Is Tecar Therapy Effective on Biceps Femoris and Quadriceps Rehabilitation? A Cadaveric Study.

BACKGROUND: Capacitive-resistive electric transfer therapy is an interesting rehabilitation treatment to use in musculoskeletal injuries. The purpose is to analyze the temperature change and current flow in superficial and deep biceps femoris and quadriceps tissues when applying different protocols of capacitive-resistive electric transfer therapy. METHODS: Five cryopreserved cadavers (10 legs) were included in this study. Four interventions (high/low power) were performed for 5 minutes. Dynamic movements were performed to the biceps femoris and quadriceps. Superficial, middle, and deep temperature were recorded at 1-minute intervals and 5 minutes after the treatment using invasive temperature meters placed with ultrasound guidance. RESULTS: Low-power applications have generated a very low thermal effect and an important current flow. The high-power capacitive application achieves a greater increase in superficial temperature compared with low power (P < .001). The high-power resistive application recorded a greater increase in superficial, middle, and deep temperatures with a greater current flow compared with the other applications (P < .001). CONCLUSION: This study could serve as basic science data to justify the acceleration of the processes of muscle recovery, improving cell proliferation without increasing the temperature in acute muscle injuries and increasing the temperature and viscoelasticity of the tissues in chronic processes with this therapy.

Effects on Neuromuscular Function After Ischemic Compression in Latent Trigger Points in the Gastrocnemius Muscles: A Randomized Within-Participant Clinical Trial.

OBJECTIVE: The purpose of this study was to evaluate changes in neuromuscular function, pain perception, and basic physical properties in latent myofascial trigger points (TrPs) after a single treatment session of ischemic compression in the gastrocnemius muscle. METHODS: A randomized within-participant clinical trial with a blinded assessor was conducted. Twenty-nine asymptomatic volunteers with latent gastrocnemius-muscle TrPs were bilaterally explored. Each extremity was randomly assigned to the control group (no treatment) or the experimental group (90 seconds of ischemic compression over each TrP). Neuromuscular function of the gastrocnemius muscle was assessed using a MyotonPro. Muscle flexibility was analyzed using the lunge test and the passive ankle range of motion. The strength was determined with a handheld dynamometer (MicroFET2). Pain perception was analyzed with a 0-to-10 numerical pain rating scale and determination of pressure pain thresholds over each latent TrP. RESULTS: The results revealed a reduction of 15.8% in pain perception and an increment of pressure tolerance of 9.9% without pain in the treatment group. Changes in muscle flexibility (active and passive) and most parameters for neuromuscular response (rigidity, elasticity, and relaxation) were also observed, but they were not significantly different between groups. The clinical effect sizes were moderate for pain perception (d = 0.69), pressure pain threshold (d = 0.78), muscle tone (d = 0.51), and elasticity (d = 0.54) in favor of the treated extremity. Small clinical effect sizes were observed for muscle physical outcomes. CONCLUSION: The present study shows that the use of a single session of ischemic compression for latent gastrocnemius-muscle TrPs improved some sensory outcomes. The effects on ankle range of motion and neuromuscular responses were inconclusive.

The Effectiveness of Massage Therapy for Improving Sequelae in Post-Stroke Survivors. A Systematic Review and Meta-Analysis.

OBJECTIVE: To assess the effect of therapeutic massage for improving sequelae in stroke survivors. METHODS: A systematic review of the nine medical databases from January 1961 to December 2020 was carried out. The bibliography was screened to identify randomized controlled clinical trials (RCTs). Two reviewers independently screened references, selected relevant studies, extracted data and assessed the risk of bias using the PEDro scale. The primary outcome was upper and lower limb motor function and spasticity. RESULTS: A total of 3196 studies were identified and 18 RCT were finally included (1989 individuals). A meta-analysis of RCTs in the comparison of Chinese massage (Tuina) plus conventional physiotherapy versus conventional physiotherapy was performed. The mean difference (MD) in the subacute stage on upper limb motor-function using the Fugl Meyer Assessment was 2.75; (95% confidence interval (CI) from 0.97 to 4.53, p = 0.002, I2 = 36%). The MD on upper limb spasticity using modified Ashworth scale was -0.15; (95% CI from -0.24 to -0.06, p < 0.02, I2 = 0%).The MD on lower limb spasticity was -0.59; (95% CI from -0.78 to -0.40, p < 0.001, I2 = 0%) in the endpoint. CONCLUSIONS: Therapeutic massage, especially Tuina, in addition to conventional therapy is effective for improving motor function and for reducing spasticity in stroke survivors.

