Workplace Factors That Lead To Shoulder Pain

studies are always trying to shed more and more light upon the question of joint pain, and the different contributing factors. In a recent article in the Annals of Rheumatic Diseases by bone and Tooper, looked at how prolonged exposure to repetitive activity at work contributes specifically to shoulder pain. In their study, they noted that population based studies suggest a lifetime prevalence of over 70 percent for neck and shoulder pain.

They found that shoulder pain was second only to back pain in workers compensation insurance claims. their study also found that the risk of developing shoulder pain when starting a new job is related to the amount of over-the-head lifting and the monotonous nature of the work. They concluded that shoulder pain is a common problem among working age adults and is a large contributor to sick leave.

The study was able to identify some of the workplace factors that contribute to shoulder pain. The researchers were able to identify prolonged abnormal posture and repetition as significant contributors to shoulder pain. They also noted that more recent studies have considered the psycho-social influences such as monotony of work and the amount of stress might also contribute to shoulder pain.

In their conclusions, they call for more studies looking at psycho-social stressors as wells as repetative movement and how it can be modified in order to prevent further injuries to the shoulder in the workplace setting. Such a finding could greatly benefit the 70% of the population that suffers from some sort of work-induced joint pain.

Wireless vs Traditional

Why are some people reluctant to try new technologies? Technology exists to better peoples lives by making tasks easier, more convenient, increase their knowledge, and save both monies and time. change takes time for some people but it is important to know that the longer one takes to learn and use technology, the faster it changes and chances are, technology and culture will pass you by. Technology is developing rapidly with some innovations becoming obsolete almost as quick as they are discovered. This age of work and entertainment has seen many changes in technology with some drastically changing the world as we know it. satellite and communications technology have brought us the ability to communicate in real time with people from different countries around the globe. Never has it been any cheaper or easier to conduct business or exchange personal communications with anyone anywhere. Technology exists to improve peoples lives and should be accepted as a part of life.

Traditional technologies included many restrictions because of geographical limitations but wireless technology applications have expanded beyond the boundaries of time and space. Many people use wireless technology without knowing as wireless technology is also an integral part of dialup, cable, and DSL technologies. Companies continue to upgrade traditional technology using wireless technology making it impossible to realize that the combination of the old and the new makes tasks easier and cheaper for all. Wireless devices do not require cables or wires to transport data/voice/imagery options. This eliminates geographical, time, access, and expense restrictions making communications with others immediate.

company expenses to install wireless devices equipment, logistics, and agreements are minimal when compared to the overall costs of trenching cables. Time to revenue ratios are greatly reduced with wireless devices because most wireless systems can be functional within hours instead of weeks or months. Immediate sales of services are permitted because there are no longer any waiting periods for services to be installed or completed and connected. Wireless technology enhances broadband access and extends the capabilities of other markets including cable and DSL. Wireless is an alternative to broadband wire lines and provides accessibility in locations without loop access. Security concerns seem to be the only drawback of wireless systems because signals transmitted through air can be intercepted by anyone who might be scanning airwaves for unprotected signals. encryption signals have been standardized to make wireless as safe as wired in home settings. There are no computer networks completely safe but both wireless and wired have assurances and protections against security risks.

Wireless technology seems to be the present and future of our civilization as it provides mobility, maximum performance of devices, and economic and financial feasibility. Dont resist changes - expand your horizons and knowledge as wireless technology networking continues its reform of traditional forms of communications.
