You may have heard about people who got a COVID-19 infection and have symptoms for weeks or months after. This is now referred to as Long COVID. In this post we’re going to dive into what Long COVID is, what the symptoms are and who it affects. Next month we’ll talk about strategies that are helping people with Long COVID and where physical therapy fits in. Let’s get started.
What is Long COVID?
Long COVID is generally defined as ongoing signs or symptoms lasting 12 weeks or more after a COVID-19 infection.
What is it like?
Like all things COVID-19, we don’t fully understand Long COVID and new information is being discovered all the time. Long COVID tends to involve more than one system and currently has a list of over 200 possible symptoms.
The most common are:
1. Fatigue
2. Post-exertional symptom exacerbation (PESE)
3. Problems with memory or concentration, often referred to as “brain fog”
Other common symptoms are shortness or breath, chest pain or tightness, insomnia, muscle or joint pain, depression/anxiety, and stomach problems like stomach aches, loss of appetite or diarrhea.
What’s the fatigue like? Does rest help?
Long COVID fatigue is an extreme exhaustion that isn’t relieved by rest or sleep. It’s not fatigue after some physically demanding task. People experience exhaustion for no obvious reason. The fatigue is so severe that it impacts the ability to complete daily tasks.
What about this PESE thing?
Post-exertional symptom exacerbation is a disabling and often delayed exhaustion disproportionate to the effort made. Patients are referring to this as a “crash”. PESE is very common in people suffering from Long COVID. 75% of people who have Long COVID have PESE after 6 months. The activity that brings on the crash is something that the person could easily tolerate before their COVID-19 infection. Things like taking a shower, walking, attending a social activity, or even being in a high sensory environment with flashing lights and loud noises may all now trigger a crash.
Who does Long COVID affect?
This is difficult to answer. We still don’t understand what causes some people to have symptoms long after their initial infection. What we do know is that about 25% of people who get COVID have symptoms that last at least a month. Around 10% of the people who get the virus will experience Long COVID. Long COVID isn’t related to how severe your initial symptoms were, or if you were hospitalized. It also doesn’t appear to be related to your previous health as it affects children and people who were previously fit and healthy.
Now that you know what Long COVID is, in our next installment we’ll talk about what’s being done for it and how physical therapy helps.
What is Post-Intensive Care Syndrome and What Does PT Have To Do With It?
When you think about a person going into intensive care, you probably picture someone who’s very ill and likely fighting for their life. They may be on a ventilator or other equipment that’s keeping them alive. When you’re in that situation, surviving would be a win. But what happens after these people survive? Do they recover and go back to life as it was? What’s the road to recovery look like?
Fortunately, medical advances have led to higher survival rates for people who end up in intensive care units – it’s now between 71% and 90%, which is great. But, survival is not the end goal, and getting out of the ICU is not the end of the battle. Many patients show significant losses of physical, mental and cognitive abilities after discharge. It makes sense – if you don’t use it, you lose it! This cluster of problems is called Post-Intensive Care Syndrome or PICS.
PICS is now recognized as a public health burden. Interventions against PICS need to start in the ICU. Then they need to continue after discharge.
Physical declines often include significant losses of strength, endurance, and mobility. These can lead to serious difficulty completing basic daily tasks like getting to the bathroom, preparing a meal, or walking to the mailbox. This may keep some people from returning home. For others, it means they need a caregiver to safely return to their previous setting. 50% of ICU survivors have limitations in daily activities 1 year later, so this is a serious and long-lasting problem.
Mental health is also a very real concern for ICU survivors. They show significant rates of depression – the mean is 28%. 24% of survivors have anxiety and 21% report PTSD. Again, these conditions have a real impact on the quality of life after leaving the ICU.
Last, declines in cognitive abilities are very common in ICU survivors. 77% have cognitive impairments at 3 months post-discharge and 71% have impairments 1 year out. Cognitive issues after discharge can include poor memory, slower thinking, problems making decisions, or difficulty concentrating.
Physical therapists play a significant role in the fight against PICS. PT typically begins while the patient is in ICU, focusing on getting the patient up and walking early. Patients begin a progressive exercise program as soon as it’s safe for them. We expect a rise in PICS due to the number of people who COVID-19 has put into critical care and/or on a ventilator.
