About this study
Official title: Effectiveness of Electroacupuncture Combined With Cupping Therapy in Patients With Shoulder Tendinitis and qi Stagnation and Blood Stasis Syndrome
This study aims to evaluate the effectiveness of electroacupuncture combined with vacuum cupping therapy in treating simple periarthritis of the shoulder associated with the traditional medicine syndrome of Qi stagnation and blood stasis. Shoulder periarthritis is a common condition that causes pain, stiffness, and limited movement of the shoulder due to injury or inflammation of the muscles, tendons, ligaments, and surrounding soft tissues. It can interfere with daily activities such as dressing, lifting objects, sleeping, and working.
Electroacupuncture is commonly used to relieve shoulder pain and improve shoulder function. Vacuum cupping therapy is another non-drug treatment that may help improve blood circulation, reduce muscle tightness, decrease pain, and improve mobility. However, there is currently limited evidence about whether combining electroacupuncture with vacuum cupping provides better results than electroacupuncture alone in patients with shoulder periarthritis and Qi stagnation-blood stasis syndrome. This study is being conducted to determine whether the combined treatment is more effective and safe.

A total of 54 participants with simple shoulder periarthritis and Qi stagnation-blood stasis syndrome will be enrolled in the study. Participants will be randomly assigned to one of two groups:
Group 1: treatment with electroacupuncture alone. Group 2: treatment with electroacupuncture combined with vacuum cupping therapy.
All participants will also receive advice on shoulder exercises, posture, and daily activities to support recovery. Treatments will be performed by licensed traditional medicine practitioners.
Each participant will take part in the study for two weeks. Assessments will be performed before treatment, after one week, and after two weeks. The study will evaluate:
Pain intensity using the Visual Analogue Scale (VAS). Shoulder pain and disability using the Shoulder Pain and Disability Index (SPADI).
Shoulder range of motion using the McGill-McRomi Range of Motion Index. Any side effects or unwanted events related to treatment. Possible benefits of participating in this study include reduced shoulder pain, improved movement and daily function, and close monitoring by health care professionals. Participants may also benefit from receiving non-drug therapies at no cost during the study period. The findings of this research may help improve future treatment options for patients with shoulder pain.
Possible risks of electroacupuncture include mild pain at the needle site, minor bleeding, bruising, dizziness, or fainting. Possible risks of vacuum cupping include temporary discomfort, skin redness, bruising, or mild pain in the treated area. These side effects are usually mild and temporary. If any unexpected problem occurs, participants will receive prompt medical attention.
Participation in this study is completely voluntary. Participants may refuse to join or may withdraw from the study at any time without affecting their usual medical care. All personal information collected during the study will remain confidential and will only be used for research purposes.

ElectroacupunctureProcedure or surgery
Also called Vacuum Cupping Therapy
Intervention Description: Electroacupuncture Electroacupuncture is administered using the KWD-808I device and sterile, single-use needles (0.30 x 25 mm). The protocol targets a standardized set of acupoints: LI15 (Jianyu), LI14 (Binao), LI16 (Jugu), SI9 (Jianzhen), SI11 (Tianzong), LU1 (Zhongfu), LU2 (Yunmen), GB21 (Jianjing), and BL17 (Geshu).
Distinguishing Technical Details:
Sensation: Needles are inserted to achieve the "De Qi" sensation (aching, heaviness, or distension).
Electrode Pairing: Electrodes are connected in specific pairs: LU1-LU2, LI15-LI16, and SI11-SI9.
Waveform \& Frequency: A continuous wave at a 10Hz frequency is used. Intensity is titrated to the patient's maximum comfortable tolerance (distension without sharp pain).
Regimen: 20 minutes per session, daily for 10 sessions over 2 weeks (excluding weekends).
All procedures are performed by licensed Traditional Medicine physician physicians with over 5 years of experience
Vacuum Cupping TherapyProcedure or surgery
Vacuum Cupping Therapy (VCT) VCT uses 4.5 cm diameter cups and a manual pump to create negative pressure. Standardized procedure: Medium suction force (3 manual pumps) is applied for 5 minutes per session.
Treatment sequence: VCT is performed first, followed by a 10-minute rest period before electroacupuncture.
Acupoint selection: Targets Jianyu (LI15), Quyuan (SI13), Tianzong (SI11), and Naoshu (SI10) on the affected shoulder, plus bilateral Geshu (BL17).
Regimen: 3 sessions over a 2-week period with 3-day intervals. Safety: Vaseline is applied to cup rims to ensure a seal and prevent skin irritation.
All procedures are conducted by licensed Traditional Medicine physicians with at least 5 years of experience

