Abstract:
OBJECTIVE:This pilot study aims to determine the effect of the Revitive™ footplate neuromuscular electrical stimulation device on venous and arterial haemodynamic changes in healthy individuals. METHOD:The blood flow (cc/min) and time averaged mean velocity (cm/s) of the superficial femoral vein and artery were measured using ultrasound at baseline, 15 min during, and immediately after cessation of the 30 min stimulation cycle. Data were analysed using the Wilcoxon matched-pairs signed rank test. RESULTS:Venous and arterial duplex ultrasound haemodynamic measurements were taken in 10 and 20 healthy volunteers, respectively. Mean age 38.7 (range 21-64), ankle brachial pressure index 0.9-1.0. At 15 min, there was a significant increase in venous median blood flow (88.3 cc/min, p = 0.014) and an increase in time averaged mean velocity (1.13 cm/s, p = 0.065) compared to baseline. Similarly, there was a significant increase in arterial median blood flow (38.7 cc/min, p < 0.0001) and time averaged mean velocity (2.21 cm/s, p = 0.0003) at 15 min compared to baseline. There was no significant difference in venous or arterial measurements compared to baseline after stimulation cessation. CONCLUSIONS:Blood flow and time averaged mean velocity increased during neuromuscular electrical stimulation but returned to baseline once stimulation had stopped. By improving blood flow, neuromuscular electrical stimulation has the ability to enhance venous return, counteract venous stasis and improve limb arterial inflow.
