The aim of this study is to observe the effects of the shoulder stabilizing exercise using sling on the imbalance ratio of trapezius muscle activity and active range of motion (AROM) of shoulder joint. A total of 15 participants with chronic shoulder pain were participated and assigned into two groups; Intervention group that performed shoulder stabilization exercise for 4 weeks and control group that did not perform exercise. Muscle activities of the upper and lower trapezius muscle during 120-degree abduction and AROM during shoulder abduction were measured before and after 4-week intervention. As a result, there were significant changes both in the imbalance ratio and AROM after 4 weeks only in the intervention group (p < 0.05). In conclusion, shoulder stabilization exercise using sling would be effective in improving shoulder function by normalizing the imbalance ratio of muscle activity in terms of motor control.

The study was to investigate the effects of continuation, frequency, and time of physical activity after middle age on all-cause of mortality, and to determine the level of physical activity that should be recommended to Korean adults to reduce total mortality. Data of 3,871 participants in the Korea Longitudinal Study on Aging (KLoSA) who reported exercise habit at 2006 and follow-up until 2018 were analyzed using Cox proportional hazard model and chi-square tests to estimate the annual changes in probability of mortality and independent variables. In the fully adjusted model, the association between physical activity time and all-cause mortality was statically significant. With every 1-minute rise, hazard ratios (HRs) was 0.003 times lower (p = 0.019) for all-cause mortality. However, no significantly association between frequency and duration of physical activity and all-cause mortality. This study found that approximately over 65 min/week of physical activity regardless of the frequency or duration of physical activity reduced all-cause of mortality in Korean community-dwelling adults aged 45 years or more.

The aim of this study is to observe the effects of anodal tDCS applied over left prefrontal cortex on the chronic back pain, muscle strength and psychological fear. Thirty-three elderly aged 68 ± 6.27 years with chronic back pain participated. Participants were randomly assigned two group; Experimental group received 2-mA anodal current over left dlPFC with exercise for three days per week during 8 weeks while control group received sham current with exercise during the same period. Pain intensity, functional lift strength and fear-avoidance response of all the participants were evaluated. As a result, there were significant changes in pain intensity, muscle strength and activity-related fear toward the improvement (P < .05). In conclusion, the anodal tDCS on left prefrontal cortex would be effective to care the chronic pain of the elderly.
