The use of motor learning and neural plasticity in rehabilitation for ataxic hemiparesis: A case report

Background and Purpose: Although the principles of neural plasticity for stroke rehabilitation are well established, specific intervention plans for patients with ataxia following a lacunar infarct are not well described. The purpose of this case report is to describe the intervention program for a patient with ataxic hemiparesis based on principles of motor learning and neural plasticity.
Case Description: An 83-year-old, socially active male presented to the emergency department with right-sided upper extremity weakness and ataxia. The patient’s acute hospital course included 4 days in a stoke unit, followed by 13 days in inpatient rehabilitation.
Intervention: A 3-phase graded mobility and coordination plan was used during inpatient rehabilitation. Interventions included function-based training with repeated ambulation, coordination activities for the upper and lower extremities, and strengthening to help the patient achieve his goal of walking “without gait deviations.” The concepts of motor learning and neural plasticity were utilized for timing and feedback on patient errors when implementing this novel program.
Outcomes: The patient’s level of assistance for mobility and activities of daily living improved from minimal assistance to modified independence without use of an assistive device. The Dynamic Gait Index score improved from 16/24 to 20/24 suggesting a decreased fall risk.
Discussion: This case report describes a novel intervention strategy for a patient with ataxia following a lacunar stroke. The application of the principles of neural plasticity and motor learning was the foundation for a function-based plan of care.
