Previous studies on SCD have found it to be particularly time efficient with bouts as short as 1 minute reducing PBG following a glucose challenge and mixed meal,8,9 bouts as short as 3 minutes reducing insulin after a glucose challenge,12 and bouts as short as 10 minutes improving insulin resistance after an oral glucose tolerance test (OGTT) glucose challenge when performed at a self-selected, low to moderate intensity.12 Here, INS is linked to Schnyder corneal dystrophy.
