A randomized control trial to evaluate a paging system for people with traumatic brain injury.
Although memory problems following acquired brain damage are common, some people are able to compensate for these problems through external aids. It was recently demonstrated that a paging system could reduce the everyday memory and planning problems for people with non-progressive brain injury. The 143 patients who participated in the study comprised several diagnostic groups. This paper reports on the sub-group of people with TBI (n=63). This sub-group was part of the larger sample of 143 already published in the 2001 study. A randomized control cross-over design randomly allocated people to group A (pager first) or group B (waiting list first). Each participant chose their own tasks for which they needed reminders. During a 2 week baseline, successful task achievement was documented. Group A achieved 47.14% of tasks and group B 47.88%. People in group A then received a pager for 7 weeks. During the last 2 weeks of this 7 week period, task achievement was documented again. Group A now achieved 71.80% of tasks and group B (on the waiting list) achieved 49.05% (no different from baseline). Group A then returned their pagers and group B received pagers. During the last 2 weeks of this stage participants were monitored once more. At this point, people in group A had dropped back slightly but were still statistically significantly better than during the baseline (67.23%). Group B, meanwhile, were now achieving 73.62% of tasks. This was statistically significantly better than baseline and significantly better than group A, now in the post-pager phase. It is concluded that this paging system significantly reduces the everyday memory and planning problems of people with TBI.
