- The Third Affiliated hospital of Zhejiang Chinese Medical University
- Brief Summary
Most ischemic stroke patients are in recovery phase, often accompanied by motor impairment, but they lack effective treatment. The appearance of nerve growth factor (NGF) promotes the development of neuroprotective therapy, but it has little effect on stroke because of the blood-brain barrier (BBB). Electroacupuncture (EA) has been used for stroke, while there is no significant clinical effect for recovery phrase. Consequently, we will conduct a multicentre, randomised, controlled, assessor-blinded clinical trial to assess the effectiveness and safety of EA combined with NGF treatment on ischemic stroke recovery.

Group Intervention Description EA + NGF group EA Patients take supine position. After skin disinfection with 75% ethanol routine disinfection, the stainless needle will be inserted in GV20（Baihui) and the stainless needle will be inserted in GV26 (Shuigou), acupoints will be stimulated manually until patients feel soreness, distension or heaviness . Then, the needles are stimulated by using an acupuncture point nerve stimulator , 28 days as a course of treatment, once a day;The 20ug nerve growth factor will be dissolved in 1 ml sterile water for injection and then injected intramuscularly at gluteal muscle, once a day for 4 weeks before the EA intervention. Dose modification is not allowed for mNGF. sham EA + placebo group physiological saline The sham EA intervention a is that the stimulator is connected to the needle handle on GV20 and GV26 without power for 40 min intervention,once a day for 4 weeks;The patients will receive 1ml volume of physiological saline (PS) injected into the gluteal muscle, once a day for 4 weeks before the sham EA intervention. EA + placebo group EA Patients take supine position. After skin disinfection with 75% ethanol routine disinfection, the stainless needle will be inserted in GV20（Baihui) and the stainless needle will be inserted in GV26 (Shuigou), acupoints will be stimulated manually until patients feel soreness, distension or heaviness (the reaction of "De Qi"). Then, the needles are stimulated by using an acupuncture point nerve stimulator (HANS-200, Nanjing Jinsheng, Ltd., China) with a frequency of 2/100 Hz and an intensity of 3 mA for 40 min (a homemade relay cycled power to the electrode for 6 sec on and 6 sec off), 28 days as a course of treatment, once a day;The patients will receive 1ml volume of physiological saline (PS) injected into the gluteal muscle, once a day for 4 weeks before the EA intervention. sham EA + NGF group sham EA The sham EA intervention a is that the stimulator is connected to the needle handle on GV20 and GV26 without power for 40 min intervention,once a day for 4 weeks;The 20ug nerve growth factor will be obtained from Hiteck Biopharmaceutical Co., Ltd, Wuhan, China. mNGF will be dissolved in 1 ml sterile water for injection and then injected intramuscularly at gluteal muscle, once a day for 4 weeks before the sham EA intervention.

- Primary Outcome Measures
Name Time Method the modified Rankin Score the end of treatment (week 4) in all four groups. the modified Rankin Score is a common indicator to evaluate motor function in stroke patients.The modified Rankin Score ranges from 0 to 6, and the more severe the neurological deficit, the higher the score.
- Secondary Outcome Measures
Name Time Method Modified Barthel Index (MBI) Modified Barthel Index (MBI) is recorded at baseline (week 0), Mid-term treatment (week 2) and end of treatment (week 4) in all four groups. Modified Barthel Index (MBI) is a common indicator to evaluate motor function.The maximum total score of Modified Barthel Index is 100, with a higher score meaning less dependent to help.
Fugl-Meyer Assessment of motor function score (FMA) Fugl-Meyer Assessment of motor function score (FMA) is recorded at baseline (week 0), Mid-term treatment (week 2) and end of treatment (week 4) in all four groups. Fugl-Meyer Assessment of motor function score (FMA) is a common indicator to evaluate motor function.simplified Fugl-Meyer Assessment of motor function score sums up a total score (maximum 100 points ), including an assessment of the upper extremity (maximum 66 points) and lower extremity (maximum 34 points).
timed up and go test (TUGT) timed up and go test (TUGT) is recorded at baseline (week 0), Mid-term treatment (week 2) and end of treatment (week 4) in all four groups. timed up and go test (TUGT) is a common indicator to evaluate motor function.In the timed up and go test, each patient is asked to stand up from an armchair at height 45 cm, walk a distance of 3 m, turn, walk back to the chair, and sit back down in chair . With interval of one minute rest, a patient is required to repeat the test three times to take its mean for statistical analysis.
Tinetti Performance Oriented Mobility Assessment (POMA) Tinetti Performance Oriented Mobility Assessment (POMA) is recorded at baseline (week 0), Mid-term treatment (week 2) and end of treatment (week 4) in all four groups. Tinetti Performance Oriented Mobility Assessment (POMA) is a common indicator to evaluate motor function.POMA scale can be used to assess the balance with B-POMA including nine components (sitting balance, arises, attempts to arise, immediate standing balance, standing balance, nudged, eyes closed, turning 360 , and sitting down; maximum 16 points) and to evaluate the gait with G-POMA including seven components (initiation of gait, step length, step symmetry, step continuity, path, trunk, and walking stance; maximum 12 points) . A patient with POMA scored less than 24 points suggets balance dysfunction and scored less than 15 points indicates danger of falling.
