The metabolic efficiency of walking is reduced in patients with intermittent claudication İntermitan klodikasyonu olan hastalarda yürümenin metabolik etkinliği azalir

Amac: Bu calismada intermitan klodikasyon (IK) olan ve saglikli bireylerin tercih ettikleri yurume hizi, yurume oksijen maliyeti acisindan gorulen farklar ve aralarindaki iliski arastirildi ve IK anketi, klodikasyon agri skalasi ve Borg skorlari karsilastirildi. Ca­lis­ma­ pla­ni:­Calismamiza 12 saglikli birey (grup 1) ve IK’li periferik damar hastaligi (PDH) olan 12 hasta (grup 2) katildi, bir saglikli birey ve uc IK’li hasta dislanma kriterleri nedeniyle calismadan cikarildi ve kalan 20 katilimci degerlendirildi (grup 1 n=11, grup 2 n=9). Katilimcilar, indirekt kalorimetri yontemi ile yurume oksijen maliyeti olcumu icin onceden belirlenen hizlarda kosu bandinda yurutuldu. Intermitan klodikasyon anketi test oncesi uygulandi. Bul gu lar: Grup 1’in ortalama yurume hizi 77.8±11.4 m/dk. , grup 2’nin 67.2±10.5 m/dk idi (p<0.05). Saglikli bireylerin ortalama yurume oksijen maliyetleri 0.14±0.02 mL/kg/m, hasta grupta ise 0.18±0.04 mL/kg/m idi (p<0.05). Grup 2’de IK anket skoru ile oksijen maliyeti, tercih edilen yurume hizi, klodikasyon agri skalasi skoru ve Borg skoru arasinda iliski yoktu. Yurume oksijen maliyeti ile maksimum yurume mesafesi (MYM) arasinda anlamli iliski vardi (p<0.05). Klodikasyon mesafesinin, Borg skoru ve klodikasyon agri skalasi skoru ile anlamli iliskisi vardi. So­nuc:­Periferik damar hastaligi olan hastalarda, yurumenin metabolik etkinligi ve tercih edilen yurume hizi azalabilir. Bu calisma yurume oksijen maliyetinin, tercih edilen yurume hizinin, Borg skorunun, klodikasyon mesafesinin ve MYM’nin, IK’li hastalarin hareket kisitliligini izlemek icin kullanilabilecek objektif parametreler oldugunu gostermektedir. Anah tar soz cuk ler: Intermitan klodikasyon; anketler; kosu bandi testi. Background:­We aimed to determine the differences in the preferred walking speed, oxygen cost of walking and their correlations, comparing the intermittent claudication (IC) questionnaire, claudication pain scale and Borg scores in the patients with IC and the healthy subjects. Methods: Twelve healthy subjects (group 1) and 12 patients with IC (group 2) participated in our study, one healthy control subject and three patients with IC were excluded from the study because of exclusion criteria, and remain 20 participants were evaluated (n=11 in group 1, n=9 in group 2). The participants walked on a treadmill at pre-determined speeds for the measurements of oxygen cost of walking by indirect calorimetry method. The IC questionnaire was administered prior to the test. Results:­ The mean walking speed in group 1 was 77.8±11.4 m/min and 67.2±10.5 m/min in group 2 (p<0.05). The mean oxygen cost of the walking trial in healthy subjects was 0.14±0.02 mL/kg/m and 0.18±0.04 mL/kg/m in the patient group (p<0.05). In group 2, there was no correlation between the IC questionnaire score and oxygen cost, preferred walking speed, claudication pain scale score, and Borg score. The oxygen cost of walking was significantly correlated with the maximal walking distance (MWD) (p<0.05). There was a significant correlation between the initial claudication distance and Borg score and claudication pain scale score (p<0.001). Conclusion:­ The metabolic efficiency of gait and the preferred walking speed may be reduced in PAD patients. Our study results suggest that oxygen cost of walking, preferred walking speed, Borg score, claudication pain scale score, initial claudication distance and MWD are objective parameters which can be used in monitoring the ambulatory limitation of PAD patients with IC.
