Combined therapy with contralateral controlled functional electrical stimulation and transcranial direct current...

Area of Science:

• Neurorehabilitation
• Stroke Recovery
• Neuromodulation Techniques

Background:

• Early post-stroke hand dysfunction significantly impacts patient independence and quality of life.
• Traditional therapies offer limited recovery for severe hand impairments.
• Novel therapeutic strategies are needed to enhance motor function after stroke.

Purpose of the Study:

• To evaluate the clinical efficacy of combining contralateral controlled functional electrical stimulation (CCFES) with transcranial direct current stimulation (tDCS) for treating early post-stroke hand dysfunction.
• To compare the effectiveness of CCFES + tDCS versus tDCS alone and traditional therapy.

Main Methods:

• Ninety patients with early post-stroke hand dysfunction were randomized into three groups: control (traditional therapy), experimental group 1 (tDCS + standard care), and experimental group 2 (CCFES + tDCS + standard care).
• Assessments included Fugl-Meyer Assessment for Upper Extremity (FMA-UE), Functional Test for the Hemiplegic Upper Extremity-Hong Kong (FTHUE-HK), Modified Barthel Index (MBI), Brunnstrom stages, Motor Assessment Scale (MAS), and surface electromyography (sEMG).

Main Results:

• All groups showed significant improvements post-treatment (p < 0.05).
• Experimental group 1 (tDCS) demonstrated greater improvements than the control group.
• Experimental group 2 (CCFES + tDCS) exhibited superior outcomes compared to both the control and experimental group 1 (p < 0.05).

Conclusions:

• The combination of CCFES and tDCS offers a substantial benefit for improving hand function in early stroke patients.
• CCFES combined with tDCS is more effective than tDCS therapy alone in enhancing motor recovery.
• This combined neuromodulation approach represents a promising strategy for stroke rehabilitation.
