What is Global Health?

The concept of Global Health has been defined in various ways. Beaglehole and Bonita (2010) define Global Health as, “collaborative trans-national research and action for promoting health for all.” [1] It has also been defined as, “an area for study, research and practice that places a priority on improving health and achieving equity in health for  all people worldwide. Global health emphasises transnational health issues, determinants and solutions; involves many disciplines within and beyond the health sciences and promotes inter-disciplinary collaboration; and is a synthesis of population-based prevention with individual-level clinical care.” [2] Global health actions may be in response to some of the world's major health burdens such as injury and non-communicable disease (cardiovascular disease, diabetes, cancers and chronic respiratory diseases), which occur in various magnitudes across many countries, regardless of level of development. [3] [4] [5] [6]

How Do Physiotherapists Fit Into Global Health Initiatives?

According to Mickan et al (2010), “there is a clear requirement for collaboration among health workers from different professional backgrounds as no one person is able to deliver care to meet the complete needs of the patient.” [7] Collaborative Practice is noted to “[occur] when multiple health workers provide comprehensive services by working together synergistically along with their patients, their families, carers and communities to deliver the highest quality of care across settings.” [7] 
Physiotherapists are key members of collaborative inter-professional teams due to their broad scope of practice. As is typical with varying locales, the specific role of a physiotherapist varies according to the needs of the specific population in question. At the First Physical Therapy Summit on Global Health in 2007, the overarching roles of the physiotherapist as an “Agent of Change” and “Health Advocate” were discussed. [8] Some of these roles include:
  • Members of inter-disciplinary health teams for the provision of direct service [8] [9] 
  • Educators and Mentors related to [8] [9]
  1. Prevention and management of non-communicable diseases and lifestyle-related conditions (e.g. obesity, diabetes, heart disease). This was a notable priority for all geographic regions represented at the 2007 Summit. [8]
  2. Prevention of incidents such as workplace injuries
  3. Increasing physical activity levels
  4. Infection control
  5. Maternal and child health
[10]
  • Advocates to establish and/or develop education and healthcare programs that maximize local resources to ensure sustainability [9]
  • Screeners (e.g. for physical and/or sexual abuse, lifestyle conditions, HIV/AIDs, mental health conditions) [8] 
  • Referees i.e. identify conditions that require referral to other health practitioners [8] 
  • Consultants (e.g. to urban planners and government) [8] 
  • Leaders and active participants in health policy decision-making [8] 

