Transcranial Electrical Stimulation With Special Waveform for Upper Extremity Rehabilitation for Patients With Stroke
Studienübersicht
Detaillierte Beschreibung
Transcranial direct current stimulation (tDCS) and intermittent theta burst stimulation (iTBS) were both demonstrated to have therapeutic potentials to rapidly induce neuroplastic effects in various rehabilitation training regimens. Recently, the investigators have developed a novel transcranial electrostimulation device that can flexibly output an electrical current with combined tDCS and iTBS waveforms. However, limited studies have determined the therapeutic effects of this special waveform combination on clinical rehabilitation. Herein, the investigators aiming to brain stimulation effects of tDCS-iTBS on upper-limb motor function in chronic stroke patients.
Twenty-four subjects with a chronic stroke were randomly assigned to a real non-invasive brain stimulation (NIBS; subjects received the real tDCS+iTBS output) group or a sham NIBS (subjects received sham tDCS+iTBS output) group. All subjects underwent 1 h treatment of a conventional rehabilitation program (3 days a week for 6 weeks), where a 20-min NIBS intervention was simultaneously applied during conventional rehabilitation. Outcome measures were assessed before and immediately after the intervention period: Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Jebsen-Taylor Hand Function Test (JTT), and Finger-to-Nose Test (FNT).

Intervention / Behandlung |
---|---|
Experimental: tCES & upper extremity rehabilitation
The experiment group will receive tCES combined with upper extremity rehabilitation of affected side.
|
The positions of the lesion side primary motor cortex were defined as C3/C4 according to the international 10-20 system of electroencephalograms.
tCES will be applied for 20 minutes at an intensity of 1.0 -1.5 mA direct current stimulation and a specific-added waveform each time, 3 times a week, lasting for 6 weeks.
|
Schein-Komparator: Sham tCES & upper extremity rehabilitation
The sham control group will receive sham tCES combined with upper extremity rehabilitation of affected side.
|
The positions of the lesion side primary motor cortex were defined as C3/C4 according to the international 10-20 system of electroencephalograms.
Sham tCES will consist of a 5-second ramp up to 1.0-1.5 mA direct current stimulation and a specific-added waveform followed immediately by a 5-second ramp down, no current in the middle 19 minutes 40 seconds, and a ramp-up and ramp-down period during the last 10 seconds.

Was misst die Studie?
Primäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Change from baseline in the Fugl-Meyer Assessment upper extremity scale (FMA-UE) after intervention
Zeitfenster: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
|
The FMA-UE was performed (score ranges from 0 to 66) to assess upper limb motor recovery.
Each movement is estimated by a 3-point scale (0-1-2).
The total score of the FMA-UE is 66, and a higher score indicates that the patient has better movement ability.

Sekundäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Change from baseline in the Jebsen-Taylor Hand Function Test (JTT) after intervention
Zeitfenster: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
|
The JTT assesses hand functions commonly used in activities of daily living.
The subtests are scored according to time taken to complete the task.
Total score is the sum of time taken for each subtest, with shorter times indicating better performance.
|
Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
|
Change from baseline in the Finger to Nose Test after intervention
Zeitfenster: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
|
The Finger to Nose Test assesses coordination of upper-extremity movement.
The number of complete nose-target movements during a 1 min period will be recorded.
|
Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
|
Modified Ashworth scale (MAS) measures
Zeitfenster: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
|
The Modified Ashworth scale (MAS) measures resistance during passive soft-tissue stretching and is used as a simple measure of spasticity
|
Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)
