Abstract

Aim: We aimed to investigate the relationship between functional exercise capacity level and muscle strength and lung functions in the lung transplantation (LTx) candidates.

Materials and Methods: Twenty-five patients who were referred to our hospital for the pre-transplantation pulmonary rehabilitation program were included in the study. Patients were divided into 2 groups according to the 6-min walk test walking distance (Group1: 6MWD<350m; n:14, Group2: 6DWD≥350m, n=11).The percentage of muscle and fat masses, peripheral muscle forces were compared and the relationship between the muscle mass, muscle strength, lung functions and the exercise capacity level were examined. 

Results: The groups have similar demographic characteristics (age, body mass index). Muscle masses (p=.956), lean tissue (p=.956), fat masses (p=.827), fat percentages (p = .701) were similar. When the peripheral muscle strengths were compared, the knee extension, elbow flexion and hand grip strengths were similar, and the dorsiflexion muscle strength (p=.039) and FEV1% (p = 0.030) values of group 1 were found to be statistically low. The correlation between 6MWD and other outcome measures, there were moderate correlation with elbow flexion (r =.483; p=.015), dorsiflexion (r =.518; p=.008) and %FEV1 (r =.514; p=.009) and high level correlation with %FVC (r=.605; p=.001).

Conclusion: In our study, the exercise capacities of LTx candidates are independent of muscle and fat mass and are influenced by muscle strength and lung functions. This suggests that exercise capacity is related to primary lung pathology in this patient group. In order to obtain more meaningful results, post-rehabilitation changes should be examined.

Akciğer Nakil Adaylarında Egzersiz Kapasitesinin Periferik Kas Kuvveti Ve Solunum Fonksiyonları İle İlişkisi

Abstract

Amaç: Çalışmamızda akciğer nakil adaylarında fonksiyonel egzersiz kapasitesi seviyesinin, periferik kas gücü ve solunum fonksiyonları ile olan ilişkisini incelemeyi amaçladık.

Gereç ve Yöntem: Hastanemiz pulmoner rehabilitasyon merkezinde, akciğer nakli öncesi rehabilitasyon programına alınması için refere edilen 25 hasta çalışmaya dahil edildi. Hastalar 6 -dakika yürüyüş testi yürüme mesafelerine (6DYM) göre 2 gruba ayrıldı (Grup1: 6DYM<350m, n:14; Grup2: 6DYM≥350m, n=11). Grupların kas ve yağ kütle ve yüzdeleri, periferik kas kuvvetleri karşılaştırıldı, egzersiz kapasitesi seviyesinin kas kütlesi ve solunum fonksiyonları ile olan ilişkisi incelendi. 

Bulgular: Gruplar benzer demografik özelliklere sahipti (yaş, beden kitle indeksi). Kas kütleleri (p=,956), yağsız doku yüzdeleri (p=,956), yağ kütleleri (p=,827) ve vücut yağ yüzdeleri (p=,701) benzerdi. Periferik kas kuvvetleri karşılaştırıldığında diz ekstansiyonu, dirsek fleksiyonu ve el kavrama kuvvetleri benzer olup, Grup1’in dorsifleksiyon kas kuvvetinin (p=,039) ve FEV1% (p=0,033) değerlerinin istatistiksel olarak daha düşük olduğu tespit edildi. 6DYM ile diğer sonuç ölçümleri arasında yapılan ilişki analizinde dirsek fleksiyonu (r=,483; p=,015), dorsifleksiyon (r=,518; p=,008) kas kuvveti ve FEV1% (r=,514; p=,009) ile orta, FVC% (r=,605; p=,001)  ile ise yüksek seviyede korelasyon tespit edildi.

Sonuç: Çalışmamızdaki akciğer nakil adayı olan hastaların egzersiz kapasiteleri, kas ve yağ kütlesinden bağımsız olup, kas kuvvetinden ve solunum fonksiyonlarından etkilenmektedir. Bu durum, bu hasta grubunda egzersiz kapasitesindeki azalmanın daha ziyade primer akciğer patolojisine bağlı olduğunu düşündürmektedir. Daha anlamlı sonuçların elde edilebilmesi için, rehabilitasyon sonrası değişimler incelenmelidir.
