NCT02821884

Brief Summary

Transcranial direct current stimulation (tDCS) has been shown not only to improve motor function but also increase cortical excitability and neural plasticity. Several studies demonstrated that the combination of tDCS and different treatments are more effective than a single tDCS alone. However, the effects of combination tDCS and neuromuscular electrical stimulation (NMES) on upper extremity motor recovery in patients with stroke have not yet been investigated. Taking into consideration the safety and feasibility of new medical technology, recruitment of healthy subjects as a pilot study. And then recruit the stroke patients to investigate the effects for the combination of tDCS and NMES on upper extremity motor recovery in stroke.

Outcome Measures

Primary Outcomes (1)

  • Movement performance assessment

    Movement performance assessment by clinical motor assessment scales in upper extremity executed by qualified physiotherapy in 3 groups.

    Change from baseline motor performance at 3 weeks, 1 month and 6 months.

Secondary Outcomes (1)

  • Mapping of brain cortex

    Change from baseline motor performance at 3 weeks, 1 month and 6 months.

Study Arms (3)

Combination of tDCS and NMES

EXPERIMENTAL

Both tDCS and NMES conduct simultaneously for 30 minutes.

Device: Combination of tDCS and NMES

Combination of tDCS and sham NMES

ACTIVE COMPARATOR

Both tDCS and sham NMES conduct simultaneously for 30 minutes. Sham NMES electrodes are placed away from all motor points, and the patients receive cutaneous stimulation just above the sensory threshold without motor activation.

Device: Combination of tDCS and sham NMES

Combination of sham tDCS and sham NMES

SHAM COMPARATOR

Both sham tDCS and sham NMES conduct simultaneously for 30 minutes. Shame tDCS is started in a ramp-like fashion but fade out slowly after 30 seconds. Sham NMES electrodes are placed away from all motor points, and the patients receive cutaneous stimulation just above the sensory threshold without motor activation.

Device: Combination of sham tDCS and sham NMES

Interventions

Both tDCS and NMES conduct simultaneously for 30 minutes. The anodal electrode of tDCS is placed on the scalp site corresponding to primary motor cortex (M1) of the hemisphere affected by stroke. The cathodal electrode of tDCS is placed on the scalp site corresponding to unaffected primary motor cortex. The current is initially increased in a ramp-like fashion over 30 seconds until reaching 2 mA and is decreased ramp-like fashion over 30 seconds until reaching 0 mA. The NMES electrodes are placed over the following muscle: extensor digitorum communis, extensor carpi radialis to produce wrist and hand extension. The settings for the NMES is frequency at 50 Hz, pulse width of 200μs,duty cycle of 10 seconds on and 10 seconds off,current amplitude is adjusted to patients comfort (10-20mA).

Combination of tDCS and NMES

Both tDCS and sham NMES conduct simultaneously for 30 minutes. The anodal electrode of tDCS is placed on the scalp site corresponding to primary motor cortex (M1) of the hemisphere affected by stroke. The cathodal electrode of tDCS is placed on the scalp site corresponding to unaffected primary motor cortex. The current is initially increased in a ramp-like fashion over 30 seconds until reaching 2 mA and is decreased ramp-like fashion over 30 seconds until reaching 0 mA. Sham NMES electrodes are placed away from all extensor digitorum communis, extensor carpi radialis motor points, and the patients receive cutaneous stimulation just above the sensory threshold without motor activation(wrist extension).

Combination of tDCS and sham NMES

Both sham tDCS and sham NMES conduct simultaneously for 30 minutes. Sham tDCS electrodes are placed in the same position on patients receiving the sham stimulation. Just like during real tDCS, stimulation is started in a ramp-like fashion but fade out slowly after 30 seconds. Sham NMES electrodes are placed away from all extensor digitorum communis, extensor carpi radialis motor points, and the patients receive cutaneous stimulation just above the sensory threshold without motor activation(wrist extension).
