Frozen shoulder – who can help

Monday, July 13th, 2009

Frozen shoulder – what’s that all about?

We’ve seen a few of these lately at C1 Chiropractic Health Centre and we’ve come to see that a whole lot of madness is spouted on about them. Most irritatingly the term is wildly misused and so any painful shoulder with any loss of movement is labelled as a ‘frozen shoulder’. So, let’s start by calling it what it really is: adhesive capsulitis.

What is adhesive capsulitis?
‘Frozen shoulder’ is nearly a slang term – not as bad lumbago but getting close, and refers to loss of arm movement in the shoulder joint with inflammation of the connective tissue of the joint capsule surrounding the shoulder joint. These connective tissues protect the joint, they stabilize the joint and they control a large part of the range of motion of the joint. In an adhesive capsulitis they become inflamed, thickened, shortened and eventually bind together, hence the medical term – adhesive capsulitis which sort of says what it is on the tin.
It affects about two percent of the general adult population. It is most likely to occur in people between the ages of 40 and 60. At present I don’t think that there is any data to suggest that any gender, occupation, or arm domination is more predominant in those who suffer from it. However, diabetic individuals do have an increased risk of developing frozen shoulder. The key point here is the missing bit – the why does it occur and I think this is the strange and interesting part of the problem. We (and I don’t just mean us at the clinic) have no real idea what causes it.

What does it feel like?
Adhesive capsulitis often starts after some minor trauma, dislocation, prolonged immobilisation, heart attack (myocardial infarction) or neck problems (cervical radiculitis). It kicks off with a progressive limitation of shoulder motion which may or may not be painful. However, if you try to push the limited range of motion boundary you will feel pain. This stage is sometimes called the ‘freezing’ stage. The condition then progresses until all movement is reduced, or to the ‘frozen’ stage. Surprisingly, at this point it is common to have no pain. However, this all reversed during the recovery phase and it gets painful again but this will abate when movement is finally restored. This recovery period varies depending on how long the problem has been there and the severity of it.

What can we do to help?
Chiropractic is an effective treatment option for frozen shoulder because it focuses, not on the symptoms, but on the root of the problem. I have yet to meet a patient with AC who has not got some significant neck problems and this may well signpost the way to the elusive underlying cause. However, the most crucial way that chiropractic helps frozen shoulder is in prevention
If it has started then early diagnosis is vital because the condition can be reversed. AC needs more than just chiropractic and we use a mix of chiropractic and sports injury therapy at the clinic and this treatment is very effective.
One thing that seems to work really well with AC patients is having them lie on their back with bad arm in external rotation holding a weight with a hot pack on the shoulder for about 15 minutes. They all seem to get the range of motion back faster with this added to the treatment plan.

What treatment is there for frozen shoulder?

Monday, July 13th, 2009

The great problem with adhesive capsulitis (a.k.a. frozen shoulder) is that there is no standard agreed treatment for it. Now the reason for this, I suspect, is because there is no really good understanding of cause – signs and symptoms yes, but cause, no. Therefore addressing the underlying problem becomes a real issue: if there is no understood cause to tackle then curing it is always going to be difficult. So loads of stuff is written about treating the symptoms – which itself has value and several approaches have been advocated (have a look on the internet and see how many options are open to you). However, there have only been a few good research studies on AC and they only looked at a few of the options available. (And here’s a thought, a lack of fully rounded research into complementary care is explainable as it would be hard to gather enough cases to conduct a study. This is unfortunate but reasonable, especially taking into consideration how ‘conservative’ many of these procedures are. Cutting your shoulder ligaments apart or sticking some serious drugs into your joints similarly suffers from a paucity of research which is a little strange considering how un-conservative the treatments are – how did they get away with that one I wonder).

When assessing the claims of some available treatments remember that the condition will fully recover on its own even without any treatment whatsoever. So, bearing this in mind, surely the aim of treatment is either to relieve pain while nature gets on with resolving the underlying problem or to speed up the recovery process and both if at all possible. So then choose a therapy which:
1. Reduces pain.
2. Accelerates healing
3. Causes no further damage

So what do we choose?

Painkillers – well, yes they clearly have there place but let’s call them what they really are Painmaskers as ‘killers’ is a marketing deceit designed to give us the impression that the pain has gone (and therefore you are mended) when actually the structures are just as damaged and likely to get worse as you abuse them thinking you are fine.

Injections – have a place but here’s a bit I found on the web:
“Repeated cortisone injections are not healthy for tissues. Small amounts of cortisone in the body are probably reasonable, but repeated injections can cause damage to tissues over time. Sometimes this is of little concern. For example, if a patient has severe knee arthritis, and a cortisone injection every 6 months helps significantly, then the number of injections probably does not matter too much. On the other hand, if a patient has shoulder tendonitis, but an otherwise healthy shoulder, the number of injections should probably be limited to prevent further damage to these tendons.” Did you notice the word damage to tissues – what! How on earth can that be anything but wrong – it’s like saying collateral damage is good. Madness. Try anything before going here as I suspect you are going to need those damaged structures to work in the future.

