With ninety percent of the driving forces coming from the upper body, it is little surprise that swimmer’s shoulder is a common condition in swimming. The shoulder is a complex joint, and as swimming placed it under load, an appreciation of its function and limitations can help keep the body injury free. This is especially true for those who swim very regularly or have poor stroke technique, as they are most at risk.
Shoulder mobility as a strength and a weakness
Compared to other joints in the body, the shoulders and hips have an unparalleled range of motion. This is due both of them having ball and socket joints capable of a 360 degree conical movement. However, stability for each of these joints differs. The hip joint fits snugly like a ball in a glove, as the rounded head of the thigh bone, fits into the deep, cup shaped socket of the pelvis. Unlike the hip, the shoulder has a small flat socket about half the size of the ball, along with several other bones, plus a collection of muscles and tendons that support this wide range of motion. Although one of the largest and most complex joints in the body, its unique structure is also a weakness, as the shoulder accounts for up to 20% of all athletic injuries and is the most commonly dislocated joint in the body.
This balance between shoulder mobility and stability is put to the test during sports that require overhead motion. Racket sports such as tennis, or throwing sports like volleyball require two or three patterns of overhead movement. Swimming however, requires multiple overhead movement patterns and a steady conical 360 degree motion of the humerus, the bone of the upper arm. This bone fits into a socket of the scapula, more commonly known as the shoulder blade, which has a cuff of cartilage called the labrum. This ring of rubbery tissue helps keep the ball like head of the humerus in place.
As the humerus fits loosely into the shoulder joint compared to the hip, a collection of muscles and tendons known as the rotator cuff, provide support for raising and rotating the arm. To further aid fluid motion there is a small sac of fluid called a bursa that protects and cushions the rotator cuff tendons. It lies between the rotator cuff and the roof of the shoulder blade, which has two bony projections, the coracoid process and the acromion, which is above the bursa and attaches to the clavicle. Otherwise known as the collar bone, the clavicle, makes up one of three bones of the shoulder, the other two being the previously mentioned humerus and scapula. These three bones are connected to the shoulder by four joints, one being the ball and socket joint of the humerus and scapula, one for where the scapula meets the ribs at the back, and two for the clavicle which joins the scapula at one end and the chest bone at the other.
All of these structures have the potential to be injured, and as such swimmer’s shoulder can derive from a variety of sources. An appreciation of the forces at work upon the body during swimming, can provide a greater understanding of the root cause of swimmer’s shoulder.
The sources of swimmer’s shoulder
Good swimming technique requires a greater range of motion and flexibility of the shoulder compared to other sports and plays a major role in the upper body’s ability to provide locomotion. This placing of the shoulder under load, is further increased since swimming is performed in a fluid medium. As opposed to air, water creates greater resistance and forces upon the structures of the shoulder.
In one study, two thirds of the elite swimmers reported shoulder pain. In some cases swimmer’s shoulder can involve irritation to the tendons of the rotator cuff muscles, but it can also be due a range of painful shoulder overuse injuries such as impingement. This is where the shoulder blade’s bony point that joins with the collar bone, rubs on the rotor cuff and bursa. This can then lead to inflammation of the bursa, known as bursitis, or tendonitis.
The four tendons that make up the rotator cuff and one of the bicep tendons are most commonly affected by tendonitis, once again as a result of wear. Like with any other joint in the body, the ligaments, tendons, and muscles around the shoulder can tear or become loose. This can lead to instability in the shoulder and the chance of greater injury, such as a tear to the the ring of cartilage that holds the humerus in place, or dislocation. Also these areas can be affected by chronic conditions such as osteoarthritis.
The repeated overhead motion of the arm in swimming and pressures placed upon the shoulder joints in water, mean that immediate care of a newly acquired injury and preventative measures are essential. Seeking physiotherapy treatment can identify the exact area of injury, alleviate pain and then planning can be put into place to regain stability, strength and flexibility. For example a gym program with some simple strength and flexibility exercises can be easily prescribed. Through future self management of the swimmer’s shoulder condition there lies the opportunity to proactively train the body so as to minimise the risk of injury.
Managing shoulder health
First of all as with any inflammation injury, the PRICE principle should be applied to the shoulder. This is achieved by protecting the injured area, resting the shoulder, applying ice for 15-20 minutes every two to three hours, compression with a bandage and elevation of the arm above the level of the heart.
