Frozen shoulder :
• disorder of progressive pain and decrease of range of motion of shoulder articulation
• the main causation of shoulder pain and dysfunction in the middle and older age population
• treatment option:
• ice cooling, medicaments, exercise, TENS, ultrasound diathermy
• Low power laser therapy with exercise will decrease shoulder pain and increase the range of motion of the shoulder articulation
• improve the quality of life of patients with frozen shoulders
• Design comparison of parameter before and after therapy of frozen shoulder patients
• OPD Rehab.Med.,Rheumatology Div,Dept.Internal Med,
• December 2004 to April 2005
• Frozen shoulder patients not less than 18 years of age
• VAS not less than 8
• Cooperative
• Informed consent
• Cases with trauma of shoulder articulation
• Rheumatoid arthritis and spondyloarthritis with shoulder involvement
• Following or under corticosteroid injection therapy within the last 3 months
• Patients with abduction range of motion less than 90 degree
• patients with contraindication of laser therapy
• patients who are unable to perform shoulder exercise properly
Laser device
• Wavelength : 830 nm
• Output : 30 mW
• Dose : 30 J per treatment
• Continuous wave
• 3 times per week for 3 weeks

RESULTS AND DISCUSSION
• Significant decrement of shoulder pain before and after treatments following 3 weeks of therapy
• Significant increment of range of motion of shoulder articulations before and after treatments of low power laser therapy with shoulder exercises following 3 weeks of therapy
CONCLUSIONS
• LOW POWER LASER THERAPY AND EXERCISES OF SHOULDER ARTICULATION IS EFFECTIVE AND EFFICIENT MODALITIES TO TREAT FROZEN SHOULDER
