This study aimed to investigate the effects of an exercise program with a focus on postural control exercises in frail older adults.Method: Twenty-six older adults (76.7 ± 4.9 years) deemed clinically stable, chosen from the Falls Unit, University Hospital Mútua Terrassa, Barcelona, Spain, participated in this single-group study. Volunteers' postural control was evaluated using the Timed Up and Go test (TUG) and the Guralnik test battery, and their static and dynamic posturography were evaluated using the Synapsys Posturography System®. These evaluations were performed before and after the intervention program, which included an educational session and two weekly 1-hour sessions over an 8-week period of stretching exercises, proprioception, balance, and motor coordination. Data were analyzed using the Student's t-test or the Wilcoxon test, with a significance level of 5%.Results: The TUG and Guralnik tests did not show significant differences. Concerning static posturography, there was improvement in the base of support (P = 0.006), anteroposterior displacement with eyes open (P = 0.02) and closed (P = 0.03), and the total amplitude of the center of pressure with eyes closed (P = 0.02). Regarding dynamic posturography, a decrease of the oscillation speed in the anteroposterior direction (P = 0.01) was observed in individuals with their eyes open.Conclusion: The program used in this study was safe and was able to promote some improvement in postural control, especially in the anteroposterior direction and in the base of support. However, it is noteworthy that further improvements could be obtained from a program of longer duration and greater frequency.Keywords: balance, aging, intervention, fall

White Book on Physical and Rehabilitation Medicine (PRM) in Europe. Chapter 4. History of the specialty: where PRM comes from

In the context of the White Book of Physical and Rehabilitation Medicine (PRM) in Europe, this paper deals with the history of the PRM medical specialty. The specialty evolved in different European countries, and sometimes also into the single countries, from different medical streams that finally joined. These included among others: balneology, gymnastic, use of physical agents (water, heat, cold, massage, joint manipulations, physical exercise, etc.). Another important role has been played by the increasing number of people experiencing or likely to experience disability due to improvement of medicine and consequent survivals from wars, accidents and/or big infective epidemics (like polio); these evolutions happened in strict relationship with other specialties like cardiology, neurology, orthopaedics, pneumology, rheumatology, traumatology, creating a knowledge transversal to all of them. Consequently, the PRM specialty has been gradually introduced in the different European countries, however with no uniformity. Subsequently, European Organizations were created for its diffusion and coordination at the level of medical competences and patient care as well as medical teaching and research: The European Federation of Physical Medicine and Rehabilitation - later European Society (ESPRM), The Académie Médicale Européenne de Médecine de Réadaptation (EARME), The PRM Section of the European Union of Medical Specialists and the European College of PRM (served by the UEMS-PRM Board), were created and work today regarding these general aims. Nowadays a uniform definition of the specialty exists in Europe, which is concordant with the internationally accepted description of PRM (based on the ICF-model). Moreover, research in PRM has been mainly improved during recent decades in Europe due to some external as well as internal scientific influences, thus increasing its scientific importance, together with a parallel increase in rehabilitation journals, many of them indexed and some with impact factor (Cr, EJPRM, JRM, among others), as well as a parallel increase in scientific congresses and courses. Last but not least, the recent creation of the Cochrane Rehabilitation field will also give a great boost to this primary medical specialty, as well as the discovery on new physical agents and technologies that diminish activity limitation and participation restriction of disable persons
