Here’s some personal follow-up research on ‘Foam Rolling’:
After my initial experiment with a home-made foam roller, I found that in use the drainpipe version tended to squash elliptically. So I got a 30cm length of stronger 4cm waste pipe and wrapped it in four layers of foam ex-yoga mat glued together using silicon rubber sealant. This gave me a roller 7.5cm in diameter.

Finding a suitable technique for ‘Foam Rolling’ is not easy – particularly for a partially seized-up bloke like me! I found that for my neck and upper back, I have to lower myself very carefully on to the roller (on the floor) and, with knees bent, roll back and forth using my legs to provide the movement. For my lower back I have to be very careful because I have a displaced vertebra. This involves my taking some of the weight of my body on my elbows and using elbows and legs to provide the back and forth movement. An important consideration (for me, anyway) is that upper body clothing such as a tee-shirt becomes wrapped around the roller, so, as I don’t have any tight-fitting Lycra or Spandex singlets (I could never be a ‘mamil’ – middle-aged-man-in-Lycra), I have to engage in this activity bare-backed.
Yes, it’s painful – on my lower back when the roller passes over the displaced vertebra it can be excruciating. But it is becoming easier with each session of ‘Foam Rolling’.
Is it safe? I have no idea! I could see that for some people it might be a very bad thing to attempt – there is quite a perceivable risk that the positioning of one’s body and the force applied to the back and neck could cause severe pain or injury.
Just to satisfy my own personal curiosity I did a few very rough calculations to see how much force I am applying to my back and neck when using my foam roller. This turns out to be about 1.13 kg/cm2.
To try to put this into some sort of context, The National Fibromyalgia Association, in 2005, gave guidance on how much pressure should be used by a trained examiner when carrying out the (no longer used?) Manual Tender Point Survey (MTPS) examination to produce pain in a Tender Point:
using just one thumb, a pressure of 1kg is first applied, rising to 4kg over a period of 4 seconds. This gives a loading of about 2kg/cm2. This is more than the loading exerted by my roller on me.
I don’t know if any of my data are technically correct or relevant – probably not. I haven’t taken into consideration the fact that using the roller produces a ‘rolling load’, or that for a lighter or heavier person the loading would be different. All I can say is, I’ve found some improvement in my back pain and flexibility.
