MECHANICALLY ROBUST BIOCOMPATIBLE POLYMERIC NETWORKS FOR REPETITIVE LOADING
… applications that demand high resilience under repetitive load-bearing conditions. However, conventional hydrogels often exhibit poor mechanical strength and irreversible damage under cyclic deformation, while traditional dental resins lack strong bonding to mineralized tissues and suffer from …

SEX DIFFERENCES IN HEAD IMPACT BIOMECHANICS AND QUANTITATIVE FUNCTIONAL DEFICITS DUE TO REPETITIVE LOADING IN HIGH SCHOOL SPORTS
… for the neurological outcomes associated with repetitive head loading in contact sports. In this dissertation, the effects of repeated head loading were investigated in adolescent male and female athletes through four research aims. Sensor error (i.e., intrinsic error, coupling error, and false …

Intrinsic and extrinsic factors associated with change in range of motion (ROM) after a single stretch session and repeated loading following an endurance run
… to static stretching. Furthermore, prolonged repetitive loading has also been shown to affect ROM of a joint or series of joints. In particular, runners have a significantly decreased hamstring ROM. The aim of this study was to investigate the factors which are associated with a change in ROM …

Computational study of compact tension and double torsion test geometries
… engineering components subjected to cyclic or repetitive loading,fatigue is an ever-present challenge. The engineer often endeavors to design the structural or component system in such a way that the cyclic stresses are below a particular fatigue limit, or, in fracture mechanics terms, at …

Methodology to predict the strength and stiffness of red alder block pallet connections fastened with helically threaded nails
… rubra) nailed pallet connections subjected to repetitive loading. Joint tests were conducted to define the mechanical properties of bottom block pallet connections. The primary tests were conducted to define the strength and stiffness of joint specimens tested in cyclic lateral loading, using …

Peak pressure under the forefoot in classical ballet
… Chronic and acute injuries relate primarily to repetitive loading of the foot and ankle during pointe work, which forms the basis of the technique in classical ballet. This study determined the differences in the peak pressure distributed under the forefoot in flat foot and in pointe position. …

A Comparison of Methods for Measuring Damage in Sucrose-Treated Medial Collateral Ligaments
… of muscle, bone, and ligaments that endures repetitive loading during daily and athletic activities. When this loading is excessive, damage to the knee occurs leading to a decreased quality of life.The medial collateral ligament (MCL) is one of the 4 major ligaments known to be commonly …

Long-term response of soils subjected to repetitive geoenvironmental loads
Repetitive loading cycles originate from a variety of natural and industrial processes, affect soil properties and the long-term performance of geotechnical systems. This thesis provides unprecedented experimental data and physical analyses of repetitive environmental loading cycles on …

Mechanical loading and cartilage physiology
… it has been noted that altered joint loading and increased force may lead to cartilage degradation and increase the risk for the development of osteoarthritis (OA). This study investigated the cellular responses of chondrocytes to mechanical impact, and the effects of possible …

Multiscale modeling of the lumbar spine to investigate tissue-level load transfer during activities of daily living
… subpopulations who experience more extreme repetitive spine kinematics is often attributed to biomechanical factors. Repetitive loading of the spine during lumbar movements produces damage in innervated elements known to be sources of pain, with examples including: vertebral body fractures, …

Quantitative Texture and Blob Analyses on Patellar Tendon Sonographic Images of Collegiate Basketball Athletes
… "Jumper's Knee", is a condition resulting from repetitive loading of the patellar tendon that presents as anterior knee pain, which is commonly seen in basketball players due to the maneuvers in the sport. Diagnosis of PT often involves a clinical exam followed by ultrasound images for …

Trunk loading and back pain
… stability. Stabilising the trunk during sudden, repetitive loading in everyday tasks, as well as during performance is important in order to protect against injury. Hence, reduced trunk stability is accepted as a risk factor for the development of back pain (BP). An altered activity pattern …

The effect of an exercise intervention on peripheral sensorimotor function in neuropathic diabetics
… risk of plantar ulceration due to traumatic or repetitive loading. The evidence for the effectiveness of an exercise intervention in improving sensorimotor function in this population is building, but care is needed when implementing these interventions due to the risk of exacerbating associated …
