Fonksiyonel Kalça Kalibrasyon Hareketlerinin Serebral Palsili Çocuklarda Yürüyüş Analizinin Kinematik Verilerine Etkileri

Öz

Amaç: Fonksiyonel kalça kalibrasyon hareketlerinin yürüyüş analizinde kalça eklem merkezi üzerine etkilerini inceleyen çalışmalar bulunsa da bu kalibrasyon hareketlerinin kliniğe yansımaları incelenmemiştir. Bu çalışmanın amacı üç farklı fonksiyonel kalibrasyon hareketi (Fleksiyon/Ekstansiyon-Abduksiyon/Adduksiyon-Sirkümdüksiyon (FAC), Modifiye Star Hareketi (Mstar) ve Kontralateral Taraf Modifiye Star Hareketi (CsMstar)) ile elde edilen kalça eklem merkezlerinin yürüyüş analizi kinematik sonuçlara etkilerinin incelenmesidir. Gereç ve Yöntem: Çalışmaya 23 serebral palsili (10 kız, 13 erkek, ortalama yaş: 15.57 ±7.55 yıl) katılımcı dâhil edildi. Üç farklı kalibrasyon hareketi yapılarak yürüyüş analizinde kalça eklem merkezi fonksiyonel metot ile belirlendi. Üç boyutlu yürüyüş analizi yapılarak alt ekstremitelerin kinematik verileri elde edildi. Fonksiyonel kalça eklem merkezlerinin kinematik sonuçlar üzerine etkileri Yürüyüş Profil Skoru (GPS) ve pik kinematik değerler kullanılarak değerlendirildi. Ayrıca, kinematik verilerin dalga formlarının kök ortalama kare farkı (RMS) ve ortalama farkı incelendi. Bulgular: FAC kalibrasyon hareketi ile elde edilen GPS değeri, Mstar ve CsMstar’a göre istatistiki olarak farklılık gösterdi (p<0,001). Ortalama GPS değerleri arasındaki fark FAC ile Mstar arasında 0,34o, FAC ile CsMstar arasında ise 0,29o idi. FAC ile Mstar arasındaki pik kinematik değerleri farkı en fazla diz ekleminde sagittal planda (1,95o), FAC ile CsMstar arasında ise kalça ekleminin sagittal planında (1,87o) olduğu saptandı. Kalça ve diz ekleminin kinematik dalga formunun RMS farkları 3o’nin altında bulundu. Sonuç: Yürüyüş analizinde üç farklı kalibrasyon hareketleri kullanılarak elde edilen kalça eklem merkezleri, kinematik parametrelere klinik açıdan etki etmemişlerdir. Serebral palsili çocukların yürüyüş analizi için fonksiyonel kalça eklem merkezinin belirlenmesinde üç hareketten biri kullanılabilir.

The Effects of Functional Hip Calibration Movements on the Kinematic Data of Gait Analysis in Children with Cerebral Palsy

Öz

Objective: Although there are studies investigating the effects of functional hip calibration movements on the hip joint centre in gait analysis, the clinical reflections of these calibration movements have not been examined. The aim of the present study is to examine the effects of hip joint centres obtained with three different functional calibration movements (Flexion/ Extension-Abduction/Adduction-Circumduction (FAC), Modified Star Motion (Mstar) and Contra Lateral Side Modified Star Motion (CsMstar)) on kinematic outcomes. Material and Method: Twenty-three participants with cerebral palsy (10 female, 13 male, mean age: 15.57 ±7.55 years) were included in the study. The hip joint centre was determined by using the functional method in gait analysis by performing three different calibration movements. Kinematic data of the lower extremities were obtained via three-dimensional gait analysis. The effects of functional hip joint centres on kinematic results were evaluated by using the Gait Profile Score (GPS) and peak kinematic values. In addition, the root mean square difference (RMS) and the mean difference of the kinematic waveforms were investigated. Results: GPS value, obtained with FAC calibration movement, was statistically different from Mstar and CsMstar (p<0.001). The difference between the mean GPS values is 0.34o between FAC and Mstar, and 0.29o between the FAC and CsMstar. The difference in peak kinematic values between FAC and Mstar was found to be highest in the sagittal plane (1.95o) in the knee joint, and between the FAC and CsMstar in the sagittal plane of the hip joint (1.87o). The RMS differences of the kinematic waveform of the hip and knee joint were found below 3o. Conclusion: Hip joint centres obtained by using three different calibration movements in gait analysis did not alter the kinematic parameters clinically. One of the three movements can be used to determine the functional hip joint centre for gait analysis of children with cerebral palsy.
