With diversity of mobile services (e.g., messenger, and social network service) on smartphone, the demand of text input using a soft keyboard is increasing. However, studies on subjective and physiological responses of users for various touch locations are lacking. The present study investigated the ergonomic effects according to touch locations of a soft keyboard on smartphone. The experiment of the present study measured perceived discomfort using Borg's CR-10 scale and electromyography (EMG) on forearm (abductor pollicis longus, and extensor digitorum communis) and thumb (abductor pollicis brevis, and first dorsal interossei) muscles. Perceived discomfort was significantly varied from 0.7 (extremely weak discomfort) to 2.5 (weak discomfort) depending on touch locations. %MVC according to touch locations was only significant at abductor pollicis brevis which varied from 10% to 23%. The experimental results of the present study can be utilized in the ergonomic design of a soft keyboard.

Purpose: Stenosing tenosynovitis is a stenosing condition of the sheath of the abductor pollicis longus and extensor pollicis brevis tendons at the radial styloid process. The purpose of this study was to investigate the effects of kinesio taping on the pain and grip power in patients with de Quervain's disease. Method: 20 female with de Quervain's disease was recruited. This procedure was performed with or without taping procedure. Pain levels were assessed using a visual analogue scale, and spherical and pinch grip powers were assessed using a dynamometer. Results: 1. Resting pain, Finkelstein test pain, and Tenderness using VAS scale was showed significantly reduced after taping application(p<0.01). 2. Spherical grip power using dynamometer was showed significantly increased after taping application(p<0.01). 3. Pinch grip power using dynamometer was showed significantly increased after taping application(p<0.01). Conclusion: So we thought that kinesio taping therapy had effects on the pain release and grip power increasing to the small or local muscle groups and joints.

Purpose: Pollicization typically involves surgical migration of the index finger to the position of the thumb. This procedure facilitates the conversion of a useless hand into a well-functioning one in patients who are not amenable to the toe-to-hand transfer. However, middle finger pollicization has been rarely reported. Materials and Methods: We reconstructed a thumb by immediate pollicization of the remnants of the middle finger in two patients who sustained a tumor and a trauma, respectively. The former, after cancer ablation was performed, has not been reported literally, and the latter involved free devitalized pollicization of the middle finger using a microsurgical anastomosis. The distal third extensor communis tendon was sutured to the proximal extensor pollicis longus tendon and the distal flexor digitorum superficialis and profundus were sutured to the proximal flexor pollicis longus. The abductor pollicis brevis tendon was sutured to the distal end of the first palmar interosseous muscle. Coaptation of the third digital nerve and the superficial radial nerve branch was performed. Results: Patients showed uneventful postoperative courses without complication such as infection or finger necrosis. Based on the principles of pollicization, a wide range of pinch and grasp movements was successfully restored. They were pleased with the functional and cosmetic results. Conclusion: Although the index finger has been the digit of choice for pollicization, we could also use the middle finger on specific occasions. This procedure provides an excellent option for the reconstruction of a mutilated thumb and could be performed advantageously in a single step.

De Quervain 씨 병은 장 무지 외전건과 단 무지 신건의 협착성 건막염으로 수부나 수근 관절의 반복적인 과사용에 의한 섬유막 비후로 발생한다. 진찰 소견상 요골 경상 돌기 주위의 동통과 압통이 흔한 증상이며 Finkelstein 검사에 양성소견을 보인다. 대부분의 환자는 보존적 요법에 좋은 임상 경과를 보이며 보존적 요법에도 불구하고 6개월 이상 증상이 지속되는 경우나 재발한 경우에 수술적 치료를 고려할 수 있다. 저자들은 동통을 동반한 종괴를 주소로 내원한 비전형적 De Quervain 씨 병을 초음파를 이용하여 진단하고 스테로이드 국소 주사로 치료하여 종괴의 감소 및 동통의 호전을 보인 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

De Quervain's disease is caused by stenosing tenosynovitis of the first dorsal compartment of the wrist. The first dorsal compartment at the wrist includes the tendons of the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). Patients with De Quervain's usually report pain at the dorsolateral aspect of the wrist with referral of pain toward the thumb and/or lateral forearm. This condition responds well to nonsurgical treatment. Objective : The aim of this study was to find out the therapeutic effect of the Cervus elaphus Herbal-acupuncture in the treatment of patients with De Quervain's Disease. Design : A prospective study of Cervus elaphus Herbal-acupuncture was conducted. Setting : The study was conducted in the Kang-nam Oriental Hosp. of Dong-Guk University. Patients : The study comprised 4 patients with De Quervain's Disease. Methods : We investigated 4 cases patients the De Quervain's Disease. We evaluated wrist function that before and after Cervus elaphus Herbal-acupuncture treatment by VAS score, tenderness and Finkelstein test. the treatment is operated every other day. Results : Pain reduction(VAS) was found out in the case treated with Cervus elaphus Herbal-acupuncture. Conclusions : Clinical results show that Cervus elaphus Herbal-acupuncture has a good analgesic effect in De Quervain's Disease.

Objective: The objective of this study was to describe the influence of smartphone usage on the upper limb muscles while in stable and unstable positions and during gait. Design: Cross-sectional study. Methods: The study was conducted with 20 right-handed university students between 20 and 27 years of age. Experiments were carried out on students who have used cell phones for more than a year. In this study, experiments were performed with one-handed and two-handed smartphone operations while on stable ground, and the same parameters were measured during smartphone use on unstable ground and during gait. Subjects were instructed to write a text message in Korean on the smartphone for 3 minutes. This was repeated 3 times, with a rest period of 10 seconds given between each 3-minute period. Electromyography was used to record the muscle activity of the upper trapezius, extensor carpi radialis, extensor pollicis longus, and abductor pollicis (AP) during phone operation. Results: The muscle activity value for the right AP in one-handed and the left-AP in two-handed operations was statistically higher than the other muscles in the stable position and during gait (p<0.0001). Also, the right AP in the one- handed operation condition was statistically higher than the two-handed condition (p<0.0001). Conclusions: The use of smartphones while in a stable position resulted in high muscle activity of the right upper limb AP. However, in an unstable position, there were no significant differences from the other muscle activities. Using smartphone while assuming various positions may lead to musculoskeletal disorders in different places.
