Usually the measurement of multi-segment foot and ankle complex kinematics is done with stationary motion capture devices which are limited to use in a gait laboratory. This study aimed propose validate wearable system measure joint angles during daily conditions, then investigate its suitability for clinical evaluations. The consisted four segments (shank, hindfoot, forefoot, toes), an inertial unit (3D gyroscopes 3D accelerometers) attached each segment. between were calculated sagittal,...
An inertial measurement unit (IMU) is the ideal technology for ambulatory of human motion. However, because an IMU measures acceleration and angular velocity in its sensor frame, to obtain clinically meaningful kinematics, a calibration procedure required align frame with anatomical corresponding segment. This paper aims investigate whether recording straight walking could be used sensor-to-body IMUs instead performing calibration-specific movements. For this purpose, after three five...
Manual material handling, a common practice in various industries, often involves moving or lifting heavy objects, placing significant physical strain on workers, especially the lower back. A prime example is manhole cover removal, which typically requires handling weights, potentially leading to back muscle strain. This study investigates effectiveness of passive exoskeleton reducing ergonomic risks during removal. Twenty able-bodied workers participated, performing task with and without...
Previous studies assessed the outcome of ankle arthrodesis (AA) and total replacement (TAR) surgeries; however, extent postoperative recovery towards bilateral gait mechanics (BGM) is unknown. We evaluated two surgeries at least 2 years post rehabilitation, focusing on BGM. 36 participants, including 12 AA patients, TAR controls were included. Gait assessment over 50 m distance was performed utilizing pressure insoles 3D inertial sensors, following which an intraindividual comparison...
The Rapid Upper Limb Assessment (RULA) is frequently used to monitor body posture for early risk prevention of work-related musculoskeletal disorders. However, RULA measurements that are based on workers' self-report or external rater observation suffer from low repeatability. Thus, the objective this study was investigate accuracy and repeatability an inertial measurement unit (IMU) system in-field score assessment during manual material handling tasks using 3D Cardan angles 2D projection...
The adoption of robots in rehabilitation medicine settings has become increasingly attractive recent years. Robots are capable providing repetitive, high-intensity physiotherapy. In this paper, we apply kinesthetic teaching principles to a robotic system order allow it first learn and then imitate therapist's behavior while assisting patient lower-limb therapy task. A assistance lifting during treadmill-based gait is statistically encoded by the using Learning-from-Demonstration (LfD)...
Lower extremity kinematic alterations associated with sport-related knee injuries may contribute to an unsuccessful return sport or early-onset post-traumatic osteoarthritis. Also, without access sophisticated motion-capture systems, temporospatial monitoring of horizontal hop tests during clinical assessments is limited. By applying alternative measurement system two inertial units (IMUs) per limb, we obtained and validated flying/landing times distances triple single-leg (TSLH) test...
The countermovement vertical jump height, flight time, and duration are used to assess athletic performance. Force-plate motion-capture cameras estimate these parameters, yet, their application is limited dedicated lab environments. Despite the potential of inertial measurement units (IMU) for estimating accuracy has not been validated. This study investigates our proposed method height using a sacrum-mounted IMU, during jumping. Eleven individuals performed four jumps each. To obtain we...
Upper extremity pain and injury are among the most common musculoskeletal complications manual wheelchair users face. Assessing temporal parameters of propulsion, such as propulsion duration, cadence, push recovery is essential for providing a deep insight into mobility, level activity, energy expenditure, cumulative exposure to repetitive tasks thus personalized feedback. The purpose this paper investigate use inertial measurement units (IMUs) estimate these by identifying start end time...
