Cognitive-motor interference in people with essential tremor. | LitMetric

AI Article Synopsis

  • The study examines how individuals with Essential Tremor (ET) manage dual tasks, focusing on their ability to combine mobility and cognitive functions during daily activities, which is crucial for preventing falls and maintaining independence.
  • Researchers compared 15 individuals with ET and 15 without ET during a standard and a challenging water-carry timed up-and-go (TUG) test to evaluate how each group handles motor and cognitive tasks simultaneously.
  • Results showed that neither group experienced significant difficulties when performing both tasks at the same time, with both groups prioritizing cognitive tasks, suggesting a need for personalized therapies that address the motor-cognitive challenges specific to those with ET.

Article Abstract

Adapting to different environments throughout daily activities requires flexibility in allocating attention. Compromised dual-tasking can hinder mobility, increase fall risk, and decrease functional independence in patients with essential tremor, who exhibit both mobility and cognitive impairments. We evaluated motor and cognitive dual-task effects and task prioritization in 15 people with Essential Tremor (ET) and 15 age-matched people without ET during a standard and more challenging water-carry TUG. Task-specific interference was evaluated by calculating motor and cognitive dual-task effects, whereas task prioritization was assessed by contrasting the cognitive dual-task effect with the motor dual-task effect. The simultaneous performance of two tasks did not differentially impact motor or cognitive performance in either group, and both groups prioritized cognitive task performance in standard and water-carry TUG assessments. This study enhances our understanding of motor-cognitive interactions in individuals with essential tremor. These insights could lead to patient-centered approaches to therapy to improve functional performance in dynamic daily environments.
