- Abstract
- Background: A major secondary complication which can arise in individuals with spinal cord injury (SCI) is disuse-related bone loss as a result of long-term paralysis and immobilisation. An emerging rehabilitation technique used to treat this musculoskeletal degeneration is whole body vibration (WBV). This can be applied to patients in different body positions on a WBV platform in order to stimulate different muscle groups and in turn apply muscle forces to target bones. To treat the disuse-related bone loss, the hypothesis is that WBV intervention can stimulate bone formation indirectly via targeted muscle action, and/or directly if vibration acts as a mechanostimulus on the bone. Aim & Objectives: The aim of this study was to develop whole body computational models of WBV intervention, to inform the design of intervention protocols in SCI patients. Effects of muscle loss were simulated, and activation and forces of different muscles analysed for a number of proposed configurations on the WBV platform. Methods: WBV intervention was simulated using the AnyBody Technology Modelling software by implementing and adapting the currently available standing model. Different body positions (standing, knee flexed standing, squatting) and parameters of WBV such as frequency and amplitude were modelled and analysed, and the muscle actions simulated. Results: Realistic muscle activities compared to the literature were found in all body position configurations without the WBV simulation. When modelling the WBV intervention, only the squatting body position and side-alternating WBV plate were found to give accurate results. The activities of several muscles were recorded in this configuration under a variety of frequencies and amplitudes. Finally muscle forces were analysed with changes in frequency and amplitude and found to cause a corresponding change in the loading of regions the bones of the ilium, tibia, femur, ischium, fibula, sacrum and coccyx. The aim is for the results of this model to be used in the future to inform WBV protocol development for musculoskeletal rehabilitation in SCI and other target patient groups.
