Movement System Diagnosis: A Consensus-Based Position for Pediatric Movement Specialists

PURPOSE

To offer a consensus for pediatrics clinicians, educators, and researchers on the use of movement system (MS) and review evidence that supports physical therapists (PTs) as movement experts.

SUMMARY OF KEY POINTS

This paper describes the MS and discusses how a MS diagnosis (Dx) can lead to most effective interventions and plans of care (POC) in pediatrics. Three cases illustrate using organized formulation of MS Dxs and how a MS Dx assists in choosing affective interventions for the POC.

CONCLUSIONS

Pediatric PTs are movement specialists designing individualized plans of care to meet functional goals in real world conditions. Using consistent terms to establish MS Dx will enable effective communication, and a foundation for interventions across the lifespan.

RECOMMENDATIONS

Adopting MS Dx framework will support and assist students of physical therapy, entry level and experienced clinicians, educators, and researchers with a critical decision-making process for formulating optimal family centered care.

The Movement System and Diagnosis: Are We There Yet?

In the 29th Maley lecture, Phil McClure PT, PhD, FAPTA, shares a Perspective regarding the movement system and diagnosis. Despite declarations from the House of Delegates >10 years ago, the concept of a movement system has not been widely embraced in either education or practice. In this perspective, he offers critical analysis and 3 proposals that could potentially make the concept of a movement system more relevant and meaningful. The first is to operationally define the movement system, arguing that the current definition is too vague and not operational, and therefore not meaningful. The second is to intentionally separate the movement system from any specific diagnostic classification scheme which would allow the focus to remain on movement and movement analysis. He argues that diagnostic classification schemes require a biopsychosocial framework and that movement, while important, cannot be the only consideration. The third proposal is that diagnostic schemes must be developed by clinical scientists through appropriate research guided by sound theory, not by administrative or political process. He further argues that a greater focus on determining which patients are likely to be helped by physical therapists is necessary and offered the example of developing "appropriateness criteria" as a tool toward promoting value-based care. Achieving broad consensus around these proposals could unify our professional focus and assist toward the vision of optimizing movement to enhance the human experience.

The Bobath concept (NDT) in adult neurorehabilitation: a scoping review of conceptual literature

PURPOSE

This scoping review aims to describe how Bobath concept is conceptualized, operationalized, and studied in adult neurorehabilitation.

METHODS

The Joanna Briggs Institute (JBI) and the Preferred Reporting Items for Scoping Reviews (PRISMA-ScR) guidelines were adopted. Non-scientific and research articles were searched in electronic databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, Web of Science, ScienceDirect, and Physiotherapy Evidence Database (PEDro), with the keywords "Bobath" or "Neurodevelopmental Treatment", published in English, Spanish, and Portuguese, between 2013 and 2023.

RESULTS

Of the 78 publications identified, 31 articles addressed the conceptual underpinnings of Bobath concept (seven theoretical papers, seven Delphi/surveys/mixed methods studies, four qualitative studies, one scoping review, 10 letters to the editor, and two editorials), comprising five themes: (a) theoretical principles; (b) clinical principles; (c) clinical reasoning; (d) conceptualizing movement; and, current (e) evidence debate. The revised definition and the Model of Bobath Clinical Practice provide a clarification of the unique aspects of Bobath concept. A new clinical skill was identified beyond facilitation - visuospatial kinesthetic perception - as well as how Bobath experts conceptualize movement, which are all integral to clinical reasoning.

CONCLUSIONS

This review provides an updated Bobath clinical framework that gathers the theoretical foundations and clinical practice principles that require careful consideration in the design of future intervention studies. Implications for rehabilitationThis scoping review consolidates the clinical and theoretical principles of contemporary Bobath practice, providing a clear framework for clinicians.The Model of Bobath Clinical Practice (MBCP) framework enables detailed documentation of movement analysis and movement diagnosis, guiding clinical reasoning and interventions.This review identifies fundamental principles and practices to inform future Bobath intervention studies, ensuring their clinical relevance.A framework with specific recommendations has been developed to guide Bobath intervention studies, enhancing the integration of clinical practice, education, and research.

