OBJECTIVE: To synthesize the evidence for differences in cognitive motor
interference (CMI) between persons with multiple sclerosis (MS) and those without
MS by using systematic review and meta-analysis. DATA SOURCES: EMBASE, PubMed,
ScienceDirect, Scopus, SPORTDiscus, and Web of Science. Our focused literature
search was informed by past systematic reviews of CMI during walking in MS. STUDY
SELECTION: The key terms searched included Multiple sclerosis and synonyms of
motor function (eg, Gait disorders, Gait, Walking, Balance, or Fall) and motor
and cognitive functions (eg, Cognitive motor interference or Thinking). DATA
EXTRACTION: From the 116 abstract-identified articles, 13 experimental studies
were selected for the final analysis and were rated using the Quality Assessment
of Diagnostic Accuracy Studies tool. A meta-analysis was performed for all
considered outcomes. DATA SYNTHESIS: The results yielded a small overall effect
size (ES) of .08 (SE=.17; 95% confidence interval, -.25 to .40; z=.49; P>.05),
which indicated a nonsignificant minimal difference in CMI between persons with
MS and those without MS. The moderator analysis for motor task (mobility task:
ES, .22; postural task: ES, -.11) was not significantly different between persons
with MS and those without MS. The moderator analysis for cognitive task (verbal
fluency task: ES, .66; mental tracking task: ES, .04; discrimination and
decision-making task: ES, -.30) resulted in a significant difference in CMI
between persons with MS and those without MS (P<.05). CONCLUSIONS: We provide
evidence that overall there is a minimal difference in CMI between persons with
MS and those without MS.
