ntroduction: Plantar fasciopathy (PF) consists of a painful affection of the feet, being one of the main causes of pain in the hindfoot that causes abstention to work and reflects in the great demand for treatment in the orthopedic offices. Conservative treatments account for 90% of back pain pain resolutions and are associated with therapies that include joint mobilization, stretching, insoles, shockwave therapy, and laser therapy. However the use of insoles is restricted for use in closed shoes such as shoes and sneakers, and this can be an obstacle to treatment in cities with hot weather. Objectives: To evaluate the effectiveness of the insoles adapted in slippers in the improvement of pain and function in individuals with persistent pains in the back of the city of Santa Cruz, RN. Methods: A randomized, double-blind, randomized clinical trial of 66 patients diagnosed with persistent back pain, randomized into two groups: slipper insole group (CP) (n = 34) received a custom strip slipper with foot pieces and perforated beige synthetic leather. The plain flip flop group (CL) (n = 34) received a perforated beige synthetic leather cover slipper, identical to the one used by the intervention group, but without the corrective parts. Participants were instructed to wear the slipper 4 hours a day for 12 weeks. Two evaluations were performed: one before the intervention protocol (T0) and the second after the 12 intervention weeks (T12). The primary outcome was pain with Visual Analogic Scale (VAS). As secondary endpoints were foot function by the FFI (Foot Function Index) questionnaire and foot and ankle functionality by Foot and Ankle Ability Measure (FAAM). The functional capacity by the 6-minute walk test (6MWT). Likert scale for assessing patient satisfaction with his insole. Results: The CP group significantly improved the pain experienced in the morning through the variable EVA morning (p = 0.016); with no differences between the groups for final EVA of the day, TC6 and FAAM. Another statistically significant value was obtained from the FFI variable, where the CP group presented a result (p = 0.023), thus showing improvement in foot function after flip-flops. Conclusion: Insoles adapted in slippers as a form of treatment for 12 weeks for persistent back pain, especially FP, were effective in improving pain in the morning and in foot function.
