pessimal

/pes'im-l/ (Latin-based antonym for "optimal") Maximally bad. "This is a pessimal situation." Also "pessimise" To make as bad as possible. These words are the obvious Latin-based antonyms for "optimal" and "optimise", but for some reason they do not appear in most English dictionaries, although "pessimise" is listed in the OED.

In the stage of the pessimal working capability, the total power spectra of the EEGs of the participants of the first group differed on the trend level compared to that recorded in the persons of the second and third groups, [F.
The participants of the third group differed from the first in terms of a higher level of coherence of their EEGs for the frontal lobes (frontal and temporal, especially under the conditions of work), and from the second--by a lower level of coherence of EEG for rear (parietal and occipital) regions, moreover both between each other and the latter--with other lobes (especially in the steady wakefulness state with open eyes and the pessimal working capability).
