An interventional study of High pulsed magnetic fields in Sensory Disorders, sponsored by Weinberg Medical Physics LLC. Completed at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-10-08.
Sponsored by Weinberg Medical Physics LLC · Not applicable, Interventional, and Basic science
This study is being conducted to improve magnetic resonance imaging (MRI) scans by reducing the time required for imaging. Experience has shown that unpleasant side-effects from magnetic pulses used in MRI (for example, tingling or tapping sensations) can be reduced when the magnetic pulses are shortened. In this study, we will explore whether this effect holds true when very short magnetic pulses are applied.

Exclusion Criteria:
Each subjects will undergo escalating exposure to magnetic field
Device: High pulsed magnetic fields
Magnetic fields will escalate in strength
Also known as: Pulser is custom built by Applied Pulsed Power, Ithaca NY
Degree of Discomfort Under Applied Pulsed Magnetic Fields
Pulsed magnetic fields will be applied a total of forty-eight times to the right hand of each subject. After each time the magnet coil is pulsed, the subject will be asked if he or she notices any sensation (for example, tingling or tapping). Subjects will be asked to rate the sensation from 0 to 4, where 0 means no sensation, 1 means barely-noticeable sensation, 2 means easily noticeable sensation, 3 means unpleasant sensation, and 4 means very unpleasant sensation.
Time frame: Bioeffects will be assessed within the five-minute application of each pulse sequence
