Faculty of 1000 evaluation for Functional performance and inflammatory cytokines after squat exercises and whole-body vibration in elderly individuals with knee osteoarthritis.

Knee osteoarthritis (KOA) can cause functional disability. Neuromuscular function is relevant in the development and progression of KOA. It can be evaluated by the analysis of the surface electromyography (sEMG), which has an important role in the understanding of KOA. Whole-body vibration (WBV) is an intervention suggested to treat KOA. The objective of this work was to verify the effectiveness of WBV on the functionality of lower limbs by the electromyographic profile of the vastus lateralis (VL) muscles during the five-repetition chair stand test (5CST) in patients with KOA. This was a two-period crossover trial study (8-week washout). Nineteen patients with KOA were allocated to the group submitted to WBV (WBVG), with peak-to-peak displacement of 2.5 to 7.5 mm, frequency from 5 to 14 Hz, and acceleration peak from 0.12 to 2.95 g, or to the control group (0 Hz) (2 days per week for 5 weeks). The 5CST and the sEMG of the VL during 5CST were evaluated before and after the interventions. Results: Significant differences in 5CST were evident only in WBVG (p = 0.018), showing a decrease of the execution time. The sEMG profile showed no significative difference. Therefore, only 10 sessions of WBV with comfortable posture can bring about improvement in functionality of KOA patients without alteration of the muscle excitation.

Combined Intervention

The aim of this study was to determine the effect on the quality of life of two non-pharmacological interventions isolated or in combination: (i) passive whole-body vibration exercise (WBVE), and (ii) auriculotherapy (AT). One hundred three participants with knee osteoarthritis (KOA) were allocated to: (a) a vibration group (WBVEG; n = 17) that performed WBVE (peak-to-peak displacement: 2.5 to 7.5 mm, frequency: 5 to 14 Hz, Peak acceleration: 0.12 to 2.95 g), two days/weekly for five weeks, (b) an AT group (ATG; n = 21), stimulation of three specific auriculotherapy points (Kidney, Knee and Shenmen) in each ear pavilion, (c) WBVE + AT (WBVE + AT; n = 20) and (d) respective control groups (WBVE_CG, n = 15; AT_CG, n = 12; WBVE + AT_CG, n = 18). The participants filled out the WHOQOL-bref Questionnaire before the first and after the last sessions. Statistical differences in the various domains of the WHOQOL-bref were not found. In conclusion, WBVE or AT alone or combined did not contribute in altering the quality of life of individuals exposed to these interventions.
