Coronal Plane Measurement Of Patella Tracking Following Knee Replacement: A Novel Use Of Ultrasound and Motion Capture

بررسی مسیر حرکتی استخوان کشکک در زوایای متوالی دامنه حرکتی زانو در بیماران مبتلا به جابجایی خارجی استخوان کشکک و افراد سالم

Background: Patellofemoral joint disorders are the most common cause of anterior knee pain in patients who referred to orthopedic clinics. Patellar lateralization cause anterior knee pain due to weakness of vastus medialis oblique muscle or tightness of lateral structures like lateral retinaculum or iliotibial band muscle. Materials and Methods: For evaluation of this abnormality, plane radiog...

OPEN PATELLA PERIPROSTHETIC FRACTURE AFTER TOTAL KNEE REPLACEMENT: A CASE REPORT AND REVIEW OF LITERATURES

A Real-time Motion Tracking Wireless System for Upper Limb Exosuit Based on Inertial Measurement Units and Flex Sensors (TECHNICAL NOTE)

This paper puts forward a real-time angular tracking (motion capture) system for a low cost upper limb exosuit based on sensor fusion; which is integrated by an elastic sleeve-mitten, two inertial measurement units (IMU), two flex sensors and a wireless communication system. The device can accurately detect the angular position of the shoulder (flexion-extension, abduction-adduction and interna...

An Implantable System for Angles Measurement in Prosthetic Knee

In this work we designed and tested an in-vivo measurement system of prosthetic knee joint angles. The system included a small permanent magnet in the femoral part and three magneto resistance sensors placed in the polyethylene part. The sensor configuration was defined based on sensitivity analysis, signal to noise ratio, saturation of sensors and movements constraints. A mapping algorithm was...

Early Regain of Function and Proprioceptive Improvement Following Knee Arthroplasty

Background: Techniques that allow early muscle activation, such as closed kinetic chain (CKC) and open kineticchain (OKC) exercises, may play a beneficial role in the early rehabilitation of the reconstructed knee. However,current rehabilitation regimens have not been shown to reverse post-operative quadriceps activation failureand weakness. To investigate whether patients who use a continuous ...
