Physiotherapy based on problem-solving in upper limb function and neuroplasticity in chronic stroke patients: A case...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Clinical Neurology

Background:

• Upper limb recovery is a primary goal in stroke neurorehabilitation.
• Neuroplasticity is crucial for functional recovery, especially in chronic stroke.
• Problem-solving-based physiotherapy may enhance arm function and brain changes.

Purpose of the Study:

• To evaluate the impact of problem-solving physiotherapy on arm function in chronic stroke patients.
• To investigate associated neuroplastic changes using functional magnetic resonance imaging (fMRI).

Main Methods:

• A pre-post test design with 3 chronic stroke patients over 4 weeks.
• fMRI, Action Research Arm Test, Motor Assessment Scale, and Fugl-Meyer Scale were used.
• Intervention involved 50-minute sessions, 5 days/week for 4 weeks.

Main Results:

• All patients demonstrated over 20% improvement in arm function post-intervention.
• Patients showed increased activity in the contralateral precentral area after physiotherapy.
• Baseline fMRI revealed similar motor execution activation in patients and controls, but not during motor imagery.

Conclusions:

• Four weeks of problem-solving physiotherapy effectively promoted arm function recovery and neuroplasticity in chronic stroke.
• The findings suggest this therapy is a promising approach for stroke neurorehabilitation.
• Further research is recommended to confirm the efficacy of this therapeutic strategy.
