In the second case, failing to maintain the forearms in a horizontal position can also trigger similar problems. This frequently occurs when users maintain their keyboards and mice on their desks instead of using a sliding keyboard and mouse tray. Prolonged use of keyboards and mice in an elevated position relative to the elbow causes wrist problems because of the continual downward bend required in the wrist. The solution to this type of hand and wrist problems is simply to use a pull-out keyboard and mouse tray that allows the user to keep the hands at the exact same height as the elbow without bending the wrist down at all during computer use.
Neck, Back, and Shoulder Problems
Prolonged computer use can also result in neck and back problems through similar mechanisms. When users fail to maintain the proper height of the computer monitor, they have a tendency to look...
Both situations result in neck strain in many instances. The simple solution is to make sure that the top of the computer monitor is level with the eyes.
Finally, prolonged computer use can also trigger back and shoulder problems. Generally, back problems are caused by desk chairs with insufficient lower back support. The resolution to these issues are often no more complicated than taking frequent breaks to increase circulation, using supportive desk chairs, and adding a foot support on the floor to ease the strain of prolonged sitting. Generally shoulder problems associated with computer use have to do with lack of efficient elbow support. The simplest solution is to make sure that the desk chair provides padded elbow support that enables the user to avoid straining the shoulder muscles holding the arms in the proper height for typing.
Computer Vision Syndrome According to the Computer Desktop Encyclopedia, Computer Vision Syndrome (CVS) is "A variety of problems related to prolonged viewing of a computer screen. Short-term effects include dry eyes, blurred vision, eye fatigue and excessive tearing. Long-term effects include migraines, cataracts and visual epilepsy. Some solutions are to keep reflections and glare to a minimum and to provide a non-fluorescent, uniform light source. Special lamps are available that maintain
However a more basic plan is to be adopted by firms with lower risk of these injuries. OSHA provided training to employers for implementing these guidelines. These training sessions are considered even more critical for small businesses which are at a higher risk of facing such injuries. OSHA also plans to conduct regular inspections to make sure these guidelines are being adhered to. It is the responsibility of the employer
Ergonomic Risk Assessment The human body encourages a specific posture and has muscles and joints which can become overstressed through repetition or overextension. Unfortunately, every job has actions which cause these types of problems. Injuries in the workplace are expected to a degree because it is impossible to determine every area that could cause an incident, but the science of ergonomics is used to act as a mitigating factor for some
Ergonomic Evaluation The aim of the following study was to conduct an ergonomic evaluation to identify contributing factors in the development of musculoskeletal pain and discomfort in Ultrasound Sonographers involved in Obstetric and Gynecological scanning. The methodology involved a cross-sectional study of Sonographers in one hospital. The methodology included the use of the Rapid Upper Limb Assessment (RULA) to identify the exposure to postural risk, static muscle work and repetition, and
Conversely, arm rests that are too high compress the wrist tendons because they cause a prolonged upward bend to allow the hands to reach the keyboard. Generally, carpal tunnel syndrome results from either prolonged stretching or compression of the wrist tendons within the fibrous sheath surrounding them. The other keyboard issue is that some computer users have a tendency to turn their hands outward in the horizontal plane. This
Core affect (CA) on the other hand refers to a neurophysiological state which is accessible consciously as very simple and yet nonreflective feeling which forms an integral part of hedonistic as well as arousing values. The hedonistic values are responsible for the feeling of pleasure and displeasure while the arousal feelings are activated by sleep. In the study of affect, it became clear that its core characteristics are many.
