The last century handed us over a considerably older pop-ulation, particularly in the developed countries. Lifeexpectancy, which in the industrialized countries at thebeginning of the 1900's, was barely 47 years, has progres-sively increased and today is almost 80 years, with womenin an advantageous position. Moreover, the real qualita-tive leap is represented by the conditions in which ageingtakes place, conditions that till now were inconceivablefor past generations, such as the level of education, thehealth status and the economic resources.Senior citizens are eager to maintain their quality of lifebut at the same time ageing poses them significant prob-lems. This is due to the very important age-related modi-fications to the nervous and musculoskeletal systems. Infact, ageing modifies the properties of the neuromuscularsystem [1], reduces the conduction velocity of neural sig-nals [2], and in general the performance in complex sen-sory-motor tasks increasing the reaction time to externalstimuli [3]. Ageing is associated with a decrease in mentaland cognitive skills and also with an important reductionin motor abilities, which are often cause of increased riskof accidents [4,5]. Specifically, elderly subjects are gener-ally slower and less reactive than younger adults [6], andshow higher muscle co-activation, reduced muscular forceand power and reduced ability in force regulation [7].Moreover, elders have difficulties with sensory discrimi-nation, perceptual encoding, response selection andmotion preparation [8]. Even in able-bodied elderly peo-ple, it is possible to observe a natural reduction of cogni-tive performance as shown in [9] (Figure 1).The ability to maintain balance during locomotion is alsonaturally reduced due to ageing and this leads to fatigueand increased fall risks as the most important conse-quences [10]. Falling represents one of the most worryingevents for elderly people because it involves severalaspects of the autonomous daily life, healthy, costs for thesingle subjects and costs for the society in order to increasesuitable structures and manage employees, therapists andassistance.Differences can also be found in the analysis of reachingmovements [11]. Interestingly, elders seem to deal withthe modifications in their abilities by finding alternativesolutions customized to their conditions and possibili-ties. This is something we could expect: the change in theproperties of the plant asks for a redefinition of the con-trol strategies to (try to) achieve the same level of perform-ance.The analysis of the age-related modifications of motorcontrol strategies is a topic of extreme interest for manysocial and clinical reasons because of the significantreduction of elders quality of life due to these issues. Infact, understanding these modifications is important notonly to deep our basic scientific knowledge but also todevelop more effective systems to improve the quality oflife of elders. Many groups are now developing advancedtechnological solutions not only for seniors affected bydisabilities but also for able-bodied (but frail) elders [12](Figure 2). This new field of research (often called geron-technology which is the combination of gerontology –the scientific study of aging – and technology) cannot
