Summary: Inertial measurement units (IMUs) are widely used for evaluating human motion outside the laboratory. However, accurately quantifying upper limb motion using IMUs is still challenging. This systematic review evaluates different computational methods for converting IMU data to joint angles in the upper limb and assesses their accuracy compared to optoelectronic motion analysis. The review finds that the highest accuracy is achieved using Euler angle decomposition and Kalman-based filters. The study also highlights the difficulties in accurately tracking scapulothoracic and glenohumeral joint motion due to skin motion artifacts. Future research should focus on implementing functional joint axis calibrations and IMU-based scapula locators to address these challenges.

Summary: This article proposes a motion-capture method based on inertial sensors to analyze the synchronized movements of two canoeists. The results show a significant correlation between the shoulder joint angles of the synchronized canoeists and the ability to analyze posture coordination. This research can help evaluate the synchronization effect of synchronized canoeing and improve technical movements, as well as assist coaches in selecting athletes with matching skills and styles.

Summary: This article presents a calibration method for low-cost IMU to improve accuracy by effectively deriving the nonlinear scale factors of the sensors. The validation on both synthetic and real-world data sets showed significantly smaller errors in acceleration and angular velocity compared to existing approaches, demonstrating a remarkable improvement of 64.12% and 47.90%, respectively.

Summary: An increasing number of studies use Principal Component Analysis (PCA) on whole-body kinematic data to analyze posture changes in human movement. This study found that PCA outcomes have strong internal consistency in the lower order Principal Movements (PMs) but start to deviate in the higher order PMs.

Summary: This study investigates the influence of sensor placement for cardiorespiratory monitoring using inertial measurement units (IMUs). Triaxial accelerometer data was collected from 15 healthy volunteers in different postures, and the most informative axis and sensor position were determined. The general-purpose configuration allows accurate estimation of respiratory rate (RR) and heart rate (HR), while the posture-dependent configuration improves RR estimation, especially during walking and standing.

Summary: This study evaluates IMUs as an alternative method to measure joint angle range of motion and compares it to optical motion capture. The results suggest that IMUs can be a viable alternative for sport-specific lower-extremity ROM measurement, but the selection of sensor-to-segment calibration methods should be based on the specific tasks and variables of interest.

Summary: Human motion analysis requires obtaining information about the position and orientation of different parts of the human body over time. Optical methods such as the VICON system and IMU sensors are widely used for this purpose. However, these methods are expensive and have limitations in terms of position and angle acquisition. This paper proposes using a low-cost drone flight controller as a device for human body pose estimation and acceleration measurements. The paper discusses the test setup, compares the efficiency of the flight controller sensor with commercial sensors, and presents the practical usability of these sensors in human motion measurement. The issues related to the dynamic response of IMU-based sensors during acceleration measurement are also discussed.

Summary: This study aimed to evaluate the accuracy and reliability of an inertial measurement unit (IMU) system compared to an optical motion capture (OMC) system in transtibial prosthesis users. Results showed that the IMU system had low intra- and inter-subject variability, with good agreement with the OMC system in sagittal kinematic parameters. Therefore, the IMU system is capable of accurately capturing gait data in lower limb prosthesis users and is a reliable alternative to the OMC system.

Summary: Researchers suggest Telemark skiing as a safer alternative to Alpine skiing, with a free heel and flexible boots as distinguishing features. Their study compared three types of turns in Telemark skiing and found higher velocities in parallel and rotational turns (14.2 m/s and 14.9 m/s, respectively) compared to low-high turns (8.9 m/s). The knee angles showed similar values for parallel and rotational techniques but differed considerably in the low-high technique.

Summary: Inertial sensor motion capture system has advantages of versatility, portability, and affordability, but its accuracy is lower than the optical system. This article proposes a method that includes orientation estimation and calibration to achieve accurate joint angle estimation. Experiments show that the proposed system improves joint measurement accuracy compared with existing inertial sensor-based systems.

Summary: This research evaluated the use of data from a single IMU secured to the lower back of the rider to estimate CoM motion during non-seated cycling. The results showed that the IMU can provide a suitable approach for deriving a cyclist's CoM displacement, but linearly increasing overestimation should be taken into account.

Summary: The implantable motor neuroprostheses can restore functionality by activating paralyzed muscles, and the Networked Neuroprosthesis (NNP) addresses the limitation of the traditional neuroprosthetic systems by being a fully implanted modular system. System testing showed that the NNP is functional and capable of generating stimulus pulses and recording different types of signals. Multiple clinical applications are anticipated based on the successful design, manufacturing, and testing of the NNP System.
