“…However, no conclusive consensus has been reached on reducing impact force because the mechanism for these improvements is still not well understood, and systematic studies of tibiofemoral forces (TFFs) during CPM cycles are lacking. The postoperative rehabilitation of fractures and KA are sensitive to knee joint stress [16]; thus, it is necessary to quantify and decrease this stress during early rehabilitation [17,18]. In addition, the estimated TFFs can be used to plan rehabilitation treatments and monitor abnormal forces during the rehabilitation process.…”

Continuous passive motion (CPM) machines are commonly used after various knee surgeries, but information on tibiofemoral forces (TFFs) during CPM cycles is limited. This study aimed to explore the changing trend of TFFs during CPM cycles under various ranges of motion (ROM) and body weights (BW) by establishing a two-dimensional mathematical model. TFFs were estimated by using joint angles, foot load, and leg–foot weight. Eleven healthy male participants were tested with ROM ranging from 0° to 120°. The values of the peak TFFs during knee flexion were higher than those during knee extension, varying nonlinearly with ROM. BW had a significant main effect on the peak TFFs and tibiofemoral shear forces, while ROM had a limited effect on the peak TFFs. No significant interaction effects were observed between BW and ROM for each peak TFF, whereas a strong linear correlation existed between the peak tibiofemoral compressive forces (TFCFs) and the peak resultant TFFs (R2 = 0.971, p < 0.01). The proposed method showed promise in serving as an input for optimizing rehabilitation devices.

“…Understanding their mutual effects is of great value in different fields, including performance enhancement in competitive swimming [4,5], effect improvement in rehabilitation training [6], and design optimization of underwater exoskeletons [7]. Research on human swimming dynamics started from the end of the last century, and currently, the mainstream methods are computational fluid dynamics (CFD) [8][9][10][11][12][13][14][15][16][17], experiments [18][19][20][21][22][23][24][25], and multi-rigid body dynamics [26][27][28][29][30].…”

“…One way to tackle the above issues is to develop models and to perform analysis based on multibody system dynamics, as relevant research is scarce [26][27][28]. The most representative work comes from Nakashima et al [30]; they established a multi-rigid-body dynamic model of human swimming based on Newton-Euler equations.…”

Swimming is a kind of complex locomotion that involves the interaction between the human body and the water. Here, to examine the effects of currents on the performance of freestyle and breaststroke swimming, a multi-body Newton-Euler dynamic model of human swimming is developed. The model consists of 18 rigid segments, whose shapes and geometries are determined based on the measured data from 3D scanning, and the fluid drags in consideration of the current are modeled. By establishing the interrelations between the fluid moments and the swimming kinematics, the underlying mechanism that triggers the turning of the human body is uncovered. Through systematic parametric analyses, the effects of currents on swimming performance (including the human body orientation, swimming direction, swimming speed, and propulsive efficiency) are elucidated. It reveals that the current would turn the human body counterclockwise in freestyle swimming, while clockwise in breaststroke swimming (which means that from the top view, the human trunk, i.e., the vector pointing from the bottom of feet to the top of the head, rotates counterclockwise or clockwise). Moreover, for both strokes, there exists a critical current condition, beyond which, the absolute swimming direction will be reversed. This work provides a wealth of fundamental insights into the swimming dynamics in the presence of currents, and the proposed modeling and analysis framework is promising to be used for analyzing the human swimming behavior in open water.
