Abstract
Üst ekstremite fonksiyon değerlendirilmesinde
kullanılan yöntemlerden birisi de Eklem Hareket Açıklığı (EHA)
ölçümleridir. Günümüzde bu ölçümler klinisyenin gözlemsel
değerlendirmesine ve/veya gonyometrik ölçümlere
dayanmaktadır. Bu ölçümlerde tekrarlanabilirlik ve güvenilirlik
açısından problemler mevcuttur. Bu çalışmada üst ektremitede
EHA ölçümlerinin sayısal değerlendirilmesine bağlı olarak
objektif çıkarımlar yapılmasını sağlayabilecek tek kameralı bir
sistem önerilmiştir. Bireylerin omuz ve dirsek fleksiyonu
hareketleri kaydedilmiştir. Eş zamanlı olarak “Altın Standart”
olarak OptiTrack sistemi ile de yapılan hareketler kayıt altına
alınmıştır ve analiz edilmiştir. Çalışmaya 9 erkek ve 9 kadın
birey katılmıştır. Hareketlerin kaydedilmesi için Kinect kamera
kullanılmıştır. Kinect kamera OptiTrack sistemi ile
karşılaştırılmıştır. Omuz ve dirsek fleksiyonu açıları her iki
sistem ile hesaplanmıştır. Hesaplanan açılar kullanılarak her iki
sistemin uyumu istatiksel olarak incelenmiştir. Bland- Altman
yöntemi kullanılarak yapılan analizlerde hem erkek hem de
kadın bireylerde omuz fleksiyonu ve dirsek fleksiyonu
hareketleri açısından %95 güven aralığında her iki kameranın
birbiriyle uyumlu olduğu tespit edilmiştir. Bu çalışma önerilen
sistemin klinik tanı için güvenirliğine dair delil teşkil etmektedir.
One of the methods used in upper extremity function assessment is the Range of Motion (ROM) measurements. In practice, these measurements are performed by a clinicians' personal observations and/or goniometric measurements. In these measurements, there are some problems related to repeatibility and reliability criterias. In this study, a novel system which contains only a single camera to perform ROM calculations objectively in upper extremity is suggested. For this purpose shoulder and elbow flexion movements were recorded and analyzed. The system was compared with which was known as a Gold Standard system. The nine male and nine female volunteers were participated in the study. Kinect camera was used to record movements of upper limb. The Kinect camera results were compared with that of OptiTrack camera system. The shoulder and elbow flexion angles were computed for both systems. The agreement between the two systems were examined statistically by using the computed ROM values. Bland-Altman plots revealed the agreement within 95% interval of confidence, between the two systems for shoulder flexion and elbow flexion in both males and females. This study provides evidence for the suitability of the proposed system for a clinical work.
