Background And Purpose:
Background and purpose – To evaluate the efficacy of the combined therapy of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) and dopaminergic medication on balance and mobility in patients with Parkinson’s disease (PD).
.Methods:
Eighteen PD patients under bilateral STN-DBS stimulation therapy, were enrolled in this study. Unified Parkinson’s Disease Rating Scale (UPDRS) was applied to assess the patients’ clinical characteristics. UPDRS part III postural instability/gait disorder (PIGD) scores (sum of items 3.9-3.13) and UPDRS part III postural stability item (item 3.12) were calculated separately. Patients were evaluated with Berg Balance Scale (BBS), Mini-Balance Evaluation Systems Test (Mini-BESTest), Timed Up and Go (TUG) test, dual-task TUG test, and Forward Functional Reach (FFR) Test in two conditions: Stimulation-ON (stim-ON)/Medication-ON (Med-ON) and Stimulation-OFF (Stim-OFF)/Med-ON.
.Results:
The mean age of patients was 59.5±9.1 (R: 41-71) years. The UPDRS part III total score and PIGD subsection score significantly improved after stimulation (p=0.001), but the postural instability item of the UPDRS part III did not change significantly (p=0.1). There were no significant differences between the Stim-ON/Med-ON and Stim-OFF/Med-ON conditions, in terms of total Mini-BESTest total scores, total BBS score, FFR test score (p>0.05 for all of them). TUG test was significantly improved in the Stim-ON/Med-ON condition compared to Stim-OFF/Med-ON condition (p=0.03), but DT-TUG test did not change (p=0.1).
.Conclusion:
Combined bilateral STN-DBS and dopaminergic medication therapy had an additional improvement on motor symptoms and mobility performance, but not on balance and dual-task mobility.

Article Synopsis
- The study investigates how subthalamic nucleus deep brain stimulation (STN-DBS) surgery affects cognitive aspects of motor control in people with Parkinson's disease (PD) over time.
- Researchers compared participants' saccade latency and reach reaction time before surgery and about 8 months after surgery while off medication and stimulation.
- Results showed that both saccade latency and reach reaction time significantly worsened post-surgery, suggesting negative long-term cognitive impacts from the surgery.

Purpose: The outcomes of motor and non-motor features of Parkinson's disease (PD) following DBS vary among its subtypes. We tested whether pre-operative motor subtyping using the modified Tremor/PIGD ratio, could indicate the short-term motor, non-motor and quality of life (QOL) outcomes of STN-DBS.
Method: In this prospective study, 39 consecutive STN-DBS cases were assessed in Drug-OFF state before surgery and subtyped using the ratio of tremor and PIGD scores (T/P ratio).

Article Synopsis
- Parkinson's disease (PD) is a movement disorder linked to the degeneration of dopamine-producing neurons, and treatments like Levodopa (L-dopa) and Subthalamic Deep Brain Stimulation (STN-DBS) have distinct effects on brain activity that need further study.
- In a study involving 21 PD patients on L-dopa and 11 patients with STN-DBS, researchers used Magnetoencephalogram (MEG) data to analyze how these treatments impacted brain state dynamics through a statistical method called the Time-delay embedded Hidden Markov Model (TDE-HMM).
- Results showed that L-dopa enhanced motor state and beta wave activity in the brain, correlating
