Purpose: This study examined the effects of early stabilization exercise focused on the scapulothoracic joint on the recovery of surgical patients due to rotator cuff tear. Methods: The subjects were 30 patients divided randomly into two groups. Group I consisted of 15 patients who practiced shoulder joint stabilization exercises, including glenohumeral joint movement. Group II consisted of 15 patients who practiced scapulothoracic joint stabilization exercises, excluding glenohumeral joint movement. The duration of stabilization exercise was 30 minutes for one day, five days a week, and five weeks. To measure the dependent variables, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, range of motion (ROM), dynamometer of measured grip were used. Results: The DASH, ROM, and grip power were compared. A significant difference was observed before the intervention in each group (p<.05), and there was no significant difference between group I and group II (p>.05). Conclusion: Both shoulder joint and scapulothoracic joint stabilization exercises were effective after the intervention compared to preintervention, but there was no difference between the two groups. Unlike many recent studies on the initiation of stabilization exercises, this study allays the concerns between the advantages of 'early exercise' and oppositions of previous studies about 'early exercise'. Nevertheless, further research regarding these subjects is needed.

The palpation of spinous process and transverse process of vertebra are important part of the assesment and treatment from Orthopedic manual therapy. But the palpation area is descriptive differently each of literatures. So we generally got these outcomes. : There are C2, C3, C4 and C6 process as a bony landmarks and these are important part of establish the precise location of pain appears from cervical spine. Even though C7 process regard a prominent part, it is hard to distinguish C6 and process of T1. Thru that differentiation, grab the patient's forehead and try them cervical and hyper-extension check any movement of process or put on the fingers on C7 preocess and check the movement. The palpation of thoracic spine process is the land mark which determines general level orientation in the spine easily, there are T2, T7 spinous process. However, It is depends on how do you test the patient's arm when you palpate it and it can effect on spinous process. The transverse process of C1 is the only spot for palpation in cervical spine, and T1-3, T12 transverse process can palpate it when it stands on the process. The end of T4-6, T11 is placed on middle on vertebra of transverse process and transverse process. T7-9, T10 transverse process is place on same position as spinous process which is upper part of the spine.

In this paper, two procedures of enumerating the axial rotation are proposed using the unit sphere of the spherical rotation coordinate system specifying 3D rotation. If the trajectory of the movement is known, the integration of the axial component of the angular velocity plus the geometric effect equal to the enclosed area subtended by the geodesic path on the surface of the unit sphere. If the postures of the initial and final positions are known, the axial rotation is determined by the angular difference from the parallel transport along the geodesic path. The path dependency of the axial rotation of the three dimensional rigid body motion is due to the geometric effect corresponding to the closed loop discontinuity. Firstly, the closed loop discontinuity is examined for the infinitesimal region. The general closed loop discontinuity can be evaluated by the summation of those discontinuities of the infinitesimal regions forming the whole loop. This general loop discontinuity is equal to the surface area enclosed by the closed loop on the surface of the unit sphere. Using this quantification of the closed loop discontinuity of the axial rotation, the geometric effect is determined in enumerating the axial rotation. As an example, the axial rotation of the arm by the Codman's movement is evaluated, which other methods of enumerating the axial rotations failed.

In this study, we provided examples of light emitting diodes (LEDS) in everyday sportswear and confirmed their usefulness to provide functionality, aesthetics, and entertainment. One type of sports jacket and one set of sportswear were designed and manufactured using LEDs and made available to the general public for use in daily life to provide functionality, aesthetics, and entertainment. To generate digital images, a textural design of a circuit image was developed and applied, and the LEDs were placed on the developed textile in an attempt to merge the LEDs with the design. The product was equipped with a tilt sensor and produced a randomly lighted jacket with LEDs that adjusted according to movement. The LEDs turned on in the desired location by lifting the arm during night sports activities. The tricolor of NEO PIXEL LEDs lit randomly and its rhythmical design could be maximized when moving or exercising outdoors, and also for entertainment. The role of creating interest for lively and unexpected pleasures and the aesthetic beauty of LED lights were also obtained. There was no inconvenience or restriction of movement by LEDs or internal structures using the hot-melting technique, and the removable attachment of the device made it easier to wash.

Purpose: The objective of this case report is to examine the impact of physical therapy using the proprioceptive neuromuscular facilitation (PNF) concept for a patient with shoulder impingement syndrome. Methods: The patient is a 35-year-old female who has felt pain in the right shoulder for one month. The physical examination evaluated sensory integration, pain, joint integration and mobility, posture, reflex integration, range of motion, muscular strength, analysis of movement, and shoulder function. Comprehensive physical therapy was given to the patient, including stretching, mobilization, strengthening, posture correction, coordination improvement, daily activities, and sports exercises. The therapy was given 5 times a week for the first 5 weeks, then 3 times a week for the next 5 weeks. In all, the intervention lasted for 10 weeks. Results: The patient's senses, posture, and muscular strength all improved to a normal level. The degree of pain fell from 3/10 to 0/10 for activities taking place below shoulder height, and from 8/10 to 1/10 for activities above the head. Additionally, joint integration, motility, range of motion, and movements also improved. The disabilities of the arm, shoulder and hand (DASH) for functional evaluation improved from 27.5 to 10.3. Conclusion: Physical therapy using the PNF concept is effective in improving the body structure, function, activity, and participation of patients with motor disorders of the shoulder impingement syndrome.

