Short term effects of MET programme in patients diagnosed with Chronic Obstructive Pulmonary Disease: a randomised controlled trial

Abstract

Background Muscle Energy Techniques have been reported to provide beneficial effects on range of movement in multiple musculoskeletal dysfunctions. Noting these physiological effects and clinical recommendations, the effects of METs are given importance through investigations on their input in managing COPD symptoms. The maintenance of such outcomes has though not been investigated. Therefore, the aim is to look into the short-term effects, 4-week post completion of the intervention, on pulmonary function, chest measurements, exercise tolerance and ADLs. Method This paper reports outcomes from a randomised controlled trial. 108 patients with COPD were recruited and assigned to 2 groups. The intervention group underwent a 4-week MET programme applied to the accessory muscles of respiration. The control group on the other hand continued with standard medical treatment. Outcome measures were assessed at baseline, at the 4th week time point on completion of the intervention, and again 4 weeks after. The outcome measures were performed in both groups which consisted of the pulmonary function tests, 6-min walk test (6MWT), chest measurements and the Manchester Respiratory Activities of Daily Living (MR-ADL) questionnaire. Results Significant improvements were observed after 4 weeks from cessation of MET intervention when compared to baseline for pulmonary function measures (p < 0.001), chest measurements (p < 0.001) and ADLs (p < 0.001), in subjects enrolled in the intervention group. Conclusions Significant short-term effects in outcome measures following 4 weeks from completion of the MET programme were observed in the intervention group. Clinical trial registration: The study was clinically registered in ClinicalTrials.gov (NCT04773860)
