Quality of Life of Patients With Metabolic Syndrome Is Improved After Whole Body Vibration Exercises

Abstract

Background:Whole body vibration exercises (WBVE) improve the quality of life (QoL) of different populations. Metabolic syndrome patients (MetS) may be favored by physical activity. Questionnaires are used to assess the QoL. The aim was to evaluate the QoL of patients with MetS that have undergone WBVE with a brief WHOQOL (WHOQOL-BREF).Material and Methods:MetS patients were randomly divided into three groups: (i) control group (CG), (ii) treated with WBVE once per week (WBVE1) and (iii) treated with WBVE twice per week (WBVE2). In the first session, the patient was sat in a chair in front of the platform with the feet on its base in 3 peak to peak displacements (2.5, 5.0 and 7.5 mm) and frequency of 5 Hz was used. From the second to the last session, patients were subjected to the same protocol, however they were standing on the base of the platform and the frequency was increased up to 14 Hz. The patients fulfilled the WHOQOL-BREF before the first and after the last sessions. Cronbach coefficients were determined to each domain of the WHOQOL-BREF and test Wilcoxon (p<0.05) was used.Results:The patients of the WBVE1 group had improvements in the physical, psychological and environment domains while in the WBVE2, the improvements were in the physical and social relationships domain of the WHOQOL-BREF.Conclusion:It was observed that the WBVE in a protocol (one or two times per week) with a progressive and increased frequency improves the QoL of patients with MetS in different domains of the WHOQOL-BREF.

Effects of 8-Week Whole-Body Vibration Training on the HbA1c, Quality of Life, Physical Fitness, Body Composition and Foot Health Status in People with T2DM: A Double-Blinded Randomized Controlled Trial

“…The effects of WBV training on quality of life and foot health in people with T2DM have been poorly studied. Regarding quality of life, previous studies showed that WBV could improve the quality of life in older populations [45] and other chronic conditions [46,47]. In this regard, a previous study of 6 weeks of WBV improved all domains (pain, general and mental health, vitality, physical, emotional, and social functioning) of the SF-36 quality of life questionnaire in people with diabetic neuropathy.…”

Effect of the Combined Intervention with Passive Whole-Body Vibration and Auriculotherapy on the Quality of Life of Individuals with Knee Osteoarthritis Assessed by the WHOQOL-Bref: A Multi-Arm Clinical Trial

“…One possible explanation to these discrepancies is related to differences in the intervention variables. Recent studies focused on the effects of WBVE intervention on daily physical functions in KOA individuals [45] used higher frequencies (35)(36)(37)(38)(39)(40) than the ones used in the current study. Moreover, Bokaeian et al, also reported improvements in symptoms of osteoarthritis of the knee and functionality; however, no significant differences were in pain or quality of life using a frequency of 25-30 Hz [22].…”

“…The sample size was determined using the formula n = [(Zα/2δ)/E] 2 , where, n = sample size; Zα/2-critical value for the degree of confidence, usually: 1.96 (95%); δ-population standard deviation of the variable; E-standard error, usually: ±5% of proportion of cases (absolute precision) or ±5% of the mean [37]. Ten individuals were thus chosen for each group, considering the values (mean ± SD) reported in a previous study that assessed the QoL of individuals with osteoarthritis [38]. Considering a possible decrease in sample size, one hundred and three subjects with KOA diagnosis were recruited (January 2014 to December 2017).…”

Evaluation of Health Related Quality of Life and Components of Metabolic Syndrome among Young Adults

“…19 Different questionnaire form used to evaluate the quality of life, criteria to estimate MetS and sample size may cause variations in results in different studies. 20 We assessed MetS in our study by using hermonized criteria (H_MS). HRQL evaluated by using SF 36 questionnaire among the young adults in our study.…”
