Final answer:
The purpose of functional assessment in rehabilitation services is to set rehabilitation goals by evaluating a patient's capabilities in strength, balance, and endurance to create a tailored rehabilitation program.
Step-by-step explanation:
The purpose of the functional assessment in rehabilitation services is primarily to set rehabilitation goals. This is a critical step taken by professionals such as physiotherapists, who work to improve physical functioning and reduce functional impairments. Through the assessment process, the capabilities of a patient are evaluated in terms of strength, balance, and endurance. Understanding the patient's current level of function facilitates the creation of an individualized program designed to enhance these capabilities. Moreover, professionals may use equipment like crutches to aid in recovery, so assessing the patient's use of equipment is also an essential part of the functional assessment to determine whether patients can safely and effectively use these aids as they regain their functional abilities.
