Unilateral kronik ayak bileği instabilitesi olan bireylerde peroneal kas kalınlığı ve kas kuvvetinin değerlendirilmesi

Abstract

Amaç: Bu çalışmada unilateral kronik ayak bileği instabilitesi olan bireylerde peroneal kas kalınlığı ve kuvvetinin araştırılması amaçlandı. Yöntem: Çalışmaya unilateral kronik ayak bileği instabilitesi olan otuz dört kişi dahil edildi. Unilateral kronik ayak bileği instabilitesi olan kişilerin ayak duruşu Ayak Duruş İndeksi ile, ayak bileği çevresindeki kasların kas gücü elde taşınan dinamometre ile ve peroneus longus ve brevis kas kalınlıkları ultrasonografi ile değerlendirildi. Bulgular: Çalışma sonucunda katılımcıların hem peroneus brevis (p=0,024) hem de peroneus longus (p=0,043) kas kalınlıklarının etkilenen tarafta etkilenmeyen tarafa göre daha ince olduğu görüldü. Katılımcıların etkilenen ve etkilenmeyen taraflarındaki kas kalınlıkları incelendiğinde, plantar fleksör, dorsifleksör, invertör ve evertör kas kalınlıklarının her iki tarafta da benzer olduğu gözlendi (p>0,05). Sonuç: Çalışma sonucunda, unilateral kronik ayak bileği instabilitesi olan bireylerde, Perous Longus ve Brevis kas kalınlığı etkilenen tarafta daha azdı. Ayrıca, unilateral kronik ayak bileği instabilitesi olan bireylerde, etkilenen taraftaki kas kuvvetinde bir fark yoktu.

Evaluation of peroneal muscle thickness and muscle strength in individuals with unilateral chronic ankle instability

Abstract

Aims: The aim of this study was to compare peroneal muscle thickness and ankle circumference muscle strength between the affected and unaffected sides in individuals with unilateral chronic ankle instability. Methods: Thirty-four participants with unilateral chronic ankle instability were included in the study. The foot posture of participants with unilateral chronic ankle instability was evaluated with the Foot Posture Index, the strength of the muscles around the ankle was evaluated with a hand-held dynamometer, and peroneus longus (PL) and peroneus brevis (PB) muscle thicknesses were evaluated with ultrasonography. Since the normal distribution assumption was not met, measurements of the affected and unaffected extremities were compared using the Wilcoxon signed rank test. Results: As a result of the study, both PB (p=0.024) and PL (p=0.043) muscle thicknesses of the participants were thinner on the affected side. When the muscle strength of the participants on the affected and unaffected sides was examined, no statistically significant difference was observed between the two sides for plantar flexor, dorsiflexor, invertor, and evertor muscle strength (p>0.05). Conclusion: As a result, in participants with unilateral chronic ankle instability, PL and PB muscle thickness were less on the affected side. Furthermore, there was no difference in muscle strength between the sides in participants with unilateral chronic ankle instability.
