The goal of this chapter is to demonstrate the role of integrated biomechanical analyses in complex movements such as gait in alerting researchers of the goals and synergies of the CNS. Because of the large number of segments involved and the potential for the CNS to take advantage of inter-limb coupling it is only through appropriate biomechanical analyses that such collaboration can be identi...

People grasp objects differently depending on what they plan to do with the objects. One hypothesis concerning this tendency is based on the end-state comfort effect, which has been described as a tendency to grasp an object in an uncomfortable way that allows for a more comfortable final posture [1]. Following up on this hypothesis, we sought to introduce quantitative indices of “comfort” base...

Corneal hysteresis (CH) is a parameter which measures the viscoelastic behaviour of the cornea, indicating its biomechanical integrity1. Some clinical conditions such as keratoconus, Fuchs corneal dystrophy, high myopia, glaucoma and corneal refractive surgery, may induce changes in corneal biomechanical properties, leading to a decrease in CH2-6. Astigmatism, a refractive error related to corn...

Understanding of tibiofemoral joint mechanics at multiple spatial scales is essential for developing effective preventive measures and treatments for both pathology and injury management. Currently, there is a distinct lack of specimen-specific biomechanical data at multiple spatial scales, e.g., joint, tissue, and cell scales. Comprehensive multiscale data may improve the understanding of the ...

OBJECTIVE Develop a gender specific database of trunk muscle cross-sectional areas across multiple levels of the thoracic and lumbar spine and develop prediction equations for the physiological cross-sectional area as a function of gender and anthropometry. DESIGN This study quantified trunk muscle cross-sectional areas of male and female spine loading muscles. BACKGROUND There is a lack of...

The Yoga Empowers Seniors Study (YESS) was an intervention development study (IDS) that used biomechanical investigation (high-speed cameras, force platforms, and musculoskeletal modeling) to quantify the physical demands of yoga performance by older adults. Secondarily, the YESS used physical-performance testing, muscle-performance testing , and flexibility and balance assessments to quantify ...

The internal brace technique uses a high-strength suture tie to augment injured tissues or a primary repair, allowing early rehabilitation. Anatomic repair with internal bracing is a novel and promising treatment for femoral-sided medial knee avulsion injuries of the medial collateral ligament and posterior oblique ligament. Unfortunately, biomechanical and clinical data are lacking. To evaluat...

background patients who have shoulder pain usually have compensatory or contributory deviation of shoulder motion during arm elevation. in the traditional scapulohumeral rhythm, the share of the acromioclavicular (ac) and the sternoclavicular (sc) joint movements and also the role of ac internal rotation angle are unknown. objectives the main purpose of this study was to measure and compare the...
