Abstract

Background and Aim: Hyperkyphosis can lead to reduced respiratory capacity, postural disturbance and increased risk of falling. Despite the evidences about the more postural stiffness and kyphosis in elderly compared with young subjects and despite the known role of sex hormones and menopause in lowering the bone density, there is not any study about the effect of sex on the amount of thoracic kyphosis. The objective of this study is measuring and comparing the amount of spinal thoracic kyphosis and postural stiffness between the old females and males.
 
Methods and Materials: In this descriptive-analytical study, in 36 healthy old subjects (21 female and 15 male) the amount of spinal thoracic kyphosis was measured by flexible ruler mounted between the spinous process T12 and C7 during, relaxed and erect postures. The difference of the kyphosis in relaxed and erect posture was used as an index of postural stiffness. The kyphosis and postural stiffness was compared between the females and males.
 
Results: The average amount of kyphosis in relaxed and erect standing didn’t have statistically significant difference between females and males. The subjects in both groups could decrease theirs kyphosis in standing erect position (P=0.0001), but the amount of this decrease (postural stiffness) was not different between the females and males.
 
Conclusion: In old women (which aren’t osteoporotic) hormonal changes due to menopause didn’t induce a statistically significant difference compared to old men in kyphosis and postural stiffness.Postural stiffness was increased by increasing the BMI that could suggest the BMI as an efficient factor in reducing the mobility of the spine.
