研究目的
To evaluate the synergic effect of low-intensity pulsed ultrasound (LIPUS) associated with low-level laser therapy (LLLT) on osteoarthritis of hands and knees.
研究成果
The combined therapy of LIPUS and LLLT was efficient in treating hands and knees osteoarthritis, providing a non-pharmacological and non-invasive treatment option that improves patients' quality of life. The study encourages further investigation into using this combined technology for other chronic joint diseases.
研究不足
The study did not include patients with pre-existing chronic and/or degenerative diseases or those who had undergone drug infiltration treatment three months prior to the study. The improvement in the left hand's functionality did not show statistical significance.
1：Experimental Design and Method Selection:
The study used a device prototype that simultaneously emitted therapeutic ultrasound and photobiomodulation for the treatment of osteoarthritis.
2：Sample Selection and Data Sources:
69 patients, 48 with knee osteoarthritis and 21 with hand osteoarthritis, were selected. Exclusion criteria included pre-existence of other chronic and/or degenerative diseases.
3：List of Experimental Equipment and Materials:
A device prototype designed and assembled by the Technological Support Laboratory of the Institute of Physics of S?o Carlos, University of S?o Paulo.
4：Experimental Procedures and Operational Workflow:
Intervention protocol was applied twice a week, totaling 8 sessions. Parameters for ultrasound and laser were set up for hands and knees osteoarthritis treatment.
5：Data Analysis Methods:
Patients were evaluated by WOMAC for knee osteoarthritis and AUSCAN for hands osteoarthritis, and all filled out the VAS pain questionnaire. Statistical analysis was performed using the "t" Student test.
