이 연구의 목적은 등속성 장비를 이용하여 고등학교 야구선수들을 대상으로 주관절 근육의 평가 기준치를 설정하는데 있다. 상지에 의학적으로 문제가 없는 고등학교 야구선수 201명을 대상으로 하였다. 주관절 검사는 HUMAC NORM(CSMI, USA) system을 이용하여 굴곡, 신전운동을 부하속도 $60^{\circ}/sec$에서 4회를 실시하였으며, 절대근력(peak torque)와 상대근력(peak torque % body weight)을 측정하였다. Cajori의 5단계(6.06%, 24.17%, 38.30%, 24.17%, and 6.06%)로 구분한 구간추정(interval estimation)방식에 의해 평가 기준치를 나타내었다. 이 연구의 결과에서 각속도 $60^{\circ}/sec$에서 주관절의 절대근력(peak torque) 굴근의 평균은 $37.88{\pm}8.14Nm$ 신근은 $44.59{\pm}11.79Nm$으로 나타났으며, 상대근력(peak torque % body weight) 굴근의 평균은 $50.06{\pm}8.66Nm$ 신근은 $58.28{\pm}12.84Nm$로 나타났다. 각속도 $60^{\circ}/sec$에서 주관절 굴근(flexer)과 신근(extensor)의 절대근력(peak torque)과 상대근력(peak torque % body weight)의 평가기준치는 설정하였다. 이 연구에서 분석 된 결과를 토대로 다음과 같이 결론을 이끌어 냈다. 주관절은 야구선수들에게 가장 많이 발생되는 손상임에도 불구하고 국내외 주관절 근력에 관한 연구가 미비한 실정이다. 주관절 손상을 예방하고 경기력 향상을 위해 상대적 근력 수준과 훈련효과를 보다 객관적으로 평가할 수 있는 근력 척도가 필요하다. 주관절의 절대근력과 상대근력의 평가기준치를 제시함으로서 고교선수, 야구지도자, 선수트레이너, 재활전문가 등에게 손상회복 및 재활 복귀 시 유용하게 자료가 될 것으로 생각되며, 객관적인 임상 평가 데이터로 활용하는 데 매우 유용한 정보라고 사료된다.

PURPOSE: This study was conducted to determine the effects of whole-body tilt exercise with visual feedback on trunk control, strength, and balance in patients with acute stroke. METHODS: The study included 18 patients with acute stroke who were randomly allocated to a Whole Body Tilt Exercise Group (WBTEG, N=9) and a General Trunk Exercise Group (GTEG, N=9). The WBTEG conducted whole-body tilt exercises with visual feedback, and the GTEG performed general trunk exercises. Both groups performed the exercises five times a week for 4 weeks. Outcomes were assessed using the trunk impairment scale (TIS), the trunk flexor and extensor strength test, the static balance test, and the Brunel Balance Assessment. RESULTS: After 4 weeks of intervention, both groups showed significantly improved TIS scores, muscle strength, and balance components (p<.05 in both groups). However, the improvement in TIS, muscle strength, and static balance in the WBTEG was significantly better than that in the GTEG (p<.05). CONCLUSION: Although both groups in this study showed post-intervention improvement, patients from the WBTEG who received visual feedback demonstrated more improvement. These findings indicate that whole-body tilt exercise with visual feedback may be effective at improving trunk control, trunk muscle strength, and balance in patients with acute stroke. Further studies are needed to gain a better understanding of the effectiveness of whole-body tilt exercise in patients with acute stroke.

Purpose: The purpose of this study was to evaluate the clinical results of the old Achilles tendon rupture treated with modified flexor hallucis longus (FHL) tendon transfer. Materials and Methods: Seventeen patients with old Achilles tendon rupture treated with modified FHL tendon transfer between March 2004 and February 2008 were enrolled in this study. Technically FHL was pass through the distal portion of the ruptured tendon instead of the drilled hole made on the calcaneus. The mean age of the patients was 37 years (range, 22~67 years), mean follow-up period was 28 months (range, 12~30 months). Patients' subjective satisfaction, calf circumferential diameter, range of motion of ankle and AOFAS ankle-hind foot score and Arner-Lidholm score was evaluated. Results: The average gap between the ruptured tendon was 52 mm (range, 47~56 mm). The AOFAS score improved from 47 pre-operatively to 91 points at the last follow-up. Sixteen patients were satisfied with the result free from discomfort, a patient had mild discomfort who had DM. fourteen patients had decreased range of motion less than 5 degrees while 2 patients had more than 7 degrees decrease compared to the intact side but had no discomfort in daily activities. Nine patients had less than 1 cm calf circumferential diameter difference and 7 patients had 1 to 3 cm diameter difference compared to the intact side. One who had more than 3 cm diameter difference had deteriorated muscle strength. Conclusion: Modified FHL tendon transfer can be a useful technique for the treatment of old Achilles tendon rupture when the gap is with large gap placed too proximal.

