Available Screening Tools for Detecting Potential Complications from Rehabilitation in People Living with Long COVID

Name of Assessment or Screening Tool	Brief Description of Screening Tool	Resources
DePaul Symptom Questionnaire – Post-Exertional Malaise (DSQ-PEM)	This is a brief, standardized questionnaire that aims to detect experiences with post-exertional malaise [16].	May be downloaded and used free of charge from: https://csh.depaul.edu/about/centers-and-institutes/ccr/myalgic-encephalomyelitis-cfs/Pages/measures.aspx
10-Minute NASA Lean Test	Positional test that assesses for postural orthostatic tachycardiasyndrome.	Instructions are available from: https://solvecfs.org/wp-content/uploads/2021/07/10-Minute-NASA-Lean-Test-Clinicians.pdf
Pulse Oximetry	Pulse oximetry under clinical supervision has been recommended to screen for exertional desaturation using tests such as the 1-minute sit-to-stand test [2], the 40-step walk test [15], or during home observation. A drop in pulse oxygen saturation of more than 3–4% from baseline or to 94% or below is considered desaturation [2]. Exercise testing for exertional desaturation should be avoided or modified (within tolerable limits for the individual) in the presence of Post-Exertional Symptom Exacerbation.	Pulse oximeter is required. Rapid exercise tests for exertional desaturation are not recommended for use outside a supervised care setting if resting pulse oximeter saturation is < 96% [15].
Adapted Autonomic Profile (aAP)	The adapted Autonomic Profile (aAP) is a home-based test for the evaluation of neuro-cardiovascular autonomic dysfunction. This screening test may clarify the relationship between symptoms and common triggers in daily life, informing self-management and rehabilitation of episodic conditions such as Postural Orthostatic Tachycardia Syndrome.	The test involves measuring blood pressure and heart rate at various times throughout the day while at home. Detailed instructions for conducting the aAP have been published [17].
