Detection of Knee Insi'abdlity Using Accelerometers
نویسنده
چکیده
Ab." We propose a knee instability detector for standing using two uni-axial accelerometers, tangentially placed on the upper leg. This detector may be used as a part of the finite state artificial reflex control strategy for paraplegic standing with minimal quadriceps stimulation, as proposed by Mulder et al. [l 21. The detection strategy was experimentally tested in two healthy subjects. Detection on the basis of accelerometer data appeared to be faster than with knee goniometer data. Furthermore, accelerometers may be preferable because they are small and do not cross the knee joint, like in the case of conventional goniometers.

Detection of knee unlock during stance by accelerometry.
Detection of knee unlock is a crucial part of finite state artificial reflex control of paraplegic standing supported by functional neuromuscular stimulation (FNS). This paper investigates knee unlock detection schemes using small uniaxial accelerometers mounted on the thigh and shank. Four single and two differential accelerometer configurations were evaluated with respect to knee unlock detec...
متن کاملThe Praxis24 Sensor System for Use in the Closed-Loop Control of Standing
Our aim is to develop a safe and reliable closed-loop sensing system for the implanted FES system (‘Praxis24’, Neopraxis Pty. Ltd., Sydney, Australia), which will be light weight and easy to don/doff. Open-loop FES standing has typically been achieved for 10-20 minutes. This system will be used by paraplegic individuals for prolonged standing (20 minutes +), sitstand-sit transfers and stepping....
متن کاملAssessment of Knee Cartilage Stress Distribution and Deformation Using Motion Capture System and Wearable Sensors for Force Ratio Detection
Knowledge about the knee cartilage deformation ratio as well as the knee cartilage stress distribution is of particular importance in clinical studies due to the fact that these represent some of the basic indicators of cartilage state and that they also provide information about joint cartilage wear so medical doctors can predict when it is necessary to perform surgery on a patient. In this re...

Accelerometer and Gyroscope Based Gait Analysis Using Spectral Analysis of Patients with Osteoarthritis of the Knee
[Purpose] A wide variety of accelerometer tools are used to estimate human movement, but there are no adequate data relating to gait symmetry parameters in the context of knee osteoarthritis. This study's purpose was to evaluate a 3D-kinematic system using body-mounted sensors (gyroscopes and accelerometers) on the trunk and limbs. This is the first study to use spectral analysis for data post ...
