Plyometric exercises are a series of drills that utilize explosive forces in functional or sport specific patterns that help you develop strength, power, and coordination. This type of exercise challenges demands of the stretch shortening cycle, which involves an eccentric contraction of a muscle followed by an immediate concentric contraction of that same muscle. The stretch shortening cycle is significantly hindered following injury and/or surgery, as muscles lack the ability to attenuate eccentric loading and preserve the energy needed to complete powerful movements in series.
In physical therapy the stretch shortening cycle and eccentric control is typically evaluated through the single hop test, triple hop test, crossover hop test and 6 meter timed hop test. It is recommended that an individual has to score >90% on the tests to have a reduced risk of reinjury when they return to their sport. These tests are most often used after rehab following ACL reconstruction. Although these tests are commonly used in PT, patients are often discharged after achieving >90% on these tests and acquire another injury shortly after their return to sport. This is a common occurrence because patients are trained to pass these return to sport tests and measures; however, the patient is truly not trained to return to their specific sport.
With the concepts of the stretch shortening cycle explained above it is essential to challenge a patient maximally through the stretch shortening cycle in order to ensure that a patient can appropriately absorb and produce the forces needed to compete in their sport without reinjury. It is also important to assess the psychological readiness and fear avoidance for a patient to return to sport. This can be easily evaluated by giving patients the Injury-Psychological Readiness to Return to Sport Scale (I-PRRS) and evaluating the progression of this questionnaire throughout the plan of care. Below are exercise examples to challenge the patient maximally throughout the stretch shortening cycle.
Staying healthy is likely at the top of your list almost every winter. But this year, in the midst of a pandemic, it may be even more of a concern than usual. You might wonder: should you be taking special supplements to boost your immune system, or investing in cleaning devices to zap germs? While the viral threats may be different from usual this year, the truth is that you should still be using many of the same strategies that you use in a typical year. Below are five of his top tips that can help you keep yourself and your loved ones safe.
Clean your hands
Practicing good hand hygiene. Washing with simple soap and water, and using an alcohol-based hand sanitizer when soap and water aren’t available, can help keep you from transporting germs from an infected surface to your eyes, nose, or mouth. Also, be sure to follow local and state recommendations, which may include additional strategies such as wearing a mask and avoiding large gatherings, particularly indoors.
Eat healthy and exercise
Prime your immune system to effectively fight disease by keeping your body healthy. Follow a nutrient-rich diet that includes lots of fruits, vegetables, and whole grains. Also, exercise regularly, and get enough sleep. “Being in good health helps us to resist infectious diseases.
Don’t skip doctor visits
Some people may fear getting exposed to illness, so they decide to avoid routine screenings and doctor’s appointments. But they may be putting themselves at higher risk by doing so. “Doctors’ offices are now equipped for routine visits in a coordinated and safe manner.” Whether you show up in person or visit via video, it’s important to check in periodically with your doctor. Screenings are important for maintaining overall health and catching potential problems early, when they are most treatable.
Vaccinations aren’t only for kids; they’re a proven means of boosting your immune system to protect against certain viruses and other infectious agents. Although COVID-19 has taken center stage recently, don’t forget about traditional threats, such as the flu. Getting your annual flu shot is essential this year. Adults should also make certain that they are up to date on their tetanus shot, which should be given every 10 years, and consider getting the newer shingles vaccine, called Shingrix, which is recommended to everyone over age 50. It’s designed to prevent the virus that causes chickenpox (which remains in the body even after the infection has cleared) from reactivating and causing the painful shingles rash and other symptoms. Adults over age 65 may also want to consider the pneumococcal vaccine to protect against a type of pneumonia unrelated to COVID-19. And stay tuned for news about about the vaccine that could protect against COVID-19.
