Book Synopsis Working Postures and Movements by : Nico J. Delleman
Download or read book Working Postures and Movements written by Nico J. Delleman and published by CRC Press. This book was released on 2004-06-29 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most industries, musculoskeletal injuries are the most common work-related reason for employee absences. These injuries are often caused by static postures or repetitive movements that have to be maintained for many hours a day, such as intensive use of data entry devices, assembly work, parts inspection, equipment maintenance, manual materials handling, machinery operations, and vehicle operation, among others. In order to prevent such injuries, occupational health professionals, ergonomists, production engineers, and product designers need to know how to evaluate postures and movements, and understand how these are determined by the work environment, as well as what design tools are available to achieve less stressful working postures and movements.Working Postures and Movements describes many internationally accepted evaluation tools applicable to postures and movements in the work environment. Renowned researchers from around the world have brought together the latest scientific knowledge describing the anthropometry, biomechanics, physiology, psychophysics, and human perceptual-motor control basis for posture and movement assessment related to all the major body segments. The book addresses seating concepts, hand tool and pedal designs, foot-floor interfaces, digital human models for computer-aided design and engineering, and work organization (task duration, breaks, handling frequency) as they affect human performance and musculoskeletal injury reduction. Professionals responsible for identifying and improving conditions in the industries where such workplace injuries occur will find this volume to be a handy sourcebook, while teachers and students will find it to be a valuable reference.

Book Synopsis Musculoskeletal Disorders and the Workplace by : Institute of Medicine
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.

Book Synopsis Investigation of Postures and Prevalence of Musculoskeletal Disorders by : Taiwo Samuel
Download or read book Investigation of Postures and Prevalence of Musculoskeletal Disorders written by Taiwo Samuel and published by LAP Lambert Academic Publishing. This book was released on 2011-10 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing gari-frying methods (ITGMs) remain largely manual, with low productivity and health hazards. Awkward posture, a risk factor for musculoskeletal disorders (MSDs) in these methods, has huge cost implications, but preventable with simple, inexpensive modifications to work methods. The common working postures with their physical workload and postural angle associated with them include sitting-beside SB, sitting-in-front SIF, standing S and alternating-between-sitting-and-standing ABSS. Prevalence of MSDs was determined using Rapid Upper Limb Assessment, Ovako working Posture Analyzing System and Cornell Musculoskeletal Discomfort Questionnaire. Results showed that posture has significant effects on the prevalence of MSDs, though gari frying is a light task. Specific discomforts in the body were detailed and highest in the trunk. Risk factors include repetition, static work and contact stress. S posture ranked highest in MSD risks, ABSS the lowest; hence the preferred posture. A new ITGM has evolved to widen and diversify small-scale rural and informal women's income-earning opportunities. Appropriate technology of this kind, adopting ABSS, is recommended in similar activities.
Book Synopsis Postural Instabilities and the Maintenance of Bi-manual Rhythmic Movement by : Avelino Amado
Download or read book Postural Instabilities and the Maintenance of Bi-manual Rhythmic Movement written by Avelino Amado and published by . This book was released on 2014 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most research on bimanual rhythmic coordination has occurred with the participants in a seated posture. Many activities of daily living, however, require the interaction of standing postural and manual tasks. A population of individuals that are ideal for studying the integration of a manual task into the ongoing control of posture are expert marching percussionists; they have learned to produce rhythmic movements accurately under a variety of temporal and postural constraints. The purpose of the current study was to investigate the integration of bimanual rhythmic movements and posture in expert marching percussionists. Participants (N=11) were recruited from the University of Massachusetts Drumline, and were asked to perform three rhythmic tasks [1:1, 2:3, and 2:3-F (2:3 rhythm played faster at a self-selected tempo)] in one of three postures: sitting, standing on one foot, and standing on two feet. Discrete relative phase, postural time-to-contact, and coherence analysis, were used to analyze the performance of the manual task, postural control, and the integration between postural and manual performance. Across all three rhythms, discrete relative phase mean and variability (SD) results showed no effects of posture on rhythmic performance. The complexity of the manual task (1:1 vs 2:3) had no effect on postural time-to-contact. However, increasing the tempo of the manual task (2:3 vs. 2:3=F) did result in a decreased postural time-to-contact in the two-footed posture). Coherence analysis revealed that the coupling between the postural and manual task significantly decreased as a function of posture (going from a two footed to a one footed posture) and rhythmic complexity (1:1 vs. 2:3). Taken together, these results demonstrate that expert marching percussionists systematically decouple postural and manual fluctuations in order to preserve the performance of the rhythmic movement task.