Barriers and Solutions for Global Health Initiatives

Many barriers can limit the effects of Global Health initiatives, with considerable regional variation. The following challenges were discussed at The First Physical Therapy Summit on Global Health in 2007; [8]
  • Lack of access to physiotherapists, particularly in rural areas
  • Lack of understanding of cultural differences
  • Logistical barriers such as bad roads, lack of clean water supply, lack of appropriate waste management, poor electricity supply
  • Insufficient research into population-specific health conditions and best practices
  • Insufficient or delayed knowledge translation of existing research
  • Discrepancy between current entry-level curricula, research and the most prevalent and/or serious region-specific health conditions. o For example, there is much focus on musculoskeletal (MSK) conditions in university programs and in research circles, yet such conditions are not a leading cause of mortality. In the statistics shown at the 2007 Summit, Ischaemic Heart Disease and Cardiovascular Disease were the first and second causes of mortality in four of the five geographic regions. Only Africa did not follow this pattern. There, the primary cause of mortality is HIV/AIDs, with Ischaemic Heart Disease and Cardiovascular Disease ranking 5th and 7th in the top ten, respectively. Accidents (including Road Traffic Accidents) were ranked the 7th leading cause of mortality in the Asia Western Pacific region, the highest position calculated for that category. Although Accidents can obviously result in MSK injuries, the rankings presented at the Summit relate to mortality thus the types of MSK injuries that physiotherapists typically see would unlikely factor in to these figures. Therefore, the disproportionate dominance of MSK conditions in regards to research and physiotherapy education do not seem to be in the best interests of Global Health.
  • Insufficient recognition of and research into differences between health and health care of indigenous versus non-indigenous populations, rural versus urban populations as well as factors affecting immigrant populations [8]
The Summit also proposed the following recommendations;
  • Increase number of training institutions that offer the appropriate degree award
  • Allocate an appropriate proportion of university curricula for region-specific conditions
  • Accept internationally-trained physiotherapists for clinical shadowing experiences to promote exposure to facilities and therapeutic studies
  • Establish local Centres of Excellence through the World Health Organization and/or World Confederation for Physical Therapy,
  • Promote more research into Global Health issues, particularly where region-specific research is lacking
  • Expedite knowledge translation once research is performed
Others have proposed additional ways to enhance Global Health.
  • “Recognise chronic non-communicable diseases as a major impediment to development” [3] and provide sufficient leadership, advocacy, organizational cooperation, political backing, financial support, industrial change and research to counter these epidemics [3] [4] 
  • International service-learning – “a structured learning experience that combines community service with explicit learning objectives, preparation and reflection….a philosophy of educations that ‘emphasizes active, engaged learning with the goal of social responsibility.’” [11] 
  • Open online courses – For example, Physiopedia has run several accredited Massive Open Online Courses to provide free quality educational opportunities for physiotherapists who can then apply their new knowledge and skills in their own communities. “Perhaps the greatest value of MOOCs in the future will be for providing a means for tackling large global problems through community action” [12] 

Potential Concerns of Global Health Initiatives

[13]
“Voluntourism” is a term that has taken on a negative connotation because of the often disingenuous, condescending and ultimately short-sighted and ineffectual work that volunteers often perform in the name of Global Health. [14] [15] Even with the best of intentions, there is a risk of a negative impact to on the very community that the volunteer is trying to help. Appropriate reasons to volunteer include trying to form global partnerships and to learn from the opportunity (e.g. about historical and sociopolitical impacts on health or the role of rehabilitation professionals working in the area of global health). Inappropriate reasons include using the experience as a vacation or to look impressive on a resume. As well, it is important to understand the cultural context in which a volunteer will be working to avoid the expectation that he/she will effect fast or sweeping changes by knowing a ‘better’ way to do things. [16]Following guideline or framework can help volunteers and organizations working in Global Health ensure the work they do is meaningful and socially responsible. An example of such guidelines can be found here. 

Global Health Initiatives and Organizations

Canadian Association for Medical Relief

"The Canadian Association for Medical Relief (CAMR), founded in 2002 by Dr. Rand Askalan, is a non-for-profit organization that provides medical services in developing countries. These services may be in the form of:
  • Offering financial and social support to patients coming to Canada for medical treatment *Improving quality of care by sending medical equipment and supplies
  • Sponsoring Canadian physicians to offer free medical care
  • Supporting students during their medical training in Canada
  • Organizing educational seminars for local community physicians"[17]

"A non-profit organization that operates charitable hospitals and programs in 30 countries worldwide where patients experience the life-changing message of God’s love for them, receiving surgical treatment regardless of gender, religion, or ethnicity." [18]
For more information, please visit https://cure.org/

Global Health Division of the Canadian Physiotherapy Association

[19]
The Global Health Division (GHD) was created in 2004 as a result of the growing interest in International Health by Canadian physiotherapists. The vision of the GHD is to be a reliable and influential resource and a strong advocate group for the importance of physical therapists in the area of global health. Focusing on countries with developing and transitional economies, the GHD facilitates access to a broad range of information ranging from global health and disability issues to volunteer opportunities. The GHD harnesses the passion, interests and energy of its members from across Canada and works in collaboration with colleagues from around the world. The mission of the GHD of the CPA is to educate, advocate and motivate physical therapists from across Canada regarding Global Health.[20]
Canadian physiotherapists have been actively engaged in global health initiatives in a variety of settings on many of the world's continents. Some examples of these initiatives include the International Centre for the Advancement of Community Based Rehabilitation (ICACBR) at Queen's University supporting work in the Balkans among other countries, as well as at Dalhousie University whose physiotherapists have worked in Kuwait for a number of years. These are only a few examples of Canadian Physical Therapy organizations and universities, who have made an impact at the global level. These institutional examples are of course in addition to the numerous individual physiotherapists who have independently contributed to international health in various capacities.

