Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The objective of this study is to investigate the impact of variable frequency, low amplitude cycloidal vibration therapy in elderly adults (aged 60-70) and to estimate the change in participants’ body composition, hematological, rheological, protein blood parameters and fibrinogen concentration.
The patients will receive vibrotherapy treatments 30 vibration therapies during three months, in the morning, once a day, five times a week. They will be obligated to participate in three courses while one course comprises ten vibration treatments and ten days of resting. One vibration treatment will last 29 minutes and include 8 microprograms. The treatments will be performed in a prone position with the use of the RAM Vitberg+ Base Module (active medical device, class IIa) enhanced with the module RAM Vitberg+ Metabolism (active medical device, class I). The whole RAM Vitberg+ system combines the general action following the WBV rule (Whole Body Vibration – oscillations of a general character) with local action applying additional therapeutical module in which the vibration impulse of RAM Vitberg+Metabolism is directed towards the areas of: epigastrium, mid-abdomen, pubic region, inguinal region, lateral and hypochondriac regions of abdomen, superficial fascia and the layer between subcutaneous tissue and abdominal muscles. The indexes of the applied vibration change in time according to the characteristics of the program. Each intervention is the same medical program written by the manufacturer of the medical device, which includes various frequencies and amplitudes that change over time during the intervention. The therapeutical stimulus consists of cycloid vibrations, produced in three perpendicular directions (3D), inducing intermittent pulsations with variable values of frequency (f), amplitude (A), and acceleration (a), that ranges between 25-52 Hz, 0.1-0.5 mm, and 6.9-13.5 m/s2, respectively.
All of the trainings will be carried out at the same time of day (in the morning) by the same, qualified physiotherapist (with minimum 5 years' experience), in a room with the same temperature and humidity. Each volunteer will be qualified by a physician before participation in the study. The session attendance checklists will be used to monitor adherence to the intervention. The therapy will take place at Physiotherapy Practice in Skawina, Poland and will be supervised by the members of the University of Physical Education in Krakow, Poland.

Statistical methods / analysis
The distribution of results for the analyzed variables will be checked applying the Shapiro–Wilk test. For single measurements, the signifcance of group-related differences will be assessed using independent-sample tests, Student’s t-test or the Mann–Whitney U test. In vibration group (VG) and control group (CG) the values of differences will be assessed between the first and second examinations and the level of statistical significance will be estimated with the pairs order Wilcoxon test. Comparing the impact of vibration treatments on changes in the analyzed variables among the compared groups, the analysis of variance with repeated measures (ANOVA) will be used, examining the infuence of the main factors, i.e., Group (Vibration and Control), Treatment (infuence of Vibration Therapy) and Group × Treatment interaction for variables of normal distribution. The statistical signifcance of differences will be assumed for the level of p < 0.05.

Summary
Brief summary
Elderly people need activities that will positively contribute to a satisfactory process of getting older. We hypothesize that vibration training, similarly to other forms of physical activity, affects metabolic processes and condition of health, The aim of the work is to assess the influence of thirty vibration treatments on body fatness, hematologic and rheologic indexes of blood, proteinogram and fibrinogen concentration in elderly adults' blood. The study will include 90 adults, aged 60-70 years who will be randomly assigned into a vibrotherapy group (VG) taking part in interventions on mattresses generating oscillatory-cycloid vibrations and a control group (CG), without interventions. In all patients the following assessments will be performed twice: assessment of body fatness by the bioimpedance method, a complete blood count with a hematology analyzer, and erythrocyte aggregation by a laser-optical rotational cell analyzer, whereas total plasma protein and fibrinogen values will be established, respectively, by biuret and spectrophotometric methods. In order to compare the impact of vibrotherapy on changes in the analyzed variables, the analysis of variance (ANOVA) or the Wilcoxon test will be used.