Physiotherapy management focusing on proprioceptive impairment in a patient with gait and balance impairments following stroke: A case report

BACKGROUND

Proprioceptive impairment contributes to gait and balance impairments in patients with stroke. Diagnosis functional impairments and evaluation treatment efficacy require quantitative proprioception assessment. However, proprioception assessment has remained limited to ordinal scale measurement, with a lack of ratio scale measurements.

PURPOSE

This case report describes a physiotherapy management program focusing on proprioceptive impairment in patients with stroke using quantitative tests such as Threshold to Detect Passive Motion (TDPM) and Joint Position Sense (JPS).

CASE DESCRIPTION

A63-year-old male patient with an acute pontine lacunar infarction was admitted to our hospital. His muscle strength, selective movement, and trunk activity were preserved. However, the Berg Balance Scale (BBS) and Gait Assessment andIntervention Tool (GAIT) score were 42 and 9 points, observing balance impairment and the buckling knee pattern with hip ataxia during gait. Based on these, TDPM and JPS using image capture were performed. In physiotherapeuticdiagnosis, proprioceptive impairments in the hip and knee joints were the primary functional impairments related to balance and gait. To address these proprioceptive impairments, a 13-day treatment protocol incorporating transcutaneous electrical nerve stimulation (intensity: sensory threshold, frequency: 100 Hz) targeting the quadriceps femoris was performed.

OUTCOMES

The patient was discharged after achieving independent ambulation and improvement in BBS (56 points) and GAIT (2 points) scores, exceeding the minimum clinically important difference. Recovery of proprioceptive impairment corresponded withimproved balance and gait ability.

CONCLUSION

Quantitatively evaluating proprioceptive impairments may provide novel rehabilitation for patients with stroke who have proprioceptive impairments and contribute to clinical decision-making.

Decreased functional mobility in individuals with mild to moderate expanded disability status from relapsing multiple sclerosis: Analysis of the Glittre-ADL test

INTRODUCTION

Multiple sclerosis (MS) is a chronic inflammatory and autoimmune disease that significantly limits an individual's activities of daily living (ADLs) and negatively affects their social participation as it progresses. The impact of activities and participation must be continuously assessed, and the Glittre-ADL is a validated test for MS to assess functional capacity in tasks similar to ADLs.

OBJECTIVE

To evaluate whether the Glittre-ADL test is a valid method for assessing functional mobility in individuals with MS and moderate disability or those who use assistive devices.

METHODS

This cross-sectional study enrolled 30 individuals in two groups: 1) MS group (n = 15); and 2) healthy control group (n = 15). The MS group underwent three functional mobility tests: 1) Glittre-ADL; 2) Timed 25-Foot Walk (T25FWT); and 3) Timed Up and Go (TUG) while the healthy group underwent only the Glittre-ADL test.

RESULTS

An association was found between the Glittre-ADL time and T25FWT (r = 0.78, p < .001) and TUG (r = 0.56, p = .030) times. In the MS group, statistically significant differences were found in time (F = 2.88, p = .038) and speed (F = 5.17, p = .024) between laps. A statistically significant difference was observed between the total time in the MS and control groups (Area Under Curve - AUC: 0.982, p < .0001). A total time > 46.0s represents the reduction of functional performance during ADLs in individuals with MS (sensitivity: 93.3%; specificity: 92.2%).

CONCLUSION

The Glittre-ADL test is a valid tool for assessing functional mobility in individuals with MS and mild to moderate disability (EDSS score ≤ 6.5).

Brazilian classification of physical therapy diagnosis

BACKGROUND

The Brazilian Classification of Physical Therapy Diagnosis, developed by the Federal Council of Physiotherapy and Occupational Therapy (COFFITO), has the constitutional objectives of standardizing ethical, scientific and social aspects of the Physical Therapy profession.

OBJECTIVE

To describe the work process, rationale and proposal for standardization of a physical therapy diagnosis classification system in Brazil.

