The use of electricity to evoke s skeletal muscle response is FES, which is a form of functional electrical stimulation. In the case of the damaged spinal cord, the technique can supply stimulation to the lower moter neurons and their muscle fiber, which have been disconnected from control of the higher nervous system. Recent advances in electronics, particularly miniaturization, have made possible the design of much improved systems of electrodes and stimulaters for FES. Clinical research has followed two main lines: the use of FES in the upper extremities for producing functional hand rehabilitation in quadriplegics and in the lower extremities for producing standing and gait in paraplegics.

Functional Electrical Stimulation(FES) cause paralysed muscles to contract in some clinical circumstances. Generally, FES has been thought of as a valuable tool in activating any skeletal muscle paralysed as a result of upper motor neuron damage. But, the function of cardiac and smooth muscle is also affected by upper motor neuron damage. Today, various applications of FES are investigated, including conditioning cardiovascular exercise, caugh and breathing assistant, improving bowel and bladder control, hand grasp, standing and walking etc. This review will focus on the literature reporting application of FES to control respiratory capabilities and internal organ function as well as increase muscular strength, hand grasp, standing and walking in patients with upper motor diseases.

Purpose : The purpose of this study was to investigate the effect of electrical stimulation applied in dominant forearm on autonomic nervous system response of both hands. Methods : Fourteen healthy subjects (women) received low frequency-high intensity electrical stimulation to one forearm. The subjects assigned to two groups; a ipsilateral stimulation group (n=7) and a contralateral stimulation group (n=7). The electrode attachment was arranged on the forearm of the dominant arm and the electricity stimulus time was set as 15 minutes. Measuring items were the skin conduction velocity, the blood flow, and the pulse rate, which were measured total 3 times (pre, post, and post 10 min.). Results : The skin conduction velocity showed a significant difference according to the change of the time in both hands, but there was no significant difference according to time in the blood flow, and the change of the pulse frequency regardless of stimulus side. Conclusion : These results demonstrate that the low frequency-high intensity electrical stimulation applied dominant forearm can increase selectively only with the skin conduction velocity, which may be helpful for the activation of the sudomotor function of both hands by the activation of sympathetic nerve.

PURPOSE: The purpose of this study was to investigate the effect of weight shift training with electrical sensory simulation feedback on quiet standing balance in hemiplegic stroke patients. METHODS: 30 stroke patients were equally allocated at random to an experimental group or a control group. Patients in both two groups underwent comprehensive rehabilitation physical therapy for 30 minutes per day for 5 days per week for 4 weeks. Members of the experimental group received additional weight shift training with electrical sensory simulation feedback was conducted for 15 minutes after 30 minute sessions, whereas members of the control group underwent additional leftward/rightward weight shift training by themselves after 30 minutes per day for four weeks. COP (center of pressure) path lengths, COP velocities, and foot forces were measured before and immediately after the 4-week training period in both groups and results were compared. RESULTS: COP path lengths significantly decreased by 3% after training in the experimental group and this was significantly greater than that observed in the control group (p<0.05). In both groups, foot forces of affected sides showed significant increases after intervention, whereas foot forces of unaffected sides showed significant decreases (p<0.05). No significant difference was observed between the two groups with respect to these changes. CONCLUSION: Weight shift training using electrical sensory simulation feedback has a positive effect on quiet standing balance in hemiplegic stroke.

PURPOSE: The purpose of this study was to identify the effects of physical therapy plus Kinesio taping (KT) on muscle tone and stiffness in patients with shoulder pain. METHODS: This study included 22 participants who were divided into the experimental group (n=11) who underwent a routine physical therapy with KT and the control group (n=11) who received the same physical therapy only. The physical therapy consisted of heat application and electrical stimulation. Heat was applied for 10 minutes and electrical stimulation was conducted for 20 minutes. Intervention was provided over a 1-week period, and frequency for muscle tone and stiffness was measured to determine changes in shoulder muscle status. The muscles were supraspinatus and deltoid. Measurements were taken before, after 1day, 3day and after 1 week to identify time-dependent effects of intervention. RESULTS: The effects of the intervention were significant in both groups, and effects were greater in the experimental group. Changes in muscle tone and stiffness were statistically significant in both groups and at varying time points (p<.05). CONCLUSION: Based on the improved muscle performance found in this study, KT is considered an effective intervention strategy for patients with shoulder pain when it is combined with conventional physical therapy.

The purpose of this study was to assess the effectiveness of scapular pattern of PNF on the pain level in whiplash injury patients. Pain level were assessed prior, after first, after second, after third, after fourth, and after fifth treatment. All 6 times were calculated pain level. To find out the effectiveness of scapular pattern of PNF, we were divide two groups. The one group was consisted of 25 patients that were treated with H/P electrical therapy and MFR, and the other group was consisted of 25 patients that were treated with H/P, electrical therapy, and scapular pattern of PNF. The results were as follow: 1. There were statistical significance on the pain level in MFR group during all treatment periods(p<0.05). 2. There were statistical significance on the pain level in scapular pattern of PNF group all during treatment periods(p<0.05). 3. Scapular pattern of PNF group had more statistical significance than MFR group on the pain level during all treatment periods(p<0.05). Consequently, this study suggest that scapular pattern of PNF technique has a very effectiveness to the whiplash injury patients.

Devices in current market to perform electrical stimulation therapy of the urinary incontinence frequent in aging women are very much impractical to us ε due to the wired configuration. The present study implemented new wireless device to enhance self as well as in-hospital therapy with the easiest and the most convenient application. The therapy system consisted of two modules, called 'master' and 'slave', communicating with each other by the wireless Bluetooth protocol. The patient controls therapy processes on the master module in hand, transmitting the required informations to operate the slave module placed within her pants with the viginal electrode connected, delivering appropriate electrical stimulation. Wireless communication enabled self therapy with clothes on, leading to a great convenience for the patient. The stimulation output signal was comparable to commercialized products in both waveform and stimulation capacity.

Objective: To investigate the action observation effects of functional electrical stimulation (FES) on the communication between motor cortex and muscle through corticomuscular coherence (CMC) analysis. Methods: Electroencephalogram (EEG) and electromyogram (EMG) of 27 healthy, nonathlete subjects were measured during action observation, FES, and action observation with FES, which lasted for 7sper session for 10 times. All trials were repeated for 30 times. Simultaneously measured EEG raw data and rectified EMG signals were used to calculate CMC. Only confidence limit values above 0.0306 were used for analysis. CMC was divided into three frequency domains, andthe grand average coherence and peak coherence were computed. Repeated ANOVA was performed to analyze the coherence value difference for each condition's frequency band. Results: CMC showed significant differences in peak coherence and average coherence between the conditions (p<0.05). Action observation application with FES in all frequency band showed the highest peak and average coherence value. Conclusions: The results of this study are assumed to be the combination of increased eccentric information transfer from the sensorymotor cortex by action observation and an increased in concentric sensory input from the peripheral by the FES, suggesting that these are reflecting the sensorimotor integration process.
