The Effects of Blood Flow Restriction-based Abdominal draw-in Maneuver on Activation of Abdominal Core Muscles in Patients With Non-specific Low Back Pain
A study testing blood flow restriction in people with Non-specific Low Back Pain, run by China Medical University Hospital at 1 site in Taiwan.
Trial summary
The transverse abdominis (TrA) is the deepest muscle layer of lateral and anterior abdominal wall and also known as a significant component of core stability. Abdominal draw-in maneuver (ADIM) is the main for the strengthening of the deep muscle, however, sufficient activation of TrA by ADIM is limited. Read more about this study

About this study
The transverse abdominis (TrA) is the deepest muscle layer of lateral and anterior abdominal wall and also known as a significant component of core stability. Abdominal draw-in maneuver (ADIM) is the main for the strengthening of the deep muscle, however, sufficient activation of TrA by ADIM is limited. Blood flow restriction (BFR) training is a technique combined with low intensity exercise that produces similar results to high intensity training. Therefore, the purpose of this study is to explore whether BFR-assisted ADIM can become a new auxiliary way to train TrA, and whether it can better activate their TrA in patients with low back pain. Low back pain (LBP) is a major health problem with huge economic and social costs. Core muscle weakness is a risk factor for LBP. Past studies have also pointed out that the biggest cause affecting the quality of life and activities of modern people is lower back pain. In modern life, low back pain can be said to be a very common disease. According to past research, there is a 50% to 70% chance that people may have lower back pain in their lifetime, and non-specific low back pain accounts for the majority (90%), the reason why the influence of non-specific low back pain is so great is not only physically but also psychologically. When people perform many functions of daily life, people need the help of the waist. But once the wrong way of effort or posture will lead to more pressure on the spine, leading to greater pain, a strong sense of discomfort will haunt them for a long time. Therefore, the activation and control of TrA is very important because of the relationship between the lateral direction of TrA, so when TrA contracts, it will result in a decrease in waist circumference, an increase in thoracolumbar fascia tension and an increase in intra-abdominal pressure, so it is regarded as the most important stable muscle in the core.In addition, TrA is a special presence in the core muscle group, it can independently contract and like the presence of waist protection to stabilize our spine, but because it is located in the deepest layer, coupled with less muscle activity, it is difficult to effectively activate correctly, so if TrA is not activated or contracted correctly, it may cause non-specific lower back pain.
Read the detailed description
In this study, 20 healthy people and 20 patients with lower back pain were recruited and divided into healthy group, experimental group (patients with lower back pain) and sham experimental group (patients with lower back pain). The subjects in the experimental group and the healthy group were tied under the ribs with a pulse band (14 cm wide and 84 cm long) to block at least 60% of the blood flow and do abdominal exercise. In the sham experimental group, the ventral compression band was fastened but the abdominal contraction exercise was performed without inflation. Each subject exercised for 20 minutes twice a week for six weeks. At the first, third and sixth week, ultrasound (Ultrasound, USD) was used to evaluate the muscle thickness and muscle activation of external oblique muscle, internal oblique muscle and transverse muscle (core muscle group). This study expects that blood blocking training can increase the degree of activation, muscle strength and hypertrophy of transverse abdominal muscle in patients with lower back pain, and can provide a new auxiliary method to improve the predicament that it is difficult to activate transverse abdominal muscle correctly.

What is being measured
The primary outcome is the main question the study is designed to answer.
Muscle thickness
In this study, abdominal muscles were evaluated by Brightness-mode, 5M-Hz, Linear).
The thickness of meat during abdominal muscle relaxation and during draw-in. The probing position is located at the lowest end of the rib and in the middle of the iliac spine.
At the midpoint of the axillary line. Put an ultrasonic image of the abdominal muscle in the abdominal muscle and vomit in ADIM.
At the end of the day, we take an image. Then calculate the muscle thickness. The calculation standard is from the tail and abdomen of TrA The fascia joint tip is three centimeters inward, and the muscle thickness of transvers abdominal, internal oblique and external oblique muscle is calculated from bottom to top, and Total muscle thickness, measured in centimeters (cm).
Measured: The experiment was conducted for a total of five weeks.After the first ultrasonic image estimation and the fourth week, all the assessments are carried out again, and then tracked down in the fifth week. Estimate.
