Abstract

Objective

To study changes in supraspinatus tendon elasticity after a 448 kHz capacitive resistive monopolar radiofrequency (CRMR) intervention in professional badminton players.

Design

Double-blinded randomized clinical trial.

Setting

All participants were recruited in a private care practice. Participants were randomized to receive either a CRMR treatment (n = 19) or placebo (n = 19).

Subjects

Professional badminton players (n = 38).

Intervention

A total of nine intervention (three per week) with CRMR at 448 kHz were carried out in the experimental group. The same intervention without an active CRMR current was carried out in the control group.

Main measures

Mean values of three different regions of the supraspinatus tendon were reported at baseline (T1), immediately after the intervention (T2) and one week after the end of the whole intervention program (T3) using quantitative ultrasound strain elastography (SEL).

Results

There were statistically significant differences in the supraspinatus tendon elasticity immediately after the intervention (p= <.001) and one week after the end of the whole intervention program (p=.001).

Conclusion

CRMR at 448 kHz produces significant changes in supraspinatus tendon elasticity after an intervention program of three weeks and those changes last for a week when compared to control group. Clinical trial registration: NCT04273633 (ClinicalTrials.gov).

定量超声弹性成像技术在专业羽毛球运动员中测量448 kHz射频刺激对脊柱上肌腱弹性的短期影响：一项双盲随机临床试验

摘要

客观的

研究在专业羽毛球运动员中进行448 kHz电容性电阻性单极射频（CRMR）干预后的棘上肌腱弹性的变化。

设计

双盲随机临床试验。

环境

所有参与者都是在私人护理实践中招募的。参与者被随机分配接受CRMR治疗（n  = 19）或安慰剂（n  = 19）。

科目

专业羽毛球运动员（n  = 38）。

干涉

实验组总共进行了448 kHz的CRMR干预9次（每周3次）。在对照组中，在没有激活的CRMR电流的情况下进行了相同的干预。

主要措施

在基线（T1），干预后（T2）和整个干预程序结束（T3）结束后一周，使用定量超声应变弹性成像（SEL）在基线（T1）上报告了棘上肌腱三个不同区域的平均值。

结果

有统计学在冈上肌腱弹性显著差异干预（后立即p = <0.001）和整个介入程序（的端部后一周p = 0.001）。

结论

经过三周的干预后，在448 kHz的CRMR产生了棘上肌腱弹性的显着变化，与对照组相比，这些变化持续了一周。临床试验注册： NCT04273633（ClinicalTrials.gov）。
