Participation in Social and Community Life Before and After Spinal Cord Injury/Disease: Factors Influencing Changes in Short-Term and Long-Term Participation.

Objectives: Examining changes in participation frequency (productive, leisure, and social activities) from pre-spinal cord injury/disorder to at least 2 yrs post-spinal cord injury/disorder and identifying sociodemographic and spinal cord injury/disorder characteristics associated with significant shifts in participation frequency.

Design: The study used a longitudinal design, using data from the Swiss Spinal Cord Injury Cohort study. Pre-spinal cord injury/disorder participation frequency was assessed retrospectively 12 wks after spinal cord injury/disorder and prospectively 1 and at least 2 yrs after spinal cord injury/disorder. Linear mixed-effects model trees were used to identify subgroups with participation changes and related sociodemographic and spinal cord injury/disorder characteristics.

Results: The study involved 550 individuals (median age at spinal cord injury/disorder onset: 53 yrs, 30% female, 63.9% with traumatic etiology, and 5.6 yrs since onset). Pronounced decrease was observed prominently in productive activities. Education and age at spinal cord injury/disorder onset served as initial variables to split the tree at first level for each of the participation dimensions.

Conclusions: This research identified participation dimensions most susceptible to changes during the initial years after spinal cord injury/disorder and pinpointed subgroups displaying clinically meaningful longitudinal variations across productive, leisure, and social activities. These findings have the potential to enhance the efficiency of rehabilitation programs, leading to improvements in long-term participation levels for individuals with spinal cord injury/disorder.
