ABSTRACT
Purpose@#This study aimed to compare a dynamic neuromuscular training program with a static neuromuscular training program for taekwondo players. @*Methods@#This study design was a randomized control trial. Three high school taekwondo teams (taekwondo neuromuscular training [TNT] group, 22; Get Set group, 17; and control group, 24) participated in the study. Get Set group performed a program focused on the static movement, and TNT group performed a program which was modified Get Set to dynamic movement. Control group maintained the existing taekwondo training without any intervention. The intervention group performed 15-minute training three times a week for 6 weeks. Dynamic Postural Stability Index (DPSI) and time-to-boundary test (TTB) tests were performed before and after 6 weeks of training. @*Results@#As a result of DPSI, an interaction effect was observed only in the anterior/posterior stability index of the dominant leg of the TNT and Get Set groups (p＜0.05). However, there was no difference between the TNT and the Get Set groups.As a result of TTB analysis, no statistical effect was observed in all variables of the dominant and non-dominant legs. @*Conclusion@#As a result of conducting 6-week dynamic and static neuromuscular training for taekwondo athletes, the effect of training was found in both the intervention group. However, differences in training effects between groups could not be proved. Therefore, it is necessary to clearly confirm the difference between the two training through long-term follow-up studies.
ABSTRACT
Purpose@#Although postural control assessment in patients with chronic ankle instability (CAI) has been thoroughly examined in the literature, few researchers have studied balance strategy in lateral ankle sprain (LAS) copers, who recover from LAS injury with no symptom progression. The purpose of this study was to investigate the difference in center of pressure (COP) variables during static and dynamic posture control among LAS copers, patients with CAI, and ankle healthy controls. @*Methods@#This case-control study recruited 20 patients with CAI, 20 LAS copers, and 20 controls. All participants filled out Ankle Instability Instrument and Foot and Ankle Ability Measure questionnaire and performed single-leg static postural control and Star Excursion Balance Test (SEBT). @*Results@#LAS copers showed less mediolateral COP range as compared to patients with CAI (p=0.001) and control (p=0.001) during static postural control. Furthermore, LAS copers have less anteroposterior COP standard deviation (SD) (p=0.034), range (p=0.009), velocity (p=0.013) than patients with CAI. Relative to patients with CAI, LAS copers had small mediolateral COP SD (p=0.022) and range (p=0.018) during the posteromedial direction of the SEBT.However, there was no significant difference in both mediolateral and anteroposterior COP variables during anterior and posterolateral directions of the SEBT (p≥ 0.05). @*Conclusion@#Based on these observed results, the authors conclude that greater postural control in LAS copers is one of the movement strategies to prevent recurrent LAS as a defense mechanism.
ABSTRACT
Purpose@#Anterior cruciate ligament reconstruction (ACLR) is one of the most common procedures in sports medicine.It is important for patients to determine whether or not to return to the pre-operative state after the ACRL. This study is to evaluate the objective and subjective analysis of the knee joint function and to compare between injured knee and non-injured knee in those with ACLR.Methods: This cross-sectional study recruited 15 individuals with ACLR using autograft (age, 27.87±4.10 years; height, 172.56±4.81 cm; weight, 75.51±13.03 kg; time to surgery, 27.11±14.03 months). International Knee Document Committee subjective knee evaluation form and Lower Extremity Assessment Protocol (LEAP) including muscle strength, static and dynamic postural control, functional task was used to assess the knee joint function. Deficit ratio between injured knee and non-injured knee and independent t-test were used for analysis. @*Results@#Injured knee has significantly decreased isokinetic extension strength (90º/sec), isometric flexion strength and one-leg hopping distance (p＜ 0.05). @*Conclusion@#Although individuals who successfully returned to play (RTP) did not experience subjective dysfunction and pain, there are items of LEAP that indicates deficit ratio between injured knee and non-injured knee. Therefore, when considered whether and when to RTP, it is very important to assess not only subjective dysfunction and pain but also whether the patient has recovered to a level similar to that of the non-injured knee in various aspects of the knee joint.
ABSTRACT
BACKGROUND AND OBJECTIVES: Middle turbinate lateralization is a common complication of endoscopic sinus surgery, and many methods are employed to avoid it. We tried to suture middle turbinate-septum-opposite middle turbinate for middle turbinate stabilization. MATERIALS AND METHOD: A prospective study was done for 32 patients who had floppy or paradoxically curved middle turbinate at the time of endoscopic sinus surgery. A 3-0 Vicryl suture on 20 mm 1/2 curved round bodied needle was used for suture. The needle was passed through the left middle turbinate from lateral to medial, transversing the nasal septum to the right side and continued through the middle turbinate from medial to lateral. It is then passed again in the opposite direction through the same structures and tied. All cases were followed up until complete healing was confirmed by endoscopic visualization at the final office examination. RESULTS: OMUs (Ostiomeatal Units) were patent in 93.7% (30/32) of patients. Middle turbinates of 2 cases were lateralized due to parted suture. In 4 cases (12.5%), patients complained temporary hyposmia during the immediate postoperative period. In 2 cases, patients continued to have hyposmia at 3 postoperative months, but recovered at 6 postoperative months. Crust was observed about 6 weeks. Granulation tissue was presented in 3 cases (9.4%). CONCLUSION: Suture technique is an effective method to stabilize middle turbinate and it can be performed in selected cases of paradoxical middle turbinate or floppy middle turbinate.
ABSTRACT
BACKGROUND AND OBJECTIVES: The tonsillectomy is one of the most common operation in otolaryngology and is performed with a variety of surgical techniques. Convincing evidence in the literature is lacking as far as the optimal method of performing this surgical procedure. So we attempted to find out preferable method of tonsillectomy and to evaluate bipolar scissors tonsillecotmy which is relatively new technique in clinical practice by comparing operation time, intraoperative blood loss, postoperative pain, and postoperative hemorrhage. MATERIALS AND METHOD: The 90 patients admitted to the ENT department for tonsillectomy between March 2002 and May 2002 were entered into this study. All tonsillectomy were performed under general anesthesia. Patients were divided into two study groups, bipolar scissors tonsillectomy and cold dissection. RESULTS: The operation time was shorter and intraoperative blood loss amount was lower in bipolar sissors tonsillectomy than cold dissection. The postoperative pain and postoperative hemorrhage statistically insignificant between the surgical method. CONCLUSION: Bipolar scissors tonsillectomy can significantly reduce the operation time and intaoperative blood loss without increasing the postoperative morbidity.
ABSTRACT
BACKGROUND AND OBJECTIVES : Ageotrophic nystagmus in the horizontal canal BPPV has been explained as a result of cupulolithiasis theory, and has been reported to have the less therapeutic response to conservative rehabilitations than the other type BPPV . Though methods to detach the debris with vibrator have been introduced, the effect has been questioned and it's not physiologic. MATERIALS AND METHOD : We introduce a new head shaking-forced prolonged position method as a more convenient method, and report typical 2 cases of ageotrophic horizontal canal BPPV managed with it and analyzed results of 25 cases all told. RESULTS AND CONCLUSION : The average number of rehabilitation was less than two, and loss of direction changing positional nystagmus could be observed immediately after rehabilitation.

