people with lower back pain weighed more than their uninjured peers, a factor that significantly increased pressure on the spine

1. Back Pain Worsens When One Avoids Using the
Back
A team of researchers has identified a catch-22 of lower back
pain.
Those with lower back injuries can worsen their pain by avoiding using hurt muscles.
Other muscles, including those in the abdomen or on the sides of the torso, contort to
compensate, leading to greater pressure on the spine and damaging discs.
Researchers have long suspected that patients guard their trunk muscles but this study has shown
for the first time how this results in increases in spine loading that can lead to secondary back
injuries.
The investigators then measured the electrical activity of participants' muscles and compared
pressure on the spine, known as spine loading, and the side-to-side force on the spine, know as
lateral shear.
Adults with lower back injuries used more muscles in the back when lifting, creating greater
pressure on the spine. Injured patients experienced about 26% greater spine compression, a 75%
increase in lateral shear, and used significantly more muscle activity for 10 muscles than non-
injured adults.
Additionally, people with lower back pain weighed more than their uninjured peers, a factor that
significantly increased pressure on the spine.
Excessive body weight, or a protruding stomach, is like always holding a box in front of you.
One must counterbalance the weight with more activity in the back muscles that aren't as far
from the spine. It is like a seesaw where the back muscles are not as far from the fulcrum as the
weight of the belly.
The results of the study underscore the need for people with lower back pain to trim down, and
suggest that physical therapy for certain types of back injuries aim to teach patients how to use
their back muscles appropriately, the authors note. Typically, physical therapy focuses on
strengthening the trunk muscles.
