Does the Severity of Arm Tremor in Essential Tremor Correlate with Impaired Balance?

Key Points

• Upper limb action tremor severity correlates with both balance confidence and performance-based balance measures.
• A notable connection exists between tremor severity and tandem gait performance, suggesting shared underlying mechanisms.
• Data support a model indicating that both tremors and balance issues may stem from cerebellar dysfunction.
• Findings encourage further exploration of the relationship between balance confidence and motor function in essential tremor.
