The aim of this study was to compare the effect of a horseback riding simulator, Slings and Kendall Exercise on a cranio-vertebral angle and the neck pain of the Forward Head Posture. This study included 30 young people with forward head posture. They were randomly divided into three groups. Each group performed the exercises for six weeks three times a week from September 2018 to November 2018. The variations of cranio-vertebral angle and neck pain were analyzed using paired t-tests and a one-way ANOVA test. The results of the study are as follows. Three groups showed significant variations of cranio-vertebral angle and neck pain (p < 0.05). But comparison of cranio-vertebral angle and neck pain between the groups showed no significant difference (p > 0.05). This study found that each exercise group for forward head posture was effective for inducing normal cervical alignment and neck pain relief. Therefore, various exercises can improve the forward head posture.

PURPOSE: The purpose of this study was to investigate the effect of short-term lumbar stabilization exercise to patients suffering from chronic low back pain(CLBP) on the strength of their lumbar flexor and extensor and the postural balance of them and to suggest effective treatment duration for them. METHODS: Study subjects were 20 patients with CLBP who's been reported the pain for more than 12 weeks. For these subjects, muscle strength of both extensor and flexor of lumbar and the balancing ability were measured before and after the intervention. Lumbar stabilization exercise was composed of matt, ball and sling exercise. The intervention was applied for total 12 sessions for 4 weeks (3 times a week) and each session was for 40 minutes. RESULT: For muscle strength of both extensor and flexor of lumbar, there was significant differences after the application of lumbar stabilization exercise(p<.05). For balancing ability, stabilization shows significant differences in all of the positions except PC(eyes closed on pillows)(p<.05). Distribution of weight shows no significant differences but it was generally distributed within normal range after the exercise and Fall index shows significant differences between before and after the exercise(p<.05). CONCLUSION: These results could have positive effect on deciding different periods of therapeutic intervention.

Purpose: The aim of this study was to determine the change of static and dynamic foot pressure on trunk stabilization exercise in children with spastic diplegic cerebral palsy. Methods: This study examined five male children participants ages 10~14 years old with spastic diplegic cerebral palsy. All subjects participated in a 6-week sling exercise program for trunk stabilization; the exercise was performed three times per week and each session lasted 50 minutes. The subjects were measured for static and dynamic foot pressure and bilateral symmetry of both feet before and after the trunk stabilization exercise. Results: The static foot pressure increased significantly before and after the trunk stabilization exercise (left foot: before $0.41{\pm}0.02%BW/cm^2$ after $0.79{\pm}0.02%BW/cm^2$, right foot: before $0.14{\pm}0.03%BW/cm^2$, after $0.43{\pm}0.44%BW/cm^2$) (p<0.05) and bilateral symmetry of both feet increased (before $0.27{\pm}0.18%BW/cm^2$, after $0.37{\pm}0.05%BW/cm^2$) with more weight shift on left foot than right foot, but was not statistically significant (p>0.05). The dynamic foot pressure increased (left foot: before $2.58{\pm}0.44%BW/cm^2$, after $3.40{\pm}0.31%BW/cm^2$, right foot: before $2.75{\pm}0.19%BW/cm^2$, after $3.26{\pm}0.18%BW/cm^2$) with more weight shift on right foot than left foot, but was not statistically significant (p>0.05), and bilateral symmetry of both feet decreased (before $0.31{\pm}0.36%BW/cm^2$, after $0.13{\pm}0.20%BW/cm^2$) (p<0.05). Conclusion: The findings of this study indicated that the trunk stabilization exercise has a positive impact on static and dynamic foot pressure in children with spastic diplegic cerebral palsy.

