What exercises were you recommended initially Hazel?

Is there any change in the pain - in terms of intensity, frequency, when it comes on, how long it takes to go?

Any change in mobility?

hi hazel, rach hasnt been able to get on for a few days due to work commitments.

we were talking about it at weekend though, shame you didnt mention it when she was there with james!  shes back again in just under 4 weeks though!

Rach - thanks for the exercises last week.

I have them all in hand.  But please remind me: you gave me one to introduce where I lie on the floor, knees bent, and find my natural lower back postion, brace but do not arch.  How long do I hold this and do I rep it?

Hi Rach

I have been told the problem with my right shoulder is a tear in the shoulder capsule.  I have been advised to avoid overhead movements, pull downs etc for 6 weeks and was given some exercises, basically to stretch the shoulder too.  I am about 4 weeks in now and not much improvement in the pain.  Can you recommend any other exercises/ treatments please?  Maybe easier to ask you next time you come to see James!

Thank you.

 
HI Hazel
I would need to know exactly what you have torn first. The shoulder capsule is too general a term to be able to understand what the damage being suggested is.
Can you get an exact diagnosis?
Probably best to see you when I am next in too, grab me then.

Ok with the brace technique it is advisable to practise this with low intensity contractions of a single rep held for about 6-10 seconds to start and then progress to holding for longer. Then begin to vary the intensity also to higher intensity with a shorter hold again. Breathing during the brace.
The idea of this brace technique is for it to become second nature in all you do during daily living and during exercise so you need to be able to perform it in a variety of ways. For example while you are driving or sitting at a desk the intensity will be lower but for a longer duration, yet during training it will be a more intense contraction for a shorter length of time.
Start just by nailing the technique first which may 'seem' to be an easy thing to do but many of us struggle with the perfect technique on this which is why lower back pain is so common.
Many people do not realise that when they 'switch on' their abs, they are in fact 'switching off' the multifidus in the back which are as much a stabiliser of the trunk as the abs are.
Hope this helps.
Love your commitment James! :)

Difficult to explain in text, but turning head each side with arms out at shoulder level and outing alternate hand up.
Stretching arm down while holding small weight
back against wall, chin to chest
lots of stetching, have had longterm neck probem too.
Avoid weight training exercises that use overhead movement
Still get shooting pains in hands
Painful to do front raises.
Lying on the shoulder is painful too.

Thanks

hi mate, might be a day or so untill rach can get on, as shes working away at the moment, but will let her know about your question.
 
where do you live mate?  with you having back problems and being tight on the shoulders, it would be well worth the cost of you getting a full screen done, more than possible that both can be helped!

Hi
Ok I am afraid as with most queries on here it is imortant to understand I cannot make a completely accurate response without actually screening you in person. What I can do is maybe give a clearer idea of the types of issues that can be affecting you biomechanically.
One very common issue is the protracting shoulders you describe due to a number of reasons like sitting at a desk, driving a lot or poor posture.
What most people will do is attempt to stretch the areas that appear to be 'tight' which is completely understandable. The problem is knowing if the shoulders are 'tight' or in fact in spasm. If a muscle is in a sub-clinincal spasm the worst thing to do is try and stretch it. It could be in spasm as it is wanting to protect the joint area for some reason and so trying to stretch it will just compound the issue.
So we recommend first using a muscle release technique that can have profound and sometimes an immediate affect.
Using the 20/20 technique 4 sets 4 times daily is the usual recommendation.
The problem is that there are likely to be other biomechnical issues combined with this one so I strongly suggest you find a Biomechanics coach in your area.
If you have no luck come back to me certainly before you get any medical treatment.

Let me pose the question:
Can you load rectus abdominus dynamically without flexing the spine?

Re:Biomechanics Q & A: Post your questions here - 07 April 2010 23:09
Wrist, elbow, shoulder and arm pain is most commonly due to some sort of Biomechanical dysfunction. Often a tethered Madian nerve can create discomfort anywhere along its path or just off it.
It is a very common cause of shoulder injuries and is in fact a very simple problem to solve.
Do you want to know how to test it and mobilise it?

