Shoulder Pain / Rotator Cuff

Published: Last updated:

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

ConditionShoulder Pain
Wavelengths810nm, 830nm, 850nm
Dosage6 J per point, 4-6 points
Irradiance50-100 mW/cm²
Duration30-60 seconds per point
Frequency3x per week for 4-6 weeks
Body Zoneshoulder
Evidence LevelModerate

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)
