简要总结
The purpose of this study is to determine the effects of Pain Neuroscience Education (PNE) and Graded Motor Imagery (GMI) combined with conventional physiotherapy on pain, kinesiophobia, central sensitization, functional disability, range of motion, and quality of life in patients with Type II diabetic adhesive capsulitis. Adhesive capsulitis is a common musculoskeletal condition characterized by pain and progressive restriction of shoulder movement, particularly among individuals with diabetes mellitus. Conventional physiotherapy is widely used to restore shoulder mobility and function; however, it may not adequately address central sensitization and fear of movement. Pain Neuroscience Education aims to improve patients' understanding of pain mechanisms and reduce maladaptive beliefs, while Graded Motor Imagery targets cortical reorganization and movement-related fear. The combination of these interventions with conventional physiotherapy may improve clinical outcomes and enhance quality of life.
详细描述
This study is a randomized controlled trial with a parallel-group design to evaluate the effectiveness of Pain Neuroscience Education (PNE) and Graded Motor Imagery (GMI) combined with conventional physiotherapy in patients with Type II diabetic adhesive capsulitis. A total of 50 participants meeting the inclusion and exclusion criteria will be recruited using a non-probability convenience sampling technique and randomly allocated into two groups.
- Experimental Group: Participants will receive Pain Neuroscience Education, Graded Motor Imagery, and conventional physiotherapy.
- Control Group: Participants will receive conventional physiotherapy alone. Both groups will undergo treatment for 6 weeks, with three treatment sessions per week. The experimental intervention will include weekly Pain Neuroscience Education sessions, progressive Graded Motor Imagery (laterality recognition, motor imagery, and mirror therapy), along with conventional physiotherapy consisting of joint mobilization, stretching, strengthening, range-of-motion exercises, and functional training.
Outcome assessments will be performed at baseline (Week 0), mid-treatment (Week 3), and post-treatment (Week 6). The primary outcome measures will include pain intensity (Numeric Pain Rating Scale), shoulder range of motion (Universal Goniometer), functional disability (Shoulder Pain and Disability Index), kinesiophobia (Tampa Scale of Kinesiophobia), and central sensitization (Central Sensitization Inventory). Quality of life will be assessed using the Short Form-36 (SF-36) questionnaire. The findings of this study will determine whether adding Pain Neuroscience Education and Graded Motor Imagery to conventional physiotherapy provides superior improvements in pain, psychological outcomes, functional ability, and quality of life compared with conventional physiotherapy alone.

研究组 & 干预措施
Experimental Group (PNE + GMI + Conventional Physiotherapy)
Participants assigned to the experimental group will receive Pain Neuroscience Education (PNE) and Graded Motor Imagery (GMI) combined with conventional physiotherapy. The intervention will be delivered over 6 weeks, with three supervised treatment sessions per week. Pain Neuroscience Education will address pain neurophysiology, central sensitization, fear-avoidance beliefs, coping strategies, and self-management. Graded Motor Imagery will include laterality recognition, motor imagery, and mirror therapy, progressing according to the treatment protocol. Conventional physiotherapy will consist of shoulder range-of-motion exercises, joint mobilization, stretching, strengthening, proprioceptive training, functional exercises, and activity-specific rehabilitation.

Participants assigned to the control group will receive conventional physiotherapy alone for 6 weeks, with three supervised treatment sessions per week. Treatment will include pain relief modalities, shoulder range-of-motion exercises, stretching, joint mobilization, strengthening exercises, proprioceptive exercises, functional training, and activity-specific rehabilitation without Pain Neuroscience Education or Graded Motor Imagery.

结局指标
主要结局
Pain intensity measured by Numeric Pain Rating Scale (NPRS)
时间窗: Baseline (Week 0), Week 3, and Week 6
Pain intensity will be assessed using the Numeric Pain Rating Scale (NPRS). The Numeric Pain Rating Scale (NPRS) is a self-reported outcome measure used to assess pain intensity in musculoskeletal and rehabilitation settings. The scale ranges from 0 to 10, where 0 indicates "no pain" and 10 indicates "worst imaginable pain".
Shoulder Pain and Disability Measured by the Shoulder Pain and Disability Index (SPADI).
时间窗: Baseline (Week 0), Week 3, and Week 6
Functional disability will be evaluated using the Shoulder Pain and Disability Index (SPADI). The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire developed to assess pain and functional disability associated with shoulder disorders, particularly adhesive capsulitis and other musculoskeletal shoulder conditions. The SPADI consists of 13 items divided into two subscales: a pain subscale containing 5 items and a disability subscale containing 8 items. Each item is scored using a numerical rating scale ranging from 0 to 10, where 0 represents "no pain" or "no difficulty" and 10 represents "worst pain imaginable". Higher scores indicate greater pain and disability.
Shoulder Range of Motion Measured Using a Universal Goniometer
时间窗: Baseline (Week 0), Week 3, and Week 6
Active shoulder range of motion (flexion, abduction, internal rotation, and external rotation) will be measured using a universal goniometer.
Kinesiophobia Measured by the Tampa Scale of Kinesiophobia (TSK-17).
时间窗: Baseline (Week 0), Week 3, and Week 6
Kinesiophobia will be assessed using the Tampa Scale of Kinesiophobia (TSK-17).The Tampa Scale of Kinesiophobia (TSK) is a self-reported questionnaire used to assess fear of movement, fear of reinjury, and avoidance behaviors associated with pain and musculoskeletal disorders.The most commonly used version is the TSK-17, which consists of 17 items assessing beliefs related to physical activity and movement-related fear. Each item is scored on a 4-point Likert scale ranging from 1 ("strongly disagree") to 4 ("strongly agree"). The total score ranges from 17 to 68, with higher scores indicating greater levels of kinesiophobia and fear-avoidance behavior.
Central Sensitization Measured by the Central Sensitization Inventory (CSI).
时间窗: Baseline (Week 0), Week 3, and Week 6
Central sensitization will be assessed using the Central Sensitization Inventory (CSI). The Central Sensitization Inventory (CSI) is a self-reported questionnaire developed to identify symptoms associated with central sensitization in individuals with chronic pain disorders. The CSI consists of 25 items that assess health-related symptoms commonly associated with central sensitization syndromes. Each item is scored on a 5-point Likert scale ranging from 0 ("never") to 4 ("always"). Higher scores indicate greater symptoms related to central sensitization.
