Socket fabrication is a highly refined art that relies on the skill and experience of the prosthetist. Despite best efforts, patients often return to the prosthetist with complaints of residual limb pain, socket discomfort and skin problems. To prevent problems such as these and resolve problems that have developed, the prosthetist relies primarily on verbal feedback from the patient and visual inspection of the residual limb. Clinical techniques for the quantification of biomechanical factors at the socket interface are not in common use. Specifically, the two commercially available interface pressure measurement systems, the Rincoe Socket Sensor and the Tekscan F-Socket Measurement Systems, are not employed by many prosthetists. This is perhaps due to cost, difficulty in clinical interpretation of the data, and time required for operation.1 Furthermore, these systems have not undergone any scientific evaluation for validity.
