Can Exercise Help Relieve Shoulder Pain?

By Drs. Marc-Olivier Dubé, François Desmeules and Jean-Sébastien Roy

It is estimated that close to 70 per cent of the population will experience shoulder pain at some point in their lives.

This pain would not pose a problem if it disappeared as quickly as it appeared. Unfortunately, shoulder pain tends to persist over time. In half of patients, the pain lingers or reoccurs one year after its initial appearance. It can even persist for several years in some cases.

Approximately 70 per cent of shoulder pain episodes requiring consultation with a health-care provider can be identified as rotator cuff related shoulder pain. This refers to pain and loss of function in the shoulder, mainly during movements requiring the arm to be lifted. Although a number of effective options are available to patients, a third of them will not experience any significant improvement in their condition, regardless of the interventions used.

There are several possible reasons for this limited success. Exercise selection and some psychological and contextual characteristics specific to each individual have been identified as potential hypotheses.

As experts in the field of shoulder pain, we propose to shed light on the effectiveness of various interventions for the management of shoulder pain, and the role that some variables may play in the resolution of this pain.

Our research team therefore set out to find out:

1. Whether one type of exercise should be prioritized over another in the management of shoulder pain.

2. Whether the addition of exercises (the pet peeve of many people who consult a rehabilitation provider) lead to additional benefits compared with an intervention comprising only of education and advice to foster pain self-management.

3. Whether some psychological and contextual characteristics, such as participants’ expectations of the intervention effectiveness and pain self-efficacy, are associated with a better prognosis.

Pain self-efficacy is the level of confidence someone has in their ability to carry out their activities and achieve their goals despite pain.

What We Found

In our new study published in the British Journal of Sports Medicine, 123 people with shoulder pain lasting for more than three months were randomly assigned to one of three 12-week interventions:

1. Education

2. Education combined with motor control exercises

3. Education combined with strengthening exercises

Questionnaires were used to monitor changes in participants’ condition over time, particularly in terms of their pain and functional capacity.

Before the start of the intervention, we also used questionnaires to measure participants’ expectations of the effectiveness of the intervention they were about to receive, as well as their level of pain self-efficacy.

Education: Participants in this group received two sessions of education and advice with a physiotherapist. The information was about the shoulder and pain, and the advice included strategies for the self-management of their condition.

Participants were also told about the importance of being active and adopting a healthy lifestyle to optimize the management of persistent pain, including proper diet, hydration, stress management and sleep hygiene.

Finally, participants were asked to watch six short videos on these themes. Here’s one:

After viewing, they were asked to identify the aspects they felt were important and those that raised questions in order to discuss them with the physiotherapist.

Education combined with motor control exercises: Participants in this group completed a 12-week program that combined education with exercises.

The exercises included modifications in the way they performed their movements to enable them to move their arm with less pain. These modifications were integrated with exercises reproducing gestures involving the shoulder during daily activities.

Education combined with strengthening exercises: Participants in this group received the same education component, along with  a shoulder muscle strengthening program to be performed daily for 12 weeks.

At the end of the study, participants in all three groups showed improvements in pain and function. However, the addition of exercises (motor control or strengthening) to the education intervention did not lead to additional benefits.

People recruited into the study whose symptoms were considered resolved following the 12-week intervention had more positive expectations regarding the effectiveness of their intervention and had higher levels of pain self-efficacy.

Key Takeaways

Adding strengthening or motor control exercises to an educational intervention did not result in additional benefits compared to an approach based solely on education and advice. For some people with persistent shoulder pain, education and advice focusing on pain self-management may be sufficient to promote symptom resolution.

Exercise, in any form, remains a highly relevant intervention for shoulder pain management, as well as for maintaining independence and optimizing long-term health.

Participants’ pain self-efficacy and expectations of the effectiveness of the intervention they receive may play a role in the prognosis of their shoulder pain.

When you’re experiencing shoulder pain, it can be beneficial to temporarily reduce certain activities that can aggravate your pain. However, it’s important not to delay gradually reintegrating these activities into your daily routine.

The presence of pain, especially when it persists over time, is not necessarily a sign that your condition is deteriorating. It could simply indicate that the gestures or activities performed exceed the shoulder’s current ability to tolerate the load imposed on it.

In any case, don’t hesitate to consult a health professional, such as a physiotherapist, who will be able to help you “shoulder” the responsibility of managing your condition.

Lack of Education Is Fueling Overdose Crisis

By Pat Anson, PNN Editor

Anti-opioid activists have long claimed that excessive prescribing of opioids over a decade ago created an “epidemic of addiction” that lingers to this day. Once hooked on prescription opioids, patients turned to stronger and more lethal drugs — like heroin and illicit fentanyl — sending the overdose rate to record levels.

A large new study debunks that theory, showing that socioeconomic factors – particularly lack of education -- play a hidden but central role in the overdose crisis.

"The analysis shows that the opioid crisis increasingly has become a crisis involving Americans without any college education," said lead author David Powell, PhD, a senior economist at RAND, a nonprofit research organization. "The study suggests large and growing education disparities within all racial and ethnic groups --- disparities that have accelerated since the beginning of the COVID-19 pandemic."

