  • 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 conducted to investigate the effects of combined Joint Mobilization and Functional Electrical Stimulation on Muscle Activation and Mobility of ankle joints in stroke patients and their Modified Functional Reach Test (MFRT) results. METHODS: A total of 26 patients with stroke were randomly selected for enrollment in this study. (1) Functional Electrical Stimulation (FES) (2) combined Joint Mobilization and FES. An EMG system was used to measure tibialis anterior and gastrocnemius activities. Range Of Motion (ROM) of Ankle Joint and MFRT for Dynamic Balance. Pre and post intervention results were compared by paired-t-tests and differences in changes after intervention between groups were identified by the independent t-test. RESULTS: The muscle activation, ROM, and MFRT differed significantly in the experimental group (p<.05). The ROM was significantly different for the active dorsiflexion pre and post intervention in the group that received FES alone (p<.05). CONCLUSION: The results of this study suggest use of a systematic program of proactive posture control to prevent dysfunction when planning interventions for ankle joints can help stroke patients walk efficiently.

  • Purpose : This study was conducted to evaluate the effects of FES with abdominal muscle contraction before virtual reality training on balance and gait ability in patients of stroke patients. Methods : The subjects were 30 stroke patients who satisfied the selection criteria. They were randomly assigned to a group receiving functional electrical stimulation with a virtual reality training program (the experiment group, n=15) and placebo functional electrical stimulation with a virtual reality training program (the control group, n=15). The program consisted of three 30-min sessions per week for six weeks. The timed up and go test (TUG), the BT4, the G-WALK were used to estimate subjects' balance, gait before and after the program. For the experiment group, the functional electrical stimulation was applied to the external oblique and the rectus abdominis, For the control group, the same program and the placebo functional electrical stimulation were applied. Results : There were significant improvements in the subscales of the balance and gait ability test of those who participated in the functional electrical stimulation, while the control group showed no significant changes. Conclusion : Therefore, functional electrical stimulation with virtual reality effectively improved the balance and gait ability in patients with chronic stroke.

  • Purpose: This study aimed to assess the effectiveness of gait training with the use of an electromechanical gait trainer with functional electrical stimulation (FES) for patients that had undergone subacute stroke. Methods: The study subjects included nine subacute stroke patients of the Korea National Rehabilitation Center in Seoul, Korea. Outcome was measured using the timed Up and Go test, Fugl-Meyer-L/E assesment, with determination of the comfortable maximal gait speed, composite spasticity score, functional ambulatory category and Berg balance scale. All measured scores were recorded before, during, and after rehabilitation and at an eight-week follow-up. Results: Patients who received electromechanical-assisted gait training in combination with FES after subacute stroke were more likely to achieve independent walking, functional activities, balance and gait speed. Conclusion: The outcome of our gait-training program demonstrates that it may be practical to integrate FES into electromechanical gait training without any adverse effects. However, further randomized controlled studies are needed to evaluate if patient outcome after combined training is superior to outcome after the use of electromechanical gait trainer treatment alone or conventional gait training alone.

  • This paper deals with an experimental study on the reaction of muscles by functional electrical stimulation(FES) with the design and fabrication of an ankle reaction apparatus. The ankle reaction apparatus consists of a circuit part and a kinematic part, and it monitors reaction time for a particular angle of joint rotation according to FES. The experimental results showed that the change of the ankle rotation angle was linearly proportional to the change of the magnitude of FES. It also showed that the muscle's reaction time was constant no matter how large the magnitude of the stimulus. The results of this paper can be applied to develop an active-type walking-assistance robot.

  • PURPOSE: This study aimed to compare the impact of exercise with that of functional electrical stimulation (FES) and transcutaneous electrical nerve stimulation (TENS) on muscle tone, calf muscle stiffness, and balance ability in patients with stroke. METHODS: Thirty patients with stroke were randomly divided into an FES group (n=15) and a TENS group (n=15), and a progressive task-oriented exercise was assigned to them. These exercises were performed non-synchronously from December 5, 2016 to January 31, 2017. Patients underwent TENS and simultaneously exercised for 30 minutes daily, 5 times a week for 4 weeks. To determine the effect of the interventions, muscle tone and stiffness of the medial and lateral region of gastrocnemius muscle were measured using the MyotonPRO instrument and balance was assessed using the Berg Balance Scale. RESULTS: Both groups revealed a significant decrease in muscle tone and stiffness of the medial part of gastrocnemius muscle before and after the interventions (p<.05). Berg Balance Scale scores increased significantly (p<.05). However, none of the other parameters were significantly different (p>.05). CONCLUSION: Our results prove that progressive task-oriented exercise along with FES and TENS decreases muscle tone and stiffness of the gastrocnemius muscle in patients with stroke and improves balance. TENS could serve as a complementary replacement for functional electrical stimulation for in-house training, as TENS poses less risk of muscle fatigue and has lesser contraindications than does functional electrical stimulation.

