Background: Transcutaneous electrical nerve stimulation(TENS) is an effective physiological intervention for people with stroke which aims at reducing muscle spasticity, enhancing muscle strength, and improving motor control and function. In view of the potentials to enhance greater cortical activation of the lesion side by eliciting spare neural pathways through bilateral intervention, this study examined whether the combined use of bilateral TENS (Bi-TENS) and task-oriented training (TOT) was superior to unilateral TENS(Uni-TENS)+TOT, placebo-TENS+TOT and no active treatment to improve the motor impairment of upper limb function in people with stroke. Method: There were 120 subjects with stroke(44 females, mean age=61.52±6.73 years, post-stroke duration=6.04±3.12years) being randomly allocated into 4 groups, including the Bi-group (n=30), Uni-group (n=30), placebo group (n=30) and control group (n=30). Subjects in the Bi-group, Uni-group and placebo group got 60 minutes TENS and TOT simultaneously per time for 20 times(3 times per week for 7 weeks). In the Bi-group, TENS stimulated the radial and median nerves of the bilateral upper limbs. In the Uni-group, TENS and placebo-TENS stimulated the affected and unaffected side, respectively. In the placebo group, placebo-TENS were placed on bilateral sides. In the control group, subjects did not receive any active treatment. Level of motor impairment was assessed by the Fugl-Meyer Assessment of Upper Extremity (FMA-UE). Result: The Bi-group had a significant greater improvement in FMA-UE than the Uni-group(mean change=2.02, p=0.005), placebo group (mean change=2.49, p=0.001) and control group(mean change=3.08, p<0.001) at post-intervention. The Bi-group(mean change=3.25, p<0.001) and Uni-group(mean change=1.23, p=0.015) showed a significant within-group improvement in FMA-UE since 10 sessions of treatment. No significant change was found in the placebo and control groups. Conclusion: Bi-TENS is superior to Uni-TENS, placebo-TENS and no active treatment in augmenting the recovery of upper limb motor impairment in people with chronic stroke.

Background. Parasternal block and transcutaneous electrical nerve stimulation (TENS) have been demonstrated to produce effective analgesia and reduce postoperative opioid requirements in patients undergoing cardiac surgery.Objectives. To compare the effectiveness of TENS and parasternal block on early postoperative pain after cardiac surgery.Methods. One hundred twenty patients undergoing cardiac surgery were enrolled in the present randomized, controlled prospective study. Patients were assigned to three treatment groups: parasternal block, intermittent TENS application, or a control group.Results. Pain scores recorded 4 h, 5 h, 6 h, 7 h, and 8 h postoperatively were lower in the parasternal block group than in the TENS and control groups. Total morphine consumption was also lower in the parasternal block group than in the TENS and control groups. It was also significantly lower in the TENS group than in the control group. There were no statistical differences among the groups regarding the extubation time, rescue analgesic medication, length of intensive care unit stay, or length of hospital stay.Conclusions. Parasternal block was more effective than TENS in the management of early postoperative pain and the reduction of opioid requirements in patients who underwent cardiac surgery through median sternotomy.

Electrical Nerve Stimulation

Background: Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive pain therapy that uses the sensory effects of an electrical current applied to the skin. Some clinical studies demonstrated that this treatment helps to reduce acute and chronic pains, while others gave sometimes contradictory or uncertain conclusions about the performances of this strategy according to pathology classification. The purpose of this study is the development and evaluation of a new modulated version of transcutaneous electrical nerve stimulation called PWM-TENS. The principle is based on an automatic variation of the stimulation parameters (frequency, amplitude, duration, shape, cyclic ratio) according to the pain evolution. Methods: The study was a controlled clinical trial involving 15 participants, divided into 2 groups. The first experimental group performed modulated PWM-TENS electro-stimulation sessions applied to the painful areas 3 to 4 times a day, for one month. The second control group did parallel treatments by Placebo. The evaluation of the pain intensity is done with the Visual Analog Scale (EVA), the DN4 and SF36 questionnaires. Results: The tests and measurements with our embedded PWM-TENS technique demonstrated that we succeeded to increase the analgesic effect after stopping the stimulation and reduced the pain sensation by about 60%. An improvement in pain intensity scores and questionnaires (EVA, DN4), as well as the quality of life score (SF36), was observed. Also, a reduction of the treatment period from 3 to 1 month was also obtained. Conclusion: The first results clinically observed in the PWM-TENS technique are encouraging. The findings of this study confirm that this noninvasive strategy is suitable and useful for acute pains coming from the nociceptive, neuropathic and musculoskeletal origin. However, its efficiency is moderated and less adapted for low back pain. The experiments make it possible to estimate whether this modulated TENS method could improve existing anti-pain therapies, taking into account objective and subjective evaluation criteria. But this study must be followed by large population samples to answer all the problems of acute and chronic pains.

