We can increase the number of electrodes if our unit has several outputs. This produces neuromuscular electro stimulation and covers more muscle tissue.
Rectus abdominis muscle
It extends from the pubic symphysis pubic crest inferiorly to the xiphisternum/xiphoid process and lower costal cartilages 5th, 6th and 7th superiorly.
It is primarily responsible for flexing the spine, particularly the section of lumbar spine. If we anchor the thorax, the rectus abdominis muscles move towards the thorax and if we anchor the pelvis the thorax moves towards the pelvis because of the action of the abdominal muscles.
Weakness in the abdominal muscles can lead to hyperlodosis, making movements that flex the spine very difficult.
The rectus abdominis is an important postural muscle, giving stability to strong arm and leg movements.
The rectus abdominis benefits tremendously from neuromuscular electro stimulation by proportioning stability and energy which is passed from the torso to the limbs.
If we have limited time, the rectus abdominis is the muscle that we should focus on first.
