Abstract
Osteoarthritis is a rheumatic disease characterized by degeneration and decay of cartilage
in the joints. As the disease worsens, the joint space narrows causing numbness and pain,
which often impairs movement. In addition to pharmacological therapy, low-intensity laser
(LILT), high-intensity laser (HILT) and exercise are used to treat osteoarthritis (OA) of the
knee. HILT is a new modality in our country and the experience from its application is small,
especially in the treatment of OA of the knee. Aim of the paper was to compare the effect
of HILT with LILT in the treatment of OA of the knee. Material and methods: This was a
randomized comparative unilateral blind study involving 72 patients divided into two groups.
The first group was treated with HILT, the second group treated with LILT. Outcome measure
was the visual analogue scale (VAS) for pain, which was made on the first and tenth day of
treatment. Statistical significance was defined as p <0.05. Results: We found a significant
difference between the two groups in terms of VAS score after 10 therapies in favor to a
significantly lower score, that is, less pain in the HILT group (p = 0.0035). The comparison
of the VAS score between the two times in the two groups separately showed that in both,
the HILT and the LILT groups, the VAS score after 10 days of therapy was significantly lower
compared to thatat 0 time, for consequently p = 0.00001vsp = 0.00001. Conclusion: Treatment
with HILT and LILT significantly reduces pain and stiffness in patients with OA. Patients
treated with HILT had better results, i.e., had a significant reduction in pain than patients
treated with LILT. HILT was more effective than LILT.
