The Investigation of Therapeutic Effect and Platelet Activity After ILIB for Ischemic Stroke Patient
- Conditions
- Ischemic Stroke
- Interventions
- Device: Intravascular laser irradiation of blood
- Registration Number
- NCT05456750
- Lead Sponsor
- Tri-Service General Hospital
- Brief Summary
The aim of our study is to therapeutic effect and platelet activity after intravenous laser irradiation of blood for ischemic stroke patient
- Detailed Description
Background : This research is designed through randomization, control, and double-blind trial to explore the clinical effectiveness of intravenous laser irradiation of blood for ischemic stroke patient; The research will further explore the changes in platelet activity after treatment. The light accelerates blood and cells circulation in the human body, so that protein molecular structure would promote changes. Pain control is indicated in such treatment, but still lacking evidence of neurological symptoms and functional improvement.
Purpose:This research is designed through randomization, control, and double-blind trial to therapeutic effect and platelet activity after intravenous laser irradiation of blood for ischemic stroke patient. Furthermore, to establish a new way of clinical rehabilitation therapy.
Method: The investigators plan to recruit 20 patients who are between the ages of 20 to 80 years old. The participants are required to have clear conscious and be able to communicate. The patient with mild to moderate stroke ( NIHSS=1-15), which onset between one month to 2 years will be included. The treatment group will receive an intravenous helium-neon laser phototherapy. A vein indwelling needle will be placed in their veins located in the upper elbow, and the laser fiber catheter will be introduced through the indwelling cannula. The power is set between 2.5 \~ 3.0Mw, 60 minutes each time, once a day for five consecutive days each week, for 2 weeks (total 10 times in one course). The steps for the control group are the same, except that the output power is adjusted to zero intensity. This plan will be explained to the patient in detail during the outpatient visit and patients will sign the consent form upon agreement. Before intravenous laser irradiation, three days, one month, and three months after the therapy, 20 ml of autologous peripheral venous blood need to be drawn for basic blood tests and platelet activity tests. At the same time, the clinical functions of patients will be evaluated, including NIHSS, mRS and Stroke Impact Scale (SIS).

Group Intervention Description treatment group Intravascular laser irradiation of blood The treatment group receive an intravenous helium-neon laser phototherapy. A vein indwelling needle will be placed in their veins located in the upper elbow, and the laser fiber catheter will be introduced through the indwelling cannula. The laser power is set between 2.5 \~ 3.0Mw, 60 minutes each time, once a day for five consecutive days each week, for 2 weeks (total 10 times in one course) control group Intravascular laser irradiation of blood The steps for the control group are the same as the treatment group, except that the output power is adjusted to zero intensity.
- Primary Outcome Measures
Name Time Method Modified Rankin Scale (mRS) 3 month The Modified Rankin Scale (mRS) is used to measure the degree of disability or dependence in the daily activities in patients who have had a stroke 0: No symptoms at all
1. No significant disability despite symptoms; able to carry out all usual duties and activities
2. Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance
3. Moderate disability; requiring some help, but able to walk without assistance
4. Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance
5. Severe disability; bedridden, incontinent and requiring constant nursing care and attention
6. Dead Measure before intravenous laser irradiation, three days, one month, and three months after the therapy.Stroke Impact Scale(SIS) 3 month The Stroke Impact Scale (SIS) is a newly developed comprehensive outcome measure consists of items measuring 8 domains- strength, hand function, activities of daily living (ADL) and instrumental ADL, mobility, communication, emotion, memory and thinking, and participation. It was based on feedback from patients and their caregivers. Measure before intravenous laser irradiation, three days, one month, and three months after the therapy.
National Institutes of Health Stroke Scale (NIHSS) 3 month NIHSS is a measure of the severity of symptoms associated with ischemic stroke and is used as a quantitative measure of neurological deficit post stroke. NIHSS score is composed of 11 items, including consciousness, eye movement, visual fields, muscle power of four limbs, limbs ataxia, sensation, language, dysarthria and extinction. Each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. Total score are between 0-42.
Measure before intravenous laser irradiation, three days, one month, and three months after the therapy.
- Secondary Outcome Measures
Name Time Method Platelet activity 3 month Platelet aggregation test. Measure before intravenous laser irradiation, three days, one month, and three months after the therapy.
