This study evaluated the dietary habits and dietary quality of the Korean elderly according to muscle strength status. This study was conducted on the elderly aged over 65 years who participated in the 2014-2018 Korea National Health and Nutrition Examination Survey. Subjects were classified into the normal muscle strength group(n=2,000) and the low muscle strength group(n=1,273) according to the handgrip strength. There was a significant difference in general characteristics, diet habits, and health behavior according to the muscle strength status. The normal muscle strength group had a higher total score of KHEI and a subtotal score of 「adequacy」 items. But there was not significant difference in the 「moderation」 items. For the 「balance of energy intake」 items, the normal muscle strength group had a higher subtotal score than the low muscle strength group only in among women. The prevalence of low muscle strength decreased in the highest quartile of the adjusted KHEI total score(p for trend=0.08). As a result of this study, it was found that KHEI was significantly associated with muscle strength. This study result can be used to provide dietary guidelines for the improvement of muscle strength in the elderly based on each item of KHEI and sex.

Purpose: This randomized study was done to compare the effects of a 6 month Tai Chi exercise and a self-help program on balance, flexibility and muscle strength in women with osteoarthritis (OA). Method: In this experimental study, 82 women with OA recruited from outpatient clinics or community health centers were randomly assigned either to a Tai Chi group or a self-help group. Thirty women (mean age = 62 years) in the Tai Chi group and 39 (mean age = 59 years) in the self-help group completed posttest measures (balance, flexibility, oxygen consumption, abdominal muscle strength, back muscle strength, and grip strength) at 6 months. Results: After the 6 month, Tai Chi participants had significantly greater balance (mean difference = 2.9 vs. 0.9 for the self-help), grip strength (mean difference = 4.6 vs. 0.9 for the self-help), and back muscle strength (mean difference = 4.1 vs. -0.3 for the self-help). However, flexibility, oxygen consumption, and abdominal muscle strength were not significantly different between the groups. Conclusion: Tai Chi increased balance, grip strength and back muscle strength in older women with osteoarthritis compared to the self-help program. Whether these changes improve physical functioning and fall prevention requires further study.

PURPOSE: The purpose of this study was to investigate the effects of trigger finger on pain, muscle strength and function in carpal tunnel syndrome (CTS) patients. METHODS: A total of 60 subjects (30 carpal tunnel syndrome with trigger finger and 30 carpal tunnel syndrome without trigger finger) were assessment for pain, muscle strength (power grip, key pinch , tip to tip pinch, three jaw pinch) and function. The effect sizes of the two groups were compared, and the correlation between the trigger finger and each variable was analyzed. RESULTS: The results showed that there were significantly difference in the pain, muscle strength excluding three jaw pinch and function (p < .05). The results also showed correlation between trigger finger and pain (r = .552), muscle strength excluding three jaw pinch (power grip r = -.296, key pinch r = -.260, tip to tip pinch r = -.285), and function (r = .375). The function of carpal tunnel syndrome patients was related to pain (r = .550) and power grips (r = -.324) of muscle strength. CONCLUSION: In carpal tunnel syndrome patients with trigger finger compared to carpal tunnel syndrome, muscle weakness, pain increase, and function reduction were shown. In addition, trigger finger are correlated with muscle strength, pain and function, and muscle weakness and increased pain affect the daily living of carpal tunnel syndrome patients with triggers finger. Therefore, physical therapy interventions of carpal tunnel syndrome patients with trigger finger should be combined with treatment for muscle strength enhancement as well as pain reduction.

Background: There have been many studies on self-myofascial release (SMR) stretching, but there are few comparative studies on the effects of massages using a release ball, which is a type of the SMR method. Objective: To investigate the immediate effects of release ball massage and self-stretching on proprioceptive sensory, hamstring's temperature, range of motion (ROM) muscle strength,. Design: Crossover study. Methods: Thirty women in 20's at S University in Busan voluntarily participated in the study. Participants were random to release ball group (n=15) or self-stretching group (n=15). Both groups performed 3 sets of exercises, stretching for 30 seconds and resting for 15 seconds in each position. The proprioceptive sensory, temperature of the hamstring muscle, ROM, and strength were measured before exercise, 5 minutes after exercise, and 30 minutes after exercise. Results: Release ball group showed significant differences in muscle length and temperature over time (p<.05). The comparison between two group over time showed significant differences in muscle length, temperature, and muscle strength (p<.05). Conclusions: These results demonstrate that release ball massage and self-stretching are beneficial for improving hamstring's temperature, ROM and muscle strength.

Purpose: The purpose of this study was to analyse the effects of Tai Chi on the muscle strength and flexibility. Method: 10 articles from Medline search of foreign journals(1981-2003) and 4 from Korean nursing journals (1981-2003) were surveyed. The research are analyzed according to research design, subjects, and dependent variables. Results: Research on Tai Chi Exercise increased rapidly in the 1990's. The experimental research design was more reported than the comparative design. The experimental design included; 21.4% one group pre-posttest design, 35.7% quasi-experimental design and 28.6% randomized design. Out of the subjects; 64.4% of papers were healthy older people, and 35.6% of papers were patients with osteoarthritis or rheumatoid arthritis. Style of Tai Chi was mostly used Yang or Sun form. Muscle strength was usually measured at lower extremity or grip strength. Classical Yang style or Long form was more effective to improve muscle strength. 75% of papers were significantly improvement in grip strength and 71.4% of papers in flexibility. Conclusion: To properly study the positive effects of Tai Chi exercise, it is suggested that meta analysis needs to be done to integrate the various results.

