Multiple linear regression was used, and the basis for single-factor variables entering the regression model was P < 0.05. ΔMDS-UPDRS III: Changes in MDSUPDRS III after MIRT; adependent variable: ΔMDS-UPDRS III; #P < 0.05, vs. PIGD group. MDS-UPDRS III: Movement Disorder Society-Unified PD Rating Scales III; PIGD: postural instability/gait difficulty; TD: tremor dominant.
