Patient: "What's wrong with me? Do I need a scan? Am I normal?" Physio: "What is normal?"

-

I often find my patients asking me this question before I have even assessed them:

“Do you think that I should get a scan?”

My typical response is "no or certainly not yet."

They say "but won’t it show exactly what is wrong with me?”

The problem is that the scan will show all the issues that you have, but what is relevant or just incidental?

You see what is normal?

Patients presume that we are all perfect with no abnormalities so a scan will show the single abnormality causing our pain. This simple isn't true.

Here are some great examples of this point:


In the knee, Cyteval (2008) actually found meniscal (cartilage) tears on MRI scans in 1 in 3 middle aged and elderly people and these individuals had no symptoms or pain at all and would consider themselves normal. A similar finding was also found by Beattie et al (2005), they found that 60% of pain free 20-68 year olds showed abnormalities in at least three of the four regions of the knee.

In the shoulder, Connor et al (2003) performed MRI scans on the shoulders of elite athletes that perform overhead throwing as part of their sport.  Now bear in mind that these athletes were fully fit with no pain or symptoms and it was found that 40% of them had rotator cuff tears on the MRI’s!
In the general public it was found that 13% of asymptomatic (no symptoms) people aged 50 to 59 had rotator cuff tears on ultrasound scans. They found tears in 20% of people aged 60 to 69 and 51% in the over 80’s age group (Tempelhof et al 1999).
Sher et al (1995) found similar results with 50% of asymptomatic patients over 60 having Rotator cuff tears on imaging.

In the hips it was found that 54% of pain free hockey players had labral tears in their hips on MRI scans and 70% were found to have an abnormal pelvis (AOSSM 2010).

In the neck it was found that there is a lack of association between cervical spine curvature & neck pain (Grob et al 2007) and in the lower back Boden et al (1990) found the following:
Asymptomatic 60 year olds had abnormal findings on 57% of MRI's. 36% of which were herniated discs & 21% was spinal stenosis. They even found in the younger age groups that degeneration or bulging of a disc was found in at least 1 lumbar level in 35% of 30-39 year olds.

Not only can people with no pain have structural damage that is irrelevant but the people in pain aren't getting their pain from actual damage. You see pain is not always a sign of damage or harm, which is shown by this piece of evidence:

The brain is where pain is felt, it is not simply a signal that is received simplistically from the problem area, it has to be interpreted and processed by the brain. This means that the brain can actually regulate the pain that is felt, regardless of the severity of structural injuries or damage. In some people the central nervous system is in a more active and excited state when it comes to pain. It is these people that will likely feel more pain with activity, even though the activity is actually harmless and causing them no damage (Wand et al 2011).

So overall it is pretty clear that if you have pain, a scan will find lots of things that are wrong with you but it won’t tell you which of these ‘things’ is the cause of your symptoms and it certainly won’t get rid of your problem. Plus just because you are in pain doesn't always mean that you are causing damage or harm to yourself. In these cases people need to change the way they think about the relationship of pain and injury. The aim is to get back to some normal function and activity without the fear of causing more harm or damage. So my advice is to not worry or fixate on a structural abnormality, as this in itself will make you worse. Naturally you will overprotect yourself and this could be detrimental and make you feel worse. As a physio I would always want to do my own assessment first before I would consider a scan and even then you need to take the result with a pinch of salt!

    Very good writing sir.If you don't mind your great writing is spoiling for the background color.It is definitely true that Scan scanning is helping us to find out lots of thing that are happening with us but it never tell the cause of the symptoms.Great writing and keep it up.physiotherapist in Ryde

Patella Tendinopathy

-
Image
I hear different terminology used all the time, so what is tendinitis, tendinosis or tendinopathy? Tendinopathy: This is a broad term encompassing painful conditions occurring in and around tendons, which includes tendinitis and tendinosis. Tendinitis: This basically means inflammation of a tendon. Tendinosis:  This means degeneration of tendon (Meaning cumulative damage). So what does this mean to me? For a long time tendinitis was the term used and it was considered that injured tendons were simply inflamed. Then the thinking shifted to the thought that there was little or no inflammation present in these conditions (Andres & Murrell 2008). However as is with research, the thinking is changing again: There may be an inflammatory response associated with chronic tendinopathy, even though recent opinions had decided it to be non-inflammatory (Rees 2013). So both types can occur! This is important as the way that you treat each one has to...

Cubital Tunnel Syndrome

Heard of Cubital Tunnel Syndrome? Probably not but you may have heard of Carpal Tunnel Syndrome. Well they are similar but Carpal Tunnel Syndrome is in the wrist and hand whereas Cubital Tunnel Syndrome is in the Elbow. What is Cubital Tunnel Syndrome? Basically it is a compression neuropathy, which means that a nerve is "trapped”. The nerve at fault in this case is the ulna nerve and where it gets “trapped” is in the cubital tunnel of the elbow: See the below picture: How common is it? It is the second most common compression neuropathy in the upper limb (Palmer & Hughes 2009). What causes it? A common cause is frequent bending of the elbow or constant repetitive pressure on the elbow itself. This then irritates the nerve and it is irritated too much then it becomes a “neuropathy”. What are the symptoms? The patient will complain of pain and numbness in the ring and little finger and weakness is common. If left untreated then this ...

Ever wondered what the click in your hip is? Firstly you need to know a little about the anatomy of the area. Bones: Ilium, Ischium, Pubis, Femur: Ilium: Acetabulum (lunate surface, margin of acetabulum) Anterior inferior iliac spine Anterior superior iliac spine Ala (wing of ilium) (gluteal surface and iliac fossa)) Iliac crest (outer lip, tuberculum, intermediate zone, inner lip) Gluteal lines (anterior, inferior and posterior) Posterior superior iliac spine Posterior inferior iliac spine Greater sciatic notch Body of Ilium Illiopubic eminence Arcuate line Auricular surface for the sacrum Iliac tuberosity Ischium: Ischial spine Lesser sciatic notch Body of Ischium Ischial tuberosity Ramus of ischium Obturator foramen Acetabulum Acetabular notch Pubis: Superior pubic ramus Pubic tubercle Obturator crest Inferior pubic ramus Acetabulum Pecten pubis (pectineal line) Symphyseal surface Obt...