While we can’t prevent every problem that critical illness causes, recognizing the losses that remain after discharge from the ICU is an important step. Physical therapists play an important role in combating the effects of PICS and helping people return to higher-quality lives.
Physical Therapy is a Tree With Many Branches
Starting a career in physical therapy is like climbing a tree. Everyone starts with the same trunk, but pretty quickly, you have to make some decisions about which way you’re going to go. What kind of people do you want to work with? Where do you want to practice? And how far up the tree do you want to climb? You’ll get to grow professionally – learning more, getting better clinically, and maybe even improving your sales and business skills, but that’s not all. Physical therapy gives you a chance to grow personally too.
Pick your people
You can pick the type of people you want to work with – sports physical therapists work with athletes, helping them recover from injuries and improve performance through exercise and hands-on techniques. Geriatric physical therapists work with elderly patients on mobility problems, pain or managing chronic conditions. Pediatric physical therapists work with infants and children providing developmental assessments and helping them improve their gross motor skills.
Pick your place
You can also pick where you work – there are physical therapy jobs in nursing homes, hospitals, outpatient clinics and schools. Physical therapists provide care wherever people need it. So far, we’ve only mentioned the more common places you’ll find PTs – if you want to specialize further, you may find yourself working only in the ICU with critical care patients, in a factory doing industrial rehabilitation and ergonomics, in a women’s health clinic, or even working in a preventative, public health role.
Grow professionally
Most physical therapy careers start in a general role, working with all types of different patients. If you work in a large health system, you may even rotate between settings. But as you find the type of people you like to work with and the setting you prefer, you have the option to improve your skills and focus on a specialty area of practice. Again, you have lots of options on how to do this. You could:
● Take an internship position or join a fellowship program
● Attend workshops or conferences
● Read journals and textbooks
● Collaborate with your colleagues and mentors
● Take courses in other areas of medicine
● Study abroad or take courses online
Grow personally
Your clinical skills aren’t the only thing a career in physical therapy can grow though – you’ll grow personally as well. You have to learn to have compassion and empathy when you work with ill or injured people. You have to work as a part of a team. You need sales skills – most people aren’t going to want to make changes in their routines, or do the exercises you prescribe at home. You’ll learn to work with people who have different opinions and different viewpoints from all kinds of cultures and backgrounds.
You may also have a chance to improve your business skills. You could advance out of the clinical setting and into a management role. Some PTs start their own practices, or a company in a field related to physical therapy like wellness, performance, injury prevention or population health for large corporations.
Wherever you start in physical therapy, you’ll have a lot of options on where you end up. Chances are you’ll explore more than one branch of the physical therapy tree. That’s OK, having the chance to grow and change is part of what makes PT so exciting!
Working in physical therapy has benefits that extend beyond the clinic
Stories about hiring difficulties are all over the news right and physical therapy clinics haven’t been left out. An aging population with more chronic diseases has been pushing up the need for physical therapy for years. The pandemic has accelerated the problem. Clinics aren’t only looking for PTs and PTAs either. Finding the right people to fill roles in billing, administrative and tech roles is difficult too. Many clinics also employ people like nutritionists, athletic trainers and fitness professionals. If you’re looking for a new place to work or a change in career, a PT clinic might be a great setting for you. Here’s a few reasons why:
Build relationships
Physical therapy is unique in the world of healthcare because of the time that patients spend in the clinic. People often come in 2 to 3 times a week for anywhere from a few weeks to several months depending on what they’re coming in for.
When people spend that much time together, it’s easy for great relationships to form. Often these relationships end up lasting a lifetime and have benefits that extend outside the clinic. Having a large and diverse network is never a bad thing and a PT clinic is a great place to build one.
Make a difference
Physical therapists work with people who have injuries or disabilities that affect their mobility, as well as those who have chronic illnesses like heart disease or diabetes. They help people heal faster and get them back to normal life, with a focus on function. That means PTs want to help people get back to meaningful things like going to work, recreational activities, hobbies, or playing with grandkids. Being able to return to things like that means a lot more to patients than lowering their blood pressure or improving their lab values. And it feels good to be a part of making that happen.
