Replication Data for: CRET on the elbow

Introduction. Lateral elbow tendinopathy, or “tennis elbow”, is a pathology that affects around 1.3% of the general population. Capacitive-resistive electric transfer therapy is aimed to provoke temperature and current flow changes in superficial and deep tissues. The aim of this in vitro study was to analyze the thermal behavior and the transmission of electric current on the superficial and deep tissues of the elbow, during the application of the different modalities of a capacitive-resistive electric transfer treatment protocol for chronic elbow tendinopathy. Methods. A cross-sectional study designed, five fresh cryopreserved cadavers (10 elbows) were included in this study. A 30-minutes intervention was performed based on a protocol commonly used in clinics for the treatment of chronic lateral elbow tendinopathy by a diathermy “T-Plus”. Common extensor tendon, radiohumeral capsule and superficial temperatures were registered after each application for the duration of the 30-minute treatment protocol. Results. During all applications, we observed a current flow over 0.03 A. The protocol showed a statistically significant increase in superficial temperature increased by 24% (5.02º) (p0.005), the common extensor tendon by 19.7% (4.36º) (p0.007), and the radiohumeral joint capsule by 17.5% (3.41º) (p0.005) at the end of the 30-minute protocol compared to the baseline temperature. Conclusion. The different applications of the protocol showed specific effects in the temperature and the current flow in the common extensor tendon and the radiohumeral capsule. All applications of the protocol produced a current flow which is associated with the generation of cell proliferation. These results strengthen the hypothesis of cell proliferation and thermal changes in deep and distal structures. More studies are needed to confirm these result