Powell looked at data from the National Vital Statistics System from 2000 to 2021, and identified over 912,000 fatal overdoses for which there was education information on the people who died.

His findings, published in JAMA Health Forum, show that overdose deaths increased sharply among Americans without a college education and nearly doubled in recent years for those who don’t have a high school diploma. The findings are notable because they came during a period when per capita consumption of prescription opioids plummeted, sinking to levels last seen in 2000.

For people with no college education, the overdose death rate increased from 12 deaths per 100,000 individuals in 2000 to 82 deaths per 100,000 in 2021. That rate is sharply higher than Americans who have some college education. In 2000, their overdose rate was 4.6 deaths per 100,000 people, which rose to 18.6 deaths per 100,000 in 2021.

Trends in Overdose Deaths by Educational Attainment

Powell is not the first researcher to link socioeconomic factors to overdose deaths. The so-called “deaths of despair” were first reported in 2015 by Princeton researchers Angus Deaton and Anne Case, who found that economic, social and emotional stress were major factors in the reduced life expectancy of middle-aged white Americans, who increasingly turned to substance abuse to dull their physical and emotional pain.

Education plays a significant role in socioeconomic status. People without college degrees are more likely to have blue-collar jobs requiring manual labor, which raise the risk of work-related injuries and conditions such as arthritis. One recent study found that people who did not finish high school in West Virginia, Arkansas and Alabama were three times more likely to have joint pain compared to those with bachelor degrees in California, Nevada and Utah.

“Overall, the analysis suggests that the opioid crisis has increasingly become a crisis disproportionately impacting those without any college education. Research is needed to understand the driving forces behind this gradient, such as isolating the independent roles of differences in income, employment, family composition, health care access, and other factors,” said Powell.

“Overdose death rates grew during the COVID-19 pandemic, and the education gradient increased further, although it is unclear what role the pandemic had relative to changes in fentanyl penetration in illicit drug markets and other factors.”

Powell says education merits further attention in understanding how and why the opioid crisis continues to intensify and lower U.S. life-expectancy.

Arthritis Pain Varies Widely Across States

By Pat Anson, PNN Editor

People living in West Virginia are three times more likely to have moderate or severe joint pain from arthritis than those in Minnesota, according to a comprehensive new study that highlights how disparities in education and access to social services contribute to chronic pain.

“Very little research has examined the geography of chronic pain, and virtually none has examined the role of state-level policies in shaping pain prevalence,” says co-author Hanna Grol-Prokopczyk, PhD, an associate professor of sociology at the University of Buffalo. “We were excited to identify state characteristics that reduce residents’ risk of pain.”

Grol-Prokopczyk and her colleagues looked at data for over 400,000 adults who participated in the 2017 Behavioral Risk Factor Surveillance System, along with data from all 50 states on social assistance and anti-poverty programs such as the Earned Income Tax Credit, Medicaid and Supplemental Nutrition Assistance Program (SNAP), more commonly known as food stamps.

Their findings, published in the journal PAIN,  show the risk of joint pain was significantly higher in states in Appalachia, the Mississippi Valley and the South, compared to states in the Upper Midwest and West.

Nearly one in four adults in West Virginia (23.1%), Alabama (21.6%) and Arkansas (21.4%) had moderate to severe joint pain. States with the lowest risk of joint pain are Minnesota (6.9%), Hawaii (7.5%) and Utah (7.7%).

Digging deeper into the data, researchers found that educational disparities are also associated with pain frequency. People who did not complete high school in West Virginia (31.1%), Arkansas (29.7%) and Alabama (28.3%) were far more likely to have joint pain compared to those with bachelor degrees in California (8.8%), Nevada (9.8%) and Utah (10.1%).

People with less education are more likely to have blue-collar jobs requiring manual labor that may contribute to joint pain. They also have lower incomes and less access to healthcare.

“Education can function as a ‘personal firewall’ that protects more highly educated people from undesirable state-level contexts, while increasing the vulnerability of less educated individuals,” said first author Rui Huang, a sociology PhD student in the UB College of Arts and Sciences.

Researchers also found that states with higher levels of SNAP benefits, social support and community health services had lower levels of pain frequency.

“The increase in the generosity of SNAP benefits could potentially alleviate pain by promoting healthier eating habits and alleviating the life stress associated with food insecurity,” says Huang. “Social factors such as conflict, isolation and devaluation are also among the ‘social threats’ that can lead to physical reactions such as inflammation and immune system changes.”

Previous studies at the University of Buffalo have found that gender, poverty and education play a role in pain frequency and that the overall prevalence of pain is increasing in the United States, affecting virtually every age group, sex, ethnicity and demographic.

Who Gets Rx Opioids and Who Doesn't

By Pat Anson, PNN Editor

Although opioid prescriptions in the U.S. have fallen by 40% since 2011 and now stand at their lowest level in 20 years, it’s still common to see claims that opioids are “overprescribed.”  

“Doctors And Dentists Still Flooding U.S. With Opioid Prescriptions” was the headline used by National Public Radio for an in-depth look at opioid prescribing practices.