If you’ve never considered working in a PT clinic, it might be right for you. It’s rewarding and a great way to build relationships, become valuable in the community, and make a difference in people’s lives.
Returning to Activity After a Pandemic
During the COVID-19 pandemic, activity levels dropped for a lot of people. Between stay at home orders, gym closures and working from home, people became more sedentary. On top of that, there were shortages of equipment like dumbbells and bicycles, making staying active at home difficult even if you wanted to.
But this summer, things look different; vaccines are widely available, restrictions are loosening and people are looking to get active and enjoy the warm weather. That’s all good news, but if you had a long break from activity, your body might not be ready to jump right back in. Here are a few tips to help you get more active without getting hurt:
Start slow
● If you’re a runner, think about a walk to run program
● If you’re a weight lifter, start with lighter weights and less reps.
● Whatever your activity of choice is, start with short periods of activity and gradually work your way back up.
Warm up and cool down
Warming up gets your heart and lungs ramped up and prepares your muscles and tendons for the increase in activity about to come. Include some light cardio like jogging, calisthenics, or cycling, followed by active stretching like butt kicks, high knees, or yoga.
Cooling down transitions your body back to a lower state of stress – it brings your heart rate and breathing down, decreases blood flow to your muscles and back to places like your digestive system, and helps you relax. It’s also a great place for static stretches if you need some work on your flexibility.
Take a day off
Rest days let your body recover and keep you from getting burned out. Not enough exercise isn’t good for you, but too much of a good thing can cause problems too.
Watch for early signs of injury
Some soreness for a few days after activity is normal, especially if you’ve had a long break. But there are a few common issues to watch out for as you return to activity:
● Swelling or bruising
● Joint pain, especially in the knees or shoulders
● Foot pain, which could be a sign of plantar fasciitis
● Muscle strains – particularly common in the hamstrings
● Sprains – most common in the ankle
Any of these issues justifies a call to your physical therapist. Getting checked out early can prevent an injury that derails your attempt to return to activity. PTs see all of the issues just mentioned on a regular basis and can help safely guide you back into a more active lifestyle.
Physical Therapy Isn’t Just For Pain. It Can Keep You Healthy For Life.
You know that physical activity is good for you. The benefits are well researched and the list is impressive.
Here’s just a sampling:
● Releases endorphins to make you feel good and fight depression
● Helps control weight
● Prevents diseases like stroke, diabetes and some forms of cancer
● Improves sleep
● Helps you live longer
Recent studies even show that physical activity strengthens your immune system, with a protective effect against COVID, and that staying active through middle age protects your brain as you age.
Physical activity is a wonder drug. If it was a pill, you’d buy it and take it every day. But even though activity is free, less than 25% of Americans meet the CDC recommendations for activity. We clearly need help.
Physical Therapists Are The Experts in Human Movement
To be active, you need to be able to move. Physical Therapists do more than help you recover from surgeries or major injuries. They are the experts in human movement. Sure, you could see a strength coach to lift weights, hire a personal trainer, go to a yoga class to work on your flexibility and balance, and see a chiropractor for adjustments. But that seems like a lot of people when a PT can help you with all of these things and more. Nobody knows more about human movement or looks at your health the same way a PT does. Your PT can help you with every aspect of movement including strength, range of motion, flexibility, endurance, balance and coordination.
As medical professionals they can help you with injuries or other issues. Your PT can work with your doctor to help use activity to manage things like diabetes, cholesterol levels or blood pressure instead of prescriptions. Your PT is also trained to work with people of all ages, so you can develop a long-term relationship and they can continue to adjust and modify your routine as you age or your goals change.
Stay Healthy For Life
Staying active has a long list of benefits both now and in the future. But chances are you’re not moving enough to make the most of those benefits. Most people need help. Physical therapists are the most qualified professional in existence to help keep you healthy now and in the future. So don’t think of your PT as someone you see when you need help with pain or an injury. Think of them as your partner and coach working to help you stay healthy for life.
Want to Stay Healthy? Move More.
COVID has certainly made the importance of health very clear and we have all seen how quickly
things can change with an illness. While COVID is currently front and center in most people’s
thoughts, it isn’t the only thing out there that can change your life. Heart disease, diabetes,
strokes and cancer can all be devastating too.
