This study is to define how the difference of athletic change influence on the last regrasp after somersault in Belle movement of parallel bars. For his study, the following conclusion was produced by analysis of athletic change by means of three dimensional visual image in three athlete of nation. 1. As the picture of S1, there are total used time(2.01 sec), S3(2.17 sec) and S2(2.19 sec). In case of a short needed time, it is difficult for them to perform the remaining movement of the vertical elevating flight easily and comfortably, it is judged as performing the small movement with restrict swing. 2 In the change of body center sped by each event, it is calculated as $-89.1^{\circ}$ the narrowest in S1, $-81.96^{\circ}$ the widest and then $86.34^{\circ}$ in S3. In E3 event, average compound speed is 4.07m/s, S2 showed the fastest speed of 4.14m/s whereas S1 the narrowest angle of 3.95m/s. 3. A shoulder joint and coxa are the period of mention in E3. In E4 which was pointed out the longest vertical distance, S2 that is indicated the highest vertical height as the period of detach in parallel bars. showed -3.91m. This is regarded as a preparatory movement for dynamic performance after using effectively elastic movement of shoulder joint and coxa while easily going up with turning back movement. In the 5th phrase, long airborne time and vertical change position is showed as the start while regrasping securely air flight movement from high position. 4. In E5, a long flight time and a long vertical displacement were shown as the regrasp after somersault efficiently in high position with stability from the point of the highest peak of the center of the body. Especially, S2 is marked as a little bit long position, while S1 is reversely indicated as performing somersault and unstable motion in a low position. 5. In E3, at the point of the largest extension of the shoulder joint and hip joint the shoulder joint is largely marked in $182^{\circ}$ and the hip point $182^{\circ}$ in S2. The shoulder joint is marked at the smallest angle in $177^{\circ}$ and the hip point $176^{\circ}$ in S1. And S1 is being judged by its performance of the less self - confident motion with lessening a breath of swing. S2 makes the most use of flexion and extension of the shoulder joint and the hip joint effectively. It was performed greatly with swinging and dropping the rotary movement and the rotary inertia naturally. 6. In E6, as the point of regrasp of the upper arm in parallel bars it is recognized by the that of components of vertical and horizontal velocity stably. During this study, the insufficient thing and the study on the parallel bars at a real game later are more activated than now. If it is really used as the basic materials by means of Belle Picked Study of Super E level after Bell movement, you may perceive the technique movement previously and perform without difficulty. Especially, such technique as crucifix is quite advantageous for oriental people thanks to small body shape condition. In conclusion we will nicely prepare for our suitable environment to gradually lessen trials and errors by analyzing and studying kinematically this movement.

Objectives: To assess the functional outcome of Bankart repair and rotator cuff repair using miniopen technique in patients with recurrent shoulder dislocation(8 cases) with rotator cuff tears and Bankart lesion of over 40 years. Materials and Methods: From May 1991 to January 2002, twenty two patients were available to participate in the study. Mean age was 52 years old(41-67), Follow-up evaluations averaged 50.5months(10-147). Results: The patients(22 cases) were divided into two groups. Group 1: with recurrent shoulder dislocation(8 cases) with rotator cuff tears and Bankart lesion in patients over 40 years old. Group 2: without Bankart lesion(14 cases). In Group 1, mean average of forward flexion and abduction improved from 122 degrees to 154 degrees at the final follow-up and from 115 degrees to 161 degrees respectively. In terms of University of Pennsylvania patient self-assessment of pain score and VAS, scores improved from 11.0 to 5.5 and from 5.4 to 2.5 respectively. In terms of UCLA score & Constant score, scores also improved from 20.2 to 29.6 and from 48.6 to 69.0 respectively. Functional outcome of Group 1: two patients with excellent, four patients with good, and two patients with fair. Functional outcome of Group 2: two patients with excellent, six patients with good, five patients with fair, and one patient with poor. But they had no statistical significance between the two groups. All cases were improved shoulder pain at the final follow up. And six patients were satisfied with the outcome of shoulder function. Conclusions: This study demonstrates the effectiveness of Bankart repair and rotator cuff repair using miniopen technique in patients with recurrent shoulder dislocation(8 cases) with tears of rotator cuff and Bankart lesion older than 40 years. We recommend Bankart repair and rotator cuff repair at the same time.

