Shakespeare? What a pain!
I was lucky enough taken to the Old Vic recently by an old friend, to see Kevin Spacey playing the lead role in Sam Mendes’ production of Richard III. I’m not generally a huge Shakespeare fan (memories of watching Macbeth at the National Theatre when I was studying it at GCSE put me off somewhat; and I found Jacobi’s Lear unconvincing this summer) nor am I a particular Spacey fan; but this show really blew me away. I was enthralled and barely glanced away from the stage for the entire three hours.
But three hours is an awfully long time for a man to play a twisted hunchback; the King is rarely offstage and the physicality of Spacey’s performance was quite extraordinarily compelling and consistent. He played a man in pain extremely convincingly; in fact I’d be amazed if he wasn’t genuinely in quite some significant pain by the end of the production, and I wonder if I was the only audience member relieved to see Richard hoisted aloft by his ankles at the end: at least he finally got some traction to relieve his poor, tortured spine!
After all, Kevin Spacey wouldn’t be the first actor to be left crippled by Shakespeare. I rather assume this story is apocryphal, or at least that the wording has been altered over the years; but according to Antony Sher’s “Year of the King”, at the end of the original production of Richard III, Burbage told Shakespeare “If you ever do that to me again, mate, I’ll kill you.” Somewhat later, in 1972, Robert Hirsch of the Comédie-Française apparently found some sort of solution: his Richard limped on alternate legs from night to night!
Simon Russell Beale managed a five-month run as Richard III in Mendes’ production for the RSC in 1993; but just three days after it transferred to the Donmar Warehouse, he was forced to retire and to have an operation on a prolapsed spinal disc. The same thing happened to David Tennant in 2008 during a run of Hamlet: after a successful summer run in Stratford-upon-Avon, the production moved to the Novello Theatre and Tennant ended up in surgery.
Given how slowly spinal discs go wrong, it seems unlikely that Shakespeare and his directors can be completely blamed for this spate of injuries to leading men. They probably had some degree of back pain before they took up their roles. However, there’s no doubt that the physical demands of playing a role which requires extreme postures to be maintained for prolonged periods, will cause a degree of soft tissue deformation and also of extreme concentrations of compressive stress on the spinal discs. Moving and changing position regularly causes compressive stresses to alter, and it is thought that this assists with disc nutrition (which is why it forms the basis of Sarah Key’s “pressure change therapy” theory); the reverse is also true, with prolonged relatively static postures, particularly extreme postures, effectively reducing the discs’ nutrient supply and causing damage.
So my pleasure in watching this extraordinary production was tempered somewhat by the thought of the damage the leading actor was doing to himself in his effort to provide a superb experience for the viewing audience. Mr Spacey, I do hope you have a good physio!
The problem with leg raises
I went to my usual circuit training session the other day, run by British Military Fitness. It's a lot of fun: a fairly tough workout with a lot of cameraderie and competition, and outwardly no-nonsense (but actually very humorous) instructors. They will push you as hard as you want to be pushed, and often very slightly harder.
I love the sessions; but as a punter, you have to remember that most instructors aren't psychic. They will always ask if you have an injury, and will always offer alternative exercises, but they can only help you if you tell them that there is a problem. This is something that can be tricky unless you are quite confident in your own body and its capabilities (not something I generally struggle with too much, but I've had a lot of practice!). It's easy to let your competitive side take over, and to start competing in exercises you're not familiar with. Consequently your form can go to pot as you try to complete that 20th rep before the guy next to you: if you're doing a demanding exercise, that's an easy way to get injured.
One of the exercises I really dislike in that situation is the leg raise, where you lie on your back with your feet together and wave your legs in the air, with an obtuse angle at the hips. It's an exercise that's supposed to work the lower abdominals and tone the tummy.
The reason I dislike this exercise so much is that the majority of people find it tough to control their torsos in this position. I have a strong back and good awareness of trunk control, but in this position I find it really hard to stop my low back from arching. That's because the hip flexor muscle psoas major is being put under a lot of stress to control the momevent of your legs at the hips. Psoas starts at the sides of your lumbar vertebrae (T12 to L5 to be precise) and goes down to the lesser trochanter of the femur. When it contracts, these bones are pulled together.
