An estimated 5000 people in the United Kingdom require a lower-limb amputation each year, and of these, some 53% are transtibial and 39% transfemoral. Three-quarters of all referrals for a lower limb amputation are caused by dysvascularity, infection accounted for 8% and trauma 7%.

The stump/sock interface is critical in the successful return of military amputees to active duty as it forms the mechanical interface between the subject and the prosthesis. Weight bearing, uneven pressures and friction through the residual limb need to be carefully managed to avoid skin breakdown, pressure sores and infection. Additionally the quality of the fit is fundamental for the comfort of the wearer. If the prosthesis is uncomfortable to wear or difficult to use, the amputee will be less inclined to wear it.

Accurate measurement of pressures and shear forces acting on the stump is vital to achieving optimum fit and alignment of a prosthetic limb. Previous research into pressure distributions during standing and gait at the stump/socket interface has produced varied results.

Direct pressure measurements during stepping-up, stepping-down and during the timed-up-and-go test have yet to be measured.

Research into pressure distribution and skin/stump integrity appears to fall along a continuum with aspects of engineering in the development of pressure sensors at one extreme and qualitative research investigating skin condition and prosthesis use adherence on the other extreme

Abstract

An estimated 5000 people in the United Kingdom require a lower-limb amputation each year, and of these, some 53% are transtibial and 39% transfemoral. Three-quarters of all referrals for a lower limb amputation are caused by dysvascularity, infection accounted for 8% and trauma 7%.

The stump/sock interface is critical in the successful return of military amputees to active duty as it forms the mechanical interface between the subject and the prosthesis. Weight bearing, uneven pressures and friction through the residual limb need to be carefully managed to avoid skin breakdown, pressure sores and infection. Additionally the quality of the fit is fundamental for the comfort of the wearer. If the prosthesis is uncomfortable to wear or difficult to use, the amputee will be less inclined to wear it.

Accurate measurement of pressures and shear forces acting on the stump is vital to achieving optimum fit and alignment of a prosthetic limb. Previous research into pressure distributions during standing and gait at the stump/socket interface has produced varied results.

Direct pressure measurements during stepping-up, stepping-down and during the timed-up-and-go test have yet to be measured.

Research into pressure distribution and skin/stump integrity appears to fall along a continuum with aspects of engineering in the development of pressure sensors at one extreme and qualitative research investigating skin condition and prosthesis use adherence on the other extreme
