Background: The purpose of this study was to investigate the immediate effects of mulligan's straight leg raise with traction technique on angle of passive straight leg raise and length of hamstring muscle in patients with low back and radiate pain. Methods: Thirty one subjects participated in this study. The subjects were assigned to either the low back pain group (n=17) or the radiate pain group (n=14). Subjects in both groups received 3 times mulligan's straight leg raise with traction. All subjects were examined for the range of motion of lower extremity. The range of motion of lower extremity was composed of angle on straight leg raise and 90-90 straight leg raise. The range of motion of lower extremity was measured using a goniometer. Results: After 3 times of mulligan's straight leg raise with traction, significant improvements on the angle of straight leg raise and 90-90 straight leg raise were observed in the both groups (p<.05). However, there are no significant difference was observed between groups. Conclusion: These results suggest that mulligan's straight leg raise with traction provides an immediately effective in range of motion of lower extremity in patients with low back pain as well as radiate pain. Although more research is required on the effects of long-term mulligan's straight leg raise with traction on range of motion of lower extremity, our results can be useful to establish the standard parameters for range of motion of lower extremity in the clinical setting.

Background: There is still controversy as to whether hip external rotation and dorsiflexion selectively activate the vastus medialis obliquus (VMO) during straight leg raise exercise. Due to the anatomical characteristics, hip adduction must be preceded to activate the VMO. In this study, the activities of the rectus femoris (RF), vastus lateralis (VL), VMO were measured by adding the hip adduction movement to the straight leg raise exercise with hip 45° external rotation and straight leg raise exercise with hip 45° external rotation and dorsiflexion. Through this, we want to find out whether the VMO is selectively activated. Methods: Thirteen healthy participants performed straight leg raise exercise with hip 45° external rotation, straight leg raise exercise with hip 45° external rotation and dorsiflexion, straight leg raise exercise with hip 45° external rotation and adduction, straight leg raise exercise with hip 45° external rotation and adduction and dorsiflexion was randomly performed. Through this, EMG data of the RF, VL, VMO were collected. Results: During the straight leg raise exercise, hip adduction increased the activity of the VMO and VL, no significant difference was found(p>.05). However, in the VMO/VL ratio, straight leg raise exercise with hip 45° external rotation and adduction and dorsiflexion activated the VMO and the VL at a ratio of about 1:1, It showed a significantly higher rate than straight leg raise exercise with hip 45° external rotation(p<.05). Conclusion: During the straight leg raise exercise, hip adduction is considered to be an important movement that can selectively induce the activity of the VMO. Therefore, follow-up studies on this should be conducted.

Background: The purpose of this study was to investigate the effects of Mulligan's straight leg raise with traction technique and hold-relax technique on flexibility of hamstring in people with shortened hamstring. Methods: Thirty two subjects participated in this study. The subjects were assigned to either the Mulligan's straight leg raise with traction technique group (n=16) or the hold-relax technique group (n=16). 90-90 straight leg raise test was performed for evaluation of hamstring shortening at initial time of study. After intervention, immediate effect (immediately after intervention) and lasted effect (60 min after intervention) were assessed. Results: In the both Mulligan's straight leg raise with traction technique and hold-relax technique groups, significant improvements on flexibility of hamstring was observed in immediately and 60 minute after intervention (p<.05). However, there are no significant difference was observed between groups (p>.05). Conclusion: In the results of this study, both Mulligan's straight leg raise with traction technique and hold-relax technique show immediately and 60 minute after evaluation effectiveness in flexibility of hamstring of people with shortened hamstring. In addition, although the difference is not statistically significant, Mulligan's straight leg raise with traction technique was more increased average extension angle of knee joint at 90-90 straight leg raise test than the hold-relax technique.

Purpose: The purpose of this study was to investigate the effectiveness of the elastic compression stockings and Kinesio taping on muscle activity and mechanical properties in healthy women during the heel raise exercise that causes muscle fatigue. Methods: Participants were divided into the elastic compression stockings group (ESG, n=8), Kinesio taping group (KTG, n=8), and control group (CG, n=8). All participants performed the heel raise exercise to cause muscle fatigue. Muscle activity, stiffness, and the muscle tone of the gastrocnemius and tibialis anterior were measured before and after the heel raise exercise. Results: In the gastrocnemius, muscle activity was significantly increased after the heel raise exercise in both the ESG and KTG (p<0.05). There was a significant difference in the change in the gastrocnemius muscle activity between the groups (p<0.05). Post hoc analysis showed that the ESG exhibited a significantly greater change in gastrocnemius muscle activity than the CG (p<0.05). The muscle stiffness of the gastrocnemius was significantly decreased after the heel raise exercise in the ESG (p<0.05). The muscle tone of the gastrocnemius was significantly increased after the heel raise exercise in the control group (p<0.05). There were no significant differences in the change in the gastrocnemius stiffness and muscle tone between the groups (p>0.05). In the tibialis anterior, there were no significant differences in muscle activity, stiffness, and muscle tone between and within the groups (p>0.05). Conclusion: Our findings suggest that the use of elastic compression stockings and Kinesio taping during the heel raise exercise are beneficial and delay muscle fatigue in the gastrocnemius.