METHODS

A working group was created to propose a standardized classification for the description and codification of physical therapy diagnoses. Some terminologies common to the International Classification of Functioning (ICF) were used to make the nomenclature of diagnoses compatible with the outcomes inherent in the field of physical therapy.

RESULTS

The Brazilian Classification of Physical Therapy Diagnosis project culminated in a physical therapy diagnosis model consisting of terms grouped by organic systems and identifying codes. In addition, an application was developed to allow professionals to use the standardized diagnostic classification in an online system.

CONCLUSION

The diagnostic classification system is expected to advance the Physical Therapy profession allowing the identification of structural and/or functional alterations in a simplified and standardised manner. From a physical therapy perspective, this classification may help to consolidate the autonomy of the Brazilian physical therapists by establishing a clearer pathway between the diagnosis and interventions.

Biomechanical Assessment Methods Used in Chronic Stroke: A Scoping Review of Non-Linear Approaches

Non-linear and dynamic systems analysis of human movement has recently become increasingly widespread with the intention of better reflecting how complexity affects the adaptability of motor systems, especially after a stroke. The main objective of this scoping review was to summarize the non-linear measures used in the analysis of kinetic, kinematic, and EMG data of human movement after stroke. PRISMA-ScR guidelines were followed, establishing the eligibility criteria, the population, the concept, and the contextual framework. The examined studies were published between 1 January 2013 and 12 April 2023, in English or Portuguese, and were indexed in the databases selected for this research: PubMed®, Web of Science®, Institute of Electrical and Electronics Engineers®, Science Direct® and Google Scholar®. In total, 14 of the 763 articles met the inclusion criteria. The non-linear measures identified included entropy (n = 11), fractal analysis (n = 1), the short-term local divergence exponent (n = 1), the maximum Floquet multiplier (n = 1), and the Lyapunov exponent (n = 1). These studies focused on different motor tasks: reaching to grasp (n = 2), reaching to point (n = 1), arm tracking (n = 2), elbow flexion (n = 5), elbow extension (n = 1), wrist and finger extension upward (lifting) (n = 1), knee extension (n = 1), and walking (n = 4). When studying the complexity of human movement in chronic post-stroke adults, entropy measures, particularly sample entropy, were preferred. Kinematic assessment was mainly performed using motion capture systems, with a focus on joint angles of the upper limbs.

A proposal for a universal physical therapy diagnostic concept

BACKGROUND

In Canada, as in other countries, the physical therapist (PT) must make a diagnosis to comply with direct access responsibilities. This means making a diagnosis is an entry-to-practice essential competency. However, there is no consensus across physical therapy practice domains and contexts regarding the diagnostic concept, i.e., the classification system, labelling and diagnostic format that should be used.

OBJECTIVE

To propose a universal diagnostic concept, one a PT could use regardless of their practice domain or context.

METHODS

The relevant scientific and grey literature (1986-2022) were searched and key information was synthesized.

RESULTS

Information from 194 retained documents (8506 identified) was synthesized to a list of seven essential criteria that were then used to develop a universal physical therapy diagnostic concept (PT-Dx-C). The PT-Dx-C format consists of three labels in the following order: (1) health problem, (2) primary impairment, and (3) primary activity limitation or participation restriction. Label definitions are those used by the World Health Organization. The specific health problem, impairment, and limitation or restriction making up the diagnosis are determined for each patient using valid tests and measures.

CONCLUSIONS

The PT-Dx-C is consistent with best practices and could be applied to all patients, in all PT practice domains and contexts. It reflects the PT's expertise in the human movement system and their unique contribution to health care. Furthermore, its use may allow for communication of the PT's conclusions in a manner that can be understood by others thereby facilitating collaborative practice.

The Observable Movement Quality scale for patients with low back pain (OMQ-LBP): validity and reliability in a primary care setting of physical therapy

BACKGROUND

The Observable Movement Quality scale for patients with low back pain (OMQ-LBP) is a newly developed measurement instrument for use in primary care settings of physical and exercise therapists to assess movement quality (MQ) of patients with low back pain (LBP).

