Study design
This was a randomised, prospective interventional study with each participant acting as their own control, with 12 weeks of a lead-in control period prior to 20 weeks of intervention (Fig. CONSORT diagramThe study procedures were performed by the same research team members who were unblinded to participants groups. Researchers were required to know the group frequency to provide appropriate monitoring of sessions and training progression (e.g. monitor correct frequency use, increase in frequency). In addition, the vibration frequency display can be easily observed by both researchers and participants, which unblinds participants to the group allocation.During the control period, participants continued with their usual lifestyle and were recommended to avoid starting any new activities during the study duration. Throughout the intervention period, in addition to activities during the control period, participants underwent sVT.
