Exploring Physiotherapists' Use of Motor Learning Strategies in Gait-Based Interventions for Children with Cerebral Palsy

Physiotherapy-assisted overground exoskeleton use: mixed methods feasibility study protocol quantifying the user experience, as well as functional, neural, and muscular outcomes in children with mobility impairments

Background

Early phase research suggests that physiotherapy paired with use of robotic walking aids provides a novel opportunity for children with severe mobility challenges to experience active walking. The Trexo Plus is a pediatric lower limb exoskeleton mounted on a wheeled walker frame, and is adjustable to fit a child's positional and gait requirements. It guides and powers the child's leg movements in a way that is individualized to their movement potential and upright support needs, and can provide progressive challenges for walking within a physiotherapy-based motor learning treatment paradigm.

Methods

This protocol outlines a single group mixed-methods study that assesses the feasibility of physiotherapy-assisted overground Trexo use in school and outpatient settings during a 6-week physiotherapy block. Children ages 3-6 years (n = 10; cerebral palsy or related disorder, Gross Motor Function Classification System level IV) will be recruited by circle of care invitations to participate. Study indicators/outcomes will focus on evaluation of: (i) clinical feasibility, safety, and acceptability of intervention; (ii) pre-post intervention motor/functional outcomes; (iii) pre-post intervention brain structure characterization and resting state brain connectivity; (iv) muscle activity characterization during Trexo-assisted gait and natural assisted gait; (v) heart rate during Trexo-assisted gait and natural assisted gait; and (vi) user experience and perceptions of physiotherapists, children, and parents.

Discussion

This will be the first study to investigate feasibility indicators, outcomes, and experiences of Trexo-based physiotherapy in a school and outpatient context with children who have mobility challenges. It will explore the possibility of experience-dependent neuroplasticity in the context of gait rehabilitation, as well as associated functional and muscular outcomes. Finally, the study will address important questions about clinical utility and future adoption of the device from the physiotherapists' perspective, comfort and engagement from the children's perspective, and the impressions of parents about the value of introducing this technology as an early intervention.

Development of a Play-Based Motor Learning Approach (A.MO.GIOCO) in Children with Bilateral Cerebral Palsy: Theoretical Framework and Intervention Methodology

The early intervention of motor training based on specific tasks and parent empowerment represents the new paradigm for the rehabilitation of children with Cerebral Palsy (CP). However, most published studies address the problem of the effectiveness of rehabilitation intervention without describing the treatment methodology or briefly mentioning it. The purpose of the study is to illustrate the development of a play-based motor learning approach titled A.MO.GIOCO (Apprendimento MOtorio nel GIOCO) and its systematization. Fifteen children aged between 2 and 6 years with bilateral CP will be enrolled and treated for 6-8 weeks (48 h). Motor Teaching methods applied by senior therapists have been extensively described, starting from rehabilitation goals and proposed therapeutic play activities, tailored to the functional profile of each child. This child-friendly rehabilitative approach (A.MO.GIOCO) refers to the systemic cognitive model of learning and movement control and is implemented in the context of spontaneous play activities and in the therapist-child-family interaction. In this study the theoretical framework of the approach and the process followed by the therapists to transfer it into rehabilitative practice are highlighted. As a result, an operational guide has been created. Further studies will explore the efficacy of the proposed standardized approach.

Perceptions of learning and teaching human movement in physiotherapy: A systematic review and metasynthesis of qualitative studies

PURPOSE

Human movement is essential for health and well-being. Understanding human movement is pivotal in physiotherapy, but also an important element of physiotherapy education. This review identified, critically appraised, and synthesized the available evidence on learning and teaching human movement in physiotherapy as perceived by students, therapists, and instructors.

METHODS

The databases MEDLINE, CINAHL, ERIC, PsycINFO, MEDIC and FINNA, were searched. The search was conducted in March/April 2020 and updated in March 2022. The systematic review followed the JBI methodology for systematic reviews of qualitative evidence and was conducted in accordance with an a priori protocol.

RESULTS

The overall quality of the 17 included studies was scored low on ConQual but dependability and credibility were rated as moderate. Four synthesized findings aggregated from 17 categories and 147 findings described the perceived significance of 1) being present in movement, 2) movement quality, 3) movement transfer, and 4) contextual factors for the learning or teaching of human movement in physiotherapy.

CONCLUSION

The synthesized findings indicate that the perceived significance of contextual factors, movement quality and transfer, and being present in movement should be considered in all learning and teaching of movement in physiotherapy. However, the evidence of the review findings was evaluated as low-level, which should be considered when applying these results to physiotherapy education or practice.

