| description | Traditional methods for evaluating postoperative human motion in orthopedics suffer from high equipment costs, time-consuming detection processes, and can only provide static two-dimensional image information. To improve the efficiency and accuracy of postoperative human motion assessment in orthopedics, this study proposes an improved algorithm on the basis of kinematic constraints and inertial measurement units for postoperative human motion assessment in orthopedics. Compared with other methods, the average error and standard deviation of measuring human joint range of motion after orthopedic surgery based on inertial measurement units were the smallest. The average error and standard deviation of measuring human wrist joint range of motion were 1.23° and 1.63°, respectively. The efficiency and accuracy of measuring human joint range of motion after orthopedic surgery based on inertial measurement units were the highest. The efficiency and accuracy were 4s and 98%, respectively. The accuracy of calculating the human joint Angle after orthopedic surgery based on kinematic constraints is also better than other traditional algorithms. The method has high accuracy and applicability, which can effectively improve the monitoring efficiency of postoperative human motion assessment in orthopedics, reduce the error of postoperative human motion assessment in orthopedics, and effectively support personalized management and intervention, further providing reference for the optimization of postoperative human motion assessment in orthopedics. |