When your back is being correctly stabilised (by, among other muscles, lumbar multifidus and the deep abdominals), the spine is braced to pull your femur forwards and up, so your hip flexes and your legs move up and down. That's the plan; so far, so good.
But when your back isn't correctly stabilised - either because of weakness or pain around the low back, or because you're focusing on banging the numbers out rather than on protecting your back properly - your low back can arch and the vertebrae shear forwards towards your hip rather than your hip moving towards your spine in a controlled manner. I've mentioned forward shear as a bad thing before, when I talked about spondylolisthesis. So with 80% of the population suffering from back pain at some point during their lives, I'd suggest avoiding this exercise if possible, not because it is intrinsically bad but because many people will do it badly, particularly in a competitive setting.
A good alternative exercise, which will strengthen the deep abdominals safely, is the reverse curl. Lie on your back with your hips flexed to 90 degrees. Your knees can be bent or straight, but your hips must not drop below 90 degrees throughout the exercise. Using your abdominal muscles, pull your legs towards you so that your bottom lifts off the ground. Hold for a second, then lower it slowly back to the starting position. If you feel that your back wants to arch as you return to the start, try putting your hands or fists under your bottom (not your back) as this will encourage you to keep your low back in contact with the ground at all times. This way you will still be working your lower abdominals and your psoas, but there will be no risk of a shearing force damaging your back.
I should mention that after quietly explaining my concerns about this exercise to the excellent BMF instructor, she asked me to show the class and to post about it on the BMF Facebook page. So Annie, this one's for you!
Knees and pelvises - what to do about them
In my last post, I explained how having a stiff and unyielding pelvis can be a real pain in the knee. But it's not fair to leave you hanging, so here's the solution.
The first step is to release the tightness in the low back and pelvis joints. To do that, you need to release the surrounding muscle spasm and then stretch out the muscles and ligaments that are holding the joints so stiffly. This will help to flush out the joints, encouraging the synovial fluid inside them to become more liquid and less viscous, allowing more nutrients in and more waste products out.
At Victory, I release the low back and pelvis joints using my feet, in line with the Sarah Key Method. This is quick, effective and quite gentle, and it gives a "kick-start" to the exercises, which allow you to maintain and improve on the changes we achieve in the treatment session. However, in many cases it is also possible to make significant gains with just the exercises.
Therefore, for home treatment, the two exercises I really recommend to release the low back and pelvis are the appeasing exercise and a variation on the back block exercise. Alternate them, doing three sets of each exercise for 30 seconds each, 2-3 times per day, and your pelvis should soon start to free up.
The variation on the back block exercise is that instead of placing the block horizontally under your pelvis, this time I'd like you to place it vertically - so that it points down towards your feet. The upper end should still be under your pelvis though, not under your low back. Then, once you've lowered your bottom onto the block, instead of sliding your feet away from you, just drop your knees apart, something like this picture from the Egoscue website. If your adductors (inner thigh muscles) are tight, you may well feel a stretch there; if they're loose, you'll feel a stretch at the back of your pelvis as the "wings" stretch apart. Hold the position for 30 seconds before drawing your knees back together, removing the block from under your pelvis, and resuming the appeasing exercise.
The second step is to stretch your hamstrings, with particular emphasis on the distal (knee) end. Traditional hamstring stretches, where you bend forward with knees straight, focus on the proximal (hip) end of the muscle; but people with knee pain tend to be tighter near the knee.
To emphasise the distal end of the hamstring, you need to start with your hip fully flexed, and then gradually extend the knee. So, as demonstrated here by the lovely Graeme, stand in front of a chair (preferably one without wheels!) and place one foot on the seat. Bend forward at the torso and get your chest right onto your thigh. Hug your thigh tightly with both arms, so that your chest stays attached to it throughout the stretch.
Gradually lean your bodyweight backwards so that your raised knee starts to straighten out. Go as far as you can, until you feel as though your chest wants to lift, then hold the position for 10 seconds. Release slightly and then lean back into the stretch for a further 2 x 10 seconds, then repeat with the other leg.
