Stretching reduces spasticity. Yeah, no.

OK class, here's your quiz:

1. Stretching decreases spasticity T/F

2. Stretching increases the length of spastic muscles T/F

3. Stretching reduces the chance of contracture (muscle stuck at a shortened length) T/F

4. Stretch helps make joints more mobile T/F

First of all, why stretching is good: 

Stretch is good for joints. Every time we move, joints are "lubricated." That is, joints require movement in order for the fluid in the joint (synovial fluid) to be properly distributed. Stroke survivors, because they are typically weak on one side, don't get the joints on the "bad" side to move enough. How much is enough? Look at it this way, on the "good" side your joints, all of them, will be moved through their entire arc of movement (called range of motion) dozens if not hundreds of times per day. How many times are your "bad" side joints moved? Because they have trouble moving, it is wise to move them either with the "good" side doing the work, or a caregiver doing the work. This is called passive ranging.

But while stretching may be good for joints, the affect of stretch on muscles and other soft tissue (ligaments, blood vessels, fat, etc.) is, so far as the science says, negligible. So the answer to your quiz is F, F, F, and F.

I know this is hard to believe. And it is counter to what some therapists think. But it is confusing. There is an immediate effect of stretch on spasticity, everyone knows that. But this is one of the many reasons stroke is so devious; what is true now may not be true 5 minutes from now.

This is a frustration for many clinicians. You observe something is true (i.e. spasticity wanes with stretch) only to find that with the next big movement by the survivor, spasticity comes right back.

Pot Decreases Spasticity.

If you want to reduce spastcicity, move to Colorado. Pot (or the active ingredients in pot) can potentially reduce spasticity. This includes every pathology in which spasticity is a sequelae, like...

stroke

multiple sclerosis

spinal cord injury 

dystonia (see reference section)

But wait there's more! It turns out that pot make have a benefit for much of what ails survivors from arterial disease to seizures (10% of survivors experience a seizures). So why has your MD not talked to you about Mary Jane as a possible treatment for, well, anything? Simple. It is  the burning weed with its roots in hell duh!

And its dangerous. Very Very Dangerous.

The problem with Botox

When it comes to spasticity reduction, Botox is the 600 pound gorilla. It is the Oracle. If Oz was the world of spasticity, Botox would be its Wizard. Allergan, the company that makes Botox dictates the conversation. Why? Cold hard cash. Allergan made significantly more than $1 billion in the third quarter of 2012 alone.
 
Keep in mind that Allergan makes other drugs besides Botox. And spasticity isnt the main reason Botox makes 'em money.  The main reason Botox makes money is because of its wrinkle reduction qualities. Bottom line: they have plenty of cash. And they use that cash to influence opinion. This is inevitable, but also unfortunate. The influence that can be bought chips away at a discussion of other possibilities.

What are the other possibilities?

Phenol blocks. In the book "Spasticity: Diagnosis and Management" phenol blocks are called: a "Dying Art" That Merits Revival.
 

Why does it merit revival? Phenol blocks do pretty much the same thing as Botox for spasticity. But it costs less. Much, much less. This is something you should discuss with your doctor. It may be true that Botox is the best option. But it may save you some money to ask about phenol blocks. How much money is saved?

For muscles in the arm/hand, this is one estimate...
Botox: $1014.84
Phenol: $7.85

Another thing about Botox. For a long time the suggestion by Allergan was that Botox should be administered, and that's it. Botox provided a "vacation" from spasticity. They are in the business of selling drugs, not in the business of reduction of spasticity in any sort of permanent way. Remember, Botox does not cure spasticity. Phenol blocks are the same. All Botox and phenol blocks do is provide a window of opportunity to to regain executive (brain) control over spastic muscles. A classic example is of somebody that cannot open their hand. Spasticity in the muscles to close the hand is so strong that they can't open the hand. Botox or a phenol block is used to weaken the muscles that close the hand. This "unmasks" the movement that was always there: Hand opening. Now the hand can open because it's not fighting the spastic muscles that are trying to close the hand. But instead of treating this as a vacation, the person works hard to get the brain re-involved in all the muscles. (Allergan has changed its tune about this with prompting by me and others. They now say: administer Botox and then get therapy.)

During the "vacation" block provide hard work can help permanently reduce spasticity. 

Otherwise, it's just a vacation.
