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