Global Health Special Interest Group of the American Physical Therapy Association

"Promoting Social Responsibility & Community Engagement at Home & Abroad"[21]
"Mission: To provide resources, information, and support to SIG, Section, and APTA members regarding global health, health disparities, cultural competency, disability, and service-learning in resource-limited settings."[21]
"History: Ronnie Leavitt and Karin Schumacher co-founded the Cross-cultural and International Physical Therapy Interest Group in 1986. The group was officially recognized as a special interest group within the Health Policy and Administration Section in 1996. To reflect member interests in health equity, cultural determinants of health, and service-learning both in the United States and abroad, the group changed its name to the Global Health SIG."[21]

Medical Ministry International

"Each year, over half a million people benefit from the compassionate and quality care of our Health Centers, Project Teams, and Residency Training Programs. Founded in 1968, MMI works in over 23 countries around the world. In 2014 we provided health care services worth US$177,519,522 to 668,475 people throughout the world who typically would have had limited or no access to medical services. Our business model is unique in that we utilize volunteers both medical and non-medical to bring life-changing services to the poor. We seek to eliminate a “welfare” mentality by asking that the patients contribute to their services. This contribution may be a little, but we have found over time that if someone has invested in their care, they will follow the doctors direction and get healthy. Gone are the days of people just throwing money a problem and then those who receive the gift tossing it aside because they think its not worth something."[22]

Sanofi Pasteur's Dengvaxia: Finally, A Vaccine For Dengue
Dengue—a virus most commonly transmitted by the Aedes aegypti mosquito—infects some 400 million people yearly. It causes high fever, severe headaches, vomiting, and sometimes death. About 40 percent of the world’s population is at risk, and as the climate warms and travel increases, that risk will only climb. This year, the World Health Organization ­started recommending the first vaccine to prevent dengue, and inoculations have begun in hot zones like Brazil and the Philippines. Four viruses cause dengue, so developing a vaccine that protects against all four took researchers 20 years to do. If 20 percent of the population gets vaccinated, dengue cases could drop 50 percent within five years. Controlling dengue could also reduce the $9 billion the disease costs global economies each year.

Braeburn Pharmaceuticals' Probuphine Implant: Easy Opioid Maintenance
During treatment for opioid addiction, missing one or two doses of withdrawal meds can trigger a relapse. Once under the skin, where they stay for up to six months at a time, four matchstick-size Probuphine implants deliver a constant dose of buprenorphine, an opioid derivative that in small, steady doses combats withdrawal symptoms. The device is currently FDA-approved for patients in active recovery from opioid addiction.

Amgen's IMLYGIC: A Virus That Fights Cancer
Scientists have long known that viruses could trigger the immune system to attack cancer, but modifying the viruses without affecting our resistance to them has taken time. In late 2015, IMLYGIC became the first FDA-approved viral cancer drug. Green-lit to treat melanoma, the modified herpes virus is injected into a tumor, where it may ignite an immune response to the cancer.

Abbott's Absorb: A Disappearing Cardiac Stent
Metal stents—small tubes that unclog and heal blocked arteries—are a mainstay in cardiac surgery. But because that metal stays around indefinitely, plaque can rebuild around it. Absorb is a fully bioabsorbable stent that does the same healing work, but it dissolves when it’s finished. Made of polylactide—a biodegradable polymer also used in dissolving sutures—the device proved to be on par with its metal counterpart in clinical trials.

