The Role of Physical Therapy
Physical therapy with a trained professional may be useful if pain has not improved after 3 – 4 weeks. It is important for any person who has chronic low back pain to have an exercise program. Professionals who understand the limitations and special needs of back pain, and can address individual health conditions, should guide this program. One study indicated that patients who planned their own exercise program did worse than those in physical therapy or doctor-directed programs.
Physical therapy typically includes the following:
Education and training the patient in correct movement.
Exercises to help the patient keep the spine in neutral positions during all daily activities.
Incorrect movements or long-term high-impact exercise is often a cause of back pain in the first place. People vulnerable to back pain should avoid activities that put undue stress on the lower back or require sudden twisting movements, such as football, golf, ballet, and weight lifting.
Exercises performed after a simple diskectomy do not seem to provide much added benefit over time.
Specific and regular exercise under the guidance of a trained professional is important for reducing pain and improving function, although patients often find it difficult to maintain therapy.
Exercise and Acute or Subacute Back Pain
Exercise does not help acute back pain. In fact, overexertion may cause further harm. Beginning after 4 – 8 weeks of pain, however, a rehabilitation program may benefit the patient.
An incremental aerobic exercise program (such as walking, stationary biking, and swimming) may begin within 2 weeks of symptoms. Jogging is usually not recommended, at least not until the pain is gone and muscles are stronger.
Patients should avoid exercises that put the lower back under pressure until the back muscles are well toned. Such exercises include leg lifts done in a facedown position, straight leg sit-ups, and leg curls using exercise equipment.
In all cases, patients should never force themselves to exercise if, by doing so, the pain increases.
Exercise and Chronic Back Pain
Exercise plays a very beneficial role in chronic back pain. Repetition is the key to increasing flexibility, building endurance, and strengthening the specific muscles needed to support and neutralize the spine. Exercise should be considered as part of a broader program to return to normal home, work, and social activities. In this way, the positive benefits of exercise not only affect strength and flexibility but also alter and improve patients’ attitudes toward their disability and pain. Exercise may also be effective when combined with a psychological and motivational program, such as cognitive-behavioral therapy.
There are different types of back pain exercises. Stretching exercises work best for reducing pain, while strengthening exercises are best for improving function.
Exercises for back pain include:
Low Impact Aerobic Exercises. Low-impact aerobic exercises, such as swimming, bicycling, and walking can strengthen muscles in the abdomen and back without over-straining the back. Programs that use strengthening exercises while swimming may be a particularly beneficial approach for many patients with back pain. Medical research has shown that pregnant women who engaged in a water gymnastics program have less back pain and are able to continue working longer.
Spine Stabilization and Strength Training. Exercises called lumbar extension strength training are proving to be effective. Generally, these exercises attempt to strengthen the abdomen, improve lower back mobility, strength, and endurance, and enhance flexibility in the hip, the hamstring muscles, and the tendons at the back of the thigh.
Yoga, Tai Chi, Chi Kung. Practices originating in Asia that combine low-impact physical movements and meditation may be very helpful. They are designed to achieve a physical and mental balance and can be very helpful in preventing recurrences of low back pain.
Flexibility Exercises. Flexibility exercises may help reduce pain. A stretching program may work best when combined with strengthening exercises.
Specific Exercises for Low Back Strength
Perform the following exercises at least three times a week:
Partial Sit-ups. Partial sit-ups or crunches strengthen the abdominal muscles.
Keep the knees bent and the lower back flat on the floor while raising the shoulders up 3 – 6 inches.
Exhale on the way up, and inhale on the way down.
Perform this exercise slowly 8 – 10 times with the arms across the chest.
Pelvic Tilt. The pelvic tilt alleviates tight or fatigued lower back muscles.
Lie on the back with the knees bent and feet flat on the floor.
Tighten the buttocks and abdomen so that they tip up slightly.
Press the lower back to the floor, hold for one second, and then relax.
Be sure to breathe evenly.
Over time increase this exercise until it is held for 5 seconds. Then, extend the legs a little more so that the feet are further away from the body and try it again.
Stretching Lower-Back Muscles. The following are three exercises for stretching the lower back:
Lie on the back with knees bent and legs together. Keeping arms at the sides, slowly roll the knees over to one side until totally relaxed. Hold this position for about 20 seconds (while breathing evenly) and then repeat on the other side.
Lying on the back, hold one knee and pull it gently toward the chest. Hold for 20 seconds. Repeat with the other knee.
While supported on hands and knees, lift and straighten right hand and left leg at the same time. Hold for 3 seconds while tightening the abdominal muscles. The back should be straight. Alternate with the other arm and leg and repeat on each side 8 – 20 times.
