	TBS	TGS	TTS	TUG	BBS	FR
UPDRS (III)	−.804 (<.001)	−.635 (.003)	−.731 (<.001)	.701 (.001)	−.657 (.002)	−.229 (.332)

Note: TBS: Tinetti's balance score, TGS: Tinetti's gait score, TTS: Tinetti's total score, TUG: Time Up & Go, BBS: Berg Balance Scale, FR: Functional Reach, and PIGD: postural instability and gait disturbance. Significant P values are marked in bold.
