Subjects' overall response to treatment in posttest 1 demonstrated a significant improvement as compared with the pretest (p < .005). Fourteen subjects showed improvement, with gains in 10 subjects greater than one standard deviation. Only 4 subjects improved greater than one standard deviation in posttest 2 compared with the pretest. Mean subject response to treatment in posttest 2, however, did not show significant improvement. When the variables were grouped into the three categories described previously, two of those categories showed significant improvements in posttest 1: force walking aid data (p < .01) and knee motion data (p < .005). Eight individual variables within those two categories showed statistically significant improvement. Given measurement error, however, these improvements were not clinically significant. No significant gains were seen in the three categories of variables for posttest 2 when compared with the pretest.