Effects of a Massage Protocol in Tensiomyographic and Myotonometric Proprieties.

BACKGROUND: Pre-competition massage is usually used to improve athletic performance and reduce risk of injury. Despite its usual use, the effects of pre-competition massage on neuromuscular function have barely been studied. The aim of this study is to evaluate the effects of the pre-competition massage over the gastrocnemius neuromuscular function. METHOD: The study is a quasi-experimental clinical trial thirty healthy athletes were enrolled in the study. Subjects received an intervention in one leg (experimental), consisting of a massage, and no intervention in the opposite leg (control). From all values of neuromuscular function, the following were analyzed: contraction time (Tc) and maximal displacement (Dm) by tensiomyography, and stiffness and tone by myotonometry. RESULTS: Main effects of pre-competition massage on neuromuscular function include a significant (p < 0.05) increase in Tc and Dm variables, as well as a reduction in stiffness and tone. CONCLUSION: Data shows an increase in Tc and maximal radial displacement (Dm) variables, as well as a reduction in stiffness and tone. More quality studies are needed to draw clear conclusions about the effects of pre-competition massage.

"Short- and mid-term effects of adding upper cervical manual therapy to a conventional physical therapy program in patients with chronic mechanical neck pain. Randomized controlled clinical trial."

OBJECTIVE: To evaluate the effect of adding an Upper Cervical Translatoric Mobilization (UCTM) or an Inhibitory Suboccipital Technique (IST) to a physiotherapy treatment in the symptomatology and function of mechanical chronic neck pain patients. DESIGN: Randomized controlled trial. SETTING: Primary Care Center in Cornellà, Spain. SUBJECTS: 78 patients (64 women), with mean age (SD) of 59.96 (13.30) years with mechanical chronic neck pain were divided in three groups: control, IST and UCTM groups. INTERVENTIONS: All groups received 15 physiotherapy sessions for three weeks. The UCTM and IST groups added 5 minutes of the assigned technique during six sessions. MAIN MEASURES: Neck disability index (NDI) and numeric pain rating scale (NPRS) for neck pain were measured baseline, three-weeks and 15-weeks follow-up. RESULTS: NDI (SD) at baseline, three-weeks and 15-weeks were 11.62 (7.08), 9.65 (6.25), 7.58 (5.64) for the control group, 14.38 (6.92), 8.50 (6.11), 7.12 (4.98) for the IST group and 13.19(7.23), 5.35(6.10), 4.35(2.76) for the UCTM group. NPRS (SD) at baseline, three-weeks and 15-weeks were 58.69 (19.46), 45.19 (23.43), 44.58 (24.08) for the control group; 64.08 (19.26), 42.19 (19.69), 34 (21.14) for the IST group; and 67.65 (20.65), 36.23 (20.10), 39.85 (25.44) for the UCTM group. CONCLUSIONS: Compared with no treatment, both forms of mobilization were associated with reduced disability at three weeks, and UCTM remained better than control at 15 weeks; there were no significant differences between the two mobilization groups. TRIAL REGISTRATION: This study was registered in Clinicaltrials.gov (NCT02832232).

Does Upper Cervical Manual Therapy Provide Additional Benefit in Disability and Mobility over a Physiotherapy Primary Care Program for Chronic Cervicalgia? A Randomized Controlled Trial.

Introduction: Neck pain is a condition with a high incidence in primary care. Patients with chronic neck pain often experience reduction in neck mobility. However, no study to date has investigated the effects of manual mobilization of the upper cervical spine in patients with chronic mechanical neck pain and restricted upper cervical rotation. Objective: To evaluate the effect of adding an upper cervical translatoric mobilization or an inhibitory suboccipital technique to a conventional physical therapy protocol in patients with chronic neck pain test on disability and cervical range of motion. Design: Randomized controlled trial. Methods: Seventy-eight patients with chronic neck pain and restricted upper cervical rotation were randomized in three groups: Upper cervical translatoric mobilization group, inhibitory suboccipital technique group, or control group. The neck disability index, active cervical mobility, and the flexion-rotation test were assessed at baseline (T0), after the treatment (T1), and at three-month follow-up (T2). Results: There were no statistically significant differences between groups in neck disability index. The upper cervical translatoric mobilization group showed a significant increase in the flexion-rotation test to the more restricted side at T1 (F = 5.992; p < 0.004) and T2 (F = 5.212; p < 0.007) compared to the control group. The inhibitory suboccipital technique group showed a significant increase in the flexion-rotation test to the less restricted side at T1 (F = 3.590; p < 0.027). All groups presented high percentages of negative flexion-rotation tests. (T1: 69.2% upper neck translator mobilization group; 38.5% suboccipital inhibition technique group, 19.2% control group; at T2: 80.8%; 46.2% and 26.9% respectively). No significant differences in the active cervical mobility were found between groups. Conclusion: Adding manual therapy to a conventional physical therapy protocol for the upper cervical spine increased the flexion-rotation test in the short- and mid-term in patients with chronic neck pain. No changes were found in the neck disability index and the global active cervical range of motion.