Background: Restless legs syndrome also known as Willis-Ekbom disease is a sensor motor disorder composed of an urge to move with or without associated discomfort that occurs with inactivity and improves with movement. The symptoms occur in leg muscles like calves and thighs. The feet and arms also affected and it causes the functional disability in pregnant women. Sleep disorder is typically the biggest complication of this condition. Unpleasant sensations are deep in the legs. Sensations appear during periods of rest or inactivity particularly in the evening and at night and relived by movement. Prevalence of RLS among pregnant women ranged from 10 to 34%. Aim: The aim of the study is to prove the effect of Transcutaneous Electrical Nerve Stimulation (TENS) with Stretching and Exercises in restless leg syndrome among pregnant women. Objectives: To determine and prove the effectiveness of TENS with stretching to relive pain and improve the functional ability in restless leg syndrome among pregnant women. Materials and Methods: A Quasi-experimental study was conducted on 30 subjects using convenient sampling technique based on inclusion and exclusion criteria. Subjects were allotted into 2 groups i.e., Group A with 15 subjects and Group B with 15 subjects using odd even method of sampling. Experimental group will be treated with TENS and Stretching. Control group will be treated with exercises and massage. Result: Statistical Analysis of Post test for pain and functional performance revealed that patients who received Transcutaneous Electrical Nerve Stimulation (TENS) with Stretching in Group A showed marked improvement compared to patients who received Massage and Exercises in Group B. Conclusion: From the result of the study it concluded that Transcutaneous Electrical Nerve Stimulation (TENS) with Stretching is more effective than massage and exercises in subjects with restless leg syndrome among pregnant women.

This study examined the clinical effectiveness of high-frequency transcutaneous electrical nerve stimulation for reducing hypersensitivity of the hand. Nineteen patients suffering from hand hypersensitivity were randomly assigned into either a treatment or a placebo group. A visual analogue scale and the Downey Hand Centre Hand Sensitivity Test were used to measure the tactile tolerance of the hand. Grip strength was assessed by a grip dynamometer. Daily applications of electrical stimulation were provided for 2 weeks. Significantly lower pain scores were found in the treatment group than in the placebo group by Day 7 and Day 11. The ranking of ten dowel textures of the Downey Hand Centre Hand Sensitivity Test in the treatment group was significantly higher than in the placebo group by Day 7 and Day 11. However, no significant intergroup difference was found in grip strength.

The aim of this study was to determine the role of transcutaneous electrical nerve stimulation (TENS) in the viability of random skin flaps. In 30 Wistar-EPM rats, a random 10×4 cm skin flap was raised and a plastic barrier was interposed between the flap and its bed. Immediately after surgery and for two subsequent days, the rats in group 1 (the control group) were anesthetized for 1 h with the electrodes positioned in the base of the flap and without the administration of the electric stimulus. The rats in group 2 (the treatment group) were submitted to TENS for 1 h immediately after the surgery and for two subsequent days. The percentage of necrotic area (averages of 43.11% in the rats in group 1 and 23.52% in the rats in group 2) was calculated on the seventh postoperative day in both groups. Statistical analysis proved that TENS was more efficient in increasing random skin flap viability than was the method used in the control group.

Flap Survival

The effects of electroacupuncture (EA) and transcutaneous electrical nerve stimulation (TENS) were investigated in the musculocutaneous flap in a rat model by measuring the surviving area and blood flow in the flap. Rats were divided into the control group, and groups treated with EA and TENS. Experimental results of this study show that flap survival area did not increase by EA but increased significantly by TENS treatment, and that blood flow in the periphery was significantly larger than that at the base.

Background. A patient- and assessor-blinded randomized controlled trial was conducted to examine the effectiveness of auricular transcutaneous electrical nerve stimulation (TENS) in relieving posthysterectomy pain.Method. Forty-eight women who had undergone a total abdominal hysterectomy were randomly assigned into three groups (n=16each) to receive either (i) auricular TENS to therapeutic points (the true TENS group), (ii) auricular TENS to inappropriate points (the sham TENS group), or (iii) 20 minutes of bed rest with no stimulation (the control group). The intervention was delivered about 24 hours after the operation. A visual analogue scale was used to assess pain while resting (VAS-rest) and upon huffing (VAS-huff) and coughing (VAS-cough), and the peak expiratory flow rate (PEFR) was assessed before and at 0, 15, and 30 minutes after the intervention.Result. As compared to the baseline, only the true TENS group reported a significant reduction in VAS-rest (P=.001), VAS-huff (P=.004), and VAS-cough (P=.001), while no significant reduction in any of the VAS scores was seen in the sham TENS group (allP>.05). In contrast, a small rising trend was observed in the VAS-rest and VAS-huff scores of the control group, while the VAS-cough score remained largely unchanged during the period of the study. A between-group comparison revealed that all three VAS scores of the true TENS group were significantly lower than those of the control group at 15 and 30 minutes after the intervention (allP<.02). No significant between-group difference was observed in PEFR at any point in time.Conclusion. A single session of auricular TENS applied at specific therapeutic points significantly reduced resting (VAS-rest) and movement-evoked pain (VAS-huff, VAS-cough), and the effects lasted for at least 30 minutes after the stimulation. The analgesic effects of auricular TENS appeared to be point specific and could not be attributed to the placebo effect alone. However, auricular TENS did not produce any significant improvement in the performance of PEFR.
