Cognitive Functional Therapy for Chronic Shoulder Pain: Pilot and Feasibility Study

This pilot randomized controlled clinical trial (RCT) will assess the feasibility and identify the key components necessary for conducting the main RCT, which will involve the comparison of Cognitive Functional Therapy with Therapeutic Exercises in individuals with chronic shoulder pain. The main questions it aims to answer are: * What barriers to the participation of the included individuals might arise? * Will the assessment procedures and outcome measures be feasible and suitable? * What time will be necessary to conduct the assessments? * Will participants be willing to be randomized to the proposed treatment groups? * What barriers to the clinical delivery of Cognitive Functional Therapy in the healthcare system might exist? * Will the treatment(s) be acceptable to patients? * Will participants adhere to the treatment? * What will the recruitment rates be per week/month? * Will there be any selection bias? * Will participant retention be high among the allocation groups? * Will the data be complete? * What will the data variability be? * Will the treatment effects/outcomes be consistent with expectations and previous literature?
