Objective. To predict falls in osteoporotic females less than 65 years old. Material and method. Osteoporotic women distributed as follows: Group 1, 0-1 falls per year, and Group 2, 2-4 falls per year. Kinesthesia and statesthesia of the knee were assessed at 15°, 30° and 45° of flexion. Results. 30 patients, age range 49-65 years (mean 59, SD 4.21). Group 1: 20, Group 2: 10. The discriminating analysis reported a correct patient classification in 86.7% of cases based on kinesthetic and estatesthetic measurements. The most useful measurements to achieve proper classification were right kinesthesia at 15° and left estatesthesia at 15° and 45°. The COR curve showed that the best cut-off point for the absolute error was 3.15° at 15° of knee flexion of kinesthesia, with sensitivity of 80% and a specificity of 75% (AUC = 0.70, CI = 95%, 0.51-0.89, p=0.07). Conclusion. It is possible to predict the risk of having 2 or more falls in the past year through the assessment of knee kinesthetics at 15° of flexion, when the patient’s error threshold exceeds 3.15°.

Key words: osteoporosis, falls, proprioception, prognosis, aged.
