Purpose : The purpose of this study is to determine the effects of high heeled shoes on the static balance and EMG activity of lower extremity muscles. Methods Twenty subjects were composed of control group(wearing low-heeled shoes) and experimental group(wearing high-heeled shoes). Two groups participated in bearfoot standing and measured static balance and EMG activity of lower extremity muscles. Balance Performance Monitor(BPM) was used to measure the static balance and FlexComp $Infiniti^{TM}$ was used to measure the EMG activity of lower extremity muscles. Results In static balance, sway area and path of experimental group was significantly larger than control group(p<0.05). And sway velocity of experimental group was significantly faster than control group(p<0.05). They means static balance of experimental group was significantly lower than control group(p<0.05). In EMG activity, L5 paraspinalis and biceps femoris of experimental group was significantly more increased than that of control group(p<0.05). Conclusion : The long-time experience in wearing high heeled shoes may have caused change in static balance and EMG activity of lower extremity muscles.

The purpose of this study was to investigate effect of low-dye taping and foot intrinsic muscle strengthening exercise on the muscle activity of the tibialis anterior, calf muscles, and long calf muscles during one-foot standing in subjects with flat feet. The subjects were 16 adults in their 20s with flat feet, and they were divided into low-dye taping (LTG; n=8) and foot intrinsic muscle strengthening exercise (FSG; n=8) groups. Each group underwent the appropriate intervention twice a week for 6 weeks. The muscle activity of the tibialis anterior, long calf muscle, and medial calf muscle was measured. Repeated two-way ANOVA was performed to compare changes in muscle activity before and after the intervention. As a result of muscle activity measurement, LTG significantly decreased between before and after the experiment in all muscles (p<.05). In FSG, only the tibialis anterior significantly decreased between before and after the experiment (p<.05). Therefore, low-dye taping and foot intrinsic muscle strengthening exercises will be helpful for efficient the lower extremity muscle activity of flat foot.

PURPOSE: The objective of this study was to determine the effects of virtual reality training on muscle activation in the elderly. METHODS: The subjects were 32 healthy elderly people aged between 65 and 80, who were divided into the VR(virtual reality) training group(n=17) and the control group(n=15). The Virtual reality training group engaged in a 30-minute exercise session using Wii Fit three times a week for eight weeks. Virtual reality training group used the Ski Slalom, Table tile, Balance bubble programs. low-extremity muscle activation of the two groups were measured before and after the intervention. RESULTS: To investigate the effects of the training on lower-extremity muscle activation, biceps femoris, gastrocnemius, tibialis anterior, vastus lateralis were measured. The results revealed that the activation of gastrocnemius and tibialis anterior significantly increased(p<.05), which indicates virtual reality training is effective in improving the activation of the muscles involved in the movement of the ankle joint. CONCLUSION: Virtual reality training is effective in improving the healthy elderly's activation of the muscles involved in the movement of the ankle joint. Thus, virtual reality training can be proposed as a form of fall prevention exercise for the elderly.

Purpose: this study was to examine the differences of the level of pain, depression and self-efficacy according to the classifications of pain among chronic pain patients. Method: The data were collected by means of self-reported questionnaire from 164 patients with chronic pain visited in one university hospital and one local pain clinic in Busan, from October 7 to November 16, 2002. Analysis was done by ANOVA, and Scheffe test using SPSS program. Result: The subjects were divided into five classifications of chronic pain : 26.2% low back and extremity pain, 23.2% neck, shoulder and upper extremity pain, 19.5% postherpetic neuralgia, 15.9% complex regional pain syndrome and 15.2% peripheral neuralgia. There were significant differences in pain (p=.000), depression (p=.000) and self-efficacy (p=.003) according to the 5 kinds of chronic pain. With the results of the Scheffe test, the patients with peripheral neuralgia experienced pain and depression higher than those with the other kinds of chronic pain. The patients with neck, shoulder and upper extremity pain experienced self-efficacy higher than those with peripheral neuralgia. Conclusion: Chronic pain patients should be provided effective individualized intervention depending on the classifications of chronic pain. Therefore the development of interventions for pain management according to the classifications of pain in chronic pain patients is needed.

