Assessing the impact of physical activity on bone density, cardiopulmonary function, and metabolic health in stroke survivors.

Abstract

Stroke survivors often face motor impairments leading to decreased physical activity, which can, in turn, result in secondary health-related issues like cardiovascular and pulmonary impairment and osteoporosis. This research finds out the impact of physical activity on bone mineral density, cardiopulmonary health, and metabolic status in stroke survivors. The goal is to generate knowledge to inform rehabilitation strategies, emphasizing the significant role of regular exercise in enhancing the health of individuals recovering from stroke. This study was conducted using a cross-sectional study design, and involved 100 stroke survivors selected through stratified random sampling. Physical activity was measured using the validated Stroke-Specific Physical Activity Questionnaire. Health outcomes were assessed through various means: bone mineral density via the OSTEOKJ3000 ultrasonic bone densitometer; resting heart rate and blood pressure via an automated monitor; lipid profiles through the CardioChek PA analyzer; Hb1Ac levels via the A1CNow + System; and respiratory parameters through a spirometer. Statistical analysis revealed bone mineral density is positively correlated with physical activity (R = 0.53, P < .001). Additionally, an association was found between physical activity and improved cardiopulmonary function (resting heart rate r = -0.45, P < .001; forced expiratory volume in one second R = 0.30, P = .0023; forced vital capacity R = 0.28, P = .0041). Moreover, higher physical activity levels correlated with lower low-density lipoprotein cholesterol levels (r = -0.35, P = .0007), higher high-density lipoprotein cholesterol levels (R = 0.33, P = .0012), and better glycaemic control (HbA1c r = -0.40, P = .0002). This study highlights the significant benefits of physical activity for stroke survivors, showing positive impacts on bone density, cardiopulmonary function, and metabolic health. It underscores the need to include regular exercise in rehabilitation strategies to mitigate secondary health complications and enhance the overall health of stroke survivors. Future research should continue investigating the potential benefits of physical activity in this population.
