Objective: Active mattresses are used to prevent, treat and relieve pressure ulcers (PU) by intermittent contact pressure/relief. However, no studies have directly assessed the vascular endothelial response to long-term active mattress use. This study investigated the hypothesis that eight weeks use of an active mattress would lead to improvements in vascular endothelial function in healthy participants. Methods: Physiological parameters of baseline skin temperature (BskT), resting blood flow (RBF) and endothelial function as measured using post-occlusive reactive hyperaemia (PORH), were assessed at baseline (week 0); following eight weeks of sleeping on an active mattress, and after an eight week washout period (at week 16). Results: We recruited 10 healthy participants (four male, age 52.7±8.5 years, six female age 51.8±17.5 years). Following active mattress use RBF, PORH and BskT at the hallux pulp increased by 336%, 197% and 3.5°C, respectively. Mean values increased from 24.3±38.3 perfusion units to 106.0±100.3 perfusion units (p=0.021) and from 13,456±10,225 to 40,252±23,995 perfusion units x seconds (p=0.003) and from 22.9±2.5°C to 26.4±1.9°C (p<0.001), respectively. Conclusion: Active mattress use for eight weeks leads to significant improvements in RBF, PORH, and BskT. These results suggest that active mattress use can improve endothelial function. Future research is required to explore the potential of active mattress use in the treatment and management of diseases and conditions that would benefit from an improved endothelial function.
