If
you've never had a serious back complaint you're fortunate, but you're
also in the distinct minority. It's estimated that 85 percent of the
population will endure some significant back problem during their
lifetime, and that's the general population. For the biker population,
given their demographic profile and nonsedentary pursuits, I'd suspect
that percentage to be somewhat higher, and among riders of hardtails, I'd
expect that percentage to jump up somewhere into the range of about 300
percent. That's a statistical impossibility, I realize, but I'm counting
multiple hump-busting injuries, one each for the three components of
hardtail OEM rear shock absorbers-the lumbar, sacrum and coccyx.
Another pertinent statistic in this regard is that only 10 percent of back
injuries are the result of obvious trauma like heavy lifting or falling
off a roof. The balance is attributed prosaically to prolonged bad
posture, and are, as such, preventable. In other words, quit slouching.
That's easier said than done, since slouching is pretty much what humans
do naturally and few people outside of finishing schools and service
academies have ever cultivated a proper postural discipline. If keeping
your back straight is not a habit ingrained in your psyche, you just don't
do it.
Telegram for Mr. Lumbar
While poor posture in any activity makes your backbone vulnerable, it's
particularly pronounced when riding a motorcycle. Slouching in the saddle
optimally positions the lower back for damage when you take the kind of
jolt a swingarm telegraphs from a pothole, or a hardtail telegraphs from
an expansion joint-or a picture of a pothole. So how do you go about
maintaining healthy posture? Good question. I'll bet you're slouching
right now… and now you're not, but only because I pointed it out. Therein
lies the rub and, as we shall see, the solution.
Lacking that ingrained awareness of your alignment, the natural
inclination is to strap on an appliance of some sort to keep your
vertebrae and discs shmushed into shape; some kind of elastic corset like
stock handlers wear at Wal-Mart, perhaps. And it must be acknowledged that
elastic body wraps are indeed effective-effective at making you look and
feel like a human sausage link. A sausage link, alas, with poor posture.
Interestingly, it was in fact Wal-Mart who funded the study by the
National Institute of Occupational Safety and Health that determined that
these rigs are worthless in preventing back injury. (You're slouching
again.)
Body talk
The Back-A-Line riding belt takes a different tack in approaching the
posture problem. It relies not upon strictly mechanical means to keep you
upright, but upon a phenomenon called "proprioceptivity"-the ability and
inclination of your body to respond to subconscious cues. Consisting of a
sturdy polyester belt into which is sewn a molded foam lumbar pad with a
channel to accommodate your spine, the Back-A-Line is worn snugly, but not
tightly. The intent is not to brace your back, but to suggest a healthy
position to it. The belt basically leaves your brain out of the
conversation, as it were, and talks directly to your lumbar, keeping up a
constant subliminal patter of correction and encouragement like your own
little spinal Pilates instructor: "Straighten up! Good! Stay aligned!
Beautiful! You go, vertebrae!" The shape and position of the belt teach by
example, and your spine responds. |
That's what the
promotional material from Back-A-Line told me anyway, and like you, my
initial response was: "Right. Sounds reasonable. Now if you'll help me
back up on the turnip truck I'll go and buy one." It sounded like so much
biomechanical voodoo, but reading on, I learned that Back-A-Line has the
documentation to substantiate their claims. The proof issued from the
Fourth Applied Ergonomics Conference held at Ohio's Miami University.
(What a swell convention that must be. I can't help but picture a hotel
bar full of nerds sitting bolt-upright on barstools attempting to hoist a
few without being repetitive about the motion.) Anyway, that august body
of body experts determined conclusively that the Back-A-Line improves
posture, and was the only product of its kind that actually does so. The
belt does talk, and the spine does listen. (You're slouching again.)
From theory to practice
Products like the Back-A-Line belt are not the easiest to actually
evaluate, as you can probably imagine, but I did devise what I considered
to be an adequate methodology. The test equipment consisted of a borrowed
Panzer DXF-C hardtail chopper, and the test track was the 20 or so miles
of back road between Nemo and Sturgis, South Dakota, a serpentined route
through the Black Hills that included a couple miles of washboard gravel
and an off-grade railroad crossing on the edge of town. A test dummy was
employed for the procedure, and I installed it by throwing a leg over the
saddle of the Panzer. The drill was simple from there on out. I'd wear the
Back-A-Line while riding the hardtail for a few days over that course and
then make a determination as to whether or not I was in pain, or could
feel my feet.
That's simple enough, and I would have considered my duty fulfilled with a
few passes over those final miles of wretched cheese grater gravel without
blowing out anything musculoskeletal. That would suffice for the
evaluation and be adequate foundation for saying nice things about the
product, and in point of fact I did make a number of laps without
squishing a disc or tweaking my slinky out of whack, and that should have
been the happy summation of the trial. I hadn't intended to get any more
thorough or scientific than that, and certainly hadn't intended to serve
as my own control group…
But that's what happened
See, on the last run into town to drop the DXF-C back off at Panzer, I
didn't wear the Back-A-Line. It was, I reasoned, a quick final hop over a
now-familiar back road and stretch of gravel. It was a hot day and I
didn't want to be encumbered with the belt in town while wandering around
shooting photos. So off I rode, getting nearly all the way into town
without incident. I knew by rote now the smooth tracks through the
washboard, and rode along smartly without giving any thought to the
alignment of my spine. I also didn't give any thought to that railroad
crossing until I hit it slouching in my saddle. Mother McCree...
A month later I was still experiencing painful spasms from that episode,
but I took some comfort in a job well done. I had scientifically
demonstrated the difference wearing the Back-A-Line belt makes when riding
a hardtail over an abrupt railroad track, and it's not a lesson I'll soon
forget. As a matter of fact, I'm wearing the belt as I'm writing this. I'm
training my posture. And you're still slouching, aren't you?