Another really useful treatment is massage. You may well find that you have tight, sore trigger points in your buttocks, hamstrings, adductors and/or iliotibial bands (fascia that covers the outer thighs). Stretching can be significantly aided by massage to get rid of these small localised areas of muscle spasm. You can either get someone to help you with this (if your helper is not a trained therapist, ask them to start gently and work their way in: kinder and more effective than an aggressive pounding!) or you can self-treat using a foam roller. I really like this comprehensive YouTube video from Alex Poole that shows some effective foam roller techniques.
If you would like to get rid of your knee pain (whether due to the pelvis or not!) please e-mail me to arrange a session and see how I can help you.

Toe bone connected to your foot bone
Foot bone connected to your ankle bone
Ankle bone connected to your leg bone
Leg bone connected to your knee bone...
OK... you've probably heard a verson of James Weldon Johnson's spiritual somewhere before, and while it's not technically accurate in its anatomy, the concept (that everything in the body is linked and works together, rather than a body being a collection of separate joints) is one I reference a lot.
Today I'm going to talk about the link between knee pain and your pelvis - or, as JWJ might have put it, your knee bone's connected to your back bone.
The large muscles of the thigh - quadriceps at the front, and hamstrings at the back - are biarthroidal muscles. This means they cover two joints, the hip and the knee. The quadriceps work to flex (bend forward) the hip and extend (straighten) the knee. The agonist (opposing) hamstrings work to extend the hip and flex the knee. Both groups of muscles attach to the pelvis at the top, and to the shin (tibia and fibula) at the bottom.
When you walk, and more violently when you run, your quadriceps pull to swing your leg forward, as your hamstrings pay out at a controlled rate to prevent you from hyperextending and jarring your knee, facilitated by a slight backward rotation of the sacroiliac joint in your pelvis. As your foot lands, both the quadriceps and the hamstrings contract to control your landing, and then the hamstrings begin to pull to provide the power to propel you forward over your landing foot.
So far, so good. Everything is working normally; and normal functioning of joints with no structural deficits will cause no pain. But what happens when there is a glitch somewhere in the system?
The sacroiliac joint of the pelvis (between the sacrum at the base of the spine and the iliac "wings" of the pelvis) is a pretty common source of problems. There are many reasons why the sacroiliac joint can stop functioning properly - ranging from an impact injury such as a car crash or a fall, to a general poor posture which involves staying too still and not using the joint enough - but the effect generally is that it stops rotating effectively. When this happens, it impacts on the hamstring's ability to pay out in the swinging leg, and the joint's ability to absorb shock when the foot lands.
When the hamstring doesn't pay out effectively, your body will respond by altering your gait so that it doesn't have to. You'll take ever-shorter strides and your running gait will alter from a smooth glide forward to a jerky bob-up-and-down movement, which requires more shock absorption from the sacroiliac joints... and thus the cycle is perpetuated. And if the sacroiliac joints can't absorb shock properly - well, the shock of impact has to be absorbed somewhere, and the knee (particularly the patellofemoral or kneecap joint) is often the victim. In my experience, this is a very common cause of knee pain, especially in runners.
What can you do to break the cycle? You need to reverse it: get your pelvis moving, and your hamstrings flexible. I'll explain how in my next post, so watch this space!
If you are struggling with knee pain when you run, it may well be linked to a dysfunction at your pelvis. Please contact me for assessment and treatment.
Mobilising the Military
Today I took a trip to RRU Aldershot. This is the flagship of the military Regional Rehabilitation Unit network and only opened six months ago, so I was intrigued to see it; but I was also there to do some work.
As I've previously mentioned, in 2004 I designed and carried out the first piece of formal research on the Mobiliser bed, a passive spinal mobilisation device created by engineer David Newbound, the owner of the Back in Action chain of ergonomic furniture shops. My pilot study bore out the manufacturers' claims that the Mobiliser could help to improve range of movement in the spine, improve thoracic expansion and reduce pain levels in patients with back pain - and I've been using the Mobiliser ever since.
Finally, it looks as though I am winning in my battle to have the Mobiliser recognised by the military as a therapeutic tool, an adjunct to physiotherapy. The RAF have just bought a batch for use in their RRUs - where more seriously injured servicemen go for periods of intensive rehabilitation - and it is anticipated that the Mobilisers will be awarded NATO Stock Numbers or NSNs very soon, meaning that all military medical rehabilitation departments will be able to order Mobilisers.

