This study examined the effects of trunk stabilization exercise on balance and trunk control in children with spastic diplegia. Four children with ambulatory spastic diplegia participated in the trunk stabilization exercise program using a Both Sides Utilized (BOSU) ball, 30 minutes a day, two times a week for eight weeks. Outcome variables included the pediatric balance scale, trunk control movement scale and multifidus thickness using ultrasound image. After trunk stabilization exercise, there was statistically no significant improvement in pediatric balance scale, trunk control movement scale and multifidus thickness. However, individual outcomes were observed with some positive changes. Balance, trunk control movement, and thickness of multifidus were found to be improved. Trunk stabilization exercise using a BOSU ball could improve trunk control and increase the thickness of multifidus in children with spastic diplegia. Further investigation is needed to evaluate subjects according to type of cerebral palsy and to understand the relationship between postural control and gait.

Purpose: This study investigated the influence of muscle activity of the trunk and lower limb during a bridge exercise using a unstable surface and during one-legged bridge hip abduction in healthy adults. Methods: Nineteen healthy participated in this study (12 males and 7 females, aged $29.0{\pm}5.0$). The participants were instructed to perform the bridge exercises under six different conditions. Trunk and lower limb muscle activation, such as the erector spinae (ES), gluteus maximus (GM), external oblique (EO), and internal oblique (IO), was measured using surface electromyography. The six different bridge exercise conditions were conducted randomly. Data analysis was performed by using the mean scores after three trials of each condition. Results: On the ipsilateral side, muscle activity of the IO, EO, and ES during the hip abduction condition (Single-legged hip abduction bridge, Bridge with use of a ball and single-leg hip abduction, Bridge with use of a sling and single-leg hip abduction) was significantly higher than those during Unstable surface (Bridge with use of a ball, Bridge with use of a sling) and General bridging exercise (p<0.05). In the contralateral side, activities of the GM and EO during Single-legged hip abduction bridge, Bridge with use of a ball and single-leg hip abduction and Bridge with use of a sling and single-leg hip abduction was significantly higher than that during Bridge with use of a ball, Bridge with use of a sling and General bridging exercise (p<0.05). Conclusion: This study demonstrated that performing a bridge exercise with use of a sling and single-leg hip abduction had an effect on trunk and gluteal muscle activation. The findings of this study suggest that this training method can be clinically effective for unilateral training and for patients with hemiplegia.

PURPOSE: Bridge exercises are broadly used to develop trunk co-activation patterns that promote spine stability. This study was to analyze the trunk muscle activity during bridge exercise with various shoulder support surface(stable, sling, Swiss ball). METHODS: The subjects were 20 healthy subjects in their twenties. Subjects were performed bridge exercise on 4 different shoulder support surfaces using stable and labile instruments. 1) Bridge exercise on a stable surface. 2) Bridge exercise with their shoulder on a stable bench. 3) Bridge exercise with their shoulder on a sling. 4) Bridge exercise with their shoulder on a Swiss ball. Rectus abdominis, erector spinae, internal oblique, external oblique muscle activities were measured using electromyography. RESULTS: There were significant differences in RA, EO muscles between performing each of the 4 exercises(p<.05). RA and EO was recorded the highest activity during the bridge exercise with their shoulder on a sling. The lowest activity was recorded during conventional supine bridge on a stable surface. There were no differences found for the EO/RA and IO/RA ratio. The EO/RA and IO/RA ratio was the highest in the bridge exercise with their shoulders resting on a stable bench. CONCLUSION: These findings suggest that change of shoulder support surface during bridge exercise may be useful for enhancing the trunk stability.

The purpose of this study is to identify the effects of two trunk stability exercise types on the gait factors of stroke patients. We randomly divided 24 old elderly patients with hemiplegia, who were hospitalized due to stroke, into a two groups, each with its own six-week exercise program: one that used of a dynamic trunk stability exercise using with physio-balls(n=12) and a group of one that used a static trunk stability exercise using on mats(n=12). After measuring the participants gait ability a sin a pre-test, we again measured their ability again as in a posttest after two-for both types of six-week exercise programs for each group. The analysis of the data analysis showed that both ball and mat exercise programs significantly improved the participants' gait velocity and stride length; cadence, however, was significantly changed only by the ball exercise program. In conclusion, both types of trunk stability exercise may be useful in improving the gait ability of stroke patients, and, in particular, the former can be used as an exercise method that effectively significantly affects more various other gait factors.

