Objective To analyze the applicability of Berg Balance Scale （BBS） in the balance assessment of Parkinson’s disease （PD） patients with balancing instrument test as the standard， so as to formulate targeted intervention programs accordingly. Methods A total of 186 patients with PD admitted to Department of Neurology and Department of Rehabilitation Medicine， Huashan Hospital， Fudan University from Jan 2020 to Sep 2022 were selected as the research objects. The static balance function of the patients was evaluated by balancing instrument. The balance function parameters were analyzed according to BBS and levodopa equivalent dose. Results The drug dose did not affect the score of balance instrument. There was a good correlation between BBS and balance instrument. The higher the scale score， the lower the balance instrument score （r=-0.333， P<0.001）. There was a positive correlation between levodopa equivalent dose and item 11 of BBS in subjects with BBS total score of 21-40 （r=0.715，P=0.046）. There was a significant negative correlation between levodopa equivalent dose and item 6 of BBS in subjects with BBS total score of 51-56 （r=-0.300， P=0.001）. The number of people who lost the most points in BBS from large to small was item 14 of standing on one leg （134 cases）， item 13 of standing without support with one foot in front （122 cases）， item 11 of turning 360 degrees （75 cases）， item 8 of reaching forward with outstretched arms （70 cases）， and item 12 of placing one feet alternately on a step or a stool （56 cases）. Conclusion In the absence of balancing instrument， BBS has good clinical applicability in the evaluation of PD patients， and some items can be focused on according to the lost points.
