Abstract:
Objective To study the correlation between pain, lower limb strength and physical function in patients with primary osteoporosis. Methods Fifty-seven female patients diagnosed with menopause-related low bone mass or primary osteoporosis using a GE calcaneus bone density detector were involved in this study. The muscle strength of their lower limbs was tested with a Biodex system 4 machine. Pain was assessed with a visual analogue scale, and physical function (PF) with the SF-36 instrument. Results Low back pain was significantly correlated with PF, and so was leg pain. Leg pain was also significantly correlated with the strength of the extensors of the dominant leg during low velocity and medium velocity movement. Leg pain was not, however, significantly correlated with the strength of the flexors of the dominant leg during low and medium velocity movement. Conclusions Pain predicts poor physical function in patients with primary osteoporosis or low bone density. During low and medium velocity movement, leg pain significantly predicts poor muscle strength in the extensors of the dominant lower leg, but it has no correlation with the muscle strength of the flexors.