Ok, well if you're still reading I guess you do!
So you need know that it runs down the side of the neck to the front of the shoulder on the same side. Down the front of the arm, across the inside of the elbow and the palm of the hand to the thumb and 2 fore fingers.
To test if it is tethered stand facing a mirror so you can judge that your shoulder stays down-(this is important because if tethered, when lifting the arm, the shoulder may rise sub-consciously to relieve the tension in the nerve) it is important to move slowly too as nerves are visco-elastic and do NOT like to be stretched and certainly NOT quickly.
Keeping the shoulder down flex the wrist/hand back and turn your hand backwards with palm facing down to the floor so your fingers are pointing behind you (note:keep thumb and fingers as straight as you can to create the tension and just check your shoulders in the mirror are both still held down).
If at this point you feel tension, tingling, heat or any sensation, while trying to avoid actual pain, at any point along the route of the Median nerve STOP-now keeping your hand in that position shrug your shoulder up to your ear. If the tension disappears then this demonstrates it must be caused by Median nerve tethering.
To mobilise it you stay in that position and add and release tension, WITHOUT PAIN, by extending and flexing the wrist 15 times twice and t be done twice daily-certainly before lifting weights. You may feel the tension ease off if so then you can take this to the next level.
The next level is also for those who didn't feel anything at the first level. At this point keeping the wrist flexed now SLOWLY take the arm out to the side ( NOT backwards or forwards of the body) until you find some tension and then repeat as before by lifting the shoulder to see if the sensation goes away. If it does then you mobilise here by doing the same action of flexing and extending the wrist to mobilise the nerve under the fascia.
This can have immediate relief or for some it may not be so quick and can take up to 6 weeks but in our research we have proved that strength can be increased by 14% just from 2 sets of nerve mobilisation.
Give it a try and let me know what you think or if you have any biomechanics questions ... Good luck!!

"

Hi Rachel, you don't say whether you should turn inwards or outwards with the palm facing the floor. I definitely get more nerve pulling sensation turning my palms inwards as I turn them towards the back. 

This is good stuff, I definitely have a tethered median nerve then. Thanks for posting this information and help.

To mobilise it you stay in that position

 
Sorry, this is important for me! :) do you mean stay in the shoulder shrugged position when you do the flexing of the wrist?

HI
Sorry I wasnt clear in my first description and I am glad you asked Nev.
Turn the hand outwards and back and you only shrug to test that it is median nerve that changes the sensation. (If the sensation doesnt go away it could just be tension in the soft tissues)
so replace the shoulder down into the depressed position to mobilise with the wrist flexing.
Just remember not to take it into pain. I recommend you dont do it as soon as you wake up even thought that is when you feel worst.
Let your body wake up for about an hour first.
Let me know how it goes...
;)

Sorry Rachfit I'm being really thick here.. I just want to make sure of what you mean by wrist flexing.. Do I keep my fingers open i.e.  palm facing the floor and literally move the hand up and down as far as it will go in each direction? Sorry!

It is ok you can ask as much as you need to:
So with the arm by your side you flex the wrist so that the palm is down and your nails to the ceiling. Fingers can be together or spread apart just so long as they are as straight as you can keep them.
The fingertips should point round to the back of you and then (if no tension found here) when you take the arm to the side, your thumb should be travelling away from you ahead of your other fingers.
Let me know if this helps

These are really good Rachel, thanks for posting. My hands particularly my right one feels weak in the morning. Today my median nerve pain ( I use that word loosely since it doesn't hurt intensely) is bad, I did some gardening over the weekend, but not that much yesterday, I have also been doing the exercises, so not sure if its those that have aggravated things. Its a little calmer after this mornings problems, but even with my arm across me while sitting if I make a fist it really tugs on the nerve and the tug is felt in the hand. Also some movements of the hand feel like they are plucking the nerve.
 
I've made such good progress on the bench that I'm concerned this could mean the end for weights, but I have to say, my hands don't feel bad following a workout. Mostly its at its worse in the morning and I know I sleep on my hands sometimes unconsciously and don't if thats why every morning its so bad.. I don't want to be a 155kg bencher who can't open a jar of jam!
 
Should I persist with the mobilisation exercises twice a day?

Hi Rachel,

Sort of related to biomechanics, but im having trouble finding out which nerve (and from which Cx vertebrae) supplies feeling to the side of the face and head (area including; cheek, cheek bone, temple and side of the head over the ear).

I have mild tingling all over that area after a car accident last year. I believe its some sort of impingement from the neck.
Never had anything done, as after having a brachial plexus traction injury (saw a consultant) a few years ago I realised little could be done or help. 
Trying to find a good neck specialist or sports physio/osteo.

Thanks in advance

Just to stress that when you are doing the nerve mobilising you shouldnt be taking the movement into pain, just until you feel tension. If this is the case continue with them twice daily. If you are finding that you are going to the point of pain in doing them then you should reduce the range and move very slowly into the 't' of tension only.
It could be that there is some muscle spasm in your pelvis and/or shoulder too so I will be posting a muscle release technique on here next that you could add into your routine.
If there muscle spasm this can cause the nerve tension so thre muscle release is necessary to enable you to properly mobilise the nerves.
As I said it isnt easy to help doing this online but I will continue to do what I can here bit by bit.
Keep me informed!

Hi I've been told this is the right place to ask about injuries

The inside of my elbow (see pic below) has been giving me problems for the last couple of weeks but got alot worse today. Its not a massive amount of pain but I'd say it's really uncomfortable more than anything.



