• Functional leg length inequality
• Pelvic adjustment

[Purpose] This study was conducted to evaluate the influence of pelvic adjustment on functional leg length inequality (FLLI) and foot pressure. [Subjects] The study subjects were 40 adults who were healthy but had FLLI of at least 10 mm. Subjects were randomly assigned to two groups, an experimental group (n=20) and a control group (n=20). [Methods] The subjects of the experimental group underwent pelvic adjustment 3 times a week for 4 weeks. A tape- measure was used to measure FLLI, and F-Scan was used to measure the heel pressure difference (HPD) and the 1(st) metatarsal pressur difference (MPD). For all subjects, the lengths of both legs were measured before the intervention, and at 2 weeks and 4 weeks after the intervention was started. [Results] Pelvic adjustment was effective at reducing FLLI HPD and 1(st) MPD. HPD and the 1(st) MPD were reduced in proportion to the reduction in FLLI. FLLI was effectively reduced after 2 weeks of intervention and the reduction was more remarkable after 4 weeks. [Conclusion] We presume that pelvic adjustment reduces FLLI and foot pressure difference and that foot pressure difference is reduced in proportion to the reduction in FLLI. In conclusion, we consider that pelvic adjustment is suitable for reducing FLLI as well as foot pressure difference.