Note: No one with low back pain should perform exercises that require bending over right after getting up in the morning. At that time, the disks are more fluid-filled and more vulnerable to pressure from this movement.
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.
Some common spinal injuries and conditions we treat:
Acute lower back (lumbar) pain due to spinal disc and/or facet joint injuries
Chronic low back (lumbar) pain
Sciatica – referred pain and symptoms into the lower limb
Pelvic dysfunction syndromes . Often diagnosed in patients who feel ‘out’.
Childbirth related instability and acute pain syndromes of the lower back and pelvis.
Spondylolisthesis (forward slip of one vertebrae on the vertebrae directly below it)
Spondylosis (disc space narrowing combined with degenerative changes in the facet joints common with age)
Acute neck pain due to facet joint and/or spinal disc injury
Chronic neck pain
Brachialgia-referred pain and symptoms into the arm, ‘pinched nerve’ pain and/or pins and needles/numbness (known as paraesthesia)
Mid-back (thoracic) and rib (costovertebral joint) pain (which, in some cases, refer pain around the chest wall)
Acute/chronic (myofascial) trigger point conditions. (These are tender and hypersensitive coin sized zones within the muscle tissue that can cause local pain and tightness and can also refer to distant sites.)
Muscle and joint stiffness
Causes of Spinal Pain
Acute and chronic spinal pain is experienced due to the stimulation, via mechanical or chemical irritation, of small nerve endings, nerve root or spinal cord sheaths, nerve cords, complex pain mechanisms in the central nervous system or a combination of the above.
Acute Spinal Pain
This can involve findings of bulging disc, disc protrusion or disc prolapse/rupture. Disc problems are very common in the lower back (lumbar spine). They are often associated with episodes of bending, bend with twist or prolonged sitting /driving which distorts the rim of the disc causing acute pain. In addition it can produce pressure on the spinal nerves in the lower back which produce symptoms known as sciatica. This is felt as pain, pins and needles sensation, numbness and/or weakness in the leg(s). In the neck (cervical spine), disc injuries can cause debilitating pain into the neck and commonly severe pain into the arm called brachialgia due to compression of the spinal nerves in the neck. This is commonly referred to as ‘pinched nerve’.
These joints are small joints which flank the disc on either side and behind the spinal discs. They are like a finger joint in their structure and when injured swell and inflame and cause acute pain and restriction of movement. They can be sprained in an injury or activities involving twisting, arching and reaching upward movements. In the neck they can become overstrained by an awkward night’s sleep leading to a condition known as ‘Acute Wry Neck’. They can cause local pain and also refer pain to neighbouring and even distant sites.
The joints of the pelvis can suffer acute injuries through high force trauma such as motor vehicle/bicycle accidents, contact sports, slips and falls on to the ground/floor, landing from a height, or when the female pelvis is vulnerable before and after childbirth. Injury and acute instability syndromes can occur which involve the sacroiliac and pubic joints. Lumbo-pelvic dysfunction conditions are common in the sporting population. Muscle imbalance, asymmetrical posture and structural alignment, as well as poor activation and stabilising strength (core control) can create syndromes such as chronic back pain, Osteitis Pubis (OP), recurrent hamstring strains, and contribute to a range of soft tissue injuries/conditions in the lower body.
This refers to the soft tissue layer involving the muscles, tendons and fascial tissues. This can be injured acutely and cause local pain at the site of injury but can also be responsible for ache and pain at distant sites. Myofascial pain is often associated with damage to deeper joint structures, namely disc and facet joints as either a primary (injured tissue) and/or secondary (protective spasm) component of the acute injury.
Our spinal columns are made of twenty four vertebrae stacked one above another on the pelvis. 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 at 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. In the upper neck and thoracic areas we tend to have more facet joint strains and in the lower cervical spine and lumbar spine areas, disc injuries are more frequent. This is because our upper spine joints allow us to turn our heads to see, hear and smell, so they need mobility but do not support much weight. Our lumbar spine bears around half our body weight and as we move and sit, there are huge, sustained, compressive loads on our discs.
CAUSES OF BACK PAIN
Disc injuries are the most common cause of low back pain and can range in severity from a mild intermittent ache, to a severe pain where people cannot move. Disc injuries occur mainly during sudden loading such as when lifting, or during repetitive or prolonged bending forces such as when slouching, rowing, hockey and while cycling. They are often aggravated by coughing and running. A flexed posture during slouching, bending or lifting is a frequent cause of disc damage because of the huge leverage and compression forces caused by gravity pulling down on the mass of the upper body.
