This study planed to analyze durability of effect and result that the Medx and Sling exercise gets to the strength of lumbar extensors. 15 patients who had enforce the minimal invasive lumbar surgery were executed 3 times per week for 8 weeks. The purpose of this study was to identify the influence of the mixed exercises of the Medx and Sling program on lumbar trunk muscles and to present basic data for the proper exercise prescription for lumbar patients. The results were as follows: 1) Left: Patients by lumbar hernia operation of trunk muscle strength by Sling-exercise: 0, 45, 90, 135, 180 (degree) treatment periods (P<0.05). 2) Right: Patients by lumbar hernia operation of trunk muscle strength by Sling-Exercise: 0, 45, 90, 135, 180 (degree) treatment periods (P<0.05). Medx treatment, a muscle strengthening lumbar extension exercise program, was now being used at local hospitals. In addition, Sling exercise, which is designed to develop lumbar muscle by way of reducing gravity in a new way so that it can accelerate the growth of muscles and ligaments in-depth in the patients, also has begun to be introduced gradually. In this study, therefore, the new mixed program (Sling and Medx training)can used as an exercise program that can reduce pain and increase lumbar muscles, not only for disk disease patients but also for all those who have undergone surgery or who haven't undergone surgery, who have chronic pain, and it also can be utilized as basic data for the new method of exercise.

Objective: The purpose of this study was to evaluate the effects of closed chain lower limb exercise with abdominal breathing exercise on stroke patients and their effects on trunk control ability and balance. Method: The subjects were 40 stroke patients, 19 patients in the experimental group and 18 patients in the control group. The period was 5 weeks, 5 times a week, 30 minutes per session. The experimental group was subjected to a closed chain lower limb exercise with abdominal breathing exercise and the control group was subjected to a closed chain lower limb exercise. The posture assessment scale for stroke(PASS), trunk impairment scale(TIS) were used for trunk adjustment ability, and the balance ability was measured as center of pressure(COP) and limit of stability(LOS). Results: Results of this study showed that the PASS and TIS test significantly increased the experimental group compared to the control group. As a result of comparing the changes of pre and post intervention intervals between the two groups, the TIS test was significantly lower in the experimental group than in the control group, but the LOS test was not significantly increased in the experimental group. Conclusion: Closed chain lower limb exercise with abdominal breathing exercise showed a significant improvement in the trunk control and balance ability of the stroke patients compared to the closed chain lower limb exercise without the abdominal breathing exercise.

Objective: The purpose of this study was to investigate muscle activation according to the four strap lengths in the TRX plank exercise to provide scientific and accurate data on effective training methods. Method: Twenty healthy men who had at least 6 months of weight training experience and could fully adjusted plank exercise, were participate in this study (age: 25.2 ± 3.7 yrs., height: 174.2 ± 3.9 cm., weight: 71.2 ± 9 kg). To pursue the study purpose, surface electrodes were attached to trunk muscles (pectoralis major, rectus abdominis, external oblique, internal oblique, erector spinae, latissimus dorsi) and lower extramity muscles (gluteus maximus, rectus femoris, gastrocnemius), and the muscle activity was measured using 11-channel electromyography equipment. In order to verify the muscle activation according to the four strap lengths during TRX plank exercise, an one-way ANOVA with repeated measure was used with statistical significance level set at as α=.05. Results: First, there were statistically significant differences in pectoralis major, rectus abdominis, external oblique, internal oblique, and erector spinae among TRX strap lengths. Second, there were statistically significant differences in gluteus maximus, rectus femoris, and gastrocnemius among TRX strap lengths. Third, even though no statistically significant difference found in latissimus dorsi, but increased muscle activation tendency was showed as the length of the strap increased. Conclusion: From the results of this study, it may be possible that TRX exercise prevent injuries and improve lower extremity muscle as well as trunk muscles by setting appropriate length of strap.

