Abstract

Introduction: The decrease in postural control and muscle strength in lower limbs have been identified as major risk factors for falls in older people. Exercises have proven effective in decreasing risk factors in healthy elderly, but little is known about the effects of interventions with exercise in the elderly with osteoporosis. Objective: To compare the efficacy of two exercise programs - the first consisting of balance training and muscle strength and the second consisting of balance training and muscle stretching exercises to improve postural control in elderly women with osteoporosis. Methods: Fifty elderly aged 65 or older, with a diagnosis of osteoporosis, were randomized into 3 groups: Strength Group (n = 17) performed balance training with muscle strengthening; Stretching Group (n = 17) performed balance training with stretching; and Control Group (n =16) did not do activity. The groups trained for 8 weeks, with sessions of about 60 minutes, twice a week. Postural control was evaluated by CTSIBm and LOS test in Balance Master force plate, the functional balance by Berg Balance Scale, muscle strength by dynamometry, the shortening of the hamstrings by goniometry and posture by SAPO software. Results: The Strength Group was superior to control in functional balance, dorsiflexion strength and knee flexion strength, COP velocity and directional control (both in test LOS), and oscillation velocity (CTSIBm test). Stretching Group was greater than control in functional balance, shortening of hamstrings, strength in knee flexion, COP velocity, endpoint excursion and maximum excursion (the last 3 in LOS test) and forward head. The Strength Group was better than Stretching Group in extension strength and directional control. Conclusion: The results suggest that both treatments are effective in improving postural control when compared to Control Group, and Strength Group was better than Stretching in knee extension strength and directional control.
