permeability and thermal conductivity which advance orthosis use and wear comfort. An increase in the

the corrective forces. The corrective forces and ⁄ or support that control the deformity of joints or bones
can therefore be adjusted by altering the number of layers of composites. The use of fibre composite
materials in orthoses not only improves the prevailing problems of wear discomfort, but also facilitates
the control of corrective forces, thus enhancing the quality of orthotic intervention.},
