BACKGROUND Low back pain is a highly prevalent condition in the United States and has a staggeringly negative impact on society in terms of expenses and disability. It has previously been suggested that rehabilitation strategies for persons with recurrent low back pain should be directed to the medial back muscles as these muscles provide functional support of the lumbar region. However, many i...
Endurance of trunk muscles in persons with chronic low back pain: assessment, performance, training.
Trunk muscles are designed to fulfill their role of continuous activity throughout the day, but pain and inactivity alter muscles so that they fatigue in normal situations. Lack of endurance of the trunk muscles is an important factor in low back pain (LBP). This paper examines some methods to objectively test endurance of trunk flexor and extensor muscles in static and dynamic situations, and ...
Working at a computer is part of a large number of jobs and has been associated with upper extremity musculoskeletal disorders and back pain. The study evaluated the effects of a board attachment on upper extremity and back. The findings are mixed in that the board may have a positive effect in preventing back pain, but may be detrimental to upper extremities. Effect of a desk attachment board ...
background: alterations in the neuromuscular control of the spine were found in patients with chronic low back pain (clbp). sudden loading of the spine is assumed to be the cause of approximately 12% of lower back injuries. however, some aspects of this problem, such as alterations in the sensory–motor control of the spine, remain questionable. this study investigated postural and neuro–motor c...
Aims and background: Low back pain is one of the most common musculoskeletal disorders leading to disability in the world. Several studies have shown that long-term sitting is associated with low back pain and discomfort. The weakness of core stability is referred to as one of the factors associated with the low back pain. So the purpose of this study was the study of relationship between core...
In this investigation we have estimated the afferent contribution to the generation of activity in the knee and ankle extensor muscles during walking in decerebrate cats by loading and unloading extensor muscles, and by unilateral deafferentation of a hind leg. The total contribution of afferent feedback to extensor burst generation was estimated by allowing one hind leg to step into a hole in ...
Objectives: Prone hip extension (PHE) is a commonly used test to investigate the extensor activation pattern in the lumbo-pelvic area. It has been belived that performing abdominal stabilization maneuvers during PHE may change the pattern of lumbo-pelvic muscles activity. No study has yet assessed the muscular activation pattern during PHE with and without abdominal bracing (AB) to activate all...
