Details and patient eligibility

About

This study aimed to reveal the role of inspiratory muscles exercise using Inspiratory Muscle Trainer (IMT), which is a form of weight training. The pre- and post study of this experiment were conducted in chronic obstructive pulmonary disease (COPD) outpatient clinic during the period of September 2017 until April 2018. Patients were recruited by consecutive sampling. Inclusion criteria were stable COPD patient with The Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria A-D, who has never received prior exercise for pulmonary rehabilitation, and willing to participate in the study. The exclusion criteria included any problem with extremities and cardiovascular disease. Patients underwent an interview about their medical history, tested spirometry using CareFusion®, and the inspiratory muscle strength was assessed using Micro RPM CareFusion®. The St George Respiratory Questionnaire (SGRQ) was used to assess the health status and the 6-Minute Walking Test (6MWT) was conducted to assess functional capacity. Subject exercised using inspiratory muscle trainer (Philips Respironic®) for eight weeks.

Full description

Intervention is given using Inspiratory Muscle Trainer Philips Respironic®. Impact on inspiratory muscles strength, health status, and functional capacity are observed. Muscle strength is evaluated using Micro RPM (Respiratory Pressure Meter) Carefusion®. Health status is evaluated using St. George's Respiratory Questionnaire (SGRQ), while functional capacity is evaluated by the 6-Minute Walk Test (6MWT).

Patients were recruited by consecutive sampling. This study was granted ethical approval from the Institutional Review Board (IRB) of the Faculty of Medicine Universitas Indonesia Subjects exercised using inspiratory muscle trainer (Philips Respironic®) for 8 weeks. Inspiratory muscles strength (Maximal Inspiratory Pressure, MIP) and 6MWT were done at the beginning for basic data and were re-evaluated during the second, fourth, sixth and eighth week (last week). Questionnaire (SGRQ) was done at the initial and end of research.

Training dose with IMT was determined by inspiratory muscle strength result and adjusted in every evaluation visit. The subject was expected to do exercise twice daily for 15 minutes each session with 30-70% intensity from determined MIP score. Exercise is monitored and noted in a logbook.
