About us

MultiSim is an Engineering and Physical Sciences Research Council (EPSRC) funded programme awarded to The University of Sheffield to develop a multiscale modelling framework of the human musculoskeletal system.  MultiSim aims to generate computer simulations that help diagnosis and provide patient-specific treatment recommendations.

In addition, to saving time and money, the new computer tools will provide a more reliable diagnosis of the disease, a better treatment, and a detailed prognosis and monitoring of the treatment. The final goal of such a programme is to improve patients’ quality of life.

Aims 

This project aims to create a new generation of predictive models capable of handling complex multi-scale and multiphysics problems, characterised by uncertain and incomplete information. This will secure the considerable breadth of our vision. The depth of the vision will be achieved by applying such radically new approaches to modelling the musculoskeletal system by integrating all interactions across space-time from the cellular scale up to the whole organism scale, individualised to each patient.

MultiSim: The rationale behind our research 

The project focuses on the establishment of a currently non-existent but essential computational platform for the management of musculoskeletal disorders. The need for such a platform is essential considering that total healthcare expenditure in the UK has doubled from 2000-2010 to a staggering 10% of GDP. During this period about half of the annual cost increase has been attributed to the use of new technologies or the intensified use of old ones, such as the increased use of CT scans. To control the spiralling cost, models are required to pre-assess patient specific diagnosis and treatment procedures, to predict the benefits, quality of life improvement and costs; in brief, to aid decision making for the individual patient.

To address this, the European Commission has spent more than €200M in the last 5 years on collaborative research projects developing the Virtual Physiological Human (VPH). The VPH is a methodological and technological framework that will enable investigations of the human body as a single complex system, which will be individualised to each and every one of us. This is both a great vision and the ultimate challenge that this project addresses in the multi-scale modelling of the human musculoskeletal system.

This project will enable computational simulations that are not currently possible. Overcoming the currently insurmountable challenges in biological systems which arise from overlapping scales, partially observable states, and uncertainty will provide the VPH breakthrough and will also enable the development of much needed models of other complex engineering problems.
