Effect of instrument-assisted soft tissue mobilization combined with blood flow restriction training on function, pain and strength of patients with patellofemoral joint pain

Table 6 Results of the comparison of the changes in test values with the mean values at three time points of the Lysholm rating scale

	Before treatment	After the first treatment	After 4 weeks of treatment	Multiple are comparable
	M ± SD	M ± SD	M ± SD	Multiple are comparable
Test group	61.62 ± 12.64	82.77 ± 18.75^*&α	84.08 ± 9.71^*#&α	Before treatment < after the first treatment < after 4 weeks of treatment
Control group	70.85 ± 17.20	86.00 ± 11.05^*&α	94.54 ± 7.23^*#&α	Before treatment < after the first treatment < after 4 weeks of treatment

Tables were analysed using repeated measures ANOVA
^*Represents significant difference in change in Lysholm score compared to pre-treatment (p < 0.05)
^#Represents significant change between test and control groups (p = 0.005)
^&Represents no significant change in comparison between time points within groups (p > 0.05)
^αRepresents a significant change between after the first treatment and after 4 weeks of treatment (p < 0.05; M ± SD indicates mean ± standard deviation
