Educators' Perspectives on the Teaching and Learning of Type 2 Diabetes Content in Physiotherapy Programmes across Canada

Purpose

This qualitative descriptive study researched educators' perspectives of type 2 diabetes (T2D) Teaching and learning, in physiotherapy (PT) programmes across Canada.

Methods

Faculty members and clinical instructors from the 15 PT programmes in Canada were contacted. Online surveys collected data on the educators' professional background and perspectives on T2D in the PT curriculum. One-on-one telephone interviews were conducted and thematic analysis was used to generate themes and codes from the interview transcripts.

Results

Ten educators from 10 universities completed the survey. Seven of the 10 educators also participated in a telephone interview. Survey responses revealed that T2D content is taught predominantly through case studies and lectures. Of the 10 respondents, six reported that the curriculum does not devote adequate time to T2D content, and nine reported they "strongly agree" or "agree" that T2D is an essential component of the PT curriculum. The interviews revealed that T2D content varies across PT programmes. The educators agreed that T2D is a common condition seen in practice, there is a role for PT intervention, and T2D content is limited by classroom time.

Conclusions

Educators noted challenges integrating more T2D content in the curriculum and said that PT clinical contributions for people living with T2D are underutilized. Additional evidence-informed rationale is needed to explore optimal integration of T2D content in PT programmes.

Effect of Diabetes on Tendon Structure and Function: Not Limited to Collagen Crosslinking

Diabetes mellitus (DM) is associated with musculoskeletal complications-including tendon dysfunction and injury. Patients with DM show altered foot and ankle mechanics that have been attributed to tendon dysfunction as well as impaired recovery post-tendon injury. Despite the problem of DM-related tendon complications, treatment guidelines specific to this population of individuals are lacking. DM impairs tendon structure, function, and healing capacity in tendons throughout the body, but the Achilles tendon is of particular concern and most studied in the diabetic foot. At macroscopic levels, asymptomatic, diabetic Achilles tendons may show morphological abnormalities such as thickening, collagen disorganization, and/or calcific changes at the tendon enthesis. At smaller length scales, DM affects collagen sliding and discrete plasticity due to glycation of collagen. However, how these alterations translate to mechanical deficits observed at larger length scales is an area of continued investigation. In addition to dysfunction of the extracellular matrix, tendon cells such as tenocytes and tendon stem/progenitor cells show significant abnormalities in proliferation, apoptosis, and remodeling capacity in the presence of hyperglycemia and advanced glycation end-products, thus contributing to the disruption of tendon homeostasis and healing. Improving our understanding of the effects of DM on tendons-from molecular pathways to patients-will progress toward targeted therapies in this group at high risk of foot and ankle morbidity.

The Role of Physical Therapists in Fighting the Type 2 Diabetes Epidemic

BACKGROUND

In 2014, the total prevalence of diabetes was estimated to be 422 million people worldwide. Due to the aging population and continued increase in obesity rates, the prevalence is expected to rise to 592 million by 2035. Diabetes can lead to several complications, including cardiovascular disease, stroke, peripheral arterial disease, nephropathy, neuropathy, retinopathy, lower extremity amputation, and musculoskeletal impairments.

CLINICAL QUESTION

Up to 80% of patients referred for outpatient physical therapy have diabetes or are at risk for diabetes, providing an opportunity for physical therapists to intervene. Therefore, we asked, "What is the role of physical therapists in fighting the diabetes epidemic?"

KEY RESULTS

Physical therapists commonly prescribe physical activity for the treatment of diabetes and other chronic diseases, such as cardiovascular disease and osteoarthritis. Physical therapists may also screen for risk factors for diabetes and diabetes-related complications and modify traditional musculoskeletal exercise prescription accordingly. Physical therapists must advocate for regular physical activity as a key component of the treatment of chronic diseases in all patient interactions.

CLINICAL APPLICATION

This commentary (1) describes the diabetes epidemic and the health impact of diabetes and diabetes-related complications, (2) highlights the physical therapist's role as front-line provider, and (3) provides recommendations for physical therapists in screening for diabetes risk factors and diabetes-related complications and considerations for patient management. We focus on type 2 diabetes. J Orthop Sports Phys Ther 2020;50(1):5-16. Epub 28 Nov 2019. doi:10.2519/jospt.2020.9154.

