ABSTRACT

BACKGROUND: Telehealth is becoming more prevalent in physical therapy, involving a whole host of clinical services. These services are often provided without structured training in telehealth, and no formal curricula currently exist for this purpose. OBJECTIVE: To develop a set of educational competencies (ECs) to guide instruction of telehealth-related skills in entry-level programs (i.e., Doctor of Physical Therapy), existing programs (i.e., residencies and fellowships), and potential future post-graduate programs specific to telehealth physical therapy. METHODS: Physical therapists and physical therapist assistants from diverse geographic locations and practice areas were invited to participate on an expert panel. A modified Delphi process was then used to evaluate the acceptability of draft ECs gathered from the extant literature by a steering group. Draft ECs were presented to the expert panel on a questionnaire, which asked expert participants to rate each draft EC according to applicability and clarity. Draft ECs were accepted if they met a priori established criteria for acceptability and clarity. Unendorsed ECs were revised by the steering group according to open-ended comments from respondents and presented during a subsequent round. Three rounds of surveys were undertaken. RESULTS: Thirty-eight participants formed the expert panel; 38 participants completed the Round 1 survey, 28 participants completed the Round 2 survey, and 24 participants completed the Round 3 survey. Delphi group members approved 48 ECs in the first round, 23 ECs in the second round, and 2 ECs in the third round. There were 4 ECs that remained unendorsed after the modified Delphi process. Endorsed ECs spanned 7 conceptual areas. Distinct sets of ECs characterized expected end points of first professional degree, existing residency and fellowship, and potential future telehealth physical therapy post-graduate program. CONCLUSIONS: Consensus-based ECs identified in this study may guide instruction in knowledge and skills relevant to physical therapy telehealth.

ABSTRACT

PURPOSE: This paper aims to introduce the Theory of Ethical Leadership as a possible means of actualizing the mission and vision statements of the American Physical Therapy Association as well as individual professional objectives. Specific examples of how this can be applied directly to the profession of physical therapy will be presented. DESIGN/METHODOLOGY/APPROACH: Leadership influences can profoundly affect a profession, an organization and an individual. This has led to exploring which leadership style would be most effective in moving their organization forward. Through a review of the literature, this viewpoint paper compares leadership theories present in the health-care literature, as well as why they may fall short of actualizing the mission and vision statements of the American Physical Therapy Association as well as individual professional objectives. FINDINGS: Most research has separated ethics from leadership, but all agree that to be successful, the leader needs to exhibit a strong moral compass and demonstrate positive ethical behavior. At the intersection of ethics and leadership is the emerging theory of ethical leadership. Ethical leadership is based on the premise that employees look outside of themselves for ethical guidance and that leaders have an opportunity to provide this moral awareness by making an ethical message sufficiently salient to be recognized in the organizational context as well as allowing the leader to stand out against an ethically neutral ground. ORIGINALITY/VALUE: This paper is an original work and has not been published previously, either in whole or in part. Additionally, this paper is not under consideration for publication by any other journal.

ABSTRACT

SYNOPSIS: Despite the importance of communication in person-focused care, biomedical knowledge and technical skill development are often prioritized in physical therapy education. As clinicians and educators, we contend that mindfulness and reflection nurture effective communication approaches and support physical therapists in navigating the complexity and uncertainty that comprise most clinical interactions. We suggest that clinicians be mindful of the self, the patient, and the context when interacting with patients. Although being mindful cultivates awareness and curiosity, being reflective is an active practice that can be used while deliberating about the right thing to do or say in a particular situation. In this Viewpoint, we offer clinicians and educators suggestions for engaging in mindful and reflective practices. Through the contemplative practices of mindfulness and reflection, clinicians can better cultivate their communication expertise and good practice. J Orthop Sports Phys Ther 2023;53(10):579-584.

