It results in trapping of sweat, creating ideal conditions for bacteria and fungus to thrive. This can lead to skin irritation, abrasion and skin breakdown. Various factors make the stump vulnerable to skin diseases, which can hamper quality of life (QoL) of an amputee. Amputation stump dermatoses (ASD) can occur immediately after socket fitting, or many years after amputation. It has been reported that Amputation stump dermatoses affects 34–78% amputees. Of these ~29% are caused due to mechanically induced stump dermatoses. The design of the stump is a major contributor to stump dermatoses as improper design results in poor fitting, trapping of sweat in closely fitted socket of prosthesis, close contact of materials leading to irritation or an allergy. The high prevalence of stump dermatoses has let to there being a growing importance given to prevention, early management and advanced treatment of skin diseases. The use of new edge technologies in designing the stump socket helps to a greater extent in preventing skin diseases resulting from the above mentioned factors. Biomaterials used in the prosthesis further reduces the risk of these skin diseases. This paper discusses the design techniques and considerations of the stump socket as key measure in prevention of the mechanically induced stump dermatoses.

These can often cover K2 and K3 grades of mobility. To achieve a wider mobility, these electronic knees depend upon feedback sensors which provide real-time data to a microcontroller. Various methods are used to calculate the joint motion and knee angle which include magnetic encoder, electro goniometer, and inertial measurement units. The goal of this paper is to develop a sensor to measure angular change of the “stump” socket using accelerometer and ultimately that of the thigh movement, and to use it as feedback signal to the microcontroller in the electronic knee. Sensing the thigh position directly can help in achieving a more natural gait. This feedback system can be used instead of the passive feedback systems currently used in the electronic knees. Results show the potential of low-cost sensing method as a reliable feedback system which can reduce complexity of the hardware as well as the algorithms currently used in the development of modern electronic knee, and hence the overall cost of the electronic knee.
