Purpose: This study aimed to adjust the craniovertebral angle and shoulder alignment through shoulder and abdominal stabilization exercises in adults with a forward head posture. Methods: The study participants were 29 adults with a forward head posture, and they were randomly divided into the following groups: 14 participants in a combined exercise group that used shoulder and abdominal stabilization exercises and 15 participants in a shoulder exercise group that used just shoulder stabilization exercises. The participants performed the stabilization exercises for 30 minutes per day, three times a week for five weeks. Results: There were significant differences in the craniovertebral angle after intervention in the shoulder stabilization exercise group (p < 0.05). There were significant differences in the craniovertebral angle and location of the right root of the spine and both inferior angles before and after intervention in the shoulder and abdominal stabilization exercise group (p < 0.05). There was a significant difference in the location of the right root of the spine and the left inferior angle between the groups at the post-test (p < 0.05), and there was a larger change in the shoulder and abdominal stabilization exercise group. Conclusion: There was a significant difference in the craniovertebral angle and a partially significant difference in shoulder alignment before and after intervention in both groups.

The purpose of this study was to analyse the effect of posture correction & stabilization according to horse rider's(n=10) skill levels of novice(0wk), mid-skill(12wk) & skill(24wk) in walk & trot. First, Mean posture of 3 times experiments; Anterior & posterior leaning posture of trunk showed rather unstable according to progress of the stages of TD1, TO, TD2 phase, and also shoulder & elbow angle, which effects to the distance from bit to rein, showed unstable riding posture. There was close relationship between shoulder and elbow Angle in walk and hip, knee & ankle angle in trot. Second, Posture correction & stabilization according to riding skill levels; Anterior & posterior leaning posture of trunk did not show significant difference statistically but showed approaching tendency to trunk's vertical line and showed significant difference(p<.05) according to improvement of skill levels in walk & trot horse riding. Hip angle showed significant difference according to progress of the stages of TD1, TO, TD2 phase(p<.05) and showed tendency maintaining the larger thigh flexion according to improvement of skill levels in walk & trot. Knee angle showed more stable posture by maintaining the larger flexion between thigh and shank according to improvement of skill levels in walk & trot(p<.05). Ankle angle also showed tendency maintaining the larger plantar flexion of foot according to improvement of skill levels in walk & trot. When considering the above, regular horse riding program could be useful in posture correction & stabilization according to improvement of skill levels of novice(0wk), mid-skill(12wk) & skill(24wk) in walk & trot.

Background: The purpose of this study is to analyze the effect of shoulder and neck stabilization exercise using a gym ball for healthy women in their 20s with round shoulder and forward head posture, it is intended to try and find improvement for posture. Methods: The subjects of the study were 25 women who understood the purpose of the research and voluntarily agreed to participate in the experiment. They carried out the shoulder and neck stabilization exercise program using a gym ball, which was conducted for 35 minutes, 3 times a week for 4 weeks. The position of the round shoulder and shoulder bones was measured using an tape measurement and were recorded in both at pre, 2 weeks, and post intervention. The craniovertebral angle (CVA) and craniorotational angle (CRA) was measured using an image J. Results: The round shoulder posture left was statistically significantly different within group (p<.05); however, the round shoulder posture right wasn't statistically significantly different (p>.05). As a result of this contrast, test were significant different in both at pre, 2 weeks and post. The scapular position on the left and right were statistically significantly different within the group (p<.05). As a result of the contrast, test were significant different in both at pre, 2 weeks and post (p<.05). The CVA and CRA on the left and right were statistically significantly different within the group (p<.05). As a result of the contrast, test were significant different in both at pre, 2 weeks and post (p<.05). Conclusion: The gym ball exercises improved the posture of women in their 20s. Therefore, gym ball exercises can help improve the quality of life of those with shoulder and neck pain.

The purpose of this study was to examine the immediate effect of neck stabilization exercise and Swiss ball exercise on the recovery from the fatigue of neck muscles induced. The turtleneck posture was set artificially by using Smartphone with healthy adults. Repetitively measured ANOVA was executed to examine the changes in the muscle fatigue of sternocleidomastoid, upper trapezius, and splenius capitis among three-time intervals (at the time of general resting, work and after intervention) in the three intervention groups (neck stabilization exercise group, Swiss ball exercise group, and ordinary rest group). There were no significant differences in the changes of fatigue of sternocleidomastoid muscle among all three intervention groups at the time of general resting, work and after intervention (p>.05). Although there was no significant difference in the changes in the fatigue of upper trapezius and splenius capitis muscles between the intervention groups at the time of general resting and work (p>.05), there was the significant difference between the three intervention groups at the time of work and after intervention (p>.05). This study suggest that Swiss ball exercise is more effective in reducing the muscular fatigue of the neck and shoulder at a turtleneck posture than neck stabilization exercise.

PURPOSE: This study aimed to compare the effects of manual therapy with stabilization exercises to manual therapy alone, on neck pain and body functions in patients with chronic mechanical neck pain. METHODS: Twenty patients with chronic mechanical neck pain were recruited and randomly allocated into two groups. A control group(n = 10) was given the manual therapy alone and an experimental group(n = 10) was given the manual therapy with stabilization exercises. The intervention was carried out 3 days per week for 4 weeks. The cervical resting pain, the most painful motion pain, craniocervical flexor endurance, forward head posture and neck disability index were used to assess participants at baseline and after 4 weeks. RESULTS: A comparison of the parameters before and after the intervention showed that both groups experienced significant improvements in the resting pain, the most painful motion pain, craniocervical flexor endurance, and forward head posture except for the forward head posture in the control group. A comparison of the parameters between the groups did not show a significant difference. CONCLUSION: The results of this study suggest that the combined intervention of manual therapy with stabilization exercise does not seem to be more effective than manual therapy alone for improving neck pain, craniocervical flexor endurance, forward head posture, and the neck disability index in patients with chronic mechanical neck pain.

