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.

Conditions

Respiratory System Abnormalities

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Manual Diaphragm Release

received 3sessions/ week for 12 consecutive weeks.

Group Type: EXPERIMENTAL

Manual Diaphragm Release

Intervention Type: OTHER

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.

control group

received 3sessions/ week for 12 consecutive weeks.

Group Type: EXPERIMENTAL

control group

Intervention Type: OTHER

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:
