1. A method for reducing clinical presentations of a neurological movement disorder in a subject, the method comprising:
- (i) administering a first deep brain stimulus train to the subject;
(ii) measuring cortical local field potentials (LFPs) from a surface of the subject'"'"'s primary motor cortex using at least one electrode, wherein the at least one electrode is located at a position corresponding to an arm area of primary motor cortex M1;
(iii) calculating, with a processor, a modulation index for synchronization of brain rhythms in the LFPs, wherein the synchronization of brain rhythms in the LFPs comprises synchronization of phase of beta rhythm and amplitude of gamma activity; and
(iv) administering a second deep brain stimulus train to the subject when the calculated modulation index is outside of a predefined threshold range;
wherein steps (i)-(iv) are continued in a manner effective to reduce the clinical presentations of the neurological movement disorder.

Abstract
The present disclosure provides methods for reducing the clinical presentations of a neurological movement disorder in a subject. Aspects of the methods include measuring cortical local field potentials (LFPs) from the subject'"'"'s brain, calculating a modulation index related to brain synchronization from the LFPs, and administering deep brain stimulation to the subject if the calculated modulation index is outside of a threshold range. Also provided are devices, systems, and kits that may be used in practicing the subject methods.