A host of products on the market claim to protect you from germs — “self-cleaning” surfaces, ultraviolet (UV) lights, and even substances you’re supposed to ingest, says Starnbach. Many of these items have some scientific basis, but it’s often a big leap from that basic science to the final product, he says. For example, one type of “self-cleaning” surface claims to use crystals to kill germs. While those crystals might indeed kill germs in a laboratory, it’s not at all clear that they work the same way to kill germs in a real-life setting, says Starnbach. So, there is much room for skepticism.
The same is true for UV lights. UV light at certain wavelengths definitely has the ability to kill bacteria and viruses; however, those specific wavelengths are also dangerous to human eyes and skin. Plus, in order to work, the light has to come into contact with the virus. Most viruses you pick up in the environment are contained in droplets of mucus, he says. UV light typically can’t penetrate the mucus, which means it can’t deactivate the virus. Even something as simple as dirt can cast shadows that keep the light from reaching its target. Fogging devices run into the same problem. They can really disinfect only if the surface is cleaned first. Ultimately, the best way to keep your environment germ-free is to wipe surfaces clean and then disinfect to deactivate any virus. You don’t need any special devices, just a rag and some generic cleaning products

COVID 19 has definitely changed everyone’s ideals of work life balance. As a society we are sitting now more than ever. Neck pain is a common condition that can occur due to a sedentary lifestyle. At ARSO, we see many of our patients coming in with neck pain due to poor ergonomic and biomechanical set-ups at their desks. In this blog, we’ll talk about some ways to prevent neck pain during the pandemic and what to do if you have an episode of neck pain.
So what is neck pain and what causes it?
Neck pain can be dull, achy, sharp, or boring pain that is in the muscles at the top of where the head and neck meet and can go all the way into your shoulders.
How can physical therapy help?
A physical therapist is an expert in ergonomics and movement. They can help you with your desk setup, help identify muscle weakness that may be causing your pain, give you exercises to improve your range of motion and posture, apply modalities to help break the acute pain cycle, and use manual therapy techniques to address any restrictions in your joints.
How should you set up your desk to prevent neck pain?
What to do if you have neck pain?
Do not panic. Pain does not necessarily mean that something is structurally wrong or “out of place”.
Please give us a call to schedule an appointment. We are currently offering both in-person and telehealth appointments. Maryland is a Direct Access state, so a physician’s referral is not necessary for an initial evaluation.
Seek immediate emergency care:
If your neck pain is 10/10 with pain into your arms
If you hit your head
If you have neck pain and dizziness, lightheadedness, double vision, trouble swallowing, nausea, or episodes of fainting.
If you have neck and sudden clumsiness in your feet
It is estimated that about 100 million people in America are living with chronic pain. Chronic pain can interfere with your day-to-day work and recreational activities, and it may have a profound effect on your ability to concentrate, relax, and enjoy life.
There are a multitude of treatments available for chronic pain: medication, massage, exercise, acupuncture, and a host of other treatments. Physical Therapy (PT) for chronic pain is also an option, and it may help you manage your pain and regain your normal mobility.
you have chronic pain, working with a physical therapist can help your pain go
away, and your therapist can give you strategies to keep the pain away. So,
what does physical therapy for chronic pain look and feel like, and what can
you expect from PT for chronic pain?
What Is Chronic Pain?
The simple definition of chronic pain is pain that has been
present for greater than 12 weeks.
However, it can be more complex than that, and the best way to understand chronic pain is to learn about its cousin: acute pain. Acute pain is pain that comes on suddenly and lasts for a few weeks. Typically, acute pain is caused by some traumatic event that injures your body’s tissues.
If you smash your thumb with a hammer, for instance, this causes
acute pain. The pain is sudden and severe, and you can easily discern the cause
of it. Your thumb becomes red, swollen, and painful. Over the course of a few
weeks, however, the pain goes away as your thumb heals.
Now imagine that you smash your thumb with a hammer again. Your
thumb becomes red, swollen, and painful. This time imagine your thumb pain
continues long after the signs of injury have gone away. The tissues are
clearly healed, but your thumb still hurts. When you try to move your hand, the
pain increases. This is chronic pain.