BACKGROUND AND OBJECTIVES: Canalith repositioning procedure (CRP) is an effective treatment for benign paroxysmal positional vertigo (BPPV). However, there is a significant number of patients who require multiple treatment visits for reliefs of symptoms. The purpose of this study is to identify factors that may be associated with these difficult to treat cases. MATERIALS AND METHODS: A retrospective review was made of 179 patients who were diagnosed as BPPV. 20 patients who required more than three treatment visits for CRP were included in this study. Statistical analysis included age and sex of patients, the kind of involved semicircular canal (SCC), direction of nystagmus, latency of nystagmus on electronystagmography (ENG) and duration of symptoms. RESULTS: There was no significant statistical association between the number of treatment visit and patient's age, sex. Although significant statistical association was not found, the therapeutic efficacy of lateral SCC BPPV was lower than that of posterior SCC BPPV. In the cases where the direction of nystagmus was ageotrophic, the efficacy of CRT was decreased and statistical significant association was found. Also when short latency of nustagmus on ENG and long duration of symptoms appeared, more trial of CRP was needed and statistical significant association was found. CONCLUSION: In the treatment of BPPV by CRP, we can consider latency of nystagmus on ENG, duration of symptoms, direction of nystagmus and type of involved semicircular canal as prognostic factors.

Tracheopathia osteoplastica (TO) is a rare clinical and pathologic benign condition that causes irregularity, narrowing and rigidity of the trachea and the main bronchi, characterized by multiple submucosal cartilaginous and osseous nodules of various sizes lining the upper respiratory tract. The treatment of TO diagnosed with CT and bronchoscopic biopsy is mostly supportive, and sometimes laser vaporization is used. We experienced a case of TO with severe obstructed airway that was treated by drilling.

Tonsillar tuberculosis is uncommon and is almost secondary to pulmonary tuberculosis. Primary tonsillar tuberculosis is very rare, especially in children. The incidence of tuberculosis has been greatly reduced with chemotherapy, although it has not been eradicated. Recently, we experienced one case of pediatric primary tonsillar tuberculosis of left palatine tonsil. It was diagnosed pathologically after tonsillectomy and adenoidectomy. The purpose of this report is to point out that primary tonsillar tuberculosis still exists and to draw attention to the differential diagnosis in children.

BACKGROUND AND OBJECTIVES: Deep neck space infections, which affect soft tissues and fascial components of the head and neck, were frequently encountered in the preantibiotic era, but their frequency has been remarkably reduced after the development of chemotherapeutic agents and antibiotics. However, they may still result in significant morbidity and mortality despite the use of chemotherapeutic agents and antibiotics. The purposes of this study has been to assess clinical findings and the effectiveness of the treatment of deep neck infection through statistical analysis. MATERIALS AND METHODS: A retrospective study was performed on 86 cases of deep neck space infections in patients admitted for diagnosis and treatment during a 9-year period from January 1988 to December 1996. RESULTS: All cases were treated with either conservative treatment only as in 47 cases (55%), or surgical drainage and antibiotics as in 33 cases (33%), or surgical drainage with tracheostomy and antibiotics as in 6 cases (7%). At the end of the treatment, 83 cases were cured of the disease and 3 cases were reported to have complications. CONCLUSION: We concluded that treatment of deep neck infection requires knowledge of the natural history of the disease and a detailed understanding of anatomy. Management guidelines include (1) hospitalization, (2) culture and sensitivity tests, (3) antibiotic therapy, (4) diagnostic radiographic procedures, and (5) surgical intervention.
