This study was conducted to identify how a flexi-bar exercise influences body alignment and balance in adults who have asymmetry in their right or left body. In total, 20 participants were separated into the experimental group and the comparison group. Those in the experimental group participated in a flexi-bar exercise for 6 weeks and based on the coronal plane before and after exercise, their body alignment and balance were measured behind the body. The result was those who had participated in a flexi-bar exercise significantly improved their angle of acromion on both sides, the difference in the angle and height of the posterior superior iliac spine on both sides(p<.05), and the balance of the center sagittal plane(p<.05). Through this study, it could be said that participating in a flexi-bar exercise would improve postural alignment and balance of the shoulder and pelvis in adults with asymmetric posture.

Background: This study aimed to investigate the immediate effects of Flexi-bar exercise on plantar pressure and Center of Pressure in a standing position. Design: Single group pre-post test design Methods: Thirty healthy adult participants aged 20 to 35 years old and no recent musculoskeletal injuries were included in this single-group pre-post design study. Plantar pressure and COP data were collected using the WinTrack system before and after Flexi-bar exercise. Participants performed Flexi-bar exercises in both anterior-posterior and lateral directions for 30 seconds each. Results: The results revealed significant changes in plantar pressure and COP after Flexi-bar exercise. The support area of the left foot significantly increased (p<0.05), and a significant decrease in mean pressure was observed in the right foot (p<0.05). The total COP path length and area significantly decreased (p<0.05). Furthermore, there was a significant decrease in COP velocity along the X and Y axes (p<0.05). These findings suggest that Flexi-bar exercise can enhance plantar pressure distribution and COP movement patterns, contributing to improved balance ability. Conclusion: Flexi-bar exercise, performed in a standing position, has the potential to improve plantar pressure and COP characteristics. This exercise may serve as a valuable tool for enhancing balance ability. Further research is needed to explore the long-term effects and sustainability of these improvements.

Background: It has been argued that changes in muscle activity in the upper trapezius and serratus anterior may or may not cause shoulder joint pain and dysfunction. Objective: To investigate the effects of active vibration exercise on muscle activity regarding scapular stabilization using a flexi-bar. Design: A randomized controlled trial. Methods: A total of 24 subjects were randomly assigned to a flexi-bar group with active vibration and general stick group with non-active vibration. Both groups performed the same four action programs for 6 weeks, three times a week for 30 minutes at a time. The upper trapezius muscle, middle trapezius muscle, lower trapezius muscle and serratus anterior muscle of the dominant side was measured by electromyography before and after the 6 weeks of exercise. The independent t-test and paired t-test were used to analyze data. Results: There was a significant difference between groups in upper trapezius muscle and serratus anterior muscle activity after exercise (P<.05). Also, there was a significant difference in upper trapezius muscle and serratus anterior muscle activity before and after exercise in the flexi-bar group (P<.05). Conclusion: This study demonstrates that active vibration exercise using a flexi-Bar contribute to reduce the activity of the upper trapezius muscle and promote the activity of the serratus anterior muscle.

Background: Children with cerebral palsy (CP) have impaired postural control, but critically require the control of stability. Consequently, therapeutic interventions for enhancing postural control in children with CP have undergone extensive research. One intervention is sensorimotor training (SMT) using a Flexi-bar, but this has not previously been studied with respect to targeting trunk control in children with CP. Objects: This study was conducted to determine the effect of SMT using a Flexi-bar on postural balance and gait performance in children with CP. Methods: Three children with ambulatory spastic diplegia (SD) participated in the SMT program by using a Flexi-bar for forty minutes per day, three times a week, for six weeks. Outcome variables included the pediatric balance scale (PBS), trunk control movement scale (TCMS), 10 meter walking test (10MWT), and 3-dimensional movement coordination measurement. Results: The SMT provided no statistically significant improvement in PBS, TCMS, 10MWT, or 3-dimensional movement coordination measurement. However, positive changes were observed in individual outcomes, as balance and trunk control movement were improved. Conclusion: SMT using a Flexi-bar may be considered by clinicians as a potential intervention for increasing postural balance and performance in children with SD. Future studies are necessary to confirm the efficacy of Flexi-bar exercise in improving the functional activity of subjects with SD.

Background: Individuals with scapular winging may have proprioceptive dysfunction which is important for motor control and causes shoulder instability. Reduced serratus anterior (SA) and lower trapezius (LT) muscle activity accompanied by over-active upper trapezius (UT), and pectoralis major (PM) may be contributing factors. Flexi-bar (FB) exercise may be used to increase joint position sense (JPS) and alter the target muscle activities. Objects: This study aimed to investigate the immediate effects of flexi-bar exercise prior to knee push-up plus (FPK) versus knee push-up plus (KPP) on JPS and muscle activity of SA, LT, UT, and PM in subjects with scapular winging. Methods: Eighteen subjects with scapular winging were recruited. JPS was investigated at baseline, after KPP and after FPK. Passive and active JPS errors were calculated by isokinetic equipment. Surface electromyography was used to record muscle activities during KPP and FPK. One-way repeated-measures analysis of variance and post hoc analyses were used to analyze the JPS error measured at baseline, after KPP and after FPK. Paired t-tests were used to compare muscle activities between KPP and FPK. Results: Passive JPS error was significantly decreased after KPP (p = 0.005) and after FPK (p = 0.003) compared to the baseline. Active JPS error was also significantly decreased after KPP (p = 0.016) and after FPK (p = 0.012) compared to the baseline. There was no significant difference in the passive and active JPS errors between KPP and FPK. SA activity during FPK was significantly increased (p = 0.024), and LT activity during FPK was significantly increased (p = 0.006). There were no significant differences in the UT and PM activity. Conclusion: FB might be recommended to immediately improve passive and active JPS and to selectively increase SA and LT muscle activities during KPP in individuals with scapular winging.

Purpose: This study aimed to investigate the effect of active vibration exercise on trunk muscle activity, balance, and activities of daily living in patients with chronic stroke. Methods: Twenty-four patients with chronic stroke were randomly assigned to an experimental (n=12) or a control (n=12) group. The experimental group performed an active vibration exercise workout for 20 minutes a day five times a week for 4 weeks using a flexi-bar. Trunk muscle activity was measured using surface electromyography. Balance was measured using the Berg balance scale. Activities of daily living were measured using the functional independence measure. Results: The intragroup comparison showed significant differences in the rectus abdominis, internal oblique, and external oblique muscle activity values, Berg balance scale score, and functional independence measurement values in the experimental group. The intergroup comparison showed that differences in the rectus abdominis and internal oblique external oblique muscle values, Berg balance scale score, and functional independence measurement value for the experimental group were significantly related to those in the control group. Conclusion: Based on these results, this study proved that the active vibration exercise effectively improved trunk muscle activity, balance, and activities of daily living in patients with chronic stroke.