Chronic pain can be confusing, and it can prevent you from
moving normally and concentrating on your daily activities. Plus, dealing with
chronic pain can leave you and your doctor perplexed.
Often, pain occurs when there is little or no tissue damage. Why
is the pain lasting long after the tissues are healed? Why are medicines not effective
in treating your pain? Is there something really wrong? These questions may be
difficult to answer and finding the best treatment for your chronic pain may be
There are many different treatments available for chronic pain.
Finding the best one for you can take a little trial and error.
Physical therapy (PT)
Medication (oral or injected)
Supplements and natural remedies
Cognitive behavioral therapy (CBT)
There are likely more items to add to this list, and you may
find one remedy helpful while another may not be effective for your pain at
all. Physical therapy may be an option to treat your chronic pain and working
with a physical therapist has been shown to help chronic pain sufferers improve
their function while decreasing or eliminating their pain.
What to Expect
When attending physical therapy for chronic pain, your first
session will be an initial evaluation. During this session, you will meet your
physical therapist and discuss your condition.
Your therapist should ask questions about your pain and how it
behaves. Is your pain present constantly or intermittently, and how does it
affect your life? What makes it better or worse? Your physical therapist should
also ask about any previous treatments you have received and the effect those
treatments have had.
He/she might do a review of your overall medical history and
will perform various tests and measures to get a sense of any impairments that
may be contributing to your pain, including:
Range of motion
Some of these tests may increase your pain, while others may
cause your pain to decrease. Be sure to communicate with your physical therapist
how you are feeling and how sensations are changing during your evaluation.
Once your PT evaluation is complete, your physical therapist should work with you to develop realistic and attainable goals for therapy. Goals may include pain relief, extended range of motion, increased strength and improved functional mobility. Your goals should be personal and should give you a road map to follow during your rehabilitation program. Finally, your treatment can begin.
When you attend physical therapy for chronic pain, you may
experience various treatments that may be used to decrease pain, improve your
mobility, and help you fully function. Common treatments used by physical therapists
for chronic pain patients include:
Exercise: Exercise should be your main PT tool in the treatment of
chronic pain because it can help your body improve strength and mobility. Think
of exercise as a feedback loop. Your brain moves your body, so exercise is
output coming from your brain. When you can move with little or no pain, you
are reinforcing to your brain that the movement is not going to hurt. This
positive feedback allows you to move more with less pain. So while you are
getting stronger and improving mobility, you are also training your sensitive
nervous system to trust that the movement is safe.
Ultrasound is a deep heating modality that you may encounter while in PT. It is
applied to your skin and as your body’s tissues are heated, it is thought that
this improves circulation and blood flow. It is important to note that
ultrasound has not been proven to be an effective treatment for chronic pain.
Still, you may encounter this treatment during your PT sessions.
Electrical Stimulation: Transcutaneous electrical nerve stimulation (TENS) is a
therapeutic modality that uses electricity to decrease pain signals coming from
your body to your brain.
Some physical therapists employ massage
techniques to decrease pain by improving muscular blood flow and relieving
Needling: Dry needling is a
newer treatment employed by some physical therapists to decrease painful muscle
knots and trigger
points. This treatment involves using
small needles (such as acupuncture needles) to pierce muscle tissue and knots,
relieving the pain in these spots.
or Ice: Modalities like heat
and ice are often used by PTs to help decrease pain and inflammation. These
treatments have not been proven to be effective with patients dealing with
chronic pain, but they are often used as adjunct treatments during your PT
Neuroscience Education (PNE):
New research indicates that teaching patients about their pain and why it is
happening can have a positive effect on their rehab. Your physical therapist
may spend time teaching you about why you have pain, how your pain might
behave, and things you can do to take control of your pain.
