Background  The purpose of this study is to describe feasibility and test–retest reliability of the six-minute walking distance test (6MWD) and an adapted shuttle run test (aSRT) in persons with severe intellectual and sensory (multiple) disabilities. Materials and Methods  Forty-seven persons with severe multiple disabilities, with Gross Motor Function Classification System (GMFCS) grade I and II and wearing a heart rate monitor, performed the 6MWD and the aSRT twice. Results  Ninety-six per cent of the participants completed both tests successfully. Wilcoxon signed-rank test revealed no significant differences between test and retest (P < 0.05). Intraclass correlation coefficients for all variables were ≥0.90. Limits of agreement for aSRT in GMFCS II subjects were insufficient. Conclusion  Six-minute walking distance test is feasible and reliable for measuring functional exercise capacity in GMFCS I and II participants with severe multiple disabilities. aSRT is feasible and reliable for measuring aerobic capacity in GMFCS I participants. Compared with others, participants with severe multiple disabilities achieved poor results in 6MWD.
