To Evaluate the Therapeutic Effect of Laser Acupuncture in Patients With Acute or Subacute Post Stroke Shoulder Pain

March 4, 2026 updated by: Chang Gung Memorial Hospital
Investigators propose a research design protocol to evaluate the efficacy of laser acupuncture in improving shoulder pain and improving shoulder function recovery after stroke.

Study Overview

Detailed Description

Shoulder pain after stroke, also known as hemiplegic shoulder pain, is one of the common complications after stroke. The overall incidence rate increases with the time after stroke.The existing treatment methods for shoulder pain after stroke are divided into non-drug and drug. Investigators propose a research design protocol to evaluate the efficacy of laser acupuncture in improving shoulder pain and improving shoulder function recovery after stroke.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention group (verum laser acupuncture group )
After blind random allocation, investigators applied verum laser acupuncture on patient with shoulder pain after stroke.
Applied verum laser acupuncture on specific acupoints in patient with post stroke shoulder pain.
Sham Comparator: Control group (sham laser acupuncture group)
After blind random allocation, investigators applied sham laser acupuncture on patient with shoulder pain after stroke.
Applied sham laser acupuncture on specific acupoints in patient with post stroke shoulder pain.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Passive range of motion of shoulder
Time Frame: 3 weeks
Measuring the passive range of motion (Scale unit: angular degree) of shoulder (Abduction ranged from 0-180 degree, flexion ranged from 0-180 degree, external rotation ranged from 0-90 degree) of patient with shoulder pain. The higher degree of range of motion mean the better outcome.
3 weeks
Numerical rating scale
Time Frame: 3 weeks
Measuring the pain level by Numerical rating scale (scale unit: point). The scales ranged form 1 to 10 and the higher scores mean the worse outcome.
3 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Brief Pain Inventory - Short Form (BPI-sf)
Time Frame: 3 weeks
Measuring the level of daily life effect by shoulder pain by Visual graphic rating scale (scale unit: point) of BPI-sf. The scales ranged form 1 to 10 and the higher scores mean the worse outcome.
3 weeks
Visual graphic rating scale (VGRS) of ShoulderQ
Time Frame: 3 weeks
Measuring the pain level on deferent time points by Visual graphic rating scale (scale unit: point) of ShoulderQ. The scales ranged form 1 to 10 and the higher scores mean the worse outcome.
3 weeks
Meridian energy by Meridian Energy Analysis Devices
Time Frame: 3 weeks
Meridian Energy Analysis Devices (MEADs) is a non-invasive meridian energy measurement tool used to Measure the meridian energy of patient. By measuring the current value (scale unit: micro ampere, uA) in the subject's limbs, investigators estimate the energy meridian energy. The higher the current energy value, the higher the meridian energy.
