Diabetes, your feet and the podiatrist in Covid-19

Do you know your foot health risk status? Have you had your feet thoroughly examined by a podiatrist?  Experts Worldwide in their guidelines for the management of diabetes recommend an annual foot examination at the very least. This foot examination establishes the risk for complications or your Foot Health Risk Status. If you are aware of this, so many foot problems associated with Diabetes could be prevented.

These foot complications can be as simple as a painful corn or as complicated as an amputation. Of course if you have reduced sensation – peripheral neuropathy – there won’t be much pain and probably non at all.

As a podiatrist I would like to be celebrating an improvement in the foot health of South Africans, but unfortunately many people with diabetes have never seen a podiatrist, mistakenly believing that since they have no visible foot problems everything is fine.

Diabetes causes changes to the circulation and nerves to the legs and feet which often develop slowly and almost without notice.  I have heard people say that they have the less serious diabetes “the second type.” Comments like this make me realise that the Foot Health message is still not reaching our patients clearly.

Managing diabetes is a team effort and the podiatrist is a member of the team. If you neglect your feet and have no idea if they are showing the effects of diabetes, you are probably going to develop, corns, callus, blisters, ulcers and worse. Do you know the quality of your circulation? Are you sure you can feel everything with your nerves?

Why not commit to better foot health today by making an appointment with a podiatrist for a diabetic foot assessment?

High Heels in the Spotlight Again

The visual delights of high heels were the subject of a post on this website on 24 March 2008 – go back and have a look. Recently however, the “high heels issue” was the subject of a motion at the UK Trades Union Congress (TUC), in September this year.

High heels

The Society of Chiropodists and Podiatrists (SCP) tabled a motion calling on employers who promote the wearing of high heels………..to examine the hazards involved. They suggested further that employers should not be able to insist on the wearing of high heels by female workers as part of a dress code.

It received massive media coverage, even pushing  Prime Minister Gordon Brown off the the early pages of some newspapers.

The dangers of long term (even short term) wearing of high heels are of back, hip and knee pains caused by the change in natural lower limb alignment. The forces placed on the metatarsals (balls of the feet) are estimated to increase sevenfold as the heel height increases. In addition there is an increased risk of  falling or tripping.

Needless to say there was intense debate of the issue. With one newspaper calling  it ‘raucous.”

If you compare your gait (way you walk)  barefoot or in low heeled shoes, with your gait in high heels, you can easily see that in heels your knees don’t extend, the heel can’t hit the ground first followed by the rest of the foot going over it – ‘heel over toe walking’ – so the muscles act differently and the joints get stressed. High heels shorten stride and cause a jarring to the joints.

There is evidence of the use of lower heels on airplanes, when female cabin crew use lower heels for their in-flight duties when they often spend long periods on their feet.

However, when we look back at the post of 24 March 2008, we get to see that high heels are all about image! The hunter and the hunted. The allure of a long leg attached to a 9cm stilleto heel and the associated ‘rock & roll’ of the hips, arms, shoulders and anything else, is why high heels are worn by women and men will watch whilst women endure!

So until your bunions get really painful, your feet look like the front of a bricklayers trowel, the varicose veins resemble a set of train tracks, your corns are hard and yellow and your joints ache all the time due to arthritis. Ladies strut your stuff and visit your podiatrist regularly.

On the other hand, according to the SCP, this is a serious health and safety issue  in the UK, with ‘two million days lost each year to ilness resulting from lower limb disorders.’

Ultimately, it comes down to the right to choose. Or should that be Jimmy Choo’s!

Interesting cause of Heel Pain

Heel pain can be a really crippling  problem at all ages and especially for adult males. I have recently had an email from a 60 year old man complaining of heel pain. 

He described “sharp shooting pains in the left heel area. Usually when it comes under tension – even slightly, say from bending at the waist – or on impact – even the slightest.”

He went on to explain the pain as “odd, insignificant, but very sharp when it occurs.” He had only become aware of the pain in the past few days and said that the only change of habits was that he had started doing quite a lot of swimming. He didn’t indicate that he had had any injury.

My first thoughts were a series of questions:

 – “Do you have any lower back pain?

 – “How strong are your abdominal muscles?”

– “Does it come on spontaneously when sitting in the car or at the computer?”

