A knee brace design to reduce the energy consumption of walking
… strike. One simulation goal was to explore the knee spring properties which enable lossless walking. Simulations show that there are two knee spring configurations which allow for lossless walking. It is also shown that the percentage of kinetic energy transferred to a knee spring can be a …

IMU-Integrated 'Smart' Knee Brace Validation Using Optoelectronic Motion Capture During Treadmill Walking
… to be valid in measuring joint angles. A ‘smart’ brace was implemented with two IMUs and the knee joint angles calculated using data from the ’smart’ brace were compared to a gold standard motion capture system to assess the agreement and reliability of the brace. Ten participants visited the lab …

Design and evaluation of a quasi-passive robotic knee brace : on the effects of parallel elasticity on human running
… addition of an external elastic element at the knee during the stance phase of running results in a reduction in knee extensor activation so that total joint quasi-stiffness is maintained. To test this, an exoskeleton is presented, consisting of a leaf spring in parallel with the knee joint and …

Exploring the Effects of a Non-mechanical Knee Brace on Lower Limb Kinematics & Kinetics in Healthy Individuals & its Implications for Patients with Osteoarthritis of the Knee
Background: Knee orthoses for osteoarthritis represent a possible treatment for patients not suited for surgery. Although effective biomechanically, mechanical braces can be unattractive to patients. Controlling symptomology by altering neuromuscular control with the use of non-mechanical …

Mechanical bracing solutions to decrease tibial slippage of Anklebot
… in the separation between markers on the knee brace and leg was used as a measure of slippage. The exoskeleton did not decrease slippage primarily due to high tolerances in the inversion-eversion joint at the heel of the shoe. The waist support system decreases slippage when enough bungees …

The effect of prophylactic knee braces on running gait
The use of prophylactic knee braces to prevent knee injuries in football players might increase the risk of injuries to the players because of changes in normal function. This study focused on one of seven criteria for knee braces developed by the American Academy of Orthopedic Surgeons, namely …

Evaluation of variables affecting lower extremity alignment in the aetiology of patellofemoral pain syndrome
… patellofemoral pain syndrome (PFPS) is a common knee disorder in a wide range of physically active individuals which, in general, is caused by multiple risk factors affecting the alignment of the patellofemoral joint. The role of many presumed risk factors in the aetiology of PFPS remains however …

A systematic review: The effect of prophylactic braces on reducing risk factors related to ACL injury in athletes
… study sought to review research on prophylactic knee bracing (PKB) for the reduction of the risk factors related to injury of the ACL.</p> <p><strong>Methods: </strong>An extensive search of articles from 1990-2021 was performed with inclusion criteria of no previous ACL injury, no knee injury or …

The Effects of Wearing Prophylatic Knee Sleeves/Braces on Selected Isokinetic Measures During a Velocity Spectrum Knee Extension Test
… to examine the effects of wearing prophylatic knee sleeves/ braces on selected isokinetic measures (i.e. strength, power and endurance). Each subject performed the Biodex (Multi-Joint System 2AP) knee extension test in each of three experimental conditions: sleeved with the Don Joy Knee support …

Towards an algorithm for the prediction of non-contact anterior cruciate ligament injuries
… The anterior cruciate ligament (ACL) of the knee is one of the most frequently injured ligaments in the body. 70% of ACL injuries are sustained without any direct contact to the knee, during the early stance phase of a rapid deceleration movement. Females have a significantly greater risk of …

The application of prophylactic knee bracing in relation to selected proprioceptive and fitness and skill parameters in first league South African rugby players
… contact, there has been a high incidence of knee injuries in match situations as well as in training sessions. Ample literature is available on the effect of braces for the prevention and recurrence of injuries. However, due to different research fields/subjects (American football, soccer and …
