Offloading effects of a removable cast walker with and without modification for diabetes-related foot ulceration: a plantar pressure study

Table 4 Comparisons between conditions for peak pressure (N = 16)

Comparison	Mean difference in peak pressure (kPa)^a	95% CI	P-value	% difference between conditions^b
Control – RCW	252.7	150.5 to 354.8	< .001	65.4% decrease
Control – RCW with felt to orthosis	291.6	189.4 to 393.7	< .001	75.4% decrease
Control – RCW with felt to foot	321.4	208.4 to 434.4	< .001	83.1% decrease
RCW – RCW with felt to orthosis	38.9	-17.9 to 95.7	.331	29.1% decrease
RCW – RCW with felt to foot	68.8	8.4 to 129.1	.021	51.3% decrease
RCW with felt to orthosis – RCW with felt to foot	29.8	6.5 to 53.2	.009	31.4% decrease

^aMean difference equates to the peak pressure of the first condition listed minus the peak pressure of the second condition listed
^bA decrease in percentage indicates that the latter condition recorded a lower mean than the former condition
