So we all know that feeling that we get after exercise – we feel generally happier, less stressed, less anxious and also sleep better. Exercise produces a rush of happy hormones we also know as endorphins. So what are these endorphins and why do they make us feel happy?
Endorphins are chemicals that are produced in our brains in response to stress or pain. Running, doing a hard workout, playing a sport or any exercise at all that increases our bodies stress response has the ability to make our brains release endorphins. The endorphins have the ability to travel through our neural networks as a neurotransmitter. One thing we do know about endorphins is that they make us feel really good. So how does this work then?
A part of the brain called the hypothalamus sends a signal to increase endorphin uptake through our bodies neural network when we subject ourselves to certain activities like exercise, sex, eat certain foods or experience pain. The endorphins then attach themselves to specific receptor sites within our neural network – these are called opioid receptors. These special receptors have the ability to block out pain signals and also to increase that euphoric happy feeling we get after we exercise. It is the same receptors that are locked onto when we take pain relief in the form of opiates.
Once we achieve a positive result in something we do, either though through exercise or simple activities like sticking to a plan you’ve made, your brain will also release another happy hormone called dopamine. Dopamine is responsible for us feeling addicted to pleasure seeking behaviors. By setting regular and achievable exercise goals that you reach it is highly possible to make exercise the trigger for your brain to release dopamine.
Serotonin is another one of our brains happy hormones that act as a natural anti-depressant. When we exercise serotonin levels in our brain increase and so does your level of happiness.
I know all these terms may seem confusing but there is another very important happy hormone called oxytocin. Oxytocin is released when we feel loved, cared for and connected to others. Your brain will also release oxytocin when you are kind to others.
So no matter how hard it may seem to get yourself moving on some days, putting one foot in front of the other and pushing yourself to move and exercise is not only good for your muscles and joints but also stimulates your brain. You’ll produce your very own happy hormones, reduces your stress levels and have you wanting to repeat it all over again next time. Give your fellow team mates, friends and family an encouraging kind words regularly as well- it will not only help them feel happy but will increase your happiness as well.
“Tension headaches” are often talked about and we see a lot of patients with these headaches. In our diagnosis of these conditions, about eighty five percent of all headaches arise from the neck, or cervical spine, which refers pain into the head through the nerves which go to both areas. Neck problems cause head pain because some of the nerves which come from the spinal cord have branches which go to the upper neck joints and other branches which spread over the back of the head, with still others going to the front of the head. When one area is sore the brain interprets the pain as coming from all the areas the nerve branches go to.
CAUSES OF TENSION HEADACHES
Patients who have “Tension Headaches” or “stress headaches’’, are often very busy and have work related problems, a tough boss, urgent deadlines, problems with managing work flow and they often have trouble sleeping because of work problems and their worries. This causes the patient to be mentally and emotionally stressed and their relationships at work and with their families suffer.
They develop a headache which they cannot shake and they feel helpless, tired, tense, anxious and in pain. We have seen many cases where the headaches have continued for weeks and frequently kept recurring, sometimes over many years.
It is important to understand that a Tension Headache is due to “physical tension” in the tissues, often from a poor working position and the damage it has caused, not the other mental “tensions” listed above. Once full neck movement has been restored with treatment, the tissues have healed and the postural strains have been removed, patients often cope better with the other aspects of their lives. This is where Physiotherapy can help by breaking the vicious “Physical Tension” cycle. It is better to think of these as “structural headaches”.
Our neck is made of seven vertebrae stacked one above another. They support the head and they are joined together at the front by discs and at the back by facet joints. When we bend forward, the vertebra above tilts and slides forward, compressing the disc and stretching the facet joints which join the back of the vertebrae. When we bend backward, the disc compression is reduced at the front and the facet joints are compressed at the back. The junction of the first vertebra and the head does not have a disc and the joints there are particularly susceptible to leaning forward which causes the weight of the head to strain the joints, ligaments and muscles as gravity causes a shearing force as the head slides downward.
The neck muscles are often blamed as the cause of pain but this is rarely the whole story. Muscle pain often develops as the muscles contract to prevent further damage, as they protect the primary underlying structures. This pain is secondary to the underlying pathology and when the muscles are massaged, given acupuncture, etc, there is temporary relief but the pain will always comes back as the muscles resume their protective bracing. The most common sources of primary pain are the facet joints and their ligaments in the upper neck and the discs in the lower levels of the neck.
