Background The last century handed us over a considerably older population particularly in the developed countries. Life expectancy which in the industrialized countries at the beginning of the 1900 s was barely 47 years has progressively increased and today is almost 80 years with women in an advantageous position. Moreover the real qualitative leap is represented by the conditions in which ageing takes place conditions that till now were inconceivable for past generations such as the level of education the health status and the economic resources. Senior citizens are eager to maintain their quality of life but at the same time ageing poses them significant problems. This is due to the very important age-related modifications to the nervous and musculoskeletal systems. In fact ageing modifies the properties of the neuromuscular system 1 reduces the conduction velocity of neural signals 2 and in general the performance in complex sensory-motor tasks increasing the reaction time to external stimuli 3 . Ageing is associated with a decrease in mental and .
