The short-term effects of of stabilization Exercise on the stability index of Biodex system, abdominal and back muscle electromyography (EMG) and lumbar curvature in men with non-specific low back pain (NS.CLBP)
This study investigated the effects of short-term training "drawing in or Abdominal Hallowing (AH)" and Abdominal Bracing (AB) techniques on the stability index of Biodex, abdominal and lumbar EMG muscle activity and lumbar curvature in men with Non–Specific Chronic Low Back Pain (NS-CLBP). Twenty male patients with NS–CLBP (as intervention group) and 10 matched patients (as control group) were enrolled. Participants were trained in a single day training session before the test session to become familiar with the equipment and exercises used in the study. The patients in the intervention group were randomly assigned in a cross-over manner into one of the above-mentioned exercises with a week washout period. Before and immediately after exercise, muscle EMG activity, lumbar curvature, and stability index by Biodex system were measured.

Description
First Intervention: Abdominal Hollowing exercise
"Drawing in" or "Abdominal Hollowing" training: The subject was placed in crock lying position and was taught special and isolate contraction of Transversus Abdominis muscle based on Richardson concepts. Training will continue until the patient was quite remembering the correct contraction. The subject was instructed to pull him navel in (toward spinal column) and up (less than 10 percent maximum voluntary contraction MVC). When ideal contraction of Transversus Abdominus was obtained (best activation with minimal other muscle activation), was asked them to hold contraction with breathing and Imprisonment not their breath. Pressure BoiFeedback Unit was used for control of muscle contraction. 3 set each one with10 repetitions while 2 minutes as a rest period between each set and keeping contraction of muscle for 10 seconds was the ultimate goal.
Time of training, depends on correct learning of Abdominal Hallowing and was different between patients.

Description
Second intervention: "Abdominal Bracing exercise
"Co-contraction" or "Abdominal Bracing training. ّFirst, a natural waist position (slight lordosis) was investigated ,then subject must contract all muscles as 360º around the trunk(area of lumbar spine), such as someone pressure to his waist but he can resist while he had normal breathing , at beginning of this maneuvers ,therapist would give touch feedback with her hands to the patient and after learning, patients would do it himself Pressure Bio Feedback Unit Was used to control of correct contraction of abdominal wall muscle. Patient must reach a stage that can do this maneuvers simultaneously with normal breathing and maintain this state about 10 seconds. This exercise in supine crook lying mode is done. Llike the first intervention, achieving to 3 set each one with10 repetitions while 2 minutes as a rest period between each set and keeping contraction of muscle for 10 seconds was the ultimate goal.

Description
Control group:
For subjects of this group was not performed any intervention and the mean duration of time equivalent to the intervention training group, were given to them instead of intervention period between data recording because for the real effects of the intervention in the treatment group is determined .
