Conclusion : Combinations of peri- and post-injury factors appear to be influential in the development of PTSD among persons with SCI .
Objectives : To summarise quantitatively the available evidence relating to pretraumatic , peritraumatic and posttraumatic characteristics that may increase or decrease the risk of developing posttraumatic stress disorder ( PTSD ) following spinal cord injury ( SCI ) .
A comparison of posttraumatic stress disorder in veterans with and without spinal cord injury.
The authors assessed effects of  paraplegic and quadriplegic spinal cord injuries ( SCIs )  on posttraumatic stress disorder ( PTSD ) by comparing severity and prevalence of PTSD in these groups to a sample of controls who experienced traumatic injuries other than SCI . The authors found that veterans with quadriplegia reported significantly less severe current PTSD symptoms than controls who were not significantly different from veterans with paraplegia . These results suggest that sustaining a quadriplegic SCI decreases risk of current PTSD , whereas sustaining a paraplegic SCI is associated with greater risk of PTSD , although the risk is no greater than that incurred from experiencing the trauma itself
