Plain English Summary
Background and study aims
Spasticity is a condition in which certain muscles are continuously contracted, causing stiffness or tightness. It is one of the most common complications of stroke, usually occurring in the convalescent (recovery) stage 1-6 months after stroke. Spasticity harms the recovery of motor function and causes malformation, thus damaging the daily living abilities of patients and increasing the caring burden for family and society. The aim of this study is to assess the effect of acupuncturing “Wang’s Jiaji” acupoints on spasticity after stroke.
Who can participate?
Patients between 40 and 75 years old in the convalescent stage of ischemic stroke
What does the study involve?
Participants are randomly allocated to one of two groups. All of the participants are given basic treatment according to the guidelines. The treatment group receive acupuncture treatment once a day 5 times per week for two weeks. The control group take the drug baclofen 3 times a day for two weeks. Upper and lower limb motor function of the affected side is assessed at the start of the study and 2, 4 and 12 weeks later.
What are the possible benefits and risks of participating?
It is expected that participants will experience lower frequency and severity of limb spasticity as well as improved motor function and strength, thus improving quality of life and avoiding the side effects of drugs and operations. Furthermore, the evidence gained from this study will be helpful in future research projects. The risks of taking part are minimal. Acupuncture is a very safe treatment when given by properly trained clinicians. Occasionally acupuncture can make people feel nauseous or faint or experience a temporary increase in pain either during or after treatment. Participants are warned of these potential side effects before consenting to have acupuncture.
Where is the study run from?
Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University (China)
When is the study starting and how long is it expected to run for?
January 2017 to December 2018
Who is funding the study?
Beijing Municipal Health and Family Planning Commission (China)

A clinical study to assess the influence of acupuncturing “Wang’s Jiaji” acupoints on limb spasticity of patients in convalescent stage of ischemic stroke
Compared with taking baclofen, acupuncturing “Wang’s Jiaji” acupoints can improve limb spasticity of patients in convalescent stage of ischemic stroke equally or better.

A total of 100 participants will be randomly assigned to two different groups. All of the patients will be given basic treatment according to the guideline for prevention and treatment of cerebrovascular diseases.
Treatment group: “Wang’s Jiaji” acupoints including 16 acupoints 3 cun away from beneath the second, fourth, sixth, eighth, tenth, twelfth spinous process of thoracic vertebra and the second, fourth spinous process of lumbar vertebra. Operation: patients in lateral position, affected extremities up. Needles are inserted 25 mm in depth on these 16 acupoints until feeling tactile sensation then manually manipulated by rotation methods to produce a characteristic sensation known as "De Qi". Technique: mild reinforcing and attenuating,retaining the needle for 30 minutes. When all the needles inserted, needle handles need to be a line horizontally and vertically. The treatment will be given once a day and 5 times a week in weekdays, the course lasts two weeks.
Control group: Participants will take baclofen 5mg per time and 3 times a day, the dose may increase to 10mg per time according to level of spasticity. The course lasts two weeks.
Primary outcome measure
Upper and lower limb motor function of affected side, assessed using Simplified Fugl-Meyer (FMA) at baseline, 2 weeks, 4 weeks and 12 weeks after first acupuncture
Secondary outcome measures
1. Muscular tension assessed using Modified Ashworth scale at baseline, 2 weeks, 4 weeks and 12 weeks after first acupuncture
2. The ability of daily living assessed using Modified Barthel scale at baseline,2 weeks,4 weeks and 12 weeks after first acupuncture
3. The level of spasticity assessed using electromyography at baseline and 12 weeks after first acupuncture
