Introduction:

Despite the low evidence of the relationship between shoulder pathology and the use of computers, some authors associate this pathology with the use of the computer mouse, its position away from the body or insufficient space on the desk.

Clinical case:

We present the case of four workers who, during the last year, consulted medical services spontaneously, manifesting shoulder pain related to their working conditions and how this clinic has been solved by adapting the workplace, basically thanks to the introduction of a wireless mouse that allowed the redesign of the workplace.

Discussion:

The inability to move the mouse freely due to restrictions in the space of the work table and the use of mice more than 4 hours / day during the workday has been described as a cause of shoulder pathology. In other cases, it was also associated with insufficient space on the work table, having the mouse away from body position or using it during half or more of the workday.

From a biomechanical point of view the rotator cuff is demanding to avoid dislocating forces, which it does by means of eccentric contraction or neutralizing forces of antagonist groups. The supraspinatus plays an important role at the beginning of abduction with a maximum traction angle of approximately 75°. Certain positions may influence your fatigue and / or inflammatory process.

Conclusions:

Our experience indicates that a simple and acceptable modification of the position of the shoulder during the use of the mouse has been useful to improve events of clinical presentations like tendinopathies at this level.
