Micro-vascular responses can reveal local malnutrition.Ĭhanges in local skin blood supply under various external loadingĬonditions have been studied for a number of years. Related to the formation of pressure sores due to uneven distribution It is generally believed that ischemia is Performed on the FH, and results revealed that lateralįorces play a major role and is influenced by theĪsymmetrical gait patterns. Interviews conducted were evident that patients endured Materials after longer period of time and increases the Implimentation, and thus reduces the wear of socket Would greatly benefit from the FH socket hole A patient that moves rather slowly,Īs a result of old age or sedentary level of activity Sockets with holes at fibula head (FH) and patient Worn areas show direct relations between relieved Patients where scanning electron images (SEM) of the With relief areas are appropriates for lower extremities

Patients varies at the limb socket interface according to Pressure distribution for transtibial amputees (TTA) A comparison of stress distributed in a number of socket designs was made to assess interface cushioning and suspension systems, among others. Different types of methods have been utilized to identify the locations of extreme stresses that might cause skin breakdown. This is why it is vital to measure the quantity of these interface stresses to measure the amount of damage the socket imposes on the residual limb tissues.
The prosthetic socket dispenses the entire weight of the amputee's torso while in the walking cycle. It is very significant to take into account the interface pressure of an amputee patient. This is because each patient's residual limb is unique and complex. The most demanding process is designing and fitting of the socket. Biomechanics of socket-residual limb interface, particularly the effect of pressure and force distribution, has on the amputee regarding comfort and function. A socket is an important part of prosthetic limbs it is an interface between the residual limb and prosthetic parts. The prosthesis consists of several essential parts such as socket, shank, ankle, and foot.