My job today was to demonstrate the use of the Mobiliser to the RRU staff who will be responsible for introducing it to their practices, along with David Newbound and senior MOD physiotherapist Dr Cathy Daborn. I also explained my theories as to how it acts on spinal mechanics and helps to restore normal motion.
Essentially, the spine is able to perform large global movements such as bending and stretching, leaning forwards, backwards and sideways. But it does this with the help of a lot of very small accessory movements between the vertebrae, which slide and tilt and twist on each other infinitesimally in order to produce the obvious, big movements. Stiffness occurs when the accessory movements - the slide and the tilt and the twist - are reduced, by disc dehydration, joint disruption such as injury or by muscle spasm.
I believe that the Mobiliser - with its regular, fairly gentle but relentless repeated movements - calms muscle spasm and then (using the gravity-induced backward shear I discussed in the last post) passively pulls the joints apart to restore the sliding accessory movement. Over time, with the muscle spasm reduced and joint mobility restored, pain is reduced and function improved.
What the Mobiliser doesn't do - and this is why, particularly when there are rotational components to a spinal problem, you still need a therapist to mobilise the spine with hands or feet - is to restore the twisting accessory movements. After all, it's a machine, and not capable of intelligent touch or clinical reasoning. But it is a very useful adjunct to manual therapy and exercise therapy, and I believe is a valuable tool in the treatment of chronic spinal stiffness.
If you're interested in discussing using or hiring a Mobiliser, the best option would be to contact Back in Action, or pop into one of their shops to try it for yourself.

Why use the back block?
I had an e-mail this week from a blog reader who asked whether the Sarah Key exercises I've blogged so far would be good for spondylolisthesis.
Spondylolisthesis is a condition which affects 3-6% of the population in which one vertebra - most commonly the L4 or L5, at the bottom of the spine - slips forward on the one below it. Left uncontrolled, it produces a more exaggerated curve of the low back, like those you often see in men with really big tummies or pregnant women. The grade of spondylolisthesis is determined by an X-ray to see how far the upper vertebra has slipped - a grade I being a forward slippage of 1/4 of a vertebral body, grade II being half, and so on. Surgeons tend to get involved with grade II+ spondylolistheses as the slippage is more likely to be a danger to the spinal cord.
There is a fair amount of evidence in the literature for strengthening the core muscles of spondylolisthesis patients, particularly the transversus abdominis which acts like an internal corset, and the multifidus which acts like the guy ropes of a tent to shore up and stabilise the slipped vertebra. I'll go through some useful exercises for these in future posts as they are excellent for any form of instability, but incidentally this is one situation where I think exercise methods such as Pilates can be really useful.
As well as core exercises, I really rate the back block for spondylolisthesis patients. Traditional physiotherapy extension exercises are carried out from the prone (face down) position, where the patient pushes up onto elbows or hands to extend the spine. I don't use this for spondylolisthesis patients because gravity, as you can see from the top diagram, acts on the vertebrae to produce an anterior (forward) shear - exactly the same force that causes spondylolisthesis! Lots of physiotherapists have therefore moved away from prescribing extension exercises to spondylolisthesis patients.
By contrast, however, the back block exercises are done in a supine (face up) position. This results in gravity pulling the vertebrae towards a position of backward shear, as you can see in the lower diagram - and thus into a more neutral position away from the spondylolisthesis slip.
The effect of this tends to be (gradual, cumulative) better alignment of the spondylolisthetic segment, and also reduced muscle spasm and reduced pain.
Of course, not every case is that simple: longstanding spondylolisthesis problems often lead to altered muscle control and movement patterns, as you start to compensate for the discomfort of the injury. Using a back block doesn't replace a proper assessment and treatment plan in every case. But if your physio isn't already getting you onto a back block, it might be something to discuss.
Please feel free to ask questions - either here on the blog or by e-mail - or get in touch to arrange an appointment.
Sarah Key Method - Back Block
Time to get back to backs!
