Objectives: This study aimed to assess hand grip strength and femoral neck bone mineral density levels among Korean fishery workers and investigate their association. Methods: Hand grip strength and femoral neck bone mineral density were measured in a survey and health examination conducted in 2021 among fishery workers in a southern region of South Korea. Covariates including gender, age, education level, income level, smoking behavior, drinking behavior, family history of hip fractures, use of calcium and vitamin D supplements, hypertension, diabetes, regular exercise, and body mass index were investigated. Multiple regression analysis was employed to assess the association between hand grip strength and femoral neck bone mineral density. Results: Among 147 fishery workers, 8.16% exhibited low hand grip strength levels indicative of possible sarcopenia, and a significant association was found between low hand grip strength and decreased femoral neck bone mineral density (β = -89.14, 95% CI = -160.50, -17.78). Additionally, factors such as women gender, advanced age, family history of hip fractures, and a body mass index below 25 kg/m² were associated with decreased femoral neck bone mineral density. In the subgroup analysis by gender, a correlation between low hand grip strength and decreased femoral neck bone mineral density was observed only in men. Conclusions: Further research is needed to explore various determinants and intervention strategies to prevent musculoskeletal disorders among fishery workers, ultimately enhancing their quality of life and well-being.

Purpose: The purpose of this study was to explore the effects of hand acupoint massages on ADL ability and grip strength of stroke patients. Method: This study was designed as a quasi-experimental nonequivalent control group for pre and post-test. Twenty-eight patients were assigned to the experimental group and thirty to the control group. The hand acupoint massage was applied to both hands of the experimental group for sixteen minutes each time, a total of 15 times during five weeks. The patient's ADL ability and grip strength were measured before and after the program. The data were analyzed with mean. percent, chi-square, a paired t-test and t-test. Result: The level of ADL ability was significantly higher in the experimental group than in the control group. Also, the level of grip strength was significantly higher in the experimental group of the plegic side than in the control group, but not in the normal side. Conclusion: We have found that the hand acupoint massage helps the stroke patients improve their ADL ability and grip strength.

In this study, the nutrient intakes, dietary quality, and muscle strength of elderly women in a social-welfare center of a large city were compared with those of elderly women at home in a large city. Also, the relationships between muscle strength and nutrient intake status were investigated in both elderly group. The results of this study were as follows: The ages of elderly in the social welfare center and of elderly in general home residing elderly were 68.2 and 70.3 years, respectively. The average energy and nutrient intakes of both groups were lower than the Korean RDA. There were no differences between the groups in terms of macro-nutrient composition and quantity. The elderly in center showed significantly lower intakes of vitamin $B_2$, niacin and calcium than the home-residing elderly. The hand grip strength and back muscle strength were lower in the elderly of social welfare center, but a significant difference was found only in the left hand grip strength. The muscle strength, especially the left hand grip strength of those in social welfare center, showed significant correlations with various nutrient intakes. In contrast, generally no relationship between muscle strength and nutrients intakes status could be found in the home residing elderly. The variances in the mean hand grip strength and the left hand grip strength 19.0% and 18.6% respectively, were explained by their ages. This is in contrast to 22.3% and 32.4% of calorie intake and vegetable protein intake in the elderly of the social welfare center. In conclusion, the status of nutrient intake in those in the social welfare center seems to be low, and it is assumed that the low calorie and vegetable protein intake may contribute to the muscle strength decline in the socioeconomically high risk elderly.

Purpose: This study examined the effects of a paraffin treatment with exercise on the muscle strength and fatigue of the hand according to the use of smartphones. Methods: The measurement subjects were 30 healthy males in their 20s who were divided randomly into the control and paraffin treatment groups. A typing exercise using a smartphone was performed. The pinch grip force was measured to evaluate the muscle strength of the thumb, and muscle fatigue analysis using electromyography was performed to analyze muscle fatigue. Results: The functional changes to the arm and the fatigue of the hand through the use of a smartphone were examined to determine the effects of the paraffin treatment. The dominant hand-pinch grip force test did not show a significant difference, but the non-dominant hand-pinch grip force test showed a significant difference between the groups (p=0.030). In the dominant hand fatigue test, there was a significant difference between the groups (p=0.037). In the non-dominant hand, there was a significant difference between time (p=0.012) and the groups (p<0.001). Conclusion: The effects of paraffin intervention on the hand muscle strength and fatigue due to repeated use of the smartphone were confirmed. These results can be used as a basis for clinical use and can be a guide for the correct use of smartphones, which are essential in modern life.

In this paper, muscular activity and muscle fatigue of FDI(first dorsal interosseous muscle) and thenar muscle of hand was analyzed with surface EMG signal based on four kinds of attitudes(grip, tip, key and palmar) to measure grip strength and pinch strength after hand operation and rehabilitation treatment. The normative data are needed to interpret evaluation data to assess a patient's ability to return to labor environment. The preceding researchers proposed the standard data only by studying on maximum grip strength and the maximum pinch strength followed by each attitude of subjects' hands. But in this study, the muscle activity and muscle fatigue were considered under the various attitude to propose normative data. As a results, the muscle fatigue may be used only for presentation of normative data in labor environment.
