“…Vibration stimulation acts on the α-motor neurons, causes contraction of the muscle belly and tendons, and thereby gives rise to myotonic vibration reflection 15 , 16 ) . This increase in the proprioceptive sense of the muscle is thought to increase muscular activity, as it enables the muscle to carry a greater external load 17 ) . The vibration stimulation caused by the Flexi-bar exercise program stimulates the mechanical receptors of the articular capsule of the lumbar joints, enables greater control of posture and motor sense, and improves stability between spinal segments 15 , 16 , 17 ) .…”

[Purpose] This study aimed to determine the effect of a Flexi-Bar exercise program with vibration stimulation on pain and dysfunction in patients with low back pain. [Subjects and Methods] This study included 30 patients with low back pain. The participants were divided into a control (n=15) group and an experimental group (n=15). General physical therapy was used in both groups. A Flexi-Bar exercise program with vibration stimulation was used in the experimental group. The Visual Analog Scale was used to measure pain severity. The Oswestry Disability Index was used to measure the extent of dysfunction due to low back pain. [Results] The VAS and ODI of the experimental group showed a significant difference compared to that of the control group. [Conclusion] The results show that a Flexi-Bar exercise program with vibration stimulation is effective in alleviating pain and dysfunction in patients with low back pain.

“…In contrast, Chung et al. 16 ) reported different results for the effect of the Flexi-Bar exercise on the activation of trunk muscles. The Flexi-Bar exercise showed greater external weight effect compared to the use of a non-vibrating bar, with clear differences in the activation of the internal oblique and external oblique muscles.…”

Abstract.[Purpose] The purpose of this research was to determine the effect of Flexi-Bar exercise with vibration on trunk muscle thickness and balance in university students in their twenties. [Subjects and Methods] This research evaluated 26 university students in their twenties, equally and randomly divided into two groups. Both the experimental and control groups used an ordinary pole for exercise. In addition, the experimental group exercised by using a Flexi-Bar. Ultrasonic imaging was used to measure the changes in trunk muscle thickness. A balance measuring equipment was used to measure balance ability.[Results] The thickness of the transversus abdominis and the multifidus muscles in the experimental group increased, and the experimental group showed increased thickness in the transversus abdominis muscle compared to the control group. After 6 months of exercise, there was an improvement in the blind Romberg test and center of pressure moving distance with one-leg standing. [Conclusion] These results indicate that the Flexi-Bar exercise is effective in increasing trunk muscle thickness and improving balance.

“…24 These results were consistent with a previous study that showed that quadruped, standing, and side-bridging positions with a fleixbar was associated with higher IO muscles activation. 19 Goncalves et al 25 reported that the IO muscles presented a 72% greater muscle activity during the exercises performed with a flexible pole than with a non-flexible pole.…”

“…Chung et al 19 suggested that surface electromyography of selected trunk muscles was measured with RA, EO, IO, and ES muscle in quadruped, sidebridging, and standing positions, so that flexible pole exercises are useful in the activation of trunk muscles.…”

Objective: This study aimed to determine the efficacy of flexible pole training combined with lumbar stabilization in improving trunk muscle activities and to investigate the difference according to posture in young adults. Methods: Twenty-five participants were enrolled in this study. The subjects were randomly allocated into either the flexible pole group or the rigid pole group. Participants performed lumbar stabilization exercises on quadruped and curl-up, with the flexible pole or rigid pole. Electromyography was used to assess the percent maximal voluntary isometric contracion (%MVIC) of the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spine (ES) muscles. All participants completed one 30-minute session per day, 3 days per week, for 6 weeks. The evaluation was performed before and 6 weeks after the training, and follow-up. The data were analyzed using independent t-test and two-way repeated measure analysis of variance to determine the statistical significance. Results: The flexible pole in curl-up showed significant differences in EO and IO muscle activities compared with the rigid pole. The flexible pole in quadruped showed significant differences in IO and ES muscle activities compared with the rigid pole. The RA, EO, IO, and ES muscle activities of both groups were significantly higher after 6 weeks training. Conclusion: The flexible pole in curl-up and quadruped showed an improvement in trunk muscle activation. The flexible pole combined with lumbar stabilization will be useful as an exercise tool to improve activity of trunk muscles.