Purpose : This study was somatosensory less in patients with idiopathic scoliosis somatosensory input to the lumbar stabilization exercises carried out to determine the most effective treatment method to be stable and unstable in terms of supporting the lumbar stabilization exercises the patient's torso length and postural sway by comparing the distance from a standing position and looked for differences in effect on the balance. Methods : The subjects of the study were 18 patients who showed the symptom of scoliosis. The study classified the patients into two experimental groups, one using an unstable surface and one a fixed surface, and the patients were required to do a lumbar stabilization exercise a total of 12 times for 60 minutes per session, three times a week for four weeks. The study carried out a paired comparison t-test so as to compare differences between measurement values in each experimental group before and after the exercise. Results : Superior iliac spine on the left, there was a significant reduction in the group doing the lumbar stabilization exercise on an unstable surface (p<0.05). Regarding change in sway distance to the left and right directions in the group doing the lumbar stabilization exercise on the unstable surface, there was a significant decrease in both the condition of closed eyes or open eyes (p<0.05). As for change in sway distance in forward-and-backward direction, there was a significant reduction in the condition of either closed eyes or open eyes (p<0.05). Conclusion : The lumbar stabilization exercise on an unstable surface improved the trunk posture of patients with scoliosis symmetrically, and the static balance ability in a standing posture was discovered to be improved. In the future, the lumbar stabilization exercise on an unstable surface may be used as a posture correction and balance increase exercise for patients with scoliosis.

Purpose: This study was to evaluate the effect of cranio-cervical flexion based trunk stabilization exercise on gross motor function and posture alignment change in children with spastic cerebral palsy. Design: Randomized Controlled Trial. Methods: Twenty-six children participated in this study. All subjects were randomly assigned to either the Cranio-Cervical Flexion Based Trunk Stabilization Exercise (CCFTS) group (n=13) or the Trunk Stabilization Exercise (TS) group (n=13). In both groups were trained general physical therapy for 10 minutes, in the CCFTS group was trained cranio-cervical flexion based trunk stabilization exercise for 20 minutes and in the TS group was trained trunk stabilization exercise for 20 minutes. The training was provided 2 times a week during 8 weeks. All subjects were measured with the Gross Motor Function Measure (GMFM) and Cranio-Vertebral Angle (CVA) before and after intervention. Results: The results showed that the CCFTS have increased significantly in GMFM (B, C, D and E-dimension) and CVA, and the TS group have increased significantly in GMFM (B, C D and E-dimension). In particular, the CCFTS group improved significantly than TS group in GMFM (B, C and D-dimension) and CVA. Therefore, the cranio-cervical flexion based trunk stabilization exercise improved gross motor function and posture alignment in children with spastic cerebral palsy. Conclusion: These results suggest that cranio-cervical flexion based trunk stabilization exercise is feasible and suitable for individuals with a spastic cerebral palsy and can be used in addition to conventional physical therapy.

This paper proposes a posture stabilization control algorithm for a wheeled mobile robot using hybrid visual servo control method with a position based and an image based visual servoing (PBVS and IBVS). To overcome chattering phenomena which were shown in the previous researches using a simple switching function based on a threshold, the proposed hybrid visual servo control law introduces the fusion function based on a blending function. Then, the chattering problem and rapid motion of the mobile robot can be eliminated. Also, we consider the nonlinearity of the wheeled mobile robot unlike the previous visual servo control laws using linear control methods to improve the performances of the visual servo control law. The proposed posture stabilization control law using hybrid visual servoing is verified by a theoretical analysis and simulation and experimental results.

PURPOSE: This study examined the effects of the craniovertebral angle, proprioception (joint error test), and the upper trapezius on the muscle tone when comparing cervical stabilization and scapula stabilization exercises and when two exercises were performed together. METHODS: The participants in this study agreed in advance, and this study was carried out by recruiting 27 university students in their twenties with mild frontal posture. The subjects were assigned randomly to three groups that performed cervical stabilization exercises, scapular stabilization exercises, and both cervical and scapular stabilization exercises. One-way repeated ANOVA was used to analyze the evaluation values of the 1^st, 3^rd, and 6^th weeks of exercise intervention within the group, and one-way ANOVA was used to compare the difference in the effects of exercise intervention among the three groups. RESULTS: Proprioception was significantly different in the cervical stabilization exercises (CSE) group and the cervical stabilization exercises + Scapular stabilization exercises (CSE+SSE) groups at three weeks, and there was a significant difference between the scapular stabilization exercises (SSE) group and the CSE+SSE group (p < .05). At six weeks, there was a significant difference between the CSE group and the CSE+SSE group, and there was a significant difference between the SSE group and the CSE+SSE group (p < .05). There was a significant difference between three and six weeks in the CSE group (p < .05). In the SSE group, there was a significant difference between pre and six weeks, and between three and six weeks (p < .05). In the CSE+SSE group, there was a significant difference between pre and three weeks, and between pre and six weeks (p < .05). On the other hand, there were no significant differences between CVA and muscular tone in all three groups (P > .05). CONCLUSION: In all groups, the proprioception (joint error test) showed significant improvement, and the CSE+SSE group showed greater improvement than the other groups. As a result, the appropriate combination of neck stabilization exercise and scapular stabilization exercise effectively improved proprioception in the presence of forward head posture (FHP).
