Repeated slow stretching synchronized with eyes closed and deep and slow breathing performed at least four times reduces neck pain and tension while promoting relaxation within a short period.
Slow deep breathing added to other interventions reduces disability in adults with spinal pain.
Diaphragmatic breathing exercise with visual biofeedback significantly increased forced expiratory volume in 1 second, functional vital capacity, and maximum voluntary ventilation in incomplete cervical spinal cord injury patients immediately after intervention.
Slow-paced breathing after physical activity reduced the difference in cardiac reactivity (measured by interbeat intervals) to negative versus neutral emotional images compared to control breathing.
Manual diaphragm relaxation combined with diaphragmatic breathing exercises improves chest expansion in children with diplegic cerebral palsy after 8 weeks of intervention.