– “Do you have any residual joint damage from sports injuries or osteo-arthritis?”

Shooting pains like this are usually associated with nerve entrapment,  pinching, or tight muscles like the hamstrings. At this age, osteoarthritis of the spine is a common cause. However, in this case, I suggested that the pain could be associated with the new range of movement since he started swimming.

Treatment for heel pain, begins with trying to find the cause, including the possible underlying cause at this age of being overweight, with a protruding belly! Not so in this case. Bearing in mind that this was an email communication and the symptoms were clearly described, I suggested the following:

• Start by gently stretching your lower back when lying on your back on the floor
• In this position, with knees bent and feet flat, roll gently side to side, all the time pressing your lower stomach into the ground
• In the same position, curl your knees up to your chest
• Another fun exercise is to kneel on all fours; extend your left arm out in front and your right leg out behind you; hold this for 10 seconds and change sides!
• A Physiotherapy consult is advisable at the same time

A few days later, the gentleman diagnosed the problem as tension-related. He actually tried a rather risky move – “I can provoke sustained pain by crouching and then arching my back to put the whole back, rear leg muscles under tension.”

 Luckily he was able to get up from this position, not call the Fire Brigade to lift him up and take him to hospital!

There is no apparent foot problem of pronation or flat feet, so it does sound like a nerve – related problem.

Then out of the blue, another man of similar age visited the practice with similar symptoms. By me moving the foot into certain positions that stretched his lower back, I was able to reproduce the burning, shooting and tingling pains he complained of.

Doing some research on heel pain reveals many causes; nerve entrapment is one of the more difficult to diagnose.

Prevent a fall-visit your podiatrist

Many older people suffer a fall with consequent injury such as a fractured  shoulder, wrist, hip, ankle or foot. In the UK there is an active falls prevention initiative, promoted by the National Health Service.  Not so in South Africa, although we are aware of the problem.

Have you ever thought how the state of your feet could contribute to a fall? Podiatrists should be  involved in preventing falls and your visit to one could help to prevent one.

Hazel Tomkins, a British podiatrist, writing in Podiatry Now has detailed how your feet can cause a fall.

So, if you want to stand on your own two feet here’s what to look out for.

Any corn, callus, ulceration, painful nail condition alters the way your foot hits the ground. This usually makes walking uncomfortable and unsteady. With age, the cushioning fatty pad on the soles  of the feet thins out – giving less protection to the bones and joints underneath.

Changes to the basic shape of the feet alters the ability to walk evenly. Often the cause of these changes is reduced muscle strength. On the other hand, any change in posture – quite common as we age – is associated with weakening of our muscles, so there is the potential for loss of balance or unsteadiness.

Watch out for changes to the length of your legs after hip or knee replacement surgery. The pain has gone but you really do need to do all the physiotherapy to restore muscle strength and balance.

At the same time there are many changes to hearing and eyesight which affect the ability to balance and see clearly what is going on around us.

If you have any nerve changes associated with diabetes (neuropathy), you are disadvantaged, because you have a reduced ability to respond to the sensory stimuli around you. On the other hand, arthritis can cause deformity as well as stiffness, making movement difficult, slower or unsteady.

Research into barefoot walking showed a 19% worse performance when barefoot compared with even a least unstable shoe. Going barefoot or stocking feet dramatically increases the falls risk.

Simple you might think, I’ll wear slippers or shoes. Well this is an area of some dispute. There is good scientific evidence that if you change to a lower or flat heel after a lifetime of wearing high heels, you have a greater risk of falling! At the same time there is research which suggests that the most important feature of footwear in preventing falls is the grip of the sole on the ground. Added to that is the need for good fit and thicker soles.

So what to do?

Keep mobile – exercise regularly – start walking, even if you use a walking aid. Maybe you need to start using one? Make sure that you can see and hear as well as possible.

A visit to a podiatrist for a biomechanical assessment is an important way to identify any underlying structural and functional problems. Treatment of any painful foot condition, such as corns and calluses, is essential and  information on the best shoes for you, will be provided.

Avoid higher heels, barefoot walking and slippers. Consider wearing trainers with a rippled sole. A word of warning though, some trainers have really ‘grippy’ soles and that can cause a fall!

