**9. Conclusion**

Chest mobilization techqniues are very useful in clinical practice for improving lung ventilation and gas exchange. They also can be applied in various cases, for example, chronic obstructive pulmonary disease (COPD), pneumonia, chronic illness from stroke, spinal injury, prolonged use of a ventilator, etc. These techniques can be applied with others such as breathing exercise, cough training, or exercise in regular pulmonary rehabilitation. Before and after intervention, assessments of observations, palpation or chest expansion measurement,, including X-ray recheck and lung function test, are very important for confirmation of clinical improvement with a single case research design. Improvement of ventilation and gas exchange is very important in gaining health status or quality of life in ICU, or sub-acute or chronic stages. Efficiency of aerobic capacity directs the function and physical performance in daily life. However, this chapter is an example of interesting theory that needs more study to confirm its results. It is hoped that there will be more reports or wider application of chest mobilization in hospitals and communities for improving health status and pulmonary rehabilitation.