Book Synopsis Quantification of Upper Extremity Physical Exposures of Materials Handling Tasks in Seated and Standing Configurations by : Alan Christian Cudlip
Download or read book Quantification of Upper Extremity Physical Exposures of Materials Handling Tasks in Seated and Standing Configurations written by Alan Christian Cudlip and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Prolonged periods in sitting or standing may negatively influence worker health. Integration of sit-stand workstations has attempted to mitigate these deleterious effects, and has generated positive results in terms of postural discomfort, injury risk and worker fatigue. Identification of how identical tasks are affected by sitting and standing is necessary to take advantage of loading differences between these configurations. The purpose of this research was to determine if differences in workplace configurations between seated and standing postures created changes in posture or muscular activity levels during manual materials handling tasks. Twenty male and twenty female participants performed four manual materials handling tasks: a 40N static push, a 40N static pull, a weighted bottle transfer set at 15% of the participant's maximal arm elevation force, and a light assembly task in sitting and standing. Upper extremity electromyography was collected at 8 sites, and changes in local joint moments and body discomfort were calculated. Interactions between task and sit/stand configuration resulted in increases of up to 500% in some joint moments, 94% in EMG activity and 880% in some local body discomfort regions when tasks were completed in sitting. A main effect of sitting appeared primarily in joint moments and muscle activity, and generally resulted in increased loading in sitting. Important exceptions existed, which included resultant wrist joint loading 8.2 times larger in standing, and foot/shank discomfort increasing by up to 609%. Task differentially affected all EMG outputs, as well as most local joint moments and body discomfort regions. Future recommendations regarding upper extremity exposures during manual materials handling tasks should consider placing workers in standing postures instead of seated ones to minimize musculoskeletal loading to the upper extremity. In addition, the effects of task and sit/stand configuration should be considered in order to leverage differences between these positions, with tasks in standing generally resulting in decreased musculoskeletal disorder risks.

Available in PDF, EPUB and Kindle. Book excerpt: A manual for understanding the anatomical and emotional components of posture in order to heal chronic pain • Contains self-help exercises and ergonomics information to help correct unhealthy movement patterns • Teaches how to adopt suitable posture in the modern sedentary world Many people cause their own back and body pain through their everyday bad postural and movement habits. Many sense that their poor posture is probably the root of the problem, but they are unable to change long-standing habits. In The New Rules of Posture, Mary Bond approaches postural changes from the inside out. She explains that healthy posture comes from a new sense we can learn to feel, not by training our muscles into an ideal shape. Drawing from 35 years of helping people improve their bodies, she shows how habitual movement patterns and emotional factors lead to unhealthy posture. She contends that posture is the physical action we take to orient ourselves in relation to situations, emotions, and people; in order to improve our posture, we need to examine both our physical postural traits and the self-expression that underlies the way we sit, stand, and move. The way we walk, she says, is our body’s signature. Bond identifies the key anatomical features that impact alignment, particularly in light of our modern sedentary lives, and proposes six zones that help create postural changes: the pelvic floor, the breathing muscles, the abdomen, the hands, the feet, and the head. She offers self-help exercises that enable healthy function in each zone as well as information on basic ergonomics and case histories to inspire us to think about our own habitual movements. This book is a resource for Pilates, yoga, and dance instructors as well as healthcare professionals in educating people about postural self-care so they can relieve chronic pain and enjoy all life activities with greater ease.

Download or read book Working Posture Assessment written by Daniela Colombini and published by CRC Press. This book was released on 2018-09-03 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers how to analyze awkward working postures, particularly of the spine and lower limbs, in specific groups exposed. The methods covered suggests how to evaluate the postures correctly, taking account of the duration and sequence of the tasks involved, even in very complex scenarios where workers are involved with multiple tasks and work cycles varying from day to day. Excel spreadsheets located on the authors’ website (www.epmresearch.org) have been developed to gather, condense, and automatically process the data. The tools serve to implement the strategy for calculating risk associated with exposure to awkward postures, i.e. the TACOS method. Included are 5 case studies which include physiotherapists, workers from construction, archaeological digs, vineyards, and kindergarten teachers. Features Provides a coherent definition of what the study of awkward postures is Clarifies and explains which parameters need to be detected and analyzed for the study of the working postures Defines the phases of a proper organizational study (e.g. tasks, postures, duration, and how often the postures will last) in the working cycle Presents a new and original risk calculation model for awkward postures, with particular attention to the study of the spine and the lower limbs Offers a free excel spreadsheet located on the authors' website which implements the strategy for calculating risk associated with exposure to awkward postures

