Who Are We?
Our company was formed by four individuals who suffer from cumulative trauma illnesses. Our forearm supports, (Morency Rests) were initially developed to help get injured individuals back to work. They dramatically reduce the muscle activity in the neck and shoulders, increasing blood flow and dramatically reducing fatigue,discomfort, and pain. Our emphasis is on fitting the work to the individual, a dramatic departure in today's work environment and a true application of ergonomics.
All of our products were designed or chosen for their value in achieving a more comfortable and productive environment. We pride ourselves on our personalized service and our ability to customize our existing products or develop new ones to resolve your indiviual and sometimes unique applications.
Improved posture, neutral wrist positioning, and supported upper extremities dramatically improve comfort while reducing risk of injury. We manufacture products for varied applications and the size of the individual, making us unique in today's ergonomic market. R&D Ergonomics was established in 1991 and sells only quality products using materials from the United States.
Doesn't it make sense to you that the work should be focused on fitting you, instead of you trying to fit it! Do you drive your car with the seat adjusted for your spouse who is dramatically shorter or taller? Of course not! Then why do you work for hours at a desk that isn't adjusted for your unique proportions?
Current research indicates that static posture may be a more significant risk factor that repetitive motion! Our muscles were designed to work actively, pumping blood through them to bring in oxygen and removing the waste products formed when calories are burned. When muscles are tightened they restrict blood flow.
Take a short test yourself. Find an object that weighs a few pounds. Repeatedly lift and lower that object as if you were lifting weights. Most people have no problem doing this activity for several minutes. Now take that same weight and hold it up at arms length. Notice how rapidly muscle fatigue occurs! Far less actual work was done, but it was static muscle use work that our bodies are not designed to perform!

A Methodology To Implement and Validate Ergonomic Improvements To Computer Workstations At L.L. Bean
Conclusion: "Combining the subjective evaluations of employees with our own objective measurements, we are able to validate that our measured ergonomic improvements result in positive changes from the employees' perspectives. "Added upper extremity support (6" min) 62%" "One to two weeks after the ergonomic modifications, employees indicated an average 83.8% increase in their after modification comfort"

Relationship between Trapezius Load and The Incidence of Musculoskeletal Illness in the Neck and Shoulder
Conclusion: "These results clearly indicate that the static trapezius load must be kept at a minimum and at the same time the number of periods and the total duration of trapius load below 1% maximum voluntary contraction should be increased in order to reduce related musculoskeletal illness in the shoulder area."

Sustained Muscle Tension As A Risk Factor For Trapezius Myalgia
Conclusion: " Subjects who later developed trapezius myalgia during the first year of employment showed higher muscular activity of the trapezius muscle than healthy control during accidental pauses of manual work. Percieved exposure for physical and psychosocial risk factors at work were not significantly associated to "resting tension", but some risk factors showed a clear tendency to increase this tension. Sustained low-level muscle activity seems to be a risk factor for muscular pain. It may be an etiological factor, but may aldo inhibit miscle recovery after fatigue or microtraumatism".

Musculoskeletal Complaints in Hygiene: A Survey Study from a Swedish County
Conclusion: "The results of this study show thay there was a high frequency of musculoskeletal complaints among the Swedish dental hygienists surveyed. We consider the complaints to be due to long-standing static work load. This study led to further investigation of the workplace and an intervention study."

Ergonomic Evaluation and Construction of a Reference Workplace in Dental Hygiene: A Case Study
Conclusions: "....the dental hygienist experienced fewer complains in the shoulder region....the workplace has been noticed and appreciated by dentist and hygenist in several parts of Sweden."
There are many studies that indicate providing upper extremity support reduces the static muscle loading. These studies also indicate that all people performing all types to tasks would benefit from incorporating forearm support into their workstation design.