Massage therapy – done well is certainly the first step. We at C1 Chiropractic Health Centre advocate this alongside some chiropractic manipulation of the neck (C5 dermatome stuff).

Acupuncture – I think so but I’ll let others comment on this.

Surgery – Please don’t be tempted to rush into a surgical treatment option until you have really, really, really explored all the other treatment choices.

Can chiropractic help with chronic low-back pain

Monday, July 13th, 2009

“Chronic low-back pain – The single most expensive cause of pain and disability in working age adults”
The Spine Journal (2008) 8 (1):1-278

In the Journal of the North American Spine Society there is a comprehensive review of ‘Chronic Low-back Pain’ and evidence for and against the numerous methods of managing patients with this condition.

Currently there are several influential clinical guidelines about this sort of stuff such as the Ontario Workers’ Safety and Insurance Board of Canada’s guidelines and in Europe, the European Back Pain Guidelines which are all available online. In the UK the British Medical Research Council sponsored the BEAM Trial which has shown “convincingly that both manipulation alone and manipulation followed by exercise provide cost-effective additions to best care (for low-back pain patients) in general practice”

However this review is different with each form of management being tackled by another health care expert, so the review of manipulation under anaesthesia is done by chiropractors. The editors are critical of what they call a supermarket response to low-back care where patients are offered a range of untested treatments (with over 200 different forms of care available in the USA) and even those with the most evidence, such as chiropractic still have questions that must be asked. Every year there appear to be more treatments available with strong and commercial advocates but with generally limited scientific evidence.

This does present a problem because the gold standard would be high-quality randomized controlled trails (RCT) but the cost of conducting these is, as the report states, “beyond the realm of possibility”. So, we are left using evidence-informed care rather than evidence-based care. Though there are more randomized controlled trails examining chiropractic care than any other chronic low-back intervention.

The best available evidence today is not materially different from the recommendations in the Practice Guidelines on Acute Low-Back Pain in Adults published in the US by the Agency for Health Care Policy and Research (AHCPR) in 1994. The reviews support the findings of this work and add that “a reasonable approach to CLBP would include education strategies, exercise, simple analgesics, a brief course of manual therapy in the form of spinal manipulation, mobilization or massage, and possibly acupuncture”. And, tellingly, that these treatments should be preferred to more complex or invasive approaches.

These reviews are available, free, on www.science-direct.com/science/journal/15299430 and click on Vol.8 Issue 1.

The one covering chiropractic is really useful. It has a history of chiropractic, a description of the examination and treatments in practice today and is seen as being an excellent authority for all concerning chiropractic especially referring medical doctors. A couple of telling lines:

“Spinal manipulative therapy (SMT) or spinal mobilization is superior to usual medical care for patient improvement”

“For pain reduction “SMT with strengthening exercises is similar to prescription NSAIDs with exercise in both the short-term and long-term”

High-dose SMT is superior to low-dose SMT “for pain reduction in the short term”

And from the 9 trials where there were patients with chronic and acute low-back pain the evidence was good that:

SMT is superior to usual medical care alone

SMT/MOB is superior to physical therapy and to home exercise in the long-term

Now this is a change from the old approach where it was recognised that chiropractic was effective in treating acute low-back pain as this now demonstrates that chiropractic is effective in treating chronic as well as acute low-back pain.

One of the key advantages of SMT over drug and surgery lies in respect to harm. The review noted that the only likely side effects of SMT are minor, temporary and typically do not interfere with activities of daily living – a major advantage over spinal surgery I’d argue.

Cervicogenic headache – what is it and can chiropractic help?

Monday, July 13th, 2009

Arguably, everyone has had a headache at one time or another and at this moment in time more than 10% of the UK’s population is currently suffering from a headache of one form or another and this is why headaches are the main reason for seeking advice from your GP.

There are several different types of headache. Over 90% of these types of headache are known as primary headaches which have no underlying medical condition. These include all tension-type migraines, cluster and cervicogenic headaches.

What is a cervicogenic headache?

Cervicogenic headaches are headaches where the pain originates in the neck and upper shoulders and are neatly clinically defined as “pain that is present in the head, but which originates in the cervical spine”.

However, cervicogenic headaches, like other types of headaches are different for different people and, depending on who you are, some are more severe and some are less severe, some are present in the head and others have pain behind the eyes.

The ‘classic presentation’ of a cervicogenic headache is where pain starts in the occipital region (the base of your skull at the back) and in the cervical spine and then progressively spreads upwards into the head.