Available in PDF, EPUB and Kindle. Book excerpt: Remember the last time your back or neck was in pain? I'm pretty sure that you don't want this to happen again... THE POSTURE MANUAL's simplified yet pedagogic approach is designed to empower you, so that you don't ever need a therapist to help you fix your posture again! I know what you're thinking: "I have heard this all before, stand up straight, bend your knees to lift, etc." Give me a few minutes, and soon you will realize why most of the advice you very commonly hear actually damages your body. I have been there too, and I know how difficult and expensive it can seem at first... BUT once we realize that most of our aches and pains are cumulatively exacerbated through our habits, the solution becomes clear. Improving our behavior, correcting our posture and, as far as realistically possible, changing our environment become the key variables for fixing our health. Since 2004, the thousands of people that I have advised have in turn helped me design a universal, powerful and didactic framework called the 3 Rules of Posture. They will make biomechanics simple, enjoyable and universal: they apply to us all, whether at work, home and even while at your hobbies. Let me bring you back to the fundamentals of posture and body awareness, and soon you will need neither a monthly chiropractor visit nor any expensive gadgets.
Book Synopsis The Impact of a Change in Work Posture on Work-related Musculoskeletal Disorders Among Sewing-machine Operators, Managed Within a Physiotherapy and Ergonomics Programme by : Susanna Helena Grobler
Download or read book The Impact of a Change in Work Posture on Work-related Musculoskeletal Disorders Among Sewing-machine Operators, Managed Within a Physiotherapy and Ergonomics Programme written by Susanna Helena Grobler and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: When implementing a managed healthcare intervention among a working population, evidence-based healthcare is critical. In the current study, the change of work posture of sewing-machine operators from seated to stand-up (the intervention) was managed within a physiotherapy and ergonomics programme (programme) in Johnson Controls Automotive S.A. (Pty) Ltd (company) without local evidence to guide the postural transition. The management of the intervention, implemented over a period of 4.5 years, presented the opportunity for a retrospective longitudinal study. The study determined the impact of the change in work posture on the incidence of work-related musculoskeletal disorders (WRMSDs) from June 2004 to January 2009 (period). The role of the physiotherapist in the programme was to deliver manual therapy to all sewing-machine operators with WRMSDs, and to provide a clinical - ergonomics service, as a member of a multidisciplinary team, to the company. The population of sewing-machine operators (n=123) was described in terms of personal factors (e.g. age, medical history, musculoskeletal history, and body mass index (BMI)), ergonomic risk factors (e.g. work posture, force and duration) and overall incidence of WRMSDs. The associations of risk factors (personal and ergonomic) with WRMSDs, and work posture with WRMSDs among sewing-machine operators were statistically determined. The majority of the population (97.6%) was female, with mean age 42.3 8 years. At baseline, 17.9% were hypertensive, 3.3% had arthritis, 6.5% were diabetic, and the mean BMI was 29.7 kg/m? (22% of BMIs was normal). The largest proportion of the sewing-machine operators were sewing cloth and leather (79.7%) (compared to sewing cloth and vinyl), and the remainder performed forceful precision stitching (20.3%), including headrest covers, airbags and top stitching on the final product. Job rotation took place between forceful precision stitching and straight stitching (for 36.6% of the sewing-machine operators).p> The intervention was implemented within the study period. At baseline 100% of sewing machine operators were sewing in the seated work posture. Early in the study, 17.9% of them changed their work posture from seated to stand-up, 30.1% changed to the stand-up work posture in January 2007, and 34.9% a year later. The last 17.1% remained seated till the last year of the study period. From July 2008, 100% of the sewing-machine operators were sewing in the stand-up work posture. The results indicated two strong associations of risk factors and a change in work posture with WRMSDs. Obesity (specifically morbid obesity) was a personal risk factor for upper limb disorders and working in the stand-up work posture was protective for spinal disorders, compared to working in the seated work posture. Furthermore, the results indicated a high incidence of disorders (specifically of the spinal area and upper limb) during the first three months of the programme, as well as an increased incidence of lower leg disorders for the first and consecutive month of the change in work posture from seated to standing up. Lower limb disorders were specifically associated with obesity. The increase of lower limb disorders during the postural adaptation phase was temporary, and was addressed within the programme with proper shoe wear, silicone innersoles, supportive stockings and exercises. The combination proved to be effective in preventing and/or managing lower limb disorders. The outcome of the current study provided evidence on the incidence of WRMSDs, and associations between risk factors and work posture, and WRMSDs among sewing machine operators managed within the programme.
Download or read book Cerebral Palsy written by Freeman Miller and published by JHU Press. This book was released on 2006-05-08 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a child has a health problem, parents want answers. But when a child has cerebral palsy, the answers don't come quickly. A diagnosis of this complex group of chronic conditions affecting movement and coordination is difficult to make and is typically delayed until the child is eighteen months old. Although the condition may be mild or severe, even general predictions about long-term prognosis seldom come before the child's second birthday. Written by a team of experts associated with the Cerebral Palsy Program at the Alfred I. duPont Hospital for Children, this authoritative resource provides parents and families with vital information that can help them cope with uncertainty. Thoroughly updated and revised to incorporate the latest medical advances, the second edition is a comprehensive guide to cerebral palsy. The book is organized into three parts. In the first, the authors describe specific patterns of involvement (hemiplegia, diplegia, quadriplegia), explain the medical and psychosocial implications of these conditions, and tell parents how to be effective advocates for their child. In the second part, the authors provide a wealth of practical advice about caregiving from nutrition to mobility. Part three features an extensive alphabetically arranged encyclopedia that defines and describes medical terms and diagnoses, medical and surgical procedures, and orthopedic and other assistive devices. Also included are lists of resources and recommended reading.
