Clinical Trial Summary

The purpose of the study is to compare the effect of different doses of energies of high-intensity LASER on pain and functional activity in patients with chronic knee OA.

Description:

Adding HILT to the traditional physical therapy program may reduce pain and improve the functional status of the affected joints. This may provide clinicians with an understanding of the different treatment modalities that may improve the quality of life of patients suffering from chronic knee OA. Which may benefit a wide range of individuals affected by this chronic and widespread disease all over the world.

Although little is known about the efficacy or mechanism of action of what has been termed ''high-intensity laser therapy'' using Nd: YAG lasers it has become commercially available in veterinary practice and is being marketed for the treatment of musculoskeletal disease. clinical research specific to Nd: YAG high-intensity laser therapy is required, as it is being used with little supporting evidence.

As there was no evidence about the best protocol for the treatment of knee OA as each study was using different doses, different sites of application, different number of phases, frequency of sessions, and the interval between sessions that make it difficult to have the best results. Specifically, the dosage range in literature was ranged from 1250 to 3000 J as total energy transmitted during one treatment session. The current study is an attempt to answer the question of which dosage of the energy of high-intensity LASER is more effective on pain and functional activities in patients with chronic knee OA at the third degree of osteoarthritis as determined by (Kellgren/Lawrence grading system) as it was recommended that LASER is an ideal treatment for subjects in the later stages of OA .