OBJECTIVE

This study aims to determine validity, reliability and feasibility of the OMQ-LBP. The OMQ-LBP consists of a standardized movement circuit (performed twice) consisting of five daily activities problematic for LBP patients, which are scored with an 11-item observation list.

METHODS

Construct validity was determined by testing seven hypotheses on associations between constructs (n = 85 patients with LBP) and four hypotheses on known group differences (n = 85 patients with LBP and n = 63 healthy controls; n = 35 matched participant-patients having VAS-pain ≥ 20 mm during and/or after both circuits and healthy controls). Internal consistency was analyzed with Cronbach's alpha (n = 85 patients with LBP). For inter- and intra-rater reliability Intraclass Correlation Coefficient (ICC) values were examined (n = 14 therapists: seven primary care physical therapists and seven exercise therapists). Additionally, content validity and feasibility were determined using thematic analysis of a brief interview with participants, patients (n = 38) and therapists (n = 14).

RESULTS

After Bonferroni correction 2/7 associations between constructs and 2/4 significant group differences were confirmed. Cronbach's alpha was 0,79. The ICC-values of interrater reliability of the OMQ-LBP total score and the duration score were 0.56 and 0.99 and intra-rater reliability 0.82 and 0,93, respectively. Thematic analysis revealed five themes. Three themes elucidate that both patients and therapists perceived the content of the OMQ-LBP as valid. The fourth theme exhibits that OMQ-LBP provides a clear and unambiguous language for MQ in patients with LBP. Theme 5 depicts that the OMQ-LBP seems feasible, but video recording is time-consuming.

CONCLUSIONS

The OMQ-LBP is a promising standardized observational assessment of MQ during the five most problematic daily activities in patients with LBP. It is expected that uniform and objective description and evaluation of MQ add value to clinical reasoning and facilitate uniform communication with patients and colleagues.

Skeletal Muscle Measurements in Pediatric Hematology and Oncology: Essential Components to a Comprehensive Assessment

Children with hematologic and oncologic health conditions are at risk of impaired skeletal muscle strength, size, and neuromuscular activation that may limit gross motor performance. A comprehensive assessment of neuromuscular function of these children is essential to identify the trajectory of changes in skeletal muscle and to prescribe therapeutic exercise and monitor its impact. Therefore, this review aims to (a) define fundamental properties of skeletal muscle; (b) highlight methods to quantify muscle strength, size, and neuromuscular activation; (c) describe mechanisms that contribute to muscle strength and gross motor performance in children; (d) recommend clinical assessment measures; and (e) illustrate comprehensive muscle assessment in children using examples of sickle cell disease and musculoskeletal sarcoma.

The Use of Movement Scripts for Clinical Reasoning in Physical Therapist Education and Practice

The purpose of this Perspective is to present an application of script-based reasoning to physical therapist education and practice. Illness script-based reasoning has been described as a cognitive strategy for medical practitioners to diagnose and manage health conditions. Analogous to this medical model of patient management, "movement scripts" can be used by physical therapists in clinical reasoning. Movement scripts use features of the human movement system to recognize, categorize, and substantiate clinical problems and can be used to facilitate the development of master adaptive learners across the spectrum of physical therapist education and practice. Movement scripts are also consistent with the concept of the "human body as teacher" as the signature pedagogy proposed by the National Study of Excellence and Innovation in Physical Therapy Education. Movement of the human body, as captured by the concept of the human movement system, is a vehicle for lifelong adaptive learning for the physical therapist. Script-based learning and practice are consistent with other elements of this model, including practice-based learning and the creation of adaptive expertise. As the role of the movement system as a guide to physical therapist practice continues to evolve, movement scripts can provide a structure to facilitate development of clinical reasoning skills for physical therapist practice and education.

Application of the 4-Element Movement System Model to Sports Physical Therapy Practice and Education

The 4-Element Movement System Model describes primary elements (motion, force, motor control, and energy) essential to the performance of all movements. The model provides a framework or scaffolding which allows for consistent processes to be used in examination and intervention decisions. The process starts with task identification followed by a systematic observation of control, amount, speed, symmetry, and symptoms during movement. Testable hypotheses are generated from the observations which inform the examination and the interventions. This commentary describes the use of the 4-Element Movement System Model in entry level and post-graduate residency educational programs and in clinical care with three common sports-related diagnoses.

