| dc.title | Comparison of plantar pressure distribution patterns between foot orthoses provided by CAD-CAM and foam impression methods | en_US |
| dcterms.abstract | Foot orthotic treatment is one of the major conservative methods to handle foot problems. Total contact foot orthoses are used to reduce and redistribute peak pressures. For the fabrication of total contact insole, computer-aided design and computer-aided manufacturing (CAD- CAM) method becomes more popular. In this study, the plantar foot-orthosis interface pressure data during walking were collected by the Novel Pedar-mobile in-shoe plantar pressure measuring system. Data were collected under 3 conditions: (1) flat insole, (2) foot orthosis provided by CAD-CAM method and (3) foot orthosis provided by foam impression method. The Swiss Comfort CAD-CAM foot orthotics system was used in this study. For conditions 2 and 3, foot shapes were collected in partial weight bearing and subtalar neutral conditions. Thirty normal subjects were recruited in this study. The plantar foot surface was divided into eight plantar foot regions were investigated. These regions included the heel, the medial and lateral mid-foot, the medial, mid and lateral forefoot, the hallux and the lateral toes. The results showed that the orthoses provided by both CAD-CAM and foam impression methods could decrease the peak pressure and the maximum force in the heel region and increase the peak pressure and the maximum force in the medial mid-foot region. Both orthoses redistributed the peak pressure and the maximum force from the heel to medial mid-foot area. The peak pressure in the mid forefoot regions were different between the orthoses provided by the CAD-CAM and foam impression methods. The results of this study provided more information for the selection of appropriate orthotic treatment method for different foot problems. | en_US |
