Is Sleep Disordered Breathing Confounding Rehabilitation Outcomes in Spinal Cord Injury Research?

Area of Science:

• Rehabilitation Medicine
• Sleep Science
• Neurology

Background:

• Sleep-disordered breathing (SDB) is highly prevalent in individuals with spinal cord injury (SCI), particularly those with severe lesions.
• Current treatments like continuous positive airway pressure (CPAP) present challenges for adherence in the SCI population.
• SDB negatively impacts physical function and physiological systems crucial for rehabilitation, similar to its effects in the general population.

Purpose of the Study:

• To emphasize the significance of SDB as a potential confounding factor in SCI rehabilitation research.
• To highlight the underdiagnosis and undertreatment of SDB in individuals with SCI.
• To advocate for interdisciplinary collaboration between sleep medicine and SCI rehabilitation research.

Main Methods:

• Literature review and conceptual analysis.
• Discussion of SDB prevalence and impact on physical function in SCI.
• Exploration of potential confounding effects of SDB on rehabilitation research outcomes.

Main Results:

• SDB is frequently undiagnosed and untreated in SCI, despite its high prevalence.
• SDB's known negative effects on physical function suggest it could confound SCI rehabilitation studies.
• No studies were found investigating the direct impact of SDB treatment on physical rehabilitation in SCI.

Conclusions:

• Underdiagnosed SDB in SCI likely confounds physical rehabilitation research, necessitating further investigation.
• There is a critical need for research into the integrated relationship between SDB, its treatment, and physical rehabilitation in SCI.
• The convergence of sleep medicine and SCI rehabilitation research calls for immediate dialogue and collaboration.
