Abstract

Purpose: There is a pressing need for safe venous thromboembolism (VTE) prophylaxis in orthopedic patients with the highest risks of both venous thrombosis and bleeding. Portable intermittent pneumatic compression device (IPCD) has proven to be effective and safe in patients with a high risk of venous thrombosis and low bleeding risk. Therefore, this study examined the effectiveness, safety, and wearing compliance of portable IPCD for postoperative VTE prophylaxis in patients with the highest risks of both venous thrombosis and bleeding.Methods: The cases consisted of 38 patients who had used a portable IPCD and had the highest risks of both venous thrombosis and bleeding. We examined the incidence of VTE to assess the effectiveness of the portable IPCD, the presence of hemorrhagic adverse events to assess safety, and the wearing rate to assess wearing compliance.Results: The incidences of asymptomatic and symptomatic deep vein thrombosis were 5.3% and 2.6%, respectively. The incidence of hemorrhagic adverse events was 21.1% in patients who received anticoagulants and wore an IPCD simultaneously and 0% in patients who wore an IPCD but did not receive anticoagulants. The wearing rate (i.e. ≥18 h/day) was 100%.Conclusion: Portable IPCD has the potential for safe VTE prophylaxis in patients at high risks for both venous thrombosis and bleeding. Therefore, we suggest that such patients use a portable IPCD for VTE prophylaxis.

Abstract

Tissue flossing aims to improve range of motion (ROM), reduce pain, and enhance injury prevention. However, evidence is lacking regarding its effects. Therefore, this study examined the effects of flossing on hamstring muscles function in comparison to dynamic stretching (DS). Seventeen healthy young men ([mean ± SD] age, 23.2 ± 1.1 years; height, 1.72 ± 0.08 m; body mass, 63.5 ± 9.3 kg) volunteered as subjects in this randomized crossover trial. The subjects received flossing, DS, and control interventions in random order at least 1 week apart to eliminate the influence of the previous intervention. Flossing involved passive twisting and active movement using a floss band (Sanctband COMPRE Floss Blueberry, Sanct Japan Co., Ltd.). DS was performed for 4 minutes in 30-second sets consisting of 15 repetitions of 2 seconds stretching. The following were measured before and after each intervention: straight leg raise (SLR) test, passive knee extension (KE) test, passive torque, passive stiffness, fascicle length in the biceps femoris long head as an indication of hamstring muscles flexibility, and maximal isometric knee flexion contraction, maximal eccentric knee extension/flexion contraction, rate of force development, and muscle activity. Flossing yielded significant improvements in the SLR test (mean difference in post-intervention changes between interventions: 5.4°, percentage change from pre- to post-value: 13.4%, p = 0.004), passive KE test (6.2°, 4.5%, p < 0.001), passive torque at end-ROM (3.8 Nm, 4.7%, p = 0.03), and maximal eccentric knee flexion contraction (14.9% body weight, 8.2%, p = 0.03) than control. Moreover, flossing yielded 2.1-fold greater improvements in the passive KE test (3.8°, 4.5%, p = 0.03) and yielded significant improvements in the maximal eccentric knee extension contraction (29.9% body weight, 13.8%, p = 0.02) than DS. Therefore, flossing on hamstring muscles is more beneficial than DS with respect to increasing ROM and muscle exertion., (© Journal of Sports Science and Medicine.)