Effectiveness of Protein Supplementation Combined with Resistance Training on Muscle Strength and Physical Performance in Elderly: A Systematic Review and Meta-Analysis.

The aim of this study was to evaluate the effectiveness of the combination of resistance training (RT) and protein supplementation (PS), compared to RT alone or combined with a placebo (plS), in the improvement of muscle strength and physical performance. The search strategy in PubMed, Cochrane Library, and Web of Sciences databases found a total of 294 studies. Once inclusion and exclusion criteria were applied, 16 studies were included for the qualitative analysis. A total of 657 healthy elderly (>60 years) participants were analysed. Finally, 15 articles were included in the quantitative analysis with one being excluded due to issues with data availability. Upper-limb, lower-limb, and handgrip strength were the primary outcomes of the meta-analysis. The secondary outcomes, related to physical performance, were Short Physical Performance Battery (SPPB), gait speed, and the five-chair-rise test (5CRT). The main results of the meta-analysis show no statistical differences for upper-limb (SMD: 0.56, 95% CI: -0.09, 1.21, p = 0.09, I2 = 68%), lower-limb (SMD: 0.00, 95% CI: -0.18, 0.18, p = 1.0, I2 = 11%), and handgrip strength (SMD: 0.03, 95% CI: -0.26, 0.32, p = 0.84, I2 = 0%) between the RT + PS and the RT alone (or combined with plS). Moreover, no statistical differences were found relating to physical performance. In view of these results, protein supplementation combined with RT does not provide additional benefits compared to RT alone or with plS in healthy elderly adults.

Thermal and non-thermal effects off capacitive-resistive electric transfer application on the Achilles tendon and musculotendinous junction of the gastrocnemius muscle: a cadaveric study.

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.

Effectiveness of diacutaneous fibrolysis for the treatment of chronic lateral epicondylalgia: a randomized clinical trial.

OBJECTIVE: To assess the end of treatment and three months after treatment effects of diacutaneous fibrolysis as adjuvant of physical therapy for chronic lateral epicondylalgia. DESIGN: Double-blind (patient and evaluator) randomized controlled trial. SETTING: Primary Care Center of the Spanish NHS. SUBJECTS: A total of 54 people with 60 elbows affected with chronic lateral epicondylalgia, 33 women, mean (SD) age was 48.43 (8.69) years. INTERVENTIONS: All three groups (Intervention, Placebo and Control) received three weeks of physical therapy treatment and in addition Intervention Group received six sessions of real diacutaneous fibrolysis and Placebo Group received six sessions of sham diacutaneous fibrolysis. MAIN MEASURES: Pain intensity, pressure pain threshold, pain free grip strength, function and subjective assessment were assessed at baseline, at the end of treatment and three months after treatment. RESULTS: Between-group results at three months after treatment showed a statistically significant improvement of the Intervention Group in pain free grip strength (mean, 7.91 km/cm2; SD, 9.23) compared to the Placebo Group (mean, 1.47 km/cm2; SD, 7.86) and to the Control Group (mean, 2.09 km/cm2; SD, 4.45) ( P values <0.01 and <0.03, respectively) and also in function (mean, 20.87; SD, 14.25) compared to the Control Group (mean, 4.17; SD, 18.02) ( P < 0.01). Subjective assessment was statistically better in the Intervention Group both at the end of treatment ( P < 0.01) and three months after treatment ( P < 0.03). CONCLUSION: Diacutaneous fibrolysis added to physical therapy provides better results in the treatment of chronic lateral epicondylalgia, with greater clinical satisfaction among patients.
