Changes in Tissue Oxygen Saturation in Response to Different Calf Compression Sleeves.

Aim. The purpose was to examine the changes in tissue oxygen saturation (StO2) in response to the application of different commercially available calf compression sleeves. Methods. Eight subjects came to the laboratory to complete a session in seated position including 10 min of quiet rest followed by 3 min measuring calf StO2 without compression sleeves and then alternating of 3 min of passive rest and 3 min measuring StO2 with calf compression sleeves. A total of 15 different commercially available compression sleeves were studied in a randomized order. Calf StO2 was recorded using near-infrared spectroscopy. Results. StO2 was significantly increased with all compression sleeves (p < 0.05) compared with no compression (from +6.9% for the least effective to +22.6% for the most effective). Large differences were observed between compression sleeves (p < 0.05). StO2 was positively correlated with compression pressure (p < 0.05; r = 0.84). Conclusion. This study shows that wearing compression sleeves from various brands differently affects tissue oxygen saturation. Differences were linked to the compression pressure: higher compression pressures were associated with higher StO2.
