturbances of somatosensory and visual function and developmental disregard contribute to difficulties with hand use. Progressive soft tissue and bony changes may occur, leading to contractures, which further limit function in a vicious cycle. Early intervention might help to break this cycle, however, the precise nature and appropriateness of the intervention must be carefully considered. Traditional approaches to the hemiplegic upper limb include medications and botulinum toxin injections to manage abnormalities of tone, and surgical interventions. Therapist input, including provision of orthoses, remains a mainstay although many therapies have not been well evaluated. There has been a recent increase in interventions for the hemiplegic upper limb, mostly aimed outside the period of infancy. These include trials of constraint-induced movement therapy (CIMT) and bimanual therapy as well as the use of virtual reality and robot-assisted therapy. In future, non-invasive brain stimulation may be combined with therapy. Interventions under investigation in the infant age group include modified CIMT and action observation therapy. A further approach which may be suited to the infant with thumb-in-palm deformity, but which requires evaluation, is the use of elastic taping. Enhanced cutaneous feedback through mechanical stimulation to the skin provided by the tape during movement has been postulated to modulate ongoing muscle activity. If effective, this would represent a low-cost, safe, widely applicable early intervention.

The scope of pediatric physical therapy practice in health promotion and fitness for youth with disabilities

PURPOSE

The purpose of this report is to discuss the scope of pediatric physical therapy practice in health promotion and fitness for youth with disabilities.

SUMMARY OF KEY POINTS

Evidence is provided that supports integration of health promotion and fitness strategies in physical therapy clinical management. Physical therapists' roles in community-based adapted sports and fitness interventions and reimbursement considerations are discussed.

CONCLUSIONS

Physical therapists are in a unique position to provide expertise in the design and implementation of health promotion and fitness programs for youth with disabilities. These programs are important to promote active, healthy lifestyles and reduce comorbidities associated with sedentary behaviors and unhealthy weight, which are often seen in youth with disabilities.

RECOMMENDATIONS FOR CLINICAL PRACTICE

Pediatric physical therapists should incorporate health promotion and fitness strategies into practice.

Daily Intervention for Young Children With Cerebral Palsy in GMFCS Level V: A Case Series

PURPOSE

To describe a daily physical therapy (PT) intervention program and outcomes for 2 young children with spastic quadriplegia, Gross Motor Function Classification System (GMFCS) level V, and to evaluate the feasibility of using a daily program in an urban children's hospital outpatient setting.

SUMMARY OF KEY POINTS

Two young children, GMFCS level V, received 2 hours of PT intervention based on motor learning principles 5 days a week for 4 consecutive weeks. Gross Motor Functional Measure (GMFM-66, GMFM-88) and the Bayley Scales of Infant Development, Third Edition, were used as pre- and postoutcome measures. The daily, high intensity intervention was well tolerated. Improvements in motor function, language, and cognitive skills were found.

STATEMENT OF CONCLUSION

A daily PT program appears feasible and may improve overall development in young children with cerebral palsy in GMFCS level V.
