Reportage on a sports instructor specialising in adapted physical activity in a specialised care home for adults with mutliple disabilities in France. The instructor helps a young man to walk. The Science and Technique of Physical and Sports Activities courses specialising in adapted physical activity aim to develop professional skills to help with people who have specific needs (physical, motor, mental or sensorial disabilities as well as social handicap and elderly people). Depending on the sector, adapted physical activity provides physical training, functional or motor rehabilitation and can be used for health reasons as well as for leisure or passtime activities.
