I am working with amputees and assessing the effect of different prosthesis on the gait of TT amputees. The majority of research papers in this area model the prosthesis as a normal lower limb and do not therefore account for the altered mechanisms, especially in designs such as the Flex Foot. I have read only one paper (Prince et al at CSB last year) which proposes an alternative method. Has anybody done any research in this area, ie to assess if the inverse dynamics approach is applicable for amputee gait? Looking forward to the responses, Siobhan Hillery, Brunel University College, Osterley Campus, Isleworth, Middlesex, England __________________ For the one like Siobhan Hillery who are interested in a more complete technique for energy calculation that can be used in any foot prostheses, please read the following. I have published a full paper on a new technique for the biomechanical assessment of foot prostheses. Prince, F., Winter, D.A., Sjonnesen, G. and Wheeldon, R.K. (1994). A new technique for the calculation of energy stored, dissipated, and recovered in different ankle-foot prostheses. IEEE Transactions on Rehabilitation Engineering, vol. 2, 247-255. A more clinical paper is under review and I will include the reference when available.
