Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Our primary outcome measurement is the VISA-A score. This measures pain, function and activity level. It is validated en reliable for the chronic Achilles tendinopathy. | — |
Secondary
| Measure | Time frame |
|---|---|
| Our secundary outcome measurements are as follows: - The painDETECT questionnaire. - The Pain Coping Inventory (PCI) questionnaire - Subjective function of the Achilles tendon (5-point Likert scale) and subjective recovery (7-point Patient's Global Assessment scale) - Physical examination: waist circumference, length, weight, foot posture index, palpation pain (VAS 0-100), flexibility and strength gastrocnemius and soleus muscle, jumping height (cm) and pain during jump test (VAS 0-100) and 10 times hopping (VAS 0-100, part of the VISA-A questionnaire) (First 66 patients) - Degree of neovascularisation (determined with standarised Power Doppler Ultrasonography examination) before and after eccentric/isotonic calf exercises or rest (First 66 patients) - Subjective patient satisfaction (excellent / good / fair / poor) - Return to sports (Return to desired sport on pre-injury level / return to desired sport but on a lower level / return to sports but not desired sport / no return to sports) - Time to return to full training in desired sport. - Compliance to the exercise programme and return to sports activity programme (RPE score x duration of activity) | — |