Try to remove all loose carpet runners and potential hazards that you could trip over. Make sure the lighting in your home is adequate (most falls occur at home!).

It takes team work to prevent falls, so get any advice that you can, or share it with those who you know are at most risk of a fall.

Closed Kinetic Chain Exercise for Joint Rehabilitation – Jump for Joy!

Closed Kinetic Chain Exercise for Joint Rehabilitation was the title of a Rehabilitation Workshop that I was invited to yesterday. It took place at the University of the Witwatersrand Sports Science Institute and introduced  me to Reboundology and a quite extraordinary piece of kit called Kangoo Jumps.

Kangoo Jumps are a Swiss designed boot that almost defies description – the nearest that I can come to is – a Ski boot with an oversized doughnut lying on its side as a sole!

They have the ability to reduce the impact force to the ground by up to 80%. This patented Impact Protection System utilises the principles and practice of closed chain kinetics.

Basically, the difference between open and closed chain kinetics is that in open chain there is still some movement in part of the limb, this allows additional twists or rotations to affect other body parts. In the closed chain, the part is stabilised (eg foot or hand) against a hard surface. It’s actually more complicated, but this is what I understand at present. 

Rebound exercise is different due to the following factors: During rebound exercise; We are opposing gravity and acceleration: Acceleration in the vertical plane develops a greater G-force: All these forces come together at the bottom of the bounce: Cells have to work harder to maintain their position in space: This explains why trampolinists have extra unexplained strength.

Kangoo Jumps utilise these principles by allowing you to jump up and down, whilst concentrating your body weight through your centre of gravity.

I was able to test the theory in practice when we were put through an exercise session. I had a great time bouncing around the gym, being guided in various exercises. The first thing I became aware of was that my posture improved immediately, I stood up straighter and my core lower abdominal muscles were getting a workout! My heart rate went up quite quickly too. In addition, yesterday and more importantly, today, I don’t have any muscle soreness or stiffness.

Where you will be asking is the Science? There have been many studies worldwide, but there is ongoing research underway at the University of the Witwatersrand. Have a look on the website www.kangoojumps.co.za

Reboundology has also been the subject of considerable research by N.A.S.A

The application of this technology is for rehabilitation as well as strengthening. (You would be surprised who is using them!) For example they will improve balance, co-ordination and agility; improve foot alignment; increase overall muscular tone. They stimulate cellular bone rebuilding ability. The potential application in managing arthritis is an exciting thought.

Closed chain kinetics using Kangoo Jumpssseems to me to be offering a new clinical modality and challenge to our current way of thinking. You can be any age from 6 to 90! I can’t wait to start rebounding!

An interesting case: Sesamoid Fracture

I diagnosed a sesamoid fracture in a young woman this week. The presenting complaint, on Wednesday, was of “pain in the ball of the foot under the big toe joint for nearly 9 months, but 3 days ago (Sunday), whilst doing a long day shift the pain got really bad and only stops when I take weight off the foot.”

The ball of the foot was noticeably swollen, but not inflamed. However, when I applied light finger pressure to the area the pain increased and was particularly bad at one spot. The lady has a high-arched foot (pes cavus), but it is flexible not rigid. She is not overweight, but is very active everyday of the week -including some weekends – working long hours. She told me that she usually wears a low heeled shoe or sandal, but it had become impossible to wear slip-ons or ‘push-ins’ because of the pain. The only relief was to wear trainers with a thick sole. When the weight was removed by sitting or resting in bed there was no pain.

By applying a protective pad to the sole and the arch, with a cut-out around the painful area, painfree walking was possible. An X-ray was requested; both feet for reasons that I’ll explain shortly and a follow-up appointment was arranged for Thursday morning.

We met on Thursday and the X-ray showed a clear break in the lateral sesamoid. The pain was also worse because the padding had slipped backwards and out of position. By repositioning the pad, the pain was relieved again. I instructed her to use trainers as often as possible and suggested that she do the replacement padding herself. In addition I arranged for her to be fitted with an Aircast below knee walker, which she could borrow from the practice on Friday after work.

The treatment for this condition is mainly patience and removal of pressure. Which is why I decided on the Aircast. When we fitted the Aircast walking was immediately painfree. Now we both have to wait for the bone to fuse as one or even two bones.

