Objectives : This study was to evaluate the effects of acupuncture at Sang-Baek, Dong-Si acupuncture point, for the patients with sprain of the wrist pain(snuffbox region). Methods : To randomize, We tossed a coin, so 36 patients were divided into two. Group A of 19 persons was treated with common acupuncture treatment, and Group B of 17 persons was treated with acupuncture of Sang-Baek. We evaluated the treatment effect of each group by Visual Analogue Scale and Modified Mayo Wrist Score. Results : After 7days from the baseline, in VAS, Group A is $4.84{\pm}1.80$ and Group B is $3.35{\pm}2.06(P=0.038)$. In Wrist Score, Group A is $26.47{\pm}18.70$ and Group B is $44.64{\pm}27.76(P=0.034)$ Conclusion : We knew that acupuncture of Sang-Baek is more effective.

Background: This study was conducted to evaluate the clinical effect of acupotomy, a newly upcoming acupuncture treatment method for a dorsal wrist ganglion cyst. Methods: A patient with a dorsal wrist ganglion cyst was treated with acupotomy under ultrasonographic guidance. The symptoms caused by the cyst and size of the cyst under ultrasonographic observation were used to evaluate the effect of the acupotomy treatment. Results: The numeric rating scale score reduced from 7 to 1.4 throughout the treatment period. The size and swelling of the cyst decreased following acupotomy treatment. Conclusion: Acupotomy had a positive clinical effect in the treatment of a dorsal wrist ganglion cyst in this case. Further studies are required for its additional retrospective application.

Vascularized free fibula head transfer is an established method for reconstruction of long bone defects of the upper limb involving the distal radius or the proximal humerus. For the wrist following tumor resection, in cases of resection of the radial articular surface, three reconstructive options are possible: 1. fibular head transfer to replace the radial joint surface, 2. fixation of the fibula to the scaphoid and lunate, 3. complete wrist fusion. The decision on the type of the operation depends on the amount of the resection and the remained normal anatomical structures, and also the necessity of function of the wrist in the future. The authors believe that the vascularized free fibula head graft is a safe and reliable method for reconstructing the upper limb, especially for patients with a defect of the distal radius, and report the operative methods, donor vascular consideration, complications, and functional result after this operation.

In this study, we constructed a four-channel impedance measurement system including a two-channel goniometer to analyze human arm movement. Impedances and joint angles were simultaneously measured for wrist and elbow movements. As the impedance changes resulting from wrist and elbow movements depended heavily on electrode placement, we determined the optimal electrode configurations for those movements by searching for high correlation coefficients, large impedance changes, and minimum interferences in ten subjects (age: 29+6). Our optimal electrode configurations showed very strong relationships between the wrist joint angle and forearm impedance (correlation coefficient = 0.95+0.04), and between the elbow joint angle and upper arm impedance (correlation coefficient = -0.98+0.02). Although the measured impedances changes of the wrist (1.1+1.5 ohm) and elbow (-5.0+2.9 ohm) varied among individuals, the reproducibilities of wrist and elbow impedance changes of five subjects were 5.8+1.8 % and 4.6+1.4 % for the optimal electrode pairs, respectively. We propose that this optimal electrode configuration would be useful for future studies involving the measurement of accurate arm movements by impedance method.

The wrist and forearm are a frequently damaged area in high tension electrical injury as an input or output of the current. Electrical burns affecting the wrist and forearm may produce full thickness necrosis of the skin and damage deep vital structures beneath the eschar, affecting the local tendons, nerves, even bones and joints which result in serious dysfunction of the hand. From January 1997 to December 2001, we had treated 20 patients with high tension electrical burn in the wrist and forearm using anterolateral thigh free flap. Average follow up period were 24 months and we get satisfactory results both in functional and aesthetic aspects. This flap is considered useful in one-stage reconstruction of wide and large soft tissue defect combined with arterial injuries.