Geriatric Rehabilitation Should Not Be an Oxymoron: A Path Forward

Older adults are the fastest growing segment of our population and contribute greatly to the high costs of health care. The primary concern among older adults seeking health care is maintaining or improving functional independence. This concern is the focus of both rehabilitative care and geriatric medicine; however, collaboration between these fields can be hampered by a lack of mutual understanding of the fundamental principles of the other field. We describe 3 steps that can be implemented at an organizational or individual level to bridge the fields of geriatric medicine and rehabilitation, allowing them to better serve older patients. These include (1) recognizing the interwoven concepts of multimorbidity, function, and frailty; (2) communicating with a common language; and (3) synthesizing our knowledge from both fields.

Outpatient physical therapy cardiovascular assessment: Physical therapist perspective and experience

Background: Physical therapists are recognized healthcare providers who play an important role in cardiovascular disease prevention. Heart rate (HR) and blood pressure (BP) are important parameters in cardiovascular risk assessment; however, physical therapists do not usually integrate them into clinical practice. Therefore, this study aimed to examine the current practice and opinion of outpatient physical therapists toward HR and BP measurements in clinics. Methods: A 12-item survey questionnaire was distributed to outpatient physical therapists. Five senior staff from different specialties, including orthopedic, neurology, pediatric, cardiopulmonary, and sport specialties, participated in a focus group interview to gather their opinions. Results: In total, 285 (56%: male) physical therapists participated. Only 68 (24%) measured HR and BP; of these, 27 (41%) used manual sphygmomanometers. Nearly one-fifth reported that cardiovascular adverse events, such as syncope and chest pain, occurred during therapeutic exercise of their patients and were the highest among the sport and orthopedic physical therapists. Most physical therapists felt that measuring cardiovascular indices is not their job and does not add value to their treatment plan. Conclusion: Majority of the physical therapists were not measuring HR and BP during clinical assessment, although some reported cardiovascular adverse events occurring in their patients.

Safety of lower extremity neurodynamic exercises in adults with diabetes mellitus: a feasibility study

OBJECTIVES

Neurodynamic exercises aim to improve neural mechanosensitivity in order to promote pain-free movement and function. People with diabetes mellitus (DM) may be candidates for neurodynamic exercises to address common DM-related impairments such as reduced lower extremity range of motion (ROM) and altered neural mechanosensitivity. However, no studies have examined the safety and immediate effects of neurodynamic exercise in people with DM. This study aims to determine the feasibility of applying neurodynamic exercises in adults with DM by evaluating the rate of adverse events and quantifying immediate changes in straight leg raise (SLR) ROM.

METHODS

This quasi-experimental study included 20 people with DM who performed a series of neurodynamic exercises on their right leg. Their left leg was used as an internal control. SLR testing was performed before and immediately after these exercises. Adverse events were monitored, including provocation of their neuropathy symptoms or discomfort or pain.

RESULTS

All participants completed the neurodynamic exercises without provocation of their neuropathy symptoms. No pain was reported and only one participant had minor discomfort with one exercise; a <30-s calf cramp. The right SLR ROM increased by an average of 5.2°-5.3° (p < 0.01) with no change on the left.

DISCUSSION

This study demonstrated that lower extremity neurodynamic exercises are safe in adults with DM and may create small immediate improvements in SLR testing. Further research is indicated to investigate the safety and efficacy of neurodynamic exercises performed over multiple sessions.

Impairment of balance in elderly subjects with type 2 diabetes

[Purpose] The purpose of this study was to investigate balance among elderly subjects with type 2 diabetes. [Subjects and Methods] Twelve subjects with type 2 diabetes and 15 age-matched controls were examined. Balance was assessed by a computerized device while the subjects were standing. [Results] Subjects with diabetes exhibited significantly more sway than control subjects while standing on a balance platform. [Conclusion] Our findings suggest that diabetes impairs balance when compared with that in normal elderly subjects.

Utilization and clinical outcomes of outpatient physical therapy for medicare beneficiaries with musculoskeletal conditions

BACKGROUND

Medicare beneficiaries frequently receive physical therapy for musculoskeletal conditions. Little information is available about this care.

OBJECTIVE

The purposes of this study were: (1) to describe characteristics, clinical outcomes, and utilization for Medicare beneficiaries receiving physical therapy in outpatient clinics within one integrated health care system; (2) to compare characteristics, outcomes, and utilization based on the body region affected; and (3) to examine factors predictive of outcomes and utilization.

DESIGN

This was a prospective, longitudinal study.

