Working at a computer monitor is very stressful for your shoulders. The trapezius muscle lifts and stabilises the shoulder. In order to perform properly, this muscle requires an adequate supply of energy and adequate waste product removal. Contracting the muscles forces blood out due to the pressure on the blood vessels. When the muscles relax, the blood vessels are no longer subjected to pressure and can open again. This is why a regular cycle of contraction and relaxation is good for blood circulation in the muscles.
Applying a static load to the shoulders hinders good blood circulation. When you work with hunched shoulders, there is no ‘muscle pump function’. The waste products remain in the muscles. The pain that this can cause makes you contract the muscles again. Thus completing a vicious circle. This situation is known as “acidification” of the muscles and is one of the most common causes of RSI. Consequently, it is important to adopt a work posture that allows you to relax your shoulders.
Shoulder complaints can be very unpleasant. You can reduce or even cure them with ergonomic aids from Ergonomique. Wrist supports, monitor stands, laptop stands and document holders contribute to adopting the right work posture.