A facet joint strain is much like an ankle sprain, strained by excessive stretching or compressive forces. The joint ligaments, joint lining and even the joint surfaces can be damaged.
In the upper neck, facet joint strains typically occur during excessive bending or twisting movements and may follow trauma such as a car accident causing whiplash but generally, Tension Headaches occur with prolonged forces such as slouching, keying and reading.
There is often a previous history of pain coming and going as the damaged area became inflamed, was treated and settled for a while but as the underlying problem still remained, the pain flared up repeatedly every time it was strained. This type of injury, although often chronic, responds very well to specific Physiotherapy treatment.
There are many other sources of headaches and neck pain including arthritis, crush fractures and various disease processes. Your Physiotherapist will advise you should a more serious condition be suspected.
SYMPTOMS OF TENSION HEADACHES
Symptoms of “Tension Headaches” arising in the neck, are always affected by movement of the head and neck. This is important to understand. Symptoms are sometimes severe and may be sudden in onset but also may be mild and of gradual onset. There are other serious conditions which can produce headaches. If you have severe headache symptoms which are not affected by movement and a recent history of fever or nausea, you must consult a doctor urgently.
Facet joints, discs, muscles and other structures are affected by our neck positions and movements and when damaged, will respond very well to Physiotherapy treatment.
DIAGNOSIS OF TENSION HEADACHES
“Tension Headaches” often appear complex and require a full understanding of the history and a comprehensive physical examination. It is important for your Physiotherapist to establish a specific and accurate diagnosis to direct the choice of treatment. In some cases, the pain may arise from several tissues and these coexisting pathologies are treated individually as each is identified. Where the Physiotherapist requires further information or management may require injections or surgery, the appropriate x-rays, scans and a referral will be arranged.
TENSION HEADACHE RELIEF
Some of these cases will temporarily respond to a general non-specific treatment such as bed rest, ice and anti-inflammatories, however Musculoskeletal Physiotherapists have developed diagnostic skills and treatment techniques, targeted to stopping “Tension Headaches”. We will identify the reasons for the development of the pain and advise strategies to promote healing and to prevent further damage.
Specific techniques are chosen to correct the structural and mechanical problems. Among many choices, treatment may include joint mobilisation, stretching, ice, strengthening and education.
When normal function has been achieved, the inflammation and pain has settled and the structures have healed, using your new strategies will reduce the possibility of the headaches ever recurring. We use this approach to reduce or stop chronic pain. While we have the choice to manipulate or “click” joints, those with ongoing pain will seldom benefit from repeated “adjustment”. This is because our tissues are elastic and the benefit of the quick stretch of manipulation is lost as the tissues tighten up again. Potentially dangerous “adjustments” of this type have little long term benefit and can lead to an unhealthy dependence on the provider. Your Physiotherapist will choose a safe and appropriate treatment for you.
PROGNOSIS OF TENSION HEADACHES
Physiotherapy for “Tension Headaches” can provide outstanding results but it is a process, not magic. The damage which produces “Tension Headaches” takes time to develop and time to repair and heal. You will understand there are often several interacting factors to deal with and your compliance is necessary.
Lateral epicondylalgia or tennis elbow is the most common cause of musculoskeletal
pain located near the elbow. It is commonly known as tennis elbow as it can be a significant problem amongst tennis players. However, you do not need to play tennis to have experienced this injury. It is reported that approximately 40% of people will experience this type of pain at some point in their life and it usually presents in males or females aged between 35 and 54. Lateral epicondylalgia is an injury to the forearm muscles that act to extend the wrist and fingers. The point of injury occurs at the site where the muscle attaches to the bone near the elbow.
What causes tennis elbow?
Lateral epicondylalgia is usually caused by an overload of the forearm extensor muscles where the load is more than what normal muscle tissue can handle. Associated neck or shoulder pain may also contribute to the presentation. Common causes or activities can include:
Poor technique during sports or other activities i.e. racquet sports
Manual workers with jobs involving repetitive gripping and hand tasks
Office workers with jobs involving repetitive use of the keyboard and mouse
Symptoms of lateral epicondylalgia include tenderness over the side of the elbow and pain with activities involving gripping or wrist extension. There may also be areas of tightness through the forearms and pain when the involved muscles are stretched. Your physiotherapist will be able to diagnose this condition based on physical examination and gathering a complete history of your injury. Your physiotherapist may also send you for medical imaging scans to assist in ruling out other causes of elbow pain including muscle tears, ligament injury and elbow instability or pain that is originating from the neck.