People with insulin-dependent diabetes stick their fingers up to 10 times a day to check their blood sugar. The FreeStyle Libre system eliminates the painful finger pricking. A small, round sensor on the upper arm contains a tiny filament that, when inserted just under the skin, continually monitors glucose. Patients use a smartphone-size scanner to check their levels. Those who used the system were in a state of low blood sugar 38 percent less often.
There are two versions of the FreeStyle Libre. A professional one, the FreeStyle Libre Pro, meant for use under a doctor’s supervision, was FDA-approved in September. A consumer version, the FreeStyle Libre, is currently being reviewed by the FDA.

THE ROLE OF PHYSIOTHERAPY IN BREAST CANCER REHABILITATION

Source: http://www.unitehealth.com.au/the-role-of-physiotherapy-in-breast-cancer-rehabilitation/

Susan Czyzo (Bachelor of Physical Education and Health, Master of Science in Physical Therapy)
The Australian Institute of Health and Welfare estimates 16,084 new cases of breast cancer in Australia in 2016, amounting to 12.3% of all new cancer diagnoses (27% of all new cancers in females) and 6.5% of all deaths from cancer. Although the incidence of breast cancer has tripled in thirty years (1982 to 2012), the likelihood of surviving at least 5 years after diagnosis is currently at 90%. Being labelled a survivor of breast cancer, however, does not automatically translate to a clean bill of health. There are a number of additional health obstacles that many women experience following breast cancer treatment. Fortunately, physiotherapists possess the skills necessary to lessen or even eliminate these obstacles.

LYMPHOEDEMA

All women who undergo breast cancer surgery are at risk of developing lymphoedema, which may not appear until months or even years post surgery. Risk is higher for women who have undergone a full axillary lymph node dissection.  Radiation treatment may also cause, or if already present, exacerbate lymphoedema. Pain, loss of range of motion and strength in the upper extremity, as well as impaired function are common effects of lymphoedema.
As exercise has shown to be a safe and essential part of lymphoedema management, physiotherapy can play a meaningful role in prevention and treatment. It’s important to be aware that different types of exercise can be beneficial. For example, sustained periods of deep inspiration such as with aerobic exercise help by enhancing venous and lymphatic return. Flexibility training, alternatively, minimizes tightness associated with scarring, a contributor to the blocking of lymphatic flow. Hydrotherapy, with the movement of water exerting a healthy level of compression on the body, is also believed to aid in improving lymphoedema.
In addition to prescribing and supervising a specialized exercise program, kinesiotaping and education on activities or movements that trigger lymphoedema are other ways that physiotherapists can assist with lymphoedema management.

BONE LOSS

The rate and magnitude of bone loss caused by cancer treatment is significantly higher than age-related bone loss in the non-cancer population. Chemotherapy-induced premature menopause and anti-estrogen therapies, for example, are believed to contribute to the increased rate and magnitude in this population.
As within the general population, initial management for decreased bone density includes education on the benefits of a lifestyle that includes, among other interventions, regular weight-bearing exercise. Physiotherapists are able to confidently advise these individuals on safe exercise options to maximize bone integrity.

 UPPER EXTREMITY DYSFUNCTION

Decreased range of motion, rotator cuff strain, adhesive capsulitis, paraesthesia and weakness are all common developments in the upper extremity post breast cancer surgery and/or radiation therapy. Whether appearing independently or in combination, these impairments can severely impact activities of daily living and employment, resulting in functional disability and a decreased quality of life.
Physiotherapy has been shown to be effective in managing post-surgical musculoskeletal symptoms. For example, exercise rehabilitation has shown to result in clinically meaningful improvements in shoulder range of motion.

