Shoulder Pain / Rotator Cuff
Source: WALT Guidelines / Clinical Research
Protocol for shoulder pain including rotator cuff tendinopathy, frozen shoulder (adhesive capsulitis), and subacromial bursitis. NIR light is applied to the supraspinatus, infraspinatus, bicipital groove, and acromioclavicular joint areas.
Protocol Parameters
| Condition | Shoulder Pain |
| Wavelengths | 810nm, 830nm, 850nm |
| Dosage | 6 J per point, 4-6 points |
| Irradiance | 50-100 mW/cm² |
| Duration | 30-60 seconds per point |
| Frequency | 3x per week for 4-6 weeks |
| Body Zone | shoulder |
| Evidence Level | Moderate |
Mechanism of Action
PBM reduces inflammation in the subacromial space, promotes tendon healing in rotator cuff fibers, and decreases capsular adhesions through enhanced fibroblast activity. Pain modulation occurs through reduced nerve sensitization and inflammatory cytokine levels.
Key Studies
- Abrisham et al. (2011) - PBM effective for frozen shoulder
- Bal et al. (2009) - PBM for subacromial impingement syndrome
- Santamato et al. (2009) - PBM for rotator cuff tendinitis
Treatment Tips
- *Target the supraspinatus insertion on the greater tuberosity
- *Include the bicipital groove anteriorly
- *For frozen shoulder, treat the anterior and posterior capsule
- *Combine with progressive range-of-motion exercises
Contraindications
- !Complete rotator cuff tear requiring surgery
- !Active shoulder infection
- !Shoulder arthroplasty (consult surgeon)
