How Outcome Measurement Tests Benefit Physical Therapy

Can individuals experiencing difficulty with functional mobility benefit from physical therapy to help them return to normal activities?

Outcome Measurement Tests

Outcome measurement tests assess the effects of a treatment plan on a patient. They can be used to determine a patient’s baseline function, monitor their progress, and evaluate the effectiveness of treatment. They also give the therapy team an effective way to measure mobility, flexibility, and range of motion.

Function and Purpose

Outcome measurement tests serve various purposes. These include: (American Physical Therapy Association, N.D.)

• To assist in goal-setting
• Provide motivation
• To guide treatment
• To give a prognosis for the specific condition
• To justify the treatment

The physical therapist may use other functional outcome measurements to help assess physical therapy progress.

• They may measure your strength and range of motion.
• Balance and posture may be evaluated.

Effective functional outcome measurement tests must meet certain criteria to be useful in a physical therapy clinic. First, they must be reliable, meaning the results must be consistent with each patient and within groups of patients. They must also be valid to measure exactly what they are intended to measure. An effective measurement test must also be easy to administer, so it must be practical and simple. Outcome measurement tests must also be purposeful. For example, a balance test must reflect a patient’s current function and be related to their balance ability.

Common Outcome Measurement Tests Used

Common functional outcome measurement tools that a physical therapist may use include:

• The timed up-and-go or TUG test is a simple assessment used to evaluate a person’s mobility and balance by measuring how long it takes them to stand up from a chair, walk a short distance, turn around, walk back, and sit down again; it’s often used to identify potential fall risks in older adults, particularly those with mobility concerns, as a longer time to complete the task may indicate increased fall risk. (Centers for Disease Control and Prevention, 2017)
• The Tinetti balance and gait evaluation, also known as the Performance-Oriented Mobility Assessment (POMA), is a clinical test used to assess balance and gait abilities, particularly in older adults. It evaluates stability during various standing and walking tests and provides a score that indicates a person’s fall risk potential.
• The Berg Balance Scale (BBS) is a standardized test for adults that measures balance and the risk of falling. It’s widely used and can be performed in various settings.
• The six-minute walk test (6MWT) is a medical assessment in which a person walks as far as they can in a designated area for exactly six minutes. This allows healthcare providers to evaluate their functional exercise capacity. It is particularly useful for assessing patients with lung or heart conditions where walking ability might be compromised. The distance covered during the six minutes is the key measurement used to interpret the test results. (Ferreira M. B. et al., 2022)
• The functional reach test (FRT) is a clinical assessment that measures an individual’s dynamic balance by determining the maximum distance they can reach forward while standing in a fixed position. It assesses their risk of falling by evaluating how far they can extend their arm before losing stability. The FRT is often used to assess older adults or individuals with potential balance issues. 
• The Oswestry low back pain disability questionnaire is a self-administered questionnaire used to measure the level of disability a person experiences due to low back pain. It assesses how the pain impacts their daily activities in various aspects of life, such as personal care, work, and social life; a higher score indicates greater disability. 
• The functional independence measure (FIM) assesses a patient’s ability to perform daily activities independently. It also measures the patient’s disability level and how much assistance is needed.

Functional outcome measurement tests provide a starting point for developing physical therapy goals. For example, if the TUG test takes 19 seconds, individuals may aim for 10 seconds. A TUG score that falls at or over 10 seconds indicates reduced physical capacity (Kear B. M., Guck T. P., & McGaha A. L. 2017). This can be the motivation needed to reach physical therapy goals.