Once the area has recovered due to rest or treatment by a physiotherapist, and a strengthening plan has been devised for the injured area and surrounding structures, then it is time to venture back into the water. At this point advice from your physiotherapist, doctor should be taken and the help of a qualified swimming professional or experienced swimmer could ease the transition back to the pool.
After all investigating and understanding proper swimming stroke technique, could prevent a relapse of injury and aid in the rehabilitation of an recovered shoulder. It is also important to know the limits that a recovering shoulder can take, being sure to train conservatively so as to avoid tired muscles. This is also true for those who are injury free, as training at a limit within the body’s fitness level will maintain stability of the shoulder and aid correct function.
Prevention through correct technique
Swimmer’s shoulder can develop with all styles of swimming, with freestyle, backstroke and butterfly seen to be the most responsible for injury, as the arms circle overhead. Although the most gentle looking, breast stroke still places pressure on other parts of the body, and like the other styles, requires good technique to avoid injury. So an option could be to vary the types of swim stroke performed, as this can provide rest and recovery to muscles, joints and tendons that would otherwise be overworked. Refining the technique and building the strength of each swimming stroke style can also avoid other swimming conditions that effect the knees, neck and lower back.
In general terms there are four areas of swimming technique that can aid protection against shoulder injury. As with land based activities, good posture is essential, so keeping the shoulders back and the chest forward will help. Next is developing symmetrical body rotation, that is encouraged by a balanced left and right breathing pattern. This allows for better support to the rotator cuff and generates more power by engaging the muscles of the back and core.
Regarding the best practice for stroke technique, hand placement as the arm enters the water and the shape of the arm when pulling through the water, are also essential in injury avoidance. It is best to have a flat hand as it enters the water at the start of a stroke. This is fingertips first, rather than thumb whereby the arm is rotated outwards. Lastly as the hand then catches the water and pulls through, the elbow should be high so that the water is pushed back, rather than down when the elbow is dropped or the arm is very straight.
Are our devices giving us neck pain?
There are millions of people right now looking down at their smartphone or tablet. Do you ever stop to think about what this might be doing to your neck and upper back?
At Saanich Physiotherapy and Sports Clinic, we are seeing a huge increase in the amount of neck, upper back, shoulder and arm pain which is all related to posture when using devices. From texting on the smartphone to watching TV on the tablet in bed, we are all guilty in some way. And sadly, we are seeing more and more children coming in with these issues too.
Consider how much your head actually weighs. On average, it weighs 4.5-5kg. When sitting or standing upright, this weight is supported by the lower neck vertebrae, intervertebral discs, muscles and ligaments. When you then lean your head forward when looking at your smartphone, the relative weight of your head on your neck muscles can increase up to 27kg! Just by looking down at your phone, you can increase the force on your lower neck by 5 times!
When maintaining this position for a period of time, the muscles will fatigue and stop working, meaning that the force of your head is now being held up by small ligaments, the neck joints and the discs in the neck. It is no wonder people are having more and more neck pain.
The term “Text Neck” is becoming more commonly accepted as a diagnosis for neck pain caused by prolonged use of smartphones and tablets. If left untreated, this massive increase in force in the lower neck and lead to headaches, increased arching of the spine, general pain and tightness and arm pain from irritating nerves in the neck. It can also cause weakening of the muscles in the neck which can lead to ongoing pain, stiffness, headaches or arm pain in the future.
With the increase in children having smartphones and even the use of tablets in school, there are becoming more and more postural issues arising which is definitely a concern for ongoing and long term neck and upper back problems later in life.
Text Neck can be treated. Your Physiotherapist may use joint mobilizations, soft tissue massage, taping or even dry needling to help restore normal movement within the joints and muscles.
However, it is imperative that you strengthen the muscles in the neck and upper back to prevent long term issues. Your Physiotherapist will tailor a program for you to complete at home or might even recommend core conditioning or yoga classes for a supervised strengthening program.
If you, your children or another family member or friend are guilty of using their smartphone or tablet too much and are noticing pain or discomfort in their neck, upper back or arm make sure you book an assessment with your Physiotherapist sooner rather than later!

A Physiotherapist’s Guide to Osteoarthritis
“Arthritis” is a term used to describe inflammation of the joints. Osteoarthritis (OA) is the most common form of arthritis and usually is caused by the deterioration of a joint. Typically, the weight-bearing joints are affected, with the knee and the hip being the most common.
