Plantar Pressure in Transtibial Amputees

Prosthesis is the preferred method for the rehabilitation of the amputee and prosthetic fitting requires processes and based on knowledge of the biomechanical behavior of the prosthesis wearer procedures. Thus, understanding the adaptions that occur due to the loss of lower limb is an important aspect in devising a successful rehabilitation program. Therefore, in the Service Amputees and Prostheses at Hospital Militar Central we did a cross sectional descriptive study with observational component for measuring distribution of plantar pressure in patients transtibial amputees due to trauma by land mines. The study population consisted of seven men with unilateral transtibial amputation, aged 29 and 40 years with proper use of prostheses for over a year, with appropriate adaptation, prosthesis with suspension liner and pin and foot in carbon fiber. Distribution of plantar pressure was measured during standing using shoe insoles with 99 capacitive sensors. Foot plantar pressure is the pressure field that acts between the foot and the support surface during everyday locomotor activities. Information derived from such pressure measures is important in posture research for diagnosing lower limb problems, prosthesis alignment and other applications. All patients showed a pressure distribution asymmetry of the foot plantar soft tissue under each foot. In the non-amputated side pressure is greater in the heel and midfoot, while in the amputated side pressure is in the head of the first metatarsal and the medial heel.
