Capacity is the physiological ability of the neuromusculoskeletal systems; this declines with
age. This decline in capacity may result in the inability to stand up (sit-to-stand, sit-to-walk) …

Recent explorations of knee biomechanics have benefited from computational modeling,
specifically leveraging advancements in finite element analysis and rigid body dynamics of …

For Students: Fundamentals of Biomechanics is written for Kinesiology/Exercise and Sports
Science majors taking the required introductory biomechanics course. Welcome to the …

Background: Anterior cruciate ligament (ACL) injuries are common, and children as young
as 10 years of age exhibit movement patterns associated with an ACL injury risk. Prevention …

Two optimization techniques, static optimization (SO) and computed muscle control (CMC),
are often used in OpenSim to estimate the muscle activations and forces responsible for …

Background Identification of biomechanical risk factors associated with anterior cruciate
ligament (ACL) injury can facilitate injury prevention. The purpose of this study is to …

Beyond qualitative assessment, gait analysis involves the quantitative evaluation of various
parameters such as joint kinematics, spatiotemporal metrics, external forces, and muscle …

Sit-to-stand can be defined as a set of movements that allow humans to rise from a sitting
position to a bipedal standing pose. These movements, often categorized as four distinct …

Background: The purpose of this study was to determine the reliability for the strength and
movement velocity of the concentric phase from the five Sit-to-Stand (5STS), using three …

The latest studies of the 30-second sit-to-stand (30-STS) test aim to describe it by employing
kinematic variables, muscular activity, or fatigue through electromyography (EMG) instead of …