Clinical observation was made on 44 cases of stable thoracolumbar compression fracture that were confirmed through simple x-ray and neurological examination. They were hospitalized and treated by acupuncture and moxibustion, bed rest, herb medicine and physical therapy. If necessary, patient was given an enema. The results obtained are as follows. 1. The patient distribution ratio, in regard to sex, was shown to be 1: 13.7 for males to females. In regard to age, it was shown that people in their 60's was the most predominant case, followed by people in their 70's, 80's, 50's and 40's, respectively. 2. In regard to contributing factors, it was observed that accidental falls were most frequent, followed by reasons unknown, repetitive lifting of heavy objects, overlaboring and bruise in that order. 3. In regard to duration of illness before treatment, it was found that treatment within 1 week was most predominant, followed by over 4 weeks, and 1-2 weeks, respectively. 4. With regard to the duration of hospitalization, hospitalization within 2 weeks was found to be most predominant, followed by 2-4 weeks. 5. In regard to the level of the affected vertebral body; The affected vertebral bodies distributed between T3 to L5 except for T7; T12 was found to be most predominant, followed in turn by L1 and L5. 6. In regard to the number of affected vertebral bodies, 2 was the most frequent followed by 1 and 3, in that order. The average of the number of affected vertebral bodies was observed to be 2.8 and single vertebral body compression fracture was shown to have no clinical and statistical difference as compared with multiple vertebral body compression fractures. 7. In regard to the grade of the seriousness of symptoms, it was found that Grade IV was most predominant, followed by Grade III. 8. With regard to signs at the first medical examination, low back pain was seen in the highest number, and followed in order by gait disturbance, flank pain, flexion-extension disturbance, disturbance of rotation to right or left, and bowel dysfunction. 9. Concerning the effect of treatment, good results were most predominantly seen, and 95.5% of total patients showed fair results. 10. The duration of admission treatment due to the grade of clinical symptoms was as follows; In the case of the Grade IV, it was observed that within 2 weeks was most predominant and for Grade III was 2-4 weeks. It was also found that the grade of clinical symptoms was not in proportion to the duration of admission treatment. 11. In regard to the result of treatment due to the grade of clinical symptoms; It was found that in the case of Grade IV, within 2 weeks was most predominant, and for Grade III, it was found to be 2-4 weeks. 12. Intestinal obstruction was shown in 50% of total patients; In the case of duration of constipation, more than 1 week was found to be most predominant, followed by 2 and 4 days respectively. 13.

Background: During movement the major inputs to nervous system come from firstly the muscle and joint to maintain posture and motion and secondly the chemoreceptors and baroreceptors to adjust the cardiovascular and respiratory function. Their complex relationships are generally studied for many years but the direct relation between the joint and respiratory system is not studied thoroughly until now. So this experiment was performed to determine whether the natural movement of knee joint can cause the enhancement of respiratory function by observation of the changes of respiratory rate, phrenic nerve activity and inspiratory neuron activity during the stimulation of knee joint in cat anesthetized with $\alpha$-chloralose. Method: Twenty six male adult cats were used and the extracelluar recording using bipolar platinum electrode and carbon filament electrode was done to record the changes in the activities of phrenic nerve and inspiratory neuron movement of knee joint, injection of chemicals into the joint cavity and electrical stimulation of articular nerve were done. Results: The 60 Hz. could not but 120 Hz. flexion-extension movement of knee joint increased respiratory rate(R.R.), tidal neural activity(TNA) and minute neural activity(MNA). Intra-articular injection of lactate could not increase R.R. but significantly increase TNA and MNA which represented the enhanced respiratory function. Injection of potassium chloride showed similar effects with the case of lactate but the duration of effect was shorter. The electrical stimulation of medial articular nerve with IV strength which could activate only group I and II afferents showed increased TNA and MNA during stimulation but 20 V stimulation which could activate all the afferents increased all the respiratory parameters. The changes of inspiratory neuron activity by knee joint stimulation was similar to that of phrenic nerve. Conclusion: The respiratory center could be directly stimulated by the activation of group I and II articular afferents and it seemed that the magnitude of the respiratory center enhancement is proportional to the amount of sensory information from the knee joint. These facts might suggest that the respiratory function could be enhanced even by the normal movement of knee joint.