ABSTRACT

Social determinants of health are an emerging focus within physical therapist practice, research, education, and advocacy as a necessary condition for movement system health disparities. Fundamental cause theory suggests that the sociopolitical environment sets the context for individuals' socioeconomic positioning, which determines the availability of resources that are necessary for groups and individuals to maintain health. These resources include knowledge, money, power, prestige, and social connections. Yet, it is the hierarchical organization of society that dictates both the availability of socioeconomic resources and the ability of patients and clients to use those resources to promote and maintain movement system health. The presence of social hierarchies indicates the need for physical therapists to consider social power as a key determinant of movement system health. Consideration of social power in clinical initiatives and advocacy agendas would provide a framework for physical therapists to begin the dynamic, and often, adversarial process of breaking down social hierarchies and redistributing social power, rather than simply redistributing socioeconomic resources, in pursuit of societal transformation and community-building. This Perspective discusses social power as the fundamental driver of movement system health inequalities and explores the effects of social power on exposure, susceptibility, experience, and recovery related to movement system pathology-including the influence of social power on the ability of people to acquire socioeconomic resources and convert them to health-relevant resources. This perspective concludes with recommendations for physical therapists to identify and dismantle inequalities in social power through structural competency.

ABSTRACT

BACKGROUND: Myalgic encephalomyelitis (ME) is a complex, multi-system neurological condition. The defining feature of ME is post-exertional malaise (PEM) with over 30 symptoms triggered by physical, cognitive, emotional and social activity. The cause of PEM is unclear but one area of research using cardio-pulmonary exercise tests show a reduced ventilatory anaerobic threshold (VAT) with repeated tests leading to PEM. Pacing with heart rate monitoring (HRM) provides feedback to maintain activity intensity below the VAT. There is only one piece of research investigating the use of HRM although a number of guidelines recommend it. OBJECTIVE: To identify the experiences and attitudes of people with ME towards HRM. METHODS: A 40 question online survey was devised and released on ME websites, Twitter and Facebook pages. People with ME read the information sheet and followed an online link to the survey. The survey was open for three weeks and all answers were anonymous. RESULTS: 488 people with ME completed the survey. Most participants were female, 35-50 years and with a reported illness of greater than 5 years. Over 100 types of HR monitor used. Over 30 benefits and over 30 negatives identified. HRM reduced severity of ME and severity and duration of PEM. CONCLUSION: Although there are limitations, HRM has many benefits including helping PwME to understand and manage their PEM and support them to increase their activities, including work. There is a need for more research and education of healthcare professionals in the safe use of HRM.

ABSTRACT

BACKGROUND: Existing instruments often are inappropriate to measure the effects of post-exertional malaise (PEM) and post-exertional symptom exacerbation (PESE) on activities of daily living (ADLs). A validated questionnaire to measure self-reported ability with ADLs would advance research and clinical practice in conditions like myalgic encephalomyelitis and Long Covid. OBJECTIVE: Determine the measurement properties of the PEM/PESE Activity Questionnaire (PAQ). METHODS: The PAQ is adapted from the Patient Specific Functional Scale. Respondents rated three self-selected ADLs on two 0-100 scales, including current performance compared to (1) a 'good day' and (2) before illness. Respondents provided a Burden of Functioning rating on a 0-100 scale, anchored at 0 being the activity took "No time, effort, and resources at all" and 10 being "All of my time, effort, and resources." Respondents took the PAQ twice, completing a demographic questionnaire after the first PAQ and before the second PAQ. Descriptive statistics and intraclass correlation coefficients were calculated for each scale to assess test-retest reliability. Minimum detectable change outside the 95% confidence interval (MDC95) was calculated. Ceiling and floor effects were determined when the MDC95 for average and function scores crossed 0 and 100, respectively. RESULTS: n = 981 responses were recorded, including n = 675 complete surveys. Test-retest reliability was generally fair to excellent, depending on function and scale. MDC95 values generally indicated scale responsiveness. Ceiling and floor effects were noted infrequently for specific functions. CONCLUSION: The PAQ is valid, reliable, and sensitive. Additional research may explore measurement properties involving functions that were infrequently selected in this sample.