Purpose: This study examined the effects of heel raise exercises combined with neuromuscular electrical stimulation (NMES) on the muscle strength and postural control ability of subjects with functional ankle instability (FAI). Methods: Twenty-two subjects with FAI participated in this study. They were assigned randomly to two groups: 11 each in the NMES and the sham-NMES groups. Heel raise exercise was applied, and NMES electrodes were attached to the peroneus longus muscles. The NMES group applied NMES during the heel raise exercise. NMES was applied for 20 minutes during the heel raise exercise. The heel raise exercise was performed four times a week for five weeks. The muscle strength and balance error scoring system (BESS) were measured before and after the intervention. Results: A comparison of before and after the intervention within the groups revealed improved muscle strength in the NMES and Sham-NMES groups, but the BESS was improved under all conditions only in the NMES group. The Sham-NMES group showed no improvement in the unstable support surface. Furthermore, when comparing the amount of change before and after the intervention between the groups, there were significant differences in the total score and unstable support in the BESS and muscle strength. Conclusion: NMES had a positive effect on the functional activities of the functional ankle instability subjects, such as balancing on an unstable support surface during postural control and increasing muscle strength.

Purpose: The purpose of this study was to investigate the effects of heel-raise-lower with Kinesio Taping (HKT) on spasticity and balance ability in patients with chronic strokes. Methods: The participants were divided randomly into the HKT group and heel-raise-lower with sham (control group), with 38 participants assigned to each group. Both groups received heel-raise-lower lifting 100 times, 5 times/week for 4 weeks. The HKT group applied Kinesio Taping to the calf muscles. The control group applied Kinesio Taping transversely to the ankle joint and tibialis anterior muscle. The composite spasticity score was used to evaluate the ankle plantar flexors. The center of pressure with the eyes open and closed and limited stability was measured using BioRescue equipment. Both groups evaluated spasticity and balance ability before the experiment and after 4 weeks. Statistical methods before and after working around spasticity and balance ability were independent t-tests. Results: After training, spasticity showed significant improvement in the HKT group and in the control group (p < 0.05). Similarly, balance ability was significantly more improved in the HKT group after 4 weeks of training compared to the control group (p < 0.05). Conclusion: We confirmed the effects of heel-raise-lower with Kinesio Taping (HKT) on spasticity and balance ability in patients with chronic strokes.

Objective: This study aimed to analyze the effects of consecutive whole body vibration through heel raise posture on the center of pressure and electromyography of anterior tibial muscle, lateral gastrocnemius and soleus muscles during single-leg stance. Method: The subjects of this study included 30 healthy males in their 20's, with the following inclusion criteria: no history of orthopaedic medical history, no participation in regular exercises, no history of whole body vibration exercise, and right leg being the dominant leg. The experimental procedure involved pretreatment measurement of eye open single-leg stance, application of whole body vibration for 30 seconds, post-treatment measurement (3 measurements in total). Static and dynamic movements have been measured over 2 separate experiments, with 72 hours gap between the experiments. Static movement involved maintaining single-leg heel raise posture for 30 seconds while applying whole body vibration, and dynamic movement involved heel raise (15 repetitions over 30 seconds) while applying whole body vibration. The strength of applied whole body vibration was 35 Hz frequency and 2~4 mm amplitude. Results: As the single-leg posture after static heel raise posture, mediolateral velocity of the center of pressure at post 2 and post 3 were significantly reduced compared to the pre-treatment measurement. In addition, the percentage for reference voluntary contraction in anterior tibial muscle and soleus and median frequency at anterior tibial muscle and lateral gastrocnemius muscle at post 3 were significantly decreased compared to the pre-treatment value. As the single-leg posture after dynamic heel raise posture, the mediolateral 95% edge frequency of the center of pressure and median frequency at anterior tibial muscle, lateral gastrocnemius muscle, and soleus muscle at post 3 were significantly reduced compared to the pre-treatment value. Conclusion: Acute whole body vibration via static and dynamic heel raise posture have positive effect on mediolateral posture control during single-leg stance.

Objectives : Radix Bupleuri is from the dried root of the herb of the Perennial herbaceous plant, Bulpleurum falcatum L. or Bulpleurum chinense DC. or Bulpleurum. scorzonerifolium Willd., family Umbelliferae. Medicinal Properties are bitter and pungent in flavor, slightly cold in nature and attributed to the liver and gallbladder meridians. Actions in modern Materia Medica are regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking. The ‘uplift yang-qi to raise sinking’ efficacy, out of three efficacies (regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking), has been disputed in the medical profession for a long period. Hereupon, this study ascertained the reason why it has been disputed. Methods : With respect to this medicinal herb, the efficacies of regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking were described as to what was written in ‘Shen Nong's Herbal’ from Chin and Han dynasties until Jin and Yuan dynasties. Results : The beginning of Jin and Yuan dynasties, it began to deal with the ‘uplift yang-qi to raise sinking’ efficacy and so it has been carried on modern textbooks and medical books. The reason why it was added is that it was influenced by the theory of ‘Raise Sinking’ advocated by Zhang jieku who lived in the period of Jin and Yuan dynasties. Since then, the properties of ‘Radix Bupleuri’ have been wrongly known to the public. Additionally, ‘Radix Stellariae Seu Gypsophilae’, which was begun to be introduced from the Four Cities since the Five Dynasties, has been combined with the best stuffs of ‘Radix Bupleuri’ produced from Yin Zhou. Consequently, its original properties were remarkably disordered. Likewise, respective medical schools’ theories were changed by the influence of ‘Bulpleurum. scorzonerifolium Willd’ begun to be used since Tang dynasty. Conclusion : it is considered that the current ‘Raise Sinking’ efficacy of Radix Bupleuri is unreasonable to be applied to the efficacy of the whole Radix Bupleuri because it is limited to certain species.
