TL;DR: A new method of measuring joint angle using a combination of accelerometers and gyroscopes is presented, which is able to provide joint angles in real-time, and ready for use in gait analysis.

TL;DR: The proposed technique provides a solution to fusing the data of gyroscopes and accelerometers that yields stable and drift-free estimates of segment orientation and is portable, easily mountable, and can be used for long term monitoring without hindrance to natural activities.

TL;DR: It is concluded that it is feasible to estimate movements of thighs from movements of shanks to reduce number of needed sensing units from 4 to 2 in context of ambulatory gait analysis.

TL;DR: An ambulatory system for the three-dimensional (3D) knee kinematics evaluation, which can be used outside a laboratory during long-term monitoring, was developed and knee function was analysed using this system, after an anterior cruciate ligament (ACL) lesion, and after reconstructive surgery.

TL;DR: The results showed that knee replacement and rehabilitation programs improved the coordination score, and the technique provides an analytical tool that can be used as a routine test in the clinical evaluation of human gait abnormalities.