The purpose of this study was to investigate the effects of active vibration exercise of upper limb on physical capacity index (endurance, grip strength, balance, and flexibility) and vasomotor index (capillary length and body surface temperature) in middle aged women. 20 participants randomly divided into two groups: vibro-swing exercise (VSE) and non vibro-swing exercise (NVSE). Subjects in each group measured the 30 second arm curl test, hand dynamometer, one leg standing test, back scratch test, nail fold capillary microscope (NFM), and digital infrared thermal imaging (DITI) before and after exercise. The results showed that active vibration exercise of upper limb with vibro-swing equipment increased the endurance, balance ability, and the capillary length. In addition, changes in body temperature immediately after exercise were predicted to affect vasomotor. Active vibration exercise of upper limb has the advantage of being able to exercise anywhere regardless of the location by inducing different frequency changes in movement of various ranges and velocity. For this reason, the combination of vibration and active movement can be expected the physiological effects when producing exercise programs for middle aged women.

Purpose: This study aimed: to confirm the balance ability of patients with spinal cord injury in the sitting state through a functional reach test using an elastic aid; and to propose a balance improvement plan. Methods: The study evaluated seven patients with spinal cord injury who could maintain a sitting posture through minimum assistance. A functional reach test was performed before and after wearing an elastic aid while sitting on a chair, and the effects before and after use of the elastic aid were compared and analyzed through a motion analyzer. Results: In the functional reach test, the forward movement distance of the hand was 97.45 mm before wearing the elastic aid, but significantly increased to 131 mm after wearing the aid (p<0.05). Corresponding forward movement distances for the shoulder were 81.26 mm and 113 mm (p<0.05 for the increase). There was no statistically significant change in lateral functional arm extension. Conclusion: It was confirmed, through a functional reach test, that trunk stability in patients with spinal cord injury increased with use of an elastic aid. In future, more efficient rehabilitation treatment programs will be possible if trunk stability in patients with spinal cord injury is improved by using elastic aids, and if various exercise treatments are also included in the rehabilitation programs.

전치의 후방 견인 시 적절한 치아 이동 상태 조절은 필수적이다. 설측 장치를 이용한 레버 암 길이의 조절을 통하여 치아 이동에 관한 연구는 있었으나 3차원적인 변위 양상에 대한 연구는 많이 이루어지지 않은 실정이다. 이에 본 연구는 상악 전치부의 레버 암(lever arm)의 길이를 5 mm 단위로 20 mm까지 증가시켰으며 대구치와 TPA (trans palatal arch) 상에 있는 견인 훅(hook)의 위치를 달리 하여 200 gm의 후방 견인력을 가했을 때 나타나는 치아 변위 양상과 응력분포를 3차원적 유한요소분석을 통하여 알아보고자 하였다. 이를 위하여 아시아 성인의 표본조사를 통해 제작된 치아모형(Nissan Dental Product, Kyoto, Japan)을 3차원적으로 스캐닝한 후 상악치아, 치주인대, 치조골에 대한 유한요소 모델을 제작하였다. 각 치아의 절단연과 치근첨의 이동량을 x, y, z 좌표에서 각각 계산하여 치열의 변위 양상을 분석하고 von Mises 응력 분포를 계측하였다. 연구 결과, 정상 교합 모형의 레버 암 길이가 15 mm, 20 mm인 경우 전치 절단연과 치근첨의 설측 변위가 유도되었다. 본 실험의 조건 중 20 mm에서 치근첨의 설측 변위는 최대로 나타났다. 구치부 견인 훅이 치근첨에 있을 때 대구치 치관은 원심 방향으로 변위되었다. 또한 레버 암의 길이가 20 mm인 경우 전치부의 정출은 미약하였고 견치 치관은 협측 방향으로 전위되었다. 이 때 구치부 견인 훅의 위치가 TPA의 구개 중앙 측에 있을 때보다 가장자리 측에 있을 때 견치 치관은 더 많이 전위되었다. 이상의 결과를 토대로 설측 장치를 이용한 상악 6전치의 후방 견인 시 레버 암의 길이가 길고 구치부 견인 훅의 위치가 구개 중앙부에 있을 때 전치부 절단연(incisal edge)의 정출 없이 견치의 측방 전위 및 전치부 절단연과 치근첨의 설측 변위가 공히 나타남을 알 수 있었다.

This study develops baseball uniforms for amateur baseball players with excellent appearance and functional movement. This study selected a conventional baseball uniform and developed a new one for amateur baseball players with improved function and appearance based on previous research results. In case of developed baseball uniform materials, this study used polyurethane mixed fabric for the top to improve flexibility. A mesh material was used at the armpit, back, and bottom of the top, side line of pants and pockets to improve breathability. In addition, quilted material was added to the knee to improve durability and protection. For the patterns and design, this study used a gusset under the arm to assist in comfortable movement as well as reduced the length of the top and circumference of the hem to decrease unnecessary parts. For the pants, this study used a waistband gripper to avoid the top riding up, added darts behind the knees to bend comfortably, and added additional fabric inside the hem to prevent dirt. In addition, we reduced the width and length of the pants. Wearing evaluation was divided into appearance evaluation by experts and on-site-wearing test by baseball players. The wearing evaluation results for the developed baseball uniform indicated higher evaluations than a conventional baseball uniform in all sections as well as showed significant differences in all sections. The result of movement adaptability evaluation showed the highest satisfaction for 'the top does not ride up' and 'dirt do not get in'.