Sorry about the huge picture.
Anyway it's kind of a click whenever doing pressing movements (Benchpress seems worst). From a quick google search it looks like it could be something called "Golfers Elbow" I'm really hoping this isn't a permanent injury because I'd be gutted that I cant crack on with parts of my training

Any advice on what to do about it would be great. Maybe stick with light weights or totally rest it? Would it be woth going to see the Doctor and maybe buy an elbow support?

Thanks in advance, Burney.

HI Burney
This was intended more as a Biomechanics Q&A rather than an injuries Q&A but I seem to be attracting alot of injured people onto here. I guess those who do not have injuries as such do not seek advice and yet the training I deliver is injury prevention training, based upon instrinsic Biomechanics. This involves stacking the body up correctly 'before' the injury occurs by understanding how the pelvis, spine, nerves, muscles and joints affect each other.
Life is asymmetrical and so asymmetry in these ares is common and usually leads to aches, pains and problems eventually causing injuries. This is more apparent with those who train with weights as we are strengthening ourselves in incorrect Biomechanical positions.
The problem is people are completely unaware of any Biomechanical dysfunction until they actually become injured and dysfunction is extremley common.
 
Anway you asked me a simple question and as I always please understand it is not easy to deal with these issues just in posts on MT but I will do my best with what I have and what you tell me.
What I suggest is that you have a good read back on this thread to the Median nerve release and try this first-please read the technique thoroughly before you try it and let me know what happens and what you feel.
Maybe lighten your load for a little while and take care during all of your training avoiding anything that causes discomfort.
Keep in touch!
;)

^^ Thanks for the reply Rachel Apoligies for putting it into the wrong place.

Good read in the last 4 pages. Very clever stuff. Will have another look through it sometime and try to understand it all better.

For the movement you mentioned I didn't really feel much tension or pain in the elbow. It seems to get me the most if I put my hand flat on the back of my head whilst pushing with a light amount of force. It's really hard to explain the feeling.

Cheers again for replying. Burney.

Ok well just remember you are not trying to get 'pain', just a comfortable stretch or some kind of sensation to indicate tension.
But if you do get the tension with the hand behind the head it could be that the tension is in your ulna nerve.
Basically to mobilise it you recreate that tension then add and release it by moving the hand 15 reps 2 sets twice daily.
You may find it eases off immediately or it may take a while or it may move a little bit.
Keep checking in for other information...and good luck!

Don't know if this is the place to post but.

My Masseuse says that I have quite an externally rotated right hip.  When I walk my foot turns outward.  She says that I should try and keep the foot pointing forward as I walk ?

I find I get a recurring ache in my right hip after lots of walking, deadlifting and tend to shift my weight to my left leg if standing. I have quite an active job in a pub where I'm standing and walking constantly for six hours at a time.  I recently changed my shoes for a pair of Crocs and that has seemed to help a lot but the problem has started to come back.

Are there any exercises to stengthen the internal rotators or stretching external rotators ?

I used to practice Taekwondo and found that my right side kick was never as powerful as my left and the foot and hip were in the wrong position (difficulty getting the 'footsword' right)

I also have quite tight hams (though good flexibility), very sore near the origin (torn/strained them both in the past).  The muscles in my left lower trap area are also very tight and there are regular trigger points there.

Thanks

Jazz

HI Jazz
Yes you are in the right place for this kind of post.
If I can stress, as always, this is not as good as screening in person but my job here is to do all I can to explain the principles of Intrinsic Biomechanics and how they play a vital part in everyones exercise programme.
For those preparing or already training for their sport, whether a beginner or elite level this programme is  essential and the principles are really very simple.
 
What you are describing is a very common issue that can potentially be very easy to help with some easy muscle release techniques. An understandably common response to tension in the body is to stretch the 'tight' area or to strenghten the opposite direction of the pull. Both of these actions can in fact make the issue worse.
Let me explain:
Often muscles can go into a sub-clinical spasm or become over active. This is not the kind of spasm that you might actually feel as pain or that we usually understand. It is a condition that builds up over time for some reason without being aware of it (it can be that the muscle is trying to protect a vulnerable joint for some reason like excessive range, being sedentary or being on your feet for a longtime- for example) and it creates a knot in the muscle that is just like a rope with a knot in the middle of it. Imagine pulling on either end of that rope (as you would if you tried to stretch the muscle) it will just tighten because it is trying to stop the movement for a reason. So we need to re educate the muscle with a muscle release technique.
We call it the 20/20 technique because during the research that we did we found that a 20% muscle contraction held for 20 seconds gave the best results in releasing these over active muscles.
 
