Trial Outcomes & Findings for Stability of Motor Output in Aging Adults (NCT NCT00970736)

NCT ID: NCT00970736

Last Updated: 2015-04-08

Results Overview

Cortical sites are stimulated sequentially from the SOLMT in the anterior direction. At each site, 5 pulses of 110% of the MEP threshold obtained at the SOLMT are delivered and recorded. If a site produces no MEP in 3/5 pulses it is considered non-submental. This process is continued until the entire submental representation is surrounded by non-submental responsive sites. The number of sites is used to calculate the area of submental representation. The mean sEMG amplitudes of the submental muscles for each of these sites is then calculated for the mean MEP measure.

PRIMARY outcome

Timeframe: 2 weeks

Population: This data was not analyzed because the study funding, as well as PIs VA affiliation, ended prior to any data analyses.

Cortical sites are stimulated sequentially from the SOLMT in the anterior direction. At each site, 5 pulses of 110% of the MEP threshold obtained at the SOLMT are delivered and recorded. If a site produces no MEP in 3/5 pulses it is considered non-submental. This process is continued until the entire submental representation is surrounded by non-submental responsive sites. The number of sites is used to calculate the area of submental representation. The mean sEMG amplitudes of the submental muscles for each of these sites is then calculated for the mean MEP measure.
