Association between unilateral functional ankle instability, limited ankle dorsiflexion range of motion and low back pain

There is growing evidence that supports the correlation between incidence of ankle dysfunction and low back pain (LPB). Although spine seem like distant regions body, they are functionally connected by lower extremity kinematic chain. The aim current study was to investigate association functional instability (FAI), limited dorsiflexion (DF) range motion (ROM) One hundred two subjects with chronic sprain participated in this study. mean ± SD age, weight, height, BMI group were 43.5 12.96 years, 85.27 14.22 kg, 172.9 8.45 cm, 28.59 4.72 kg/m². LPB measured Visual Analogue Scale (VAS), FAI anterior drawer test DF ROM lunge test. All statistical analyses performed using Statistical Package for Social Studies (SPSS) version 25 Windows. no statistically significant BMI, pain, sex (p > 0.05). a (odd ratio 5.68, p = 0.02) 1.16, 0.01). supported previous studies recommending as factor LPB. authors suggest conducting similar larger number participants include measures scales or questionnaires increase validity generalizability results.
