Figure 4.

The CPM response at the precompression baseline and after 3 compression protocols. (A) Overall, no significant difference was found between the pre- and post-compression CPM assessment. However, the CPM was more efficient after the MEDIUM protocol as compared with the SMALL protocol. (B) For males, lower CPM efficiency was observed following the SMALL as compared with the MEDIUM compression protocols; for females, similar CPM responses were denoted across all conditions. (C) For males, the CPM efficiency was reduced from the baseline following the SMALL as compared with the changes in CPM efficiency following the MEDIUM protocol. *P ≤ 0.05. CPM, conditioned pain modulation; SMALL, compression area up to the ankle; MEDIUM, compression area up to the knees; LARGE, compression area up to the hip joint.
