To study the effectiveness of mindfulness-based meditation in the functional outcome of osteoarthritis knee and perceived stress scores and markers of obesity in postmenopausal women

Abstract

Background: The global burdens of cardiovascular diseases (CVDs) and obesity are rising, producing enormous losses of life and disability-adjusted life-years in both developed and developing nations. Stress is a modifiable risk factor for the development of CVD. Postmenopausal women with osteoarthritis (OA) of knee joint may often report episodes of knee instability limiting their daily activities and this causes an added stress. Aims: To evaluate the effects of mindfulness-based meditation on functional outcome of OA knee and to study the effect of mindfulness-based meditation on perceived stress scores (PSSs) and markers of obesity in postmenopausal women. Materials and Methods: This interventional study was conducted on forty postmenopausal women in a tertiary care hospital of Eastern India after taking institutional ethical clearance and informed consent of the patients. Presumptive stressful life events scale (PSLES) scores and PSSs of the patients were assessed. Patients with PSLES scores more than 200 were included in the study. They were all on nonvegetarian diet and came from the middle socioeconomic class. Patients were randomly allocated into two groups and received either balancing exercises and mindfulness-based meditation (Group A) or balancing exercises (Group B). Patients of both groups were age matched. Body mass index (BMI) and waist/hip ratios were measured. The outcome measures were visual analog scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores. Results: There was no significant difference in age, PSLES and PSS scores, and WOMAC and VAS scores between the two groups before intervention. AGE Group A 62.4 ± 4.16 versus Group B 62.15 ± 3.75, P = 0.85; BMI Group A 26.6 ± 1.97 versus Group B 26.2 ± 1.002, P = 0.41; waist/hip Group A 0.833 ± 0.033 versus Group B 0.832 ± 0.03, P = 0.96; PSLES Group A 296.3 ± 34.95 versus Group B 291.8 ± 25.2, P = 0.65; PSS Group A 33.38.1 ± 1.97 versus Group B 32.8 ± 2.86, P = 0.185. PSS scores (20.75 ± 1.9 vs. 27.1 ± 1.65; P < 0.0001) and waist/hip ratio were significantly less in Group A as compared to Group B following intervention. Group A had significantly lower WOMAC (38.1 ± 4.03 vs. 50.8 ± 3.78; P < 0.0001) and VAS (4.35 ± 0.77 vs. 5.75 ± 0.68; P < 0.0001) scores as compared to Group B after practice of balancing exercises along with mindfulness-based meditation. Waist/hip ratio was significantly less in the group practicing mindfulness-based meditation (Group A) as compared to Group B. Conclusion: The results of the present study indicate that balancing exercises when practiced along with stress relaxation exercises are more effective in improving the functional ability of OA knee in postmenopausal women.
