Abstract
Introduction: Limited progressive air flow in Chronic Obstructive Pulmonary Disease (COPD) can caused by small airway disease (bronchiolitis obstructive) and loss of elasticity of the lung (emphysema). Further it can be decreasing the quality of life in COPD patients because dyspnea and uncomfortable in activity. Progressive muscle relaxation (PMR) is one of the relaxation technique that can repair pulmonary ventilation by decreasing chronic constriction of the respiratory muscles. The objective of this study was to analyze the effect of progressive muscle relaxation on raised peak expiratory flow rate (PEFR).Methods: A pre-experimental one group pre-post test design was used in this study. Population was all of the COPD patients at Pulmonary Specialist Polyclinic Dr Mohamad Soewandhie Surabaya. There were 8 respondents taken by using purposive sampling. PEFR was counted by using peak flow meter every six day. Data were analyzed by using Paired t-Test with significance level p≤0.05.Results: The result showed that PMR had significance level on increasing of PEFR (p=0.012).Conclusion: It can be concluded that PMR has an effect on raise PEFR. Further studies are recommended to measure the effect of PMR on respiratory rate (RR), heart rate (HR) subjective dyspnoe symptoms, forced expiration volume on the first minute (FEV1) and mid maximum flow rate (MMFR) in COPD patients.

Summary
One group pre-post test purposive sampling design. Sampel diambil sesuai dengan kriteria inklusi yang telah ditentukan sebagai berikut: penderita PPOK yang kooperatif dan bersedia menjadi responden, penderita PPOK tanpa komplikasi (terutama gangguan vaskuler seperti hipertensi), penderita PPOK yang tidak mengalami eksaserbasi akut, penderita PPOK berusia >50 tahun dan penderita PPOK tinggal di Surabaya dan dapat dijangkau oleh peneliti. Variabel independen dalam penelitian ini adalah latihan relaksasi progressive muscle relaxation, sedangkan variabel dependen adalah penurunan sesak nafas dengan parameter PEFR. Setiap observasi terdapat peningkatan rerata nilai PEFR sesuai dengan grafik pada tabel 1 yang ditunjukkan dengan nilai ∆ rerata post-pre yang terus meningkat hingga observasi terakhir meskipun berfluktuasi. Pada observasi ke 5 mulai didapatkan nilai yang bermakna dengan ∆ rerata post-pre [16,25] dan nilai p=0,042 meskipun pada observasi ke-6 menjadi kurang bermakna dengan ∆ rerata post-pre 10,00 dan p=0,121 namun di akhir observasi ke-7 dan 8 kembali didapatkan hasil yang berturut-turut signifikan dengan p
