In rehabilitation, achieving mobility in autonomy is a major target. In case of a gait deficit, the manual wheelchair is the ultimate tool for achieving this target: it is a key device in the world of assistive technology (AT) and its use helps to increase the chances of the person with a disability, his/her independence and participation in the activities of daily living. To make best use of the device a training programme is needed. The person has to learn a new kind of locomotion: he/she must learn to make transfers to and from the wheelchair, how to face stairs and inclines.

This good practice deals with a statistical methodology in computer science to measure the workers welfare inside a company. We consider the company as a micro-society where wellness depends on both internal organizational factors and external factors related to work. We consider the working wellness as a multidimensional entity which can be interpreted through a set of indicators explored by the O.H.Q. (Organizational Health Questionnaire, 2002) questionnaire. A relational database and the SQL query language ensure portability and independence of the solution.
