The objective of this study is to determine the effects of static and dynamic stretching exercises on the gastrocnemius muscle-tendon properties by use of ultrasonography. Twenty healthy adults participated in the present study. The subjects were asked to engage in static and dynamic stretching exercises of the gastrocnemius for 30 sec each in 2 sets. Ultrasonography to measure the displacement of the myotendinous junction (MTJ) was performed at the 0 sec, 30 sec, 60 sec, 180 sec, and 300 sec after the stretching exercises. A significant displacement of the static stretching was observed between the 0 sec and 30 sec, and between the 180 sec and 300 sec (p<0.05), with no significant changes between the 30 sec and 180 sec. And dynamic stretching exercise showed more significant displacement in the all conditions compared with static stretching (p<0.05). The displacement of the MTJ position was observed in proximal parts, and dynamic stretching appeared to make the change in distal parts. Therefore, static and dynamic stretching exercises of the gastrocnemius showed different change rate and position displacement direction.

Objective: Robot assisted gait training is implemented as part of therapy for the recovery of gait patterns in recent clinical fields, and the scope of implications are continuously increasing. However clear therapy protocols of robot assisted gait training are insufficent. The purpose of this study was to investigate the effects of robot-assisted gait training applied with guidance force on balance and gait performance in persons with hemiparetic stroke. Design: Two group pre-test post-test design. Methods: Nineteen persons were diagnosed with hemiparesis following stroke participated in this study. The participants were randomly assigned to the unilateral guidance group or bilateral guidance group to conduct robot-assisted gait training. All participants underwent robot-assisted gait training for twelve sessions (30 min/d, 3 d/wk for 4 weeks). They were assessed with gait parameters (gait velocity, cadence, step length, stance phase, and swing phase) using Optogait. This study also measured the dynamic gait index (DGI), the Berg balance scale (BBS) score, and timed up and go (TUG). Results: After training, BBS scores were was significantly increased in the bilateral training group than in the unilateral guidance group (p<0.05). Spatiotemporal parameters were significantly changed in the bilateral training group (gait speed, swing phase ratio, and stance phase ratio) compared to the unilateral training group (p<0.05). Conclusions: The results of this study suggest that robot-assisted gait training show feasibility in facilitating improvements in balance and gait performance for subacute hemiparetic stroke patients.

OBJECTIVE: To examine the potential role of cerebral revascularization in the treatment of patients with symptomatic occlusive cerebrovascular disease refractory to medical therapy, we prospectively reviewed 12 patients who underwent extracranial- intracranial (EC/IC) bypass surgery. METHODS: A series of 12 patients treated in a 3-year period met the following criteria, 1) symptomatic internal carotid artery(ICA) or middle cerebral artery (MCA) obstruction or stenosis over 80%,2) decrease in basal cerebral blood flow (CBF) over 10%,3) hyporeactivie CBF to acetazolimide. Among them, the type of ischemic episode was transient ischemic attack (TIA) in seven, minor stroke in four , and major stroke in one. Of these, nine patients had multiple episode of ischemic attack. CT or MRI showed infarction of the MCA territory in two , border zone infarction in three, basal ganglia infarction in two and multiple lacunar infarction in five. Angiographic findings included internal carotid artery occlusion in ten patients and middle cerebral artery occlusion in two. Based on our criteria, superficial temporal artery (STA)-MCA anastomosis was performed in 12 cases. RESULTS: Average follow up period was 21.58 months. Postoperative course was uneventful in ten patients. One patient suffered a postoperative stroke (hyperperfusion syndrome) with complete recovery and another suffered an operative wound infection. Of the 12 patients, 11 (91.6%) have had an excellent to good outcome with complete resolution or significant improvement of preoperative neurologic symptom, while remaining one showed no improvement. Bypass patency was confirmed by postoperative angiography in all cases. Postoperative follow up studies of the basal CBF and response of the CBF to the acetazolamide showed significant increased CBF activity to acetazolamide in 11 cases (91.6%) while the basal CBF was essentially unchanged in all cases except for two. CONCLUSION: Although the Cooperative Study on Extracranial-Intracranial Bypass failed to show a benefit from the bypass procedure, carefully selected individuals with occlusive cerebrovascular disease and persistent ischemic symptoms, despite maximal medical therapy, seem to obtain remarkable benefit from cerebral revascularization. Our results suggest that EC-IC bypass surgery should be considered in patients with hemodynamic cerebral ischemia in order tp improve the cerebrovascular reserve capacity.

Meningococcal infection is a life threatening disease that leaves serious sequelae in spite of appropriate treatment, thus vaccination for high risk groups are important for the prevention of meningococcal diseases. However, the vaccine for Neisseria meningitidis has not been available in Korea until we introduced bivalent (serogroup A and C) polysaccharide vaccine for the first time for relief works in our university hospital. The vaccine was administered from January 2005 to March 2007 to 317 persons. Of the groups administered, the largest group among them were 133 (133/317, 42%) students who planned to study abroad and needed the vaccination for secure entrance to school dormitories. This group was followed by health care workers, travellers to the regions of the world with high risks of meningococcal diseases, and splenectomised patients. To rationalize the domestic use of meningococcal vaccine, the availability of vaccines first needs to be simplified by introducing them to the domestic market; for this to be possible, the approval system for vaccines should be reformed and epidemiogical studies need to be carried out.
