Heterogeneity and Its Impact on Rehabilitation Outcomes and Interventions for Community Reintegration in People With Spinal Cord Injuries: An Integrative Review

Background: Various injury characteristics such as cause, level, severity, and time since injury divide individuals with spinal cord injury (SCI) into many subgroups. The heterogeneity among individuals' injuries and personal characteristics has significant implications for SCI rehabilitation practice, specifically directed toward community reintegration, which is a key goal of rehabilitation interventions for people with disabilities. Purpose: This study aims to summarize the evidence on attributes that make the SCI population heterogeneous, the impact of these attributes on community reintegration, and the implications of heterogeneity for rehabilitation interventions directed toward optimizing community reintegration. Methods: We used an integrative review approach to conduct this study. MEDLINE, PubMed, CINAHL, EMBASE, Google Scholar, and PsycINFO were searched from inception until May 2017. Out of 670 articles retrieved, 49 provided evidence on the impact of various attributes that make SCI heterogeneous on rehabilitation outcomes related to community reintegration. Results: An array of injury-related, personal, social, and environmental factors are associated with various rehabilitation outcomes that affect community reintegration of people with SCI. There is level 1 evidence that social support, self-efficacy, and self-esteem facilitate community reintegration among people with SCI while there is level 5 evidence that presence of psychological or medical complications decreases it. There is lack of clarity on the impact of injury-related factors on community reintegration. Conclusion: This integrative review found that social support and individuals' self-efficacy can improve community reintegration of people with SCI. However, evidence regarding the impact of injury characteristics on community reintegration is still underdeveloped. Approaches directed at community reintegration should involve components of psychosocial, physical, and vocational rehabilitation while considering personal and societal aspects of an individual's life.