“Public data, including new government studies and reports in medical literature, shows enough prescriptions are being written each year for half of all Americans to have one,” NPR reported in 2020. “Patients still receive more than twice the volume of opioids considered normal.”

A new study by the CDC gives some much-needed context to the myth that opioid prescriptions are flooding America. Over the past decade, the so-called flood has turned into a trickle for the vast majority of chronic pain patients – the people most in need of effective analgesia.  

The CDC study, which is based on the 2019 National Health Survey, found that only about one in five chronic pain patients – 22.1 percent – had used a prescription opioid in the past 3 months. In other words, it is “normal” for pain patients not to get opioids. 

A previous study that looked at opioid prescriptions in 2010 found that 36.4 percent of patients with chronic non-cancer pain were prescribed an opioid.  While there are differences in methodology between the two studies, the data seems to confirm that there has been a shift in prescribing practices over the past decade. Pain patients are significantly less likely to get an opioid prescription today than they were in 2010.

The new CDC study is also the first to take a deep dive into the demographic and socioeconomic characteristics of opioid recipients -- how age, sex, insurance, income, education and other factors make patients more or less likely to take opioid medication. Considering how much attention has been paid to opioid prescribing over the last decade, it’s surprising no one has looked into this before.

Researchers found that you are more likely to use prescription opioids if you are female, aged 45-64, unemployed, live in a rural area, and a Medicaid or Medicare beneficiary.  Being Black, White, a non-veteran, and living below the federal poverty level also makes you more likely to take a prescription opioid.

Conversely, you are less likely to take prescription opioids if you are male, aged 18-29, employed, a military veteran, privately insured, and live in a household at least 200% above the federal poverty level. Being Hispanic, uninsured, having a college degree, and living in a large metropolitan area also makes you less likely to use opioid medication.

The CDC study did not look what type of chronic pain condition a patient had or how long they had it. It’s possible the condition itself led to someone becoming unemployed, disabled and poor, or that some other factor is at work. Military veterans, for example, have high rates of chronic pain but get fewer prescriptions because the Veterans Administration strongly discourages the use of opioids.

Researchers also relied on patient “self reports” and did not compare their answers with prescription records. Given the stigma association with opioids, it’s possible some patients may have answered “no” to opioid use, when in fact they used the drugs.

No study is without limitations, but this one shows some clear disparities between who uses opioid prescriptions and who does not. Poverty, lack of education and unemployment may have more to do with pain, drug use and “overprescribing” than policy makers and anti-opioid zealots have been willing to admit.

Sex, Poverty and Education Linked to Chronic Pain

By Pat Anson, Editor

If you are female, poor and never finished high school, you are much more likely to suffer from chronic pain than other Americans, according to a new study published in the journal Pain.

“Women, the less educated, and the less wealthy experience not only more pain, but also more severe pain, as well as greater disability, said Hanna Grol-Prokopczyk, an assistant professor of sociology at the University of Buffalo.

Grol-Prokopczyk studied over 12 years of data from nearly 20,000 Americans aged 51 and over, who participated in the national Health and Retirement Study from 1998 to 2010.

Her research uncovered some unexpected findings about chronic pain in the United States.

She found that the severity and frequency of pain is increasing in older adults. People who were in their 60’s in 2010 reported more pain than people who were in their 60’s in 1998.

“There are a lot of pressures right now to reduce opioid prescription,” says Grol-Prokopczyk. “In part, this study should be a reminder that many people are legitimately suffering from pain. Health care providers shouldn’t assume that someone who shows up in their office complaining of pain is just trying to get an opioid prescription.

“We have to remember that pain is a legitimate and widespread problem,” she added.

The study is among the first to measure chronic pain by degree. Participants were asked whether their pain was mild, moderate or severe, and if they were “often troubled with pain.” Participants were followed for over 12 years, as opposed to most studies that follow patients over a much shorter period.

“I found that people with lower levels of education and wealth don’t just have more pain, they also have more severe pain,” she says. “I also looked at pain-related disability, meaning that pain is interfering with the ability to do normal work or household activities.  And again, people with less wealth and education are more likely to experience this disability.”

About one out of every four people who didn’t finish high school said their pain was severe, while only 10 percent of those with college graduate degrees did so.

About 8 percent of African Americans and Hispanics said their pain was severe, compared to about 5 percent of whites.

“If you’re looking at all pain – mild, moderate and severe combined – you do see a difference across socioeconomic groups. And other studies have shown that.  But if you look at the most severe pain, which happens to be the pain most associated with disability and death, then the socioeconomically disadvantaged are much, much more likely to experience it,” said Grol-Prokopczyk.

More research needs to be done to understand why pain is so unequally distributed in the population, and Grol-Prokopczyk says it’s critical to keep the high burden of pain in mind as the nation grapples with an overdose epidemic.

“We don’t have particularly good treatments for chronic pain. If opioids are to some extent being taken off the table, it becomes even more important to find other ways of addressing this big public health problem,” she said. “If we as a society decide that opioid analgesics are often too high risk as a treatment for chronic pain, then we need to invest in other effective treatments for chronic pain, and/or figure out how to prevent it in the first place.”