Each of these treatments is designed to achieve a specific goal.
It is important that you discuss with your physical therapist the intent of the
treatment, so you know what to expect.
Finding What Works
Some Treatments Not Proven Effective
Some PT treatments for chronic pain are based on theoretical
models and have not been proven to be effective for pain. Does this mean that
they will not be effective for you? No. It simply means that in studies of
large groups of people with similar characteristics, some treatments have not
been proven to work. Understanding the research can help you make informed
decisions about your care.
Some treatments that may not be as effective for chronic pain
include ultrasound, TENS, or heat and ice.
A meta-analysis (study examining conclusions of many different studies)
concluded that ultrasound was not effective for chronic low back pain (LBP)
when compared to exercise alone or a placebo (fake treatment). The authors
concluded: “No high-quality evidence was found to support the use of
ultrasound for improving pain or quality of life in patients with non‐specific
chronic LBP.” Another meta-analysis of the use of massage for chronic pain
concluded that patients may report a 20 to 80 percent reduction in pain after a
massage, but that these reductions are temporary. Massage, however, may help
improve the mobility of tissues and feelings of well-being. Dry needling
studies show similar results, and both heat and ice are shown to give slight
short-term relief of pain.
Treatments Proven to Be Effective
Exercise has been proven to be effective for chronic pain. Pain
neuroscience education (PNE) or learning about pain and how it affects your
body, has also been shown to offer long-term benefits with pain reduction and
Research published in the Archives of Physical Medicine
and Rehabilitation showed that a graded walking program can have a
positive effect on patients with chronic pain. However, one important caveat of
the study was that adherence to an exercise and a walking program can be
difficult. Still, finding ways to maintain walking and exercising is important.
(Your PT can help with this.)
In addition, neuroscience pain expert Adriaan Louw has found
that learning about pain through pain neuroscience education (PNE) can improve
symptoms, mobility, and feelings of psychological well-being in people with
Overall, passive treatments like heat, ice, or massage may feel
good. However, if you want to take control of your pain, more active treatments
like exercise and learning about your pain are recommended.
The most important thing to remember is that your pain is
personal. Your physical therapist can work with you to find specific things
that can help you move better and feel better.
If you have chronic pain, you may find that it is difficult to
function well. Managing your pain can be challenging, as there are many
different options for you, all with varying degrees of effectiveness. Physical
therapy, with a focus on exercise and pain neuroscience education, can be an
effective way to decrease your pain and improve your mobility.
Knee pain can be
caused by disease or injury. Among American adults, approximately 25% have
experienced knee pain affecting the function of the knee. The prevalence of
knee pain has increased over the past 20 years, with osteoarthritis being the
most common cause in individuals over the age of 50. Knee pain that is caused
by injury is most often associated with knee cartilage tears. Knee injuries can
occur as the result of a direct blow or sudden movement that strains the knee
beyond its normal range of movement. Knee pain can cause difficulty performing
activities such as walking, rising from a chair, climbing stairs, or playing
sports. Physical therapists are specially trained to help diagnose and treat
knee pain, and help individuals return to their normal activities without pain
What is Knee Pain?
The knee joint is a
hinge joint that connects the tibia (shin bone), and the femur (thigh bone) at
the patella (kneecap). There are 4 main ligaments that support the knee joint.
They are the anterior cruciate ligament (ACL); posterior cruciate ligament (PCL);
medial collateral ligament (MCL); and lateral collateral ligament (LCL). There
are also 2 rings of cartilage that act as shock absorbers in the knee, called
the medial and lateral meniscus.
The most common cause
of knee pain is osteoarthritis, a condition that occurs when the cartilage that
protects the inside surfaces of the tibia and femur bones called articular
cartilage gradually wears away, resulting in pain and swelling in the knee.
How Does it Feel?
