Objective : In order to study the effect of contralateral acupuncture on recovery of motor disorders in stroke patients a clinical study was performed. Methods : Thirteen patients with poststroke-hemiplegia were randomized into two groups. Six patients(test group) treated with contralateral acupuncture. The other seven patients(control group) treated with ipsilateral acupuncture. The activity of daily living was measured with a modified barthel index(MBI). The therapy was performed one a day for 3 weeks. Results : In terms of improvement of activity of daily living, the test group showed statistically meningful increase after 1 week treatment. but the control group showed statistically meningful increase after 2 weeks(p<0.05). In terms of score of MBI, the groups showed no statistically meningful difference after 3 week treatment. Conclusions : These results support that contralateral acupuncture therapy has almost same effectness compared with ipsilateral acupuncture therapy in improvement of the activity of daily living of poststroke-hemiplegic patients.

Objective : In order to study the effect of contralateral both side acupuncture on recovery of motor disorders in stroke patients, a clinical study was performed. Methods : Thirteen patients with post-stroke hemiplegia were randomized into two groups. Six patients (test group) were treated with contralateral both side acupuncture. The other seven patients (control group) were treated with ipsilateral both side acupuncture. The activity of daily living was measured with a National Institutes of Health (NIH) scale. The therapy was performed once a day for 3 weeks. Results : In terms of score of NIH, the test group showed statistically meaningful increase after I weeks treatment, while the control group showed statistically meaningful increase after 2 weeks (P<0.05). The results showed no statistically meaningful difference after 3 weeks treatment between the groups. Conclusions : These results support that contralateral both side acupuncture therapy has almost the same effectiveness compared with ipsilateral both side acupuncture therapy in improvement of the activity of daily living of post-stroke hemiplegic patients.

This study aimed to investigate whether isometric lower limb exercise can activate contralateral trunk muscles and whether the magnitude of muscle activation is related to lower limb movement in sitting. This study included 25 healthy young subjects (20 males and 5 females). The magnitude of trunk muscle activation was measured using surface electromyography (EMG) during hip flexion, extension, adduction, and abduction, and a significant difference was observed in the activation levels of trunk muscles among the tests (p<.01). The EMG activity of the multifidus (MF) and erector spinae (ES) muscles on the contralateral side were significantly greater during hip extension. However, the activation levels of the contralateral internal oblique (IO) and rectus abdominis (RA) muscles were greatest during hip flexion. The MF : ES EMG ratio was significantly greater during hip isometric during hip isometric flexion and abduction compared to hip extension and adduction. There was no significantly difference in the IO : RA ratio during the isometric contractions toward different directions. These findings indicate that isometric lower limb exercise can elicit trunk muscle contraction on the contralateral side and may therefore be helped for developing contralateral trunk muscle strength in individuals undergoing rehabilitation.

Background: The purpose of this study was to investigate the effects of ipsilateral and contralateral load changes during single-leg standing on the leg muscle activities of healthy people. Design: Randomized controlled trial. Methods: For all the subjects, a load was randomly applied to the ipsilateral or the contralateral side. While the load was applied, the subject raised a hand and then performed single-leg standing for 10 seconds using the dominant side. Results: During single-leg standing, the muscle activity of the gluteus medius, peroneus longus on the supporting side increased statistically significantly when an upper limb load was applied contralaterally, but no statistically significant differences were detected in the muscle activities of the tibialis anterior and the gastrocnemius using a test of within-subjects effects. Conclusion: It can be seen that muscle activities increase during exercise when the amount and frequency of a load are increased and when the same load is applied to different sides of the body. Such muscle activity increases may be applied to change the intensity of exercise when one is in a static posture, such as during single-leg standing.

Purpose: The purpose of this study was to examine effects of decreased locomotor activity on mass, Type I and II fiber cross-sectional areas of ipsilateral and contralateral hindlimb muscles 21 days after establishing the Parkinson's disease rat model. Methods: The rat model was established by direct injection of 6-hydroxydopamine (6-OHDA, 50 ${mu}g$) into the left substantia nigra after stereotaxic surgery. Adult male Sprague-Dawley rats were assigned to one of two groups; the Parkinson's disease group (PD; n=17) and a sham group (S; n=8). Locomotor activity was assessed before and 21 days after the experiment. At 22 days after establishing the rat model, all rats were anesthetized and soleus and plantaris muscles were dissected from both ipsilateral and contralateral sides. The brain was dissected to identify dopaminergic neuronal death of substantia nigra in the PD group. Results: The PD group at 21 days after establishing the Parkinson's disease rat model showed significant decrease in locomotor activity compared with the S group. Weights and Type I and II fiber cross-sectional areas of the contralateral soleus muscle of the PD group were significantly lower than those of the S group. Conclusion: Contralateral soleus muscle atrophy occurs 21 days after establishing the Parkinson's disease rat model.

Purpose: The purpose of this study was to investigate the effects of a four week unilateral isokinetic exercise program applied to ankle on the one-leg stance balance performance of ipsilateral and contralateral lower-limbs. Methods: Subjects were randomly assigned to either a right ankle training program (n=12) or a control group (n=12). The training group received unilateral ankle isokinetic exercise of the dominant side for 4 weeks, whereas control group did not. Ipsilateral and contralateral one-leg balance were measured before and after intervention using the Biodex Balance System. Results: Improvements of stability scores, such as APSI, MLSI, and OSI, from pre-test to post-test were significantly different greater for the training group when the control. Conclusion: The results of this study suggest unilateral ankle strengthening exercise transfers benefit to the untrained limb by a cross-education effect, and that this type of exercise should be considered to improve one-leg standing balance of trained and untrained lower-limbs.

