Objective:

Cognitive difficulties in Multiple Sclerosis (MS) are important contributors to impairment in instrumental activities of daily living. A non-randomised controlled trial was conducted to explore the effects of a cognitive rehabilitation protocol on MS patients' daily life functionality.

Participants and Methods:

Seventy-five relapsing-and-remitting MS patients were recruited. Intervention Group (IG, n=31) underwent 16 individual rehabilitation sessions (1hx2/week; weeks 2-10), which included paper and pencil cognitive stimulation exercises and training memory strategies and external memory aids; and a booster session (week 37). Control Group (CG, n=44) received care as usual. These primary outcome measures were applied at baseline and at weeks 11, 36, and 62: Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ), Mental Slowness Questionnaire (MSQ), Mental Slowness Observation Test (MSOT), and Sydney Psychosocial Reintegration Scale-2 (SPRS-2). Score differences from baseline were calculated for all measures and follow-up time points except for SPRS-2, which was only applied twice (baseline and week 62). Linear regressions fitted with generalized estimating equations (GEE) were performed to verify the effects of time and group on the outcome measures. Baseline scores were included in the model as covariates for all outcome measure except SPRS-2. Chi-square and Mann-Whitney tests were applied to compare demographic and clinical characteristics of the groups.

Results:

Groups had similar demographic (i.e., sex, age, and education) and clinical (i.e., age at disease onset, disease duration, disease modifying treatments, and Expanded Disability Status Scale score) characteristics. IG's MSQ score progressively improved, whereas CG's score did not change from baseline (group x time effect: p<0.001) throughout follow-up. IG's MSNQ score improved from baseline at weeks 11 and 36, but not at week 62. CG's MSNQ score did not change from baseline throughout follow-up (group x time effect: p=0.025). Both IG's and CG's performance on the MSOT improved (time effects). Though, the IG showed greater improvement at follow-up (group effects) on MSOT score and time (both p<0.001). IG's SPRS-2 improved, whereas CG's score declined (group x time effect: p<0.001).

Conclusions:

Combining restorative techniques with strategy-based compensatory techniques may produce significant and persistent effects on MS patients' self-reported everyday functioning and on their objective performance of instrumental tasks.
