본 연구는 스마트 폰 사용 시 팔의 지지 각도에 따라서 엄지손가락과 나머지 손가락의 기능에 미치는 영향을 알아보고자 하였다. 이 연구는 2014년 4월 21일부터 27일 까지 진행되었다. 연구 대상자는 21명의 건강한 성인을 대상으로 하였으며, 총 3그룹으로 나누어 진행하였다. 지지대 없이 90도의 각도를 유지하고 스마트 폰 타자를 실행한 그룹, 슬링을 이용하여 90도 각도를 유지하고 스마트 폰 타자를 실행한 그룹, 슬링을 이용하여 120도 각도를 유지하고 스마트 폰 타자를 실행한 그룹으로 나누었으며, 각 그룹은 7명씩 나누었다. 손의 통증을 측정하기 위하여 핀켈스타인 검사를 하였으며, 시각 통증 척도를 이용하여 결과를 나타내었다. 또한 손의 악력과 엄지손가락의 핀치 그립을 측정하였다. 각 측정은 왼손과 오른손을 측정하였으며, 시작 전, 30분, 1시간, 1시간30분으로 총 4번 측정하였다. 본 연구의 결과는 왼손과 오른손의 통증, 악력, 핀치 그립의 시기에서 유의한 차이를 보였으며(p<.05), 오른손의 악력에서는 시기와 군의 교호작용에서 유의한 차이를 보였다(p<.05). 이 결과로 인하여 팔의 지지는 손의 스트레스를 줄여 손의 기능에 도움을 준다고 생각된다.

The purpose of the study is to prevent pain and malfunction of the hand by correcting the angle of holding a smartphone. Subjects comprised of 21 healthy students. This research was conducted from April 21 2014 to April 27 2014. The three groups were as follows: first group included 7 students who held the phone at an angle of 90 degrees without a sling, and second group included 7 students who held the smartphone at an angle of 90 degrees with a sling; and the third group included 7 students who held the smartphone at an angle of 120 degrees with a sling. VAS was measured through the Finkelstein Test. Also, pain rating and muscle strength were assessed four times 30 minutes before and after the experiment for one and a half hour with pinch grip, dynamometer, and visual analogue scale. Smartphone was used. In all of the measurements, period showed a significant difference (p<.05) between both sides and a significant difference was not found between the group. In the time ${\times}$ group, pain score and grip strength were significantly different in the right side only (p<.05). According to the results of this experiment, providing support to the hand helps to increase the hand function by reducing the stress.

문제 정의
The aim of this study was to evaluate the effect of the support provided by the sling on the pain and function of the hand due to the repetitive use of the smartphone. Injuries to the wrist and hand were the most prevalent.
제안 방법
The sling helps to fix the angle of the hand and VAS was measured through the Finkelstein Test. Also, the pain rating and the muscle strength were assessed four times 30 minutes before and after the experiment for one and a half hour with pinch-grip, dynamometer, and visual analogue scale. Smartphone (G2, LG, Korea) was used.
The B & L Engineering Pinch Gauge Hydraulic Hand Dynamometer was used in this study for measuring the grip strength and holding power in order to evaluate the function of the hand.
The purpose of the study is to prevent pain and malfunction of the hand by correcting the angle of holding a smartphone.
In recent times, studies of hand kinetics analyzed the force, moment, and torque of the fingers and tendons. These studies used a tendon-force- measurement system[7], force transducers[8], dynamometers[9], force gloves[10], and pinch gauges[11] to take measurements. The tendon forces from the extrinsic muscles of the hand have been measured directly by instrumenting the tendon[12].

Also, the pain rating and the muscle strength were assessed four times 30 minutes before and after the experiment for one and a half hour with pinch-grip, dynamometer, and visual analogue scale. Smartphone (G2, LG, Korea) was used. Typing was performed via a smartphone app [fig.
Subjects comprised of 21 healthy students and they were divided randomly into three groups. These three groups were as follows: the first group, a control group [Fig.
The study was conducted in three different groups of students of "H" university in Gwangyang, Jeollanam-do province, South Korea [Table 1].
Thus, the fingers have metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints, whereas the thumb has carpometacarpal (CMC), MCP, and interphalangeal (IP) joints. The wrist contains the following eight bones: the hamate, pisiform, triquetral, capitate, lunate, trapezoid, trapezium, and scaphoid. In total, the hand has 27 bones and 28 muscles[5].
데이터처리
0 (SPSS, IBM, USA) was used to analyze all collected data. The analysis of covariance (ANOCVA) of variance test was performed to determine intergroup differences. Statistical significance was set at a p value of less than .
이론/모형
Finkelstein test was used to measure the pain in hands, visual pain scale was used to measure the pain (visual analogue scale: VAS), and it was conducted during the Finkelstein test. Finkelstein test is performed to assess pain when the thumb is bent inwards in a state of wrist ulnar deviation.
성능/효과
At the lowest torque value of 120°, the muscles of the hand showed the maximally reduced load lifting aspect. The study of the supporting arm according to the angle of the arm showed the effect of reducing the pain in the hand, it was confirmed that to reduce the hand of the depression.