ABSTRACT

BACKGROUND: Post-exertional malaise (PEM) is the hallmark symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) yet its diverse manifestations make it difficult to recognize. Brief instruments for detecting PEM are critical for clinical and scientific progress. OBJECTIVE: To develop a clinical prediction rule for PEM. METHOD: 49 ME/CFS and 10 healthy, sedentary subjects recruited from the community completed two maximal cardiopulmonary exercise tests (CPETs) separated by 24 hours. At five different times, subjects reported symptoms which were then classified into 19 categories. The frequency of symptom reports between groups at each time point was compared using Fisher's exact test. Receiver operating characteristics (ROC) analysis with area under the curve calculation was used to determine the number of different types of symptom reports that were sufficient to differentiate between ME/CFS and sedentary groups. The optimal number of symptoms was determined where sensitivity and specificity of the types of symptom reports were balanced. RESULTS: At all timepoints, a maximum of two symptoms was optimal to determine differences between groups. Only one symptom was necessary to optimally differentiate between groups at one week following the second CPET. Fatigue, cognitive dysfunction, lack of positive feelings/mood and decrease in function were consistent predictors of ME/CFS group membership across timepoints. CONCLUSION: Inquiring about post-exertional cognitive dysfunction, decline in function, and lack of positive feelings/mood may help identify PEM quickly and accurately. These findings should be validated with a larger sample of patients.

ABSTRACT

OBJECTIVES: To explore if physical therapists are practicing skills necessary to refer patients for musculoskeletal imaging. METHODS: An expert panel established a list of nine requisite skills to refer for musculoskeletal imaging. A blinded expert panel validated the list using a 5-point Likert scale. The skills list was examined via an electronic survey distributed to United States physical therapists. RESULTS: 4,796 respondents were included. Each of the nine skills were routinely performed by a majority of the respondents (range: 54.52-94.72%). Respondents routinely performed 6.95 (± 0.06) skills, with 67.41% routinely performing seven or more skills. Doctors of physical therapy routinely performed more imaging skills (7.15 ± 0.06) compared to their masters- (6.44 ± 0.19) and bachelors-trained (5.95 ± 0.21) counterparts (p < 0.001). Residency/fellowship-trained physical therapists were more likely to routinely perform more imaging skills (7.60 ± 0.11 vs. 6.79 ± 0.07, p < 0.001). Imaging skill performance was greater among board-certified physical therapists (7.39 ± 0.09 vs. 6.71 ± 0.08, p < 0.001) and APTA members (7.06 ± 0.07 vs. 6.65 ± 0.12, p < 0.001). CONCLUSION: Physical therapists are routinely practicing the requisite imaging skills to directly refer to a radiologist for musculoskeletal imaging.

ABSTRACT

Physical therapists are uniquely positioned through their knowledge and skills to help people become more physically active, which may reduce the consequences of physical inactivity for health-related quality of life and the global economy. The "Exercise Is Medicine" campaign was introduced in 2007. It holds that exercise may be prescribed like a medicine. Although this analogy doubtlessly has promoted innumerable life-changing conversations between clinicians and patients, there are important shortcomings to considering physical activity and exercise as medicine. In the United States, many of these shortcomings relate to how medical services are provided and remunerated. Medical care is provided in the context of exclusive groups, which are established by insurance, preferred service populations, or other characteristics that determine a basis for providing care. Exclusivity means that medical care is frequently provided in a type of club. The club structure of medical care jeopardizes the ability of nonmembers to benefit. Medical care clubs based on payment create an environment in which nonpaying customers may not benefit in the same manner as paying customers from approaches that consider exercise prescribed as medicine. This clinical perspective reviews the characteristics of exercise as a good, focusing on how it is prescribed by physical therapists. It discusses how physical therapists may become involved in the process of making exercise a public good by reducing its exclusivity. Multiple levels of involvement are recommended at the societal, community, and individual levels. These involvements may be guided by an existing construct proposed by the World Health Organization, which would bring the global physical therapy profession into a common alignment. This Perspective concludes with a discussion that anticipates the shortcomings of conceptualizing exercise as a public good to be addressed in future service delivery models.

ABSTRACT

SYNOPSIS: The components of clinical practice are complex, often ambiguous, and influenced by a wide variety of interrelated contextual factors. As appreciation grows for the impact of individuality, complexity, and uncertainty in health processes, effective translation into widespread clinical practice remains limited. In attempts to bring patients effective solutions, well-meaning physical therapists can get trapped in "idea cults," in which a favored idea is supported and others are disparaged. We recommend that physical therapists develop a practice of self-reflection marked by openness and humility to more successfully adapt to the unique needs, values, and preferences of each person. We highlight 4 ways physical therapists can cultivate a more mindful and adaptable clinical approach that can help recognize and navigate the complexities of everyday clinical practice.