An estimated 27 million Americans have some form of OA. According to the Centers for Disease Control and Prevention, 1 in 2 people in the United States may develop knee OA by age 85, and 1 in 4 may develop hip OA in their lifetime. Until age 50, men and women are equally affected by OA; after age 50, women are affected more than men. Over their lifetimes, 21% of overweight and 31% of obese adults are diagnosed with arthritis.
OA affects daily activity and is the most common cause of disability in the US adult population. Although OA does not always require surgery, such as a joint replacement, it has been estimated that the use of total joint replacement in the United States will increase 174% for hips and 673% for knees by 2030.
Physical therapists can help patients understand OA and its complications, and provide treatments to lessen pain and improve movement. Additionally, physical therapists can provide information about healthy lifestyle choices and obesity education. This is important because some research shows that weight loss can reduce the chance of getting OA. One study showed that an 11-pound weight loss reduced the risk of OA in women.
What is Osteoarthritis?
Your bones are connected at joints such as the hip and knee. A rubbery substance called cartilage coats the bones at these joints and helps reduce friction when you move. A protective oily substance called synovial fluid is also contained within the joint, helping to ease movement. When these protective coverings break down, the bones begin to rub together during movement. This can cause pain, and the process itself can lead to more damage in the remaining cartilage and the bones themselves.
The cause of OA is unknown. Current research points to aging as the main cause. Factors that may increase your risk for OA include:
•Age. Growing older increases your risk for developing OA because of the amount of time you’ve used your joints.
•Genetics. Research indicates that some people’s bodies have difficulty forming cartilage. Individuals can pass this problem on to their children.
•Past Injury. Individuals with prior injury to a specific joint, especially a weight-bearing joint (such as the hip or knee), are at increased risk for developing OA.
•Occupation. Jobs that require repetitive squatting, bending, and twisting are risk factors for OA. People who perform jobs that require prolonged kneeling (miners, flooring specialists) are at high risk for developing OA.
•Sports. Athletes who repeatedly use a specific joint in extreme ways (pitchers, football linemen, ballet dancers) may increase their risk for developing OA later in life.
•Obesity. Being overweight causes increased stress to the weight-bearing joints (such as knees), increasing the risk for development of OA.
How Does it Feel?
Typically, OA causes pain and stiffness in the joint. Common symptoms include:
•Stiffness in the joint, especially in the morning, which eases in less than 30 minutes
•Stiffness in the joint after sitting or lying down for long periods
•Pain during activity that is relieved by rest
•Cracking, creaking, crunching, or other types of joint noise
•Pain when you press on the joint
•Increased bone growth around the joint that you may be able to feel
Caution: Swelling and warmth around the joint is not usually seen with OA and may indicate a different condition or signs of an inflammation. Please consult with your doctor if you have swelling, redness, and warmth in the joint.
How Is It Diagnosed?
Osteoarthritis is typically diagnosed by your doctor using an x-ray, but there are signs that may lead your physical therapist to suspect you have OA. Joint stiffness, difficulty moving, joint creaking or cracking, and pain that is relieved with rest are typical symptoms.
How Can a Physical Therapist Help?
Your physical therapist can effectively treat OA. Depending on how severe the OA is, physical therapy may help you avoid surgery. Although the symptoms and progression of OA are different for each person, starting an individualized exercise program and addressing risk factors can help relieve your symptoms and slow the condition’s advance. Here are a few ways your physical therapist can help:
•Your therapist will do a thorough examination to determine your symptoms and what activities are difficult for you. He or she will design an exercise program to address those activities and improve your movement.
•Your therapist may use manual (hands-on) therapy to improve movement of the affected joint.
•Your physical therapist may offer suggestions for adjusting your work area to lessen the strain on your joints.
•Your physical therapist can teach you an aerobic exercise program to improve your movement and overall health, and offer instructions for continuing the program at home.
•If you are overweight, your physical therapist can teach you an exercise program for safe weight loss, and recommend simple lifestyle changes that will help keep the weight off.
In cases of severe OA that are not helped by physical therapy alone, surgery, such as a knee or hip replacement, may be necessary. Your physical therapist will refer you to an orthopedic surgeon to discuss the possibility of surgery.
Can this Injury or Condition be Prevented?
The best way to prevent or slow the onset of OA is to choose a healthy lifestyle, avoid obesity, and participate in regular exercise.