Overweight and abdominal obesity caused by sedentary lifestyle may induce deconditioned and atrophied extensor musculature of the lumbar spine and be a potential risk factor for low back pain (LBP). Therefore, this study was conducted to evaluate the validity of high intensity circuit training (HICT) on weight loss and subsequent alleviation of spine curvature (SC) and visual analog scale (VAS) among middle aged men with abdominal obesity. The training program (1 exercise session for 30 minutes, three times a week for 12 weeks) consisted of 12 different functional exercises based on core strengthening multiple joint circuit training. Portions of the obesity index related to body composition were positively changed, which improved the angles of thoracic kyposis and lumbar lordosis, which appeared to effectively reduce lower back pain. Taken together, HICT specifically designed for LBP effectively decreased obesity related body composition and was superior to other treatments for decreasing aggravation of the spine curvature and LBP caused by abdominal obesity; however, weight loss should be the primary treatment target for LBP patients.

The aim of this study is to compare measurements of abdominal muscle thickness using ultrasonography imaging (USI) to those using a special transducer head device, during five different trunk stabilization exercises, ultimately to determine which exercise led to the greatest muscle thickness. Thirty eight healthy subjects participated in this cross-sectional study. The five types of trunk stabilization - i.e., a sit-up on the supine, an upper and lower extremity raise with quadruped on the prone, a leg raise in sitting on the ball, trunk rolling on the ball, and balance using sling on the prone position - were each performed with an abdominal draw. The thickness of the abdominal muscle - including the transverse abdominal (TrA), internal oblique (IO), and external oblique (EO) - was measured by USI with a special transducer head device, at rest and then at contraction in each position. Data were analyzed using one-way repeated ANOVA with the level of significance set at ${\alpha}$=.05. The results were as follows: 1) the TrA thickness was statistically significant (p<.05), whereas the IO and EO thicknesses were not (p>.05); 2) among the five types of trunk stabilization, TrA thickness significantly increased with the balance using a sling in the prone position, (p<.05), whereas no significant difference was noted for the four types of trunk stabilization (p>.05); 3) reliability data showed that there was a high degree of consistency among the measurements taken using the special transducer head device (ICC=.92). In conclusion, the balance using a sling in the prone position was more effective than any of the four other types of trunk stabilization in increasing TrA thickness in healthy subjects.

The aim of this study was to investigate effects of reaching distance on movement time and trunk kinematics in hemiplegic patients. Eight hemiplegic patients participated in this study. The independent variables were side (sound side vs. affected side) and target distance (70%, 90%, 110%, and 130% of upper limb). The dependent variables were movement time measured by pressure switch and trunk kinematics measured by motion analysis device. Two-way analysis of variance with repeated measures was used with Bonferroni post-hoc test. (1) There were significant main effects in side and reaching distance for movement time (p=.01, p=.02). Post-hoc test revealed that there was a significant difference between 110% and 130% of reaching distance (p=.01). (2) There was a significant main effect in side and reaching distance for trunk flexion (p=.01, p=.00). Post-hoc test revealed that there were significant differences in all pair-wise reaching distance comparison. (3) There was a significant side by target distance interaction for trunk rotation (p=.04). There was a significant main effect in target distance (p=.00). Post-hoc test revealed that there were significant differences between 70% and 110%, 70% and 130%, 90% and 110%, 90% and 130% of target distance. It was known that trunk flexion is used more than trunk rotation during reaching task in hemiplegic patients from the findings of this study. It is also recommended that reaching training is performed with limiting trunk movement within 90% of target distance whereas reaching training is performed incorporating with trunk movement beyond 90% of target distance in patients with hemiplegia.

