Effects of transcutaneous radiofrequency diathermy versus ultrasound on latent myofascial trigger points in the upper trapezius: A randomized crossover trial
Currently, the use of radiofrequency diathermy for the treatment of neck pain is booming.
OBJECTIVE:
This study aimed to evaluate the clinical efficacy of Digital Capacitive Diathermy (DCD®) on stiffness, pain, cervical range of motion, and cervical disability and to compare it with ultrasound (US) in patients with latent myofascial trigger point (MTrP) in the upper trapezius.
METHODS:
Nineteen participants with latent MTrPs in the upper trapezius were included in the assessor-masked, randomized, clinical crossover trial. Subjects were exposed to both interventions: US and DCD® and treatment effectiveness was measured by myotonometric variables, pressure pain threshold (PPT), visual analog scale (VAS), cervical side-bending flexion ranges, and the neck disability index scale (NDI).
RESULTS:
There were no significant differences between US and DCD® interventions regarding changes in outcome measures. The US group achieved a statistically significant difference of 2.16 to 1.13 points ( 0.005; 0.646) for the VAS. The DCD® intervention showed a statistically significant improvement of 1.11 points for the NDI at 1-week following intervention (95% CI 0.14–2.07; 0.27; 0.217).
CONCLUSION:
Our findings suggest that DCD® and US can both be considered effective modalities for the treatment of latent MTrPs, having a longer duration of action with DCD® therapy.
