Background/objective: Autonomic dysreflexia (AD) is a potentially life-threatening complication of spinal cord injury (SCI) characterized by episodic paroxysmal hypertension and bradycardia in response to a noxious stimulus below the level of injury. Recognition of AD is crucial for individuals with SCI and their family members to facilitate timely and appropriate management. The objectives of this study were to (a) evaluate knowledge of AD among SCI consumers and their family members and (b) identify the preferred format and timing of education regarding AD recognition and management for these stakeholders.

This paper presents the results of a 2-year mixed methodology (quantitative and qualitative) study examining the reintegration and quality of life of community-residing adults with spinal cord injury (SCI). A convenience sample of 100 individuals with SCI completed three questionnaires for the quantitative study phase. A self-selected subsample of 34 of the participants then attended qualitative focus groups to further explore adjustment to living in the community after SCI.
