Manual Diaphragm Release in Cleaning Laborer

Study Overview
=================
Brief Summary
-----------------
This study intended to examine the effect of manual diaphragm release on pulmonary function, chest wall mobility, and functional ability in female occupational cleaners with respiratory hazards.

Detailed Description
-----------------
Cleaning chores have been linked to exposure to various chemical agents that have the potential to cause harmful effects on both the respiratory system and cardiovascular markers, many cleaning products and disinfectants contain ingredients that can act as airway irritants. One of the physical therapy procedures that is used to manage chest disorders is manual diaphragm release which aims to lengthen the diaphragm musculature whereas encouraging better and more proficient contraction.

Official Title

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Manual Diaphragm Release<br>received 3sessions/ week for 12 consecutive weeks. | Other: Manual Diaphragm Release<br>* The participant was supine, with his or her limbs relaxed. With the therapist's forearms aligned toward the participant's shoulders, the therapist gradually increased the depth of contact inside the costal margin during the subsequent respiratory cycles.<br>* Other names: inspiratory resistance;|
| Experimental: control group<br>received 3sessions/ week for 12 consecutive weeks. | Other: control group<br>* Respiratory re-training was given to participants in control group in form of slow and deep diaphragmatic breathing, exhalation through the nose with pursed lips (the participants were trained to emphasis on expiratory pressure against pursed lips), Breathing control and breathing-hold exercises, and Relaxation techniques:<br>* Other names: Respiratory re-training;|
