STICK2IT - Understanding Why People Do or Do Not Stick With Exercise Treatment for Achilles Tendinopathy

Achilles tendinopathy is a common condition that causes pain and stiffness in the tendon at the back of the ankle. It can make walking, exercise, work, and everyday activities difficult. The main recommended treatment is a programme of progressive tendon-loading exercises, usually supported by an NHS physiotherapist. These exercises can help improve pain and function, but many people find them hard to continue over time. This means that, even though the treatment can work well, some people do not get the full benefit because they are unable to keep up with the exercise programme as advised. People with Achilles tendinopathy often describe worries about making the tendon worse, uncertainty about whether pain during exercise is safe, low confidence, slow progress, and difficulty fitting exercises into daily life. These challenges may be even greater for people from underserved groups, including those living with long-term health conditions, financial pressures, language barriers, or other forms of disadvantage. At present, there is limited research exploring these experiences in a structured way, especially in routine NHS care. The aim of this study is to understand what helps or makes it harder for people to stick with NHS-prescribed progressive tendon-loading exercises for Achilles tendinopathy. The study will focus particularly on the experiences of people who may be at higher risk of poor outcomes or reduced access to support. Up to 30 adults with experience of Achilles tendinopathy and previous NHS physiotherapy treatment will take part in a one-to-one interview. Interviews will last up to 45 minutes and can take place in person, online, or by telephone, depending on what suits the participant best. Participants will be asked about their experiences of living with Achilles tendon pain, being given exercise treatment, and trying to follow that treatment in everyday life. The information from these interviews will be analysed to identify the main barriers and s
