PEDro=6

NInitial=74, NFinal=59

Population: CVA=23, Infection=3, TBI=33, Tumor=10, Missing=1. Control First (n=34): Mean Age=50.18 yr; Gender: Male=23, Female=11; Mean Time Post Injury=8.62 yr. Assisted Intention Monitoring (AIM, n=36): Mean Age=46.36 yr; Gender: males=23, females=13; Mean Time Post Injury=4.89 yr.

Intervention: Participants were randomized to receive AIM or control first. In the AIM-first group, participants received goal management training followed by text messages for improving achievement of everyday intentions. Control-first group received brain injury information, Tetris game, and non-informational text messages. After 3 wk, participants were crossed over with AIM-first group receiving usual care and control-first group receiving AIM.

Outcome Measures: Mean daily proportion of intentions achieved, Achievement of all goals excluding the phone call task, Profile of Mood States total mood disturbance (POMS MD), Hotel Task, Verbal Fluency.

1.        Participants achieved a greater proportion of intentions during the AIM intervention relative to control (p=0.040).

2.        Participants achieved a greater proportion of goal attainment (without the phone call task) during the AIM intervention relative to control (p=0.033).

3.        No significant Group x Time interaction effect was found for the POMS MD or Hotel Test.

4.        When only comparing group differences at post-intervention phase 1, intention to treat analysis showed no significant difference between groups for proportion of intentions achieved or achievement of goals excluding the phone task.

NInitial=27, NFinal=24

Population: TBI=16, Subarachnoid hemorrhage=3, Other=5; Mean Age=45.14 yr; Gender: Male=22, Female=2; Mean Time Post Injury=5.53 yr; Severity: severe.

Intervention: Participants were randomly assigned to the experimental (n=10) or control group (n=14), and assessed before (baseline), during, and after intervention (return to baseline). Experimental group participants received Guide, an audio-verbal interactive micro-prompting software designed to emulate the verbal prompts and questions provided by carers or support workers. Control group participants received rehabilitation as usual.

Outcome Measures: Morning Checklist (number of support worker prompts, number of safety critical and general errors, deviations from and repetitions of the necessary sequence), Satisfaction score (5-point scale).

1.        Compared to baseline, there was a significantly greater reduction in the intervention group than the control group during (p<0.010) and after (p<0.010) the intervention for the number of prompts needed.

2.        There were no significant differences between groups across the three phases in terms of number of errors, sequence errors, or satisfaction scores.

PEDro=8

N=42

Population: TBI; Mean Age=33.5 yr; Gender: Male=26, Female=16; Mean Time Post Injury=9.2 yr.

Intervention: Participants were randomly allocated to either the experimental group (EG; n=21), who received 8 weeks of training in the use of a personal digital assistant (PDA) with an occupational therapist, or the control group (CG; n=21) who received 8 weeks of traditional occupational therapy. Training sessions for the EG focused on PDA training for application and organization into everyday life.

Outcome Measures: Goal Attainment Scale (GAS), Memory Functioning Questionnaire (MFQ) and Memory Compensation Questionnaire (MCQ).

1.        There was a significant difference between EG and CG groups in the functional memory failures subset of the GAS (p=0.0001); however, the total GAS score was not significant between groups (p=0.165).

2.        The caregiver report on the frequency of forgetting and retrospective memory subset of the MFQ were significant between groups (p=0.021, p=0.042 respectively); however, seriousness of forgetting and mnemonic usage subset of the MFQ were not significant between groups (p=0.455, p=0.301 respectively)

3.        Internal strategies subset of the MCQ was significant between groups (p=0.021); however, external strategies subset of the MCQ was not significant between groups (p=0.580).

PEDro=7

N=29

Population: TBI=23, ABI=6; Mean Age=42.31 yr; Gender: Male=17, Female=12; Mean Time Post Injury=13.59 yr.

Intervention: Patients were assigned to either the systematic instruction group (n=15) or the conventional group (control; n=14). The systematic group was based on direct instruction and mastery, rather than exploratory learning (e.g., errorless learning). The control group received conventional, trial and error learning (e.g., errorful learning). Participant’s sessions targeted selected skills on a personal digital assistant (PDA; Palm Tungsten E2). All participants received 12 sessions (45 min, 2-3 x/wk for 4-6 wk).

Outcome Measures: Assessment of PDA skills, California Verbal Learning Test II-Short Form, Wechsler Memory Scale III (Logical Memory, Visual Reproduction), Controlled word Association Test, Trail Making A and B.

