Effects of Respiratory Muscle Training on Pulmonary Function

Effects of Respiratory Muscle Training on Pulmonary Function of Patients With Chronic Neck Pain

The study was conducted to determine the effects of respiratory muscle training on pulmonary function and musculoskeletal parameters in patients with chronic neck pain. It included 43 patients, 20-40 years old males and females having non-specific chronic neck pain for more than three months and with low maximum voluntary ventilation (MVV) values were included. Control group (n=21) received conventional physiotherapy with diaphragmatic breathing exercises and experimental group (n=23) received conventional physiotherapy with specially designed respiratory exercise protocol. It concluded that RMT in addition to conventional physiotherapy is effective to improve musculoskeletal and pulmonary parameters in CNP patients.

Study Overview

• Status: Completed
• Conditions: Chronic Neck Pain
• Intervention / Treatment: Other: Neck stretching exercises

Detailed Description

To determine the effects of respiratory muscle training on pulmonary function and musculoskeletal parameters in patients with chronic neck pain.

Study design: A randomized controlled trial Place and Duration of Study: Riphah Rehabilitation and Research Center in Railway General Hospital and Benazir Bhutto Hospital, Rawalpindi from January 2019 to July 2019.

Methodology: 43 patients, 20-40 years old males and females having non-specific chronic neck pain for more than three months and with low maximum voluntary ventilation (MVV) values were included. Control group (n=21) received conventional physiotherapy with diaphragmatic breathing exercises and experimental group (n=23) received conventional physiotherapy with specially designed respiratory exercise protocol. They were assessed prior to, at 2nd week and after 4 weeks of treatment.

Number of Arms

2

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Respiratory muscle endurance training; Volume oriented incentive spirometer improves respiratory muscle endurance and chest expansion.	Other: Neck stretching exercises; Neck stretching exercises towards lateral flexion, ipsilateral flexion and rotation and towards flexion each for 30 sec and repeated 2-3 times
Active Comparator: Diaphragmatic breathing exercises; Improvement in diaphragm contraction, chest wall symmetry and reduce activity of accessory muscle due to diaphragmatic breathing technique causes respiratory muscle endurance to improve.	Other: Neck stretching exercises; Neck stretching exercises towards lateral flexion, ipsilateral flexion and rotation and towards flexion each for 30 sec and repeated 2-3 times