The aim of this study was to evaluate Influence on intra-limb coordination in individuals wearing knee brace during walking. Seven healthy male adults ($32.3{\pm}2.7$ years old, $175.2{\pm}3.8cm$, $76.2{\pm}8.7kg$) participated. They wore knee brace or didn't wear any knee brace and were asked to walk along a 10 m long walkway. Spatiotemporal parameters, angles of the lower limbs, and intra-limb continuous relative phase (CRP) were measured and calculated. No differences of spatiotemporal parameters were shown (all p > 0.05). There were no changes in the angle and its range of motion (ROM) in the hip for the subjects as wearing knee brace, while ROM ($65.5{\pm}3.7^{\circ}$ vs. $60.5{\pm}3.5^{\circ}$, p < 0.05) of the angle and maximum flexion angles (stance: $31.9{\pm}4.6$ vs. $25.6{\pm}5.5$, swing: $76.7{\pm}3.1$ vs. $68.9{\pm}3.4$, all p < 0.05) in the knee significantly decreased. No changes in ROM of angle in the ankle were shown, whereas maximum dorsiflexion decreased ($22.4{\pm}2.6$ vs. $19.2{\pm}2.1$, p < 0.05) and maximum plantarflexion increased ($9.5{\pm}3.0$ vs. $15.7{\pm}2.2$, p<0.05). There were no changes in most of CRP between joints. CRP between the hip and knee joints decreased ($93.0{\pm}7.8$ vs, $84.7{\pm}4.9$, p < 0.05). Most of CRP standard deviation increased (between the hip and ankle joint during swing: $25.1{\pm}6.7$ vs. $32.4{\pm}1.9$, between the knee and ankle joint during stance: $46.0{\pm}12.9$ vs. $80.1{\pm}31.1$, between the knee and ankle joint during swing: $34.5{\pm}4.1$ vs. $37.6{\pm}3.1$, all p < 0.05). These results indicated that wearing knee brace affected joint angle and intra-limb coordination, but less affected gait features.

Purpose: Primary osteoarthritis on the elbow is the result of the growth of osteophytes and contracture of the capsule. It often causes disability on joint motion and pain while exercising. As arthroscopy has developed, the arthroscopic diagnosis and treatment of the elbow have recently become more generalized as well. Therefore, we like to report on arthroscopy for treating elbow arthritis and its results. Materials and Methods: This study includes 23 cases of elbow arthritis that were seen between 2005 June to 2007 June and these patients didn't response to conservative treatment. From this we excluded 18 cases that underwent arthroscopic surgery and among these 18 cases, 6 cases underwent ulnar nerve transfer. The average observation time was 21.3 months and the average age was 48.4 years (range: 22-66 years). The pre and post operative pain was evaluated with using the Visual Analogue Scale (VAS) and functional evaluation was done with using the Mayo elbow Performance Score (MEPS) with the range of joint motion. Results: The VAS score at the last follow up was significantly decreased from 3.4 to 1.9 compare to the preoperative score. The range of joint motion was improved by 25 (0-40) to 8.5 (0-20) in extension and 101.7 (80-140) to 125.2 (85-140) in flexion (p<0.05). The MEPS always showed significant improvement by showing an increase from 65.4 (40-85) to 87.9 (55-100). However, 3 cases showed a decreased range of motion after the operation. One case showed ulnar nerve symptoms after surgery. Conclusion: An arthroscopic procedure can treat the pathologic processes associated with arthritis of the elbow and it was safe and effective in this series.

Purpose: We wanted to evaluate the surgical results of early mobilization after rigid fixation of small coronoid fracture using the tension band technique Materials and Methods: Eight cases of coronoid fracture were fixed with the tension band technique and using K-wire and wire through the medial approach. All the cases were Regan-Morrey type 2. According to O'Driscoll, they were classified as 5 cases of the tip type (subtype 2) and 3 cases of the anteromedial type (1 case of subtype 2, and 2 case of subtype 3). The associated collateral ligament injuries (6 cases) and radial head/neck fractures (4 cases) were managed simultaneously. After immobilization for 5~7 days, active ROM exercise with a fitted hinge brace started and continued till postoperative 6 weeks. The patients were assessed for pain, ROM and functional disability using the Mayo elbow performance score (MEPS) at an average of 11 months (range: 6~28 months). The ulnar nerve symptoms were also investigated. Results: We observed solid union in all the coronoid fractures without hardware failure. An average of 2.2 wires (range: 2~4) were used. The mean extension was $3^{\circ}$(range: $0^{\circ}\sim25^{\circ}$), the mean flexion was $137^{\circ}$(range: $130^{\circ}\sim140^{\circ}$), the mean pronation was $69^{\circ}$(range: $45^{\circ}\sim90^{\circ}$) and the mean supination was $78^{\circ}$(range: $45^{\circ}\sim90^{\circ}$). The mean MEPS was 96 (range: 65~100). Ulnar nerve symptoms occurred at postoperative one day and persisted in one patient with the terrible triad of taking radial head excision and residual medial instability. Conclusion: The tension band technique uses easily obtained, economic K-wires and the wire was strong enough to permit early elbow ROM exercise and the technique might improve the elbow function. It was especially useful for fixation of multiple small fragments.