A Multi-Systems Approach to Human Movement after ACL Reconstruction: The Integumentary System

Postoperative management of anterior cruciate ligament (ACL) reconstruction has traditionally focused on the evaluation and intervention of musculoskeletal components such as range of motion and patients' reports of function. The integumentary system can provide early indications that rehabilitation may be prolonged due to protracted or poor healing of the incision sites. Full evaluation of the reconstruction over time, including direction of the incisions, appearance of surgical sites, level of residual innervation, and health of the individual should be considered when determining time-based goals and plans for returning an athlete to activity. Skin care techniques should be used to minimize strain and promote wound healing at the surgical sites, which in turn allows for implementation of other interventions that target other body systems such as locomotion, strength training, and cardiopulmonary conditioning. The integration of the integumentary system with cardiovascular, neurological, and muscular systems is required for a successful return to activity. A multi-physiologic systems approach may provide a unique viewpoint when aiming to attain a greater appreciation of the integumentary system and its integration with other body systems following ACL reconstruction. The purpose of this clinical commentary is to discuss integumentary considerations within a multi-physiologic systems approach to human movement after ACL reconstruction, including an anatomical review, key elements of assessment, and integrated intervention strategies.

APTA Cross Sections and Academies Recommendations for COVID-19 Core Outcome Measures

The novel coronavirus (COVID-19) emerged as a major health concern within the United States in early 2020. Because this is a novel virus, little guidance exists for best practice to evaluate this population within the field of physical therapy.

Movement System Diagnoses for Balance Dysfunction: Recommendations From the Academy of Neurologic Physical Therapy's Movement System Task Force

The movement system was identified as the focus of our expertise as physical therapists in the revised vision statement for the profession adopted by the American Physical Therapy Association in 2013. Attaining success with the profession's vision requires the development of movement system diagnoses that will be useful in clinical practice, research, and education. To date, only a few movement system diagnoses have been identified and described, and none of these specifically address balance dysfunction. Over the past 2 years, a Balance Diagnosis Task Force, a subgroup of the Movement System Task Force of the Academy of Neurologic Physical Therapy, focused on developing diagnostic labels (or diagnoses) for individuals with balance problems. This paper presents the work of the task force that followed a systematic process to review available diagnostic frameworks related to balance, identify 10 distinct movement system diagnoses that reflect balance dysfunction, and develop complete descriptions of examination findings associated with each balance diagnosis. A standardized approach to movement analysis of core tasks, the Framework for Movement Analysis developed by the Academy of Neurologic Physical Therapy Movement Analysis Task Force, was integrated into the examination and diagnostic processes. The aims of this perspective paper are to (1) summarize the process followed by the Balance Diagnosis Task Force to develop an initial set of movement system (balance) diagnoses; (2) report the recommended diagnostic labels and associated descriptions; (3) demonstrate the clinical decision-making process used to determine a balance diagnosis and develop a plan of care; and (4) identify next steps to validate and implement the diagnoses into physical therapist practice, education, and research.

IMPACT

The development and use of diagnostic labels to classify distinct movement system problems is needed in physical therapy. The 10 balance diagnosis proposed can aid in clinical decision making regarding intervention.

The 4-Element Movement System Model to Guide Physical Therapist Education, Practice, and Movement-Related Research

The movement system has been adopted as the key identity for the physical therapy profession, and recognition of physical therapists' primary expertise in managing movement dysfunction is an important achievement. However, existing movement system models seem inadequate for guiding education, practice, or research. Lack of a clear, broadly applicable model may hamper progress in physical therapists actually adopting this identity. We propose a model composed of 4 primary elements essential to all movement: motion, force, energy, and control. Although these elements overlap and interact, they can each be examined and tested with some degree of specificity. The proposed 4-element model incorporates specific guidance for visual, qualitative assessment of movement during functional tasks that can be used to develop hypotheses about movement dysfunction and serve as a precursor to more quantitative tests and measures. Human movement always occurs within an environmental context and is affected by personal factors, and these concepts are represented within the model. The proposed scheme is consistent with other widely used models within the profession, such as the International Classification of Functioning, Disability and Health and the Patient Management Model. We demonstrate with multiple examples how the model can be applied to a broad spectrum of patients across the lifespan with musculoskeletal, neurologic, and cardiopulmonary disorders.