FATIGUE

Fatigue is a frequently reported yet poorly managed symptom reported by cancer patients. It is a complex symptom with various overlapping causes, some of which include anaemia, pain, sleep disturbance, thyroid dysfunction, and mood disorders. Physiotherapists can help their cancer patients manage fatigue through a focused history screening to determine the main contributors; by teaching the importance of planning and pacing their day; by designing a graduated exercise program to increase strength and energy levels; and through GP referral if the cause of their fatigue requires further investigation.

PAIN

Another complex symptom with multiple causes reported by cancer patients is pain, often requiring a multi-disciplinary approach to management. A physiotherapist’s role in pain management comes in the form of exercise prescription and acupuncture, both of which have been shown to be effective treatments for pain in this population.

THE IMPORTANCE OF PROMOTING AND PRESCRIBING PHYSICAL ACTIVITY

Engagement in regular physical activity is routinely stressed as a key preventive measure for many chronic health problems and breast cancer is no exception. However, it appears that historically healthcare professionals have been overly conservative with exercise prescription in cancer rehabilitation. The literature reports that many cancer survivors are not meeting standard exercise guidelines. Within breast cancer survivors, strength guidelines in particular are not being met. Today’s guidelines within cancer rehabilitation recommend the following:
Return to normal daily activities as soon as possible after diagnosis as early exercise interventions are showing to be more effective that delayed interventions. Exercise is safe during chemotherapy and radiation treatment and therefore patients should be encouraged to maintain their activity level during treatment as much as possible.
For substantial health benefits, patients should aim for at least 150 minutes of moderate aerobic exercise or 75 minutes of vigorous aerobic exercise per week. Strength training should be completed at least 2x/week. Gradual intensity weight-training is a safe way to improve upper limb strength without increasing the risk of lymphoedema.

PILATES AND BREAST CANCER

Clinical Pilates exercises taught by a physiotherapist are an excellent starting point for addressing any of the above listed health concerns post breast cancer treatment. With its focus on core engagement, precision and flow of movement, Pilates is an ideal exercise form for developing efficient movement; is safe for painful joints and muscles; and is easily adaptable to fit within pain, fatigue, and energy levels, as well as with upper extremity dysfunction. The focus on posture that Pilates involves also makes it a great option for addressing the postural changes that present post breast-cancer surgery. In addition, the diversity of Pilates allows it to be a challenging exercise option as strength and function improves post treatment.

SPECIAL CONSIDERATIONS

Be familiar with the common medical treatments for cancer and recognize that they are cancer-specific and are constantly changing. Keep in mind pre-existing health issues and fitness levels.
Adverse effects of cancer treatments may appear months or years after the completion of treatment and may present in multiple body systems.

Defending the Deadlift



Defending the Deadlift
By Matt Quinn
Introduction: 
Helen returns home from a routine trip to the grocery store with several bags. She decides to take the two heaviest bags into the house first. As she approaches her front door, she sets the bags down, retrieves her keys, and unlocks her front door. Helen then thinks about the safest way in which she can lift the bags off the ground. She first tightens her core and sets her back in tight extension. She then hinges at her hips, and lowers herself through slight knee flexion to bend over and grasp the bags. From here, Helen maintains the angle between her torso and hips, drives her feet into the ground and stands with fully extended knees and hips. Helen has just completed a safe, and successful deadlift.
One of the greatest risk factors for functional limitations and disabilities in middle-aged to older adults is muscular weakness (Volakis et al, 2015). Thus, a muscular strengthening component should be incorporated into fitness programs for individuals in this age range (“Why Strength Training”, 2010). Specifically, fitness instructors should aim to strengthen functional movement patterns that produce transferability into activities of daily living. Functional movements patterns are based on the way our bodies are designed to move, and they mimic the biomechanical demands life places upon us. Functional movements are multi-planar, multi joint, core to extremity movements. So, is the deadlift a functional movement? As we saw in the anecdote above, the deadlift presents itself in real life situations, but does it fit the other criteria? The answer is yes.
Multi-Planar
The deadlift requires motion or stability in all three planes. The first, and perhaps most obvious, is the sagittal plane. We move through the sagittal plane as we lift the bar up off the ground. The second plane of motion is the frontal plane, which represents side-to-side motion. As we lift the bar off the ground, we must stabilize the bar in a manner that allows both sides of the bar to be elevated off the floor simultaneously. A lack of stability in this plane would result in a lopsided bar as it is lifted. Finally, the deadlift also requires stability in the transverse plane. Stability in the transverse plane resists rotational movement of the bar (Robertson, 2012). If an individual were unstable in the transverse plan, they would twist or rotate as they lifted the bar.

