Effects of L-DOPA on motor symptoms. Comparison of MDS-UPDRS Part III scores and its subscores (“upper limb rigidity on the recorded side”, “upper limb bradykinesia on the recorded side” and “upper limb tremor on the recorded side”) between “PD without L-DOPA” (dark grey bars) and “PD with L-DOPA” (light grey bars). The y-axis indicates MDS-UPDRS score. Paired t-test showed significant differences in MDS-UPDRS Part III score, “upper limb rigidity on the recorded side” and “upper limb bradykinesia on the recorded side”.
