Foot and ankle-foot orthoses are prescribed in order to promote mobility through supporting and/or realigning the lower leg and alleviating pain in the foot in different parts of the gait cycle. This paper will outline new approaches to the design and manufacture of personalised foot and ankle-foot orthoses (FO and AFO) using additive fabrication(More)
This paper assesses the possibility of using Rapid Manufacturing (RM) as a final manufacturing route through a comparison of RM processes capabilities vs. conventional manufacturing processes. This is done by means of a computer-aided system intended to guide the designer in the selection of optimum production parameters according to typical requirements of(More)
Ankle-Foot-Orthoses (AFOs) are assistive devices prescribed for a number of physical and neurological disorders affecting the mobility of the lower limbs. Traditional AFO design is based on thermoforming polymer sheets around a plaster cast with a characteristic stiffness depending on the selected trim-line with the inherent design limitations. Additive(More)
BACKGROUND The design of foot and ankle orthoses is currently limited by the methods used to fabricate the devices, particularly in terms of geometric freedom and potential to include innovative new features. Additive manufacturing (AM) technologies, where objects are constructed via a series of sub-millimetre layers of a substrate material, may present the(More)
Plantar foot surface temperature has been identified as a clinically relevant physiological variable. Embedding sensors in foot orthoses (FOs) may allow long term monitoring of these temperatures, with compliance via the detection of periods of activity being a potential clinical utilization. This study aimed to test novel designs for FOs with embedded(More)
Background Before launching a new bespoke foot orthotic (FO) product, it is necessary to understand how it works under compressive loads. Additive manufacturing and the selective laser sintering process in particular can enable a number of innovative and functional features to be integrated to the FO device. A simple example of this design freedom is to(More)
