Yeni Diz Protezleri Geliştirmede Dinamik Yönlendirme (FD) Simülasyonunun Rolü

Amputees face several gait deficits due to their mechanically passive prostheses' lack of control and power. Of crucial importance among these deficits are those related to balance, as falls and a fear of falling can cause an avoidance of activity that leads to further debilitation. A transfemoral an artificial limb replaces a missing leg above the knee. A transfemoral prosthesis consists of a socket, knee, shank, foot, and mechanism for the suspension. The current 3D neuromuscular model of a healthy person in this study is adjusted to depict a transfemoral amputee with a 3R60. The model is simulated by Matlab 2019b Simulink program with a walking speed of 0.9 m/s and 1.2 m/s. The model's performance is assessed by comparing the distinctions between the healthy model and the amputee to the literature results. The amputee gait simulated is in keeping with the literature, particularly at speeds of 1.2 m/s. The oscillations of the model in the coronal plane are 0.9 m/s, indicating that balance is difficult to maintain. A case study was also conducted with a gyroscope control moment in the prosthetic shank on fall prevention. The gyroscope control moment enhances flexing the knee and extending it to prevent a drop. The step was more balanced with the extra control time whirligig at 1.2 m/s.
