Objective: To determine the effect of foot orthoses on pain, disability and foot functionality in patients with Systemic Lupus Erythematosus. Design: Randomized clinical trial. Setting: University Podiatric Clinical Area. Subjects: Patients with systemic lupus erythematosus. Interventions: Patients were randomly assigned to either group A, which received custom-made functional foot orthoses, or group B, which received flat cushioning insoles, for three months. Main measures: The primary outcome was foot pain, measured by 11-point numeric pain rating scale. Foot functionality and foot-related disability were evaluated using the foot function index, the Manchester foot pain and disability, at the beginning and at days 90. Results: Sixty-six participants (age 47.3 ± 11.9 years) suffering from foot pain, received either the custom-made foot orthoses (N = 33) or the flat cushioning insoles (N = 33). For the analysis of the data, only participants who had finished the follow-up period (90 days) were included. None statistically significant difference between groups were found. In group A, all variables showed statistically significant differences when comparing the initial and final measurements. Pain showed 6.8 ± 1.6 and 4.2 ± 2.9 in group A, at baseline and at 90 days, respectively, group B showed 6.5 ± 1.5 and 4.7 ± 3.0 at baseline and at 90 days, respectively. Conclusion: Both groups showed a reduction in foot pain. This study suggests that not only controlling the foot function, but providing cushioning to the foot, may have positive effects to manage foot pain in patients with systemic lupus erythematosus.

Objective: The aim of this work was to study the relationship of torsional and rotational parameters of the lower limb with a specific angular position of the cleat to establish whether these variables affect the adjustment of the cleat. Design: Correlational study. Setting: Motion analysis laboratory. Participants: Thirty-seven male cyclists of high performance. Interventions: The variables studied of the cyclist's lower limb were hip rotation (internal and external), tibial torsion angle, Q angle, and forefoot adductus angle. Main Outcome Measures: The cleat angle was measured through a photograph of the sole and with an Rx of this using the software AutoCAD 2008. The variables were photograph angle (photograph), the variable denominated cleat-tarsus minor angle, and a variable denominated cleat-second metatarsal angle (Rx). Analysis included the intraclass correlation coefficient for the reliability of the measurements, Student's t test performed on the dependent variables to compare side, and the multiple linear regression models were calculated using the software SPSS 15.0 for Windows. Results: The Student's t test performed on the dependent variables to compare side showed no significant differences (P = 0.209 for the photograph angle, P = 0.735 for the cleat-tarsus minor angle, and P = 0.801 for the cleat-second metatarsal angle). Values of R and R2 for the photograph angle model were 0.303 and 0.092 (P = 0.08), the cleat/tarsus minor angle model were 0.683 and 0.466 (P < 0.001), and the cleat/second metatarsal angle model were 0.618 and 0.382, respectively (P < 0.001). Conclusions: The equation given by the model was cleat-tarsus minor angle = 75.094 - (0.521 × forefoot adductus angle) + (0.116 × outward rotation of the hips) + (0.220 × Q angle).
