Sensory neuropathy is prevalent in people affected by leprosy and diabetes. If neuropathy is left untreated it may lead to further impairments, which may be irreversible. Customized methods to identify and prevent further impairments in patients with sensory neuropathy are essential. The possibility of a sensory feedback system to identify pressure values on an anaesthetic foot was tested in this study. The feedback system to measure the peak plantar pressures was designed by integrating an electronic circuit to the data acquisition system. The sensor head of the Force Sensing Resistor (FSR's) placed at various plantar pressure areas of the foot, determined the respective peak plantar pressures, based on sensing force. Feedback about the peak plantar pressure through the alerting terminals helps the user alter his gait and maintain the pressure within a set threshold limit. The system could also help the health staff to determine the patient's peak plantar pressure and thus design customized therapeutic footwear.

Introduction: Plantar ulcers occur in patients with peripheral arterial disease or peripheral neuropathy. Plantar ulcers resulting from the peak plantar pressures often lead to disabilities and even amputations. Using an appropriate offloading device would reduce peak plantar pressures and prevent ulcers.Objectives: To design and analyze a customized lightweight offloading device that will improve patient compliance and provide good aesthetic value, without compromising on efficacy. Computer Aided Design (CAD) software SOLIDWORKS was used to design two different 3-dimensional models of offloading devices. The light weight, energy efficient and cosmetically appealing offloading devices could be a replacement for the traditional offloading devices made of Plaster of Paris, which are bulky and unappealing, leading to poor compliance. Results: The computer simulation studies have established the efficacy of the new designs in offloading the foot. Conclusion:The developed designs could be an ideal replacement for traditional offloading devices like the Bohler iron. The designs could improve the user's compliance and acceptance without compromising on the efficacy. These designs need to be field tested.
