Purpose:This study investigated the effects of the balanced incline shoes on the stabilized walking, fatigue reduction, improvement of blood circulation and prevention of foot related disease for the pregnant women.
Methods: The seven 7~9 month pregnant women and three maternities within 3 months after delivery without a history of disease performed the cycles for each of the two walking conditions: wearing balanced incline shoes and flat shoes. The differences between the two walking conditions were statistically investigated including three dimensional motion analysis, footprint pressures and blood flow. To find out any possible difference between these two kinds and among the subjects, the statistical tool was utilized with one-way layout design.
Results:Of 10 subjects, seven subjects showed the significantly decreased in distance of both knee with balanced incline shoes than flat shoes (P<0.05). Those with the balanced incline shoes had a walking pattern whose knee moved inward about 6 mm, compared to those with the flat regular ones. Over plantar pressure measurements for all ten, it also revealed statistically significant differences that the balanced incline shoes decreased its pressure 15% and that the pressure heavily on heel area was distributed outward along the arch (P<0.05). The blood stream velocity belonged to C (200~300 μm/sec) or D (100~200 μm/sec) for the nine before wearing the balanced incline shoes. However, it was found to be enhanced in A (>600 μm/sec) or B (400~600 μm/sec) after they put them on, indicating 1~2 part equivalent improvement. The blood stream velocity showed a incremental tendency after wearing balanced incline shoes.
Conclusions:This result suggests that the balanced incline shoes corrected the postures, stabilized the gait pattern, decreased the excessive load on ankle plantar flexors, reduced the fatigue level and improved the blood circulation.