1.        Those receiving systematic instruction performed significantly more (p<0.01) correct tasks at the 30-d follow-up compared to participants receiving the conventional instruction.

2.        Those receiving systematic instruction also performed the correct tasks more quickly (16 sec) than the conventional instruction group (41.15 vs 57.73 sec, p=0.050).

3.        Fluency scores (ability to follow through with a task) were also found to be higher in those in systematic instruction group compared to those in the conventional instruction group at 30 d follow-up (p=0.050).

4.        There was no statistically significant main effect on treatment condition for content generalization.

5.        Overall systematic instruction resulted in better environmental generalization compared to trial and error learning (p<0.050) at post-test, but not 30d follow-up.

Population: TBI patients: Mean age: 42.1 yr (Age Range: 16-66 yr); Gender: male=17, female=19;

Intervention: Participants were trained on how to use two Personal Digital Assisant devices (Palm OS and Microsoft OS device) to assist them in organizing activities that needed to be completed throughout the week.

Participants were randomly assigned to four memory aid conditions (Palm OS, Microsoft OS, Combined Baseline, or paper organizer) in a crossover fashion.

Outcome Measure: Timely completion rates.

1.        When using the PDAs, the individuals had a higher task completion rate than when they used paper memory aids (Palm OS: p<0.005; Microsoft OS: p<0.001).

2.        Results also indicated that those using the Palm OS PDA had a higher completion rate than those using the Microsoft OS PDA (p<0.0005).

PEDro=5

N=23

Population: Group A (n=12): Mean age=47.17 yr, mean time post-injury=9 yr; Group B (n=11): Mean age=47.55 yr, Mean time post-injury=12.45 yr.

Intervention: Patients were randomly assigned to group A or group B. In group A participants were assigned to use the Television Assisted Prompting (TAP) system, which gave them personalized task reminders through their television, in the crossover phase participants used their own typical practice (TYP) strategies of remembering what tasks they had to complete. In group B participants started with the TYP phase, and then at crossover used the TAP system.

Outcome Measures: Task completion.

1.        No significant differences were found between groups A or B; therefore, data from the two groups was collapsed.

2.        Task completion was significantly better when participants used the TAP condition (72%) versus the TYP condition (43%).

3.        In the TAP condition participants completed significantly more experimental tasks compared to either preferred (p=0.01) or non-preferred tasks (p=0.01).

Population: Mean age=41.5yr; Gender: Male=11, Female=2; Injury severity: mean GCS=6.6; Mean time post injury=11 yrs.

Intervention: Each individual received a Windows Phone (version 7.5) for 6-weeks and was asked to use this as their only memory strategy. Five group sessions (1.5 hrs each) were held to help ensure each individual knew how to use the applications on each phone (calendar, reminders, etc.). After the 6-week intervention period a 2-week break was taken to assess all behaviors and then a 6-week follow-up assessment was completed.

Outcome Measures: Prospective Memory Questionnaire (PMQ), Prospective and Retrospective Memory Questionnaire, Cognitive Failures Questionnaire (CFQ), European Brain Injury Questionnaire (BIQ), Hospital Anxiety and Depression Scale (HADS).

1.        Pre- to post-intervention the PMQ (p=0.005) and the Prospective and Retrospective Memory Questionnaire (p=0.014) revealed a significant decrease in the number of self-reported memory problems.

2.        No significant effects were found on common brain injury deficits through the BIQ and CFQ.

3.        No significant effects on mood were reported through the HADS or QoL scale.

4.        When comparing reports from baseline to 6-week follow-up, significant effects on memory and self-reported errors were seen on PMQ (p=0.009), the Prospective and Retrospective Memory Questionnaire (p=0.014), and the CFQ (p=0.000).

Population: Age Range: 19-60 yr; Gender: Male=15, Female=5; Condition: TBI=14, Other=6.

Intervention: Participants were trained to associate the text message ‘STOP” with a cue for participants to stop and think about what needed to be done, what they were doing etc. Participants were asked to make telephone calls at specific times of the day for a 3-week period.  Over the 3-week period on 5 randomly selected days a text message “STOP” was sent to participants.

Outcome Measure: Completion of task.

1.        During the first week 15% of the participants failed to make the calls.

2.        The effect of cueing on participants had a significant impact on the number of calls made (p<0.001).

3.        Participants made 87.6% of calls when cued but only 71.2% of calls when they were not cued.

4.        Of note there was a positive relationship between the number of calls made (completed) and the time in which they were made (within 5 minutes of the target time).
