Home rehabilitation in post-stroke patients seems to be more beneficial than hospital or outpatient treatment, as it allows the repeated practice of tasks incorporated in the person's own environment. However, patient adherence to treatment is a crucial determinant of rehabilitation.

This study aims to develop a clinical trial protocol for the feasibility of a group task-oriented therapy (TOT) program in post-stroke patients, which uses behavioral strategies based on the Theory of Self-Determination to increase adherence to guidance from patients. home exercises.

Initially, a protocol development study will be carried out, without a control group, with pre and post intervention evaluations that will last for 6 weeks. Participants will be 20 individuals diagnosed with stroke who will be submitted to a group TOT program twice a week, lasting 1 hour and to a self-administered home exercise program. Behavioral strategies will be applied during the TOT and the results will be compared with the pre-intervention assessments. The exercises will be organized in the form of four tasks, targeting specific movement components that must be performed for a certain number of repetitions defined individually. The primary outcome measure is adherence to the exercise program and will be assessed using the Exercise Adherence Assessment Scale (EARS-Br); adherence to formal guidance on the home exercise program (self-monitoring diary) and motivational regulations, self-determination and basic psychological needs assessed using the Exercise Behavioral Regulation Questionnaire (BREQ-3) and the Basic Psychological Needs on Exercise scale (BPNES). The feasibility of the methods and protocol performance aiming at a future large-scale randomized controlled clinical trial (RCT) will be explored using predefined feasibility criteria. Feasibility criteria include (1) a minimum 75% adherence rate to home exercise (self-monitoring diary), (2) a minimum 10% change in the Exercise Adherence Rating Scale (EARS-Br) from control week, without behavioral strategies; (3) at least a 10% change in behavior between pre- and post-intervention (assessed using the BREQ-3; (4) a 10% change with the protocol in basic psychological needs assessed using the BPNES pre- and post-intervention.

This protocol may contribute to increase adherence to home exercises in post-stroke patients and help in the change of patients' behavior. The characterization of the sample will be presented through descriptive analysis; the frequency of the practice of household chores, through means and standard deviation and adherence rate to the number of prescribed repetitions (%).

results will allow us to define the protocol and identify the preliminary viability in increasing adherence to the practice of self-administered home exercises, changing behavior and changing basic psychological needs.
