Multiple vibration displacements at multiple
vibration frequencies stress impact on human
femur computational analysis

Bertram Ezenwa, PhD; Han Teik Yeoh, PhD


Maximum stress levels of femur model: (a) 35.77, (b) 53.66, (c) 107.30, and (d) 214.62 MPa.

Veterans who are bedridden while recovering from injuries will benefit from technology that initiates muscle contraction to improve bone strength when they are unable to engage in physical activities. This article presents the development and pilot test called multiple vibration displacements at multiple vibration frequencies (MVDMVF) for efficient recruitment of muscle groups while a patient stands on the platform. The advantage of MVDMVF is that the use of high displacement levels is unnecessary for improving bone strength because of efficient muscle recruitment. Our results from testing MVDMVF on a veteran subject showed that MVDMVF improved bone strength. We also included the veteran's comments about comfort of use.