Examining Conductive Education: Linking Science, Theory, and Intervention

Recognized in many European countries and Canada as a valid form of therapeutic and educational rehabilitation, conductive education (CE) emphasizes cognitive and motor learning principles for movement reeducation. This article illustrates how CE incorporates motor control and motor learning theories in conjunction with unique facilitation concepts, including rhythmic intention, task series, tailored low-tech equipment, and traditional facilitation concepts such as developmental sequence, manual facilitations, and multimodal interventions. Uniquely, CE brings together task series practice and learning, including a lying program, sitting program, standing program, and walking program, along with activities of daily living within a group treatment model. The conductor uses cadence and rhythmic intention to encourage movement exploration in a scripted plan of care. The participants are active learners and use CE slatted equipment to help support movements. Full participation, to the best of the learners' ability, is realized with activity modifications made by the conductor. Increased motor control arises through repetition, practice, functional context, and sensory feedback that provide guidance for intention and voluntary movement. Motor control and motor learning theories are foundational principles of CE. Individuals with neurologic injuries, including cerebral palsy, stroke syndrome, Parkinson disease, and traumatic brain injury, can benefit from CE. To date, although research studies cannot objectively compare one person's movement skills with another's, new research surrounding motor control and motor learning illustrates and supports the principles and practice of CE. CE is an educational therapy model for teaching and developing new movement skills for individuals with neurologic impairments. This article connects the current science of movement and describes the unique principles involved with CE delivery as an intervention for individuals with neurologic impairments.

Standardizing Outcome Assessment in Parkinson Disease: A Knowledge Translation Project

BACKGROUND AND PURPOSE

Rehabilitation therapists do not consistently utilize standardized outcome measures. The purpose of this study was to develop and implement a tailored knowledge translation (KT) intervention to facilitate application of standardized outcome measures used in patients with Parkinson disease (PD) receiving outpatient rehabilitation.

METHODS

Four clinics within a hospital-based outpatient system including physical therapists (n = 7) and occupational therapists (n = 2) collaborated with researcher clinicians. A mixed-methods study, using the knowledge to action (KTA) framework, was executed to standardize the assessment battery completed on patients with PD. The project was titled iKNOW-PD (integrating KNOWledge translation for Parkinson Disease).

RESULTS

Four measures were selected for iKNOW-PD (9-Hole Peg Test, miniBESTest, 10-m walk test, and 5 times sit-to-stand). A multimodal intervention that overcame specific identified barriers (equipment, time) was implemented to ensure successful uptake. Consistency of utilizing iKNOW-PD measures on initial evaluation and discharge, across therapists and clinics, was evaluated. Therapists significantly increased the use of iKNOW-PD measures from 1.9 to 3.1 on initial evaluation (P < 0.001). The 10-meter walk test demonstrated the greatest uptake (>50%) from pre-iKNOW-PD to post-iKNOW-PD.

DISCUSSION AND CONCLUSIONS

Standardizing outcome assessment for persons with PD in an outpatient setting can be successfully implemented. Overcoming identified barriers and capitalizing on facilitators promoted the uptake of standardized outcomes. Following the 6-month intervention period, therapists endorsed an improvement in their application of standardized measures and labeled iKNOW-PD as a positive experience that allowed them to minimize variability in practice.Video Abstract available for more insights from the authors (see the Video, Supplemental Content 1, available at: http://links.lww.com/JNPT/A329).

