Intervention / Treatment
Detailed Description
Nowadays, stroke is the third cause of death in developing countries after coronary heart disease and cancer. Worldwide, 3 million women and 2.5 million men were killed by the stroke every year. In Thailand, stroke is the first leading cause of death. In every 2 minutes, Thai population have occurred at least one new stroke case.
Over six months after stroke onset or chronic phase, long-term disability occurred when patients did not continuously receive appropriate intervention. Motor disability is the most limiting factor influencing activities in daily life, such as upper and lower limb motor functions, and gait disturbance, which could in turn leading to long-term disability. Especially, affected arm remains malfunction in half of chronic stroke patients. The multidisciplinary rehabilitation has been provided for chronic stroke patients to reduce burden of caregivers and to improve patients' well-being. Besides, many patients with chronic stroke who live in community could not access the hospital or health care center because of inconvenient transportation as well as limited support by the family.
It past twenty years, transcranial direct current stimulation (tDCS) has been introduced as is non-invasive brain stimulation (NIBS) that can use in rehabilitation. There are several studies shown that tDCS can change cortical excitability in the brain and consider as an additional therapy to improve motor function in stroke patients. Moreover, the tDCS is portable, cost effective, safety to use and can be self-administered might benefit for patients in residence. In fact, imbalance of interhemispheric inhibition (IHI) occurred after stroke by neuronal excitability decreased in the lesioned hemisphere and increased in the non-lesioned hemisphere. The tDCS delivered weak direct current via two electrodes as anodal and cathodal. The effect of cathodal electrode can decrease excitability and increase excitability by anodal electrode. Furthermore, both electrodes were applied on the two hemisphere in the same period for expect the results of two electrode called dual tDCS.
Current evidence indicated that the 4-week anodal tDCS combined transcranial direct current stimulation (tDCS) with robotic training could improve motor function in chronic stroke patients. Nevertheless, this intervention program is a hospital-based intervention, which would limit the generalization to patients who live in community. Previous study showed that 4-week anodal tDCS combined with exercise could improve upper and lower limb motor functions in chronic stroke patients. However, there is no evidence indicate that 4-week home-based tDCS combined with exercise have been improved upper and lower limb motor functions in chronic stroke patients in residence.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Dual-tDCS & home program exercise
Dual transcranial direct current stimulation (tDCS) will be applied over C3-C4 by using a reference to the international 10-20 electrode placement system for EEG electrode placement.
The current intensity will be 2 mA, delivered for 20 minutes before the home-based exercise program by themselves and/or caregiver.
Anodal electrode will be applied over the M1 of the affected hemisphere, while the cathodal electrode will be applied over the M1 of the non-lesioned.
In all sessions of intervention at participant's resident, the investigator will supervise the processes of setting tDCS and exercise in all sessions (total 12 sessions, 3 days per week for 4 weeks).
|
Dual/ Sham tDCS will be applied in 2 mA, 20 mins before the home-based exercise program in 3 times per week for 4 weeks (12 sessions)
|
Sham Comparator: Sham-tDCS & home program exercise
Sham transcranial direct current stimulation (tDCS) will be applied over C3-C4 by using a reference to the international 10-20 electrode placement system for EEG electrode placement.
The current intensity will be 2 mA, delivered only 30 seconds before the home-based exercise program by themselves and/or caregiver.
Anodal electrode will be applied over the M1 of the affected hemisphere, while the cathodal electrode will be applied over the M1 of the non-lesioned.
In all sessions of intervention at participant's resident, the investigator will supervise the processes of setting tDCS and exercise in all sessions (total 12 sessions, 3 days per week for 4 weeks).
