The neuromuscular efficiency of lower back muscles in low back pain
BACKGROUND: The etiology of low back pain (LBP), one of the most prevalent and costly diseases of our time, is accepted to be multi-causal, placing functional factors in the focus of research. Thereby, pain models suggest a centrally controlled strategy of trunk stiffening in LBP. However, …

Design and Evaluation of a Flexible Exoskeleton for Lifting
… return to its wearer and relieve their lower back muscles. The design of the exoskeleton and potential elastic mechanisms are described, and the results of biomechanical testing are given. The exoskeleton decreased the erector spinae muscle activity by 21-39.7%.

Biomechanical Assessment and Metabolic Evaluation of Passive Lift-Assistive Exoskeletons During Repetitive Lifting Tasks
… due to overexertion and consequently the low back pain (LBP) are one of the most prevalent sources of nonfatal occupational injuries and illnesses in all over the world. In the past several years, the industrial exoskeletons especially the passive ones have been proposed as alternative …

Empirical Evaluation of Models Used to Predict Torso Muscle Recruitment Patterns
For years, the human back has puzzled researchers with the complex behaviors it presents. Principally, the internal forces produced by back muscles have not been determined accurately. Two different approaches have historically been taken to predict muscle forces. The first relies on …

The Neuroscience of Music: An Interdisciplinary Study of the Effects of Music on the Brain
… organs including the entire intestinal tract, back muscles, lungs and heart. It carries the fibers that control the release of gastric and pancreatic secretions, and inhibitory fibers of the heart. This dissertation considers the healing properties of music. It studies the insula, a very …

Loading and recovery behavior of the human lumbar spine under static flexion
… created additional static loading on the lower back. The effects of this task were introduced to the model by adding a third exponential component referred to as the “daily activity” factor. Overall, the results support the previous findings about the behavior of the lower back muscles that were …

Characterizing Human Motor Adaptation and Learning When Using Different Occupational Exoskeletons
… synergy recruitment from primary arm-elevating muscles toward neck and back muscles, reflecting compensatory motor strategies for device-imposed biomechanical demands. Third, adaptation to passive and active back-support exoskeletons was examined during repetitive lifting over four sessions. …

The effects of the lumbopelvic manipulation on the fatigability of the back and hip muscles in adults with chronic low back pain
Patients with chronic low back pain (CLBP) have been shown to have increased fatigability levels of hip and low back muscles as measured by the surface electromyographic (EMG) median frequency (MF). In addition, literature suggests that lumbopelvic manipulation could be an effective intervention …

Endurance of Lower Paraspinals and Gluteal Muscles Using Surface EMG on Healthy Subjects During Performance of Common Lumbar Stabilization Exercises
Low back pain (LBP) has become a major problem in the western world. It is a concern in worker's compensation cases and the reason for many lost work days. In order to effectively rehabilitate persons with LBP, physical therapists need to provide proven methods to improve muscular stability. Lumbar …

Early mobilisation after coronary angiography to reduce back pain
BACKGROUND Coronary heart disease accounts for over 25,000 inpatient admissions and nearly 4,000 day-case admissions in New Zealand per year (Hay, 2004). Cardiac catheterization, via the femoral artery, is a common procedure undertaken to assess for and treat coronary heart disease (Chair, Li and …

Kinematics of the equine axial skeleton during aqua-treadmill exercise
… amplitudes encourages further engagement of back muscles possibly providing stimulus for building greater strength through muscular development.<br/><br/>Water depth was found to have no effect on mediolateral displacements of the pelvis or withers but with the withers exhibiting larger …
