Repetitive transcranial magnetic stimulation combined with stepwise task orientation for upper limb function in...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Neurology

Background:

• Traditional stroke rehabilitation lacks a strong neuroscience foundation.
• Current methods focus on peripheral motor recovery, not brain-centred models.
• Objective biomarkers are needed for assessing neurobiological changes.

Purpose of the Study:

• To investigate the efficacy of combining repetitive transcranial magnetic stimulation (rTMS) with task-oriented training for chronic stroke patients.
• To evaluate neurobiological and functional improvements using objective assessments.
• To compare this approach against sham rTMS and conventional rehabilitation.

Main Methods:

• 87 chronic stroke patients were divided into three groups: rTMS + task-oriented training, sham rTMS + task-oriented training, and conventional rehabilitation + sham rTMS.
• Intervention duration was four weeks.
• Comprehensive neurobiological and functional assessments were conducted.

Main Results:

• The group receiving rTMS and task-oriented training showed significant improvements in motor function, activities of daily living, and muscle tone.
• Neuroimaging indicated increased motor network connectivity and normalized interhemispheric balance in this group.
• Control groups demonstrated less pronounced improvements.

Conclusions:

• Combined rTMS and task-oriented training is an effective strategy for stroke rehabilitation.
• This brain-centred approach offers superior outcomes compared to conventional methods.
• The findings support the integration of neurostimulation techniques into rehabilitation protocols.