There are two sesamoids under the ball of each foot. They allow a particular muscle to pull the foot down during standing and walking; they also survive a lifetime of bending at the ball (the first metatarso-phalangeal joint). In some people, one of the sesamoids is naturally bifurcate and can look as if it is fractured – called a normal variant -that is why I asked for both feet to be X-rayed. This fracture may heal in two parts also, which won’t be a problem.

Pain in this part of the foot is quite common. It is caused by excessive amount of shearing, compression or tensile stress over the joint. It can be associated with sports like golf and tennis. Starting running or training and doing too much or running in old trainers. Wearing old worn shoes, where the inner sole gets a deep imprint. It can be associated with rheumatoid athritis, or even standing on a ladder for long periods, when you aren’t used to doing that! Nearly always it affects people with a high arched foot who have over-used their feet.

Initially the bone and the joint under them become inflamed and that is called sesamoiditis. Ignore this and a sesamoid fracture may result.

Bunions – Should they go or stay?

Bunions create as much comment and discussion as they do pain for their ‘owners’. Let’s assume that your bunions are bony lumps. First ask yourself are they getting bigger and more painful? Being disappointed with the look of your feet is not reason enough for surgery. Possibly you have some underlying arthritis and the joint is painful at every movement and it is seriously affecting your quality of life. Rheuma-surgery,as it is known is becoming more appropriate nowadays. Another cause for concern is if the big toe is deviating away towards the smaller toes so much that your foot is beginning to look like a tennis racquet.

Whatever the nature of your problem, if you do decide to undergo surgery I believe there are some basic truths to come to terms with. Perhaps the most basic is the most obvious – make sure your surgeon is a specialist foot surgeon – not one who includes foot surgery with the rest of his/her practice.

Then you have to fully understand and accept the conditions surrounding the surgery. This usually includes at least six weeks of careful rest, individualised treatment and immobilisation, plus the general life disruption. It’s my opinion that most “disappointing” surgical outcomes are the result of patients being unable or unwilling to fully comply with the post-operative care requirements.

So what to do about your bunions? Try every conservative measure that you can to preserve your feet. if your life has become interrupted and painful because of your bunions then DISCUSS with your surgeon all about the procedure and after care before you go ahead. Or maybe don’t!

On Safari – AFLAR Rheumatology Updates – Nairobi

Back from the AFLAR Nairobi Rheumatology Updates. Hard work, but enjoyable and successful.  I presented my “Foot Problems in Arthritis” talk to the Allied Health Professional’s Workshop and the formal Regional Rheumatology Symposium.

An ‘on safari’ report was intended, but my laptop was attacked by Trojan Horse and worm viruses, after picking them up from the generic computer we used for the workshop. Fortunately the IT expert at my hotel was able to clean the flash drive and I just shut the computer down. Now all is clean and healthy again.

Andrew Clarke receiving a gift from Dr Andrew Juma Sulah, National Chairman, Kenya Medical Association

The big ‘take home ‘ message of the workshop was the need for team work in assessing and managing the effects of arthritis in any form.

The interaction between the physiotherapist, occupational therapist, rheumatology specialist nurse, podiatrist and rheumatologist; plus all the other health professionals, was highlighted by the team that came to Nairobi from Glasgow.

Their big message was that the centre of focus must always remain the patient. They also showed how their individual professions have developed extended scopes of practice to enable a massive reduction in waiting lists in Scotland, due to the screening interventions that they are allowed to do.

Despite the apparent skills shortage in Kenya – there is only one rheumatologist in the whole country – there are many skilled and enthusiastic allied health professionals plus other doctors such as GP’s, physicians and orthopaedic surgeons interested in getting involved with managing arthritis. I met many of them during the week.

Delegates at the Regional Rheumatology Symposium

Additional talks were on ‘Arthritis, feet and podiatry’ and ‘Footwear for problem feet’. In the practical sessions, delegates were shown how to make a basic insole and use padding onto the foot and into the shoe. More on this another time.

Oh yes. Traffic. I will never complain about Johannesburg traffic jams or driving again. The rush hours are gridlock in extremis; unbelievable.

Thank you AFLAR for the invitation and Roche Pharmaceuticals for the financial assistance.
