Conditions

Achillestendinitis overuse of the Achillestendon

Interventions

Eccentric exercise program: Load progression is based on time, pain is not a restriction for exercise therapy. Phase 1: Strengthening. Heel drop with extended en bent knee. Starting with 2d 3x10 r

Heel drop with extended en bent knee. Starting with 2d 3x15hh (single leg) and building up to extra weights (until 15kg) Phase 3: Return to sport

If no complaints remained = return to sport. Decreased complaints: gradually returning to sport, starting with increasing exposure time and intensity during training and thereafter during a match.

Isometric heel raise, building up from 3d 3x30s (doule leg) to 3d 3x45s (single leg) Phase 2

Strength

Concentric heel raise/Excentrisch heel drop with extended and bent knee. Building up from 2d 4x6rep's (double leg) to 2d 4x6 rep's + extra weight up to 20% of body weight (sinlge leg). Moreover, a p

Design outcomes

Primary

Measure	Time frame
Difference in function (VISA-A) between the 2 exercise programs at 16 weeks compared to baseline	—

Secondary

Measure	Time frame
1) Function (VISA-A) at week 4, 8 and 12 compared to baseline 2) Pain (NPRS average, best, worst, functional test) after 16 weeks compared to baseline 3) Pain (NPRS) during the isometric exercises vs eccentric exercises 3) Pain (NPRS) alteration just before and after the exercise therapy during the first 4 weeks 4) Patiënt satisfaction (GPE) at 16 weeks 5) Compliance (%) during the exercise program (16 weeks) 6) Function (VISA-A) at the long term; at week 24, 36 and 52 compared to baseline 7) Pain (NPRS) at the long term; at week 24, 36 and 52 compared to baseline	—
