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.

Objective : This paper provides a narrative review of the research literature on the neurophysiological and neurochemical mechanisms of local vibration while studying the treatment principles and mechanisms of Whidam's vibrator Sugi therapy. Methods : Searches related to vibration therapy research were conducted in PUBMED using "Vibration", "Whole Body Vibration", "Localized Vibration", and "Focal Vibration". The Conditions were limited to review and systematic review. Results : Roberto Casale's paper was selected as an inquiry task and reviewed critically and narratively by referring to other papers. The stimulation process of local vibration (LV) was broadly classified into receptor transmission (pain reception phase), ascending sensory pathway to the spinal cord (segmental phase), and action of the cortex and subcortical structures (systemic control phase) according to the pain pathway. In addition, the role of C-tactile mechanoreceptors, changes in neurotransmitters and neurohormones, LV stimulation below perception threshold (lower threshold), pain control and kinesiologic illusions were specially addressed. In addition, the expression and function of Piezo Channels were added to supplement the human pain and tactile sensing mechanism. Conclusions : LV exerts pain control mechanisms through different interactions that can interfere with pain transmission and pain perception. Since LV provides sufficient neurophysiological reasons for clinical application, it is necessary to expand the use of Whidam's vibrator Sugi therapy to a wider range of clinical applications.

Objective: Whole body vibration (WBV) and plyometrics are common training techniques which increase strength, blood flow, and lower body force and power. The effects these techniques have on sedentary population is unknown. It is our aim to assess the effectiveness of WBV and plyometrics on sedentary population. Design: Experimental study. Methods: Twenty-seven sedentary subjects were assigned to either the control group, jumping only group, or jumping with vibration group. Jump height (myotest or vertec), velocity, force, blood lactates, and rating of perceived exertion (RPE). Subjects were measured on the initial, seventh, and eighteenth visits. Control group attended measurements only. Jumping only and jumping with vibration groups performed jumping from a vibrating platform to a surface 7 1/2 inches higher for 3 bouts of 20 seconds. Each subject in jumping only and jumping with vibration groups attended three times per week for six weeks. Vibration was set at 40 Hz and 2-4 mm of displacement. Results: There was no significant change among groups in force, velocity, vertec height, and myotest height. However there was a significant increase in vertec height from initial to final measure (p<0.05) for jumping with vibration group. RPE was significantly higher between control group and jumping with vibration group after intervention (p<0.05). Conclusions: WBV with vibration increased jump height. Jumping with vibration group experienced increased exertion than for controls. WBV with plyometrics had no effect on force, velocity, blood lactates, or calculated jump height. Further studies controlling for initial measure of blood lactates and using an external focus may be necessary to elicit velocity, force and jump height changes.

Background: Several factors contribute to shoulder pain, including abnormal neck posture, repeated use of the upper limbs, work involving raising the upper limbs above the head, and the effects of vibration. However, previous study has reported that constant vibration exposure could impact improvement of the stability on joints related with muscle recruitment and activation. For this difference reason, we need to verify for the complex study of relationship with repetitive upper limb movements, poor head posture, and constant vibration exposure. Objects: Our study was made to investigate the influence of vibration exposure on the shoulder muscle activity during forward-head and over-head tasks with isometric shoulder flexion. Methods: In a total of 22 healthy subjects, surface electromyography (EMG) data were collected from shoulder muscles (upper/lower trapezius, serratus anterior, and lumbar erector spinae) on tasks (neutral-head task [NHT], forward-head task [FHT], and over-head task [OHT]) with and without vibration exposure. Results: In all tasks, the EMG data of the upper trapezius and serratus anterior significantly increased with vibration exposure (p < 0.05). Furthermore, the EMG data of the lumbar erector spinae significantly increased with vibration exposure in the NHT and FHT (p < 0.05). Conclusion: We suggest that continuous vibration exposure during the use of hand-held tools in the tasks could be associated with harmful effects in the workplace. Lastly, we clinically need to examine the guidelines regarding the optimal posture and vibration exposure.

Background: Although studies have been conducted on muscle thickness and balance in trunk stabilization exercise and exercise using vibration props, studies on trunk stabilization exercise using active vibration for spinal alignment are still insufficient to draw a conclusion. Objectives: To investigate the effect of trunk stabilization exercise using active vibration on the spinal alignment in adult females. Design: A randomized controlled trial. Methods: Twenty-six adult females were randomly assigned to the experimental group (active vibration) and 13 control groups (active non-vibrating) and exercised three times a week for 8 weeks. Each group was measured for spinal alignment before exercise and 8 weeks after exercise. Spinal alignment, trunk imbalance, pelvic tilt, and pelvic torsion were measured using a spinal alignment analyzer. Results: Trunk imbalance was a significantly different depending on the time in the experimental group and the control group (P<.05). Pelvic tilt was a significant difference between the groups (P<.05). Also, pelvic tilt was a significantly different depending on the time in the experimental group (P<.05), but the control group showed no significant difference (P>.05). Pelvic torsion was no significant difference in both groups (P>.05). Conclusion: This study demonstrates that trunk stabilization exercise using active vibration has a positive effect on the alignment of the spine.

Purpose : This study focuses on the influence of bridge exercise combined with whole body vibration on muscle activity and balance. Methods : 30 stroke patients were recruited for subjects. The subjects were divided to bridge exercise combined stable surface (Group I), bridge exercise combined unstable surface (Group II), and bridge exercise combined bridge exercise (Group III), of which 10 subjects were randomly allocated. The subjects were given 30 minutes of neurologic physical therapy which included gait training and muscular strength training, and additionally given 30 minutes of bridge exercise combined stable surface, bridge exercise combined unstable surface, and bridge exercise combined whole body vibration for each group, five times a week, for 8 weeks. Their muscle activity and balance were analyzed before the intervention. After 8 weeks of the intervention, the mentioned parameters were measured once more for between-group analysis. Results : Comparative analysis of the muscle activity and balance between the groups showed statistically significant difference, and post-hoc analysis showed the Group III had greater changes in muscle activity and balance than Group Iand Group II. Conclusion : Such results revealed that bridge exercise combined with whole body vibration is effective in muscle activity and balance. Based on the current study, more effective program is to be proposed for elite athletes as well as stroke patients. Based on the current study, studies that incorporates various frequencies of vibration is required for development of effective whole body vibration exercise program.

Purpose: This study examined the effect of vibration exercise on the thickness of the oblique extrinsic, oblique abdominal, and biceps muscles, which are trunk muscles, targeting children with spastic cerebral palsy. Methods: The participants in this study were 20 children (8 male and 12 female) with cerebral palsy aged 5-10 years. They were classified into two groups using a randomized allocation method, and the trunk muscle thickness was measured using an ultrasound-imaging device before and six weeks after the experiment. A paired t-test was used for the within-group changes, and an independent t-test was used for the inter-group changes. The significance level was set to α=0.05. Results: There was a significant increase in the inter-group change in the experimental group and control group in the intra-group change in the external oblique muscle and internal oblique muscle. After six weeks, there was a significant increase in the experimental group compared to the control group. Conclusion: Vibration exercise had a positive effect on the trunk muscle thickness of children with cerebral palsy. Vibration exercise produced a significant difference in the changes in the trunk muscle thickness in children with cerebral palsy compared to no vibration exercise. These results may provide basic data for future research and as a training method for strengthening the trunk muscles in clinical trials.
