Background: Freezing of gait (FOG) is a major disabling symptom that affects the quality of life of patients with Parkinson’s disease (PD). To date, notions about the effects of subthalamic deep brain stimulation (STN-DBS) on FOG remain controversial. Therefore, we developed a prediction model based on the influence of bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) on FOG in patients with PD. Methods: We collected data from 104 PD participants with FOG who underwent STN-DBS at Xuanwu Hospital between September 2017 and June 2022. The patients were divided into training set (70%; n = 68) and validation set (30%; n = 36). The selected characteristics in the LASSO regression were used in multivariate logistic regression to build the prediction model. Receiver operating characteristic (ROC) curves for the training and validation sets were constructed to verify the model efficiency. Results: Independent variables in the prediction model included Unified Parkinson’s Disease Rating Scale II (UPDRSII), UPDRSIV, Legs rigidity, Montreal Cognitive Assessment (MoCA) score, and Mini Mental State Examination (MMSE) score. The prediction model formula is as follows: Logit(y) = -1.0043 + 0.159 × UPDRSII + 0.030 × UPDRSIV - 1.726 × Legs rigidity + 0.121 × MoCA + 0.036 × MMSE. We draw the ROC curve of the training and validation sets to validate the model, the area under the ROC curve (AUC) of the internal validation was 0.869 (95% confidence interval [CI]: 0.771-0.967) and the AUC of external validation was 0.845 (95%CI:0.6526-1), the calibration plots showed good calibration. Conclusions: The model we developed can effectively assist clinicians in preoperatively assessing the efficacy of bilateral subthalamic nucleus deep brain stimulation for freezing of gait in Parkinson's disease patients, enabling the formulation of personalized treatment plans and better improving patient outcomes.
