Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This cross-sectional prospective study will assess the potential association of more severe sleep apnea after spinal cord injury with more intense neuropathic pain, more severe spasticity, and more significant cardiovascular abnormalities including cardiac arrhythmias and blood pressure fluctuations. In addition, the participants' experience when undergoing home-based sleep screening test or hospital-unattended sleep screening test will be assessed in a semi-structured interview.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This cross-sectional prospective study will assess the potential association of more severe sleep apnea after spinal cord injury with more intense neuropathic pain, more severe spasticity, and more significant cardiovascular abnormalities including cardiac arrhythmias and blood pressure fluctuations. In addition, the participants' experience when undergoing home-based sleep screening test or hospital-unattended sleep screening test will be assessed in a semi-structured interview (qualitative analysis).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Individuals without sleep apnea after spinal cord injury

No significant sleep apnea is defined as an apnea-hypopnea index (AHI) \< 5 events per hour of sleep

Home-based sleep screening test or hospital-unattended sleep screening test

Intervention Type DEVICE

ApneaLink device will be used to assess the number of apnea and hypopnea events per hour of sleep.

Cardiovascular beat-to-beat monitoring

Intervention Type DEVICE

CareTaker device will be used to continuously record the participant's arterial blood pressure and heart rate during sleep.

ECG monitoring

Intervention Type DEVICE

Faror Bithium 180 device will be used to continuously record the participant's ECG during sleep.

Individuals with mild sleep apnea after spinal cord injury

Mild sleep apnea is defined as an apnea-hypopnea index (AHI) ≥ 5 events per hour of sleep, but an AHI \<15 events.

Home-based sleep screening test or hospital-unattended sleep screening test

Intervention Type DEVICE

ApneaLink device will be used to assess the number of apnea and hypopnea events per hour of sleep.
