Functional Electrical Stimulation is the clinical application of a small electric current to the intact nerves of the body, in order to trigger a muscle contraction. This contraction is then incorporated into a functional activity, for example walling. A clear distinction needs to be made between therapeutic stimulation and functional stimulation. The former being of an exercise orientation, where one would relax while the stimulation works on its own. Functional electrical stimulation on the other hand, incorporates this elicited muscle movement into an everyday activity, like standing, walking, reaching out etc. But recently, New method used to FES which updated electrode insult in muscle and small nerve branch. A lot of new research build up many countries such as England, USA, Japan, Spain, Canada. So I had been write this paper for introduce new FES method, and I hope to more enhanced motivation of therapist for the functional electric stimulation.

Purpose: This study was to examine the effects of electric stimulation therapy on chronic knee pain, exercise self-efficacy, and quality of life in Korean elderly women. Methods: The design was an unequivalent control pretest-posttest study. Samples were total of 60 (experimental: 30, control: 30) elderly women with healthy cognitive and communication abilities aged 65 years old and above. The experimental treatment involved was the electric stimulation of both thigh quadriceps muscles for 15 minutes per treatment, 3times per a week, for a total of 12 weeks. Measurements taken were S-F MPQ and AIMS for chronic knee pain, exercise self-efficacy measurement for exercise self-efficacy, and S-F 36 scale for quality of life. Data were analyzed using SPSS PC+ 12. Results: Chronic knee pain according to the Short-Form McGill Pain Questionnaire (t=43.563, p=.000) and Arthritis Impact Measurement Scale (t=31.364, p=.000) were significantly decreased in the experimental group by the application of electrical stimulation therapy. Exercise self-efficacy (t=107.116, p=.000) and quality of life (t=76.429, p=.000) were significantly increased in the experimental group by the application of electrical stimulation therapy. Conclusion: Electrical stimulation therapy could be a more effective primary nursing intervention in decreasing chronic knee pain, and on increasing exercise self-efficacy and quality of life for Korean elderly women.

Objective: This study aims to compare the range of motion of the joints by applying the contraction and relaxation techniques used in manual therapy as electrical stimulation treatment. Based on this, we would like to propose the possibility of using motor nerve electrical stimulation therapy for musculoskeletal physical therapy. Design: Single-arm interventional study Methods: Active and passive straight leg raising tests were performed on 20 healthy men and women in their 20s to measure the angle of hip joint flexion. Then, the electrical stimulation time was set to 10 seconds and 5 seconds of rest, and motor nerve electrical stimulation of 1 Hz was applied with the maximum strength that could withstand the hamstring muscles for 10 minutes. After electrical stimulation, straight leg raising tests again to confirm the range of motion of the hip joint flexion. Results: As a result of this study, it was confirmed that the joint range of motion was significantly improved for both active and passive straight leg raising tests after application of motor nerve electrical stimulation(p<.05). Conclusions: With a strong electrical stimulation treatment of 1 Hz, the effect similar to the contraction and relaxation technique used in manual therapy was confirmed through the joint range of motion. In the future, motor nerve electrical stimulation therapy can be used for musculoskeletal physical therapy to provide a new approach for patients with reduced pain and joint range of motion due to muscle tension.

In this paper, personal electrical stimulation medcial devices using bioelectrical stimulating was developed. Therapy effect of RET(resistive electric transfer) was more effective than CET(capacitive electric transfer), but CET was adopted because of safety issue. Then, the optimum parameters that may be effective in thin skin or facial wrinkles was set. For example, the frequency of the pulse voltage for stimulation is 1.8[MHz], burst frequency is 7[kHz] or 400[Hz], the development of devices was to have ON/OFF control and frequency control. When burst frequency was adjusted 7[kHz], heat was generated in the electrode. The case of 400[Hz] the heat was little generated. The microcontroller ATmega128-based experimental results show that the proposed personal high frequency electrical stimulation devices can be applied to medical equipment using therapy effect successfully.

