Discussion
The efficacy of two exercise programmes aiming to improve postural control in women with osteoporosis was assessed in this study. Positive results were found for both interventions, but with differential efficacies for specific variables. The strengthening
group was superior to the control group in the CTSIBm test (unstable surface/closed eyes) and in the Limits of Stability Test (centre of pressure velocity and directional control). Stretching group participants was better than those in the control group in
velocity of centre of pressure, and in variables related to amplitude of movement. The strengthening group was better than the stretching group only for directional control in the Limits of Stability Test, and the stretching group was not better than the strengthening group for any of the postural control variables.
