Investigation of hip joint kinematics at different walking speeds in unilateral transtibial amputees

Öz

Purpose: The study was planned to examine hip joint kinematics in 3-dimesional at different walking speeds of individuals with unilateral transtibial amputation. Method: Twenty individuals, including unilateral transtibial amputation (n=10) and healthy individuals (n=10), were included in the study. The hip joint kinematics of the individuals were evaluated with a 3-dimensional motion analysis system during walking at normal speed, 80% and 120% of normal speed on the treadmill. Results: As a result of the study, there was a difference in the measurements made in the sagittal plane between the groups at different walking speeds of the individuals (p<0.05). It was observed that hip movements in the prosthetic extremity in amputees were higher than the unaffected extremity in the sagittal plane (p<0.05). Conclusion: Hip movements in the sagittal plane vary in direct proportion to walking speed. The asymmetry between the extremities continues at different speeds. For this reason, it was concluded that applications for symmetrical walking at different speeds should be included in rehabilitation programs in amputee rehabilitation.

Unilateral transtibial amputelerde farklı yürüyüş hızlarında kalça eklem kinematiğinin incelenmesi

Öz

Amaç: Çalışma unilateral transtibial amputasyonu olan bireylerin farklı yürüyüş hızlarında kalça eklem kinematiklerinin 3 boyutlu olarak incelenmesi amacıyla planlandı. Yöntem: Çalışmaya unilateral transtibial amputasyonu olan (n=10) ve sağlıklı bireyler(n=10) olmak üzere 20 birey dahil edildi. Bireylerin kalça eklem kinematikleri yürüme bandı üzerinde normal hızda, bu hızın %80’inde ve %120’sinde yapılan yürüyüşlerde 3 boyutlu hareket analiz sistemi ile değerlendirildi. Bulgular: Çalışma sonucunda bireylerin farklı yürüyüş hızlarında ve bu hızlarda gruplar arasında sagittal düzlemde yapılan ölçümlerde fark bulundu (p<0,05). Ampute bireylerde protezli ekstremitede kalça hareketlerinin sagittal düzlemde etkilenmemiş ekstremiteden fazla olduğu görüldü (p<0,05). Sonuç: Sagittal düzlemdeki kalça hareketleri yürüyüş hızı ile doğru orantılı olarak değişkenlik göstermektedir. Ekstremiteler arasındaki asimetri farklı hızlarda da devam etmektedir. Bu nedenle ampute rehabilitasyonunda farklı hızlarda da simetrik yürüyüşe yönelik uygulamaların rehabilitasyon programlarına dahil edilmesi gerektiği görüşüne varıldı.