The purpose of this study was to determine the effects of electric stimulation of abdominal region on the body composition and blood components in obesity. Control group measured pre and post test, and Experimental group I didn't receive electric stimulation in same environment as experimental group II. Experimental group II received electric stimulation on abdominal region. The result, experimental group II showed significant difference in weight, SLM, FFM, waist circumference, WHR, BMI, T-G, HDL-C. And experimental group I showed significant difference in waist circumference, WHR, T-C, and control group didn't show significant difference any variables. Therefore, electric stimulation effects on body composition in obesity persons.

Purpose: Rehabilitative devices are used to enhance sensorimotor training protocols, for improvement of motor function in the hemiplegic limb of patients who have suffered a stroke. Sensorimotor integration feedback systems, included with these devices, are very good therapeutic frameworks. We applied this approach using electrical stimulation in stroke patients and examined whether a functional electric stimulation-assisted biofeedback therapy system could improve function of the upper extremity in chronic hemiplegia. Methods: A prototype biofeedback system was used by six subjects to perform a set of tasks with their affected upper extremity during a 30-minute session for 20 consecutive working days. When needed for a grasping or releasing movement of objects, the functional electrical stimulation (FES) stimulated the wrist and finger flexor or extensor and assisted the patients in grasping or releasing the objects. Kinematic data provided by the biofeedback system were acquired. In addition, clinical performance scales and activity of daily living skills were evaluated before and after application of a prototype biofeedback system. Results: Our findings revealed statistically significant gradual improvement in patients with stroke, in terms of kinematic and clinical performance during the treatment sessions, in terms of manual function test and the Purdue pegboard. However, no significant difference of the motor activity log was found. Conclusion: Hemiplegic upper extremity function of a small group of patients with chronic hemiparesis was improved through two weeks of training using the FES-assisted biofeedback system. Further research into the use of biofeedback systems for long-term clinical improvement will be needed.

Evoked potentials(EP) are defined as electric responses of the nerves system to sensory stimulation. EPs are used mainly to test conduction in the visual, auditory, and somatosensory systems, especially in the central parts of these systems. Somatosensory evoked potentials (SEP) are the potentials elicited by stimulation of peripheral nerves and recorded at various sites along the sensory pathway. SEPs types consist mainly of SEPs to electric stimulation of arm or leg nerves. SEPs to arm stimulation are usually recorded simultaneously from clavicular, cervical, and scalp electrodes; SEPs to leg stimulation are recorded from lumbar, low thoracic, and scalp electrodes. Subject variables that have practical impotance are age, limb length, body height, and temperature. General clinical interpretation of abnormal SEPs wave decreases of peripheral conduction time, and abolition of SEPs recorded from different levels to identify lesions of peripheral nerves, plexus, nerve root, spinal cord, cauda equina, hemispheric brainstem, and cerebral parts of the somatosensory pathway.

A 19-year-old male patient presented with facial hemi-atrophy with unilateral spasms of the masseter and temporalis muscles. Ultrasound therapy and Transcutaneous Electric Nerve Stimulation therapy, known as combination therapy, were given on alternate days for 2 weeks. At the end of 2 weeks of combination therapy the patient reported a drastic reduction in the number of episodes of muscle spasm. The visual analog scale score for tenderness of the masseter and temporalis was also markedly reduced. No one has previously used combination therapy for the treatment of facial hemi-atrophy with hemi-facial spasms. The encouraging results of the combination therapy has prompted us to document this study.

Purpose: This study examined the effects of changes in the intensity of Functional Electrical Stimulation (FES) on CorticoMuscular Coherence (CMC) during action observation. This paper presents a neurophysiological basis for the effective intensity of FES. Methods: Twenty-seven healthy volunteers were asked to observed a video with FES. The FES was provided with a sensory stimulation level, nerve stimulation level, and motor stimulation level. Simultaneously, an electroencephalogram (EEG) of the sensorimotor cortex and electromyogram (EMG) from the wrist extensor muscle were recorded. The peak CMC and average CMC were analyzed to compare the differences caused by the FES intensity. Results: The peak CMC showed a significant increase in the alpha band during motor stimulation (p<0.05). The average CMC showed a significant increase in the beta band during motor stimulation (p<0.05). Conclusion: The intensity of FES, which causes actual movement, increased the CMC during action observation. These results show that the intensity of the FES can affect the functional connection between the sensorimotor cortex and muscle.
