Sports adaptation: patients who reported no change in sports activities, a reduce of sports activities or stopped performing sports activities. VISA-A: A score range from 0 to 100 points (with asymptomatic persons expected to score 100 points) used for assessment of physical disability due to AT.25 AAS: A score range from 0 to 10 points (with 0 being unable to walk and 10 being physically active performing high intensity sports on a top level) which includes different sports, working activities and general activities used to assess the level of activity in persons.26 Primary outcome - Quality of Life The majority of AT patients reported moderate or major problems (any problem) on the domains mobility (66%), usual activities (50%) and pain/discomfort (89%).

Median (IQR) self-rated current overall health-status using the EQ-VAS score was 70 points (59-80). Table 2. EQ-5D scores in patients with Achilles tendinopathy.