Purpose : This study was to explore the effects of knee joint taping exercise on muscle strength, bone mineral density, pain and IGF-1 in blood of elderly women with knee Osteoarthritis. Methods : Thirty elderly women with knee osteoarthritis were divided into three groups: the taping with exercise group (n=10), the regular exercise group (n=10) and control group (n=10). Participants' muscle strength, bone mineral density, pain and IGF-1 in blood were measured three times : before exercise, after 6 weeks, and after 12 weeks. Results : Participants in both exercise (taping & non-taping) groups showed improvement in muscle strength, bone mineral density, pain and IGF-1 in blood after 6 and 12 weeks compared to before exercise. In particular, the taping exercise group had a greater effect on muscle strength than the regular exercise group. Conclusion : Both exercise programs considerably improved muscle strength, bone mineral density, reduced pain and IGF-1 in blood in elderly women with knee Osteoarthritis. The knee joint taping exercise is perhaps a better exercise to improve muscle strength than the regular exercise in treating elderly women with knee Osteoarthritis

Purpose: This study examined the effects of heel raise exercises combined with neuromuscular electrical stimulation (NMES) on the muscle strength and postural control ability of subjects with functional ankle instability (FAI). Methods: Twenty-two subjects with FAI participated in this study. They were assigned randomly to two groups: 11 each in the NMES and the sham-NMES groups. Heel raise exercise was applied, and NMES electrodes were attached to the peroneus longus muscles. The NMES group applied NMES during the heel raise exercise. NMES was applied for 20 minutes during the heel raise exercise. The heel raise exercise was performed four times a week for five weeks. The muscle strength and balance error scoring system (BESS) were measured before and after the intervention. Results: A comparison of before and after the intervention within the groups revealed improved muscle strength in the NMES and Sham-NMES groups, but the BESS was improved under all conditions only in the NMES group. The Sham-NMES group showed no improvement in the unstable support surface. Furthermore, when comparing the amount of change before and after the intervention between the groups, there were significant differences in the total score and unstable support in the BESS and muscle strength. Conclusion: NMES had a positive effect on the functional activities of the functional ankle instability subjects, such as balancing on an unstable support surface during postural control and increasing muscle strength.

Purpose: This study aimed to investigate the correlation between abdominal muscle strength and measures of respiratory function in stroke patients. Methods: The study participants comprised 17 (male: 12, female: 5) stroke patients hospitalized at W rehabilitation hospital in Busan, South Korea. Abdominal muscle strength was assessed using a digital manual dynamometer for 5 seconds contacting the sternal notch of the participants to bend the trunk. Respiratory function (forced vital capacity, forced expiratory volume in one second, forced expiratory volume in one second/forced vital capacity, and peak expiratory flow) was assessed using a spirometer. The collected data were analyzed using Pearson's correlation analysis, and the significance level was set 0.05. Results: A statistically significant correlation was found between abdominal muscle strength and forced vital capacity, forced expiratory volume in one second, and peak expiratory flow. However, abdominal muscle strength and forced expiratory volume in one second/forced vital capacity were not significantly correlated. Conclusion: This study demonstrated that there is a relationship between abdominal muscle strength and respiratory function. Exercise programs to strengthen the abdominal muscles are therefore necessary to improve respiratory function in stroke patients.

Objective: The purpose of this study to investigate the correlations among the motor function, balance, and gait velocity and the strength that could explain the variation of gait velocity of chronic stroke survivors. Design: This was a cross-sectional cohort study. Methods: Thirty hemiplegic stroke survivors hospitalized in an inpatient rehabilitation center were participated. The muscle tone of ankle plantarflexor and muscle strength of ankle dorsiflexor were measured respectively with modified Ashworth scale (MAS) and hand-held dynamometer. And the motor recovery and function with Fugl-Meyer assessment (FMA), balance with Berg balance scale (BBS) and timed up and go (TUG) test were measured. Gait velocity was measured with GAITRite. The correlation among motor function, muscle tone, muscle strength, balance, and gait were analyzed. In addition, the strength of the relationship between the response (gait velocity) and the explanatory variables was analyzed. Results: The gait velocity had positive correlations with FMA, muscle strength, and BBS, and negative correlation with MAS and TUG. Regression analysis showed that TUG (𝛽=-0.829) was a major explanatory variable for gait velocity. Conclusions: Our results suggest that gait velocity had correlations with muscle strength, MAS, FMA, BBS, and TUG. The tests and measurements affecting the variation of gait velocity the greatest were TUG, followed by FMA, BBS, muscle strength, and MAS. This study shows that TUG would be a possible assessment tool to determine the variation of gait velocity in stroke rehabilitation.