This exercise is another of Sarah Key's, and is great for stretching your low back. You'll need what Sarah calls a back block; they're also known as yoga bricks. Roughly the size of a house brick, they come in a variety of materials including wood, bamboo, cork and foam - I usually use one made of solid foam, though in an emergency I have also been known to use a hardback copy of a Harry Potter book!
When we spend all day with our spines in an upright position (sitting, standing, walking, running), gravity combined with our bodyweight squashes our spinal discs, and over the course of the day they flatten out a bit. It's not unusual to be 2cm shorter at the end of the day than you were at the start. Generally, the discs rehydrate and plump up again overnight when you're lying flat, but over time - with age, or particularly with injury - the flattening starts to have a greater effect than the rehydration, and you develop stiff spinal segments.
Sarah's theory is that this process is reversible if you regularly take steps to decompress your spine, and this is where the back block - coupled with the appeasing exercise I described before - comes in.
-
Lie on your back on a firm surface such as the floor, knees bent so that your feet are on the floor, and feet and knees together.
- Squeeze your knees and buttocks together. Keeping them squeezed, roll up your spine, curling your bottom off the ground first, and - bone by bone - then your low back, mid back and upper back, until your weight is on your feet and shoulders.
-
Bone by bone, roll your way back down again, trying to make the space
between each bone as long as possible, and making sure that when you reach your pelvis, the left and right sides hit the ground at the same time.
- Make sure your knees and buttocks are squeezed together, and roll all the way up to your shoulders again, bone by bone.
- This time when you are at the top, slide your back block underneath your pelvis (NOT under your low back) and roll your bottom down onto it. The block should be horizontally aligned and on its shallowest side.
-
Slide (don't lift) one foot along the ground and away from you, and then the other. Allow your ankles to relax and roll outwards. Relax your calves, then your knees, then your thighs, buttocks, low back...
- Let your arms roll outwards so that your palms face the ceiling, and relax completely for a minute.
- Then slide one foot back up towards you, and then the other.
-
Squ
eeze your knees and buttocks together, and roll your way up off the block (at first this may be sore; don't worry, this is quite normal and it does get better!)
- Slide the block out from underneath your bottom, and roll down just as you did before.
- Now do 30 seconds of the appeasing exercise, and repeat the whole thing three times.
NB - any discomfort you feel on curling up off the block should fade quickly and should improve over the first few days of practising this exercise. If it is too painful, or remains significant for more than a week of doing this, you should discontinue the exercise and get your back assessed. (Of course, I'd recommend that you see a Sarah Key-trained physiotherapist...)

Sarah Key Method - Appeasing exercise
Moving on from last week's diversion - back to the back pain!
This exercise from legendary Australian physiotherapist Sarah Key is suitable for virtually anyone's back, and is the first exercise I teach my patients who have low back problems. The key is to be very subtle with your movements - in this instance, less is definitely more. The idea is to gently appease the low back muscles and coax them out of spasm, muscle spasm being the body's natural - but in this situation unhelpful - response to pain.
If you jerk or move too forcefully while doing this exercise, you are likely to stimulate the stretch receptors in the muscles, which could potentially make the spasm worse. But if you can keep your movements smooth, and "under the radar" of the stretch receptors, then it will really help to soothe your back pain.
-
The first step is to lie on your back on a firm surface - a folded blanket on the floor is fine, or in my therapy rooms I use a yoga mat.
-
Pull your tummy in gently, as this supports your spine, and bring one knee up to your chest. Hold the knee in the same hand - i.e. if you have lifted your right knee, hold it in your right hand.
-
Keeping your tummy pulled in, bring the other knee up to join the first, and hold it in the other hand.
-
Cross your ankles, and drop your knees apart, still holding them in your hands. Let your tummy relax.
- Producing the movement with your hands, move your knees gently back and forth, left and right, until you find that your weight is over the sore part of your back. This is where the muscles need to let go. Oscillate your knees gently and repeatedly over this area - I describe this to my patients as "ironing the spine" - for a minute or two until the muscle relaxes and the pain subsides.
- After a minute or two, use your hands to bring your knees back to the middle, pull your tummy in gently, and then lower first one foot to the floor and then the other. Rest for a minute or two and then repeat twice more.
- On the second and third repetition of the exercise, you may find that the sorest spot in your back has moved a bit. Hunt around until you find it; but remember to keep the movements subtle and gentle.
