Abstract
Statement of the Problem: In the study of muscle performance, movement has to be described in terms of velocity and acceleration. Force causes acceleration; movement is the action of force along a distance in a certain time, and is therefore measured as power. Our purpose was to study differences in muscle function of pre and postmenopausal women and women with rheumatic diseases.
Methodology & Theoretical Orientation: 257 women were included in the study separated in three groups: Group POST OST included 61 osteoporotic postmenopausal women taken anti osteoporotic drugs and calcium/vitamin D supplementation (mean age 65±9.6 years), group POST HEALTH consisted of 117 healthy postmenopausal women (mean age 62.9±9.8 yrs), Group RHEUM included 20 women with rheumatic diseases (mean age 58.85±13 yrs), and group PRE included 59 healthy premenopausal women (mean age 35±7.6 yrs). For the measurement of objective parameters of movement, we used the mechanography system in Leonardo platform (Novotec, Pforzheim, Germany) which measures forces, calculates through acceleration, the vertical velocity of center of gravity and also using force and velocity it calculates and power of vertical movements. We also calculated the personal power after weight adjustment, i.e., Power/Weight parameter.
Findings: Height was decreased, while BMI and weight increased significantly with age. In groups POST OST, POST HEALTH, RHEUM, all measured parameters were statistically decreased in comparison with group PRE. No statistical significance was found among POST HEALTH and POST OST (postmenopausal) women.
Conclusion & Significance: Muscle mechanography is a novel tool to assess physical performance. It gives to the clinician additional information, while quantitatively assesses muscle function, for planning and evaluating locomotor therapy in women. Muscle mechanography promises to have advantages over currently used tools.
