By analyzing the clinical data, tremor analysis results, and final diagnoses of patients with tremor, this study aims to clarify the significance of tremor analysis and provide assistance for clinicians. Methods: Patients who underwent tremor analysis in the electromyography laboratory of the Neurology Department at Beijing Friendship Hospital from January 2022 to January 2024 were screened according to inclusion and exclusion criteria. Clinical data and tremor analysis results of enrolled patients were summarized. Comparisons were made between the clinical data and tremor analysis results of two groups--essential tremor (ET) and Parkinson's disease (PD)--while clinical and tremor analysis findings for other tremor patients were also summarized. Results: A total of 192 patients were enrolled in this study, including 103 cases of essential tremor (53.6% ), 74 cases of Parkinson's disease (38.5% ), 4 cases of dystonia (2.1% ), 3 cases of peripheral neuropathy-associated tremor (1.6% ), 3 cases of orthostatic tremor (1.6% ), 4 cases of enhanced physiological tremor (2.1%), and 1 case of multiple system atrophy (0.5%). Comparisons between ET and PD groups revealed statistically significant differences in age, disease duration, family history, onset site, tremor pattern, contraction form, and presence of harmonic components (P<0.05). Significant differences in tremor frequency were observed between the two groups under resting, postural, intentional, and 1 kg load conditions (P<0.05), while no significant differences in tremor amplitude were found (P>0.05). Conclusion: This real-world study on tremor analysis demonstrates the complexity and diversity of tremor-related disorders. Tremor analysis is a valuable diagnostic tool, particularly in differentiating between ET and PD.