Assessing the impact of a knowledge translation intervention on physical therapists' self-efficacy and implementation of motor learning practice

BACKGROUND

The application of motor learning (ML) principles and research in physical therapy can optimize patient outcomes. However, the translation of the accumulated knowledge in ML to clinical practice is limited. Knowledge translation interventions, which are designed to promote changes in clinical behaviors, have the potential to address this implementation gap. We developed, implemented, and evaluated a knowledge translation intervention for ML implementation that focuses on building clinical capacity among physical therapists for the systematic application of ML knowledge in clinical practice.

METHODS

A total of 111 physical therapists underwent the intervention, which consisted of the following: (1) an interactive didactic 20-hour course; (2) an illustrated conceptual model of ML elements; and (3) a structured clinical-thinking form. Participants completed the Physical Therapists' Perceptions of Motor Learning (PTP-ML) questionnaire pre and post intervention. The PTP-ML was used to assess ML-related self-efficacy and implementation. Participants also provided post-intervention feedback. A sub-sample (n = 25) provided follow-up feedback more than a year after the completion of the intervention. Pre-post and post-follow-up changes in the PTP-ML scores were calculated. The information gathered from the open-ended items of the post-intervention feedback was analyzed to identify emerging themes.

RESULTS

Comparing pre- and post-intervention scores, significant changes were found in the total questionnaire scores, self-efficacy subscale scores, reported implementation subscale scores (P < .0001), and general perceptions and work environment subscale score (P < .005). The mean changes in the total questionnaire and self-efficacy scores also significantly exceeded the Reliable Change Index. In the follow-up sample, these changes were maintained. Participants felt that the intervention helped them organize their knowledge in a structured manner and consciously link their practice elements to concepts in ML. Discussion of clinical cases was reported to be the most valuable educational method, and the illustrated conceptual model of ML elements was the least valued. Respondents also suggested support activities to maintain and enhance the learning experience, including on-site mentorship and hands-on experience.

CONCLUSIONS

Findings support the positive effect of an educational tool, most prominently on physical therapists' ML self-efficacy. The addition of practical modeling or ongoing educational support may enhance intervention effects.

HIPPOTHERAPY IN CEREBRAL PALSY - SURVEY RESEARCH

OBJECTIVE

The aim: To assess the effects of a one-year hippotherapy programme on the physical and mental functioning of children with cerebral palsy.

PATIENTS AND METHODS

Materials and methods: The study included 15 children with cerebral palsy whose mean age was 9 years. The children participated in hippotherapy ses¬sions at the Rehabilitation Centre in Rusinowice (one-year observation). The clinical presentation was dominated by manifestations of motor and postural abnormalities caused by central nervous system damage. A survey questionnaire was used in the study to collect information about problems associated with everyday life and functioning.

RESULTS

Results: The results obtained in this study showed that spastic CP was the most common form of the disorder, affecting 8 out of 15 children (53%). It was followed by mixed CP (40%, 6 children). Among the respondents, 67% (10 people) were already familiar with hippotherapy whereas 33% did not know this method.

CONCLUSION

Conclusions: There was a strong correlation between being familiar with effects of hippotherapy and the level of education of the parent/guardian. This result had a moderate influence on the frequency of hippotherapy sessions. Systematic hippotherapy sessions helped improve physical fitness and everyday functioning in children with cerebral palsy.

Exploration of physiotherapists' use of motor control strategies for the treatment of idiopathic toe walking in children: a qualitative study

OBJECTIVES

To explore how motor control interventions are conceptualised during treatment of children with idiopathic toe walking (ITW) by physiotherapists in Australia and USA.

DESIGN

A thematic content framework qualitative design was used to triangular the theories underpinning motor control interventions and participant responses.

PARTICIPANTS

Ten paediatric physiotherapists were recruited from Australia and USA. Participation was only open to physiotherapists who provided treatment to children with ITW.

RESULTS

Physiotherapists defined the motor control interventions used for children with ITW as having the following non-hierarchical key elements: use of repetition; task scaffolding; encouraging error recognition; and, active and/or passive movements. Physiotherapists also described two superordinate themes; (1) We see motor control through the lens of how we view management and (2) Idiopathic toe walking treatment is a game with rules that are made to be broken.

CONCLUSIONS

Treatment of ITW continues to challenge clinicians. Physiotherapists viewed their approach to ITW management being evidence- informed, underpinned by motor learning theories, movement strategies and organisational treatment frameworks or guidelines to fit their individual childrens' needs. Future research should investigate if this approach affords more favourable outcomes for children with ITW gait.