Knee pain can occur
suddenly for no apparent reason or develop slowly, as the result of repetitive
trauma. Knee pain occurs in different parts of the knee, depending on what
structures in the knee are involved. Below is a general breakdown of the areas
in which knee pain may occur and the structures of the knee that may be
Anterior knee pain, also referred to as patellofemoral pain, is pain around the kneecap (patella) in front of the knee, caused when the kneecap shifts out of position. This condition commonly affects younger females and may be due to overuse injury. Pain often occurs when performing activities like squats or stair-climbing.
Lateral knee pain is pain that occurs on the outside of the knee. It is a type of overuse injury that commonly occurs in runners when the tendon called the iliotibial band (ITB) becomes irritated. Pain is often felt when performing activities such as climbing stairs, or when walking or running.
Medial knee pain is pain that occurs along the inside of the knee when the MCL or the medial meniscus become irritated due to direct injury or overuse. Pain is felt when squatting, walking up or down an incline, or going downstairs.
Pain caused by a ligament tear may result from a direct blow to the knee, or when twisting or pivoting the knee while the foot is planted on the ground. Immediate pain and swelling usually occur, and the knee may feel unstable—like it will “give out”—when an individual attempt to put weight on the involved leg.
Pain caused by osteoarthritis may occur anywhere in the knee where cartilage has broken down. This type of knee pain may begin as mild and progressively worsen. It can become increasingly difficult to walk long distances, fully bend and straighten the knee, climb stairs, or squat to sit in a chair. The knee also may swell intermittently with increased activity.
How Is It
therapist will make a diagnosis based on your symptoms, medical history, and a
thorough examination. Your physician may order an X-ray and magnetic resonance
imaging (MRI) to complete the diagnosis.
therapist will perform an evaluation that will start with discussing your
medical history and your symptoms. Your therapist will ask questions to
determine where your pain is located, if you sustained any trauma or injury to
the knee, and what functional daily activities are painful or difficult for you
to perform. Your physical therapist will perform tests to find out if you have:
Limited range of motion in the knee.
Pain in the knee with certain movements.
Weakness in the muscles around your hip, knee, or ankle.
Limited flexibility in your hip, knee, or ankle.
Difficulty performing activities, such as rising from a chair or climbing stairs.
Problems with your balance or coordination.
Difficulty controlling the knee during certain activities.
Difficulty performing specific sports activities (for athletes).
How Can a Physical
Based on the findings
of your evaluation, your physical therapist will develop a customized
rehabilitation program to ensure a safe return to your desired activities. Some
general treatment techniques may include:
Pain management. Your physical therapist may provide treatments using different “modalities” such as ice, heat, ultrasound, or electrical stimulation to help decrease pain and swelling.
Manual therapy. Your therapist will apply manual (hands-on) therapy to gently guide movement of the knee area to restore joint and tissue mobility.
Therapeutic exercises. Your physical therapist will prescribe specific strengthening, flexibility, and endurance exercises to address your specific needs and goals.
Functional exercises. You will learn individualized exercises designed to help you return to your home, work, and sport activities. These also may include balance and coordination exercises.
Self-care instruction. Your physical therapist will teach you ways to manage your pain at home and design a safe and effective home-exercise program based on your specific condition, which you can continue long after your formal physical therapy sessions have ended. You also will learn how to avoid placing unnecessary forces on the knee during your daily activities for years to come.
How Can a Physical
Therapist Help Before & After Surgery?
therapist, in consultation with your surgeon, will be able to tell you how much
activity you can do depending on the type of knee surgery (such as total knee replacement) you undergo. Your
therapist and surgeon also might have you participate in physical therapy prior
to surgery to increase your strength and motion. This can sometimes help with
recovery after surgery.
your physical therapist will design a personalized rehabilitation program for
you and help you gain the strength, movement, and endurance you need to return
to performing the daily activities you did before.
Can this Injury or
Condition be Prevented?
