Muscle Stiffness – When It Hurts to Move too Quickly

Muscle stiffness is a symptom seen when muscles cannot move quickly without getting pain and/or spasm.

Sufferers have to move slowly. They quickly work out that after the muscle has not been used for some time – e.g., on rising from sleep, or from having sat in one position for some time – then their first movement has to be particularly slow, gentle and tentative. Moving too quickly brings about acute pain and possibly spasm.

Usually it’s the back, neck and proximal muscles of the shoulder and hips which are affected.

I think that the reason for this arises from the fact that evolution never meant human beings to walk on two legs. However, we have inherited the muscle structure of creatures walking around on four legs. This means that these muscles are working at a huge mechanical disadvantage and therefore great strains are placed on them which evolution never really intended.

Happily they have developed sufficiently well to get us past child bearing, which is all that evolution cares about. So it is no surprise that stiff muscles tend to be associated with old age.

John McLaren Howard also comments that quite a few muscle stiffness sufferers seem to escape the tendency to spasm and rarely report cramp. This group seem to have high intracellular calcium in the presence of adequate magnesium. Those who suffer spasm and cramp when trying to free up muscle stiffness often have low magnesium and/or poor thiamine (B1) status. [Dr. McLaren-Howard, a pioneer in nutritional and environmental medicine, co-founded the Biolab Medical Unit – a London-based lab specialized in development & provision of tests to assess bodily levels and imbalances of vitamins, minerals, and other nutrients.]

Muscle stiffness is surprisingly common – most people just adapt if the symptoms are not too severe. However, even gentle massage will make enough difference for them to realize that there is a problem. Heavy massage generally makes it worse!

Muscle spasm can occur in people who have no signs at all of general or even specific muscle stiffness.


So the first question to ask is: What are the possible mechanisms that bring about muscle stiffness and spasm?

The answer is I don’t really know, but thanks to John McLaren Howard… I now have some ideas which seem to accord very nicely with the clinical practice and bio-chemical findings.

The first point is that for muscles to relax they require magnesium, and for muscles to contract they require calcium. Any imbalance of this, i.e., too much calcium or too little magnesium very much increases the tendency to spasm and contraction. Modern diets are low in magnesium and high in calcium and this will increase the tendency therefore to spasm.

Secondly, other dietary indiscretions will also raise intercellular calcium levels. Calcium is held inside cells via a binding protein, and this is stimulated by cyclic AMP and insulin. The two dietary problems which induce these enzymes are caffeine and carbohydrates, respectively. Therefore a Western diet will tend to predispose toward muscle stiffness.

Thirdly we have the issue of allergic muscles. [See Dr. Myhill’s article “Allergic Muscles,” proposing that torn or bruised muscles may come in contact with food antigens in the blood, and become sensitized.]

Fourthly, having established a tendency to muscle spasm and pain, we get a learned response. The brain anticipates that the muscle will go into spasm if moved too quickly, and therefore all movements are generally slowed down to prevent this from happening.

It may well be that therapies known to be effective for stiff muscles such as Pilates, Bowen technique, massage and other such manipulations are re-educating the brain into realizing that it is now “safe” to move freely. However, they will be much more effective if the underlying physical causes are also addressed.

Finally there is clearly a neuro-psychological element. The brain is also responsible for muscle tone, and neurological problems such as Parkinson’s disease will result in muscle stiffness or even spasticity. Psychological stress will also tend to increase muscle tension and worsen an underlying tendency. Diazepam (Valium) is one of the most useful muscle relaxants.

Eat a low allergen, low glycemic index, low caffeine diet. See “Stone Age Diet – A Diet We All Should follow.”

Take the right balance of calcium and magnesium in the diet, firstly by eating a Stone Age Diet and secondly by taking “Nutritional Supplements.”

Correct mitochondrial function. 40% of resting energy does nothing but kick calcium out of cells and drag magnesium into cells. Therefore should mitochondria start to fail, then one of the first things to go is muscle tone, perhaps because the calcium is building up in cells and magnesium is leaking out. We know that the ageing process results from mitochondrial failure.

(See “CFS – the Central Cause: Mitochondrial Failure.” This is a large subject, with links to “Detoxification” and

Antioxidant function. If a stiff muscle is suddenly stretched, then this will physically tear muscle fibers. Healing and repair is carried out by the immune system, which does this via a process of inflammation. Whilst this is a necessary part of healing and repair, too much inflammation causes too many free radicals which then cause damage in their own right.

Therefore it is very important to have good antioxidant status in order to limit damage created by inflammation – [see “Antioxidants – What They are and Why We Need Them.”]

With age there is a tendency towards inflammation. Vitamin D (yippee – lots of sunshine) and essential fatty acids are natural anti-inflammatories. Some herbs such as Devil’s Claw and curcumin have anti-inflammatory properties. Poor adrenal function with low levels of DHEA can increase a tendency to inflammation – see “Adrenal Hormones” and “DHEA – an Important Adrenal Hormone.”

Be careful with aspirin and other such non-steroidal anti-inflammatories (NSAIs) which cause gut problems and are pain killers – pain is Nature’s way of telling you to go gently with a muscle, and one does not want to damage muscle if it should be rested.


John McLaren Howard again comes to the rescue here with a fascinating idea which makes interesting links between the physical and the biochemical body! The idea here is that if a muscle is gently squashed (massaged) it responds with an “equal and opposite” pressure. Because massage does not involve active contraction of the muscle, calcium is not involved. But when the muscle relaxes, magnesium is involved, so magnesium floods into the cell and pushes calcium out.

Effectively, gentle massage pumps magnesium into cells and calcium out. Perhaps this is why one feels gorgeously relaxed after gentle massage?

• However, the massage cannot be done by self, because the initiation of that would involve calcium fluxing into cells. It has to be done by another person, (or perhaps machine?).

• Furthermore it has to be done very gently – harsher massage would involve calcium fluxing in again and be counter-productive.

People with muscle stiffness can benefit greatly from moving all joints through their full range of movement before weight bearing (i.e., before even getting out of bed). This should be done slowly and gently and there must not be any undue stretching at the end of each movement as this will initiate a calcium-into-cells action.

What one is doing is showing the muscle groups what is expected of them without invoking additional contraction – i.e., without encouraging calcium input into muscle cells.

One thought on “Muscle Stiffness – When It Hurts to Move too Quickly”

  1. Svette_Palme says:

    I am the type that gets muscle spasms when I move or stretch my muscles, and I find that moving slowly will help me avoid a lot of pain and cramping, so I probably fit into the “low magnesium group”

    “if I have low magnesium and resting brings magnesium INTO cells, that explains my need for rest”