From the descripton you gave it could be that your piriformis muscle is over active causing the pelvis to twist. This could also be the reason for your thoracic discomfort. So a great way to release this muscle is to sit back in a chair and cross your ankle over the opposite knee. (Make sure your ankle joint is clear of the knee so as not to stress the joint).
Place your hand onto the inside of the top knee. Now with ONLY 20% of your maximum muscle contraction lift your knee into your hand in an isometric muscle contraction. So there is no actual movement because your hand will stop it. At the same time think about pressing the top ankle down into the knee.
So what are we doing here? 'It doesnt 'feel' like much' is what we often hear. Well you are basically creating a very subtle stimulation into the dysfunctional muscle. That subtle muscle engagement will remind the body how to allow that muscle to relax, re-educating the neuro muscular patterns that have become faulty.
You should try this 4 times in a set and if possible at least 4 times daily, definitely before you do any exercise, and make sure you put the leg donw in between each rep. Before you try this take a look at how high your knee sits away form the floor once it is crossed over the opposite leg and do this on both sides to compare symmetry. Once you have done this a few times re-check that height and you should see that your knee begins to drop slightly closer to the floor if this is the issue. Do this exercise on both sides and you will know if you have a pelvic dsyfunction if you compare sides and if on one side the knee sits higher than the other you definitely have asymmetry.
 
Please understand this is just one exercise amongst many and so if there is no result from this there are other things to try.
Keep me informed as to how you get on with it. The results can take up to 6 weeks or can even happen in just a couple of days.
Good luck!
:)

Thanks Rach : )

Is this when sitting in the chair or sitting on the floor ?  Same position as the test  ?

I'm guessing the exercise retrains the internal rotators and other muscles that oppose the hip rotation / pelvis rotation ?  So if the pelvis rotates too much to my right then my upper body will have to rotate to my left to keep in alignment.  So my upper back muscles (my left side) are contracting harder to keep everything in alignment.  Or something like that.

Sorry Jazz,
Sitting in a chair for both assessing and exercise.
What this exercise does specifically is release the piriformis which, once passed 90 degrees of flexion, becomes in internal rotator. The release techniques can be done in a variety of positions but it is most efficient when the muscle is in it longest position and so the seated '4 sign' exercise is the one that gets the best results.
 
There is a direct Biomechanical link between the hip and the trunk and so if your pelvis is twisted and not moving as it should then the body will compensate elsewhere for this lack of movement, like your left upper back.
So some spinal mobilisation stuff may well help a little too.
Try shoulder rolls lying on the floor. Knees bent, feet hip width apart, arms straight above chest, fingers laced together. Keeping hips still and level rotate whole of upper body from left to right, keeping nose level with thumbs. Keep arms locked straight and this will mobilise your thoracics.

Hi Rach,
 
just wanted to update you on my progress... If you remember I had lots of problems with my hands.. typical RSI symptoms.. nerve tingling and numbness weak hands in morning etc.. Well... I followed the nerve mobilisation exercises and also bought some Ironman resistance bands for hands and with a combination of both I have seen a massive improvement in my hands.. This morning I had virtually full strength (unheard of for months) and the last week very very little problems with tingling etc.. and no problems with weight training.  So thanks for the help..  Do I need to keep up the nerve mobilisation? Cheers, Nev.  (Please note NHS offered me an operation with limited success for this!)

Hey Nev
Thats great news! Thank you for keeping me up to date with your progress too.
Now please understand that is by no means necessarily the end of all of your Biomechanical issues as I am sure you can appreciate. The body and all of its structures are very much linked as well as life itself being very asymmetrical!!
But if you keep an eye on my Q&A I am adding information to it all of the time that may also be helpful. If you have anything specific please ask away and in the meantime keep using those nerve mobilisation exercises, no more than twice daily and you can build up to 30 reps x 3 sets.
How great to improve without the surgery!
Well done mate :))

hey rach

Wonder if you could help me, im not sure if this is to do with biomechanics or not, im gettin elbow/lower tricep pain i think it may be tendons, how would i go about strething the tendon before a workout?

thanks

HI there
If you are getting pain then it is probably more than just weak tendons. If you haven't already, take a look back over this thread and you wil see some nerve mobilisation techniques that can help with this type of thing. You can screen yourself and then do some real simple exercises to help it. I have already had some great feedback from one MT member about them.
If you need any more advice though please do come back to me and let me know how you get on.
:)

hey
If you have pain then it is unlikely to just be weak tendons. If you haven't already, take a look back over this thread and you will find some really easy techniques to screen your nerves and mobilise them for this kind of thing.
It is very common and one MT member has had great success with the Median nerve release technique.
So please do let me know how you get on and if you have any more questions about the body and its mechanics please get back in touch!

hey

Thanks for the reply, i tried the median nerve technique i felt a little tightness althought i may be doing it wrong, have you got a link from the internet that demonstartes with pictures?
