Background and aim: The aim of this study was to verify the relationship between pelvic tilt and lumbar lordosis with muscle tightness, muscle strength, BMI, and age in standing position.

Material and methods: In this study, 75 healthy female subjects participated with age range 20-70 years, mean (SD) = 40.66 (13.69). Pelvic tilt and lumbar lordosis were measured in standing position with pelvic inclinometer and flexible ruler respectively. The length of muscles, including: erector spinae, iliopsoas, rectus femoris, hamstrings, tensor fascia lata & ilio tibial band, and gastrocnemius were assessed by Schober, Thomas, Ely, 90/90 SLR, Ober tests and passive dorsiflexion of foot, respectively. The strength of muscles, including: rectus abdominis, transversus abdominis, left & right obliqus, Gluteus maximums & medius, and quadriceps were evaluated by manual muscle tests.

 Results: The relationship between pelvic tilt and lumbar lordosis with muscle strength, BMI, and age was poor. Muscle tightness and muscle strength had no significant effect on pelvic tilt and lumbar lordosis.

Conclusion: The results of this study indicated that the evaluated variables including: pelvic tilt and lumbar lordosis, have poor correlation with muscle tightness, muscle strength, BMI, and age.