To help reduce knee
pain, it is important to maintain a healthy lifestyle, perform regular safe
exercise, get adequate rest, and eat healthy foods. Weight management is
important for maintaining healthy knee function, as increased body weight puts
extra pressure on all the joints, including the knees. Ideally, individuals of
all ages should regularly perform some form of flexibility, strength, and
It also is important
for athletes to perform appropriate warm-up exercises and stretches on a daily
basis and before beginning physical activity.
CAUTION: If any
exercise or activity provokes knee pain, seek professional help before the symptoms
What Kind of
Physical Therapist Do I Need?
therapists are prepared through education and experience to treat knee pain.
However, you may want to consider:
A physical therapist who is experienced in treating people with knee pain. Some physical therapists have a practice with an orthopedic and sports medicine focus.
A physical therapist who is a board-certified clinical specialist or who completed a residency or fellowship in orthopedic, manual, or sports physical therapy. This therapist has advanced knowledge, experience, and skills that may apply to your condition.
General tips when
you’re looking for a physical therapist (or any other health care provider):
Get recommendations from family and friends or from other health care providers.
When you contact a physical therapy clinic for an appointment, ask about the physical therapists’ experience in helping people who have underlying knee pain.
During your first visit with the physical therapist, be prepared to describe your symptoms in as much detail as possible, and say what makes your symptoms worse.
Your car needs regular maintenance, so you
probably have a mechanic. Your eyes and teeth are important, so you see your
optometrist and dentist regularly. You get an annual physical from your family
physician. You might even be getting ready to see your accountant to get your
yearly income tax done. What about your physical therapist? Do you and your
family have one? If not, you should. Your body is a lot like your car. It’s got
multiple systems, all of which are complex, and all of which have to be working
well for it to function. Physical therapists are experts in maintaining,
diagnosing, and treating the movement system. Like the braking or ignition
system in a car, most people only think of the movement system when it’s not
working the way it should.
DON’T NEGLECT YOUR MOVEMENT SYSTEM
Similar to the systems in your car, problems
with your movement system are much easier to deal with if they’re caught and
treated early. This prevents small issues from becoming larger ones. For
example, if you have a little bit of weakness, and balance that’s not quite up
to par, improving those early could prevent a sprained ankle, or a fall and a
An annual movement screen from your physical therapist can find small issues
that you may not have noticed with your strength, balance, flexibility, or
coordination. Many of these minor issues can be fixed with a few exercises at
home, or with just a few visits.
WHAT TO EXPECT
A screen of your movement system is quick and easy. Your annual visit may include: ● A history of your injuries, as well as a health history ● Assessment of your strength, balance, flexibility, etc. ● A review of your movement goals (do you want to run a marathon? Get on and off the floor easily playing with your grand kids?) ● A review and update of your exercise program
At any given time, about 25% of people in the United States report having low back pain within the past 3 months. In most cases, low back pain is mild and disappears on its own. For some people, back pain can return or hang on, leading to a decrease in quality of life, or even to disability. If your low back pain is accompanied by the following symptoms, you should visit your local emergency department immediately: • Loss of bowel or bladder control • Numbness in the groin or inner thigh
There are 3 different types of low back pain: • Acute – pain lasting less than 3 months • Recurrent – acute symptoms come back • Chronic – pain lasting longer than 3 months.
ARSO therapists can teach you how to use the following strategies to prevent back pain: • Use good body positioning at work, home, or during leisure activities. • Keep the load close to your body during lifting. • Ask for help before lifting heavy objects. • Maintain a regular physical fitness regimen—staying active can help to prevent injuries.
Not all low back pain is the same, so your physical therapist will design an individualized treatment plan for your specific back problem. Treatments may include: • Manual therapy • Specific strengthening and flexibility exercises • Education • Training for proper lifting, bending, and sitting; for doing chores both at work and in the home; and for proper sleeping positions • Assistance in creating a safe and effective physical activity program • Use of ice or heat treatments or electrical stimulation to help relieve pain
