Buerger-Allen Exercises and Peripheral Circulation in Sedentary Office Workers (BAE-CIRC)
Acute Effects of Buerger-Allen Exercises on Lower Extremity Circulatory Parameters in Sedentary Office Workers: A Single-Group Pretest-Posttest Clinical Trial
調査の概要
詳細な説明
Sedentary behavior and prolonged sitting are associated with impaired venous return, reduced peripheral blood flow, endothelial dysfunction, and increased cardiovascular risk. Office workers who remain seated for extended periods may experience lower extremity discomfort, edema, and early circulatory impairment.
Buerger-Allen exercises are position-based therapeutic exercises that involve sequential elevation, dependency, and horizontal rest of the lower limbs. These exercises are designed to promote arterial inflow, facilitate venous return, and enhance tissue perfusion without requiring specialized equipment. Previous studies have demonstrated beneficial effects in patients with peripheral vascular disease and diabetes, but evidence regarding their acute effects in healthy sedentary adults is limited.
This study will use a quasi-experimental single-group pretest-posttest design to investigate the immediate effects of Buerger-Allen exercises on lower extremity circulation in sedentary office workers. A total of 35 participants aged 18 to 45 years will be recruited from Istanbul Gelisim University. All participants will complete a standardized 20-minute Buerger-Allen exercise protocol.
Primary outcome measures will include skin surface temperature assessed with infrared thermometry, capillary refill time, ankle-brachial index, peripheral oxygen saturation, and heart rate. Measurements will be performed at baseline, immediately after the intervention, and 10 minutes after the intervention.
The study is expected to provide evidence regarding the effectiveness of a simple and low-cost physiotherapy intervention for improving peripheral circulation and preventing the adverse vascular effects associated with prolonged sedentary behavior.

|
実験的：Buerger-Allen Exercise Group
Participants will perform a single standardized 20-minute Buerger-Allen exercise session.
Lower extremity circulatory parameters will be assessed before the intervention, immediately after the intervention, and 10 minutes after the intervention.
|
The intervention consists of a standardized Buerger-Allen exercise protocol involving three sequential positions: (1) elevation of the lower limbs above heart level to facilitate venous return, (2) dependency of the lower limbs to promote arterial blood flow, and (3) horizontal supine rest to stabilize circulation.
The complete exercise session lasts approximately 20 minutes and is performed once.
Lower extremity circulatory parameters are assessed at baseline, immediately after the intervention, and 10 minutes after the intervention.

メジャーの説明 |
時間枠 |
|---|---|---|
|
Skin Surface Temperature
時間枠：Baseline, Immediately After Intervention, and 10 Minutes After Intervention
|
Skin surface temperature measured with an infrared thermometer in degrees Celsius (°C).
Higher values indicate increased peripheral blood flow and tissue perfusion.
|
Baseline, Immediately After Intervention, and 10 Minutes After Intervention
|
|
Capillary Refill Time
時間枠：Baseline, Immediately After Intervention, and 10 Minutes After Intervention
|
Capillary refill time measured in seconds.
Shorter times indicate improved peripheral microcirculation and tissue perfusion.

Ankle-Brachial Index (ABI)
時間枠：Baseline, Immediately After Intervention, and 10 Minutes After Intervention
|
Ratio of ankle to brachial systolic blood pressure used to assess lower extremity arterial circulation.
Higher values within the normal range indicate better arterial perfusion.
|
Baseline, Immediately After Intervention, and 10 Minutes After Intervention

Peripheral Oxygen Saturation (SpO₂)
時間枠：Baseline, Immediately After Intervention, and 10 Minutes After Intervention
|
Oxygen saturation measured by pulse oximetry and expressed as a percentage (%).
Higher values indicate improved peripheral oxygenation.