Objective: The purpose of this study is to investigate the differences in biomechanical variables of golf driving motion according to gender. Method: A total of 21 healthy golfers (11 men and 10 women) who have more than 5 years of professional experience and have been registered in the Korea Golf Association was recruited. A 250-Hz 8-camera motion capture system (MX-T20, Vicon, LA, USA) was used to capture the motion trajectories of a total of 42 reflective markers attached to the golfer's body and club. Moreover, two 1,000-Hz AMTI force plates (AMTI OR6-7-400, AMTI, MA, USA) were used to measure the ground reaction force. The mean and standard deviation for each parameter were then calculated for both groups of 21 subjects. SPSS Windows version 23.0 was used for statistical analysis. The independent t-test was used to determine the differences between groups. An alpha level of .05 was utilized in all tests. Results: There were differences in joint angles according to gender during golf driver swing. Men showed a statistically significantly higher peak joint angle and maximum range of angle in sagittal and frontal axis of the pelvis, hip, and knee. Moreover, women's swing of the pelvis and hips was found to have a pattern using the peak joint angle and range of angle in the vertical axis of the pelvis and hip. There were the differences in peak joint moment according to gender during golf driver swing. Men used higher joint moment in the downswing phase than women in the extensor, abductor, and external rotator muscles of the right hip; flexor and adductor muscles of left hip joint; and flexor and extensor muscles of the right knee. Conclusion: This result reveals that male golfers conducted driver swing using stronger force of the lower body and ground reaction force based on strength of hip and thigh than female golfers.

Objective: The endurance and strength of deep neck flexor (DNF) muscles have a major role on the function and stability of the cervical spine. In recent years, there has been a lack of research that have investigated the muscle tone of the superficial neck muscles. The purpose of this study was to examine the relationship of between contraction ratio of the DNF and sternocleidomastoid (SCM) muscles, DNF endurance, and muscle tension of the neck muscles. Design: Cross-sectional study. Methods: Forty-seven subjects (male=20, female=27) participated in this study. The muscle tone of the upper trapezius (UT), SCM, and suboccipital (SO) muscle was measured using a contact soft tissue tone-measuring instrument. For the contraction ratio of the SCM and longus colli muscle, the thickness of the relaxation and maximum contraction state of the SCM and longus colli muscles were assessed using a diagnostic ultrasound measuring instrument and a pressure biofeedback unit. The deep neck flexor endurance test (DNFET) was performed in a cranio-cervical flexion posture. The correlations between the measured variables were investigated. Results: The relationship between the DNFET and SO tone showed a significant negative correlation (p<0.05). The relationship between the DNFET and contraction ratio showed a significant positive correlation (p<0.01). There was no significant correlation between the DNFET and SCM and UT tone. Conclusions: This study confirmed that there is a relationship between DNF endurance, DNF activation, and SO tone. The information on the results of this study may be used as a reference that can be actively applied in the clinical environment.

Background: An 8-year-old girl had severe neck pain and stiffness after trauma. CT scan showed atlantoaxial rotatory subluxation (AARS). She had conservative treatment because she did not have neurological symptoms and spinal basilar artery dysfunction. Conservative therapy was halter traction twice for 4 weeks. However, pain and stiffness persisted. She had been recommended to have surgery from her physician, but she received manual therapy for non-surgical procedures. Methods: The joint mobilization, muscle energy technique, motor control exercise, and deep neck flexor (DNF) endurance exercise were applied as manual therapy and 10 session for 2weeks. Results: Clinical outcomes were measured at initial baseline, after 2 weeks, and after 6weeks. Active range of motion was completely restored after 6weeks and numeric pain rating scale was completely reduced after 2 weeks. The strength of neck flexor muscle recovered to normal after 2 weeks, and the DNF endurance was improved to 25 seconds after 2 weeks and to 42 seconds after 6weeks. Motor control capacity recovered to 30 ㎜Hg after 2 weeks. Conclusions: This case report describes the immediate and short-term clinical outcomes for a patient presenting with symptoms of neck pain following AARS. Clinical rationale and patient preference aided the decision to incorporate manual therapy as a treatment for this patient. Manual therapy has shown a successful recovery in AARS patients, more research is needed to validate the inference of this case report.

PURPOSE: A prospective study was conducted to investigate the correlation between the inspiration ability, bone mineral density, lumbar muscle strength, and muscular endurance for the national softball athletes in the national training center. METHODS: The general characteristics of study subjects, inspiration ability, bone mineral density, muscle strength, and muscular endurance data were analyzed using descriptive statistics. In addition, the Pearson product moment correlation was performed to investigate the correlation between the inspiratory capacity, bone mineral density, muscle strength, and muscular endurance. RESULTS: The inspiration, flow rates, and volume were not correlated with the bone mass and bone mineral density. Inspiration and the flow rates and volume were not correlated with the bone mass and bone mineral density. On the other hand, inspiration was correlated with the Extensor muscles (r=.464, p=.006) at an angular velocity of 60°/s and the flexors (r=.463, p=.006) and extensor muscles (r=.615, p<.001) at an angular velocity of 180°/s. The flow rate was also correlated with the extensor muscles (r=.444, p=.009) at an angular velocity of 60°/s and with flexor muscles (r=.432, p=.011) and extensor muscles (r=.589, p<.001) at an angular velocity of 180°/s. Finally, the volume was correlated at the extensor muscles at an angular velocity of 180°/s (r=.534, p=.001). CONCLUSION: The correlation between the inspiratory capacity, bone mineral density, muscle strength, and muscular endurance of softball athletes did not correlate with the bone mass and bone density. On the other hand, the lumbar muscle strength increased with increasing inspiratory capacity.
