Figure 1.
On the left (A) is a participant with triaxial accelerometers secured to the distal femur (large arrow) and distal tibia (medium arrow) and a uniaxial accelerometer secured to a platform that emits a high-frequency, low-magnitude vibration (HLV) signal when turned on (small arrow). On the right (B) are sinusoidal waveforms showing signals at the HLV platform, distal tibia, and distal femur in the vertical (V), mediolateral (ML) and anteroposterior (AP) axis while standing before the HLV platform is turned on (pre-HLV), while it is on (HLV) and after it is turned off (post-HLV).
