Which type of information is least relevant to document during a session?

Documenting a patient's personal hobbies during a therapy session is the least relevant type of information, as it typically does not directly relate to the assessment of their physical therapy progress or treatment outcomes. The primary focus of documentation in physical therapy is to record information that influences the patient's care, such as their subjective complaints, which provide insight into their symptoms and experiences; objective measures of progress, which quantify improvements or declines in their physical abilities; and the specific treatment interventions applied, which detail the methods used to facilitate recovery.

While understanding a patient's personal interests can enhance rapport and potentially inform treatment approaches, it does not impact the clinical decision-making process or demonstrate progress in therapy. Hence, prioritizing documentation that supports clinical goals and tracks therapeutic outcomes is essential.
