Background: The characteristics of lateral epicondylitis (LE) are muscle strength weakness and increased common extensor tendon (CET) thickness. Ultrasonography has recently been used to evaluate tendinopathy. Diamond taping (DT) is commonly used to manage patients with LE. However, no previous studies have investigated the effects of DT on CET thickness. Objects: The aim of this study was to investigate the effects of DT applied around the lateral elbow on CET thickness, grip strength, and wrist extension force in healthy subjects. Methods: The subjects were 26 adults (13 male) in their twenties. First, the CET thickness was measured at rest. The CET thickness was measured by using ultrasonography at two points. The subjects were then instructed to perform maximal grip activities or maximal wrist extension activities before and after DT around the lateral elbow. The DT technique was applied using non-elastic tape. While the subjects performed maximal grip activities, the investigator measured the maximum grip strength (MGS) and CET thickness. Likewise, while the subjects performed maximal wrist extension activities, the investigator measured the maximum wrist extension force (MWEF) and CET thickness. Results: The MGS showed a statistically significant improvement after DT taping application in men (p < 0.05). The MWEF showed a statistically significant improvement after DT application in male (p < 0.01) and female (p < 0.05). When performing the activities, the CET thickness increased compared to that at rest. However, CET thickness didn’t show a statistically significant improvement before and after DT. Conclusion: This study shows that DT applied around the lateral elbow is effective in improving MGS and MWEF. However, it does not affect CET thickness.

본 연구는 테이핑 적용방법에 따른 근긴장도, 근경직도 및 악력의 변화를 알아보기 위해 실시하였다. 연구의 대상자는 20대 정상 성인 30명을 대상으로 하여 테이프를 늘리지 않고 붙이는 방법(non stretched taping)과 테이프를 늘려 붙이는 방법(stretched taping)을 통해 변인들을 측정하였다. 근긴장도와 근경직도는 Myoton pro 장비를 이용하여 측정하였으며, 악력계를 이용하여 악력을 측정하였다. 않은 자세에서 측정하였으며, 테이핑을 적용하기 전과 적용한 후를 대상자별로 임의로 순서를 정하여 측정하였고, 같은 동작에서 3번 측정하여 평균값을 사용하였다. 테이핑 적용에 따른 근긴장도, 근경직도 및 악력의 비교를 위하여 대응검정을 이용하여 분석하였으며, 중재 전·후에서 그룹간 차이를 보기 위하여 독립검정을 실시하였다. 본 연구의 결과 non stretched taping 적용과 stretched taping 적용 모두에서 근긴장도, 근경직도는 두 그룹 모두에서 통계적으로 유의한 감소를 보였으며, 악력은 두 그룹 모두에서 통계적으로 유의한 증가를 나타내었다. 그룹간 차이는 중재 전 근긴장도, 근경직도 및 악력은 차이가 나타나지 않았다. 중재 후 그룹간 차이는 근긴장도, 근경직도는 통계적으로 유의한 차이를 나타내지 않았으나, 악력의 경우 통계적으로 두 그룹간 유의한 차이가 나타났으며, stretched taping 그룹에서 더 높은 값을 나타내었다. 테이핑 적용 방법에 따른 근긴장도와 근경직도, 악력의 차이가 있기 때문에 테이핑 방법을 잘 적용하여 사용한다면 근육의 효과를 기대할 수 있을 것이다.

This study aimed to measure the grip strength of the dominant and non dominant hands of right-handed normal adults in the supination, pronation, and neutral positions of the forearms. The subjects of this study were instructed to make the standard posture suggested by the American Society of Hand Therapists (ASHT) in order to minimize the impact of changes in the posture of the body as follows. The grips strength was statistically different between groups (p<.05). In the follow up test using Scheffe test, the grips in the neutral position and supinator position did not show any difference, while the grip in the pronation was smaller than those of the above two other positions. The grips of the mainly used forearm and non-mainly used forearm of the study target did not show any statistically significant difference in the neutral, supinator and pronation positions of the forearm. This study is expected to provide basic information for studying the impact of the positions of the forearms on grip strength, assessing the prehensility of patients in clinical settings, and setting therapeutic goals.ㅍ

The purpose of this study is to analyze the grip strength by the girth of upper arm and forearm and their muscle activities by duration of grip strength. The subjects were consisted of 20 healthy adults(10 males & 10 females) who had no medical history of neurological and surgical problems with their arms. Girth of upper arm/ forearm and maximum grip strength for 4sec and 30sec were measured. Muscle activity was by wireless electrode EMG system. Co-relation of girth of upper arm/ forearm was significantly high. Upper arm's muscle activity performed for 4sec and 30sec was significantly high. In this study. It suggests that training of upper arm should be performed with the training of grip strength because both of upper arm and forearm affected grip strength.

In using both hands, everyone dominantly use one hand and it is called left-handedness or right-handedness person. Measurements of grip and pinch strength provide objective indexes to represent functional integrity of the upper extremity. This study was conducted for thirty female college students(19 right-handedness and 11 lefthandedness). For assessment of the type of handedness, questionnaire was used; for grip strength, Jamar dynamometer was used; for pinch strength, Jamar pinch gauge was used. In right handedness, the grip and pinch strength of the dominant right hand was significantly higher than those of the non-dominant hand. In addition, regular exercises were shown to give influences on reduction of strength gaps between dominant and non-dominant hands. In both groups of left and right handedness, the grip and pinch strength of the dominant hand were significantly higher than those of the non-dominant hand, and regular exercises were shown to give influences on reduction of strength gaps between dominant and non-dominant hand.

