Phase 2 - findings of the feasibility study
Eight physiotherapists invited 23 eligible patients. Of these patients, 13 signed informed consent forms and were enrolled in the study and the rest declined to participate after reading the information letter. Eight physiotherapists and 13 patients completed the follow-up questionnaire. No patients were lost to follow-up and two physiotherapists were lost to follow-up due to self-reported lack of experience with the Stratified Blended Physiotherapy approach and therefore were not willing to participate in the follow-up data collection. Physiotherapist and patient characteristics are presented in Tables
