Abstract

A model describing the kinematics and dynamics of the lower limb is presented. The lower limb is modeled as a sequence of four rigid links connected by three universal rotary joints representing the hip, knee and ankle joints. Each joint is modeled as a sequence of three single axis rotational joints thus ascribing to the lower limb a total of 12 degrees of freedom. A method is described to measure the gait variables so that all nine angles can be computed based on the positions of nine markers placed on the subject during a gait study. The gait variables are then used in an iterative Newton-Euler formulation to compute the moments exerted about the axes of each joint during gait.

Biomechanics of the knee joint
2022, Human Orthopaedic Biomechanics: Fundamentals, Devices and Applications
The knee joint is the largest and one of the most complex joints in the human body. It is positioned between the hip and ankle joints, and this position makes it highly vulnerable to damage due to the high moments that can be generated by the two long lever arms (femur and tibia) of the adjacent joints. It is, therefore, not surprising that this joint is one of the most frequently damaged, not only in terms of bone fracture but also in terms of soft tissue injuries (ligaments and cartilage).
Although the knee joint is a single structure, from a practical point of view, it can be considered being composed of two main joints: the tibio-femoral joint, which is the joint between the distal femur and the proximal tibial, and the patello-femoral joint, which is the joint between the posterior part of the patella and the femoral trochlear groove.
However, from a biomechanical and functional point of view, it is more appropriate to consider the knee joint being composed of three joints, further subdividing the tibio-femoral joint into the medial and lateral tibio-femoral joints characterized by different shapes, different kinematics, and different relative kinetics.
Overall, the kinematics of the knee is a complex three-dimensional roto-translational motion that is strongly related to the patient’s anatomy. In particular, the shape of the femoral condyles, the tibial plateau, and the patellar bone, and the morphological and mechanical properties and position of the soft tissue envelope are critical to producing this motion. For these reasons, knee kinetics and kinematics vary from individual to individual.
Performance verification of different control schemes in human lower extremity rehabilitation robot
2021, Results in Control and Optimization
Many people experience temporary or permanent impairment sometime in their lifetime. Exoskeleton robot-based exercise machines for neurorehabilitation offer an attractive alternative for many disabled people. The performance of exoskeleton robot-based physiotherapy depends on the effectiveness of the robot control scheme. This paper examines the performance of three commonly used control algorithms in serial manipulators. Before examining the performance of the control schemes, it is essential to establish a model for plant dynamics. A dynamic model of the human lower extremity (HLE) is developed first. The Lagrange energy method is used for developing the HLE model. Since the dynamics of a serial manipulator is inherently nonlinear, a nonlinear control scheme would appear effective in dealing with the nonlinear robotic system. Two nonlinear control schemes (computed torque controller and sliding mode controller) and one linear controller (PID) are used to control the robot. The performance of the three control schemes is examined when disturbance torques and/or variations in robot parameters are present. The pros and cons of linear and nonlinear control schemes are discussed. Finally, a detailed discussion on controller selection criteria is presented, including how it can facilitate the selection of a suitable controller.
Causal relationships between immediate pre-impact kinematics and post-impact kinetics during drop landing using a simple three dimensional multibody model
2021, Journal of Biomechanics
This study aimed to validate a simple dynamic model of single-leg drop-landing to develop a methodological foundation for investigating mechanistic causes of anterior cruciate ligament (ACL) injury and to explore mechanical associations between knee valgus torque and landing kinematics that are considered clinically as a high-risk landing posture for the injury. A triple-inverted-pendulum model in three-dimensional space, composed of rigid-links of head-arms-trunk (HAT), thigh and shank, was employed. We derived causal relationships that can predict post-impact kinetics, including impact ground reaction forces (GRFs) and corresponding knee joint torques from a given body-kinematics immediately before impact, based on an assumption of a completely inelastic collision between a landing foot (the distal end-point of the shank in the model) and the ground. The concordance correlation coefficient (CCC) analysis revealed that our model can achieve an acceptable agreement between experimentally measured and model-predicted impact GRFs and corresponding knee joint torques. The $95 %$ one-tailed lower confidence limit of CCC of vertical, mediolateral GRFs and the varus/valgus torque were $0.665 > ρ_{c, a} = 0.643, 0.786 > ρ_{c, a} = 0.758$ and $0.531 > ρ_{c, a} = 0.508$ , respectively, for the least acceptable values $ρ_{c, a}$ . Using this model, effects of three types of hypothetical pre-impact kinematics with modulated (i) medial/lateral leaning HAT angle, (ii) forward/backward HAT tilt-angle, and (iii) knee flexion/extension angle on the impact GRF and corresponding knee joint torque were evaluated. We showed that the smaller knee flexion and the greater HAT leaning toward the landing-limb-side, the larger the knee valgus torque is generated, as a mechanical consequence between the specific pre-impact kinematics and the knee loading associated with the risk of ACL injury. Further exploration of hypothetical kinematics using the model in the future work might contribute to identifying the risky landing kinematics beyond experimental limitations.
