Which of the following professionals would be most likely to help a patient relearn how to tie his shoes after a car accident?

The most suitable professional for helping a patient relearn practical skills, such as tying shoes after a car accident, would be an occupational therapy assistant. This role specifically focuses on assisting individuals in regaining daily living skills and improving their ability to perform everyday tasks after injuries or impairments.

Occupational therapy combines therapeutic exercises and activities aimed at enhancing a person's functional abilities and independence. An occupational therapy assistant works under the supervision of an occupational therapist to implement treatment plans that address motor skills, coordination, and cognitive functions required for various activities, including self-care tasks like tying shoes.

In contrast, while a clinical psychologist may address emotional and psychological aspects related to the accident and recovery process, they would not focus on the physical skills necessary for tying shoes. Similarly, a health psychologist typically deals with the psychological impact of health issues and promotes healthy behaviors but does not directly work on rehabilitative skills. A behavior analyst would focus on modifying behaviors through techniques like applied behavior analysis, which might not directly apply to relearning motor skills for activities of daily living.
