The tilt table test is used in CFS assessment primarily to evaluate:
Answer: Orthostatic intolerance and autonomic nervous system function
The tilt table test measures how the body responds to positional changes, making it useful for diagnosing orthostatic intolerance and autonomic dysfunction in CFS patients.
Functional MRI (fMRI) studies during cognitive tasks in CFS patients typically show:
Answer: Altered or increased activation patterns suggesting compensatory neural recruitment
fMRI studies in CFS show altered or increased activation in brain regions during cognitive tasks, suggesting the brain recruits additional neural resources to compensate for reduced processing efficiency.
The two-day cardiopulmonary exercise test (2-day CPET) in CFS specifically demonstrates:
Answer: Significant decline in performance on the second test day
The 2-day CPET shows a significant decline in peak oxygen uptake and anaerobic threshold on the second test day in CFS patients, providing objective physiological evidence of post-exertional malaise.
EEG (electroencephalography) abnormalities reported in CFS research include:
Answer: Abnormal slow-wave activity and reduced alpha power
EEG studies in CFS have found abnormal slow-wave activity and reduced alpha frequency power, suggesting altered brain electrical patterns consistent with neurological dysfunction.
Quantitative sensory testing (QST) in CFS research is used to measure:
Answer: Sensory thresholds and pain sensitivity
Quantitative sensory testing measures sensory thresholds and pain sensitivity to standardized stimuli, helping identify central sensitization and sensory processing abnormalities in CFS.
Cerebrospinal fluid (CSF) analysis in CFS research has found which of the following in some patients?
Answer: Metabolomic and immune abnormalities compared to healthy controls
CSF studies in CFS have found metabolomic differences and immune abnormalities compared to healthy controls, providing evidence of central nervous system involvement.
Proprioceptive dysfunction in CFS refers to impaired ability to:
Answer: Perceive the position and movement of one's own body
Proprioceptive dysfunction in CFS involves impaired ability to perceive body position and movement, which can contribute to balance problems and coordination difficulties.
