Objective: This study aimed to determine the effect of proprioceptive neuromuscular facilitation (PNF) balance exercise on the ability to balance and walk in patients with hemiplegia caused by stroke. Design: A randomized controlled trial Methods: Following baseline measurements, patients (n=24) with hemiplegia caused by stroke were randomized into two groups: the PNF balance group (n=12) that received PNF balance exercise and the balance group (n=12) that received general balance exercise. Each group joined the intervention for 30 minutes, 5 times per week for 6 weeks. Both groups performed the Timed Up and Go test (TUG) and Berg Balance Scale (BBS) for balance, as well as the 10-meter walking test (10MWT) and 6-minute walk test (6MWT) for walking. The data were collected both before and after the intervention. The paired t-test was used to compare the post-intervention changes compared with pre-intervention data. An independent t-test was used to analyze the differences in the dependent variables between the two groups. Results: After the 6-week intervention, both groups showed significant improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) parameters (p<0.05). The patients in the PNF balance group showed greater improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) than those in the balance group (p<0.05). Conclusions: PNF balance exercise shows improvements in balance and walking parameters in patients with hemiplegia caused by stroke.

Background: This study was conducted to investigate the effects of pressure belt during proprioceptive neuromuscular facilitation sprinter pattern training using a Thera-band on leg muscle strength and gait in stroke patients with stroke. Methods: Nine patients with stroke underwent training five times a week for four weeks, and changes in the muscle strength and walking ability of the paralyzed leg before and after training were measured. Muscle strength was measured using a Digital muscle tester, and walking ability was measured using a G-WAKER and the timed up and go (TUG) test. Results: Results showed that the quadriceps, hamstring, tibialis anterior, gastrocnemius, cadence, stride length, and stance phase significantly increased (p<.05). The swing phase, gait cycle duration, and TUG test results significantly decreased (p<.05). Conclusion: This study demonstrated that a pressure belt is a very useful tool for improving muscle strength and walking ability in patients with stroke.

Background: Stroke patients have weak trunk muscle strength due to brain injury, so a single type of exercise is advised for restoring functionality. However, even after intervention, the problem still lies and it is suggested that another intervention method should be applied with exercise in order to deal with such problem. Objectives: To Investigate the effect of bridge exercise combined with functional electrical stimulation (FES) on trunk muscle activity and balance in stroke patients. Design: Randomized controlled trial. Methods: From July to August 2020, twenty stroke patients was sampled, ten patients who mediated bridge exercises combined with functional electrical stimulation were assigned to experiment group I, and ten patients who mediated general bridge exercises were assigned to experiment groupII. For the pre-test, using surface EMG were measured paralyzed rectus abdominis, erector spinae, transverse abdominis/internal oblique muscle activity, and using trunk impairment scale were measured balance. In order to find out immediate effect after intervention, post-test was measured immediately same way pre-test. Results: Change in balance didn't show significant difference within and between groups, but muscle activity of trunk was significant difference rectus abdominis and erector spinae within groups I (P<.01), also between groups was significant difference (P<.05). Conclusion: Bridge exercise combined with FES could improve trunk function more effectively than general bridge exercise due to physiological effect of functional electrical stimulation.

Purpose: New therapeutic approaches have emerged to improve gait ability in patients with brain damage, such as action observation learning (AOT), auditory cueing, motor imagery etc. We attempted to investigate the effects of AOT with auditory cueing (AOTAC) on gait function in patients with stroke. Methods: The eighteen stroke patients with a unilateral hemiparesis were randomly divided into three groups; the AOTAC, AOT, and control groups. The AOTAC group (n=8) received training via observing a video that showed normal gait with sound of footsteps as an auditory cue; the AOT group (n=6) receive action observation without auditory stimulation; the control group (n=5) observed the landscape video image. Intervention time of three groups was 30 minutes per day, five times a week, for four weeks. Gait parameters, such as cadence, velocity, stride length, stance phase, and swing phase were collected in all patients before and after each training session. Results: Significant differences were observed among the three groups with respect to the parameters, such as cadence, velocity, stride length, and stance/swing phase. Post-hoc analysis indicated that the AOTAC group had a greater significant change in all of parameters, compared with the AOT and control groups. Conclusion: Our findings suggest that AOTAC may be an effective therapeutic approach to improve gait symmetry and function in patients with stroke. We believe that this effect is attributable to the change of cortical excitability on motor related to cortical areas.

Objectives: Objectives : This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the patients with Post-stroke Urinary Retention; PSUR. Methods: Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUR compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions: 4 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUR. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as SP6, CV3, CV6, CV4, SP9, BL28, BL23, BL22, KI3 or BL67, for 15-30 minutes. 20-140Hz frequency and 10-20 minutes of treatment is suggested if electro-acupuncture treatment is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. Finally, there was a moderate evidence to support safety of acupuncture treatment for PSUR.

Purpose: The purpose was to determine whether the application of the abdominal drawing-in maneuver (ADIM) and abdominal expansion maneuver (AEM) to stroke patients would affects their trunk stability, balance, pulmonary function, and grip strength. Methods: The subjects were 36 stroke patients who were randomly and equally assigned to an ADIM group (n=12), an AEM group (n=12), and a control group (n=12). The intervention was applied to each group three times per week, 30 minutes each time, for four weeks. Outcome measures were grip strength, modified functional reach test (mFRT) and pulmonary function. Pulmonary function were measured force expiratory volume at one second (FEV1), forced vital capacity (FVC), FEV1/FVC and peak expiratory flow (PEF) values. Results: The results of the three groups showed statistically significant improvements in grip strength. The AEM group showed significantly greater differences in grip strength than either the ADIM group or the control group. In the anterior mFRT, the ADIM group showed significantly improvements than the control group. The ADIM and AEM groups were showed statistically significant greater improvements in PEF between the baseline and post-intervention and the post-analysis revealed that the AEM group showed significantly greater improvements than the control group. Conclusion: The results of this study indicate that the ADIM and AEM were effective in improving the PEF of pulmonary function. The ADIM was more effective than AEM in trunk stabilization.
