ABSTRACT
Aim: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are a major complication of COPD and a leading cause of hospitalization, detrimentally affecting functional exercise capacity. The 6-minute walk test (6MWT) is a reliable measure of exercise capacity in chronic lung diseases. Conversely, the 1-minute sit-to-stand test (1STST) offers a simpler assessment of physical function. The aim was to demonstrate the association of functional exercise capacity assessed by 1STST and 6MWT in COPD patients with acute exacerbation.
Materials and Methods: In this study, 37 hospitalized patients with acute exacerbation COPD (mean age:66 years) underwent assessments including pulmonary function testing, 6MWT, 1STST and modified Medical Research Council (MMRC). Parameters such as heart rate, oxygen saturation, and perceived dyspnea (via the modified Borg scale) were monitored during tests.
Results: The results showed a significant correlation between 6MWT and 1STST performance (r=0.656, p<0.001). Notably, end-tidal oxygen saturation differed between tests, with the 6MWT showing higher end-tidal dyspnea scores. During recovery, 1STST induced increased heart rate and decreased oxygen saturation. Both 6MWT and 1STST were negatively associated with age and MMRC. Positive correlations were observed between 6MWT and FEV1(L) and PEF(L).
Conclusions: Similar to the 6MWT, the 1STS test may be used to evaluate how well patients with AECOPD perform during functional exercise. We propose that the 1STST is a suitable alternative to the 6MWT for the assessment of functional exercise performance during hospitalization in AECOPD patients.

Akut Alevlenmesi Olan KOAH Hastalarında Altı Dakika Yürüme Testi ile Bir Dakika Otur Kalk Testi Arasındaki İlişki

ÖZ
Amaç: Akut alevlenme dönemleri, Kronik obstrüktif akciğer hastaları (KOAH) için önemli bir komplikasyon ve hastaneye yatışın önde gelen nedenlerinden biridir. Bu durum fonksiyonel egzersiz kapasitesini olumsuz yönde etkiler. Altı dakika yürüme testi (6DYT) kronik akciğer hastalıklarında egzersiz kapasitesinin değerlendirilmesinde kullanılan güvenilir bir testtir. Öte yandan, 1 dakika otur-kalk testi fiziksel fonksiyonun daha basit bir değerlendirmesini sunar. Bu çalışmada akut alevlenen KOAH hastalarında, fonksiyonel egzersiz kapasitesinin değerlendirilmesinde kullanılan 6DYT ve 1 dakika otur kalk testinin arasındaki ilişkinin gösterilmesi amaçlanmıştır.
Gereç ve Yöntem: Hastanede yatan 37 akut alevlenen KOAH hastasına (ortalama yaş: 66 yıl) solunum fonksiyon testi, 6DYT, 1 dakika otur kalk testi ve Modifiye Medical Research Council (MMRC) ölçeği ile değerlendirmeler yapıldı. Testler sırasında kalp hızı, oksijen satürasyonu ve algılanan dispne parametreleri (modifiye Borg ölçeği) izlendi.
Bulgular: 6DYT ile 1 dakika otur kalk testinin performansı arasında anlamlı bir korelasyon bulunmuştur (r=0.656, p<0.001). Özellikle, test sonu oksijen satürasyonu testler arasında farklılık göstermiştir ve test sonu bulgularında 6DYT daha yüksek dispne algısına sebep olmuştur. Toparlanma sırasında, 1 dakika otur kalk testinin vital bulgularında kalp hızında daha fazla artış ve oksijen satürasyonunda daha fazla düşüş görülmüştür. Hem 6DYT hem de 1 dakika otur kalk testi yaş ve MMRC parametreleri ile negatif ilişkiliydi. 6DYT ile FEV1(L) ve PEF(L) arasında pozitif korelasyon gözlenmiştir.
Sonuç: Altı-DYT gibi, 1 dakika otur kalk testi de akut alevlenen KOAH hastalarının fonksiyonel egzersizin değerlendirilmesi sırasında kullanılabilir. Akut alevlenen KOAH hastalarında hastanede yatış sırasında fonksiyonel egzersiz performansının değerlendirilmesi için 1 dakika otur kalk testini 6DYT'nin yerine uygun bir alternatif olarak öneriyoruz.
