Table 1.
Changes in the parameters of the Lequesne index and aspirated synovial fluid volumes before, during, and after LLLT.
| Before LLLT (time of 1st LLLT) | 2 weeks after 1st LLLT (time of 2nd LLLT) | 2 weeks after 2st LLLT (time of 3rd LLLT) | 1-month follow-up | 3-month follow-up | 6-month follow-up | |
|---|---|---|---|---|---|---|
| Average aspirated SF volume in mL | 16.44 ± 3.96 | 15.51 ± 3.61 | 5.78 ± 2.43∗ | 6.38 ± 3.04∗ | 7.58 ± 3.29∗ | 9.22 ± 3.46 |
| Lequesne functional index | 13.31 ± 4.11 | 12.44 ± 2.79 | 4.47 ± 2.33∗ | 4.05 ± 2.14∗ | 4.74 ± 2.22∗ | 6.15 ± 2.78 |
LLLT: low-level laser therapy; mL: milliliter. ∗Statistical analysis of 3rd LLLT (at this time, patients have completed 2 LLLT treatments), 1-month follow-up, and 3-month follow-up periods as compared with the time before LLLT or received only 1 LLLT and at 6 months follow-up (p < 0.05). Values are expressed as mean ± standard deviation (SD).