If your back is really sore, you may need to do this exercise very regularly, perhaps as often as every hour at first. Some people also find that heat is helpful, so you may also want to try using a hot water bottle on your back (obviously, all the usual precautions apply here: please don't burn or scald yourself!)
If you can't relieve your pain by yourself, then of course please do e-mail me for an appointment. I am at the Foundry on Mondays and Tuesdays, and at the Back Shop on Wednesdays and Thursdays.
Thanks to my lovely model Graeme at The Foundry - the cheque's in the post!
Sarah Key Method - Stage 1: Stiff Spinal Segment
Back in September, I started a series of blog posts detailing Sarah Key’s theory on back pain. I wrote about spinal anatomy and explained how the spine should work in a “normal” situation.
Now it’s time to start talking about what goes wrong with backs. Sarah’s theory is that back pain occurs in five consecutive stages.
She simply calls the first stage a “Stiff Spinal Segment”. Not a sexy or particularly gripping description, I’m sure you’ll agree; but most people have at least one, and it is a condition which underpins all the later and more devastating types of back pain.
As I mentioned, spinal segments (each segment consisting of a vertebra and the disc that sits on top of it) are barely viable at the best of times, so arduous is the journey from spinal canal or vertebral endplate to nucleus and back again, that fluid and nutrients have to take.
The many potential obstacles to the nutrients reaching the nucleus and waste products then being expelled include:
• Unremitting spinal compression – for example, staying in one position for too long, or carrying a heavy load for a prolonged period.
• Weakness of the tummy muscles, which allows uneven compression of the spinal segments.
• Chronic protective muscle spasm, which happens when you are in pain.
• Injury – a fall, for example, which can cause a traumatic rupture of the vertebral endplate.
The problem in all of these scenarios is that the disc is compressed (thus squeezing out fluid) but not unloaded again. It’s therefore not able to suck in fluid and nutrients to replace the fluid that has been lost. As a result, the all-important proteoglycan synthesis is not stimulated and thus the disc begins to become dehydrated and to flatten. In turn, the spinal joints then become stiff, which is the point at which you are likely to notice it, because stiff joints hurt when you try to make them do perfectly normal everyday activities, such as putting your socks on.
Manual therapists such as physiotherapists can feel these stiff joints when we palpate, or poke, your spine. (That’s the bit where we make noises like a car mechanic finding a dodgy spark plug and you start to worry for the safety of your wallet.)
The good news is that – with a bit of manual therapy and a lot of home exercise - a stiff spinal segment is a reversible condition. That is, it is possible to get the joints moving again, and thus to promote better disc metabolism; it may even be possible for the discs to rehydrate. In my next blog post, I’ll explain the basic exercises that everyone with a stiff back should be doing to help themselves.
In the mean time, I am at the Foundry on Mondays and Tuesdays, and at the Back Shop on Wednesdays and Thursdays. Please e-mail me for an appointment.
Harley Street Victory
Exciting news: Victory has just opened a therapy room in The Back Shop, at 14 New Cavendish Street, London W1G 8UW.
The Back Shop has recently come under new management as it has been taken over by David Newbound and his team at Back in Action, the chain of ergonomic back care shops which sells everything to do with back care: back supports, chairs, desks, beds, pillows, writing slopes - and my favourite, the Mobiliser bed. I have known David for many years, since I undertook to research the effectiveness of the Mobiliser (about which, more in my next post) and have been working out of the therapy room in his Marlow shop since I left the Army.
David
invited me to visit him at the Back Shop as soon as he acquired it, a few weeks ago, and I instantly fell in love with the building. It needs a lot of work if it's to be restored to its former glory, but he and his team have some lovely ideas which will hopefully come to fruition soon. And in the mean time, the shop is still open and David has been adding some of Back in Action's signature products.
As the Back Shop is in the heart of the Harley Street medical community, David's aim is to ensure that everything available in the shop is of the highest quality - and that includes the treatment. So I was delighted when he approached me to ask if Victory would be interested in using the treatment room.
I am currently using the room just for physiotherapy, on an "as-and-when" basis; but from January will be available to offer treatment on Wednesdays and Thursdays. Please e-mail me for an appointment!