Multi-Joint
The primary joints used for force production during the deadlift are the hips, knees and ankles. The deadlift requires activation in the ankle plantar flexors and knee extensors, but demands the most significant amount of activation from the hip extensors and knee flexors (Escamilla, 2000). To better understand movement at these joints, we will re-visit Helen’s task of lifting her grocery bags, starting from the ground and moving up.
Ankle plantar flexion is achieved primarily through activation of the gastrocnemius and soleus muscle groups. Plantar flexion is loosely defined as downward movement of the foot. A good example of plantar flexion is the “push off” motion of our foot during walking (Neptune, 2001). Although her feet would remain in contact with the ground, Helen would be using her plantar flexors to push into the ground and help initiate movement of the bar.
Knee flexion is achieved through activation of the muscles of the hamstring. Although her starting position is achieved mainly through hip flexion, slight knee flexion is required in order for Helen to position herself correctly. Ideally, the proper amount of knee flexion would place her shins perpendicular to the floor. This degree of knee flexion must be maintained as the bags are lifted until hip extension has been initiated.
The quadriceps muscles assist the gluteus maximus and hamstring in producing hip extension in addition to acting as the primary knee extensors (Frigo et al., 2010). As Helen lifts the bags off the floor, the contraction of her quadriceps would oppose the actions of the gluteus maximus and hamstring, thus stabilizing her knee position in slight flexion. With a fixed knee position, her gluteus maximus and hamstring can produce maximal hip extension once the bags have reached knee level. As she extends her hips and no longer requires knee flexion, the contraction of her quadriceps extends, or straightens, her knees from their previously flexed position.
Core to Extremity
Lifting any object off the floor, particularly a heavy one, requires both movement and stability of our core, depending upon which plane of movement we consider. When discussing core to extremity movement, it is important to understand that our body’s core is comprised of many muscle groups that work in conjunction to move or stabilize the core. While some core muscles may be acting to move the core in the sagittal plane, others will be activated in order to stabilize our torso in the frontal and transverse planes. Multiple layers of abdominal, oblique, spinal, and hip musculature work in conjunction to move and stabilize the core (Di Jensen, 2013) (Conneely, 2006). Movement with a stable core is imperative so that we ensure structural safety through efficient production and transfer of force from the core to our extremities (Bliss, 2005).
The deadlift is the epitome of a core to extremity movement, requiring significant activation of primary core muscles (Hamlyn, 2007). We use the core musculature to stabilize the spine while simultaneously moving the trunk towards the ground in order to reach the object. From this position, our stable core allows for transfer and production of force through our ankles, knees, hips, back, and arms as we safely elevate the object from the floor.

Conclusion
The deadlift is often criticized as a dangerous exercise that simply leads to injury, when in fact it is a basic human movement. While it is possible to injure yourself without proper instruction, the deadlift is a functional movement that our anatomy is built to execute. The deadlift is one of the most effective ways to train not only the posterior chain and core, but it also aids in the development of the assisting muscle groups, like the quadriceps. These muscle groups are of critical importance to everyone, whether it is an elite athlete looking to improve performance, or a father wishing to be able to safely lift his son off the ground. For these reasons, the deadlift should be an integral part of most, if not all physical activity regimens in order to best prepare individuals for the demands placed upon them by their activities of daily living.
