The purpose of this study was to examine the frequency of co-contraction and the relationship between reflex activity and co-contraction during passive movements of the knee joint in children with cerebral palsy. Methods Twenty children with cerebral palsy participated in this study. One set of ...
The knee is known as a synovial hinge joint. Two or more bones are required to create a hinge joint and it results in one axis on which the joint can flex or extend. Dislocations of the knee can result in loss of a few or all of the four types of movements it can perform.Answer ...
Anatomical structures: The tibia of the leg moves relative to the femur of the thigh. Reference axes: The movement is in the sagittal plane. The fulcrum is provided by the knee joint, through which the frontal/coronal axis passes. Direction: During flexion, the leg moves backwards (posteriorly...
Results are presented for four joints (shoulder, elbow, hip and knee) with emphasis on the shoulder, and for five types of locomotion (catarhine primate quadrupedal walking, human hands-and-feet creeping and hands-and-knees creeping, and human walking and running). Fourier analysis facilitates ...
For this reason, we developed a novel test device to simulate the rolling-sliding-movements of the knee joint. Thereby, new materials can be analysed ... P Goebel,C Zietz,R Bieck,... - 《Biomedical Engineering》 被引量: 1发表: 2012年 Non-linear dynamics and stability of rolling bearing...

Excessive repetitive impacts in human walking lead to lower extremity orthopaedic disorders such as degenerative joint disease and prosthetic loosening. In this study, two planar models, corresponding to free or fixed ankle joints, were used to examine movements of the knee and ankle joints that affe...
The sense of position and movement in the knee joint during voluntary movements. The aim of the paper was to assess body position reproduction as well as jump height during an intended movement, together with an assessment of the influe... Dagmara Iwańska,Czesaw Urbanik - 《Acta of Bioengin...
While variations of the leg curl are ideal when seeking to isolate the hamstrings (by working the muscles from the knee joint), the Romanian Deadlift hits the hams from the hips, thus providing top to bottom mass that might otherwise be neglected with the curls.6, 7Great hamstrings are esse...
Pivoting sports expose athletes to a high risk of knee injuries, mainly due to mechanical overloading of the joint which shatters overall tissue integrity. The present study explored the magnitude of tibiofemoral contact forces (TFCF) in high-risk dynamic tasks. A novel musculoskeletal model with...
