hello everyone dr. Lawrence woods from
this binary today we're going to ask the
question our chairs that recline
actually better for our backs most of us
at some point in our life has had
experienced some form of back pain and
the number of people who are
experiencing low back pain is increasing
at an exponential rate so you might ask
what is causing all this well there's
good reason to believe that this is the
chairs we use and also how we sit is the
major contributing factors to this
massive health pandemic if you like if
this is true is there anything we can do
right now if you're watching me right
now is there anything you could do right
now to avoid degenerative back pain well
here's the good news the good news is
most of our typical office chairs today
have a simple feature that just might
unlock the solution to better back
health contrary to common belief sitting
at a 90 degree angle meaning that your
legs and torso are making a right angle
is not nearly as optimal for your back
as we once thought
there have been decades of research
suggesting that a reclined position is
actually much better or put simply the
ability to lean back in your chair in
this video we're going to dive into
specific reasons on why this is the case
and why you should consider use an
incline on your chair the first study
we're going to look at they found that
it's actually better for the muscles in
your spine and this is research from an
article from JM PT and they found that
subjects would cease with backrest but
with an inclination of 110 to 130
degrees of course coupled with lumbar
support have the lowest pressure dis
pressures and the lowest
electromyography recordings from spinal
muscles and I hate using big words like
that shop Talk but what electromyography
or surface EMG is similar to like an EKG
or ECG it is just measuring the
electrical activity in around the
muscles or paraspinal muscles and
measures stress the muscles and stress
of the nerves so here we go so the
translation from this study is the
chairs with more of a recline are
associated with the reduction in muscle
activity and less nerve stress okay so
if you have a decrease in muscle
activity and a decrease in nerve stress
this means you will experience less
fatigue and tiredness how many of people
out there are tired right now when they
looked at the standing position which is
about 180 degrees researchers
a low level of muscle activity in the
back when they compared this to sitting
on chairs they saw a large reduction in
muscle activity in chairs that have an
incline anywhere between 110 and 130
degrees now saying this if you're gonna
add incline you're watching me right now
you want to incline you're gonna need to
reconfigure your workplace setup because
this new seating arrangement will lower
the position of your head and if you
want to learn more about the configuring
workplace please click on the annotation
on the upper right hand corner sitting
for long periods of time is widely
associated with all sorts of back pain
neck pain shoulder pain but more
specifically disk herniation and similar
to the results above the closer you get
to a standing angle the better it is for
the long-term health of the spine do you
ever remember back when you were a child
and you're sitting in the back class and
you're slacking you're slouching and
your teacher and yell at you to sit up
straight well it turns out that you are
right and sometimes our body tells us a
position that feels more comfortable is
actually better for our spines no matter
what the teacher tells us but one point
I really want to make if you're going to
use incline make sure you get a proper
lumbar support because it's imperative
that you use lumbar support when using
climbing so I hope you learned something
new in this video and something that you
can begin implementing in your daily
life right away it is vital for us to
get our posture right if we want to
maintain a healthy back and sitting the
right way maybe the most important place
to start to summarize the points may in
this video try to sit in an angle close
as possible to standing it is the most
biomechanically it's the most ideal
position for our bodies and it will
surely improve or prevent back pain hey
one last thing before you go if you're
interested in this type of video make
sure to check out our youtube channel
it's called the spine area we have a
variety of ice anything from sleep to
food to water - urgh anomic s-- also if
you enjoy the video please make sure you
give us a like ok because that really
helps us out I really appreciate this I
hope you have a great day thank you