Objective : This study designed to find out the effects of deep acupuncture in cerebrovascular hemiplegia. Methods : This study was performed on 30 patients with cerebrovascular hemiplegia to observe difference in temperature of skin surface between general acupuncture and deep acupuncture at Hapkok using digital infrared thermographic imaging(D.I.T.I.) Results : 1. Temperature of paralytic side is sigficantly higer $0.39{\pm}0.78^{\circ}C$ than that of contralateral side. 2. Thermal difference(${\Delta}T$) of paralytic side-contralateral side decreased $0.08{\pm}0.53^{\circ}C$ after general acupuncture, but there is no significant. $0.20{\pm}0.50^{\circ}C$ after deep acupuncture decreased significantly. So deep acupuncture is more effective than general acupuncture. 3. Thermal difference of paralytic side-paralytic side and contralateral side-contralateral side decreased significantly after acupuncture, and thermal difference of deep acupuncture on paralytic side-paralytic side decreased $0.42{\pm}1.07^{\circ}C$ more than that of general acupuncture. So deep acupuncture is more effective than general acupuncture. Conclusions: This study showed that deep acupuncture is more effective than general acupuncture In cerebrovascular hemiplegia, and further study is needed on clinical trials.

Purpose: This article was conducted to determine the immediate effects of unilateral contract-relax (CR) stretching on contralateral knee extension range and to compare both sides of the knee extension range between experimental and control groups. Methods: This study recruited 16 adult males and females with straight leg raising abilities below $90^{\circ}$. The subjects were randomly divided into an experimental group and a control group comprising 8 subjects each. The experimental group performed direct CR stretching on the right hamstring muscles with straight hip extension adduction, and the control group performed indirect CR stretching on the right hamstring muscles with straight hip flexion abduction. Each group performed CR stretching 4 times with 4 repetitions comprising 10 sec of contraction and a 10 sec break between repetitions. Before and after the CR stretching exercises, the subjects' passive knee extensions were measured at the hip in a $90^{\circ}$ flexed position. The subjects' peak force on the right leg and peak pressure on the left leg during each CR stretching exercise were also measured. Results: After doing CR stretching 4 times, each group showed a significantly increased passive knee extension range on both sides, and there was no difference in the passive knee extension ranges between the groups. The peak force on the right leg was significantly higher in the experimental group than the control group. There was no difference in peak pressure between the groups. Conclusion: After applying unilateral CR stretching, the study subjects experienced a significantly increased passive knee extension range on the contralateral side. For patients who find it difficult to apply stretching techniques to knee joints directly, the use of the proprioceptive neuromuscular facilitation technique of CR stretching may be useful in improving the range of the knee joint on the contralateral side without direct treatment.

It is well known that the acupuncture has been used effectively for the relief of certain types of pain. Although the precise mechanism of action of acupuncture analgesia is unknown, it is generally accepted that their analgesic properties are related to the activation of endogenous opiate system in central nervous system. And it is suggested that pain-relieving properties of acupunture may be related to a stimulation of peripheral nerve underlying the acupuncture point on the skin. However, the efficacy of acupuncture has no relationship between the site of pain and the acupuncture point. Consequently, the present study was undertaken to investigate electroacupuncture analgesia in relation to the site of peripheral nerve stimulation. Cats were decerebrated ischemically and the flexion reflex as an index of pain was elicited by stimulating the sural nerve (20V, 0.5 msec duration) and recored as a compound action potential from the nerve innervated to the posterior biceps femoris muscle in the ipsilateral hindlimb. Bilateral common peroneal nerve and contralateral superficial radial nerve were selected as the site of peripheral nerve stimulation. For the stimulation of peripheral nerve, a stimulus of 20 V intensity, 2 msec-duration and 2 Hz-frequency was applied for 60 min respectively. The results obtained are summarized as follows: 1) Both stimulation of contralateral common peronal nerve and contralateral superficial radial nerve did not change the flexion reflex and there were no significant differences between them. 2) Stimulation of ipsilateral common peroneal nerve markedly depress the flexion reflex, the effect being reversed by naloxone application. These results suggest that stimulation of ipsilateral common peroneal nerve has the analgesic effect but both stimulation of contralteral common peroneal nerve and contralateral superficial radial nerve to the pain site where flexion reflex was elicited have no analgesic effect.

Objective: Arthrocentesis is a minimally invasive surgical procedure that is used to alleviate the symptoms of temporomandibular joint (TMJ) disorders. The aim of this study was to investigate the effect of arthrocentesis on the blood supply to the retinal structures. Materials and Methods: Arthrocentesis was performed on 20 patients with TMJ disorders, and choroidal thickness (CT) in patients was measured to evaluate retinal blood circulation. The blood volume of the retinal structures was evaluated ipsilaterally before and after arthrocentesis, and these measurements were then compared with measurements obtained from the contralateral side. Results: Before arthrocentesis, there were no differences in retinal blood volumes between the ipsilateral and contralateral sides (P = 0.96). When ipsilateral CT measurements taken before and after arthrocentesis were compared, retinal blood supply was found to have significantly decreased after arthrocentesis (P = 0.04). When contralateral CT measurements taken before and after arthrocentesis were compared, retinal blood supply was also found to have decreased after arthrocentesis, but not significantly (P = 0.19). Conclusion: The solution of local anesthesia with epinephrine applied before the arthrocentesis procedure was found to reduce the blood volume of the retinal structures. To the best of our knowledge, this is the first study that has investigated the blood volume of the retinal structures following arthrocentesis.
