The Effects of Using Photobiomodulation Led Wrap on Joints with Osteoarthritis

Background: Canine osteoarthritis (OA) is a progressive degenerative disease, which can have a malign effect on quality of life. Clinical signs are often managed using nonsteroidal anti-inflammatory drugs (NSAIDs). However, a multi-modal approach is desired which can include analgesic medication, disease-modifying OA agents, weight management, exercise modification, physical rehabilitation modalities, environment modifications, and surgical procedures. However, more recently, photobiomodulation therapy (PBMT), also known as low-level laser (light) therapy (LLLT) has become a popular modality in OA management.

Materials and Methods: To investigate the potential use of PBMT, an LED wrap was trialled on 13 canine patients (4–13 years) diagnosed with lower limb OA. A set of baseline measurements (repeated weekly for 3 weeks) were collected from each participant before the wrap was applied to the affected joint for a total of 11 weeks. Measurements included limb circumference, joint range of motion using a goniometer, and dynamic movement was recorded with a standard pathway and Helsinki pain score. Further measurements were taken after 4 and 11 weeks of using the wrap.

Results: A paired-sample t-test determined that there was a significant (p < 0.001) difference in stifle measurement between the baseline and week 11 of the treatment plan. No significant difference was detected between the baseline measurement and week 4 of the treatment.

Conclusion: These results suggest improved mobility after LED wrap use; however, variability within the participant group reduced the reliability of the further analysis. In addition, clinicians observed increased fluidity in movement while owners reported improved clinical signs.
