The purpose of this study was to assess the effect of rehabilitation exercise and neuromuscular electrical stimulation on a visual analysis scale and functional visual analysis scale regarding functional capacity. A total of 7 consecutive patients with the complaint of patellofemoral pain syndrome who received this diagnosis from a sports medicine physician were recruited to assess the effect of rehabilitation exercise and neuromuscular electrical stimulation (NMES) on Visual Analog Scale (VAS) and Functional Visual Analog Scale (FVAS), functional capacity patients with patellofemoral pain syndrome. The exercise rehabilitation consisted of a complex training program requiring five treatments a week for eight weeks. The training program consisted of four phases, and each lasted for two weeks. Statistical analyses were one-way ANOVA with repeated measures. The results were as follows: (1) There were significant differences in the VAS and FVAS during 8-weeks of rehabilitation exercise and neuromuscular electrical stimulation (p<.01). (2) There were no significant differences in the functional capacity during 8-weeks of rehabilitation exercise and neuromuscular electrical stimulation (p<.05). In conclusion, at the end of the eight weeks of this rehabilitation program and neuromuscular electrical stimulation, a significant reduction was found in VAS and FVAS, but there was no significant difference in functional capacity at the end of the treatment.

Objective: The purpose of this study was to investigate the effects of gastrocnemius neuromuscular electrical stimulation training on ankle mobility and gait in patients with stroke. Design: A randomized controlled trial. Methods: 31 patients with stroke were selected and classified into an experimental group (n=16) and a control group (n=15). Both groups were assessed for ankle mobility using the Knee to Wall Test and gait parameters using G-walk before and after the intervention. The intervention was applied five times a week for four weeks. The experimental group performed gastrocnemius neuromuscular electrical stimulation followed by ankle control exercises, while the control group only applied NMES to the tibialis anterior muscle of the paretic side for 30 min per session five times a week for 4 weeks. Results: Experimental group showed significant improvements in Knee to wall test. and lumbar flexibility after the intervention. both group showed significant improvements in gait parameters after the intervention. However, when comparing between the two groups, the experimental group showed a more significant effect than the control group. Conclusions: Gastrocnemius neuromuscular electrical stimulation training can be considered an effective approach to improve ankle mobility and gait ability in patients with stroke.

PURPOSE: To examine the effects of functional electrical stimulation during gait training on the gait, balance, and lower extremity function of chronic stroke patients. METHODS: A total of 20 subjects diagnosed with chronic stroke were randomly divided into experimental group that performed functional electrical stimulation during gait training, and a control group applied with only functional electrical stimulation, with 10 subjects in each group. RESULTS: In the Berg Balance Scale, the experimental group ranged from 19.80 ± 4.93 to 24.30 ± 6.63 and the control group ranged from 39.40 ± 12.72 to 40.10 ± 13.18, which showed significant differences (p < .05), and there was a significant difference between the groups (p < .05). In 10 Meter Walk Test, the experimental group ranged from 28.70 ± 4.03 to 26.42 ± 3.56, which showed significant differences (p < .05), and there was a significant difference between the groups (p > .05). In Fugl-Meyer Assessment Scale-Lower extremity, the experimental group ranged from 22.70 ± 4.49 to 25.30 ± 4.39 and the control group ranged from 21.10 ± 5.34 to 25.30 ± 4.49, which showed significant differences (p < .05), and there was no significant difference between the groups (p > .05). CONCLUSION: Functional electrical stimulation during gait training may be suggested as an effective program for improving gait, balance, and lower extremity function of stroke patients. Therefore, functional electrical stimulation during gait may be recommended as part of the rehabilitation program for chronic stroke patients.

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.

Purpose: The purpose of this study was to examine the effect of weight-bearing training with an elastic band during functional electrical stimulation (FES) on walking and balance functions in stroke patients. Methods: Twenty patients with chronic stroke were divided into an experimental group assigned to weight-bearing training with an elastic band during functional electrical stimulation (FES; n=10) and a control group assigned to weight-bearing training alone during FES (n=10). The patients in both groups attended physical therapy sessions five times a week for four consecutive weeks. The experimental group underwent weight-bearing training with an elastic band during FES five times a week for four weeks. The control group underwent weight-bearing training during FES. Balance parameters were measured before and after the intervention using the Balancia program. Moreover, all patients were evaluated using the Berg Balance Scale (BBS), the Time Up and Go Test (TUGT), and the Wisconsin Gait Scale (WGS) before and after each intervention. Results: The results showed that weight-bearing training with elastic bands during FES and weight-bearing training during FES had a significant effect on the affected side's weight-bearing ratio, BBS, TUGT, and WGS in both groups (p <0.05). Additionally, the results showed that the changes observed in the two groups indicate significant differences in path length, average speed, BBS score, TUGT time, and WGS score between the groups (p < 0.05). Conclusion: In patients with stroke, weight-bearing training with an elastic band during FES affected on walking and balance. Therefore, it is an optional intervention for the balance and walking ability of stroke patients.

Purpose: To compare the effects of intra-anal biofeedback (BF) and intra-anal electrical stimulation (ES) on pelvic floor muscles (PFMs) activity, nocturnal bladder capacity, and frequency of wet night episodes in children with refractory primary monosymptomatic nocturnal enuresis (PMNE). Methods: Ninety children of both sexes aged 8-12 years with refractory PMNE participated in this study. They were randomly assigned to 3 groups of equal number: control group (CON) that underwent behavioral therapy and PFM training, and 2 study groups (BF and ES) that underwent the same program in addition to intra-anal BF training and intra-anal ES, respectively. PFMs activity was assessed using electromyography, nocturnal bladder capacity was evaluated by measuring the first morning voided volume, and a nocturnal enuresis diary was used for documenting wet night episodes before treatment and after 3 months of treatment. Results: After training, all groups showed statistically significant improvements in all measured outcomes compared to their pretreatment findings. The ES group showed significantly greater improvements in all measured outcomes than the CON and BF groups. Conclusions: Both intra-anal BF training and ES combined with behavioral therapy and PFMs training were effective in the treatment of PMNE, with intra-anal ES being superior to BF training.

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.

Functional electrical stimulation (FES) training of the knee extensors is a useful way to rehabilitate the ability to stand and walk. However, training using FES has not been able to solve the problem of fatigue; clinical application of FES quickly produces muscle fatigue, due to the continuous activation of the muscles of the lower extremity. Therefore, reduction of muscle fatigue is an important factor in increasing the effectiveness of FES training in paraplegia. Intermittent high frequency alternating stimulation is a method that combines the advantages of high frequency (leading to strong muscle contractions) and alternating stimulation (reducing muscle fatigue), thereby continuously strengthening muscles. It is not known whether low frequency simultaneous stimulation results in stronger muscle contraction than high frequency alternating stimulation. This study compared the effectiveness of high frequency alternating stimulation with low frequency synchronized stimulation. Muscle power using FES on the quadriceps of 20 normal subjects were compared. Intermittent high frequency alternating stimulation did not produce more powerful muscle contraction than intermittent low frequency synchronized stimulation, because the muscle characteristics differed individually. Significant individual variation according to muscle characteristics was founded when applying FES. Accordingly, when physical therapists use FES to treat patients, they must be aware of individual variation in muscle characteristics.
