Who this trial is looking for
This trial is looking for older adults aged 65 to 85 who can perform a treatment called Remote Ischaemic Conditioning (RIC) at home. Participants will receive RIC or a placebo for 6 weeks and attend two visits to measure their vascular health.

Answer a few quick questions to see if you may meet the eligibility requirements.
Remote Ischaemic Conditioning (RIC) is the process of inducing short periods of ischaemia in a limb with the aim of improving vascular health systemically. Recent findings have demonsatrated efficacy in a variety of clinical settings. However, the ideal protocol of RIC \[dose\] is unknown. Dynamic Cerebral Autoregulation (dCA) has been shown to increase in response to RIC.

Remote Ischaemic Conditioning (RIC) is the process of inducing short periods of ischaemia in a limb with the aim of improving vascular health systemically. Recent findings have demonsatrated efficacy in a variety of clinical settings. However, the ideal protocol of RIC \[dose\] is unknown. Dynamic Cerebral Autoregulation (dCA) has been shown to increase in response to RIC.
The goal of this trial is to study whether an increase in RIC protocol intensity results in a larger effect on biomarkers of vascular health such as dCA.
Participants shall:
Receive RIC daily, RIC thrice weekly or sham RIC thrice weekly for 6 weeks Visit the School of Medicine at baseline and at 6 weeks for measurement of biomarkers of vascular health including blood pressure, indices od dCA and blood plasma samples
