“…Second, it is unknown whether the same effect of CRET would be found in the other areas. Navarro-Ledesma et al described that CRET intervention could change the elasticity of the supraspinatus tendon in healthy badminton athletes [44]. The insertion site of the supraspinatus tendon has insu cient blood supply and tissue degeneration or rupture may likely [45]; therefore, CRET therapy may be effective.…”

Background: Capacitive and resistive electric transfer (CRET) is becoming popular in sports settings. Although CRET is effective for improving pain and healing injured tissues, its influence on muscle function and morphology is still unclear. This study confirmed the immediate effects of CRET on the duration of muscular stiffness and the range of motion (ROM). Methods: This paper describes the protocol for a single arm trial with non-blinding of participants and researcher. Twenty-four healthy men participated in the study. They received CRET therapy for their lower back areas. The muscular stiffness of the multifidus muscle (superficial and deep) and the ROM using the active straight leg raise (ASLR) test were measured pre-intervention, post-intervention (immediately), and 15 minutes and 30 minutes post-intervention. We compared these parameters with one-way analysis of variance and Dunnett’s test (multiple comparison tests for subtests). Results: The muscular stiffness of the superficial and deep multifidus muscles became significantly lesser, and the ASLR test showed a significant increase compared to that obtained at pre-intervention. In addition, these effects persisted for 30 minutes. Conclusions: Warm-up is vital for improving muscular stiffness and for increasing the ROM. CRET is a useful device to achieve these aims as a passive warm-up method in sports settings.Trial registration number: UMIN000046304.

“… 8 Methodology used in previous studies will be followed. 32 All measurements will be performed with the Logiq S7 using a 15-MHz linear probe (GE Healthcare, Milwaukee, WI) by a physiotherapist expert in musculoskeletal ultrasound imaging with 10 years of experience in ultrasound imaging. The strain elastography (SEL) will be obtained in the same position that the PPT assessment was carried out.…”

“…Sample size for this trial is based on an expected mean difference between groups of 2 points of the NPRS, which is the minimum clinically important difference. 38 Based on results of other randomised clinical trials 32 , 39 and previous reviews, 40 assuming the standard deviation of the NPRS of 2.0 units to detect this difference between the intervention and placebo groups, with a value of α = 0.05 and a statistical power of 90%, a minimum of 22 patients per group is needed.…”

Background: The development of an integral and global treatment to improve the quality of life in those with fibromyalgia syndrome (FMS) is challenging. The aim of this study is to investigate the impact of whole-body photobiomodulation (PBM) on pain perception, functionality, quality of soft tissue, central sensitisation and psychological factors in patients suffering with FMS. Methods: This study is a randomised, placebo-controlled clinical trial. A total of 44 participants will be recruited in a private care practice and randomised to receive either a whole-body PBM therapy programme or placebo in the same care centre. The parameters of the PBM programme are as follows: wavelengths of red and near-infrared LEDs 50:50 ratio with 660–850 nanometers; fluence of 25.2 J/cm2; treatment time of 1200 s and a total power emitted of 967 W. Treatment sessions will be 3 times weekly for a period of 4 weeks, totalling 12 treatment sessions. Primary outcome will be pain (Numeric Pain Rating Scale; Widespread Pain Index; Symptom Severity Score). Secondary outcomes will be functionality (Fibromyalgia Impact Questionnaire; the Leisure Time Physical Activity Instrument), quality of soft tissue (elastography), central sensitisation (pain pressure threshold and the Autonomic Symptom Profile) and psychological factors (Pain Catastrophising scale, Tampa Scale, Self-Efficacy questionnaire). Assessments will be at baseline (T1), after session 6 (T2), after treatment (T3) and 2 weeks (T4), 3 (T5) and 6 (T6) month follow-up. Discussion: PBM therapy has been shown to reduce pain and inflammation and to increase the rate of tissue repair for a wide range of conditions, but its potential use as a whole-body treatment in FM is yet to be explored. This trial will investigate whether whole-body PBM therapy is effective at reducing pain intensity, improving functionality, quality of soft tissue, central sensitisation symptoms and psychological measurements. Furthermore, 3- and 6-month follow-up will investigate long-term efficacy of this treatment. Trial registration: NCT04248972.

“…Capacitive resistive monopolar radiofrequency (CRMR) has been widely used to treat different musculoskeletal disorders, such as osteoarthritis of the knee [ 1 ], cervico-brachial pain [ 2 ] and low back pain [ 3 ]. Furthermore, a CRMR application has shown other effects, such as a greater effect on haemoglobin saturation [ 4 ], immunological responses [ 5 , 6 ] and changes in tendon elasticity but only in the short term [ 7 ]. In this regard, hyperthermia techniques appear to be promising as a way to increase vascularity; blood perfusion; temperature; and therefore, the viscoelasticity of the soft tissue, which is thought to be crucial in keeping the musculoskeletal system healthy and functional [ 7 , 8 , 9 ].…”

The aim of this study is to analyse the changes that occur in the elasticity of the supraspinatus tendon after the application of a 448 kHz capacitive resistive monopolar radiofrequency (CRMR) at 3, 6 and 9 months in professional badminton players. A randomized double-blinded clinical trial that included 9 months of follow-up was used. A private care practice was used to recruit the participants of this study. They were randomly assigned either the CRMR treatment (n = 19) or the placebo treatment (n = 19). The experimental group received a total of nine treatments of 448 kHz CRMR divided into three treatments per week. The control group received the same regimen but with no radiofrequency. Quantitative ultrasound strain elastography was used to report the main values for three areas of the supraspinatus tendon. These were measured at the start (T1) and directly after (T2), one week after, (T3), three months after (T4), six months after (T5) and nine months after (T6) the completion of the intervention program. There were statistically significant differences in the supraspinatus tendon elasticity immediately after (p ≤ 0.001), one week after (p ≤ 0.001) and three months after (p = 0.01) the intervention program. No significant changes were found six or nine months after the intervention program. A three-week intervention program using 448 kHz produced significant changes in the elasticity of the supraspinatus tendon, with the changes lasting up to approximately three months when compared to the control group.
