Symptoms And Signs

Introduction. Patients with craniomandibular disorders suffer from hypertonic, fatigued and painful masticatory muscles. This condition can lead to limitation of mandibular jaw movements. All of these symptoms and signs are included in myofascial pain dysfunction syndrome. Transcutaneous electrical nerve stimulation (TENS) has been used for treatment of these patients. Objective. The aim of this study was to assess the effect of TENS therapy on chronic pain reduction in patients with the muscular dysfunction symptom. Methods. In order to evaluate the effect of TENS therapy before and after the treatment, Craniomandibular Index (Helkimo) was used. Pain intensity was measured by VAS. Patients had TENS treatment over two-week period. BURST TENS modality was used. Current intensity was individually adjusted. Results. Two patients did not respond to TENS therapy. Complete pain reduction was recorded in 8 patients, while pain reduction was not significantly different after TENS therapy in 10 patients. Conclusion. TENS therapy was confirmed as therapeutic procedure in orofacial muscle relaxation and pain reduction.

The aim of this study was to examine the effects of transcutaneous electrical nerve stimulation on spasticity in patients with multiple sclerosis. The study was carried out in the Hacettepe University School of Physical Therapy and Rehabilitation. The subjects in the study were 10 clinically definite, primary and secondary progressive type multiple sclerosis outpatients with mild to moderate spasticity in the plantar flexor muscles of the ankle. Stimuli of frequency 100 Hz and pulse width 0.3 msec were used 20 minutes per day for 4 weeks. Patients were assessed by electromyography, Modified Ashworth Scale, and Ambulation Index. Electromyography was performed before and after the daily treatment of spastic muscles with transcutaneous electrical nerve stimulation in order to assess the effect on muscle relaxation. The Modified Ashworth Scale and Ambulation Index were used before and after 4 weeks' treatment. After 4 weeks of treatment, there were statistically significant reductions in spasticity of both extremities as assessed by myoelectric activity and the Modified Ashworth Scale (P < 0.05). Ambulation Index level was not improved significantly)P > 0.05).

Objectives: Myofascial pain dysfunction syndrome (MPDS) is the most common form of temporomandibular disorders. Because of the multifactorial nature of the problem, its management usually involves several treatment modalities to maximize their synergistic effects. This randomized clinical trial aimed to assess the efficacy of low-level laser therapy (LLLT) and transcutaneous electrical nerve stimulation (TENS) as an adjunct to pharmaceutical therapy for treatment of MPDS. Materials and Methods: This clinical trial evaluated 108 MPDS patients. First, the initial pain intensity of patients was determined using a visual analogue scale (VAS). The first phase of the study included education, awareness, self-care, behavior and relaxation therapy. After 1 month, the pain score was measured again using VAS. Patients who acquired a pain score >1 were divided into three groups of LLLT with diode (GAAlAr) laser with 0.2 W power, TENS, and control, using block randomization. All groups received 10 mg fluoxetine once daily, 0.25 mg clonazepam once daily and 10 mg baclofen three times a day. ANOVA was used to compare the recovery rate of the three groups. Results: Pain in the trapezius muscle and pain on mouth opening resolved faster in the laser + medication group. The recovery rate was faster in the mean muscle pain, general pain reported by patients, pain in the masseter and pterygoid muscles and pain and limitation in lateral movements in both laser + medication and TENS groups. Conclusion: Combination of LLLT and TENS with medication accelerated pain relief and resolved movement restrictions in MPDS patients. (IRCT registration number: IRCT201411113144N4)

Background: The delivery pain is an unpleasant experience which may generate some insecurity for the woman. Thus, some methods of analgesia need to be studied in order to generate greater comfort for the woman during labor. Objective: to evaluate the effect of transcutaneous electrical nerve stimulation (TENS) and cryotherapy (CRYO) on labor pain. Method/Design: quasi experimental study, randomized sample in two groups: TENS and CRYO. Pregnant women were selected in the Carmela Dutra Maternity (Florianópolis (SC), Brazil) according to inclusion criteria: women which are pregnant for the first time, age (18-40 years) and initial cervical dilatation of 4-5cm. The Visual Analogue Scale (VAS) was used to evaluate pain before and after each intervention. Results: 24 parturient women were studied (TENS = 11, CRYO = 13). In the TENS group, there was a significant result in pain relief after the first application (p = 0.002). VAS was reduced from 8 to 5.5, but not significant. In the CRYO group there was reduction of pain during the first application (p = 0.008), and in the second there was an increase in pain (p = 0.008). There was a significant difference between the techniques in the evaluation performed before the second application, with a lower value attributed to the CRYO group (p = 0.034). Conclusions: CRYO and TENS were effective in relieving pain during the first phase of the initial phase of labor. However, during the treatment, in the parturient women studied, there was maintenance of pain response by the CRYO group and decrease in the TENS group without reduction significant.

Electrical Nerve Stimulation

Temporomandibular disorders (TMD) are characterized by several signs and symptoms, such as pain and changes in the electrical activity of masticatory muscles. Considering that transcutaneous electrical nerve stimulation (TENS) is a resource indicated to promote analgesia, the objective of this study was to evaluate the effect of TENS on pain and electromyographic (EMG) activity of the jaw elevator muscles in TMD patients. This study evaluated 35 female volunteers: 19 TMD patients (mean age = 23.04 ± 3.5) and 16 normal subjects (mean age = 23.3 ± 3.0). Transcutaneous electrical nerve stimulation (conventional mode, 150 Hz) was applied once to each group for 45 minutes. Surface electromyography (gain of 100 times and 1 kHz sampling frequency) and the visual analogue scale (VAS) were applied before and immediately after TENS application. Both VAS data and root mean square (RMS) values were analyzed using Student's t-test. The TMD group, compared to the control group, showed higher EMG activity of the jaw elevator muscles at rest. No difference was observed between the groups regarding maximum voluntary clenching (MVC). In TMD patients, TENS reduced both pain and EMG activity of the anterior portion of the temporal muscle, increasing the activity of the masseter muscles during MVC. It is possible to conclude that a single TENS application is effective in pain reduction. However, it does not act homogeneously on the features of the electric activity of the muscles evaluated.
