Findings of studies that assessed outcomes immediately after exercise (45 min postintervention)
| Treatment modes | Tendon affected | First author (year) | Pain | Functional disability | ROM | Strength | QoL | Structural integrity | Cortical inhibition |
| Isometric exercise versus isotonic exercise | Rio (2015)20 | ↓ (ΝRS) | – | – | ↑ | – | – | ↑ | |
| Patellar | Rio (2017)35 | ↓ (ΝRS) | – | – | – | – | – | – | |
| Holden (2020)22 | ↔ (NRS) | – | – | – | – | ↔ | – | ||
| Overall isometric versus isotonic exercise (evidence level) | ↔ (3) | – | – | ↑ (3) | – | ↔ (3) | ↑ (3) | ||
↓: lower at statistical significance*; ↑: higher at statistical significance*; ↔: no statistically significant difference.
*With the first versus the second intervention.
NRS, Numeric Rating Scale; QoL, quality of life; ROM, range of movement.
