PURPOSE: This study examined the changes in the handgrip strength, dexterity, and hand function according to the presence or absence of gloves and types of gloves. METHODS: Seventy-six adults in their twenties (male: 24, female: 52, mean age 21.04 years) were the subjects of this study. The handgrip strength, dexterity, and hand function were evaluated with bare hands without gloves, poly gloves, and latex gloves. The handgrip strength was measured using a dynamometer, and three pinch strength tests were performed: tip pinch, lateral pinch, and three-jaw pinch. The hand dexterity was evaluated using the Minnesota manual dexterity test, and the hand function was evaluated using the Jabson-Taylor hand function test. RESULTS: There was no difference in the grip strength depending on whether the gloves were worn. The hand grip, dexterity, and hand function showed significant differences according to the type of glove. Regarding the handgrip, dexterity, and hand function, the latex glove had the best function, and the poly glove had the lowest function. CONCLUSION: There was a difference in dexterity among the hand functions but no difference in grip strength according to the type of glove. The results suggest that the use of latex gloves in daily life be recommended.

Background: This study investigated the effects of pelvic floor stabilization exercise of pain, disfunction, psychosocial, electromyography (EMG) activity on the lower back pain with postpartum. Methods: The study included 20 postpartum women who were randomly assigned to a sling exercise group (SEG, n=10) or a general physical therapy group (GPTG, n=10). Outcomes were assessed using to lower back pain with postpartum the quadruple visual analogue scale (QVAS), the Korean version of the Oswestry disability index (KODI), the fear avoidance belief questionnaire (FABQ), the inventory of functional status after childbirth (IFSAC), the edinburgh postnatal depression scale-Korean (EPDS-K), and trunk muscle activity before and after a 4-week exercise intervention. Statistical analysis were performed using a mean, standard deviation, crosstab test, paired t-test, independent t-test. Kolmogorove-Smirnov test was used for test of normality. Results: Compared to the GPTG, the SEG showed significant improvement in the QVAS, KODI, FABQ, IFSAC, and EPDK-K scores (p<.05) after 4 weeks. Conclusion: Postpartum pelvic strengthening exercise proved to have a positive effect.

Objectives: The study aimed to analyze the factors affecting the maturity of dental biofilm, which was assessed with quantitative light-induced fluorescence-digital(QLF-D), in a sample of Korean older adults. Methods: This cross-sectional study included 67 participants, aged 65 years and older. All participants completed a questionnaire and tests to measure their manual dexterity and handgrip strength, which are parameters that indicate hand function abilities. To evaluate dental biofilm maturity, 804 surfaces of six index teeth were imaged using QLF-D and then quantified as ${\Delta}R$ values. All data were collected from May 25, 2017 to April 30, 2018. The independent t-test, one-way analysis of variance, and step-wise multiple linear regression were performed to analyze the factors associated with the maturity of dental biofilm (${\Delta}R$). Results: The multivariate linear regression analysis revealed that the factor most strongly related to dental biofilm maturity(${\Delta}R$) was manual dexterity (${\beta}=-0.326$), followed by handgrip strength (${\beta}=-0.303$) and use of interdental cleaning devices (${\beta}=-0.283$) (p<0.05). Conclusions: Manual dexterity, handgrip strength, and use of interdental cleaning devices are factors that can predict dental biofilm maturity in adults aged 65 years or older. Therefore, the hand function of a patient should be evaluated first, before assessing the oral hygiene status of the patient or providing him/her with oral health education, and the dental hygienist should provide differentiated oral hygiene care depending on the patient's hand function ability. Finally, dental hygienists should help older adults to recognize the importance of auxiliary oral hygiene devices such as interdental brushes and keep motivating them to use the devices more frequently.

Purpose: Individuals affected by stroke present with changes in motor function, balance, and cognition. The purpose of this study was to the correlation between motor function, balance, and cognition in patients with stroke. Design: cross-sectional study design. Methods: 67 stroke patients in the experiment were included. For evaluation of motor function which is Manual Muscle Test, Range of Motion, Modified Ashworth Scale for spasticity, grasping power, and balance was measured using the Berg Balance Scale and Functional reach test. For evaluating Cognition which is Korean-Mini Mental State Examination. Results: The results of this study's motor function, balance, and cognition showed a significant positive correlation (p<0.05). Conclusion: The results indicated that motor function, balance, and cognition were significantly correlated with each other. Therefore, it is suggested that to improve the motor function and balance of patients with stoke, it needs to evaluate the cognition and the motor function, balance, and cognitive training should be combined.

Purpose : The purpose of present study was to determine effects of action observation training on upper limb function after stroke. Training was progressed to imitation and intensive training after observation to required action in ADL. Methods : Among the single case study was used to ABA design. pre base line(A) was only collected participant information without intervention in 5 times. action observation intervention(B) was carried out 10 times and 5 times to base lime(A) after intervention. Results : Results indicated that 10-second test, box and block test, manual function test was increased when compared action observation intervention(B) to pre base line(A). Conclusion : To stroke action observation training was evaluated gross manipulation, dexterity and upper limb function in related with ADL. action observation training benefits were maintained after intervention(B) and showed improvement on upper limb function of stroke.

Purpose: This study was conducted to determine how a manual therapy (joint mobilization and flexion-distraction technique) would affect pain and function with the chronic low back pain. Methods: Thirty patients were assigned to either the experimental group (n=15) or the control group (n=15). Patients in the experimental group performed joint mobilization and flexion-distraction technique. Patients in the control group performed spinal decompression therapy. Both exercises were performed for three days per week, for a period of six weeks. Pain was measured by the visual analogue scale (VAS) and functional disability was measured using the Oswestry disability index (ODI). A paired t-test was used for identify differences before and after treatment, and an independent t-test was used to identify differences between treatment groups. Results: In the within group comparison, the experimental group and control group differed significantly for all variables (p<0.05). However, no significant differences were observed in any variables between groups (p>0.05). Conclusion: The above results confirmed that it is necessary to confirm the various benefits of therapy with the joint mobilization and the flexion-distraction technique. The findings of the concerned study will be useful to doctors applying therapy to treat patients with the chronic low back pain.

With the growing traffic density and increasing comfort requirements, the automation of the drive train will gain importance in vehicles. The automatic clutch actuation relieves the drivers especially in urban driving and stop-and-go traffic conditions. This paper describes the dynamic modeling of a clutch actuator and clutch spring. The dynamic model of the clutch system is developed using MATLAB/Simulink, and evaluated by experimental data using a test rig. This performance simulator is useful to develop the clutch-by-wire (CBW) system for an automated manual transmission (AMT). The electro-mechanical type CBW system is also implemented as an automatic clutch for AMT. The prototype of CBW system is designed and implemented systematically, which is composed of an electric motor, worm gear and slider-crank mechanism. The test rig is developed to perform the basic function test of the automatic clutch, and the developed prototype is validated by the experimental data on the test rig.