ABSTRACT

The future of health care professional education is moving from a focus on the individual to embrace the health of the larger society. The COVID-19 pandemic has further highlighted the connection between social determinants and the health of populations. There are frameworks and competencies to support the delivery of population health content in the entry-level Doctor of Physical Therapy (DPT) curriculum. Three options for integrating population health content into the DPT curriculum are presented: (1) threading the content throughout the curriculum, (2) concentrating the content in 1 or 2 identified courses, and (3) offering elective courses. Each of these strategies has benefits and challenges, but threading the content throughout the curriculum provides the best opportunity to reinforce population health competencies across populations and practice settings. Experiential learning using authentic scenarios provides an ideal opportunity for students to understand population health concepts in a real-world context. Activities that incorporate interaction with other health professions broaden students' perspectives of the role of different professions for achieving population health goals. Examples of learning activities are included in 3 competency areas, Foundations of Population Health, Prevention and Health Promotion, and Health Policy. Current societal issues provide an opportunity to enhance population health education from a meaningful perspective for students. The topic of health equity presents an opportunity to tie social and political factors of population health to social justice and health outcomes. Similarly, the COVID-19 pandemic puts issues of mental health, health disparities, and health systems front and center in our understanding of population health. IMPACT: Health care practitioners are looking at health through the lens of health equity and acknowledging the impact of social and political determinants on health to address health disparities, decrease health care expenditures, and respond to changes necessitated by pandemics such as COVID-19. As health care systems and practices are rethought and reconstructed, the intentional integration of population health principles woven into the fabric of professional education is a critical component of preparing future providers. This article describes how population health concepts can be meaningfully embedded into the DPT curriculum along with providing realistic examples and activities.

ABSTRACT

This revised clinical practice guideline (CPG) addresses the distinct but related lower extremity impairments of those with a first-time lateral ankle sprain (LAS) and those with chronic ankle instability (CAI). Depending on many factors, impairments may continue following injury. While most individuals experience resolution of symptoms, complaints of instability may continue and are defined as CAI. The aims of the revision were to provide a concise summary of the contemporary evidence since publication of the original guideline and to develop new recommendations or revise previously published recommendations to support evidence-based practice.

ABSTRACT

INTRODUCTION: Research shows 54% to 93% of practicing dentists suffer from musculoskeletal disorders (MSDs), with many developing afflictions early in their careers. Studies also show that dental students are developing MSDs early in their professional education. OBJECTIVE: The research goal was to quantify the prevalence, anatomical location and initial onset of MSDs among first-year dental students. The study also assessed the students' self-reported opinion as to whether there were enough educational touchpoints to improve their ergonomics in daily activities. METHODS: At the conclusion of a 9-month preclinical restorative course, that included 2 lectures on MSDs, ergonomics, and postural cueing sessions, a dental and physical therapy faculty member administered a survey to 143 first-year dental students. This survey included questions about the history and presentation of the students' MSD symptoms and their opinion on the relative value of the educational interventions. RESULTS: There was a 96.5% response rate to the survey with 87.8% of students reporting mild to moderate pain. The cervical spine (41.7%) and hands (42.4%) were the most common areas afflicted. 55.4% reported pain commencing 1 month after starting in the simulation clinic. Over 60.9% of students "agreed" or "somewhat agreed" that the 2 sessions of hands-on ergonomic educational interventions resulted in improved biomechanics and students requested additional educational resources. CONCLUSION: Dental students are developing MSDs as soon as 1 month after commencing dental school. Dental education should include ongoing ergonomic training throughout the curriculum to help students prevent MSDs.

ABSTRACT

OBJECTIVE: Noncommunicable diseases have increased in prevalence and are now responsible for the majority of the burden of disease. Aligning entry-level (professional) physical therapist education with these changing societal needs may position physical therapists to best address them. However, no comprehensive understanding of the practices and attitudes related to population health, prevention, health promotion, and wellness (PHPW) content among accredited US professional doctor of physical therapy (DPT) programs has been established. This study aims to identify practices and attitudes related to PHPW content among accredited US DPT programs. METHODS: A mixed-methods cross-sectional design using an electronic survey was utilized. Program directors of each accredited DPT program were identified using an official Commission on Accreditation in Physical Therapy Education list and invited to ascertain the perceived importance of PHPW, describe the delivery of PHPW content, and identify factors that influence inclusion of PHPW content in US DPT programs. RESULTS: Individuals from 49% of 208 invited programs responded. Nearly all programs reported teaching prevention (96.1%), health promotion (95.1%), and wellness content (98.0%), while fewer reported teaching population health (78.4%). However, only 15% of PHPW topics were covered in depth. Facilitators and barriers to the delivery of PHPW content were reciprocal and included faculty with PHPW expertise, logistical flexibility and support, and the perceived importance of PHPW content. CONCLUSIONS: The majority of US DPT programs are teaching PHPW content. Lack of trained faculty and lack of professional competencies hinder further integration of PHPW content into curricula. IMPACT: The findings of this study highlight avenues for additional research to determine professional PHPW competencies and additional educational needs for faculty members.

