A functional knee brace alters joint torque and power patterns during walking and running.
Individuals with anterior cruciate ligament (ACL) injury use greater extensor torques at the hip and ankle and lower extensor torques and joint power at the knee during gait compared to healthy subjects. These adaptations may be mediated by (1) altered neuromuscular strategies due to the injury, (2) training effects produced by rehabilitation protocols, and (3) training effects due to the funct...
متن کاملUncertainty of knee joint muscle activity during knee joint torque exertion: the significance of controlling adjacent joint torque.
In the single-joint torque exertion task, which has been widely used to control muscle activity, only the relevant joint torque is specified. However, the neglect of the neighboring joint could make the procedure unreliable, considering our previous result that even monoarticular muscle activity level is indefinite without specifying the adjacent joint torque. Here we examined the amount of hip...
متن کاملInfluence of joint angle on EMG-torque model during constant-posture, quasi-constant-torque contractions.
Electromyogram (EMG)-torque modeling is of value to many different application areas, including ergonomics, clinical biomechanics and prosthesis control. One important aspect of EMG-torque modeling is the ability to account for the joint angle influence. This manuscript describes an experimental study which relates the biceps/triceps surface EMG of 12 subjects to elbow torque at seven joint ang...
متن کاملJoint Torque and Mechanical Power of Lower Extremity and Its Relevance to Hamstring Strain during Sprint Running
The aim of this study was to quantify the contributions of lower extremity joint torques and the mechanical power of lower extremity muscle groups to further elucidate the loadings on hamstring and the mechanics of its injury. Eight national-level male sprinters performed maximum-velocity sprint running on a synthetic track. The 3D kinematic data and ground reaction force (GRF) were collected s...
متن کاملEstimation of Joint Torque and Power Consumption During Sit-to-Stand Motion of Human-being Using a Genetic Algorithm
A model of human lower limb along with body has been drawn having a presumed body height and body mass index. Different ranges of joint angles of human legs and body have been taken to simulate the sit-to-stand motion. The kinematic analysis is done by varying joint angles over time. The dynamic studies have been carried out for different joints. Torque and power consumption have been calculate...