This study aimed to pilot test a newly developed bilateral upper limb rehabilitation training program for improving the upper limb function of individuals with chronic stroke using a visual feedback method. The double-group pretest-posttest design pilot study included 10 individuals with chronic stroke (age >50 years). The intervention (four weekly meetings) consisted of five upper limb training protocols (wrist extension; forearm supination and pronation; elbow extension and shoulder flexion; weight-bearing shift; and shoulder, elbow, and wrist complex movements). Upper limb movement function recovery was assessed with the FuglMeyer Assessment of the Upper Extremity, the Wolf Motor Function Test, the Trunk Control Test, the modified Ashworth Scale, and the visual analog scale at baseline, immediately after, and four weeks after the intervention. The Fatigue Severity Scale was also employed. The Fugl-Meyer Assessment of the Upper Extremity and Wolf Motor Function Test showed significant improvement in upper limb motor function. The Trunk Control Test results increased slightly, and the modified Ashworth Scale decreased slightly, without statistical significance. The visual analog scale scores showed a significant decrease and the Fatigue Severity Scale scores were moderate or low. The bilateral upper limb training program using the visual feedback method could result in slight upper limb function improvements in individuals with chronic stroke.

Taping techniques have been usually used by physical therapists long time ago, which have been considered a useful adjunct to treatment programs for a variety of musculoskeletal disorders. Also, taping techniques may be employed as effective prophylactic methods in clinical setting because of ease application and cost effectiveness. The aims of this study were to describe background information for the management of some chronic low back pain patients with/without leg pain that don't respond to conservative treatment, to demonstrate McConnell taping as successful therapeutic strategies for treating these patients, and to provide detailed application methods of McConnell taping in order that physical therapists can readily use the taping in clinical setting. This study emphasized to illustrate biomechanical benefits of McConnell taping in controlling undesirable muscle activation by decreasing mechanical loads on specific muscles. McConnell taping may be helpful for the inhibition of overactive synergist or antagonists, the facilitation of inactive synergists, the promotion of proprioception, the optimization of joint alignment, pain reduction, and unloading of irritable neural tissue. This study provides taping examples of low back pain, sacroiliac joint dysfunction and lower extremity symptoms associated with these conditions, and discusses the possible mechanisms for their successful application.

Objectives The quality of life in cancer patients is important. The aim of this study is to report a case which showed symptoms improvement after treatment with modified Galgeunhaegi-tang. Methods We retrospectively reviewed the medical records. The patient's body weight and the circumference of lower extremity were measured and the subjective symptoms such as chest pain were evaluated by the NRS(Numeric Rating Scale). And the frequency of defecation was checked daily. Results The patient had received chemotherapy from March to November 2014 for 8th times. During the chemotherapy, the patient developed symptoms such as weight gain, edema of lower extremity, chest pain, headache, low back pain, and constipation. But additional evaluation and management with western medicine couldn't solve the problem. So he started to take Korean medicine. And he was transferred to our cancer center to keep continuing the treatment. After the treatment, the body weight, the lower extremity circumference and the subjective severity of chest pain, headache, low back pain were all decreased. During hospitalization at our center, the patient didn't suffer from constipation. Conclusions An elderly non-small cell lung cancer patient showed the improvement of symptoms that were continued during chemotherapy. As we can see in this case, Korean medicine can be a solution of the symptoms induced by chemotherapy, if there is no symptom improvement with western medicine.

Objective: The purpose of this study was to investigate the effect of sprinter pattern bridging exercise using theraband on activation of lower extremity and abdominal muscle and to find out postures that can effectively improve abdominal and lower extremity muscle strength and increase abdominal stability. Methods: This study was designed as a cross-sectional study. The following research was done with applicants attending S university in Seoul to compare the difference in muscle activity between one-leg-Support bridging exercise and sprinter-pattern bridging exercise using theraband. For 48 study participants, we first measured their MVC. Then, we applied one-leg-support bridging exercise and sprinter-pattern bridging exercise at random order. These data were expressed as the percentage of maximal voluntary contraction (%MVC).Electromyography analysis was performed by measuring the external obliques, internal obliques, biceps femoris, and gluteus maximus. Results: There was a statistically significant increment of muscle activity in external and internal oblique muscle(p<0.001)by sprinter-pattern bridging exercise using theraband. On the lower body, statistically significant increment of muscle activity in biceps femoris and gluteus maximus was found(p<0.05). On the other hand, on erector spinae, there was statistically significant decrease in muscle activity(p<0.05). Conclusions: Efficient treatment is expected when sprinter-pattern bridging exercise using theraband is applied clinically.For patients with chronic knee and ankle pain who have difficulty bearing weight, including low back pain and internal rotation of the femur, starting with a low weight bearing, we think it will be helpful in planning systematic training aimed at progressively strengthening the lower extremities.
