Step-by-step explanation:
The portion of a progress note that includes an Occupational Therapist's (OT) clinical reasoning regarding client performance is the Assessment section.
In this section, the OT will analyze the client's progress, identify strengths, limitations, and areas that require further intervention. They may also provide a summary of the client's response to therapy, treatment plans, and recommendations for future interventions.