It is important to understand that damage from small disc injuries is cumulative if discs are damaged at a faster rate than they can heal and the damage will eventually increase until it becomes painful. Pain sensing nerves are only on the outside of the disc, so by the time there is even small pain of disc origin, the disc is already significantly damaged internally where there are no nerve endings to feel pain with.
There may be a previous history of pain coming and going as the damaged area has become inflamed, perhaps was rested or treated, settled for a while but as the underlying problem was not fixed, the pain has flared up repeatedly since. This type of disc injury responds very well to Physiotherapy treatment.
A marked disc injury causes the outer disc to bulge, stretching the outer disc nerves. In a more serious injury, the central disc gel known as the nucleus, can break through the outer disc and is known as a disc bulge, prolapse or extrusion.
Spinal muscles are often blamed as the cause of spinal pain but this is rarely the cause of the pain. Muscle pain may develop as the muscles contract to prevent further damage as they protect the primary underlying painful structures. This muscle pain is secondary to the underlying pathology and when the muscles are massaged, given acupuncture etc, there is temporary relief but the pain will often come back, as the muscles resume their protective bracing. Treatment must improve the structure and function in the tissues which the muscles are trying to protect. The most common sources of primary pain are the discs, facet joints and their ligaments.
There are four facet joints at the back of each vertebra, two attaching to the vertebra above and two attaching to the vertebra below. A facet joint strain is much like an ankle sprain and the joints can be strained by excessive stretching or compressive forces. The joint ligaments, joint lining and even the joint surfaces can be damaged and will then produce pain.
Facet joint sprains can occur during excessive bending but typically occur with backward, lifting or twisting movements. Trauma such as during a car accident or during repetitive or prolonged forces such as when slouching or bowling at cricket.
There are many other sources of back pain including arthritis, crush fractures and various disease processes. Your Physiotherapist will examine your back and advise you should further investigation be necessary.
SYMPTOMS OF BACK PAIN
Symptoms of structural back pain are always affected by movement. This is important to understand. Symptoms, usually pain but perhaps tingling and pins and needles, are often intense and may be sudden in onset but also may be mild and of gradual onset. There are other conditions which can produce back pain such as abdominal problems, ovarian cysts and intestinal issues. If you have symptoms in these areas which are not affected by movement, you must consult with your doctor. If you have chest, jaw or upper limb pain which is unaffected by movement, you must attend your doctor or hospital immediately.
Facet joints, discs, muscles and other structures are affected by our positions and movements. More minor problems produce central low back pain. With more damage, the pain may spread to both sides and with nerve irritation, the pain may spread down into the thigh or leg. As a general rule, disc pain is worse with bending, lifting and slouching and facet joint strains are worse twisting and bending backward or sideways. A severe disc problem is often worse with coughing or sneezing and on waking in the morning.
DIAGNOSIS OF BACK PAIN
Diagnosis of back injuries is complex and requires a full understanding of the onset 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 known as co-existing pathologies and each of these are treated as they are identified. Where the Physiotherapist requires further information or the management may require injections or surgery, the appropriate x-rays, scans and a referral will be arranged.
UPPER BACK AND LOWER BACK PAIN RELIEF
Eighty percent of adults will experience severe spinal pain at some time in their life. Much of this pain is called non-specific low back pain and is treated with generic non-specific treatment. This type of treatment often fails to provide lasting relief. However, Musculoskeletal Physiotherapists have developed specific diagnostic skills and specific treatment techniques, targeted to specific structures. We identify the structure and cause of the pain producing damage and develop specific advice and strategies to prevent further damage and promote healing.
Specific techniques are chosen to correct the structural and mechanical problems. Among many choices, treatment may include joint mobilisation, stretching, ice, strengthening and education. As normal tissue structure and function returns, there is a reduction in the inflammation and the pain will subside.
When normal movement has been achieved, the inflammation has settled and the structures have healed, your new strategies will reduce the possibility of the problem recurring. We use this specific approach to reduce or stop chronic pain.
While we have the choice to manipulate, adjust or click joints, patients with ongoing pain will seldom benefit from repeating these techniques. This is because our tissues are elastic and the benefit of the quick stretch of manipulation is lost, as the elastic tissues tighten and shorten again. Adjustments of this type have little long term benefit and often lead to an unhealthy dependence on the provider. Your Physiotherapist will choose a safer and more appropriate treatment for you.
PROGNOSIS OF BACK PAIN
Physiotherapy for back pain can provide outstanding results but it is a process, not magic. The damage which produces pain in a back takes time to develop and also time to repair and heal. You will understand there are often several interacting factors to deal with and patient compliance is necessary.
