Parkinson Hastalarında Sensör Temelli Yürüme Analizi

Yürüyüş bozukluğu Parkinson hastalığının (PH) temel semptomlarından biridir. Bu çalışmanın amacı PH hastalarında atalet sensörleri kullanarak yürüme parametrelerini, hastalık şiddeti ile yürüme parametreleri arasındaki ilişkiyi araştırmaktır. Parkinson hastalığı tanısı almış onsekiz hastaya iki dakika yürüme testi yapıldı. Yürüme parametreleri incelendi ve yürüme parametrelerinin MDS-UPDRS Bölüm III ve Hoehn &Yahr (H&Y) ölçeği puanları ile ilişkisi araştırıldı. Çalışmaya yaş ortalaması 65.78 ± 8.07 olan 18 PH tanılı hasta (sekiz kadın, on erkek) dahil edildi. Ayak vuruş açısı (r=-0,66), dönüş açısı (r=-0,73), adım uzunluğu (r=-0,52) ve dönüş hızı (r=-0,54) MDS-UPDRS bölüm III skoru ile negatif, dönüş süresi (r=0,58) ile pozitif korelasyon, gösterdi (p<0,05). H&Y evrelemesi, ayak vuruş açısı (r=-0.58), parmak uç açısı (r=-0.53) ile negatif, dönüş süresi (r=0.56) ve dönüş hızı (r=-0.52) ile pozitif korelasyon gösterdi.Atalet sensörleri ile Parkinson hastalarının klinik değerlendirmesini destekleyen objektif yürüyüş parametreleri sağlanabilir.

Sensor-Based Gait Analysis in Patients with Parkinson Disease

Gait impairment is one of the cardinal signs of Parkinson disease (PD). This study aims to investigate gait parameters using inertial sensors and evaluate the relation between disease severity and gait parameters. Two-minute walkway tests were performed on eighteen patients with PD. Gait parameters were analyzed and the relation between gait parameters and the scores of MDS-UPDRS Part III and the Hoehn &Yahr (H&Y) scale is investigated. Eighteen PD patients (eight female, ten male) with a mean age of 65.78 ± 8.07 were included in the study. Foot strike angle(r=-0.66), turn angle (r=-0.73), stride length (r=-0.52), and turn velocity (r=-0.54) showed negative, turn duration (r=0.58) showed a positive correlation with the score of MDS-UPDRS part III, (p<0.05). H&Y staging showed a negative correlation with foot strike angle (r=-0.58), toe off angle (r=-0.53), and turn velocity (r=-0.52), a positive correlation with turn duration (r=0.56). Inertial sensors may provide objective gait parameters supporting the clinical assessment of patients with PD.