This paper deals with a Capstone Design project which is a wearable haptic wrist massage device design carried out within the 'Designeer' education program. Following design thinking process is recommended throughout a year in order to ensure a desirable, feasible and viable product. Dealing with a real problem of the field requires open-minded and flexible attitudes both from students and professors. Integrating design in an engineering project does not mean always making better looking product. User experience design allows wider opportunity to engineers to deal with design. A case study of developing a wearable wrist massage device shown in this paper demonstrate haptic design and how haptic properties can be optimized to offer best user experience of hand massaging. This study identified that starting lateral pressure movements from the center in larger area using air tubes gives better feeling as self-massage using wrist wearing devices.

Objectives : This study aims to evaluate current clinical evidence of traditional Korean medicine treatment on wrist pain with carpal tunnel syndrome. Methods : Ten Korean databases were searched for prospective clinical trials of traditional Korean medicine therapy on wrist pain with carpal tunnel syndrome from the time of their inception to February, 2015. Studies conducted in Korean, Chinese and English were searched. Risk of bias in included non-randomized controlled trials was assessed by the Cochrane handbook procedure. Results : Four non-randomized controlled trials were included. A high risk of bias was observed in all trials. All of the included studies reported favorable effects being experienced by an intervention group compared to a baseline or control group. Included studies never described any occurrence of adverse events. Conclusions : There is no evidence that traditional Korean medicine treatments are effective for treating wrist pain associated with carpal tunnel syndrome. All of the included studies lacked appropriate methodological qualities and internal validity. Future well-designed clinical trials that evaluate the effects and safety of traditional Korean medicine treatment for patients with carpal tunnel syndrome are needed.

The purposes of this study were 1) to determine the changes between pre-treatment and post-treatment of four groups of 15 persons each and 2) to compare the effect of conventional transcutaneous electrical nerve stimulation(TENS) and laser at auricular acupuncture points on experimental pain threshold measured at the wrist. Sixty healthy adult men and women(M:32, F:28), aged 20 to 28 years, were assigned randomly to one of four groups. Group 1 received TENS to the appropriate auricular point for wrist pain, Group 2 received laser to the appropriate auricular point for wrist pain, Group 3 received placebo TENS to the appropriate auricular point for wrist pain, Group 4 received no treatment and served as controls. Experimental pain threshold at the wrist was determined with a painful electrical stimulus before and 20 minutes after ear stimulation. Group 1 was the only group that showed a stastically significant increase (p<0.05) in pain threshold after treatment whereas the Group 2,3 and 4 did not. These results suggest that TENS has the capability to higher pain threshold but laser does not.

In this paper, we propose a method for recognizing eating behavior with almost no motion acceleration. First, by using the acceleration of gravity acting on the wrist direction, we calculate the angle between the gravity and the wrist direction. After that, detect wrist reciprocating motion when peak and vally exist in specific angle band. And then, when accumulate the number of wrist reciprocating motion occurrences are up to 10, then regard as the meal time 5 minutes before the detection time. Also, estimate the meal time only if its duration is more than 7 minutes. Using the data of 2128 minutes, which was collected from four graduate student, the result of the meal time estimation shows 95.63% accuracy.

Purpose: This paper was to develop an elbow restraint which can reduce the side effects of the wrist restraint which was frequently used in an intensive care unit and to evaluate its application. Methods: A nonequivalent control group non-synchronized design was used. Subjects were 38 patients (elbow restraint group: 18, wrist restraint group: 20) and 20 nurses who used both restraints in medical intensive care unit at G National University Hospital. Restraints were applied to subjects for 72 hours. Data were collected from December 1, 2009 through March 31, 2010. The data collected were analyzed using $x^2-test$, Fisher's exact test, t-test, and ANCOVA using SPSS 12.0 program. Results: Elbow restraint significantly decreased range of wrist motion reduction, swelling and significantly increased the convenience of wearing restraint compared to wrist restraint. Conclusion: The new elbow restraint are more efficient than the old wrist restraint, which have been used in an intensive care unit, in terms of convenience of restraint application, range of joint motion and prevention of swelling.