Purpose : We evaluated radiographic changes and clinical manifestations of the elbow joint to identify the effects of the throwing between dominant and non-dominant arms. Materials and Methods : A hundred and five little leaguer’s baseball player in 5 elementary school and 2 middle school were evaluated for clinical symptoms and radiographic changes about elbow joint. Mean age was 12 years old and average periods of exercise were 32 months. Elbow functions were evaluated using ASES standardized assessment form and radiographic changes of medial epicondyle were examinated for enlargement, separation of the apophyses, fragmentation and irregularity. Results : Thirty seven players (35$\%$) were complained pain with throwing and the average score was 4.8 using visual analog scale. There were no significant differences in range of motion except flexion angle, valgus angle, and strength between dominant arm and non-dominant arm. Valgus laxity was more prominent in dominant arm. Ulnohumeral tenderness, radiocapitellar tenderness and medial flexor origin tenderness were in 18, 6, and 17 cases respectively in dominant arm. Medial epicondyle was enlarged in dominant arm with 13.0 by 6.3 mm compared to non-dominant arm with 11.7 by 6.1 mm. Apophyseal separation was 0.8 mm in dominant arm and 0.5 mm in non-dominant arm. Fragmentation and irregularity were 14 (13$\%$) and 25 (24$\%$) cases respectively in dominant arm. Conclusion : In little league baseball player, it needs usage of ball and bat with appropriate weight, and careful conditioning programs through throwing exercise in order to avoid elbow injuries.

This study was a systematic review and meta-analysis comparing the effects of aquatic exercise and land-based exercise in the treatment of knee osteoarthritis. 7 studies (n=449) met selection and exclusion criteria out of 287 potential studies obtained from the literature search via Ovid-Medline, Cochrane Library CENTRAL, CINAHL, RISS and KISS. The overall risk of bias of selected studies using SIGN (Scottish Intercollegiate Guidelines Network) checklist for randomized controlled trials (RCT) was regarded as low. As a result of meta analysis, Standardized Mean Difference (SMD) for pain was -0.26(95% CI -0.49, -0.03, p=0.03, $I^2=14%$), which implies that aquatic exercise groups had significant less pain than land-based exercise groups. On the other hand, there was no significant difference between aquatic exercise groups and land based exercise groups for flexion Range of Motion (ROM) (-0.12, 95% CI -0.51, 0.27, p=0.53, $I^2=0%$), extension ROM (-0.04, 95% CI -0.55, 0.48, p=0.89, $I^2=43%$), physical function (-0.12, 95% CI -0.44, 0.19, p=0.44, $I^2=0%$), Quality of Life (QOL) (-0.15, 95% CI -0.54, 0.24, p=0.46, $I^2=0%$). This study has some limitations due to few RCTs comparing aquatic exercise groups and land-based exercise groups in the treatment of knee osteoarthritis. Therefore, further RCTs should be conducted along with long-term outcomes.

Purpose: This study reported the outcomes following the use of bioabsorbable knotless anchor in patients with anterior instability of shoulder. Methods: We studied fifteen cases with traumatic anterior shoulder instability underwent arthroscopic Bankart repair with bioabsorbable knotless suture anchor between January 2003 and June 2003. Among fifteen patients, fourteen were male and one was female, with a mean patient age of 24 years (range 16-42). The mean follow-up was 14 months (range 12-18 months). We compared with operation time of twenty cases of arthroscopic Bankart repair by the suture anchor technique between January 2002 and October 2002. Results: Neither recurrent dislocation nor subluxation was happened in postoperative follow-up. Mean score for functional evaluation by Rowe et al. was 89.4 and that for patient subjective satisfaction was 87,5. At last follow-up period, average shoulder range of motion for flexion and external rotation was 171$^{\circ}$ and 54$^{\circ}$ respectively. All patients were satisfied except three who had an apprehension at the follow up. During Bankart repair, it took an average of 25.5 minutes for one knot with the use of suture anchor technique whereas an average of 16.5 minutes for one knot with the use of bioabsorbable knotless anchor. Significantly, we saved operation time with the use of bioabsorbable knotless anchor (P<0.05).Conclusion: Repairing the Bankart lesion with the use of knotless anchor technique has the advantage of obtaining good capsular tensioning and saving operation time. And it is considered to be very successful in treating shoulder instability without recurrent dislocation or subluxation.
