Measures of knee pain and quality of life indicators following strawberry and control interventions in a 26-week crossover trial in obese adults with symptomatic knee osteoarthritis (n = 17/group).
| Variables | Baseline | Strawberry (12-Week) | Washout (2-Week) | Control (12-Week) | p-Value * |
|---|---|---|---|---|---|
| HAQ-DI | 0.6 ± 0.1 | 0.4 ± 0.1 | 0.5 ± 0.1 | 0.6 ± 0.1 | 0.026 |
| VAS PAIN | 1.4 ± 0.2 | 0.8 ± 0.1 | 1.1 ± 0.1 | 1.0 ± 0.2 | 0.17 |
| VAS HEALTH | 0.7 ± 0.1 | 1.0 ± 0.2 | 0.9 ± 0.2 | 0.7 ± 0.1 | 0.13 |
| ICOAP (Constant pain) % | 31.8 ± 3.5 | 13.8 ± 3.6 | 32.1 ± 3.7 | 24.2 ± 4.1 | 0.01 |
| ICOAP (Intermittent pain) % | 38.5 ± 3.4 | 24.3 ± 4.7 | 34.1 ± 2.2 | 34.6 ± 3.0 | 0.02 |
| ICOAP (Total pain) % | 35.4 ± 3.1 | 19.4 ± 3.7 | 33.2 ± 2.2 | 29.9 ± 3.0 | 0.007 |
Values are means ± SEMs obtained from a linear mixed-effects model with time as within-subject factor and intervention group as a between-subject factor; * Strawberry 12-week vs. Control 12-week adjusted for Baseline; p < 0.05 in bold; ICOAP: intermittent and constant osteoarthritis pain; HAQ-DI: health assessment questionnaire disability index; VAS: visual analog scale.
