  • Objective : This systematic review aimed to investigate the effect of focal muscle vibration in patients with post-stroke spastic hemiplegia. Methods : We searched literature published between April 2009 and October 2017 using PubMed and RISS databases. The main search terms were Vibration therapy, Focal vibration, Somatosensory, Upper limb, and Spasticity after stroke. Based on inclusion/exclusion criteria, 6 articles were selected. Results : Articles on focal muscle vibration intervention ranged from evaluation of application-only vibration to muscle vibration with task-oriented activity. Intervention effects on upper extremity spasticity and function and activities of daily living were assessed. There were significant effects on upper extremity spasticity, function, and cortical excitability. Conclusions : This study can provide information on focal muscle vibration for use by clinical therapists. However, further studies are needed to identify the optimal stimulation site and frequency/amplitude of application to maximize the effects of focal muscle vibration.

  • The purpose of this study was to investigate the convergence effect of focal vibration stimulation and bilateral upper limb training on the recovery of upper limb function when applied to stroke patients. For 20 stroke patients, divided into an experimental group that performed convergence intervention with focal vibration stimulation and bilateral upper limb training, and a control group who performed only bilateral upper limb training. It was conducted 20 times for 4 weeks, 30 minutes per session. Vibration stimulation was applied to the affected side of the experimental group for 30 minutes during training. Results were measured for the degree of recovery of the affected upper limb function, amount of use on the affected and unaffected sides, the quality and satisfaction in performance on use of both upper limbs. Comparisons were made within groups using a paired-sample t-test and between groups using covariance analysis. As a result of the study, the experimental group showed a significant difference in dexterity and the amount of use on the affected than the control group. The effect size was more than the small effect size in all evaluation items. Through this study, it is thought that the convergence intervention of focal vibration stimulation and bilateral upper limb trainingcan be used clinically as an effective intervention for the recovery of arm function in stroke patients.

  • Objective : Localized vibration has been shown to have a positive effect on recovery of upper-limb motor function in patients with hemiparetic stroke, but there has been little research on kinematic analysis for qualitative changes in movement. This study investigated kinematic changes in elbow motion during reaching after localized vibration in persons with hemiparetic stroke. Methods : This study used a one-group, cross-over trial design. Ten chronic stroke patients randomly received localized vibrations on the affected biceps brachii for 5, 10, or 20 min, at 70 Hz. Kinematic analysis of reaching was measured using a 3-D motion analysis system. Variables included peak angular velocity, time to peak angular velocity, and movement units during elbow motion. Result : Affected side elbow motion during reaching was faster, smoother, and more efficient after 20 min localized vibration. Peak angular velocity increased (p<0.05), and time to peak angular velocity (p<0.05) and the movement unit were significantly decreased (p<0.05) during elbow motion for reaching. Conclusion : Localized vibration can improve kinematic components during reaching motion in persons with hemiparetic stroke.

  • Purpose : To investigate the effectiveness of local vibration and interferential therapy for patient with acute low back pain. Methods : A randomized trial designed to compare interferential therapy and local vibration therapy for acute low back pain in primary care setting Results : A total of 60 patients were recruited. The two treatment groups had similar demographic and clinical baseline characteristics. The mean VAS scores before treatment was 8.290 for interferental therapy group and 8.572 for local vibration therapy groups. After treatment, this VAS score had dropped to 4.812(interferental therapy group, at 7 days), and 4.945(local vibration group, at 7 days). Conclusion : This study shows a progressive fall in visual analog scale scores in patients with acute low back pain treated with either interferential therapy and local vibration therapy. There was some difference in the improvement between the two groups at 1 to 4 days, VAS score of vibration therapy groups was low better than interferential therapy groups.

Effects of Simultaneous Application of Focal Vibration Stimulation and Task-Oriented Training in the Improvement of Upper Extremity Motor Function after Stroke (국소 진동자극과 과제 지향적 훈련의 동시 적용이 뇌졸중 환자의 상지 기능 개선에 미치는 효과)

  • Purpose : The purpose of this study was to determine the effects of simultaneous application of focal vibration stimulation and task-oriented training on the improvement in upper extremity motor function after stroke. Methods : The study period was from January to April 2019; 23 patients who fulfilled the study eligibility criteria were enrolled. The participants were divided into two groups: the experimental group with vibration stimulation and task-oriented training and the control group with only task-oriented training. Training was conducted in a total of 20 sessions, 5 times a week for 30 minutes a day for 4 weeks. The amount of use of the affected and unaffected side by accelerometers, and Box and Block test (BBT), Action Research Arm Test (ARAT) was measured with a pre-test, a post-test. Wilcoxon Signed Rank Test and Analysis of Covariance were used to compare and analyze the changes within and between the groups. Results : Both the groups showed statistically significant changes in the results of the BBT and the ARAT, as well as the amount of use of the affected and unaffected side. Regarding the use of the affected side, BBT results, and the grasp and gross movement item of the ARAT showed significant changes in the experimental group compared with the control group. Conclusion : We found that simultaneous application of focal vibration stimulation and task-oriented training was more effective than task-oriented training alone. A large-scale comparative study involving a group that is only given vibration stimulation should be conducted for more generalizable results.