Use of Motor Learning Strategies in Occupational Therapy for Children and Youth with Acquired Brain Injury

Motor learning strategies (MLS) can be used to promote motor skills acquisition in children and youth with acquired brain injury (ABI). While occupational therapists (OTs) likely use MLS in clinical practice, research has not investigated the extent and variety of their application.Aims: This study explored MLS use by OTs in pediatric ABI and factors influencing their application.Method: Individual video-recorded occupational therapy sessions for a sample of eight children/youth (ages 4-16) with ABI were evaluated via mixed methods approach. The Motor Learning Strategies Rating Instrument (MLSRI-22) quantified the extent of MLS use in each video. Directed content analysis of the videos explored the factors influencing how and when MLS were applied.Results: The most frequently used MLS were promoting problem solving, encouragement, directing attention to the body, permitting errors as part of learning, repetitive practice, and whole practice. Three themes described how and when the OTs used MLS: 1) Getting buy-in, 2) Going with the flow, and 3) Movement and thinking go hand-in-hand.Conclusions: The OTs frequently used MLS with children with ABI, appearing to select MLS based on factors related to the child, task, and environment. These findings are fundamental to future exploration of OT decision-making and evaluation of MLS effectiveness.

Measure of early vision use: initial validation with parents of children with cerebral palsy

PURPOSE

To report initial psychometric evidence on the Measure of Early Vision Use.

METHOD

Data on performance of the Measure of Early Vision Use scale were collected from 100 parents of children with cerebral palsy aged 0-12 years via online survey. Psychometric evaluation included assessment of scale dimensionality using Classical Test Theory and hypothesis testing for evidence of construct validity.

RESULTS

Principal components analysis of the 14-item parent-rated Measure of Early Vision Use revealed one component with an eigenvalue of 9.343, explaining 66.7% of variance; internal consistency was high (Cronbach's α = 0.96). Total scores ranged from 15-56 (Mean 42.8, standard deviation = 10.6). The results support seven pre-defined hypotheses including statistically significant differences in MEVU-total scores between children with and without parent-reported cerebral visual impairment.

CONCLUSIONS

Measure of Early Vision Use is the first assessment tool to describe 'how vision is used' in children with cerebral palsy. Results provide preliminary evidence that the measure comprises a unidimensional construct, sufficient construct validity, and feasibility as a parent-completed online assessment. Findings on internal structure provide foundational evidence and require further testing with Confirmatory Factor Analysis or Rasch Analysis.IMPLICATIONS FOR REHABILITATIONThe Measure of Early Vision Use is a new instrument to describe the use of basic visual abilities and is feasible to use as a parent-completed online questionnaire.The Measure of Early Vision Use is a unidimensional scale with sufficient construct validity to supports its use as a measure of 'how vision is used' without confounding visual ability with the reason why it might be impaired (e.g., cerebral vision impairment, motor limitations, or cognition).There is potential for the Measure of Early Vision Use to support early intervention planning for children with (or at high risk of) cerebral palsy.

Testing a new active learning approach to advance motor learning knowledge and self-efficacy in physical therapy undergraduate education

BACKGROUND

Motor learning (ML) science is foundational for physical therapy. However, multiple sources of evidence have indicated a science-practice gap. Clinicians report low self-efficacy with ML concepts and indicate that the lack of access to systematic training is a barrier for practical implementation. The general goal of this preliminary study was to describe the effects of a new educational intervention on physical therapy student's ML self-efficacy and knowledge.

METHODS

Self-efficacy was assessed with the Physical Therapists' Perceptions of Motor Learning questionnaire. Data was acquired from third-semester students before their participation in the ML educational intervention. Reference self-efficacy data was also acquired from physical therapy professionals and first and last-semester students. The educational intervention for third-semester students was designed around an established framework to apply ML principles to rehabilitation. A direct experience, the "Learning by Doing" approach, in which students had to choose a motor skill to acquire over 10 weeks, provided the opportunity to apply ML theory to practice in a personally meaningful way. After the intervention self-efficacy was re-tested. ML knowledge was tested with an objective final exam. Content analysis of coursework material was used to determine how students comprehended ML theory and related it to their practical experience. The Kruskal-Wallis and Mann-Whitney U tests were used to compare self-efficacy scores between the four groups. Changes in self-efficacy after the educational intervention were analyzed with the Wilcoxon test. Spearman rank correlation analysis was used to test the association between self-efficacy and final exam grades.

RESULTS

By the end of the intervention, students' self-efficacy had significantly increased (p < 0.03), was higher than that of senior students (p < 0.00) and experienced professionals (p < 0.00) and correlated with performance on an objective knowledge test (p < 0.03). Content analysis revealed that students learned to apply the elements of ML-based interventions present in the scientific literature to a real-life, structured ML program tailored to personal objectives.

CONCLUSIONS

Positive improvements were observed after the intervention. These results need confirmation with a controlled study. Because self-efficacy mediates the clinical application of knowledge and skills, systematic, active training in ML may help reduce the science-practice gap.
