The process of population ageing is observed not only in Poland but also in other European countries. Physiological processes of ageing  reduces the functional capacity. In particular, associated diseases, progressive weakness and failure of the motor system increases the risk of collapse in seniors. Dangerous consequences of falls, inter alia, injuries, can often cause death, what justifies its classification as a so-called geriatric giant. Health and psychosocial consequences of falls should be noted. Therefore, there is a great need for induction of preventive measures. Many results of studies constantly show, that an effective intervention in preventing falls in seniors should include, first and foremost, multidirectional rehabilitation, which aims to improve balance and increase postural strength muscle. In addition, prevention should include: patient education, pharmacotherapy prescribed by a medical specialist, eyesight improvement, elimination of potential risks surrounding the patient. The introduction of multi-directional prevention of falls can reduce the risk of their occurrence up to 50%

Aim: The purpose of this study was to show the characteristics of postural stability in the aging process of elderly people, using the stabilography method and risk assessment of falling occurring in this age group. Materials and methods: The overall study included 36 people engaged in the therapeutic process in Musculoskeletal Rehabilitation Centre in Krzeszowice ORNR. Their average age was 69,42 (± 7,12) years. The test consisted of unconstrained standing on the stabilograph platform for 30 seconds in different experimental conditions: (1) Unconstrained standing with open eyes, (2) Unconstrained standing with closed eyes, (3) Unconstrained standing with open eyes after 6 revolutions on the Barany’s chair. Results: This research showed that the posture of elderly people is characterized by higher values of displacement/COP lean in the sagittal plane rather than frontal plane. Furthermore, it demonstrated that limitations in impulses from sensory inputs (vestibular and visual system) result in an increase of oscillations of the stabilogram graphic curve. However, no strong link between the values of individual measurements (stabilogram) and the occurrence of fall was established. Conclusions: This study showed the usefulness of the stabilography method in describing the stability of the human body. Yet, in order to determine the objectivity of this method, further tests need to be done on larger sample groups and norms regarding people of different ages have to be elaborated. The results obtained in this research might however contribute towards the development of modern accident prevention programs.

Background Falls constitute an important health issue. They cause significant morbidity, mortality and have marked psychological effects on the individual, too. The aim of this study has been to determine parameters describing human movement strategies for balance and the reaction if balance is lost as a result of an unstable ground, and to attempt to describe the types of falls. Material and Methods The study group comprised 20 volunteers. Kinematic parameters of falling and dynamic stability were measured using the Vicon Motion System and the Biodex Balance System SD. During the test, subjects stood for 20 s on the tilting platform. The analysis was conducted based on the first recordings, when the participants were not prepared for the event and their reactions were natural. A cluster analysis tool was applied to divide the behavior of people during the test. Results Based on motion range for kinematic parameters, the cluster analysis revealed 2 types of human behavior: falling (stepping) and restoring balance. Two types of falls were also observed: side and back falls. Moreover, on the basis of angular values for tilting plate, 4 zones were determined. The frequency of access to these zones by each joint revealed 3 strategies to maintain balance: ankle, knee and hip strategy. Conclusions A set of initial conditions that may be used for future numerical simulations was also determined. Furthermore, the results presented in this study are likely to support the analysis of the effects and the falling patterns. Med Pr 2018;69(3):245–252
