Turnip, et al. Effect of treadmill vs ergocycle exercise on COPD patients http://mji.ui.ac.id 42 Med J Indones, Vol. 23, No. 1, February 2014 Comparison of the effects of treadmill and ergocycle exercise on the functional capacity and quality of life of patients with chronic obstructive pulmonary disease Abstrak Latar belakang: Latihan fsik diharapkan dapat memperbaiki kapasitas fungsional dan kualitas hidup pada penderita penyakit paru obstruktif kronik (PPOK). Penelitian ini bertujuan untuk menilai perbedaan antara latihan jentera dan sepeda statis terhadap perubahan kapasitas fungsional dan kualitas hidup pada pasien PPOK stabil. Metode: Penelitian eksperimental dengan pengamatan berulang sebelum dan sesudah perlakuan dilakukan pada 44 subjek dengan PPOK yang datang ke poli Rehabilitasi Medik RS Persahabatan. Latihan sepeda statis dilakukan pada 22 subjek dan latihan jentera pada 22 subjek. Kapasitas fungsional dinilai dengan metode uji jalan 6 menit (UJ6M) dengan mengukur jarak berjalan dalam lintasan 30 meter bolak-balik selama 6 menit, dilakukan minggu I, V dan IX. Penilaian kualitas hidup diukur menggunakan kuesioner St. George’s Respiratory Questionnaire (SGRQ) pada minggu I dan IX dengan mengisi sendiri kuesioner yang diberikan kepada subjek. Program latihan dilakukan selama 8 minggu dengan dosis latihan berdasarkan hasil uji latih pada minggu I. Hasil: Latihan jentera dan sepeda statis menghasilkan perbaikan signifkan dalam hasil uji jalan 6 menit dan SGRQ sejak minggu I sampai IX. Latihan jentera lebih baik dalam meningkatkan jarak tempuh jalan 6 menit dibandingkan sepeda statis secara konsisten pada minggu I-V, V-IX dan I-IX (p < 0,001). Untuk nilai SGRQ, hasil kedua latihan tidak berbeda signifkan. Kesimpulan: Latihan jentera menghasilkan peningkatan kapasitas fungsional yang lebih besar dan berbeda bermakna dibandingkan kelompok latihan sepeda statis pada subjek PPOK stabil. Sedangkan kualitas hidup tidak berbeda bermakna anara kedua jenis latihan. Abstract Background: Physical excercises are hoped to improve functional capacity and quality of life of patients with chronic obstructive pulmonary disease (COPD). This study is aimed to assess the differences between treadmill and ergocycle exercise on changes in functional capacity and quality of life in patients with stable COPD. Methods: This is an experimental study with complete randomization and repeated pre- and post-intervention observation. The study was conducted on 44 subjects with COPD who were presented at Persahabatan Hospital, Medical Rehabilitation Clinic, consisting of 22 subjects undergoing ergocycle exercise and 22 subjects undergoing treadmill exercise test. Functional capacity was assessed by using the 6 minutes walking test (6 MWT) performed at week I, V and IX. Quality of life was measured using the St. George’s Respiratory Questionnaire (SGRQ) at week I and IX. Training program was conducted for 8 weeks with exercise dosage based on the results of exercise test on week I. Results: Treadmill and ergocycle exercise produce signifcant improvement in both the 6 MWT and SGRQ test since week I to IX. But in comparison, treadmill exercise improves 6 MWT distance better than ergocycle consistently at week I-V, V-IX and I-IX (p < 0.001). For the SGRQ score, both exercises did not differ signifcantly. Conclusion: Treadmill exercise is associated with signifcantly better improvement in functional capacity compared to ergocycle exercise in stable COPD subjects. Concerning quality of life, both exercises gave an equivalent improvement in stable COPD subjects.