Movement offers a defense
If you’re looking to be more resilient and defend against these things, physical activity can do it.
The dangers of being sedentary are well known and documented in the research. Excessive
sitting and sedentary time have even been called the new smoking. For many of us, sitting and
being inactive is part of our jobs. However, research has shown that getting in enough
movement can counteract the negative effects of being sedentary.
A large study done in the U.K. found no association between the amount of time people spent
sedentary and their chances of illness. But the authors didn’t conclude that being sedentary is
OK. Instead, they felt their findings were likely “attributable to a protective effect of the high
volumes of daily walking.” The study was conducted in London, where people tend to spend
much more time walking or standing than average. The people in the study had daily walking
times that were over double the average amount reported in the U.K.
Physical Therapists Are Unequaled Experts in Human Movement
While walking was the activity in this particular study, other research has shown that all kinds
of movement can help protect your health. If you’re looking to get those protective benefits for
yourself you could choose to walk, bike, lift weights, dance or garden. If you’re not moving as
much or as well as you’d like, see your physical therapist. PTs are the most qualified
professionals on the planet to help you move better and allow you to stay healthy and enjoy
life. From designing a program to get you started or moving more to helping you recover from
an injury, your PT is the right person to look to for help.
Will COVID-19 Change the Typical PT Patient?
People usually see a physical therapist for pain or loss of function. Think of the person who has
back pain, the injured athlete or the person who’s had a stroke. They all want to improve how
they move and complete tasks. Now, there is good reason to wonder if physical therapists will
start seeing more people who are not in pain or having difficulty moving. Why would these
people come to a PT? To improve their overall health and wellness.
There is strong evidence suggesting that movement is a valuable predictor of future health
and resilience against disease. Physical therapists are movement specialists, so taking
advantage of their expertise makes sense if your goal is to become healthier and live longer.
Here are some examples of the power of movement when it comes to predicting future health:
Gait Velocity
Gait velocity is how fast you walk. Studies have shown that if your typical walking speed is over
1 m/s or 3.3 ft/s, you’re likely able to complete typical daily activities independently. You’re also
less likely to be hospitalized and less likely to have adverse events like falls.
If you’d like to test yourself, measure out a straight, flat course to walk between 10′ and 30′ long.
You’ll also need 5′ or so at the beginning and the end for acceleration and deceleration. Walk
the course at your typical speed and divide the length of the course by how long it took you to
walk it (distance/time). That’s your gait velocity.
Get On and Off the Floor
A series of studies suggest that if you can go from standing to sitting on the floor and back to
standing without using your hands, you’re a lot less likely to die than someone who can’t. It’s
called the sitting-rising test. Here’s how it works:
You start standing, and without support you sit down on the floor, then stand back up. You start
with a score of 10. Every time you put a hand, knee, forearm or the side of your leg on the floor
you lose 1 point. Putting a hand on your knee or thigh to help also costs a point. In a sample of
over 2,000 people, they found that scoring less than 8 points made you twice as likely to die in
the next 6 years when compared to people who scored higher. Score 3 or less and you’re 5
times more likely to die in the same period. Overall, each point in the test is worth a 21%
decrease in mortality from all causes.
Notice that both gait velocity and the sitting-rising test aren’t specific to any one thing. The risk
of hospitalization in the gait velocity studies was hospitalization for any reason. Death in the
sitting-rising studies was death from anything. So while we know that exercise and healthy
lifestyle reduce your risk of specific diseases like heart disease or diabetes, it appears that
being able to move may provide much more wide ranging protection than we previously thought.
Insurers Are Moving From “Sick-care” to “Well-care”
TRICARE has decided to waive the cost-sharing requirement of up to three visits to a physical
therapist for low back pain. They’ve said that the goal is to encourage more use of “high-value”
treatments for low back pain. Understanding what they mean by “high-value” vs “low-value”
treatment can help us see the direction healthcare payers are moving and how physical therapy
is a part of that.
TRICARE tells us in their summary of this demonstration what they mean by high and low-value
care: “Increasing the value of health care refers to improving patients’ quality of care and
outcomes, improving patients’ access to care, and reducing overall costs of care. In contrast,
low-value care refers to interventions that: are not proven to benefit patients; may harm patients;
result in unnecessary costs; or waste health care resources.”
