Abstract
Objective: The aim of this study was to investigate dynamic balance in bilateral knee osteoarthritis (KO)patients with varus deformity in relation to the functional disability.Methods: Fifty-eight patients (54 women and 4 men) with KO with significant varus deformity and thirty-five(31 women and 4 men) controls of same age, gender,weigth, heigth and body mass index group were tested using Biodex Stability System (Biodex medical systems, Shirley, NY). Anterior / Posterior Index (AP), Medial/ Lateral Index (ML) and Overall Index (OA) were obtained with bilateral stance at a platform stability of 8.Subjects were tested with "eyes open" all times. Lequesne index was used for the assessment of disability in the patients with knee OA. Results: Overall, Anterior/Posterior, and Medial/Lateral indices in KO group were significantly higher than control group. For OA index, the results were 4.02 ± 1.48 in KO, 3.12± 1.42 in the control group (p:0.001). For AP index, the results were 3.01 ± 1.09 in KO, 2.52 ± 1.24 in the control group (p:0.012). For ML index,the results were 2.76± 1.27 in KO and 2.09 ± 1.10 in the control group (p: 0.003). Statistically significant correlation was found between Lequesne pain score and ML stability index (r:0.266 p:0.042). A similar correlation was determined between Lequesne daily living activities score and OA and AP stability indices ( respectively; r:0.276 p:0.033; r:0.305 p:0.18). However, a positive correlation was not detected between total Lequesne index score and postural balance for all of three stability indices. Conclusion: KO with significant varus deformity has negative effect on the postural stability. Results suggest the importance of balance training in this population.
Özet
Amaç: Varus deformitesi olan bilateral diz osteoartritli (OA) hastalarda dinamik olarak dengeyi değerlendirmek ve bunun fonksiyonel dizabilite ile ilişkisini araştırmaktır. Metodlar: 58 ileri düzeyde varus deformitesi olan diz OA'li hasta (54 kadın ve 4 erkek) ve aynı yaş, cinsiyet, boy, kilo, vücut kitle indeksine sahip 35 kontrol (31 kadın ve 4 erkek) çalışmaya alındı. Bireylerin postural dengesi, Biodex Stabilite Sistemi (Biodex medical systems, Shirley, NY) ile her iki ayak yere basarken, gözler açık olacak şekilde, 8. düzey platform stabilitesinde değerlendirildi ve Anterior/Posterior (AP), Medial/lateral (ML) ve Overall (OA) indeksleri saptandı. OA'li hastalarda, dizabiliteyi değerlendirmek amacıyla Lequesne indeksi uygulandı. Bulgular: Diz OA'li grupda OA, AP ve ML indeksleri kontrol grubuna göre istatistiksel olarak anlamlı derecede daha yüksek saptandı (Overall indeks OA'li grupda 4.02±1.48, kontrol grubunda 3.12±1.42 (p:0.001), AP indeks OA'li grupda 3.01±1.09, kontrol grubunda 2.52± 1.24 (p:0.012), ML indeks OA'li grupda 2.76±1.27, kontrol grubunda 2.09±1.10, (p:0.003)). Lequesne indeksinin toplam skoru ile stabilite indeksleri arasında istatistiksel olarak anlamlı bir korelasyon saptanmazken, Lequesne ağrı skoru ile ML stabilite indeksi arasında (r:0.266, p:0.042), Lequesne günlük yaşam aktiviteleri skoru ile OA ve AP stabilite indeksleri arasında istatistiksel olarak anlamlı korelasyon tespit edildi (sırasıyla; r:0.276, p:0.033; r:0.305, p:0.018). Sonuç: Varus deformitesinin eşlik ettiği diz OA'i postural stabiliteyi olumsuz olarak etkiler. Bulgular bu populasyonda denge eğitiminin önemini akla getirir.
