Chinese University of Hong KongEffects of Nunchaku Exercise for Improving Frozen Shoulder 50 Exercise-Based
Clinical Trial NCT07486193 is an interventional study for Adhesive Capsulitis and is currently not yet recruiting. Enrollment is planned to begin on March 30, 2026 and continue until the study accrues 50 participants. Led by Chinese University of Hong Kong, this study is expected to complete by December 31, 2026. The latest data from ClinicalTrials.gov was last updated on March 20, 2026.
Brief Summary
The goal of this clinical trial is to investigate if nunchaku exercise works to treat adhesive capsulitis, or frozen shoulder in middle-aged or older adults. It will also learn about the adherence of this exercise intervention. The main questions it aims to answer are:
- Does practicing nunchaku exercises help reduce shoulder pain and improve shoulder movement?
- Do people stick with nunchaku exercises better, and s...
Detailed Description
Adhesive capsulitis, or frozen shoulder, is a progressive fibro-inflammatory condition characterized by synovitis, capsular thickening, and collagen remodeling, leading to substantial restrictions in active and passive shoulder motion. These movement limitations commonly result in impaired sleep, difficulties in self-care, and reduced capacity for work and leisure activities. Although conservative rehabilitation is t...Show More

Active ComparatorShoulder Mobilization and Stretching Exercise (SMSE) | Shoulder Mobilization and Stretching Exercise (SMSE) Participants in this group will be offered a 12-week rehabilitation program consisting of two 60-minute sessions per week. This program has been designed by a registered physiotherapist in accordance with the Hospital Authority of Hong Kong's self-care guidelines. Each session includes joint mobilization exercises, end-range stretching using a towel or stick, and muscle-strengthening and stabilizing exercises. The tr...Show More |
ExperimentalNunchaku Exercise | Nunchaku exercise Participants randomized to the Nunchaku Exercise group will participate in a 12-week training program consisting of two 60-minute sessions per week. To prioritize safety and minimize the risk of injury, you will use a soft towel with a knot at each end to simulate nunchaku movements (Figure 1). The training focuses on the level one syllabus of the standard nunchaku system, which involves rhythmic multi-angle movement...Show More |
Primary Outcome Measures
Secondary Outcome Measures
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
Shoulder Pain and Disability Index (SPADI) | SPADI will be used to assess shoulder pain and functional limitations during daily living activities. SPADI, comprising 5 items to assess pain and 8 to assess disability, is widely used to evaluate the negative impact of frozen shoulder. Its Chinese version has been validated in China with good internal consistency and reliability | From enrollment to the end of follow-up period at 24 weeks |
| Outcome Measure | Measure Description | Time Frame |
|---|---|---|
Visual Analog Scale for Pain (VAS) | The perception of pain during resting, and ordinary daily activities will be assessed using VAS. Participants will be instructed to draw a mark on a 10-cm line, with one end indicating no pain and the other indicating worst pain imaginable, to indicate their pain level | From enrollment to the end of follow-up period at 24 weeks |
Constant-Murley Score (CMS) | Overall shoulder function will be assessed using the CMS. CMS assesses 4 domains, including pain, how shoulder function affects daily activity, pain-free range of motion, and muscle strength. This instrument has been validated in China. This assessment will be conducted by a registered physiotherapist. | From enrollment to the end of follow-up period at 24 weeks |
Pain-free Range of Motion (ROM) | The pain-free ROM of forward and lateral elevation during flexion and abduction will be measured using a goniometer. The assessment will be conducted by a registered physiotherapist. | From enrollment to the end of follow-up period at 24 weeks |
Enjoyment of intervention | Enjoyment of intervention will be assessed using the Eight-Item Physical Activity Enjoyment Scale (PACES-8). | From mid-intervention at 6 weeks to to the end of follow-up period at 24 weeks |