Background: The purpose of this study was to investigate the effect of various relaxation techniques on various dysfunction problems caused by shortening of the sagittal muscles. Method: The subjects were 44(18 males, 26 females). The subjects were composed of 3 groups. The experimental group consisted of 14 patients with proprioceptive neuromuscular facilitation stretching (PNF) technique, control group A 15 patients with self myofacial release (SMR) ball exercise, and control group B with 15 patients with Sling exercise. After 3 weeks of relaxation on the hamstring muscle, the length of the hamstring muscle before and after the intervention was compared. Results: The results of relaxation exercise of the snake muscles applied to passive PNF group, SMR ball group, and Sling relaxation group are as follows. 1. In the passive PNF group, the muscle length of the hamstring muscle was significantly increased after the intervention. 2. The muscle length of the hamstring muscle was significantly increased after the intervention in the SMR ball group. 3. Sling relaxation group significantly increased the muscle length of the hamstring muscle after sling exercise intervention. 4. Passive PNF group showed the greatest change in muscle length before and after intervention than SMR ball group and Sling relaxation group. Conclusion: Passive PNF relaxation therapy, SMR ball relaxation therapy, and Sling relaxation therapy applied to the hamstring muscle were effective in increasing muscle length of the hamstring muscle. PNF relaxation therapy showed the most significant effect after 3 weeks intervention.

PURPOSE: In this study, we sought to investigate the effect of conservative ankle strengthening exercise programs using a Bosu® ball or taping, on the hallux valgus angle and the pain of hallux valgus patients in their 20s. METHODS: The hallux valgus angle, balance, and pain after measuring the hallux valgus were measured to select suitable subjects. In the ankle strengthening exercise group (ASG) an ankle strengthening exercise program using a Bosu® ball was performed for two sessions weekly for four weeks and the taping group (TG) was given Kinesiotaping® for two sessions weekly, two days per session, for four weeks. Before and after the experiment, a footprint was used to examine the changes in the hallux valgus angle and the visual analog scale (VAS) was used to measure pain. RESULTS: An evaluation of the post-experiment changes in the hallux valgus angle and pain showed statistically significant improvement in both groups. There was no statistically significant improvement between groups. CONCLUSION: These results show that both ankle strengthening exercises and Kinesiotaping® have a positive effect on the hallux valgus angle and pain.

Background: Bridging exercises are used to enhance the functional stability of the lumbopelvic region in clinical settings. Although most of the studies on bridging exercises have compared the complete activation of the trunk muscles, some recent studies have examined the functional stability of the trunk and the lumbopelvic region and assessed the appropriate recruitment of the local and global muscles during different task levels. Objects: The purpose of this study was to investigate the changes in muscle thickness in the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles during a common bridging exercise on an unstable surface and to determine whether these changes differ based on the surface used. Methods: Twenty-five healthy young adults (8 males, 17 females) were recruited. The subjects were randomly assigned to either the exercise progression with a sling bridge group or the ball bridging exercise progression group, each with three stages of increasing difficulty. Each position was measured three times with an ultrasonic diagnostic imaging system, and the mean values were recorded for analysis. Results: No significant differences were observed between the TrA, IO, or EO muscle thickness ratios between the sling and ball exercise groups (p > 0.05). There were also no significant differences in the EO muscle thickness ratios between the tasks irrespective of whether the sling or ball was used. However, the TrA and IO thickness ratios in both groups were significantly greater during stages 2 and 3 compared to stage 1. Conclusion: The results suggest that the use of slings and balls during bridging exercises is effective in activating the deep abdominal muscles.

PURPOSE: This study examined the effects of a horse riding simulator, gym ball, and McKenzie exercises on back pain and static balance. METHODS: Among 30 participants with chronic back pain and more than 5 points of ODI, 28 participants were selected. Groups of performing either horse riding, gym ball, or McKenzie were chosen randomly to work out two times a week for six weeks. The static balance was measured using a gym plate and the degree of pain was measured by the VAS and K-ODI. RESULTS: When each exercise was applied to back pain patients, the VAS was changed in all three groups but only in the gym-ball exercise group. The K-ODI varied in all three groups but not in the gym-ball exercise group, In the anterior - posterior static balance, all three groups showed changes, but only the riding exercise group was not significant. In the left-right static balance, all three groups were significant. CONCLUSION: This study showed that six-week exercise for back pain patients was effective in improving back pain and balance ability. Continuous exercise minimizes the risk of recurrence and is effective in preventing and treating back pain.