ABSTRACT

BACKGROUND: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) causes significant impairment in daily activities, including the ability to pursue daily activities. Chronotropic intolerance is becoming better characterized in ME/CFS and may be the target of supportive treatment. OBJECTIVE: To document the effect of repeated intravenous (IV) saline administration on cardiovascular functioning and symptoms in a 38-year old female with ME/CFS. METHODS: The patient received 1 L of 0.9% IV saline through a central line for a total of 675 days. Single CPETs were completed periodically to assess the effect of treatment on cardiopulmonary function at peak exertion and ventilatory anaerobic threshold (VAT). An open-ended symptom questionnaire was used to assess subjective responses to CPET and self-reported recovery time. RESULTS: Improvements were noted in volume of oxygen consumed (VO2), heart rate (HR), and systolic blood pressure (SBP) at peak and VAT. Self-reported recovery time from CPET reduced from 5 days to 1-2 days by the end of treatment. The patient reported improved quality of life related, improved capacity for activities of daily living, and reduced symptoms. CONCLUSIONS: IV saline may promote beneficial effects for cardiopulmonary function and symptoms in people with ME/CFS, which should be the focus of formal study.

ABSTRACT

BACKGROUND: Post-exertional malaise (PEM) is an exacerbation of symptoms that leads to a reduction in functionality. Recognition of PEM is important for the diagnosis and treatment of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). OBJECTIVE: Symptoms following cardiopulmonary exercise testing were compared between ME/CFS patients and healthy controls. METHODS: Open-ended questionnaires were provided to subjects following two maximal exercise tests, 24 hours apart. Subjects evaluated how they felt at five time points. Responses were classified into 19 symptom categories. RESULTS: ME/CFS subjects (n = 49) reported an average of 14±7 symptoms compared to 4±3 by controls (n = 10). During the seven days afterwards, ME/CFS subjects reported 4±3 symptoms. None were reported by controls. Fatigue, cognitive dysfunction, and sleep problems were reported with the greatest frequency. ME/CFS patients reported more symptom categories at higher frequencies than controls. The largest differences were observed in cognitive dysfunction, decrease in function, and positive feelings. CONCLUSIONS: A standardized exertional stimulus produced prolonged, diverse symptoms in ME/CFS subjects. This provides clues to the underlying pathophysiology of ME/CFS, leading to improved diagnosis and treatment.

ABSTRACT

BACKGROUND: Diminished cardiopulmonary exercise test (CPET) performance indicates the physiological basis for reduced capacity for activities of daily living and work. Thus, it may be a biomarker for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). OBJECTIVE: To determine statistical properties of cardiac, pulmonary, and metabolic measurements obtained during CPET in people with ME/CFS. METHODS: Fifty-one females with ME/CFS and 10 sedentary females with similar age and body mass received cardiac, pulmonary, and metabolic measurements during 2 CPETs separated by 24 hours. Two-way analysis of variance and effect size calculations (Cohen's d) were used to assess the magnitude and statistical significance of differences in measurements between groups. Reliability of CPET measurements was estimated using intraclass correlation coefficients (ICC2,1). Responsiveness of CPET measurements was assessed using minimum detectable change outside the 95% confidence interval (MDC95) and coefficients of variation (CoV). RESULTS: CPET measurements demonstrated moderate to high reliability for individuals with ME/CFS. Comparing subjects with ME/CFS and control subjects yielded moderate to large effect sizes on all CPET measurements. MDC95 for all individuals with ME/CFS generally exceeded control subjects and CoVs for CPET measurements were comparable between groups. CONCLUSIONS: CPET measurements demonstrate adequate responsiveness and reproducibility for research and clinical applications.
