This prospective, randomized, single-blinded study assessed variables immediately before and after a 12-week training program. For the allocation of participants, a 1:1 ratio randomization was performed using opaque envelopes for the concealment of allocation. To minimize the chance of bias, opaque, sealed, and serial-numbered envelopes were used that were opened sequentially (only after the participant's name and further details were written on the envelope) and kept in a locked, secure place.
The characteristics of the sample population are shown in table 2. There were no significant differences in age, sex distribution, body height or weight, body mass index (BMI), or the OA grade among the 3 groups (P>.05), which confirmed the baseline homogeneity of the groups. The average age of the participants was 72 years, and the mean BMI was 28.7kg/m2. Most of the sample (87.5%) were women.
All participants in both intervention groups complied with the full intervention program. The overall
The results of this study showed that the addition of vibration to squat exercise training improved gait performance and static and dynamic balance and decreased biomarkers and self-perception of pain in elderly patients with knee OA.
The addition of whole-body vibration to squat exercise training generates vertical sinusoidal vibrations that stimulate the primary endings of the muscle spindles, activating α-motor neurons that result in muscle contractions that are comparable to the tonic
The addition of vibration training to squat exercise training improves static and dynamic balance and gait performance. Also, the addition of vibration training reduces the self-perception of pain and inflammatory markers in elderly patients with knee OA.

Five trials included unsupervised exercise programs38,42,44,47,50 while the remaining trials included some degree of supervised exercise29–37,39–41,43,45,46,48,49,51,52. Twenty-one trials reported outcomes measured at short-term follow-up29,30,32–39,41,44–54,56, eight at medium-term follow-up30,34,40,42,43,50,55,57 and seven at long-term follow-up30,31,35,40,42,43,55. Detailed descriptions of interventions can be found in Appendix 2.
This scoping review found nine studies which assessed the effects of WBVT on pain in KOA (Avelar et al., 2011; Bokaeian et al., 2016; Lai et al., 2019; Moura-Fernandes et al., 2020; Park et al., 2013; Salmon et al., 2012; Simão et al., 2012; Tsuji et al., 2014; Wang et al., 2016). Out of these, five studies demonstrated an improvement in pain after WBVT (Avelar et al., 2011; Moura-Fernandes et al., 2020; Park et al., 2013; Simão et al., 2012; Wang et al., 2016) while other four reported a non-significant improvement in pain after WBVT (Bokaeian et al., 2016; Lai et al., 2019; Salmon et al., 2012; Tsuji et al., 2014). Unfortunately, impact of unstable surface WBV on pain in KOA is not established.