METHODS

Medicare beneficiaries aged 65 years or older (n=1,840 episodes of care) participated in the study. Descriptive statistics were calculated for patient characteristics and outcomes. Comparisons were made based on body region. Regression models evaluated factors associated with change in pain, improved outcome, and utilization.

RESULTS

The patients' mean age was 74.2 years (SD=6.3), and 65.3% were female. The most common body regions were the lumbar spine, shoulder, and knee, collectively accounting for 71.3% of the episodes of care. Patients attended a mean of 6.8 visits (SD=4.7), and 63.9% experienced an improved outcome. Episodes of care for lumbar spine conditions had less reduction in pain, whereas shoulder conditions and foot/ankle conditions showed the greatest improvement. Care for hip conditions was least likely to result in an improved outcome. Knee conditions were most likely to have an improved outcome. Care for shoulder and knee conditions had the highest number of visits. Factors associated with greater reduction in pain and improved outcomes included greater initial pain or disability and attending more visits. Factors associated with greater utilization included a postsurgical condition and higher initial pain rating. Limitations The study was performed in one geographic region within a single health care delivery system.

CONCLUSION

The results provide information on outcomes of physical therapy for Medicare beneficiaries in one health care system. Further research is needed to examine optimal utilization and care for these patients.

Epidemiology of diabetes and diabetes-related complications

In 2005, it was estimated that more than 20 million people in the United States had diabetes. Approximately 30% of these people had undiagnosed cases. Increased risk for diabetes is primarily associated with age, ethnicity, family history of diabetes, smoking, obesity, and physical inactivity. Diabetes-related complications--including cardiovascular disease, kidney disease, neuropathy, blindness, and lower-extremity amputation--are a significant cause of increased morbidity and mortality among people with diabetes, and result in a heavy economic burden on the US health care system. With advances in treatment for diabetes and its associated complications, people with diabetes are living longer with their condition. This longer life span will contribute to further increases in the morbidity associated with diabetes, primarily in elderly people and in minority racial or ethnic groups. In 2050, the number of people in the United States with diagnosed diabetes is estimated to grow to 48.3 million.

RESULTS

from randomized controlled trials provide evidence that intensive lifestyle interventions can prevent or delay the onset of diabetes in high-risk individuals. In addition, adequate and sustained control of blood sugar levels, blood pressure, and blood lipid levels can prevent or delay the onset of diabetes-related complications in people with diabetes. Effective interventions, at both the individual and population levels, are desperately needed to slow the diabetes epidemic and reduce diabetes-related complications in the United States. This report describes the current diabetes epidemic and the health and economic impact of diabetes complications on individuals and on the health care system. The report also provides suggestions by which the epidemic can be curbed.

Excessive adipose tissue infiltration in skeletal muscle in individuals with obesity, diabetes mellitus, and peripheral neuropathy: association with performance and function

BACKGROUND AND PURPOSE

The primary purpose of this study was to report differences in calf intermuscular adipose tissue (IMAT), muscle strength (peak torque), power, and physical function in individuals with obesity, diabetes mellitus (DM), and peripheral neuropathy (PN) compared with those without these impairments. A secondary purpose was to assess the relationship between IMAT and muscle strength, power, and physical function.

SUBJECTS AND METHODS

Six participants with obesity, DM, and PN (2 women, 4 men; mean age=58 years, SD=10; mean body mass index=36.3, SD=5; mean modified Physical Performance Test [PPT] score=22, SD=3) and 6 age- and sex-matched control subjects without these impairments were assessed and compared in muscle strength, muscle power, physical functioning, and muscle and fat volume, including IMAT in the calf muscles. Muscle, adipose tissue, and IMAT volumes of each calf were quantified by noninvasive magnetic resonance imaging. Muscle strength and power of the plantar-flexor and dorsiflexor muscles were quantified using isokinetic dynamometry. The modified PPT was used to assess physical function.

RESULTS

Leg muscle and fat volumes were similar between groups, although IMAT volumes were 2.2-fold higher in the subjects with obesity, DM, and PN (X=120 cm(3), SD=47) than in the control subjects (X=54 cm(3), SD=41). Muscle strength, muscle power, ratio of leg muscle power to leg muscle volume, and modified PPT scores were lower in subjects with obesity, DM, and PN compared with the control subjects.

DISCUSSION AND CONCLUSION

The data indicate that excess fat infiltration in leg skeletal muscles is associated with low calf muscle strength, low calf muscle power, and impaired physical function in individuals who are obese with DM and PN.
