Investigation of Huatuo Zaizao Pill in Treating Phlegm and Blood-stasis Blocking Collaterals Pattern of Ischemic Stroke Patients: Study Protocol for a Randomized Controlled Trial

This study is aiming to evaluate the efficacy and safety of Huatuo Zaizao pill in ischemic stroke patients who diagnosed as the phlegm and blood-stasis blocking collaterals syndrome in TCM. A total of 80 subjects will be randomly assigned to Huatuo Zaizao pill group or the control group.

This is a prospective, randomized controlled clinical trial. Eighty patients with phlegm and blood stasis block syndrome of ischemic stroke were randomly assigned to Hua Hua reconstruction group or control group at a ratio of 1:1. The treatment period is 12 weeks. The purpose is to evaluate its efficacy and safety, provide an objective basis for precise treatment of traditional Chinese medicine, and improve clinical efficacy. The main result is the changes of NIHSS, Fugl-Meyer, and MAS 90 days after taking the drug. The secondary result is the change in ADL and TCM symptom scale (CM-SS).

Participants are randomly and evenly assigned to 2 groups using block randomization.Random numbers are generated by the stratified random method using the Statistical Analysis Software （SAS） statistical software and assigned by an independent statistician at the Good Clinical Practice Institute of XiYuan Hospital.

In this arm, patients take 8g of HuatuoZaizao pill three times a day. Besides，participants will receive basic treatment in accordance with the "Guidelines for diagnosis and treatment of ischemic stroke in China",and the drug and dosage will be formulated by the researchers according to the clinical situation.Treatment lasts for 12 weeks

The National Institutes of Health Stroke Scale (NIHSS) is a 15-item measure of the effect of acute stroke on a variety of areas including level of consciousness, neglect, motor strength, facial palsy, ataxia, dysarthria, and sensory loss.

The CM-SS is a tool, designed according to the Guiding Principles of Clinical Research on New Drugs of Traditional Chinese Medicine issued in 2002, to evaluate the effects of treatments on Traditional Chinese medicine patterns. Scoring is mainly based on some typical TCM symptoms, such as tongue coating and pulse.

Modified Ashworth Scale (MAS) measure spasticity. During the administration of MAS , the examiner passively moves the joint being tested and rates the perceived level of resistance in the muscle groups opposing the movement.It is single-item measures ranging from 0 to 4, where 0 indicates no increase in muscle tone and 4 indicates that the affected part is rigid in flexion or extension.

The Fugl-Meyer Assessment of Sensorimotor Impairment (FM) is one of the first scales developed to quantitatively measure the recovery from hemiplegic stroke. It assesses recovery in five domains, including motor functioning of the upper and lower extremities, balance, sensation, joint range of motion, and joint pain in post-stroke patients. Each task is scored on a scale of 0-2, with 0 indicating the patient cannot perform the task and 2 indicating the patient can fully perform the task.
