Effects of Abdominal Muscle Activation Training, Using Pressure Biofeedback in Comparison With Surface Electromyography

"PBF assisted abdominal muscle activation training (30 min, 3x /week /4 weeks) Progressive Muscle Relaxation for 5 min Pressure biofeedback assisted abdominal muscle activation training. Frequency: 25 min; 10 sec hold, 15 sec relax, 10 reps Progression criteria in training: Maintaining 3 - 5 mmHg pressure on PBF dial while performing abdominal muscle activation.~Exercises for Group For biofeedback assisted abdominal muscle activation training these exercises will be performed:~1. Supine abdominal muscle activation (45° Hip knee flexion)~2. Both hip and knee 90° flexion~3. One side hip and knee 90° flexion with other fully extended~4. One side hip and knee 90° flexion with other fully extended + heel 12 cm raised~5. Both legs fully extended with heel 12 cm raised~6. Partial curl ups~7. Prone lying abdominal muscle activation~8. Prone leg raises~9. Prone upper back extension simple~10. Prone reciprocal UE/LE exercises"
