Objective: The purpose of this study was to investigate the effects of vibration resistance exercise (VRE) in patients with tennis elbow on strength, range of motion (ROM), function, pain and quality of life (QOL). Design: Randomized controlled trial. Methods: Twenty-seven participants were randomly assigned to either the VRE group (n=9), weight resistance exercise (WRE) group (n=9) or control group (n=9). Each group underwent hot compress for 15 minutes and electrotherapy for 15 minutes. The VRE group underwent exercises using a vibrating ball for 5 minutes. The WRE group underwent exercises using dumbbells for 5 minutes. All participants were evaluated on wrist extension strength using a hand-held dynamometer, grip strength level through an electric dynamometer, and ROM through a smartphone goniometer application before and after intervention. Patient-rated tennis elbow evaluation, Visual Analogue Scale and Short Form 8 were measured by questionnaires. Results: There were showed significant differences among the VRE, WRE and control group in wrist extensor muscle and hand grip strength, ROM, elbow function, pain and QOL after intervention (p<0.05). The VRE group showed a greater significant improvement in wrist extensor muscle strength and elbow function compared with the others (p<0.05). The VRE and the WRE groups had a more significant improvement in wrist extensor muscle and hand grip strength, ROM and pain compared with the control group (p<0.05). However, there were no significant differences in QOL among the three groups. Conclusions: Combining VRE with thermotherapy and electrotherapy appears to be more effective in improving wrist extension strength, ROM, elbow function, QOL in tennis elbow patients.

One hundred and forty-eight cases of tennis elbow were treated by conservative managements firstly such as rest, medication, immobilization, physical therapy and local steroid injection, from Jan. 1985 to Jun. 1994 at Department of Orthopaedic Surgery, National Medical Center. Among the 148 cases, 16 cases who failed conservative managements, were treated with Nirschl & Pettrone operation. The results were summarized as follows, 1. Among the 148 cases, 110 cases$(74\%)$ were female, and 61 cases$(41.2\%)$ were in the age group 41 to 50, and mean age was 42.3 2. Ninety-nine cases were housewives and only 15 cases were related to sports. 3. The results 116cases$(78\%)$, of conservative treatment were excellent and good 10 fair and failure in 32 cases$(22\%)$, by Nirschl and Peettrone assessment. 4. Among the 16 cases who were treated with Nirschl and Pettrone operation, excellent result was obtained 10 7cases, good in 3 cases, fair in 4cases and failure in 2 cases. 5. Recurrence was developed in 18 cases$(12.2\%)$, and we obtained excellent & good result in 17 cases with both conservative and operative treatment. Above results suggest that the term, tennis elbow is a misnomer because it occurs more commonly in non-athletes such as housewives than in tennis players. So it seems to be a occupational disease rather than sports injury. Now, we propose eliminate of the term, elbow and substitute with terminology that described the true understanding and therapeutic orientation of it.

The purpose of this study was to analyze the shoulder joint torque and muscle pattern performing as Tennis serve by Isokinetic motions on Isomed 2000. The subject, who was 5 males Korean national high school tennis players. By analyzing the flexion/extension of the shoulder, the peak torque of the internal/external rotation motion(at 60,180 and 300 degree/sec) at peak torque degree, the weight, peak torque, and power. combined with the timing of the electrode of the attached trapezius and posterior deltoid at the three part. From the data analysis & discussion the following conclusions were drawn. When doing a shoulder extension, the peak torque can be widely seen at 60degree per second. However the degree may be different depending on angular velocity. When doing an internal rotation at 90degree abduction, peak torque per weight was seen at 60degree per second. The degree of peak torque was at 31.6-44.2 and peak power was faster when angular velocity was increased. The aspect of muscle pattern was seen more at the internal rotation in the 90degree abduction rather than the shoulder extension. However the angular velocity was not influenced by muscle mobilization(in order of anterior deltoid, posterior deltoid and trapezius. To properly apply the above conclusion, when tennis players serve it is better the elbow be impacted by the extension. when doing isokinetic motion it is better to increase angular velocity and improve muscle power. also the anterior deltoid amongst the shoulder muscle should be improved to develop serve speed.

