“…Non-pharmacological interventions for RA that include foot orthoses and footwear can reduce pain and disability and improve long-term outcomes with existing and potential foot problems [8]. Previous studies have reported on the clinical effectiveness of foot orthoses in people with established RA, ranging from simple insoles to customised foot orthoses [9][10][11][12]. Clark [13] reported that few studies have undertaken a cost effectiveness analysis to investigate the cost implication of the prescription of foot orthoses for people with established RA, despite the high prevalence of foot involvement and the high direct cost of RA related health care to the UK economy.…”

“…The main function of the orthotic insoles used in this study was to reduce the peak pressure under the heel [12], because the elastic insole material deforms at each walking step, increasing the contact area with the foot [25]. These Table 2.…”

Abstract-Foot orthoses and night splints have been used separately to treat patients with plantar fasciitis, but were not always successful. Combined use of both orthoses might give better outcomes. This study evaluated the effectiveness of a soft and self-adjustable dorsiflexion night splint in combination with an accommodative foot orthosis for patients with plantar fasciitis. Twenty-eight patients were assigned to group A (foot orthosis only) and group B (combination of foot orthosis and dorsiflexion night splints). A Foot Function Index (FFI) questionnaire was used to evaluate the pain and functions of feet just before, 2 weeks after, and 8 weeks after the treatments. Results showed that subjects in group B had significantly reduced pain scores at week 2 (p < 0.001) and week 8 (p < 0.001). In group A, no statistical differences were noted in the pain (p = 0.15), disability (p = 0.56), activity limitation (p = 0.75), and total FFI (p = 0.35) scores for the three time periods. The application of foot orthoses with adjustable dorsiflexion night splints was found to be more effective than the application of foot orthoses alone in relieving foot pain in patients with plantar fasciitis.

“…It was found that the calcaneus and tibia, gravity center of foot would be affected after orthosis (Stacoff et al 2000;Hayakawa 2012). The mean pain index of the metatarsal head was significantly reduced from 7.6 to 1.1 using dynamic impression insole (Chang et al 2012 Figure 1(a)). The insole with a thickness of 6 mm was developed by CATIA V5 (CATIA Dassault System Corporation, France) ( Figure 1(b)).…”

Orthopedic insole was important for partial foot amputation (PFA) to achieve foot balance and avoid foot deformity. The inapposite insole orthosis was thought to be one of the risk factors of reamputation for foot valgus patient, but biomechanical effects of internal tissues on valgus foot had not been clearly addressed. In this study, plantar pressure on heel and metatarsal regions of PFA was measured using F-Scan. The three-dimensional finite element (FE) model of partial foot evaluated different medial wedge angles (MWAs) (0.0°-10.0°) of orthopedic insole on valgus foot. The effect of orthopedic insole on the internal bone stress, the medial ligament tension of ankle, plantar fascia tension, and plantar pressure was investigated. Plantar pressure on medial heel region was about 2.5 times higher than that of lateral region based on the F-Scan measurements. FE-predicted results showed that the tension of medial ankle ligaments was the lowest, and the plantar pressure was redistributed around the heel, the first metatarsal, and the lateral longitudinal arch regions when MWA of orthopedic insole ranged from 7.5° to 8.0°. The plantar fascias maintained about 3.5% of the total load bearing on foot. However, the internal stresses from foot bones increased. The simulation in this study would provide the suggestion of guiding optimal design of orthopedic insole and therapeutic planning to pedorthist.
