Comparison of VAS and WOMAC functional status (mean ± SD) scores between Groups A and B using unpaired t-test.
| Outcomes | Scores at 4 weeks postintervention | Unpaired t-test | |||
|---|---|---|---|---|---|
| Group A (n = 20) | Group B (n = 20) | ∆MD (A vs. B) | t value | p value | |
| VAS | 2.92 ± 0.97 | 5.65 ± 2.26 | −2.73 ± −1.29 | −9.17 | <0.05∗ |
| WOMAC-FS | 13.9 ± 3.07 | 19.85 ± 4.70 | −5.95 ± −1.63 | −5.86 | <0.05∗ |
∗ Significant value if p < 0.05; ∆MD: mean difference; SD: standard deviation; WOMAC-FS: The Western Ontario and McMaster Universities Osteoarthritic Index—functional status.