The goals of treatment are to reduce pain, promote healing and decrease the amount of stress applied to the elbow. Also, to restore full strength and movement of the elbow and wrist. Early treatment may include:
Rest from aggravating activities
Exercise programs involving gradual strengthening and stretching
Massage and other soft tissue techniques
Taping to reduce load on the muscle and tendon
Acupuncture or dry needling
Once pain levels have decreased, physiotherapy will involve prescription of more difficult or specific strengthening exercises and correction of any predisposing biomechanical or technique problems. These are essential to prevent future aggravation and shorten recovery time.
Braces are available which are designed to assist in alleviating pain by reducing the amount of stress on the tendon. However, not all people will benefit from using a brace. Your physiotherapist will be able to guide you through all stages of rehabilitation.
At first it was just a niggle in your knee when you climbed stairs or were squatting. Then the pain and stiffness became more than a niggle and you began to feel it when walking, sitting and resting.
You may be hearing popping or cracking sounds in your knee, and notice that your knee “gives out” every now and again.
The knee is an amazing but complicated joint and knee pain is one of the most common reasons that people visit a physiotherapist.
Pain behind the kneecap is commonly called runner’s knee because it is often seen in athletes and people with an active lifestyle, although it can also be seen in everyone from the young adolescents during growth spurts to elderly people.
The medical term is patellofemoral pain syndrome. It is pain behind the kneecap where your patella (kneecap) slides along the groove in your femur (thighbone) beneath.
Pain and stiffness occurs when the kneecap does not slide smoothly and misaligns causing it to rub against your femur. Repeated mis-tracking causes pain, stiffness, and ultimately can cause damage to your kneecap joint surface.
Knee pain is most commonly noticed during activities that involve knee bending, jarring or weight bearing.
People most at risk are those whose sport or activity includes running, jumping or the need to land in a squatting position. Sports most commonly associated with knee pain include running, netball, volleyball, basketball, tennis, skiing and cycling. Many tradies such as tilers and carpet layers also have problems.
Causes of Runner’s Knee
Overuse – increased activity or increased duration and intensity of the activity
Changes in footwear or playing surfaces
Tight outer thigh muscles and weaker inner thigh muscles causing the kneecap to be pulled to one side
A twisting injury
Flat feet and lack of arch support
Weak hip control muscles
First aid for Runner’s Knee
Generally, knee pain is gradual onset, which means it gradually increases in severity over time.
As with most injuries, the best initial first aid is rest, ice packs (15 minutes at a time every 2-3 hours), and taking anti-inflammatory painkillers such as ibuprofen.
You do not need a referral from a doctor to see a physiotherapist. If the pain is moderate, then you can seek treatment with your Physiotherapist immediately.
Physiotherapy is a proven treatment for runner’s knee. Your physiotherapist may initially tape or strap your kneecap to help pull it back into alignment and reduce pain.
Massage and joint mobilisation techniques are also commonly used to reduce swelling and restore movement.
You will be prescribed exercises to stretch and strengthen muscles that may be contributing to the problem. These exercises will change as you heal and will gradually increase in intensity to match your recovery.
If you wish to continue exercising to maintain your fitness during your treatment, then explore swimming, deep-water running and low-impact gym equipment such as elliptical trainers.
Depending on your knee pain cause, you may also be advised to explore arch supports, orthotics or different footwear. You may also require postural or technique correction in your chosen sport to stop problems from recurring, as well as a strength and conditioning plan to get you back to full competitive fitness.
In our experience, over 90% of runner’s knee physiotherapy clients will be pain free within six weeks of starting treatment. However, for severely damaged joints or arthritic joints, surgery may be required.
Things to Remember
Runner’s knee or patellofemoral pain syndrome is a common cause of knee pain.
It is a gradual onset injury and is most commonly noticed during activities that involve knee bending, jarring or weight bearing.
Physiotherapy is a proven method to speed healing, and prevent recurrence of knee pain.
Future management may also involve assessment of your gait and posture during exercise, and prescription of arch support or custom made orthotics.
