Download or read book Impact of Neck Muscle Fatigue on Upper Limb Sensorimotor Integration written by Mahboobeh Zabihhosseinian and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neck muscles have a high density of sensory receptors which project to the central nervous system, and have important role in sensory motor integration (SMI). The cerebellum is important for SMI and it is known to undergo neuroplastic changes in response to performing a novel motor acquisition task. Alterations in neck sensory input impacts motor output to upper limb muscles, cerebellar disinhibition, and performance accuracy in response to novel motor acquisition. Despite this, the impact of cervical extensor muscle (CEM) fatigue on cerebellar-motor cortex plasticity and SMI pathways in response to a novel motor acquisition task has not been yet investigated. Study one used short latency somatosensory evoked potentials (SEPs) to investigate the differential effects of CEM fatigue on motor learning and retention; and on sensorimotor processing from distal hand muscles. CEM fatigue impaired upper limb motor learning performance in conjunction with differential changes in SEP peak amplitudes related to SMI. Study two used a paired pulse cerebellar-motor cortex transcranial magnetic stimulation (TMS) technique to determine whether CEM fatigue alters cerebellar disinhibition in response to novel motor skill acquisition. Neck fatigue led to a lessened capacity for cerebellar disinhibition coupled with diminished motor learning relative to a control group. Study three used an eye-hand tracking protocol to investigate the effect of CEM fatigue on accuracy of pointing to both visual and hidden targets. CEM fatigue reduced the accuracy of upper limb tracking to a hidden target. Study four used short- and medium-latency SEPs to determine the impact of CEM fatigue on motor performance accuracy and retention of proximal upper limb muscles, as well as neural processing changes in response to novel motor acquisition using proximal upper limbs muscles. CEM fatigue had minimal impact on proximal upper-limb motor performance accuracy, but lead to differential changes in both short- and medium- latency SEP peak amplitudes related to SMI. Overall, this thesis suggesting that SMI areas including the cerebellum are impacted by CEM fatigue, likely because the altered afferent input from the neck due to fatigue alters body schema, impacting awareness of upper limb position sense, resulting in decreased upper limb performance accuracy.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neck and upper limb disorders constitute two of the most frequent musculoskeletal problems that place a huge burden on the healthcare system. Neck muscles have a very high density of muscle sensory input to the central nervous system (CNS) and are known to play an important role in sensory motor integration of upper limb movements. The CNS uses the position of the head and neck in interpretation of upper limb joint position sense (JPS). Therefore, any altered neuromuscular function of the cervical extensors has the potential to impair the awareness of upper limb joint position which is critical for carrying out smooth, purposeful movements. Despite this, only a small amount of basic science research has attempted to explore the relationship between altered afferent input from the neck on both neck and upper limb neuromuscular control. Additionally, the cervical flexion relaxation ratio (FRR) is a reliable and reproducible neuromuscular marker, which has been shown to differentiate between neck pain patients and healthy controls, and presents an objective way to measure changes in neuromuscular function. Induction of fatigue provides an experimental method for altering afferent input from the neck muscles to the CNS, enabling the effects of both neck muscle function and upper limb JPS to be investigated in an experimental setting. Studies in this thesis sought to investigate whether the elbow JPS and neck FRR can be altered by fatigue of the cervical extensor muscles (CEM). This study revealed that CEM fatigue decreased the cervical FRR, by increasing the EMG activity in relaxation phase, and reduced the accuracy of elbow joint position matching in healthy individuals. Whereas, slightly expanded the FRR in subclinical neck pain patients, by increasing the EMG activity in re-extension phase. This work has important implications for our understanding of the mechanisms that the CNS uses to stabilize the neck in the face of altered afferent input, and the implications that this may have for upper limb proprioception and associated motor performance.
Download or read book The Effect of Neck Muscle Fatigue on Shoulder Humeral Rotation Proprioception written by Matthew S. Russell and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of the cervical extensor muscles (CEM) is thought to disrupt afferent feedback from postural mechanoreceptors as it has been observed to cause decrements in upper limb proprioceptive accuracy. There has been limited research to quantify this interaction at the shoulder; thus further investigation into the effect of neck fatigue on shoulder joint position sense (JPS) accuracy is necessary. In this thesis, study one determined that high variability in upper limb DOFs led to no effect of neck fatigue on humeral rotation proprioception. Study two identified wrist deviation as a significant contributor to end effector variability when performing unconstrained humeral rotation. Wrist deviation will require a sufficient method of constraint in order to make significant observations of end effector position during humeral rotation possible.

Download or read book Musculoskeletal Disorders and the Workplace written by Institute of Medicine and published by National Academies Press. This book was released on 2001-05-24 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.

Download or read book Multiple Sclerosis written by Institute of Medicine and published by National Academies Press. This book was released on 2001-08-10 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple sclerosis is a chronic and often disabling disease of the nervous system, affecting about 1 million people worldwide. Even though it has been known for over a hundred years, no cause or cure has yet been discovered-but now there is hope. New therapies have been shown to slow the disease progress in some patients, and the pace of discoveries about the cellular machinery of the brain and spinal cord has accelerated. This book presents a comprehensive overview of multiple sclerosis today, as researchers seek to understand its processes, develop therapies that will slow or halt the disease and perhaps repair damage, offer relief for specific symptoms, and improve the abilities of MS patients to function in their daily lives. The panel reviews existing knowledge and identifies key research questions, focusing on: Research strategies that have the greatest potential to understand the biological mechanisms of recovery and to translate findings into specific strategies for therapy. How people adapt to MS and the research needed to improve the lives of people with MS. Management of disease symptoms (cognitive impairment, depression, spasticity, vision problems, and others). The committee also discusses ways to build and financially support the MS research enterprise, including a look at challenges inherent in designing clinical trials. This book will be important to MS researchers, research funders, health care advocates for MS research and treatment, and interested patients and their families.

This book was released on 2017-09-01 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Census Bureau has reported that 56.7 million Americans had some type of disability in 2010, which represents 18.7 percent of the civilian noninstitutionalized population included in the 2010 Survey of Income and Program Participation. The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. As of December 2015, approximately 11 million individuals were SSDI beneficiaries, and about 8 million were SSI beneficiaries. SSA currently considers assistive devices in the nonmedical and medical areas of its program guidelines. During determinations of substantial gainful activity and income eligibility for SSI benefits, the reasonable cost of items, devices, or services applicants need to enable them to work with their impairment is subtracted from eligible earnings, even if those items or services are used for activities of daily living in addition to work. In addition, SSA considers assistive devices in its medical disability determination process and assessment of work capacity. The Promise of Assistive Technology to Enhance Activity and Work Participation provides an analysis of selected assistive products and technologies, including wheeled and seated mobility devices, upper-extremity prostheses, and products and technologies selected by the committee that pertain to hearing and to communication and speech in adults.
