BACKGROUND Calf muscle strain and Achilles tendon injuries are common in many sports. For the treatment of muscular and tendinous injuries, one of the newer approaches in sports medicine is capacitive-resistive electric transfer therapy. Our objective was to analyze this in vitro, using invasive temperature measurements in cadaveric specimens. METHODS A cross-sectional study designed with five fresh frozen cadavers (10 legs) were included in this study. Four interventions (capacitive and resistive modes; low- and high-power) was performed for 5 min each by a diathermy "T-Plus" device. Achilles tendon, musculotendinous junction and superficial temperatures were recorded at 1-min intervals and 5 min after treatment. RESULTS With the low-power capacitive protocol, at 5 min, there was a 25.21% increase in superficial temperature, a 17.50% increase in Achilles tendon temperature and an 11.27% increase in musculotendinous junction temperature, with a current flow of 0.039 A ± 0.02. With the low-power resistive protocol, there was a 1.14% increase in superficial temperature, a 28.13% increase in Achilles tendon temperature and an 11.67% increase in musculotendinous junction temperature at 5 min, with a current flow of 0.063 A ± 0.02. With the high-power capacitive protocol there was an 88.52% increase in superficial temperature, a 53.35% increase in Achilles tendon temperature and a 39.30% increase in musculotendinous junction temperature at 5 min, with a current flow of 0.095 A ± 0.03. With the high-power resistive protocol, there was a 21.34% increase in superficial temperature, a 109.70% increase in Achilles tendon temperature and an 81.49% increase in musculotendinous junction temperature at 5 min, with a current flow of 0.120 A ± 0.03. CONCLUSION The low-power protocols resulted in only a very slight thermal effect at the Achilles tendon and musculotendinous junction, but current flow was observed. The high-power protocols resulted in a greater temperature increase at the Achilles tendon and musculotendinous junction and a greater current flow than the low-power protocols. The high-power resistive protocol gave the greatest increase in Achilles tendon and musculotendinous junction temperature. Capacitive treatments (low- and high-power) achieved a greater increase in superficial temperature.

电容-电阻电转移在腓肠肌跟腱和肌腱末端交界处的热和非热效应：尸体研究。

背景技术小腿肌肉拉伤和跟腱损伤在许多运动中很常见。对于肌肉和肌腱损伤的治疗，运动医学中的一种新方法是电容电阻式电转移疗法。我们的目标是使用尸体标本中的有创温度测量在体外进行分析。方法这项横断面研究设计了五个新鲜的冷冻尸体（10条腿），纳入本研究。用透热疗法的“ T-Plus”装置进行5分钟的四种干预（电容和电阻模式；低功率和高功率）。治疗后每隔1分钟和5分钟记录一次跟腱，肌腱连接处和浅表温度。结果使用低功耗电容协议时，在5分钟时，表面温度增加了25.21％，即17。跟腱温度增加50％，肌腱末端温度增加11.27％，电流为0.039 A±0.02。使用低功率电阻方案时，在5分钟时表面温度增加1.14％，跟腱温度增加28.13％，肌腱末端温度增加11.67％，电流为0.063 A±0.02。使用大功率电容协议时，在5分钟内，表面温度增加88.52％，跟腱温度增加53.35％，肌腱末端温度增加39.30％，电流为0.095 A±0.03。使用大功率电阻方案时，表层温度增加21.34％，跟腱温度增加109.70％，而跟腱温度增加81.。5分钟时肌腱末端温度升高49％，电流为0.120 A±0.03。结论低功率方案仅在跟腱和肌腱末端交界处产生很小的热效应，但观察到电流。与低功率协议相比，高功率协议导致跟腱和肌腱连接处的温度升高更大，并且电流更大。高功率电阻方案使跟腱和肌肉末端连接处的温度增加最多。电容处理（低功率和高功率）使表面温度有了更大的提高。结论低功率方案仅在跟腱和肌腱末端交界处产生很小的热效应，但观察到电流。与低功率协议相比，高功率协议导致跟腱和肌腱连接处的温度升高更大，并且电流更大。高功率电阻方案使跟腱和肌肉末端连接处的温度增加最多。电容处理（低功率和高功率）使表面温度有了更大的提高。结论低功率方案仅在跟腱和肌腱末端交界处产生很小的热效应，但观察到电流。与低功率协议相比，高功率协议导致跟腱和肌腱连接处的温度升高更大，并且电流更大。高功率电阻方案使跟腱和肌肉末端连接处的温度增加最多。电容处理（低功率和高功率）使表面温度有了更大的提高。高功率电阻方案使跟腱和肌肉末端连接处的温度增加最多。电容处理（低功率和高功率）使表面温度有了更大的提高。高功率电阻方案使跟腱和肌肉末端连接处的温度增加最多。电容处理（低功率和高功率）使表面温度有了更大的提高。