Purpose: This study aimed to compare the relative muscle activity on the erector spinae, gluteus maximus, and hamstring, using a non-visual feedback bridge exercise and a visual feedback bridge exercise with a tension sensor and clinometer. Methods: Twenty-two healthy subjects participated in this study. The study subjects performed bridge exercises without visual feedback, bridge exercises using a tension sensor, and bridge exercises using an inclinometer in the supine position, and the muscle activity of the left and right erector spinae, gluteus maximus, and hamstring muscles was measured while maintaining isometric contraction during the bridge movement. Muscle activity was measured by using surface an electromyography equipment. To standardize the measured action potential of each muscle, the maximum voluntary isometric contraction was measured. The bridge exercise was repeated 3 times for 5s each. Using repeated analysis of variance, we compared the significant difference in EMG activity for each muscle between the three experiments, and all statistical processing was performed using SPSS version 26. The statistical significance level was set at α = 0.05. Results: During bridging exercises, the asymmetry of the muscle activity of the erector spinae and gluteus maximus during visual feedback guiding was lower than that during no visual feedback. However, there was no significant difference. Moreover, the asymmetry of the muscle activity of the hamstring muscles was significantly lower during tension sensor visual feedback than that during no visual feedback (p<0.05). Conclusion: These findings suggest that bridge exercise with visual feedback using a tension sensor and an inclinometer is effective in inducing symmetrical movement. When it is necessary to symmetrically adjust the weight load of both feet during the bridge exercise, it is effective to apply visual feedback using a tension sensor.

PURPOSE: This study examined the effects of the resistance levels on the muscle activities around the hip and spine during bridge exercise with hip abduction resistance in patients with chronic back pain. METHODS: A cross-over study design was used. Twenty subjects with low back pain were enrolled in this study. The subjects performed bridge exercises with hip abduction resistances (20 mmHg, 40 mmHg, and 60 mmHg). A Narrow Sling was used to provide resistance. Surface electromyography was used to measure the activity of the erector spinae, biceps femoris, gluteus maximus, and gluteus medius. RESULTS: The muscle activity of the gluteus maximus and gluteus medius increased significantly with increasing resistance levels. There was a significant difference in the muscle activity of the biceps femoris with a resistance level between 20 mmHg and 40 mmHg, but there was no significant difference in the other resistance levels. There was no significant difference according to resistance level in the erector spinae. The muscle activity ratios of the gluteus medius/erector spinae and gluteus maximus/erector spinae increased significantly with increasing resistance strength. CONCLUSION: The different levels of abduction resistance for hip abduction during bridge exercise will help activate the gluteus maximus selectively in patients with chronic back pain.

Purpose: This study examined the most efficient exercise position to activate the gluteus medius (GM) and tensor fascia latae (TFL) in hip abduction in side-lying (HA-SL), clam in side-lying (CL-SL), and sling bridging in side-lying (SB-SL), which are the most representative GM exercises. Methods: Twenty-four healthy male adults aged from 20 to 40 years, whose body mass index was under 25, participated in this experiment. While all participants conducted three different positions with a counterbalanced manner, such as in AB, CL, and BR, activation of the GM and TFL was measured using 8-channel wireless EMG. Exercise was performed for 10 seconds three times in total with a five minute-break session. Results: Significant differences in GM and TFL activation were observed among the three positions (p<0.05). The highest activation of 60.69 was observed in BR followed in order by 46.03 and 12.92 in HA-SL and CL, respectively. TFL activation in HA-SL was 42.01, followed in order by 35.98 and 14.01 in BR and CL, respectively. On the other hand, there was no significant difference in TFL muscle activation between BR and HA-SL. Conclusion: These findings suggest that both BR and HA-SL in GM can be done selectively. CL has remarkably low muscle activation in GM and TFL, which makes it less valuable in GM and TFL exercise. In conclusion, selective BR and HA-SL exercise should be applied to maximally and effectively activate the GM.

