Feasibility and Reliability of Two Different Walking Tests in People With Severe Intellectual and Sensory 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.
