The effect of MIR on fatigue was more pronounced in the subgroup of “mild” (mean change -0.8± 1.4; p = 0.001) as compared to the subgroup with “moderate to severe” walking impairment (mean change -0.5±1.0; p = 0.032) resulting in a strong trend towards a statistical significant difference between the subgroups at the end of MIR (p = 0.051).
