Buerger-Allen Exercises and Peripheral Circulation in Sedentary Office Workers

Condition(s) studied

Investigational drug(s) / intervention(s)

Buerger-Allen Exercise Program: 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.

Study summary

This study aims to evaluate the acute effects of Buerger-Allen exercises on lower extremity circulation in sedentary office workers. Prolonged sitting is associated with reduced venous return, impaired peripheral circulation, and endothelial dysfunction. Buerger-Allen exercises are simple position-based exercises designed to enhance arterial blood flow, venous return, and tissue perfusion. Thirty-five healthy sedentary adults aged 18 to 45 years will participate in this single-group pretest-posttest clinical trial. Skin surface temperature, capillary refill time, ankle-brachial index, peripheral oxygen saturation, and heart rate will be measured before and after a single 20-minute exercise session. The findings may support the use of Buerger-Allen exercises as a practical, low-cost physiotherapy strategy to improve peripheral circulation and reduce the adverse vascular effects of prolonged sitting.

Eligibility

Primary outcome measure(s)

• Skin Surface Temperature — 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.
• Capillary Refill Time — Baseline, Immediately After Intervention, and 10 Minutes After Intervention
  Capillary refill time measured in seconds. Shorter times indicate improved peripheral microcirculation and tissue perfusion.