Background: Scapular winging is a rare disorder that is commonly caused by nerve damage of the dorsal scapular nerve, spinal accessory nerve, or the long thoracic nerve. This affects the scapulohumeral rhythm which may cause abnormal kinetic motion of the shoulder. The purpose of this case report is to describe a self-exercise oriented management incorporating shoulder strengthening to reduce symptoms in a shoulder pain patient with winging scapular. Methods: A 45 year old male patient complained of pain in his both shoulders without any trauma. Shoulders were treated with steroid injections for supraspinatus tendonitis, but although pain improved to some extent, pain and disability continued for 3 months. Both shoulders had pain, decreased active range of motions, muscles weakness, and scapular winging. The patient underwent 9 interventional sessions over 3 months and was managed mainly by self-exercise. The intervention method involved push up plus, sling, muscle strengthening, and stabilization exercises. Loads were increased as symptoms improved. Results: Clinical outcomes were measured at every session. Pain in both shoulders reduced to 0 on a numerical pain rate scale by the 4th session, and the active range of motion was fully recovered. During the 9th session, the strength of the serratus anterior had improved from grade P to G on the right side and grade G to N grade on the left. Conclusion: In this case study, the self-exercise program was effective in reducing pain, increasing active range of motion, and improving muscle strength in subjects with scapular winging.

Purpose: The purpose of this study was to investigate the effects of exercise training using biofeedback and constraint-induced movement on the upper extremity function of hemiplegic patients. Method: A non-equivalent pretest-posttest design was used. Study subjects were a conveniently selected group of 40 hemiplegic patients(20 experimental subjects, 20 control subjects) who have been enrolled in two community health centers. After biofeedback training the subjects of experimental group were given constraint-induced movement, involving restraint of unaffected U/E in a sling for about 6 hours in a day over a period of two weeks, while at the same time intensively training the affected U/E. Outcomes were evaluated on the basis of the VIE motor ability(hand function, grip power, pinch power, U/E ROMs), and motor activity(amount, quality). Result: 1. After 2 weeks of treatment, the motor abilities of affected U/E(hand function, grip power, pinch power, ROMs of wrist flexion, elbow flexion and shoulder flexion/extension) were significantly higher in subjects who participated in exercise training than in subjects in the control group with no decrement at 4-week follow-up. However, there was no significant difference in wrist extension between experimental or control group. 2. After 2 weeks of treatment, the amount of use and the quality of motor activity of affected U/E were significantly higher in subjects who participated in exercise training than in subjects in the control group with no decrement at 4-week follow-up. Conclusion: The above results state that exercise training using biofeedback and constraint-induced movement could be an effective intervention for improving U/E function of chronic hemiplegic patients. Long-term studies are needed to determine the lasting effects of constraint-induced movement.

PURPOSE: This study aimed to compare the effects of lumbar stabilization exercise with those of the neurodynamic technique on low back pain in patients with lumbar instability. METHODS: The subjects included those with more than three tests with positive results for lumbar instability and those with a positive sign during the neurodynamic test, all of whom had low back pain. For the lumbar stabilization exercise group (n=15), lumbar stabilization exercise was performed using a sling system, while the neurodynamic technique group (n=15) performed the neurodynamic technique. The intervention was performed 5 days a week for 4 weeks. All measurement of each subject were measure at pre-intervention and post-intervention (after 4 weeks). SPSS/PC ver. 18.0 program was used to compile results. RESULTS: There was no significant difference in general characteristics of subjects between both groups (p>.05). Assessed items included the visual analog scale score (VAS), Korean version of the Oswestry Disability Index (KODI), lumbar instability test positive response counter (LIC) and Fear-Avoidance Beliefs Questionnaire score (FABQ), and a significant reduction was observed post-intervention compared to pre-intervention values in both groups (p<.01). Other assessed items such as trunk flexibility and lumbar extensor endurance and lumbar flexor endurance were significantly increased post-intervention in both groups compared to pre-intervention values (p<.01). There was no significant difference in all parameters between both groups (p>.05). CONCLUSION: Our results indicate that the neurodynamic technique may be useful for improving low back pain in patients with lumbar instability.