Video-Based Motion Analysis Use: A National Survey of Orthopedic Physical Therapists

OBJECTIVES

Motion analysis is performed by physical therapists to assess and improve movement. Two-dimensional video-based motion analysis (VBMA) is available for smartphones/tablets and requires little to no equipment or cost. Research on VBMA use in clinical practice is limited. The purpose of this study was to examine the current use of VBMA in orthopedic physical therapist practice.

METHODS

Members of the Academy of Orthopaedic Physical Therapy completed an online survey. Questions examined frequency of VBMA use, reasons for use, facilitators/barriers, device/apps used, practice patterns, other certificates/degrees, and demographic information.

RESULTS

Among the final analysis sample of 477 respondents, 228 (47.8%) use VBMA. Of 228 VBMA users, 91.2% reported using it for ≤25% of their caseload, and 57.9% reported using their personal device to capture movement. Reasons for using VBMA included visual feedback for patient education (91.7%), analysis of movement (91.2%), and assessment of progress (51.8%). Barriers to use included lack of device/equipment (48.8%), lack of space (48.6%), and time restraint (32.1%). Those with ≤20 years of clinical experience (odds ratio [OR] = 1.83, 95% CI = 1.21-2.76), residency training (OR = 2.49, 95% CI = 1.14-5.43), and fellowship training (OR = 2.97, 95% CI = 1.32-6.66), and those from the West region of the United States (OR = 1.66, 95% CI = 1.07-2.56) were more likely to use VBMA.

CONCLUSIONS

More than 50% of surveyed orthopedic physical therapists do not use VBMA in clinical practice. Future research should be directed toward assessing reliability and validity of VBMA use by smartphones, tablets, and apps and examining whether VBMA use enhances treatment outcomes. Data security, patient confidentiality, and integration into the electronic medical record should be addressed.

IMPACT

This study is the first to our knowledge to describe the use of VBMA in orthopedic physical therapist practice in the United States. It is the first step in understanding how VBMA is used and might be used to enhance clinical assessment and treatment outcomes.

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

BACKGROUND

The Observable Movement Quality (OMQ) Scale measures generic movement quality. Each item of the OMQ Scale focuses on a different element; together, the 15 items assess the whole construct of movement quality.

OBJECTIVE

The aim of this study was to determine the construct validity of the OMQ Scale using 7 hypotheses defined to conform to the Consensus-Based Standards for the Selection of Health Measurement Instruments.

DESIGN

This was an exploratory validation study.

METHODS

A pediatric physical therapist assessed motor performance in 101 children using an age-specific motor test and the OMQ Scale. The direction, magnitude, and rationale for 7 hypotheses, which concerned relationships (n = 2), probability of low scores (n = 4), and difference between diagnosis subgroups (n = 1), were defined.

RESULTS

The results confirmed 6 of the 7 hypotheses, indicating sufficient construct validity. Significant positive relationships were found between OMQ Scale total scores and the severity of motor disabilities (r = 0.72) and z scores on motor tests (r = 0.60). Probabilities for low scores on OMQ Scale items-exceeding the chi-square critical value-were confirmed for children diagnosed with spasticity, psychomotor retardation, mitochondrial diseases, and ataxia; however, probabilities for low OMQ Scale item scores on strength regulation in children with ataxia were not confirmed. OMQ Scale total scores for children who were not ambulatory because of neurological conditions were significantly different from those for children who were not ambulatory because of fatigue (r = 0.66).

LIMITATIONS

The sample of children was based on theoretical assumptions about relevant variations in clinical representations; on the basis of the results, it appears that children with low strength regulation were underrepresented.

CONCLUSION

The confirmation of nearly all hypotheses supported the validity of the OMQ Scale for measuring movement quality in clinical practice in addition to standardized age-adequate motor performance tests.

Therapeutic Systems and Technologies: State-of-the-Art Applications, Opportunities, and Challenges

In this review, we present current state-of-the-art developments and challenges in the areas of thermal therapy, ultrasound tomography, image-guided therapies, ocular drug delivery, and robotic devices in neurorehabilitation. Additionally, intellectual property and regulatory aspects pertaining to therapeutic systems and technologies are addressed.
