ibotenic acid has been researched along with Myocardial Ischemia in 1 studies
Ibotenic Acid: A neurotoxic isoxazole (similar to KAINIC ACID and MUSCIMOL) found in AMANITA mushrooms. It causes motor depression, ataxia, and changes in mood, perceptions and feelings, and is a potent excitatory amino acid agonist.
Myocardial Ischemia: A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).

Digital pain rating system that scores patient's subjective pain rating from 0 to 10; with greater number indicating progressively worsening pain. NPRS were measured at baseline (visit1), and at each follow ups visits at visit 2, 3 and 4. Visit 2 and 4 captured post treatment (either 1000 Hz or standard stimulation depending on the randomization) results, and visit 3 captured NPRS after the wash off from the spinal cord stimulation. (NCT02265848)
Timeframe: Baseline (visit 1), and at each follow up visits (visits 2, 3, and 4)

ODI is a outcome metrics that is design to assess the severity of disability based on 10 activity categories. ODI is based on 0 to 100% scale, where larger percentage implies worse disability. (There are 5 categories: 0-20%: Minimal disability, 21-40%: Moderate disability, 41-60%: Severe disability, 61-80%: Crippled. 81-100%: Either bed bound or exaggerating symptoms). ODI were measured at baseline (visit1), and at each follow ups visits at visit 2, 3 and 4. Visit 2 and 4 captured post treatment (either 1000 Hz or standard stimulation depending on the randomization) results, and visit 3 captured NPRS after the wash off from the spinal cord stimulation. (NCT02265848)

PGIC is a 7-point scale that requires study subjects to rate the severity of their illness or medical condition after a specific treatment. 1: No change, 2: Almost the same, 3: A little better, 4: Somewhat better, 5: Moderately better, 6: Better, 7: A great deal better. Study subjects were asked to report their impression of changes at baseline visit, visit 2 through 4. (NCT02265848)
Timeframe: Baseline (visit 1), and at each follow up visits (visits 2, 3, and 4)

At the conclusion of the study, subjects were asked to report which spinal cord stimulation modes they preferred. Subjects were presented with two boxes (1000 Hz. stimulation and Standard stimulation) and asked to check one. (NCT02265848)