Commonly, with cervicogenic headaches, there will be muscular trigger points in these suboccipital muscles of the neck and in the shoulder muscles. These trigger points can also send shooting pain to the head when they are physically manipulated and will be very, very tender.

Helpfully, there are two key symptoms that are generally exclusive to cervicogenic headaches. Firstly, the headache can be made worse or actually initiated by head or neck movement or passive neck positioning, especially when extended towards the side that is prone to pain and secondly, there is marked tenderness in the suboccipital region.

Who is likely to get them?

In our experience nearly all patients with cervicogenic headaches have abnormal neck posture (this is nearly exclusively Anterior Head Carriage) or have restricted range of neck motion.

And they are caused by?

We see these on a daily basis and in our experience at C1 Chiropractic Health Centre is that these headaches are a by-product of trauma (such as whiplash), neck injury, intervertebral disc disease, progressive joint arthritis, chronic tension or muscle trauma due to poor prolonged posture or severe stress with this last one being the most commonly encountered headache in our clinic.

How’s it treated?

Unlike many common forms of headaches, such as migraine, and cluster headaches, they often do not respond well to over the counter medications such as analgesics or common pain medications such as Panadol. Although the cervicogenic headache sufferer will note some relief from the symptoms of pain experienced when taking a pain relieving medication, once the preparation has worn off, the symptoms, and pain will return. In order to gain relief treating the symptoms simply isn’t enough and a more holistic approach must be taken for long-term pain reduction.

One of the most effective ways of relieving cervicogenic pain is with Chiropractic treatment using Chiropractic Manipulative Therapy (CMT). We manipulate the bones in the neck area that have moved out of alignment to reduce inflammation and irritation and so reduce pain.

A major spine care review was published in 2008. The authoritative report by the Bone and Joint Decade 2000 – 2010 Task Force on Neck Pain and its Associated Disorders which built on the impressive report produced Quebec Task Force on Whiplash. This report follows seven years of literature review and original research from more than 50 researchers and the editor of the Spine journal described it as a “milestone” report.

It covers all aspects of neck pain, including headaches, arm-pain and other neck generated symptoms. Tellingly, it states that neck pain is a “multi-factorial and episodic or recurring problem” and adds that because patients have many differing personal factors underlying their problems best management requires informing and educating patients on their options and respecting their preferences.

It then goes on to add that most patients have grade 1 or 2 neck pain (so low grade and therefore ‘primary headaches’) and that treatments, with similar evidence of safety and effectiveness, are education, exercise, mobilization, manipulation, acupuncture, analgesics, massage and low-level laser therapy. But treatments NOT supported by the evidence are surgery, collars, ultrasound, electrical muscle stimulation, TENS, most injection therapies including corticosteriod injections for the cervical joints.

According to recent studies published in the Journal of Manipulative, And Physiological Therapeutics, the results indicated that spinal manipulation had a significant positive effect in cases of cervicogenic headache. In this study, 53 participants who were sufferers of cervicogenic headaches were studied closely. Half of the subjects were given chiropractic manipulation as treatment, while the other half of the subjects received deep friction, and low laser massage. The study lasted over the course of a three-week period. While the two groups of sufferers did notice improvement with the care given to them, the group that were involved in the soft tissue treatments noted only a significant decrease in the hours per day that they were experiencing headache. The manipulation group showed improvement in all three of the measurement criterion being studied. Those who received chiropractic treatment in the study noticed a 36% decrease in their pain medication usage; their headache hours were decreased by 69% and their headache intensity had also decreased by 36%. At the 12 week point, one month after the trial ended, there was “a clinically important and statistically significant” advantage in pain reduction for the patients receiving chiropractic manipulation. The patients receiving 8 treatments had a 9.4 advantage in pain reduction. Those receiving 16 visits had a 17.2 pain reduction advantage. However, the difference was not statistically significant because of the small trial.

Haas w Peterson et al. (2007) Dose-response of spinal manipulation for cervicogenic headache: short –term outcomes from a randomised trail, Abstract in Proceedings of the WFC’s 9th Biennial Congress, 161-162

If your head hurts on a regular basis, and you suffer from headaches continually, especially if the pain seems to radiate from your spine or upper shoulder area, this may be a sign of cervicogenic headache. This is especially true is you have suffered trauma to your spine or neck such as whiplash or injury. And you should see your Chiropractor, get it diagnosed and sorted and stop complaining.

Core stability – what exercises should I do and what should I avoid

Monday, July 13th, 2009

Core stability

A vast amount of rubbish is spouted about core stability by those poorly trained and frankly pretty dim blokes you meet in gyms. The terms ‘core function’, ‘core strength’, and ‘core stability’ have become chants with no real understanding of what the terms mean – ask one of them to explain the difference between stability and strength and then which of the two is more important and see what a panic this creates. However, you will, every now and then, meet one of them who has a profound understanding of these concepts and, if this is the case, ‘bind them to you with hoops of steel’.

