Background Plantar fasciitis (PF) in an inflammation of the fascia o on the bottom of the foot, characterized by stiffness in the medial arch and ankle, especially during one’s first steps, and can have a significant effect on activities of daily living. An insole is one of the most often employed conservative methods for the treatment of PF. The total contact insole (TCI) is the most recommended, as it redistributes the load uniformly throughout the sole of the foot. However, few studies have demonstrated the effectiveness of this device and there is no consensus on which type of insole is the most adequate.
Objectives The aim of the present study was to assess the effectiveness of a TCI regarding pain relief in patients with PF.
Methods Seventy-four patients with plantar fasciitis (33 of whom had pain in both feet) were randomly allocated into a study group (total of 57 feet) using a total contact insole and control group (total of 50 feet) using a sham insole. Evaluations were performed of pain (VAS); quality of life (SF-36); foot function (FFI and FSHQ); walking distance in six-minute walk test and foot pressure analysis using the AM Cube FootWalk Pro program. The groups were evaluated at baseline and after 45, 90 and 180 days by a blinded assessor. Data were analyzed using the intention to treat approach.
Results The groups were homogeneous regarding the majority of variables at baseline. In the comparisons over time, statistically significant differences between groups were found for pain when walking (p=0.003) and the 6MWT (p=0.006). Improvements occurred in both groups with regard to pain at rest, foot function and some quality of life parameters (functional capacity, bodily pain, vitality and social aspects) without statistically significant differences between groups. No changes in foot pressure were found with the use of the insole.
Conclusions Total contact insole can be used to reduce pain when walking and increase walking distance among individuals with plantar fasciitis.
