This study investigated user satisfaction and prosthesis use in the ICRC/ SFD project in Vietnam. Clients who were satisfied with the use of their prosthesis were compared to those who were not. Similarly, those with no or light use (0-4 hours/day) were compared with those using the prosthesis more frequently. Multivariate logistic regression was done. Data(More)
Forty-three (43) trans-tibial prostheses with a mean period of use of 33 months were evaluated in terms of utilisation and durability. The majority of the prostheses (80%) were worn by amputees with demanding occupations, such as farmers, fishermen and tradesmen. The prostheses were in use approximately 9 hours per day. No major or frequent breakdowns of(More)
A sand-casting technique for trans-tibial sockets was applied to 28 amputees, and the prosthetic fit observed through transparent check sockets. The results were better than historical reports of fittings with plaster of Paris casting by qualified prosthetists. The fit was consistently and evenly larger than the stump, but total contact could be achieved by(More)
A sand-casting technique for transtibial sockets was applied to 28 amputees in 2005. Although this meant an improvement in the quality of fitting as compared to historical reports with plaster of Paris casting, a total contact required three (two to five) stump socks. Continuing research leads the inventor, Dr Y. Wu, to replace the sand with micro(More)