Grip strength is an objective indicator for evaluating the functional movement of upper extremities. Therapists have been using it for a long time as an excellent barometer for evaluating the therapy process, therapeutic effects and prognosis of patients with injuries in upper extremities. This study investigated the effects of extensor pattern position and elastic taping of non-dominant hand on the grip strength of dominant hand among general adults. The subjects of this study were 23 males and 7 females from physical therapy departments of 3 Universities located in Busan who agreed to participate in the experiment and the resultant data were analyzed using SPSS version 12.0. The results of the study were as follows. First, there was a significant difference between the grip strength of dominant hand when the non-dominant hand was at the neutral position and that when the non-dominant hand was at the extensor pattern position and both hands were at the maximum strength simultaneously (Bonferroni-corrected p<.001). Second, there was a significant difference between the grip strength of dominant hand when the non-dominant hand was at the neutral position and that when the elastic taping of non-dominant hand was applied (Bonferroni-corrected p<.001). Third, there was no significant difference between the grip strength of dominant hand when the non-dominant hand was at the extensor pattern position and both hands were at the maximum strength simultaneously and that when the elastic taping of non-dominant hand was applied. The irradiation effects through the extensor pattern position of non-dominant hand and application of the elastic taping to non-dominant hand showed significant results in improving the maximum grip strength of dominant hand. This finding could be suggested as the probability for the indirect treatment of the upper extremities of hemiplegia and orthopedic patients due to the long-term fixing of upper extremities.

Grip strength provides a quick and objective index of the functional integrity of the upper extremities. It is widely used as an assessment measure in physical and rehabilitation medicine. In this study, maximum voluntary grip strength of 20 college students wearing 5 different gloves were measured using Jamar hand dynamometer. The results show that maximum voluntary grip strength was generally reduced when wearing gloves as compared to bare-handed. More specifically, the grip strength was highest when wearing PVC coated glove or bare-handed and getting lowered as wrist band, rubber, leather, and cotton glove in these order. Depending on the measuring posture of grip strength, shoulder height with arm extended forward was higher than the elbow was flexed 90 degree. Moreover, subjects' demographic factors and hand dimensions were not closely related to the grip strength. It is thus recommended that the proper glove should be provided to reduce the negative consequences including dropping a tool, poorer control of a tool. lower quality work, and increased muscle fatigue and in turn to increase the user safety and satisfaction.

The purpose of this study is to find the standard value of hand width, of grip strength and of pinch strength by age, sex, and by left hand and right hand and also to find how the general characteristics influences grip strength and pinch strength. Martin Vigorimeter (List No. 17-27-01) was used for measuring grip strength, and the pinch gauge (0∼30 lbs) of B&L engineering for measuring pinch strength. The subjects of this study are the children at the age of three to seven years, who attending the babies' play room, kindergarten and the primary school in Seoul and the Kyungki province area. They all were normally developed without any significant neurology problem. wo hundred girls and two hundred boys were partifipated in this study. They were divided into ten subgroups according to the age of six month interval. Each group consisted of forty children of twenty boys and twenty girls. Analysis of data presents the technical statistics upon the hand width of right and left hand and the grip strength and pinch strength according to the age and sex. Multiple regression analysis using mixed liner model was operated in order to find how the general characteristics (of the age, sex, and side of hand) influence hand width, grip strength, and pinch strength individually. Also, we calculated the correlation among hand width, grip strength and pinch strength under the condition of controlling general characteristics; and to find correlation between the right hand and the left hand of the age and sex, we carried out paired t-test and came to the conclusion as follows: 1.　Hand width is significantly increased with the increase of age (p<0.01). The increase of hand width according to age, boy is wider than that of girl significantly (p<0.01), and the right hand is wider than that of the left hand significantly (p<0.01). 2.　Grip strength is significantly increased as the age and hand width increased (p<0.01). The increase of grip strength according to the age, boy is stronger than that of girl significantly (p<0.01), and grip strength of the right hand is stronger than that of the left hand(p<0.01). 3.　Three-jaw pinch strength is increased as the age, hand width and grip strength are increased(p<0.01). But there is no significant difference of three-jaw pinch strength according to sex and the side of hand(p>0.05). 4.　Tip pinch strength is significantly increased as the age and grip strength are increased(p<0.05). The increase of tip pinch strength according to the age, boy is stronger than that of girl significantly (p<0.05), but there is no significant difference between the right hand and the left hand(p>0.05). 5.　Lateral pinch strength is significantly increased as the age and grip strength are increased(p<0.01). But the increase of lateral pinch strength, there is no significant difference according to the hand width, sex and the side of hand(p>0.05). 6.　The test of correlation among hand width, grip strength and pinch strength showed the correlation between grip strength and pinch strength was stronger than the correlation between hand width and pinch strength(0.3<r<0.7). There was strong correlation between each pinch strength(0.3<r<0.7). Above all, the correlation of three-jaw pinch strength and tip pinch strength was strongest(0.7<r<1.0). 7.　The test of hand width according to the age and sex, and the difference between the right hand and the left hand in grip strength and pinch strength showed that there was significant difference against all the test of hand width, of grip strength, and of pinch strength in the age group from seven years and six months to seven years and eleven months than the age group under six years, specially in girls group(p<0.05).
