RESUMEN
STUDY DESIGN: Prospective cohort. OBJECTIVES: To characterize spinal cord injury (SCI)-related pain and treatment in victims of the 2008 Sichuan earthquake. SETTING: Mianzhu County, China. METHODS: Twenty-six patients who sustained SCI in the 2008 Sichuan earthquake and who were treated in the same hospital were enrolled. Data was collected on pain severity with a visual analog scale, depression with Patient Health Questionnaire-9, quality of life (QoL) with World Health Organization Quality of Life-BREF and social participation with the Craig Hospital Handicap Assessment and Reporting Technique Short Form at three assessment points. Detailed pain descriptions including therapeutic interventions were elicited at the fourth assessment. Pain determinants were analyzed with a longitudinal Tobit regression, and Pearson's correlations of pain severity with depression, QoL and social participation stratified by measurement point were calculated. RESULTS: SCI-related pain was highly prevalent and prevalence of neuropathic pain was nearly twice that of nociceptive pain. Most patients reported pain since the onset and severity was not significantly reduced over time. Cervical injury, complete lesions and education level were significant pain determinants. Depression and QoL scores were highly correlated with pain at the first two assessments points but not at the third measurement. Most patients did not seek treatment because they regarded pain as either a normal condition after SCI or were afraid of drug dependency. CONCLUSION: This initial longitudinal assessment and characterization of SCI-related pain in earthquake victims provides a foundation for further exploration of the biological and psychosocial determinants of pain severity and of the correlation of chronic pain with other outcomes of interest in this population. Patient pain-treatment-seeking behavior and therapeutic interventions should be evaluated concurrently.

STUDY DESIGN: Narrative literature review. OBJECTIVES: To (1) summarize epidemiological and scientific research on spinal cord injury (SCI) populations from three severe earthquakes (EQs) in rehabilitation resource-scarce settings; (2) summarize SCI rehabilitation services by local and foreign providers in response to these EQs and (3) provide implications including research gaps for a supporting global scientific research agenda. SETTING: International. METHODS: A literature review was conducted using PubMed to identify epidemiological studies reporting data on SCI survivors of the 2005 Kashmir EQ in Pakistan, the Sichuan EQ of 2008 in China and the 2010 Haiti EQ. A follow-up review on the SCI rehabilitation services provided by local and foreign providers in response to these EQs was also performed. RESULTS: Review of the scientific literature revealed the qualitative trends in focused EQ victim epidemiological data, including SCI classification and types of medical complications. Selected EQ country narratives showed that post-disaster SCI rehabilitation services were expanded by adapting local resources with international assistance to manage the significant numbers of SCI survivors. The resulting SCI research was limited. CONCLUSION: A global disaster research agenda for SCI in EQs in rehabilitation resource-scarce settings is needed to strengthen the evidence base for improvement of clinical management and outcomes for SCI EQ survivors. Expansion of this limited narrative review into a systematic review to identify additional research gaps is a proposed next step. Effective disaster setting data management and research collaborations of foreign and local SCI disability and rehabilitation stakeholders will be required for agenda implementation.