What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Analogue Scale
The Visual Analogue Scale (VAS) is a validated tool used to quantify pain intensity. It consists of a 10cm horizontal line where the 0 cm mark represents "no pain" and the 10 cm mark represents the "worst pain imaginable".
How the measure is taken: Participants are instructed to mark a single point on the line that best reflects their current level of shoulder pain. The researcher then measures the distance from the 0 cm starting point to the patient's mark in centimeters to obtain a numerical score.
Pain Level Definitions:
No pain (0 cm). Mild (1-3 cm): Slight pain that does not significantly interfere with concentration.
Moderate (4-6 cm): Noticeable pain that may interfere with daily activities, though the patient can still work.
Severe (7-10 cm): Distressing pain that significantly limits daily activities and affects sleep.
Measured: Measured at 3 time points: Day 1 (baseline, prior to intervention), Day 5 (post-intervention), and Day 10 (post-intervention).
Secondary outcomes (3)
Shoulder Pain and Disability Index - SPADI.
The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire containing 13 items used to assess shoulder pathology. It is divided into two subscales: Pain (5 items) and Disability (8 items).
How it is measured: Participants rate their pain and difficulty with daily activities (e.g., washing hair, putting on a shirt) on a scale of 0 to 10, where 0 represents "no pain/no difficulty" and 10 represents "worst pain/requires help".
Scoring Criteria: Subscale scores are averaged and converted into a total percentage score (0-100%). A higher percentage indicates greater pain and more significant functional impairment
Measured: Measured at 3 time points: Day 1 (baseline, prior to intervention), Day 5 (post-intervention), and Day 10 (post-intervention).
McGill Range of Motion Index - McGill-McRomi.
The McGill Range of Motion Index: provides an objective assessment of the shoulder's functional movement capacity without requiring specialized equipment. Record the maximum range of motion achieved in three movements: shoulder abduction, internal rotation, and external rotation.
Criteria: Results are categorized into 4 grades:
Grade 0: No limitation (e.g., Abduction >150°). Grade 1: Mild limitation (e.g., Abduction 101-150°). Grade 2: Moderate limitation (e.g., Abduction 51-100°). Grade 3: Severe limitation (e.g., Abduction 0-50°).
Measured: Measured at 3 time points: Day 1 (baseline, prior to intervention), Day 5 (post-intervention), and Day 10 (post-intervention).
Adverse Events
Adverse events are monitored throughout the 2-week intervention and recorded as qualitative data (Yes/No) based on clinical observation and patient reports
. Criteria for Electroacupuncture: Fainting: Occurs if a patient feels dizzy, pale, or breaks into a cold sweat during needling.
Local Trauma: Includes minor bleeding or bruising at the needle site, or the rare risk of a broken needle.
Infection: Monitoring for redness or swelling at acupoints.
Criteria for Vacuum Cupping:
Bruising: Skin discoloration from suction; while common, it is monitored if severe or persistent.
Unbearable Pain/Tension: Acute discomfort at the cup site necessitating immediate removal.
Skin Reactions: Includes local irritation, allergies, or burns. General Symptoms: Patients are screened for headache, nausea, and dizziness. All procedures are performed by licensed TCM physicians to ensure safety
Measured: Adverse events are monitored throughout the 2-week intervention
