Short Tilte:Ageing with spinal cord injury: Cross-sectional and longitudinal effects
Year, Volume, Issue, Page(s):01, 39, 6, 301-309
Study aimed at separating the cross-sectional and longitudinal components of aging with spinal cord injury (SCI). Cross-sectional effects of age and years post-injury (YPI) were compared to longitudinal change in outcomes for 315 people who underwent SCI prior to 1971. Results indicate that outcomes frequently changed longitudinally without showing any cross-sectional differences. Cross-sectional age was more commonly associated with the worsening of a condition while cross-sectional YPI was commonly associated with improvement. After controlling for cross-sectional effects, psychological measures generally showed minor deterioration, measures of community integration both improved and deteriorated, upper extremity pain increased, lower extremity pain decreased, and participants tended to quit smoking.
