National Physical Therapy Examination (NPTE) Practice Exam

Which assessment test should a physical therapist assistant most likely use to assess gait pattern tolerance in an outpatient cardiac patient?

1. Four Square Step Test

2. Performance-Oriented Mobility Assessment

3. Chair stand test

4. Dynamic Gait Index

The correct answer is: Dynamic Gait Index

The Dynamic Gait Index is particularly suitable for assessing gait pattern tolerance in an outpatient cardiac patient because it specifically evaluates an individual's ability to maintain stability while walking under various conditions. This assessment includes tasks like walking while turning the head, walking while changing speeds, and walking over obstacles, all of which challenge the patient's balance and stability. In the context of cardiac rehabilitation, it's important to not only assess the distance or speed but also how different tasks and variabilities impact the patient's gait. Cardiac patients often experience changes in their physical endurance and functional capacity; thus, understanding how their gait responds to various challenges is crucial for developing a personalized rehabilitation program. The other options, while valuable in their respective contexts, do not focus specifically on the various aspects of gait tolerance and balance challenges associated with gait performance. For instance, the Four Square Step Test targets dynamic balance, and the Performance-Oriented Mobility Assessment evaluates overall mobility but lacks the nuanced focus on gait adaptations during ambulation. The Chair Stand Test is primarily centered on lower extremity strength and functional mobility rather than detailed gait mechanics. Consequently, the Dynamic Gait Index stands out as the most comprehensive tool for this purpose.
