The improvement of muscle strength and decrease in rectus
separation in group (A) could be explained via Warren et al.,
[20] and Ivancic et al., [21] in which they reported that the
abdominal belt improves the strength of abdomen, thereby
increases the intra abdominal pressure that contributes to
mechanical spine stability through co activation of trunk
flexors and extensors musculature. As the abdominals
contract, intra abdominal pressure increases and converts the
abdomen into a rigid cylinder that greatly increases the
stability of the spine, improves abdominal strength and
decreases abdominal separation so the abdominal belt play an
important role in the stabilization of the lumbar region during
lifting, produces significant improvement of the lifting ability
with decreased muscular fatigue and strain and improves the
ability to perform the ADL activities.
The abdominal binder achieved immediate waist reduction
as the soft fleshy tissue compressed, squeezed and
redistributed above and below the waistline. Also, it holds the
abdominal muscles in at the right tension and prevents them
from becoming flaccid and expanding. The binder has to apply
the right pressure without strangulating and at the same time
exerting a necessary pressure on the abdominal muscles