Purpose: The purpose of this study is to provide an efficient and scientific basis for muscle activity (%MVIC) of RA, EO, VL, HS muscles and balance in soccer players through dynamic lumbar stability exercise and static lumbar stability exercise. Methods: This study included 23 soccer players belonging to D University of J province who attended the program for 30 minutes at a time and three times a week for 4 weeks. Of these 13 attended the dynamic lumbar stability exercise (DLSE) program and 10 the static lumbar stability exercise (SLSE) program. The differences between the effects of the dynamic lumbar stability exercise program and static lumbar stability exercise program were analyzed. Results: To increase muscle activity (%MVIC) and balance (WPL), the dynamic lumbar stability exercise program was more effective than was the static lumbar stability exercise program. 1) The %MVIC of trunk muscle (RA &EO) and lower extremitys muscle (VL & HS) increased from before training to after training in the case of the participants who performed the dynamic lumbar stability exercise. 2) The whole path length (WPL) decreased from before the training to after the training. The 2 groups significantly differed in this regard. Conclusion: Dynamic lumbar stability exercise program helps to improve the balancing ability and muscle activity in a soccer players who requires both muscle activity and balance than does any other players.

PURPOSE: The main objective of this study is observing the effects of the functional postural trunk exercise (FPTE) on deep cranio-cervical flexor (CCF) muscle endurance applied on neck pain patients suffering from the acute whiplash-association disorder (WAD). METHODS: The study was tested with 47 patients with neck pain. All patients were equally treated with the ordinary therapy, only experimental group (n=23) was treated with FPTE: assumption of an upright lumbo-pelvic and spinal postural position, adding a neck lengthening manoeuvre in addition. Patients attended physical therapy for 3 times a week, for 4 weeks. Visual analogue scale (VAS) for pain, neck disability index (NDI), range of motion (ROM), were recorded both before and after the intervention. Also muscle activity in the CCF test was employed to analyze the changes between before and after. RESULT: After 4 weeks of training intervention, a remarkable increase in muscle endurance, rotation, extension ROM (p<.05) and decrease in pain and NDI (p<.05) in both groups. Further, the differences between groups were muscle endurance (F=60.350, p<.01), pain, and the left rotation ROM (p<.05). CONCLUSION: From the results, the experimental group had significant the increase in muscle endurance, and the significant decrease in pain. Whilst further research in this category is necessary, these observations suggest that applying exercise in early diagnosis can be of help to treat the neck pain patients suffering from the WAD.

The purpose of this study was to investigate the effect of dual task training on postural stability and balance in chronic stroke patients. A total of 25 ambulatory hemiplegic stroke patients were recruited into this study and randomly assigned into two groups, the dual task training group (n=13) and control group (n=12). Both groups received general physical therapy for 30 minutes a day, 5 days a week during 6 weeks. In addition, dual task training group received dual task training programs for 50 minutes a day, 3 days a week during 6 weeks. The scores of Trunk Impairment Scale (TIS), Postural Assessment Scale for Stroke (PASS) and postural sway with eye opened and eye closed on the Force Plate were assessed before and after intervention. Postural stability and balance significantly improved after training in the dual task training group(p<0.05). The result suggests that dual task training is feasible and suitable for individual with chronic stroke.

Purpose: The aim of this study was to evaluate the effect of lumbar stabilization exercise on an unstable surface on trunk posture and static standing balance ability in patients with scoliosis. Methods: Subjects included 18 patients who showed symptom of scoliosis. Patients were divided into two experimental groups, one using an unstable surface and one using a fixed surface, and the patients were required to perform a lumbar stabilization exercise a total of 12 times for 60 minutes per session, three times per week for a period of four weeks, with a six-months follow-up period. Results: A significant reduction was observed in the group that performed the lumbar stabilization exercise on an unstable surface (p<0.05). A significant decrease in both the condition of closed eyes or open eyes in the left and right directions was observed in the group that performed the lumbar stabilization exercise on an unstable surface (p<0.05). After six months, results of comparison of the length of both sides of the trunk showed a significantl decrease in the group performing lumbar stabilization exercises on an unstable surface. Conclusion: Lumbar stabilization exercise on an unstable surface improved the trunk posture of patients with scoliosis symmetrically, and static balance ability in a standing posture showed improvement. In the future, lumbar stabilization exercise on an unstable surface may be used as an exercise for posture correction and balance increase for patients with scoliosis.
