Effect of Exercises on Quality of Life in Patients with Postmenopausal Osteoporosis – Randomized Trial

BACKGROUND: Osteoporosis is a systemic skeletal disease characterised by a low bone density and microarchitectural deterioration of bone tissue leading to decrease of its strength and increased risk of fracture. Drug therapy decreases the risk of fracture, thus influencing on the mechanism of bone remodelling. Non-pharmacological interventions include specific exercises for osteoporosis that improve muscle strength and balance, decrease pain and improve quality of life. AIM: To compare the quality of life in patients with postmenopausal osteoporosis who practice exercises with those who do not practice on the beginning and after a year. MATERIJAL AND METHODS: A randomised Single-blind randomised controlled prospective trial study, which included 92 women with postmenopausal osteoporosis diagnosed and treated at the Institute of Physical Medicine and Rehabilitation in Skopje, Republic of Macedonia. Patients were randomly assigned to three groups: the first group of patients with exercises and physical modalities (gr. I), the second group with exercises (gr. II), and the third control group of patients who did not practice exercises (gr. III). Exercises were practised 3 times a week; each exercise was repeated for 5-8 times. Patients regularly took bisphosphonates, calcium and vitamin D. The follow-up period lasted for one year. Quality of life was determined with a specific questionnaire Qualeffo-41. RESULTS: The results showed, significant statistical difference in terms of pain, physical activity, social life, the perception of own health were shown between the groups (p < 0.0001), only in term of mental function were no significant (p < 0.3). CONCLUSION: Patients who practice exercises for osteoporosis have a significantly better quality of life than patients who do not perform exercises.
