Repetitive strain injuries and ergonomics concerns have become increasingly significant health issues as a growing number of individuals frequently use computers for long periods of time. Currently, limited software mechanisms exist for managing ergonomics; the most well-known are "break-reminder" packages that schedule and recommend typing breaks. Yet despite the proven benefits of taking breaks, such packages are rarely adopted due

This paper reviews the ergonomic and psychosocial factors that affect musculoskeletal disorders at the workstation. First is a model of a physiological assessment protocol that incorporated SEMG monitoring while working at the computer. Next is a study that showed that participants lack awareness of their muscle tension as compared to the actual SEMG levels. The final study illustrated how an intervention program can reduce RSI symptoms, decrease respiration rate, and lower SEMG activity. Recommendations include suggestions that successful safety and prevention programs need multiple components and that participants should to be trained to control physiological responses with respiration and SEMG biofeedback. All participants should master these physiological skills just as they learn how to use the computer.

In the present article design of a different angle to the monitor screen in respect to desk is prescribed. The angle is much lower than what is practical with the bulky terminals, due to the design limitations of which instinctively and compulsorily make user eyes to be kept unnaturally upward, and the head in uncomfortably backward tilted position, when viewing the screen. Our design facilitates natural positioning of the user body organs at screen front. Other important feature of our design is that user arms do also operate in a more normal height, at a lower continuous step integrated with the desk, when working with mouse and keyboard. Carpal tunnel syndrome seems to be alleviated in this way, but not totally removed. The step height also provides other necessary compartmentalization features, which is missing in most desk designs today.

Perhaps the most interesting thing about placebos and conditions such as repetitive strain injury is just how embarrassing we find them. The embarrassment stems partly from the seeming inexplicability of the phenomena, partly from the implication that what has happened to your body is not real, and that you could make yourself healthy through an act of will if only you would try. Critics of mainstream biomedicine sometimes say that we should just accept the idea that the mind can work on the body. But our current model is of the body as a machine. Asked how the mind works in it, the best we can do is to imagine a ghost turning the levers. Given the mechanical model, a placebo might as well be a magic wand, or an amulet to ward off spirits. We do not yet have the conceptual tools to describe how the mind works on the body, and without those tools, placebos and psychogenic illnesses look like magic. What do you say to the witch doctor who can reliably make it rain?

The purpose of this project was to summarise the available evidence on the effectiveness of exercise therapy for patients with disorders of the musculoskeletal, nervous, respiratory, and cardiovascular systems. Systematic reviews were identified by means of a comprehensive search strategy in 11 bibliographic databases (08/2002), in combination with reference tracking. Reviews that included (i) at least one randomised controlled trial

This study investigated the effects of myofascial force transmission during dynamic shortening of head III of rat extensor digitorum longus muscle (EDL III). The anterior crural compartment was left intact. Force was measured simultaneously at the distal EDL III tendon, the proximal EDL tendon and the distal tendons of tibialis anterior and extensor hallucis longus muscles (TA+EHL). Two types of distal shortening of EDL III were studied: (1) sinusoidal shortening (2 mm) and (2) isokinetic shortening (8 mm). Sinusoidal shortening of EDL III caused a decrease in force exerted at the distal tendon of EDL III: from 0.58 (0.08) N to 0.26 (0.04) N. In contrast, hardly any changes in proximal EDL force and distal TA+EHL force were found. Maximal concentric force exerted at the distal tendon of EDL III was higher than maximal isometric force expected on the basis of the physiological cross-sectional area of EDL III muscle fibers (Maas et al. 2003). Therefore, a substantial fraction of this force must originate from sources other than muscle fibers of EDL III. Isokinetic shortening of EDL III caused high changes in EDL III force from 0.97 (0.15) N to zero. In contrast, changes in proximal EDL force were much smaller: from 2.44 (0.25) N to 1.99 (0.19) N. No effects on TA+EHL force could be shown. These results are explained in terms of force transmission between the muscle belly of EDL III and adjacent tissues. Thus, also in dynamic muscle conditions, muscle fiber force is transmitted via myofascial pathways.

BackgroundThe CUPID (Cultural and Psychosocial Influences on Disability) study was established to explore the hypothesis that common musculoskeletal disorders (MSDs) and associated disability are importantly influenced by culturally determined health beliefs and expectations. This paper describes the methods of data collection and various characteristics of the study sample.Methods/Principal FindingsA standardised questionnaire covering musculoskeletal symptoms, disability and potential risk factors, was

Much of the empirical research on the effectiveness of different instructional designs has focused on declarative tasks, where a learner acquires knowledge about a certain topic. It is unclear to what extent findings for learning declarative tasks (which are not consistent on all aspects) carry over to learning procedural tasks, where a learner acquires a certain skill. In this paper, we describe an experiment studying a specific kind of procedural instructions, namely exercises for the prevention of repetitive strain injury (RSI), taking information modality (text versus picture versus film clip) and difficulty degree of the exercises (easy versus difficult) into account. In the experiment, participants had to learn RSI exercises and were asked to execute them. The results showed that an instruction in a picture lead to the shortest learning times followed by an instruction in a film clip. An instruction in text led to the longest learning times. For the amount of practicing the ex...

Increased demands on catalogers to increase productivity, while maintaining quality and accuracy, can be difficult to meet, and may even be hazardous to their health. OCLC Passport for Windows (PFW) and CatME provide some ability to create macros and shortcuts to speed cataloging activities, but do not solve the problems created by long work sessions. Voice recognition software, which works

Although the Internet has received significant attention in recent years, voice is still the most convenient and natural way of communicating between human to human or human to computer. In voice applications, users may have different needs which will require the ability of the system to reason, make decisions, be flexible and adapt to requests during interaction. These needs have placed new requirements in voice application development such as use of advanced models, techniques and methodologies which take into account the needs of ...

Upper extremity tendinopathies are associated with performance of forceful repetitive tasks. We used our rat model of repetitive strain injury to study changes induced in forelimb flexor digitorum tendons. Rats were trained to perform a high repetition high force (HRHF) handle-pulling task (12 reaches/min at 60 ± 5% maximum pulling force [MPF]), or a low repetition negligible force (LRNF) reaching and food retrieval task (three reaches/min at 5 ± 5% MPF), for 2 h/day in 30 min sessions, 3 days/week for 3–12 weeks. Forelimb grip strength was tested. Flexor digitorum tendons were examined at midtendon at the level of the carpal tunnel for interleukin (IL)-1β, neutrophil, and macrophage influx, Substance P, connective tissue growth factor (CTGF), and periostin-like factor (PLF) immunoexpression, and histopathological changes. In HRHF rats, grip strength progressively decreased, while IL-1β levels progressively increased in the flexor digitorum peritendon (para- and epitendon combined) and endotendon with task performance. Macrophage invasion was evident in week 6 and 12 HRHF peritendon but not endotendon. Also in HRHF rats, Substance P immunoexpression increased in week 12 peritendon as did CTGF- and PLF-immunopositive fibroblasts, the increased fibroblasts contributing greatly to peritendon thickening. Endotendon collagen disorganization was evident in week 12 HRHF tendons. LRNF tendons did not differ from controls, even at 12 weeks. Thus, we observed exposure-dependent changes in flexor digitorum tendons within the carpal tunnel, including increased inflammation, nociceptor-related neuropeptide immunoexpression, and fibrotic histopathology, changes associated with grip strength decline. © 2009 Orthopaedic Research Society.
