Preprint

Background Knee osteoarthritis (KOA) is one of the leading causes of global disability which causes knee pain, stiﬀness, and swelling. Impaired neuromuscular function contributes to the development and/or progression of KOA. As a new modality to treat KOA, whole-body vibration (WBV) training is considered to improve pain and physical function effectively. However, limited numbers of studies were designed to investigate the effect of WBV on neuromuscular function in KOA.Methods 81 eligible participants with KOA were randomly allocated to WBV, strength training (ST) and health education (HE) groups. Each group of participants was encouraged to perform the WBV training, similar strength training and health education program, respectively. These supervised interventions were performed three times per week for 8 consecutive weeks. Neuromuscular function was measured with isokinetic muscle strength and proprioception. Physical function was assessed with Timed Up and Go (TUG) and 6-min Walk Distance tests. Results Physical function and neuromuscular function did not show significant difference between three groups (p > 0.05). However, post-hoc test showed that isokinetic knee muscle strength of WBV group (peak torque of extensor at 180°/s, peak torque of flexors at 180°/s, peak work of extensor at 180°/s, and peak work of flexor at 90°/s, all p < 0.05) increased significantly compared with HE group. Similarly, compared with ST group, muscle strength of WBV group (peak torque of extensor at 180°/s and peak work of extensor at 180°/s, p < 0.05) improved significantly. Conclusion The current study showed that the advantage of WBV training on muscle strength gain in patients with KOA compared with similar strength training without vibration and health education.Trial registration It was registered at Chinese Clinical Trial Registry a priori as a clinical trial (ID: ChiCTR-IOR-16009234). Registered 21 September 2016.

“…Compared with other groups, the physical function did not improve more effectively in the WBV group, whereas the TUG and 6MWD results were enhanced after 8 weeks of WBV training. Similar to our results, several studies failed to verify the superior effect of WBV on physical function [ (25,31,40)]. However, after WBV training with longer or more frequent [ (33)].…”

Background Knee osteoarthritis (KOA) is among the most common osteoarthritis diseases that affect adults older than 65 years old. Impaired neuromuscular function contributes to the development and/or progression of KOA. As a new modality in strength training, whole-body vibration (WBV) training is considered in the management of KOA. However, the inconsistent results of previous studies dampened the enthusiasm for the clinical application of WBV. Methods Eligible participants with KOA were randomly allocated to WBV, strength training (ST) and health education (HE) groups. Finally, 57 participants completed the intervention and measurements. The participants in each group were encouraged to perform the WBV training, similar strength training or health education program. These supervised interventions were performed three times per week for 8 weeks. Physical function was assessed with Timed Up and Go (TUG) and 6-min Walk Distance tests. Neuromuscular function was measured with isokinetic muscle strength and proprioception. Results All variables of physical function and neuromuscular function failed to change significantly among three groups (p > 0.05). However, compared with the baseline, the time of TUG (mean difference = 0.88 ± 0.78, 95% CI = 0.50 – 1.26, p < 0.001) and most of the variables related to isokinetic knee muscle strength (peak work of flexor at 90°/s, peak torque of extensor at 180°/s, peak work of extensor at 180°/s, peak torque of flexors at 180°/s, and peak work of flexors at 180°/s, all p < 0.05) improved significantly in WBV group. Conclusion WBV training has been recommended for strength training in elderly people and patients with musculoskeletal diseases. The 8-week WBV training under the protocol of our study was not superior to ST and HE. Hence, more clinical studies are required in the future to develop an optimal training protocol. Trial registration It was registered at Chinese Clinical Trial Registry a priori as a clinical trial (ID: ChiCTR-IOR-16009234). Registered 21 September 2016.

“…After reviewing the information in the titles and abstracts, 750 papers were read in detail. Finally, 5 RCTs [ 28 – 31 , 37 ] (168 participants) with valid outcome data met the inclusion criteria and were included in this analysis. The process of identifying these studies from initial publication searches to final inclusion is illustrated in Figure 1 .…”

“…Ronikeile and Costa [ 27 ] reported the benefits of WBV for people with OA by systematically reviewing several studies. Several trials have reported that WBV can alleviate pain, improve balance control, and improve gait pattern and other parameters [ 28 , 29 ]. However, some trials failed to find significant improvements in pain intensity or other parameters among patients with KOA [ 30 , 31 ].…”

et al. 2015

Objectives. To assess the effects of WBV exercise on patients with KOA. Methods. Eight databases including Pubmed, EMBASE, Cochrane Library, CINAHL, Web of Science, the Physiotherapy Evidence Database, CNKI, and Wanfang were searched up to November 2014. Randomized controlled trials (RCTs) of WBV for KOA were eligible. The outcomes were pain intensity, functional performances, self-reported status, adverse events, and muscle strength. A meta-analysis was conducted. Results. Five trials with 168 participants provided data for the meta-analysis. No significant difference was shown in pain intensity and self-reported status between WBV and other forms of exercise. Improvement in functional performance (evaluated by BBS; WMD, 2.96; 95% CI, 1.29 to 4.62; P = 0.0005) was greater in WBV group, but the other parameters of functional performance (including 6MWT and TGUG) revealed no statistically significant difference. Adverse events were only reported in one trial and no significant difference was discovered in muscle strength. The overall quality of evidence was very low. Conclusion. Currently there is only limited evidence that suggested that WBV is effective in the treatment of KOA. Large, well-designed RCTs with better designs are needed.
