SECONDARY outcome

Timeframe: Day 1

Population: All participants that completed Cogstate cognitive function testing

Cogstate computerised cognitive function testing. A global T-score is a composite measure determined by the arithmetric mean of 8 test scores covering the following cognitive domains: psychomotor function, visual learning, working memory, executive function, emotional recognition, verbal learning, attention and verbal memory. Raw scores were converted to a standardised T score using age adjusted normative data (mean 50; standard deviation 10). Higher scores are interpreted as 'better' cognitive function.

SECONDARY outcome

Timeframe: Day 1

Population: All subjects who completed full Conditioned Pain Modulation protocol

Conditioned Pain Modulation (CPM) efficiency to protocol using a cold noxious stimulus. The CPM efficiency is calculated as the pressure pain threshold (measured with an algometer on the forearm) during the noxious conditioning stimulus minus the pressure pain threshold prior to conditioning stimulus.