  • Objective: The weakness of muscle strength due to stroke affects the posture control and gait in the patients with stroke. Stroke This study examined the effects of the stair climbing training with functional electrical stimulation on muscle strength, dynamic balance, and gait in individuals with chronic stroke. Design: Randomized controlled trial. Methods: Total forty-eight patients were randomly assigned to the 3 groups. Participants randomly divided to stair climbing training with functional electrical stimulation group (SCT+FES group, n=16), stair climbing training group (SCT group, n=16) and control group (n=16). Subjects in the SCT+FES group and SCT group performed stair walking training with and without functional electrical stimulation for 30 minutes, 3 sessions per week for 4 weeks and all subjects received conventional physical therapy for 30 minutes with 5 sessions per week for 4 weeks. Outcome measurements were assessed using the sit-to stand Test for strength, timed up and go test and modified-timed up and go test for dynamic balance, and 10m walk test and GaitRite system for gait. Results: In the SCT+FES group, subjects have been shown the significant increase in lower extremity strength (p<0.05), significantly improve in dynamic balance (p<0.05), and significantly improve in their temporal gait parameter (p<0.05). The SCT+FES group was significantly better than other groups in all parameters (p<0.05). Conclusions: This result suggested that the SCT+FES may be effective strategy to improve muscle strength, dynamic balance, and gait for individuals with chronic stroke.

  • Purpose: The purpose of this study was to compare the effects of the FES-gait with augmented feedback training to the FES alone on the gait and functional performance in individuals with chronic stroke. Methods: This study used a pretest and posttest randomized control design. The subjects who signed the agreement were randomly divided into 12 experimental groups and 12 control groups. The experimental groups performed two types of augmented feedback training (knowledge of performance and knowledge of results) together with FES, and the control group performed FES on the TA and GM without augmented feedback and then walked for 30 minutes for 40 meters. Both the experimental groups and the control groups received training five times a week for four weeks. Results: The groups that received the FES with augmented feedback training significantly showed a greater improvement in single limb support (SLS) and gait velocity than the groups that received FES alone. In addition, timed up and go (TUG) test and six minute walk test (6MWT) showed a significant improvement in the groups that received FES with augmented feedback compared to the groups that received FES alone. Conclusion: Compared with the existing FES gait training, augmented feedback showed improvements in gait parameters, walking ability, and dynamic balance. The augmented feedback will be an important method that can provide motivation for motor learning to stroke patients.

  • PURPOSE: This study examined the effects of functional electrical stimulation (FES) on temporal-spatial gait and the activities of daily living in hemiplegic stroke patients. METHODS: The subjects were 29 hemiplegic stroke patients (57.7 ± 10.3). The patients walked at a self-controlled speed in four states: (1) walking without FES (non-FES), (2) walking with FES on the gluteus medius in the stance phase (GM), (3) walking with FES on the common peroneal nerve and tibialis anterior in the swing phase (PT), (4) walking with both GM and PT. A GAITRite system, Timed-Functional Movements battery, and Timed UP and Go test were used to measure the variables. RESULTS: Significant improvements were observed in all variables of the GM+PT, GM, and PT states compared to the non-FES state (p < .05). There were significant improvements in the GM+PT state compared to GM and PT states (p < .05). Moreover, significant improvements were noted in the single support time on the affected side, backward walking 10ft, and side stepping 10ft on the affected side of the GM state compared to the PT state (p < .05). There were significant improvements in the stride length on the affected side and side stepping 10ft on the unaffected side of the PT state compared to the GM state (p < .05). CONCLUSION: FES is effective in improving the temporal-spatial gait and activities of daily living in hemiplegic stroke patients.

  • The purpose of this single subject care study was to evaluate the effectiveness of a functional electrical stimulation(FES) treatment program designed to prevent glenohumeral pint stretching and subsequent subluxation and shoulder pain in hemiplegic patients. The subject was a 43-year-old male who had left side hemiparesis with shoulder pain and subluxation on affected side. He received conventional physical therapy and additional FES therapy where two flaccid shoulder muscles, supraspinatus and posterior deltoid. were induced to contract repetitively up to 20 minutes for 2 weeks. As a result. the patient showed improvements in hemiplegic arm function, reduction in subluxation(as indicated by Jig test) and range of motion(SLROM). But it was difficult to generalize. We concluded that the FES program was effective in reducing the severity of shoulder subluxation and pain. Further study must be evaluated its statistical significance.
