Abstract
[Purpose] We examined the relation between spine curvature angle and lower limb muscle strength in elderly females. [Subjects] The subjects were 52 community-dwelling elderly females (78.2 ± 6.1 years old). [Methods] We measured thoracic spine kyphotic angle, lumbar spine lordosis angle, quadriceps femoris muscle strength and lower limb loading force, and their inter-relations were analyzed with Pearson's correlation coefficient. [Results] Lumbar spine lordosis angle was significantly correlated with quadriceps femoris muscle strength and lower limb loading force. However, thoracic spine kyphotic angle showed no significant correlation with the lower limb muscle strength. [Conclusion] These results suggest that elderly females whose lumbar spine lordosis angle decreases have weaker quadriceps femoris muscle strength and lower limb loading force.
