How can endurance and fatigue be assessed in individuals with cerebral palsy?

• A. Endurance cannot be assessed.
• B. By testing functional tasks related to patient-specific goals, such as ambulation in a school setting.
• C. Only cardiovascular tests.
• D. Fatigue is not relevant.

Answer: (B)

Endurance and fatigue in cerebral palsy are best understood through functional performance in meaningful tasks. Because CP often affects movement efficiency, spasticity, balance, and motor control in ways that vary across activities, the most informative assessment is how long a person can sustain a task that matters to them in real life. Testing functional tasks aligned with patient goals—such as walking in a school setting, negotiating stairs, or moving between classrooms—shows how endurance translates to participation and daily life, and how fatigue limits that participation. You can gather practical data by measuring distance or time for a typical route, observing pace, and noting how effort, fatigue, or performance change over the task. Supplementary measures like perceived exertion or simple physiological indicators can add context, but the key idea is to anchor endurance evaluation in activities the person needs to perform. This approach recognizes that relying solely on isolated cardiovascular tests may not reflect everyday endurance, and it reinforces that fatigue is a relevant, impactful factor in CP.