High-value care
High-value care leads to better outcomes, is easy to access and is cheaper for both patients
and insurers. We already know that physical therapy fits into this category, but if we look at
other things that fall into this category, a larger theme starts to emerge. In 2017 the American
College of Physicians released guidelines for treating low back pain that have been widely
endorsed. Initial treatment recommendations include exercise, stretching, tai chi, yoga,
progressive relaxation, heat or ice, cognitive behavioral therapy, and motor control exercise.
These are all active treatments, where the practitioner and the patient are working together to
improve. This is “well care” or “let me help you get better.”
Low-value care
In contrast, low-value care tends to be “sick care” where the patient is a passive participant and
the practitioner is saying “let me make you better.” TRICARE puts imaging before six weeks
without red flag symptoms, surgery for non-specific low back pain, opioids as the first or secondline treatment, and bedrest in the low-value category. We would also place spinal injections in
this category for most people. They’re expensive, only offer temporary relief, usually have a long
wait before they’re available and include the risk of serious infection and damage to surrounding
soft tissues like skin, cartilage, and ligaments.
This isn’t to say that imaging, surgery, or injections are always bad. For a small percentage of
people with low back pain, they’re the right thing. But, most people should start with treatments
that have the best outcomes for the lowest cost. If those treatments tend to focus on
empowering the person in pain to actively participate in their care rather than making them
dependent on someone to “heal” them, that’s even better. Physical therapists have known this
and have been providing care that fits this model for years. TRICARE’s demonstration that
waives cost-sharing clearly shows that insurers are recognizing the value of this type of care
and that they are actively moving in this direction.
TRICARE Thinks PT is so Valuable, They’re Covering the Whole Cost!
TRICARE, one of the nation’s largest insurers wants their members to get physical therapy for
back pain. They think that treating back pain with PT is so important that they’re willing to waive
the cost to their members. That’s a huge deal. When’s the last time you remember an insurance
company covering the entire cost of anything? Let’s dive into back pain treatments and see why
TRICARE likes PT so much.
You probably already know that back pain is a common problem. What you might not know is
that the medical system isn’t very good at treating it. “Non-drug treatments like physical therapy”
are the first treatment recommended for back pain. Unfortunately, many providers don’t follow
this and treatments are often recommended based on opinion rather than research. This means
insurance companies and patients often end up spending a lot of money for outcomes that are
less than stellar.
Here’s how it usually goes: You go see your doctor with back pain. They might give you
medication, recommend rest, some stretches, send you for x-rays or an MRI. Next will likely be
a referral to a specialist like an orthopedic surgeon. Chances are you won’t be having surgery
right away, so the specialist will either refer you to PT, or back to your PCP where you’ll end up
with a PT referral. The path will look different for each person, but the end result is usually the
same – multiple failed treatments, imaging you probably didn’t need and a delay of weeks or
months to get to a physical therapist.
Multiple large studies have looked at the effects of early physical therapy on low back pain with
impressive results. One of them was done in 2006 in Seattle by Virginia Mason Health Center.
They teamed up with Aetna and Starbucks to send workers with back pain to see both a
physical therapist and physician for their first treatment. Use of MRI dropped by 1/3, people got
better faster, missed less work and were more satisfied with their care. The cost savings was so
great, that Virgina Mason was losing money on treating back pain and Aetna ended up paying
them more for PT treatments because Aetna was saving so much money.
Intel ran a similar program with their employees, getting people with back pain to a PT within 48
hours. Previously it took about 19 days for people to get to a PT. With the earlier access,
patients completed their care in 21 days, compared with 52 days previously and costs dropped
between 10 and 30%. Intel also found more satisfaction with care and a faster return to work.
The data is out there that proves physical therapy is the cheapest and most effective treatment
for most people’s low back pain. It’s clear that people with back pain should start treatment with
their physical therapist, but most don’t. TRICARE’s pilot program that waives copays for up to
three PT visits aims to change that. If successful it will lead to lower costs for both TRICARE
and their members while delivering better outcomes in less time.
