Prior to the introduction of the C3D file format almost all biomechanics and gait analysis software was written for each specific 3D system manufacturers file format. As a result, researchers and clinicians were restricted to either writing their own analysis software or else using only the software provided by with their 3D data collection system.
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
X-ray motion analysis is a technique used to track the movement of objects using X-rays.This is done by placing the subject to be imaged in the center of the X-ray beam and recording the motion using an image intensifier and a high-speed camera, allowing for high quality videos sampled many times per second.
In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body(ies).
Knee pain is pain in or around the knee. The knee joint consists of an articulation between four bones: the femur , tibia , fibula and patella . There are four compartments to the knee.
Poor lower extremity biomechanics may cause stress on the knees and can be related to the development of patellofemoral pain syndrome, although the exact mechanism linking joint loading to the development of the condition is not clear. Foot orthoses can help to improve lower extremity biomechanics and may be used as a component of overall ...
Taking a knee: where the upper body is vertical, one knee is touching the ground while the foot of the other leg is placed on the ground in front of the body Lying [ edit ]
Complaints of locking sensation in the knee joint can be divided into true locking and pseudo locking. True locking happens when the intra-articular structure (e.g. ligaments) [1] is damaged, or a loose body is present inside the joint, or there is a meniscal tear. The knee can be unlocked by rotating the leg and full movement can be restored.