The guru on all of this is Prof Stuart McGill, whose lectures and books we have devoured, and I would argue that he is the leading researcher in the world on low back stability. He talks about the following:

The Unstable Spine
To explain how injuries occur to the low-back from such apparently easy tasks as bending over to pick a pencil up off the floor he uses the concept of the unstable spine. It is worth having in your mind the idea that bending over puts a fairly high load through your low-back; think of it as similar to lifting a plank up by the thin end. His spectacular and spectacularly painful research shows that these daily tasks can cause your spine to ‘buckle’ if the spine isn’t working well or is unstable. This buckling can lead to tissue irritation and injury. What causes this to happen is a momentary dip in neural activation of some of the deep intervetebral muscles, leading to a slight rotation in one of the spinal segments. His solution to this is to train the deep muscles to “stiffen the spine against buckling” and improve its stability.

The Stable Spine
The vertebral bodies have to be able to move and they are brilliantly made to rotate in the sagital, frontal and horizontal plane, as well move along the three axes of these planes. Of course all joints have an inherent ‘joint stiffness’ because of the bony architecture, passive joint capsules and surrounding ligaments. Additionally, the muscles are able to control stability of these joints by coordinated muscle coactiviation. So, for us the task of creating a stable spine is testing but the pattern is there and we are rarely working with nothing. The goal is to deliver ‘sufficient stability’ which directly relates to optimal stability and mobility with no compromise to the spine. This can be done with exercises that provide coactivation of the deep intrinsic spinal muscles and abdominal wall (transverse abdominis) muscles.

The Main Lumbar Spine Stabilizers
Prof McGill used deep intramuscular electrodes (told you it was painful – but he did do it on himself) to identify the functional roles of the significant spinal stabilizer muscles. He also produced some mathematical models of spinal muscular activity and some amazing computer models to find the key muscles. He suggests that the important intrinsic muscles of the spine include the multifidus, quadradus lumborum, longissimus, iliocostalis and the transverse abdominins. Some gym staff surprises there – no rectus abdominis there so the six-pack may only be for decoration.

The Low Back Training Program
From McGill’s research on low-back stability, the data suggest that the healthiest training for the spinal flexors involves muscular endurance not strength training. He adds that “the safest and mechanically most justifiable approach to enhancing lumbar stability through exercise entails a philosophical approach consistent with endurance, not strength; that ensures a neutral spine posture when under load (or more specifically avoids end range positions) and that encourages abdominal muscle co-contraction and bracing in a functional way.” Bracing can be understood as if the muscles are guy ropes for tent poles as it is a neurophysiological phenomenon involving co-contraction of the abdominal wall and deep intrinsic muscles of the spine in an effort to better stabilize the low back.

Flexion-Extension “Cat-Camel” Warm-up
He recommends beginning with about six flexion-extension cycles of the “cat-camel” exercise. But he adds that these are done as a mobility exercise to reduce any present stresses on the spine, not as a stretch. These are shown really well on:

http://www.ccohs.ca/oshanswers/psychosocial/backexercises.html

(and you can see the Prof’s fingerprints all over this one.)

Quadratus Lumborum Training
For quadratus lumborum training he recommends the horizontal isometric side bridge (stick that in Google images and you’ll see what we mean) which can be done from a knee supporting position on the floor or a more testing version which utilizes a feet supported version. Another advanced version that involves the maximal involvement of the quadratus lumborum and obliques, with co-contraction of the critical spine muscles and transverse abdominis, is the rolling side bridge.

Rectus Abdominis, Obliques, and Transverse Abdominis Training
Prof McGill states that there is no single abdominal exercise that effectively challenges all of the abdominal musculature. He recommends several versions of crunches for the rectus abdominis and obliques. Pleasingly, he suggests avoiding sit-ups (with bent or straight legs) due to the high psoas muscles activation and the compressive loads this causes in the low-back. Similarly, leg raises also cause a great deal of psoas muscles activation and lumbar spine compression.

Back Extensor Training
Front lying (prone) upper torso (or leg) lifts off the floor may not be wise for people with low-back pain as these may place to much load on the spine. In this exercise the lumbar spine pays a very high compression penalty to a hyperextended spine (approximately 4000 to 6000 N) which transfers load to the facet joints and crushes the interspinous ligament. This exercise is certainly contraindicated for anyone at risk of low-back injury or re-injury due to the high spine loads and the extended posture. In my opinion it should not be prescribed at all.

The alternative exercise Prof McGill recommends is the “Bird-Dog” exercise or sometimes in the UK ‘supermen’. This exercise adequately engages the longissimus, iliocostalis, and mutifidus muscles of the spine, with much less stress to the spinal segments. Again a great site for a few pictures is: http://www.ccohs.ca/oshanswers/psychosocial/backexercises.html