최근 키보드나 마우스 조작이 아닌 사용자의 모션을 인식하여 플레이를 진행하는 체감형 게임에 대한 관심이 증대하고 있다. 일반적으로 이런 게임을 위해서는 사용자 모션을 감지하는 모션 콘트롤러가 필요하다. 본 논문에서는 사용자가 스마트폰을 손에 쥔 채 5가지 타입의 테니스 스윙을 할 때 발생하는 가속도 센서 값의 특징을 분석하고, DWT(Discrete Wavelet Transform) 기반의 테니스 모션 인식 방법을 제안한다. 우리의 방법은 스마트폰이 모션 콘트롤러 역할을 할 수 있게 함으로써, 사용자는 별도의 모션 콘트롤러를 구입할 필요 없이 손쉽게 체감형 테니스 게임을 즐길 수는 장점이 있다. 제안된 방법을 기반으로 테니스 게임 프로토타입을 개발하여 실험한 결과, 제안된 방법은 테니스 게임 진행에 충분히 높은 인식률을 보여 컴퓨터 게임에서 유용함을 확인하였다.

Purpose: This study was conducted to know the evidence case to assessment about literatures of extensor carpi radialis therapeutic strategy of tennis elbow about dysfunction wrist extension with anatomy, biomechanic and function. Method: Patient was received the physical therapy program with medication for two weeks. Physical therapy program consists of strengthening exercise, stretching exercise and extracopereal shock wave therapy. Results: Patients could do computer and house works at three weeks significant with improved pain. The amounts used repetitive muscle was reduced slowly over a period of a day or two days for wrist moving. Wrist flexor strengthening exercise and could reduced the wrist extensor injury. Conclusion: Clinicians certainly realized biomechanic effects and anatomy of extensor carpiradialis and elbow joint.

Muscle rupture is not a common disease. But it is known that partial muscle rupture commonly occurs to active sports athletes or heavy workers who receive severe physical stress. Gastrocnemius muscle rupture(this is called ‘tennis leg’)is often caused by sudden overstretching of the muscle through concomitant ankle dorsiflexion and knee extension. This rupture may result in a swelling and pain that is easily confused with other diseases like thrombophlebitis. Ultrasonography can confirm the clinical suspicion of tennis leg and the assessment of the size of the lesion, and can discriminate from other diseases. So it is a useful, noninvasive, low-cost modality to diagnose and follow up tennis leg. We experienced 2 cases of partial gastrocnemius muscle rupture patients who were treated by conservative methods or acupuncture therapy and followed up with Ultrasonography, and arrived at some interesting results, which we report along with a review of some relevant literature.

전국 규모의 경기에서 우승한 선수들을 포함한 남자대학 선수 8명을 대상으로 했다. 피험자의 4명은 펜홀더 그립, 4명은 세이크핸드 그립의 라켓을 사용하며 모두 오른손을 사용했다. 탁구의 포핸드 드라이브와 스매시의 라켓스윙동작과 관련된 각도성분, 스윙궤도, 스윙자세 등의 3차원 각운동 특성을 비교 분석한 결과 다음과 같은 결론을 얻었다. 라켓각(p<.05)과 라켓의 스윙각(p<.01)에서 두 동작 간 유의한 차이를 보였다. 스매시는 백스윙 자세에서 이미 라켓을 세워 라켓각을 크게 유지했으며, 라켓의 스윙각을 작게 해서 볼 스피드에 비중을 두는 것을 알 수 있었다. 또한 백스윙 자세에서 라켓헤드의 높이도 두 동작 간 큰 차이가 나타났다. 임팩트 순간 phg에서 두 동작 간 라켓 장축의 열림각의 차이가 크게 나타난 것을 보면, 볼에 순회전의 스핀을 넣기 위해서 약간 뒤에서 임팩트가 이루어진 것을 알 수 있었다. 백스윙 자세에서 상체의 기울기는 드라이브 동작에서 phg보다 shg에서 상체를 조금 더 구부리는 것은 중립 자세에서 라켓 그립의 구조적 차이로 인한 것으로 판단된다.
